Abstract
Aspects of the present invention relate to a method and to a control system for controlling an active suspension of a vehicle, the control system comprising one or more controllers, the control system configured to: determine whether a transient suspension disturbance to the vehicle is from within a cabin of the vehicle; and control a variable force parameter of the active suspension in dependence on whether the transient suspension disturbance is from within the cabin of the vehicle.
Claims18
A control system for controlling an active suspension of a vehicle, the control system comprising one or more controllers, the control system configured to:
- detect or predict a transient suspension disturbance to the vehicle;
- determine whether the transient suspension disturbance to the vehicle is from within a cabin of the vehicle;
- and
- control a variable force parameter of the active suspension at one or more axles in dependence on (i) whether the transient suspension disturbance is from within the cabin of the vehicle and (ii) a detected roll angle or pitch angle, the variable force parameter controlling an extent to which the active suspension prevents cabin/body movement of the vehicle.
A method of controlling an active suspension of a vehicle, the method comprising:
- detecting or predicting a transient suspension disturbance to the vehicle;
- determining whether the transient suspension disturbance to the vehicle is from within a cabin of the vehicle;
- and
- controlling a variable force parameter of the active suspension at one or more axles in dependence on (i) whether the transient suspension disturbance is from within the cabin of the vehicle and (ii) a detected roll angle or pitch angle, the variable force parameter controlling an extent to which the active suspension prevents cabin/body movement of the vehicle.
A method of controlling an active suspension of a vehicle, the method comprising:
- detecting or predicting a transient suspension disturbance to the vehicle;
- identifying a source of the transient suspension disturbance to the vehicle as being either inside a cabin of the vehicle or outside the cabin of the vehicle;
- and
- controlling the active suspension at one or more axles differently when the source of the transient suspension disturbance to the vehicle is identified as being from within the inside of the cabin rather than being from outside the cabin of the vehicle based on a detected roll angle or pitch angle of the vehicle.
