Abstract
A suspension control system includes: variable damping force dampers provided between a vehicle body and each wheel; a roll rate output unit configured to determine if a steering angle speed based on a steering angle is equal to or greater than a prescribed determination value, to output a roll rate detected by a roll rate sensor if the steering angle speed is equal to or greater than the determination value, and to output zero if the steering angle speed is less than the determination value; a pitch moment computation unit configured to compute a target pitch moment of the vehicle body based on an output of the roll rate output unit; and a damping force computation unit configured to compute a target damping force of each damper based on the target pitch moment.

A suspension control system for a vehicle having wheels, comprising:
- variable damping force dampers provided between a vehicle body and each wheel;
- a steering angle sensor configured to detect a steering angle;
- a roll rate sensor configured to detect a roll rate;
- a roll rate output unit configured to determine if a steering angle speed based on the steering angle is equal to or greater than a prescribed determination value, to output the roll rate detected by the roll rate sensor if the steering angle speed is equal to or greater than the determination value, and to output zero if the steering angle speed is less than the determination value;
- a pitch moment computation unit configured to compute a target pitch moment of the vehicle body based on an output of the roll rate output unit;
- and
- a damping force computation unit configured to compute a target damping force of each damper based on the target pitch moment.
