Abstract
A system and method for determining the distance between an object and a device of varying location, in which a first or second sensor arranged on the device emits a signal which is reflected by the object. The reflected signal is received by the sensor transmitting the signal and by the respective other sensor, and an evaluation device determines the propagation times between the transmission of the signal and the reception of the signal for each sensor and determines therefrom all the possible positions of the objects relative to the device of varying location referred to the sensor. The distance from the motor vehicle being determined from the corresponding positions of the measurements. A highly accurate result of the distance measurement is permitted in conjunction with a minimum evaluation time, the evaluation device determines corresponding positions from the measured data in a first, very accurate evaluation method and subsequently determines further corresponding positions on the remaining unverified measured data in a second, less accurate evaluation method.
