Abstract:
A distance sensor for a motor vehicle, comprising:a sensor element for performing one of: transmitting one of microwaves and light, and receiving an echo signal reflected by a target object; a control system including an arrangement for, during travel on a straight road, using an algorithm to ascertain a misalignment angle of the sensor element with respect to a center axis of the motor vehicle from transmitted and received rays, the arrangement correcting a continuing angle measurement in accordance with the misalignment angle; and an arrangement for compensating for a trajectory for a curvature travel along a curve wherein: the control system determines a quality indicator of the trajectory from ascertained misalignment angles of individual trajectories in accordance with an adaptive long-term filter; and the adaptive long-term filter is a noise-optimized linear filter.
