Bosch’s Vehicle Motion and Safety Technologies Aid in Reducing Vehicle-Related Injuries, Fatalities

FARMINGTON HILLS, Mich. – According to a recent study , 45 percent of drivers in crash situations do not take full advantage of their vehicle’s braking capabilities. Bosch – a leader in advanced safety systems – has developed a portfolio of crash avoidance technologies that aid in addressing this issue.

“Bosch’s long-range radar technologies, when integrated with other vehicle systems, provide a range of safety features that aim to reduce vehicle-related fatalities,” explains Dr. Kay Stepper, director of marketing, product planning and innovation management, Chassis Systems Control, Bosch North America. Bosch’s radar system enables advanced comfort and safety options such as adaptive cruise control (ACC) and predictive emergency braking (PEB).

Bosch’s PEB technology consists of predictive collision warning (PCW), emergency brake assist (EBA) and automatic emergency braking (AEB). These technologies can warn the driver of a potential collision, determine when the driver is not fully braking, and intervene accordingly. When in an emergency braking situation, the driver may experience the following:

PCW – The driver is warned via a short yet perceivable brake pulse and/or automatic seat belt retraction.
EBA – Upon initial partial braking by the driver, EBA automatically increases the brake pressure to the required level for the given situation.
AEB – In the case of a distracted driver that does not react or brake, AEB initiates automatic emergency braking if a collision is unavoidable.

Vehicle Safety Beyond Braking
To further assist the driver, Bosch utilizes its multi-purpose camera to support lane vision, including lane departure warning (LDW) and lane keeping support (LKS). The LDW function tracks a vehicle’s course within lane markings and road boundaries, providing acoustic or haptic feedback if the vehicle drifts out of the lane. LKS occurs when the vehicle begins drifting out of a lane by correcting the vehicles path with a smooth return to center.

According to a study conducted by the Insurance Institute for Highway Safety (IIHS), forward collision warning with automatic braking (FCW-AB) and LDW have the highest potential to reduce vehicle-related injuries and fatalities. The IIHS predicts FCW-AB could prevent approximately 2.3 million crashes and 7,200 fatalities per year, while LDW is predicted to prevent 480,000 crashes and 10,000 fatalities per year.

Beginning with model year 2011, the National Highway Traffic and Safety Administration (NHTSA) is proposing revisions to the existing rating program, the New Car Assessment Program (NCAP). The new overall vehicle safety score combines star ratings from the front, side and rollover programs. NCAP requires vehicle manufacturers to include vehicle ratings on all automobile’s Monroney labels with a 1- to 5-star graphic display.

“Bosch has technologies available for mass production to help automakers meet NHTSA’s regulations and NCAP guidelines,” said Stepper. “We are working toward making the road a safer place for drivers now, and in years to come.”

Recent developments of driver assistance and vehicle communication systems make it possible to further improve crash avoidance and mitigation capabilities. The next step, according to Bosch, is integrating separate safety features into an interactive system, which Bosch calls Vehicle Motion and Safety (VMS).

“When active and passive safety, driver assistance and vehicle communication systems come together, the result is increased comfort, greater agility and, ultimately, improved safety for consumers,” said Stepper. “With this approach, we are one step closer to our vision of safe, accident-free driving.”
