Control system for adjustable damping force damper

A control system for an adjustable damping force damper, comprising:

• a damper provided to a suspension apparatus of a vehicle;
• a lateral acceleration sensor provided on a predetermined position of a vehicle body and detecting a lateral acceleration of the vehicle;
• a yaw rate sensor detecting a yaw rate;
• and
• a control unit which calculates a lateral acceleration at a position of the suspension apparatus in accordance with the lateral acceleration detected by the lateral acceleration sensor and the yaw rate detected by the yaw rate sensor, and determines a damping force of the damper in accordance with the thus calculated lateral acceleration.

A control method for controlling an adjustable damping force of a damper provided to a suspension apparatus of a vehicle, comprising the steps of:

• detecting a lateral acceleration of the vehicle at a gravity point of the vehicle;
• detecting a yaw rate of the vehicle;
• and
• calculating a first target damping force based on the detected lateral acceleration at the gravity point of the vehicle;
• estimating a lateral acceleration at an axel position in accordance with the detected yaw rate;
• calculating a second target damping force based on the estimated lateral acceleration at the axel position;
• comparing an absolute value of the first target damping force with an absolute value of the second target damping force;
• and
• setting a target controlling damping force in accordance with the first or second target damping force which has a larger absolute value.
