Abstract
A driving assistance method for a motor vehicle (1) when approaching a speed bump comprises, according to the invention: detecting and tracking at least one other moving vehicle (41) in front of the motor vehicle (1) based on processing images captured by a camera (10) on board the motor vehicle (1); establishing a temporal profile of the estimated distance between the motor vehicle (1) and the at least one detected and followed other moving vehicle (41); detecting an anomaly area in the temporal profile; and estimating a distance dbump between the motor vehicle (1) and a speed bump (3) on the basis of the estimated distance between the motor vehicle (1) and the at least one other vehicle (41) at a time separate from the times corresponding to the detected anomaly area.
