摘要：
A device for evaluating the transverse acceleration of a motor vehicle measures the rotational speeds of two wheels of the vehicle, estimates the transverse acceleration of the vehicle from these speeds, and calculates, as a function of vehicle operating parameters, particularly of the rotational speeds of the wheels and of the transmission ratio engaged, a Boolean slip variable which is negative if the transverse estimated acceleration is relevant for detecting a bend, and which is positive if the reverse is true.
