ABSTRACT:
In the suspension control apparatus of the present invention, when a lateral acceleration differential value falls outside a lateral acceleration differential value range, a controller calculates a control input for an actuator, based on the lateral acceleration differential value, in preference to a lateral acceleration. Therefore, immediately after the start of rolling of a vehicle and just prior to the end of the rolling when the lateral acceleration differential value falls outside the lateral acceleration differential value range, the control input for the actuator is calculated based on the lateral acceleration differential value. By this arrangement, it is possible to suppress any uncomfortable sensation which is likely to be transmitted to an occupant of the vehicle immediately after the start of rolling and just prior to the end of rolling in a conventional technique, in which the control input for the actuator is calculated by adding the control input varying in proportion to the lateral acceleration and the control input varying in proportion to the lateral acceleration differential value.
