Motor vehicle`s e.g. motorcycle, rate of yaw estimating system for use in e.g. electronic stability program system, has unit determining rate of yaw and longitudinal and transversal accelerations according to acceleration components

摘要

The system has mono axis accelerometers (ACC1-ACC4) for measuring acceleration components of a motor vehicle such as motorcycle, according to measurement axes (A1-A4) of a horizontal plane of the vehicle. An information processing unit (UTI) is connected to the accelerometers and determines the rate of yaw of the vehicle and longitudinal and transversal accelerations of the vehicle according to the measured acceleration components and from an preprogrammed kinematic model of the vehicle. An independent claim is also included for a method for estimating the rate of yaw of a motor vehicle.
