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.

System and method for operating vehicle in selected vehicle mode

The present disclosure relates to various computer-implemented methods of line-locking a hydraulic vehicle braking system. A method includes performing a preliminary system check and controlling the distribution of fluid between a hydraulic module and an individual wheel-end brake component when the preliminary check is satisfied. The system continues to monitor predetermined vehicle inputs during activation.

Vehicle line-locking braking system and method

A method for controlling a powertrain of a vehicle is provided for traction control. The method comprises controlling wheel slip to a first amount, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount when a vehicle speed is less than a threshold for a first duration, the second amount based on the driver requested output. In this way, the driver is allowed to modify the wheel slip in a controlled way during specific traction control conditions.

Stuck vehicle with time and pedal related traction control

An anti-lock braking system (ABS) calculates driven wheel speed without any sensors on the driven axle assembly. A powertrain control module (PCM) receives signals from an output shaft speed (OSS) sensor and adds the speed and axle ratio information to a control network bus. Access to the CAN bus is provided to enable calculation of the rear wheel speed based on such information so that ABS may implement anti-lock braking functionality by taking into account such information.

Output shaft speed sensor based anti-lock braking system

A method for controlling a powertrain of a vehicle with wheels during a traction control event is provided. The method comprises adjusting wheel torque in response to an amplitude of a band-pass filtered driven wheel speed and a direction of acceleration of driven wheels.

Detection and control of power induced hop during traction control in a vehicle

A method is provided for controlling a powertrain of a vehicle comprising wheels, and an accelerator pedal actuated by a driver. The method comprises controlling wheel slip to a first amount during a first road condition, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount during a second road condition, the second amount based on the driver requested output, the second road condition having higher friction than the first road condition.
