Abstract (en)
The method involves calculating a compensation coefficient during detection of a fixed obstacle causing a change of state of an output signal of a rear sensor and a delay output signal of a front sensor, when slopes of the change of state of the signals have same sign and absolute values of the slopes are greater than a determined threshold value. The calculated coefficient is added to output measurement signal of the front sensor.
