Abstract
A method and a device for measuring the angular position, between two steering locks, of a steering wheel of a vehicle, includes equipping the vehicle with a main gearing (4, 5) designed, once the vehicle has started, to make it possible to calculate the absolute angular position of the steering wheel from data provided by a first angular sensor (15) associated with this main gearing. According to the invention, the vehicle is additionally equipped with an auxiliary gearing composed of one of the gearwheels (5) of the main gearing, of a third gearwheel (8), and of intermediate elements (6, 7, 9) for sequentially driving the third gearwheel (8) that are able to make it possible, upon starting of the vehicle, to measure the angular position of the third gearwheel (8) via a second angular sensor (16) associated with this gearwheel.
