ENHANCEMENT OF VEHICLE STABILITY BY CONTROLLING THE FRONT BRAKES AND ENGINE TORQUE

摘要

For the progress of vehicle safety, enhancement of active safety performance is as important as crash safety performance.rnIn emergency situations, it is very difficult for an ordinary driver to stabilize the vehicle because steering, braking, and/or other operations in this situation change the vehicle behavior suddenly.rnFrom this point of view, enhancement of vehicle stability is very important for active safety. HONDA has developed an active safety system called VSA (Vehicle Stability Assist) based on expanding the usual active safety system, ABS (Anti-lock Brake System) and TCS (Traction Control System).rnVSA controls front wheel brakes and engine torque to stabilize the vehicle by comparing yaw rate of the vehicle with the reference value calculated from lateral acceleration and vehicle speed, and the driver's intention estimated from steering angle.
