A method of adjusting the angular rolling position of the plane of a motor vehicle wheel, in which the wheel is mounted on a vehicle so that the plane of the wheel can present a static angular position and a safety angular position, the method providing for the plane of the wheel to be maintained in the static angular position when the wheel is rolling and, in case of detection of at least one critical rolling parameter, for the wheel plane to be shifted to a safety angular position for a predetermined time period before the plane of the wheel is returned to the static angular position. A wheel mounting of a motor vehicle in which the method can be implemented is provided.

1. An adjustment method for the angular rolling position of a plane of a motor vehicle wheel, wherein the wheel is mounted on a vehicle in such a way that the plane of said wheel can have a static angular position and a safety angular position, said method comprising maintaining the plane of the wheel in the static angular position during rolling of said wheel and, in the event of detection of at least one critical rolling parameter, shifting the wheel plane in a safety angular position during a predetermined time period before returning said plane of the wheel to the static angular position, and corresponding the at least one critical rolling parameter to the exceeding of a threshold value for a rolling parameter of the vehicle, said parameter being selected from among lateral acceleration, brake pressure, and rotating speed of a steering wheel. 2. The adjustment method according to claim 1, further comprising selecting the angular rolling position from among a pinch angle, a camber angle and a combination of said two angles. 3. The adjustment method according to claim 2, further comprising corresponding the static angular position to at least one of a pinch angle and a camber angle substantially null. 4. The adjustment method according to claim 1, further comprising using a time period which is less than 10 seconds as the predetermined time period, in particular of a magnitude of 5 seconds. 5. The adjustment method according to claim 1, further comprising using a time period of five seconds as the predetermined time period. 6. The adjustment method according to claim 1, further comprising carrying out the shifting of the wheel between its two angular positions by a binary actuator having a state of putting into static angular position and a state of putting into safety angular position. 7. The adjustment method according to claim 6, further comprising corresponding the stable state of the actuator to the safety angular position of the plane of the wheel. 8. The adjustment method according to claim 6, further comprising using a time for placing the wheel in said safety angular position which is of a magnitude of a tenth of a second. 9. The adjustment method according to claim 6, further comprising using a return time of the wheel plane in said static position which is greater than a time for placing in said safety angular position. 10. Wheel mounting of a motor vehicle by means of a wheel holder, said wheel holder being associated with said vehicle by means of at least one pivot in such a way that a plane of a wheel can have a first substantially zero pinch angle and a second non-zero pinch angle, said mounting further comprising a binary actuator for shifting the wheel holder in each of the pinch angles of the wheel plane, said actuator comprising a control device which is connected to a system for determining at least one rolling parameter, and said control device being arranged to adjust the pinch angle by implementation of an adjustment method for an angular rolling position of a plane of the wheel, wherein the wheel is mounted on a vehicle in such a way that the plane of said wheel can have a static angular position and a safety angular position, wherein the plane of the wheel in the static angular position is maintained during rolling of said wheel and, in the event of detection of at least one critical rolling parameter, the wheel plane is shifted into the safety angular position during a predetermined time period before returning said plane of the wheel to the static angular position, and the at least one critical rolling parameter is corresponded to the exceeding of a threshold value for a rolling parameter of the vehicle, said rolling parameter being selected from among lateral acceleration, brake pressure, and rotating speed of a steering wheel. 11. Wheel mounting according to claim 10, wherein the wheel holder is associated with the vehicle by means of a plate carrying a central pivot. 12. Wheel mounting according to claim 11, wherein the binary actuator comprises: a cylinder which is provided between a support and the plate, said cylinder comprising a member for actuating the plate by tilting around the pivot; andopposite the cylinder in relation to pivot, a spring which is mounted loaded between the support and the plate. 13. Wheel mounting according to claim 12, wherein the plate comprises two thrust bearings in contact with the support in respectively a position of tilting. 14. Wheel mounting according to claim 12, wherein the static angular position is obtained through activation of the cylinder, and the spring being preloaded in order to obtain the safety angular position in the event of deactivation of the cylinder.
