Abstract: There is provided a vehicle behavior control device capable of improving responsivity of a vehicle behavior and a linear feeling with respect to a steering wheel operation without causing a driver to experience a strong feeling of intervention of the control and, at the same time, capable of controlling behavior of a vehicle in such a manner as to also improve stability of the vehicle attitude and riding comfort. In a vehicle behavior control device applied to a vehicle having steerable front road wheels, the vehicle behavior control device includes a PCM which acquires a steering speed of the vehicle, and generates a deceleration jerk which is a rearward jerk in a longitudinal direction of the vehicle when the steering speed becomes equal to or greater than a given threshold TS1 which is greater than zero.

Abstract: There is provided a vehicle behavior control device capable of improving responsivity of a vehicle behavior and a linear feeling with respect to a steering wheel operation without causing a driver to experience a strong feeling of intervention of the control and, at the same time, capable of controlling behavior of a vehicle in such a manner as to also improve stability of the vehicle attitude and riding comfort. In a vehicle behavior control device applied to a vehicle 1 having steerable front road wheels 2, the vehicle behavior control device includes a PCM 14 which acquires a steering speed of the vehicle, and increases a vertical load on the front road wheels when the steering speed becomes equal to or greater than a given threshold TS1 which is greater than zero.

In a vehicle behavior control device applied to a vehicle 1 having steerable front road wheels 2, the vehicle behavior control device includes a PCM 14 which acquires a steering speed of the vehicle, and increases a pitch angle in such a direction that a front portion of the vehicle dips when the steering speed becomes equal to or greater than a given threshold TS1 which is greater than zero.

Abstract: There is provided a vehicle behavior control device capable of improving responsivity of a vehicle behavior and a linear feeling with respect to a steering wheel operation without causing a driver to experience a strong feeling of intervention of the control, and capable of controlling behavior in such a manner as to improve stability of the vehicle attitude and riding comfort. The device includes a PCM which acquires a steering speed relating to a jerk in a width direction of the vehicle, sets a torque reduction flag, indicative of whether or not a condition for allowing reduction of an output torque of an engine is satisfied, based on the steering speed, and starts to reduce a torque when the torque reduction flag is set to True indicative of a state in which the condition for allowing reduction of the torque is satisfied.
