  1. Bosch are one of the biggest players in driver assist technologies. They're also working on how those technologies can be applied to biking. Get a heads up here:

    = = = = = = = = = = = = = = = = =


    Estimates show that nearly 90 percent of all crashes are caused by driver error, making advanced safety systems an important focus for automakers and governing agencies. Bosch offers a plethora of active and passive safety technologies, including driver-assistance functions that can help reduce the number of accidents and save lives.

    How many lives are lost in traffic accidents each year? According to the United Nations, worldwide nearly 1.3 million lives are lost in traffic accidents each year and this number could rise to nearly 1.9 million in the next 10 years.

    Bosch, on the other hand, thinks it has a solution by approaching the problem in three areas:
    1. Driver assistance systems: Use the information from surrounding sensors to enable safe and comfortable driving
    2. Active Safety Systems: Intervene before accidents occur, helping to reduce serious injuries and fatalities
    3. Passive Safety Systems: Help to reduce injuries by protecting occupants in crash situations

    Which is best? Actually that’s the wrong question, because each has its unique part to play. And the release from Bosch indicates that it is more than ready to offer OEMs reliable systems.

    “At Bosch, we are focused on developing systems that bring the world closer to accident-free driving,” said Scott Winchip, regional president, Chassis Systems Control North America, Robert Bosch LLC. “Safety technologies, such as predictive emergency braking systems and anti-lock brake systems for motorcycles, can help reduce the number of injuries and fatalities caused by traffic accidents, as well as the associated costs.”

    1. Driver Assistance Systems
    Bosch’s driver assistance systems help drivers avoid accidents by using intelligent sensors to detect critical situations. Key driver assistance technologies include the following:

    • Predictive Emergency Braking System (PEBS) – Bosch’s PEBS is based on the networking of a radar sensor with Electronic Stability Control (ESC) in three stages. It can assist in reducing rear-end crashes through its three-stage approach, thus offering drivers advanced warning for improved braking reaction time in critical situations, and assistance in avoiding crashes or reducing the risk of injury in crashes that are unavoidable

      Stage 1: Predictive Collision Warning (PCW) identifies the risk of a collision and prepares the brake system to ensure the driver has access to full braking power. This preparation is followed by an audible and/or visual signal and an optional haptic alert (i.e., brake pulse), which signals the driver to react by braking or taking evasive action to avoid a rear-end collision. The timing of the warning is calculated using a radar sensor that continuously evaluates the distance and speed to the preceding vehicle.

      Stage 2: Emergency Braking Assist (EBA) extends the warning by providing intelligent braking support. The system’s radar sensor continues to evaluate the distance and time to collision to the preceding vehicle and calculates the additional brake pressure required to avoid the collision. If the driver brakes after the collision warning, but fails to apply sufficient brake force, EBA automatically increases the brake pressure.

      Stage 3: Automatic Emergency Braking (AE8) provides braking support on multiple levels to help avoid collisions. First at low speeds (under 18 mph) often preventing rear-end collisions altogether. Second, when the driver does not react to the collision warning, the function initiates partial braking to decelerate the vehicle and provide additional time for the driver to respond. Finally, in situations where the driver does not react to the collision warning and the system detects the rear-end collision is unavoidable, full braking is triggered. For partial and full emergency braking, Bosch recommends the radar sensor be supplemented with video technology.

      Adaptive Cruise Control (ACC) reduces driver stress by automatically controlling the vehicle’s speed and maintaining a predefined minimum distance to the preceding vehicle using a radar sensor. Standard ACC can be activated from speeds of around 20 mph and up and supports the driver primarily on the freeways and long hauls. ACC Stop and Go controls the speed and distance to the preceding vehicle down to vehicle standstill, supporting the driver in heavy traffic situations

      Mid-Range Radar Sensor (MRR) – The new Bosch MRR sensor supports functions such as ACC and PEBS. Working the same way as the existing long-range radar sensor (LRR3) in the 77 GHz frequency band, it records the distance and position of obstacles with precision and at far less cost. This sensor also can be used in the rear of the vehicle to support functions such as blind spot detection, cross traffic alert and lane change assist.

      Lane Departure Warning (LDW) – Bosch’s LDW uses a video camera to detect lane markings ahead of the vehicle and monitor the vehicle's position in its lane. When the function detects that the vehicle is about to unintentionally leave the lane, it warns the driver through a visual, audible and/or haptic signal (i.e., steering wheel vibration). The function does not issue a warning when the driver activates the turn signal to change lanes intentionally.

      Lane Keeping Support can actively help the driver remain in the marked lane by using a video camera to detect if the vehicle is getting too close to the side of the lane and then taking action to correct the vehicle’s position. When connected with electric power steering, the system will provide a gentle, but noticeable steering torque to prompt the driver to keep the vehicle in the lane. For vehicles without electric power steering, lane keeping support is achieved by applying braking torque to individual wheels. The driver remains responsible for control of the vehicle and can override the system at any time. When the driver activates the turn signal to intentionally change lanes, the function does not intervene.

      Driver Drowsiness Detection identifies when a driver is at risk of falling asleep and sends a warning to remind the driver of the danger of driving while tired, thus assisting in averting a potential crash. The system operates by analyzing the driver’s steering behavior using data collected from a steering angle sensor or electric power steering system. It identifies “deadbands,” or phases where the driver does not steer for a brief period and then makes an abrupt steering correction. The system combines the frequency and strength of these reactions with other data, such as vehicle speed and time of day, to calculate a tiredness index. If this index exceeds a specific value, an audible, visual (i.e., flashing coffee cup) or other alert mechanism can warn the driver that they are tiring and at risk of falling asleep at the wheel
    2. Active Safety Systems
    Bosch’s active safety systems intervene before accidents occur, helping to reduce serious injuries and fatalities. In 2010 Bosch launched the new, more compact generation 9 ABS for motorcycles – the first anti-lock brake system specifically developed for motorcycles. The base version of the system weighs just over 1.5 pounds, making it the smallest system available.

    Motorcycle ABS includes speed sensors at both wheels that register the vehicle’s speed. If a wheel risks locking during braking, the ABS hydraulic unit controls the pressure applied by the driver and the wheel’s braking force and deceleration. This process preserves the rotation of the wheel and keeps the bike stable, even on varying surfaces, helping the rider achieve the shortest and safest stopping distance.

    3. Passive Safety Systems
    Bosch’s passive safety systems help reduce driver, passenger and pedestrian injuries. The iBolt™ Occupant Classification system is one way Bosch is helping keep passengers safe when accidents occur.

    iBolt™ – Bosch’s weight-sensing iBolt™ provides safe deployment of vehicle airbags through the accurate and reliable classification of occupants, including an empty seat, one-year-old infant, three- and six-year old child, 5th percentile female and 50th percentile male. The system uses an electronic control unit coupled with two to four seat-securing bolts with integrated sensors that help determine the weight of the front-seat passenger. These sensors report the weight classification to the airbag control unit, which adjusts the force of deployment based on the occupant’s weight – with reduced intensity or turned off completely. Bosch’s system meets the Federal Motor Vehicle Safety Standard 208 (FMVSS 208) and supports 5 Star Rating for 2011 U.S. New Car Assessment Program (NCAP).

    This is not the first time Bosch has reached out to show its capability. As a supplier, they do not garner as much attention as OEMs. Read: Bosch touts functional excellence at the Power of Innovation media event. I was invited last Fall to their engineering facilities in Michigan for a press function.

    At the Power of Innovation media event, for example, Bosch, whose name is ubiquitous within the auto industry supplier base, showed the media its technical advancement that will help automakers in their quest to reach the latest proposed federal CAFE mandate of 54.5 MPG by 2025
  2. My first thought is that all this expensive technology could easily be made redundant if everyone were just required to use public transport.

    I mean, when computers do the driving/riding, you might as well...:roll:
  3. A lot of drivers are going to hate the Lane Keeping Support... it'll mean they actually have to use indicators!! :eek:

  4. Adaptive cruise control is one of the best things in the universe. On the subject of cruise control, it amazes me how many cars in Australia don't have it, though. Given how horrible and boring most of the roads are if you're traveling out of the city, they're fantastic and help avoid getting speeding fines, too*.

    *If you set it at or under the limit, that is. The last car I owned overseas would happily let me engage the cruise control at 140MPH.
  5. This stuff is still not yet at the stage where the tech will do the driving for you, but I wonder when the technology reaches that point whether insurance companies will refuse to insure (or increased excess) drivers who chose to drive 'manually' and have the assistive technologies turned off.

    That would be a step backwards, especially for motorcycle riders who, typically, enjoy riding in and of itself, rather than just a means of getting from A to B.
  6. Sounds like within my life time, I'll be able to fall asleep at the wheel of my car without consequence, and all the safetycrats will consider this a good thing.

  7. there will still be consquences, but people won't be held responsible to account for them.
    sorry mate the car did'nt see you.

  8. Driver assist technology is all good so long its not made mandatory and there are ways to switch it off for the competent drivers. its like choose your difficulty in video games:D
  9. I'm in two minds with AI driving aids. Or let me be the devils advocate :)
    .Ban all driver aids, well an all modern technology bar the brakes, tyres and suspension.
    This has to work in conjunction with taking away all the shell, doors and panels. No seat belts or safety aids at all. No radios, dvd's or windscreens. NO BLUETOOTH.
    .Now the occupants of the vehicle are as likely do die as the innocent victims they hit.
    I'm betting my left nut that increases driver awareness 1,000% right there.
    .They will slow down in wet conditions because, Rain hurts at speed.
    .They have nothing to play with or to listen too bar the car to take their attention away from the job at hand.
    .More people would take public transport or ride a bike.
    We're all lacking that final piece of true happiness. That completeness of inner peace.
    And will always be egotistical self absorbed pratts trying to inflate nothing into that magical bit to fill that spot when we have a big stick in our hands...ie in a car.
    So no matter what we will always be more important than the other person on the road therefore causing avoidable accidents and deaths.
    have a nice day.....:)
  10. I will never ride OR drive anything that decides when to brake for me.
  11. I really don't see the computers doing the driving as a bad thing. You can say bye bye to normal reaction times, morons who cut off, and a much improved traffic flow - so much so I'd expect trip times to decrease by up to 10 percent, maybe more. In addition to that, drivers who are already falling asleep at the wheel and trying to balance that with driving now don't have to worry about the hard part. All in all, I see it being much safer for both riders and drivers.

    For some reason in this country we have a fear of the machine doing tasks for us, even though we have greater reliance on them everyday. It seems much thanks to unions that we still have train drivers in our trains.

    One way or another, ultimately it's inevitable.
  12. Cars with almost any of these driver aids bore me to tears which is one of the reasons I'm giving bikes a go. I will acknowledge that ABS is, on the whole, a good thing but most of the rest of it is masking the real problems. Those are poor driver training, legislation and design failing to take into account required brain activity levels and focussing on the wrong causes.

    The technology is already available for self-driving cars. The supporting infrastructure is being built in parts of Europe. Australia is too big for it to be viable at the moment and will be so for decades except for possible trials in some small areas. The mix of controlled and un-controlled cars will be a major impediment but as the average cost and age of the car fleet reduces so will the transition period.

    I spent Sunday teaching newbies how to drive fast on the race track. While it was understandable that most had never pushed their cars too far past the speed limits, it never eases to amaze me how few have ever experienced hard braking. Almost none have ever felt their ABS fire. It is no surprise then that they react wrongly, if at all, when something goes wrong. Emergency braking needs to be a mandatory inclusion in basic driver education just as it is in bike training and licensing.
  13. Banzai, car ABS and the dynamics it imparts to a car are a very poor simile for how it works on a bike. ABS will stop the wheel from locking and it will do that task very well. How it does it though can have unintended consequences on a motorbike. Top level ABS like on the BMW1000RR and ZX10R aren't so prone to these unintended consequences... but anyway, I won't harp on it again, it's a well worn topic on these boards.

    Lilley said: "All in all, I see it being much safer for both riders and drivers." What makes you think these ITS solutions aren't going to be imposed on bikes? And when they can't be made as safe as the automated cocoons, bikes will be made redundant.

    Wasn't it in the movie "minority report" where the hero steps into a fully automated vehicle that slots neatly into a dense traffic stream at break neck speed? Or was that that "5th element"? Anyway, if that's the future, fully automated driving, then there's no place for motorbikes in 50 - 100 years.
  14. yeh it was minority report.

    With respect to that, transport infrastructure was completely overhauled. At the moment I'm a bit exhausted and can't be bothered writing out some consequences and issues of that in Aus, but I'm sure you will figure most of it out.

    By then we will all be getting our thrills with neuroin anyway.
  15. Safer, maybe. Being better off as a result? I doubt it. I have no problem with computers being a fail-safe for when we stuff up. But when we delegate all judgement and use of skills to them, we are making ourselves weaker and less able, more reliant and less self-sufficient, on both a personal and social level. From an evolutionary perspective, it's a case of use it or lose it. Isn't one of the reasons you ride (or enjoying riding) a motorcycle the challenge of it?

    I was thinking of "I, Robot". :p
  16. Given that family history suggests I've got another 20 or maybe 30 if I'm lucky, I'm finding it difficult to care much, selfish bastard that I am. Given how much Western society changes as a whole over such timespans, the loss of the motorcycle may be the least of everyone's worries.
  17. What an ironic future it will be when we can no longer die on the roads, but instead queue up in droves to be euthanised soylent green style.

    Pat, you selfish Pratt! lol

    Tapatalking loud, saying somethin'
  18. I wouldn't ride a motorcycle that will brake instead of me, not allow me to lock up my rear or front wheel, prevent from wheel slides or highsides because it overrides my input. Motorcycling is about rider input and the machine that responds to it. If you **** up, you end up in the dirt. If you do well, you're a good rider.

    If motorcycles didn't give us "oh shit, that was ****ing awesome" we wouldn't be ridin them.
  19. Too late.
  20. The new Golfs etc annoy me. I was looking at getting one as the upgrade to the Jetta. But the new ones the steering takes over as part of the stability control system. So basically, if you have any idea how to drive, your natural instincs actually make things worse for you as the system trys to fix your original error, as you are counteracting it trying to do the same thing.

    That is too far, and if that tech makes it on to bikes, then it is all over.
