Title: Behavior control device of vehicle checking occasionally normal operation of longitudinal acc. sensor

Abstract: A behavior control device of a vehicle including a longitudinal acceleration sensor has a judgment system for judging if the longitudinal acceleration sensor is operating normally by comparing an output of the acceleration sensor with a corresponding longitudinal acceleration of the vehicle detected based upon a wheel rotation speed detected by a sensor therefor, excepting at least when the acceleration sensor output is much different from a longitudinal acceleration calculated based upon a wheel drive torque, so that the reliability of the behavior control incorporating the acceleration sensor is ensured, while when the acceleration sensor is not operating normally, the behavior control is modified or suspended.
