Abstract
A vehicle roll rigidity control device comprises a control unit and an actuator which can adjust an attenuation force installed between the vehicle front wheel and body. The control unit reduces the attenuation force of the actuator and increases the ability of the vehicle to turn around when the vehicle is in a turn transient state. When the sequential steering operation to the left and right is performed, the controller increases the attenuation force of the actuator and increase the roll rigidity of the front wheels.
Claims4
A roll rigidity control device comprising:
- an actuator installed between a vehicle front wheel and body for generating an attenuation force according to a command signal,
- a sensor for detecting a sequential steering operation to the left and right, and
- a microprocessor programmed to:
- output said command signal to said actuator so that, when said vehicle is in a turn transient state, the attenuation force of said actuator is smaller than the attenuation force when said vehicle is moving straight, and
- output said command signal to said actuator such that the attenuation force of said actuator is larger than the attenuation force when said vehicle is in the turn transient state, when said sequential steering operation is detected.
