Abstract
A method for temporarily preventing automatic gear shifting in a vehicle, comprising the steps of: preventing gear shifting as long as a traction control system indicates that at least one driven wheel is spinning, calculating a vehicle acceleration, calculating a value of a derivative of the acceleration or a value indicative of a difference between the vehicle acceleration and a previously calculated vehicle acceleration, and preventing gear shifting for a predetermined time, if the value is equal or higher than a predetermined value. A system, a computer program, a computer program product and an electronic control unit for performing the method are also disclosed.
