Abstract

Proposed is a device for triggering a restraining system in a vehicle, the device triggering the restraining system as a function of a mass estimate of an impact object. In this context, the device is configured such that it performs mass estimates as a function of at least one pre-crash signal, at least one vehicle datum, the own vehicle speed, and at least one impact signal.

Claims

1. A device for triggering a restraining system in a vehicle, comprising:

an arrangement for triggering the restraining system as a function of a mass estimate of an impact object; and

an arrangement for performing the mass estimate as a function of at least one pre-crash signal, at least one vehicle datum, and at least one signal of an inertial sensory system;

wherein the at least one vehicle datum includes a mass of the vehicle and a stiffness of the vehicle.

2. A device for triggering a restraining system in a vehicle, comprising:

an arrangement for triggering the restraining system as a function of a mass estimate of an impact object; and

an arrangement for performing the mass estimate as a function of at least one pre-crash signal, at least one vehicle datum, and at least one signal of an inertial sensory system;

wherein a stiffness of the impact object is determined from an impact signal and an impact speed.
