Abstract
Methods and apparatus are disclosed for adjusting the front to rear ratio of roll damping and/or roll stiffness in a vehicle based on vehicle yaw rate and/or the rate of change of steering wheel angle. Also disclosed are methods and apparatus for dynamically adjusting one or more suspension system control parameters based on one or more of steering wheel angle, rate of change of steering wheel angle and yaw rate.

A method for controlling a controllable suspension system of a vehicle having a front axle and a rear axle, the method comprising:
- determining a desired yaw rate of the vehicle;
- measuring an actual yaw rate of the vehicle;
- comparing the desired yaw rate and the measured yaw rate;
- upon determining that the desired yaw rate exceeds the measured yaw rate, adjusting the suspension system to increase an effective roll parameter of the rear axle relative to an effective roll parameter of the front axle.
A method for controlling a controllable suspension system of a vehicle having a front axle and a rear axle, the method comprising:
- determining a desired yaw rate of the vehicle;
- measuring an actual yaw rate of the vehicle;
- comparing the desired yaw rate and the measured yaw rate;
- upon determining that the measured yaw rate exceeds the desired yaw rate, adjusting the suspension system to increase an effective roll parameter of the front axle relative to a roll parameter of the rear axle.
A method of controlling an actuator of an active suspension system of a vehicle, the method comprising:
- based at least in part on a measured yaw rate of the vehicle, determining a command for the actuator;
- outputting the command to the actuator;
- and
- in response to the actuator receiving the command, producing a force with the actuator of the active suspension system.
