Method for operating a safety system of a motor vehicle in the event of a collision and motor vehicle
First Claim
1. A method of operating a safety system of a motor vehicle in the event of a collision with a collision object, the safety system including a longitudinal restraint system and a transverse restraint system, the method comprising:
- using a plurality of collision sensors to record acceleration of the motor vehicle in sensor data, the sensor data describing directions of the acceleration within a horizontal plane;
determining a first motion value that describes motion of at least one occupant of the motor vehicle along a longitudinal direction of the motor vehicle based on the sensor data;
determining a second motion value that describes motion of the at least one occupant of the motor vehicle along a transverse direction of the motor vehicle based on the sensor data;
determining that a first action threshold has been exceeded based on the first and second motion values;
triggering the longitudinal restraint system and/or the transverse restraint system based on the first action threshold being exceeded;
determining that a second action threshold has been exceeded based on the first and second motion values; and
updating an operating parameter relating to a severity of action of the longitudinal restraint system and/or the transverse restraint system based on the second action threshold being exceeded.

Abstract
A method for the operation of a safety system of a motor vehicle in the event of a collision with a collision object, the acceleration of the motor vehicle being recorded by a plurality of collision sensors of the motor vehicle in various sensor data describing directions within the horizontal plane and being evaluated with regard to the triggering and/or an adaptation of an operating parameter as actions of restraint systems for occupants of the motor vehicle, wherein, of the sensor data, two motion values are determined which describe the motion of at least one occupant, especially all occupants, of the motor vehicle along at least one longitudinal direction and at least one transverse direction of the motor vehicle and which span a two-dimensional decision space, the ranges of action assigned to the actions being defined in the decision space and an action being carried out if the point in the decision space described by the motion values is within the range of action assigned to the action.
