A vehicle includes a powerplant, such as an engine, configured to power front and rear wheels, and a controller. The controller is programmed to, brake a first of the front wheels and a first of the rear wheels while powering a second of the front wheels and a second of the rear wheels to warm those tires, and subsequently brake the second front wheel and the second rear wheel while powering the first front wheel and the first rear wheel to warm those tires.

A vehicle includes front suspension assemblies; rear suspension assemblies; a left driven wheel and a right driven wheel with first left and right brake assemblies; a left wheel and a right wheel with second left and right brake assemblies; an anti-lock braking system (ABS) module; a drive mode coupler connected between the transmission and the left and right wheels for changing between a 24 and a 44 drive configuration; and a drive mode switch for controlling the drive mode coupler, the ABS module selectively performing brake traction control of at least one wheel based on the position of the drive mode switch. A method for controlling traction of the vehicle includes sensing the drive mode switch position and when the drive mode changes from a 24 position to a 44 position, causing the ABS module to perform brake traction control on at least one wheel.

This driving assist apparatus for a vehicle sets target wheel speed of an inside rear wheel in turning to substantially zero when a state of a center differential apparatus is a locked state in a case where the vehicle is turned in an extremely low speed traveling control. Further, the apparatus sets target wheel speed of each of wheels other than the inside rear wheel in turning such that a mean value of target wheel speeds of front wheels is equal to a mean value of target wheel speeds of rear wheels and the mean value of target wheel speeds of front wheels is equal to target vehicle body speed. Furthermore, the apparatus adjusts driving force and braking force such that wheel speed of each of the wheels becomes equal to the target wheel speed set for each of the wheels.

An articulated work machine includes a frame assembly having a front portion and a rear portion; an articulation joint connecting the front and rear portions and adapted to allow pivotal movement about the articulation joint by the front and rear portions; a plurality of front wheels attached to the front portion and a plurality of rear wheels attached to the rear portion; a brake associated with each of the front wheels and rear wheels; a steering sensor adapted to provide a steering signal from a steering mechanism of the articulated work machine; and a controller adapted to receive the steering signal, and wherein when a braking force is applied to the front and rear wheels when the controller receives the steering signal, the controller produces a signal to modulate the braking force to allow the front portion and rear portion of the machine to articulate without the machine moving forward.

A method for operating a parking brake system includes establishing a parking brake request for a first automated parking brake constructed on a first wheel located on a first side of an axle of a motor vehicle, producing a braking force at the first wheel by activating, in response to the establishing of the parking brake request, the first automated parking brake, and activating a compensation device connecting the first wheel and a second wheel located on a second side of the axle to apply a braking force to the second wheel via the first wheel.

A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.

A vehicle has an engine, an accelerator control, a limited slip differential (LSD) mounted on an axle driven by the engine, and left and right wheels operably connected to the LSD. An accelerator control position is sensed. A speed of the vehicle is optionally sensed. In order to prevent wheel spin, a high load is selectively applied to the LSD when the accelerator control position meets or exceeds a predetermined position threshold. Optionally, application of the high load may depend on the speed of the vehicle being less than a predetermined speed threshold, the accelerator control position concurrently meeting or exceeding the predetermined position threshold. In order to enhance directional stability of the vehicle, a stabilization load is optionally applied when the speed of the vehicle meets or exceeds the predetermined speed threshold.

A disclosed vehicle braking system according to an exemplary embodiment of this disclosure includes a vehicle body having a first wheel and a second wheel, and a braking system having a first brake at the first wheel and a second brake at the second wheel. The braking system is configured to apply a brake torque to each of the first and second wheels. A drivetrain couples the first and second wheels and is configured to transfer torque between the first and second wheels. A controller is configured to detect a failure condition resulting in one of the first and second wheels becoming a non-braked wheel and command the drivetrain to transfer brake torque to the non-braked wheel. A method of braking a vehicle is also disclosed.

A vehicle drive system configured to achieve a required driving force of braking force without changing an orientation of a vehicle in the event of slippage of a wheel. The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.
