Abstract: A module includes a device for transmitting a first setpoint state vector as the input to a closed control loop of a path control device such that the vehicle travelling in a first lane moves to a second lane, the path being modelled by a first Bezier curve, and a device for modelling, using a second Bezier curve, a path for returning the vehicle to the middle of the first lane when the lane change is aborted. The second Bezier curve is parameterized using the lateral position and the lateral speed of the lane change path for changing from the first lane to the second lane at the time when the lane change is aborted.

The method includes, for each selected acceleration phase: calculating a mean value of a differential force equal to a value of the traction loads of the unit from which there are subtracted the value of the acceleration resultant force and the value of the sum of the resistive loads experienced by the vehicle, calculating a statistical value based on the calculated mean values of the differential force, and comparing the statistical value against a vehicle overweight threshold value. The vehicle is in an overweight state if the statistical value is higher than the threshold value.
