ABSTRACT:
The apparatus for measuring a distance to an object with ultrasound includes a number of ultrasonic transducers (1 to 10) arranged in a motor vehicle for propagation of ultrasonic pulses and a controller (13) including a device for controlling the ultrasonic transducers to sequentially propagate ultrasonic pulses from the respective ultrasonic transducers (1 to 10) and a device to simultaneously propagate ultrasonic pulses from each ultrasonic transducer so that the ultrasonic pulses from respective ultrasonic transducers are superimposed on each other when no obstacle is detected during sequentially propagating ultrasonic pulses, or according to a vehicle speed. Reflected ultrasonic pulses from an object near the vehicle are received by at least one of the ultrasonic transducers (1 to 10) after propagation of the ultrasonic pulses. An evaluation device evaluates the reflected ultrasonic pulses from the object and preferably activates warning devices for the driver as needed.
