Environment detection device e.g. for moving motor vehicle, has transmitting device arranged adjacent to first discrete transmitter for radiating ultrasound waves

摘要

A device for detecting the environment surrounding a moving object, especially a motor vehicle has a transmitting device for radiating ultrasound waves and receivers (4) for detection of ultrasound waves from the transmitter and those ultrasound waves reflected from an obstacle. The transmitting device (3) is arranged adjacent to a first discrete transmitter (6) for radiating ultrasound waves at a first transmitting frequency (F1), and a second discrete transmitter (7) for radiating ultrasound waves at a second frequency (F2) different from the first frequency (F1). An independent claim is included for a method for environmental detection for a moving object, such as a motor vehicle.
