Brake Design and Safety Rudolf Limpert
Publisher: SAE International

Crash safety is a priority at Subaru. Masuyuki Naruse, right, assembles his combined brake and accelerator pedal with welder Koji Yonemura in Tamana, Japan. On July 27, 2009, NHTSA published a final rule that amended the Federal motor vehicle safety standard for air brake systems by requiring substantial improvements in stopping distance performance on new truck tractors. It is proposed that the alternative of using rubbing thermocouples not be recognized, as temperature readings will differ and an increasing number of motorcycle brake designs will not accommodate their use. This paper summarizes work intended to further characterize and develop rear brake light signals likely to improve driver reaction to hard-braking lead-vehicle events, emphasizing unique and novel approaches not previously studied. They also checked brake performance, vehicle dynamics control and Foresters new standard X Mode system. Book Description Provides a systems approach to designing safer brakes for cars, light trucks, tractor-trailers, and heavy equipment. The pedal's design helps prevent unintended acceleration, Naruse says. Brembo also cares about daily drivers, driving carefully but still needing extreme braking force to feel confident and safe. VMS-DP units are spring applied, hydraulically released safety brakes designed to operate in the most arduous conditions, where reliable operation all year round is expected. This thesis focuses on two practically important issues associated with the development of an electromechanical brake (EMB, Brake-by-wire) and its safety control in early design stage. Safety is not something the Japanese automaker has just begun to incorporate in their cars. Due to extra time needed to design, test, and validate these vehicles, which included two-axle tractors and severe service tractors, the agency allowed four years lead time for these tractors to meet the improved stopping distance requirements. The new 2014 Subaru Forester is one of the safest SUVs on the planet and it starts with Subaru's extremely high safety targets set before the design starts.
