Abstract
In this system for vehicle roll control, a plurality of actuator assemblies are provided, one corresponding to each one of the vehicle wheels and resiliently suspending it from the vehicle body. Each of these actuator assemblies is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding vehicle wheel as results of control signals being supplied to it. A plurality of control means are provided corresponding to the actuator assemblies and serve to supply control signals to them. A vehicle speed detecting means senses the road speed of the vehicle, a steering angle detecting means senses the steering angle of the vehicle, and a lateral acceleration detecting means detects the lateral acceleration of the vehicle body. A means for computing and control predictingly computes the roll angle of the vehicle body from the vehicle speed sensed by the vehicle speed detecting means and the steering angle sensed by the steering angle detecting means, and controls the plurality of actuator assemblies, via the plurality of control means, in accordance with the computed roll angle, so as to reduce the rolling of the vehicle body to keep the vehicle body r…
