Method for detecting the direction of travel or for detecting a change in the direction of travel of a motor vehicle having at least two wheel speed sensor arrangements (1a, 1b, 1c, 1d) which each comprise an encoder having an incremental scale and a plurality of scale graduations and a wheel speed sensor (SEa, SEb, SEc, SEd) and are connected to an electronic control unit, wherein, when a scale graduation is detected, the wheel speed sensors each transmit a speed signal to the electronic control unit, and wherein the direction of travel or a change in the direction of travel is determined at least from the order in which the speed signals occur with respect to the individual wheel speed sensor arrangements (1a, 1b, 1c, 1d). The invention also relates to a computer program product for carrying out all of the steps of the method according to the invention. |
