A method of controlling a mobile machine having a set of ground engaging elements includes receiving an image of terrain proximate the mobile machine, detecting a contour of the terrain, determining a projected path of the set of ground engaging elements based on the detected contour of the terrain, and controlling a display device to display the image with an overlay representing the projected path of the ground engaging elements.

A vehicle includes a system and method of modeling and controlling a traction of a wheel of the vehicle. The system includes an observer, a predictive controller and an online solver. The observer receives a dynamic model parameter of the wheel and determines an estimate of a wheel velocity and an uncertainty in the wheel velocity using a non-linear model of the wheel. The predictive controller determines an average gain and differential gain from the estimate of the wheel velocity and the uncertainty in the wheel velocity. The online solver calculates a motor torque and a wheel brake torque for increasing the traction of the wheel with a road based on the average gain and the differential gain. The motor torque and the wheel brake torque are applied at the vehicle.

A control system of a hybrid vehicle, in which a driving power source for travel includes an engine that is started by cranking, a motor that can control a torque, and a clutch that is coupled with the motor and in which a transmission torque capacity continuously changes depending on a change of a control amount is configured to estimate a torque of the clutch based on the torque that the motor outputs, and change rates of the rotational speed of the motor and the clutch caused by changing the control amount, when the torque that the motor outputs is transmitted by the clutch that is in a slip state by changing the control amount.

A method of providing automated application of turn radius reduction in a driver assist mode may include receiving steering wheel angle and wheel speed information to determine a target wheel slip during a turn. The method may further include comparing the target wheel slip to a current wheel slip to determine a slip error, and applying braking torque to an inside wheel based on the slip error to reduce the turn radius.

A drive switching mechanism of a utility vehicle includes: a two-wheel drive and four-wheel drive switching device that switches between two-wheel drive and four-wheel drive of the utility vehicle; and a control unit that controls the drive switching mechanism. The two-wheel drive and four-wheel drive switching device switches between two-wheel drive and four-wheel drive by using a first clutch. The control unit permits the two-wheel drive and four-wheel drive switching device to switch from two-wheel drive to four-wheel drive when a rotation difference of the first clutch becomes equal to or smaller than a predetermined value.

A vehicle control device for a hybrid vehicle includes: an engine and an electric motor; a transaxle including a power transmission path connecting the engine and the electric motor with a driving wheel; a temperature detection unit configured to detect a temperature of the transaxle; and a control unit configured to switch between a series operation mode in which the electric motor is driven for traveling by electric power generated by rotation of the engine and a parallel operation mode in which the engine and the electric motor are driven for traveling. When the temperature of the transaxle is equal to or higher than a first predetermined temperature, the control unit performs a first control of giving priority to the traveling in the parallel operation mode.

An electric-axle device for a commercial vehicle that can minimize the frequency of using a main brake when braking, may include a first clutch device disposed between a motor and a differential casing to transmit or block power, a second clutch device disposed between the differential casing and a disc, an electromagnetic brake applying a braking force to the disc, and that can increase a coasting distance and improve energy efficiency and durability of the motor by disengaging the first clutch device and the second clutch device such that kinetic energy, which is transmitted to the motor from an axle shaft, is blocked as if a neutral gear of a transmission is engaged, when the vehicle coasts.
