Device for calculation estimated vehicle acceleration and speed.

摘要

A device for calculating estimated vehicle acceleration and speed for use in eatimating vehicle speed Vv and vehicle acceleration Av, such that a subservient acceleration Az based on the wheel speed is used when As>Az during acceleration or when As<Az during deceleration, while the substitute acceleration As based on the gravity-type accelerometer is used in place of Az when As<Az during acceleration or when As>Az during deceleration. <IMAGE>
