Vehicle detection system

Abstract

A vehicle detection system for monitoring stationary and moving vehicles is disclosed. The vehicle detection system includes a housing and a first sensor and a second sensor each configured to detect the moving vehicles. A control unit, and a first energy store as well as a second energy store configured to supply the vehicle detection system with electrical energy independently of one another are also provided. The control unit is designed in such a way that the first sensor is permanently switched on during operation of the vehicle detection system and the second sensor is only switched on for a predetermined time when the first sensor has detected a vehicle. The control unit is designed in such a way that, when the voltage of the first energy store falls below a first predetermined voltage, the vehicle detection system is supplied with electrical energy by the second energy store.
