Abstract

The vehicle behavior control device is designed to control a behavior of a vehicle having steerable front road wheels. The vehicle behavior control device comprises a PCM configured to perform control to reduce a driving force for the vehicle according to a steering speed of the vehicle, wherein the PCM is operable to reduce a change rate during increasing of a reduction amount of the driving force according to the steering speed of the vehicle, to a smaller value, as a steering wheel angle of the vehicle becomes larger.

Claims (7)

1. A vehicle behavior control device for controlling a behavior of a vehicle having steerable front road wheels, an engine or a motor and a steering wheel operated by a driver, the vehicle behavior control device comprising:

a processor; and

a memory storing one or more programs that, when executed by the processor, cause a generated torque control means to perform control, when a steering speed of the steering wheel is greater than a threshold, to reduce a generated torque of the engine or the motor according to the steering speed of the steering wheel,

wherein the generated torque control means is operable to reduce rate of decrease of an amount of the generated torque during decreasing the amount of the generated torque according to the steering speed, as a steering wheel angle of the steering wheel increases.

2. The vehicle behavior control device as recited in claim 1 , wherein the generated torque control means is operable, when the steering wheel angle is increasing, to reduce the generated torque according to the steering speed.

3. The vehicle behavior control device as recited in claim 1 , wherein the generated torque control means is operable to decide a target additional deceleration to be further applied to the vehicle, according to the steering speed, and reduce the generated torque so as to realize the target additional deceleration, and to reduce a change rate during increasing of the target additional deceleration, as the steering wheel angle increases.

4. The vehicle behavior control device as recited in claim 1 , wherein the generated torque control means is operable to control the behavior of the vehicle by using a torque generated from the engine as the generated torque.
