  • Patent number: 11746871
    Abstract: A method for mitigating torque steer in a vehicle having a steering axle with a limited slip differential and a pair of output members. The limited slip differential includes a pair of differential outputs and a clutch. The method includes: operating the limited slip differential with the clutch in the first condition; determining that the vehicle is in a state in which a torque steer condition is occurring or is likely to occur; and operating the clutch to reduce a torque differential between the differential outputs to mitigate the torque steer condition. A vehicle with a steering axle and a controller that is configured to operate a clutch in the steering axle to attenuate torque steer is also provided.
    Type: Grant

  • Patent number: 11407308
    Abstract: A system includes a differential, sensors, and a controller. The differential is operable in a first differential mode in which a first shaft and a second shaft are allowed to rotate at different speeds, and a second differential mode in which the differential inhibits relative rotation between the first and second shafts. The sensors are configured to measure vehicle operating conditions. The controller is in communication with the sensors and the differential. The controller, when the vehicle mode is selected, is configured to determine if an intended path of the vehicle is straight, determine if a vehicle speed is less than a predetermined vehicle speed, and operate the differential in the second differential mode for a predetermined time period in response to the controller determining that the intended path of the vehicle is straight and the vehicle speed is less than the predetermined vehicle speed.
