A vehicle behavior control apparatus is provided which is designed to estimate the state of behavior of a vehicle body and to apply the brakes to wheels for suppressing an unwanted change in behavior of the vehicle body. The apparatus determines a lateral momentum of the vehicle body during traveling to estimate the state of behavior of the vehicle body based on the speeds of the wheels and calculates a target braking effort to be produced by each of the brake actuators based on the state of behavior of the vehicle.

Apparatus for controlling behavior of vehicle using brakes

In the present invention, when the wheel speeds of drive wheels are reduced by an engine brake, there are executed drive wheel control for adjusting the braking forces applied to the drive wheels by the engine brake, and driven wheel control for reducing the wheel speeds of driven wheels by an brake actuator. Drive wheel control raises lateral resistant force of the drive wheels by increasing an engine output torque, and driven wheel control brakes the driven wheels by the brake actuator such as a hydraulic brake. As a result, sufficient deceleration of a vehicle can be obtained while retaining the stability of the vehicle.
