Device for detecting a motor vehicle's surroundings has magnetic field sensor elements to detect magnetic fields and transmit signals to trigger a safety mechanism.

摘要

Detection by magnetic fields using magnetic field sensor elements (1) and a signal-processing device for processing the magnetic fields detects a motor vehicle's (2) surroundings and records them in relation to the motor vehicle's movement relative to other fixed and/or moving objects. Magnetic field sensor elements are allocated to the vehicle on its side walls (4), its rear section (6) and/or its front section (8). An Independent claim is also included for a safety device for triggering a safety mechanism during motor vehicle impact by relying on data about seat occupation.
