Device for assisting orientation of wheels of vehicle

The invention relates to a device for assisting the driving of a motor vehicle (1), wherein it includes a processing unit (3) configured to calculate the angular position (41) of at least one wheel (5) of the vehicle (1) relative to a reference angular position and to generate a light signal (8) representative of the angular position of said at least one wheel (5) relative to the reference position (40). Also disclosed is a method for assisting the driving of a motor vehicle (1) equipped with such a device. The method includes a step of definition of the reference axis (4) within the processing unit (3), a step of definition of the reference position (40) within the processing unit (3), a step of calculation within the processing unit (3) of the angular position of at least one wheel (5) of the vehicle (1) relative to the reference position (40), and a step of generation, inside the cab of the vehicle (1), of a light signal representative of the angular position of the at least one wheel (5) relative to the r
