Method and device for determining the size and position of a parking space

Abstract

The present invention relates to a method and a device for determining the size and position of a parking space in relation to the position of a vehicle while the vehicle is driving past the parking space, the parking space extending longitudinally to the traffic lane and transversely to the traffic lane. It is the objective of the present invention to provide an ultrasound-based system for parking space measurement that operates more precisely than the known ultrasound-based systems for parking space measurement, even when passing the parking space at high speed and given high sensing depth of the parking space. Due to the fact that the width of the parking space is determined with the aid of a first ultrasonic sensor having a first sensitivity, and the depth of the parking space is detected with the aid of a second ultrasonic sensor having a second sensitivity, the sensitivity of the first ultrasonic sensor being lower than the sensitivity of the second ultrasonic sensor, it is possible to achieve higher accuracy in the parking space measurement.
