Abstract: A road detection method for a motor vehicle provided with at least one rotary multilayer LIDAR sensor and at least one data processor includes acquiring LIDAR data of the environment of the vehicle. The data for which the angle of the beam with respect to the plane of the vehicle is greater than or equal to zero are eliminated from the acquired LIDAR data. For each LIDAR datum, theoretical coordinates of a point are determined as a function of the angle of the beam with respect to the plane of the vehicle and of the angle of the beam in the plane of the vehicle. The standard deviation between the theoretical coordinates and the coordinates of the LIDAR datum is determined. Then, it is determined that the LIDAR datum forms part of the road if the standard deviation is lower than a predefined threshold.

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.
