The output with the push-rod in IDLE position is 0x40 (so 64 decimal) and when fully pressed the value is 0xC0 (192 decimal). Jon has figured this out (it’s not only Byte 3). It looks like Byte 3 of message 0x38E represents the push rod position. While pushing in the rod on the YAW CAN-BUS I did get some consistent results. On the YAW CAN-BUS only two messages are being send, 0x38E and 0x38F. Additionally it can be used to overrule any throttle input. You can immediately (gradually) increase regenerative braking and don’t have to wait for pressure buildup. The advantage of using a CAN input based on stroke is that it is faster. That signal is then used in the vehicle control unit (VCU) to also activate regenerative braking. #IBOOSTER MX DRIVER#Traditionally a pressure transducer is used to know the driver hits the brakes. Bosch has more than 3,000 engineers around the world working to make automated driving a reality.ĮXPERIENCE BOSCH AT NAIAS 2018 in Detroit, Michigan, USA: At NAIAS 2018, Bosch is presenting automated, connected and electrified technologies with a focus on how vehicle electrification is becoming more desired and accessible.īOSCH BOOTH: Monday to Thursday, January 15-18, 2017, on Level Three, Room 330A, Cobo Center.This can be useful to improve regenerative braking in a conversion. Bosch has this expertise, and manufactures most of the key components itself – including radar, video, and ultrasonic sensors, brake control systems, electrical power-steering units, display instruments, and connectivity solutions inside and outside the vehicle. Making automated driving a reality calls for profound understanding of all vehicle systems. The system, which enables either a driver or auto pilot system to make a safe stop in the rare case of a single failure, is a key requirement on the path to fully automated driving. At NAIAS 2017, Bosch introduced its Electric Power Steering (EPS) system with fail-operational function. Redundant steering is also a key technology for automated driving and Bosch is leading in this area. Bosch was also honored with an eMove360° Award in the category of Automated Driving for the redundant braking technology. Even if a failure occurs in the brake system, either actuator (iBooster or ESC) is able to avoid wheel lock-up by modulating the brake pressure, which maintains the ability to steer during deceleration.īosch’s redundant brake system for automated driving was named a finalist for the 2018 Automotive News PACE (Premier Automotive Suppliers’ Contributions to Excellence) Award, which is acknowledged globally as a prestigious industry benchmark for automotive supplier innovation. The redundant brake system is comprised of two actuators that are each able to decelerate the vehicle independent of the driver applying the brake pedal. A conventional brake system today comprises two actuators: a vacuum brake booster and ESC unit. The technological breakthrough of redundant braking was achieved by modifying one system element the vacuum brake booster is replaced by an intelligent electro-mechanical booster, the iBooster. Both are independently capable of performing braking functions for the vehicle in the rare case of a single failure. For SAE levels 4 and 5, the redundancy becomes even more critical as the time span increases without the driver in the loop.īosch’s solution for a fail-degraded brake system (steering system and EE architecture) is the combination of its electromechanical brake booster iBooster and ESC (Electronic Stability Control), also known as ESP® (electronic stability program), systems. Redundant functions ensure that all safety-critical functions continue during this time span, even in the rare case of a failure in the system. #IBOOSTER MX DRIVERS#Drivers must still remain present, but will need a certain amount of time to realize that an intervention is necessary. For these vehicles, a human driver is still necessary, but safety-critical functions may be completely shifted to the vehicle under certain traffic or environmental conditions. SAE level 3 (conditional automation) vehicles will begin to hit the market as soon as 2018. “The importance of redundancy for the rollout of automated driving goes beyond just the technological function as it ultimately will build confidence in consumers as they understand these systems are designed with deep levels of complexity to handle a variety of situations,” said Mike Mansuetti, president of Bosch in North America. At the 2018 North American International Auto Show, the leading global supplier of technology and services will showcase its braking solutions, including redundant braking for automated driving. Bosch is actively developing and bringing to market redundant braking solutions to support all levels of automation as defined by SAE.
