Abstract

An environment monitoring system for a vehicle includes at least two distance sensors for detecting distance by measuring the propagation time of detection signals. The distance sensors are each designed as a transmitting unit and receiving unit for the detection signals and, in a direct operating mode, emit detection signals, receive reflected components of the detection signals emitted by the distance sensors; and emit active measurement signals according thereto. The system also includes a control device that receives the measurement signals of the distance sensors and determines the object distance of a detected object. At least one distance sensor additionally can be operated in an indirect operating mode to detect a detection signal emitted by another distance sensor and reflected by the object and to generate an indirect measurement signal.
