Abstract

A method for alleviating the consequences of a collision of a vehicle, having a front axle and/or a rear axle with at least one roll stabilization device with which torques can be applied in the region of the front axle and/or the rear axle for the purpose of roll stabilization. In order to alleviate the consequences of collisions of vehicles, in the event of a collision protective torques are generated using the roll stabilization devices.

Claims

1. A method for alleviating the consequences of a collision of a vehicle having a front axle and a rear axle and at least one roll stabilization device with which torques can be applied in the region of the front axle and the rear axle for the purpose of roll stabilization,

wherein, in the event of a collision, protective torques are generated by the at least one roll stabilization device to alleviate the consequences of the collision, and

wherein, in the event of the collision, alternating protective torques are generated in the region of the front axle and the rear axle using the roll stabilization devices, which protective torques have directions of action which are opposed with respect to a rolling axle and which counteract torsion of the vehicle owing to the collision.

2. The method of claim 1 further comprising sensing an imminent collision using sensing devices prior to initiating the protective torques.

3. The method of claim 1 further comprising sensing of the collision either at the time of the collision or shortly after the collision using sensing devices and initiating the protective torques following the sensing.

4. The method of claim 1, wherein the protective torques are each generated by activating a drive unit, which causes rotation of an anti-roll bar, which causes translation of a strut that is associated with one of the front axle and the rear axle.

5. A system for alleviating consequences of a collision of a vehicle, which system comprises a front axle and a rear axle each having roll stabilization devices, with which opposing torques which counteract a rolling torque can be applied in a region of the front axle and the rear axle for the purpose of roll stabilization,

wherein, in the event of a collision, the roll stabilization devices are configured to generate protective torques which alleviate the consequences of the collision, and the roll stabilization devices are configured to generate alternating protective torques in the region of the front axle and the rear axle using the roll stabilization devices, which protective torques have directions of action which are opposed with respect to a rolling axle and which counteract torsion of the vehicle owing to the collision.

6. A computer program product having a program code for activating the roll stabilization devices of claim 5 to alleviate the consequences of the collision.

7. A control unit for controlling roll stabilization having the computer program product of claim 6.

8. A motor vehicle having roll stabilization and having the control unit as claimed in claim 7.

9. The system of claim 5, further comprising a drive unit for rotating an anti-roll bar that is connected to a strut that is associated with one of the front axle and the rear axle, wherein activation of the drive unit causes rotation of the anti-roll bar, which causes translation of the strut, which generates the protective torque.
