Abstract

The present invention relates to a safety system for occupants of a vehicle 1, having means such as, in particular, acceleration sensors and/or pressure sensors for sensing a side crash. The safety system 20 also includes means for detecting the lateral velocity vQ of vehicle 1. The control of the restraining devices of the safety system is able to be influenced by the detected lateral velocity. A method for the control of a safety system is also described.

Claims

1-7. -7. (canceled)

8. A safety system for occupants of a vehicle, comprising:

a side crash sensor including at least one of an acceleration sensor and a pressure sensor, the side crash sensor configured to sense a side crash; and

a detector to detect a lateral velocity of the vehicle, control of restraining devices of the safety system being influenced by the detected lateral velocity.

9. The safety system as recited in claim 8, for comprising:

a comparator configured to compare the detected lateral velocity to a specifiable limiting value of the lateral velocity.

10. The safety system as recited in claim 8, further comprising:

a storage device which stores limiting values of the lateral velocity as a function of limiting values of the side crash sensor.

11. A method for controlling a safety system for occupants of a vehicle, comprising:

sensing a side crash;

acquiring vehicle-dynamics quantities of the vehicle including a lateral velocity of the vehicle; and

controlling the safety system as a function of the side-crash sensing and the detected lateral velocity.

12. The method as recited in claim 11, wherein in response to a high measured value of the side-crash sensing and a low measured value of the lateral velocity, restraining devices of the safety system are prepared for triggering or are triggered.

13. The method as recited in claim 11, wherein in response to a high measured value of the side-crash sensing and a low measured value of the lateral velocity, a triggering algorithm of the safety system is parameterized in a direction of a higher triggering sensitivity.

14. The method as recited in claim 11, further comprising:

ascertaining a float angle of the vehicle from measured values of the vehicle-dynamics quantity, the float angle being taken into account in the control of the safety system.
