Title
(EN) CONTROL OF A LIMITED SLIP DIFFERENTIAL BASED ON A STEERING ANGLE OF A VEHICLE
(FR) COMMANDE D'UN DIFFÉRENTIEL AUTOBLOQUANT REPOSANT SUR UN ANGLE DE DIRECTION D'UN VÉHICULE
Abstract
(EN)
A limited slip differential (LSD) transfers a torque from an engine to left and right wheels of a vehicle. A current angle of a steering device is determined. Rotational speeds of 5 the left and right driven wheels are also determined. A current wheel slip of is calculated as a difference between the rotational speeds of the left and right wheels. Maximum and minimum allowed wheel slips are calculated as a function of the current steering angle. The LSD is controlled so that the current wheel slip stays in a range between the maximum and minimum allowed wheel slips. To this end, the LSD is loaded if the wheel slip falls outside of the range 0 between the maximum and minimum allowed wheel slips.
(FR)
Un différentiel autobloquant (LSD) transfère un couple d'un moteur à des roues gauche et droite d'un véhicule. Un angle actuel d'un dispositif de direction est déterminé. Des vitesses de rotation des roues menées gauche et droite sont également déterminées. Un patinage de roue actuel est calculé en tant que différence entre les vitesses de rotation des roues gauche et droite. Des patinages de roue autorisés maximum et minimum sont calculés en fonction de l'angle de direction actuel. Le LSD est commandé de sorte que le patinage de roue actuel reste dans une plage comprise entre les patinages de roue autorisés maximum et minimum. À cette fin, le LSD est chargé si le patinage de roue tombe en dehors de la plage 0 entre les patinages de roue maximum et minimum autorisés.
