Abstract: A method for evaluating an height of an object in the surrounding environment of a vehicle, using ultrasonic signals acquired by an ultrasonic sensor mounted on the vehicle. In a measurement cycle, a first ultrasonic signal is acquired as an edge reflection or as a directly traveling echo of an object. An expectation window is calculated for an associated interior-corner reflection. A second ultrasonic signal acquired in the expectation window is recognized as an interior-corner reflection associated with the first ultrasonic signal. The first and second ultrasonic signals are combined to form a signal group. A significance is determined for each ultrasonic signal. The signal group is assigned to a first or second echo group. The rates of the assignment to the first and to the second echo group are determined over a number of measurement cycles. An evaluation of the height is based on the first and second rates.
