Abstract
An effective vehicle attitude control method in which the abrupt change of the vehicle attitude due to the acceleration slip control can be quickly controlled. When the slippage of a drive wheel is determined to be greater than a predetermined value, the drive force of the drive wheel is controlled and, at the same time, the suspension characteristic is altered to a harder state. For preferentially keeping maneuverability and riding comfort, the altered suspension characteristic may be restored to the original state when a preset time period has passed.
Claims10
A method for controlling a suspension characteristic of a vehicle having at least one drive wheel, a braking system and suspensions associated with wheels including said one drive wheel, said method comprising the steps of:
- detecting a slippage of said one drive wheel of the vehicle;
- determining whether or not the detected slippage is greater than a reference value;
- controlling a drive force of the drive wheel by means of said braking system when the slippage is determined to be greater than the reference value;
- and
- altering an original state suspension characteristic of at least said drive wheel to a harder state when the slippage is determined to be greater than the reference value.
