Monitoring system for vehicle e.g. lorry, has acceleration sensor and ultrasonic sensor that are connected with evaluation unit, where evaluation unit generates control signal based on signal comparison of measuring signals of sensors

摘要

The system (1) has an acceleration sensor (S2) and an ultrasonic sensor (S1) that are connected with an evaluation unit, where the acceleration sensor is firmly connected to a vehicle body shell (A). The evaluation unit generates a control signal on the basis of a signal comparison of measuring signals of the sensors. The evaluation unit is connected with another sensor that is formed as switch and the sensors are integrated in a common housing. An alarm unit e.g. siren, is activated based on the value of the control signal. An independent claim is also included for a method for identifying an unauthorized intrusion into a vehicle.
