Abstract
A method for operating a motor vehicle with a chassis having a suspension device and a damping device according to which, for greater safety, the suspension and/or damping device is stiffened and/or blocked at least for individual wheels when an acceleration signal is applied. The invention also relates to a device with a construction for carrying out the method. The damping device is configured by a hydraulic shock-absorber for each wheel of the motor and at least one shock-absorber can be hydraulically stiffened or blocked via electronically controlled valves. The valve can be controlled by means of a control device connected to at least one acceleration sensor.
Claims9
A method of operating a motor vehicle having a plurality of wheels and each wheel is cooperative with a respective shock absorber, including:
- sensing an impact condition representing a collision between said vehicle and a physical object and generating a signal representing said impact condition;
- and
- locking at least one shock absorber only on a side of said vehicle opposite a side impacted in the event of the collision of said vehicle responsive to said signal.
A system for operating a vehicle having at least one shock absorber cooperable with a wheel thereof, comprising:
- means for sensing an impact condition representing a collision between said vehicle and a physical object, operable to generate a signal representing said impact condition;
- and
- means responsive to said signal for locking said at least one shock absorber,
- wherein only at least one shock absorber on a side of the vehicle opposite said collision is locked during said impact condition.
