A lane departure prevention system includes a controller configured to control a braking force of vehicle wheels such that a lane departure prevention yaw moment is applied to a vehicle. The controller determines whether there is a likelihood that the vehicle enters a spinning state based on at least one of a difference between an actual yaw rate and a normative yaw rate of the vehicle calculated based on a steering angle, a vehicle speed, and the lane departure prevention yaw moment, and a degree of braking slip of a turning inside wheel when the lane departure prevention yaw moment is a yaw moment for preventing departure of the vehicle from a lane to a turning outside, and applies a spin prevention yaw moment to the vehicle when it is determined that there is a likelihood that the vehicle will enter the spinning state.

A drive unit for a hybrid motor vehicle comprises an input shaft connectable to an internal combustion engine, a first output shaft connectable to a first wheel, a second output shaft connectable to a second wheel, and a distribution unit. The distribution unit is configured to generate different torques at the first and the second output shafts, the distribution unit acting between the input shaft and the output shafts. The distribution unit comprises a transmission device and first and second generators that are configured to be controlled independently of one another for torque distribution. The first generator is operatively connected to the first output shaft and the second generator is operatively connected to the second output shaft.

According to the present disclosure, a system for providing steering control in a dual path machine includes a propulsion controller operatively connected to plants of the machine for driving ground contacting elements, the propulsion controller being configured to control steering of the dual path machine through drive signals sent to the plants, and a brake controller operatively connected to left and right brakes of the machine, the brake controller being configured to control steering of the machine by providing differential brake pressures to the left and right brakes. The system of the present disclosure provides redundant steering control by receiving an input signal at the brake controller with an indication of steering position, receiving an input signal at the brake controller with an indication of brake position, and providing a differential brake pressure to brakes of the dual path machine based on the steering input signal and brake input signal.

A method of steering a vehicle having a front axle steering mechanism and, in particular, a rear axle steering mechanism. It is proposed that interventions are carried out at the rear axle to maintain the vehicle on course, at the same time, interventions are carried out at the front axle steering mechanism to avoid a restoring self-alignment of the front wheels.

An electromechanical machine that uses electrical power to provide electromechanically-balanced motive torque to one or more mechanical loads, or that uses electromechanically-balanced mechanical power from one or more sources of motive torque to supply electrical power to one or more loads, while seamlessly reconciling the speed and torque differences between such loads-and-sources by use of speed-torque modules and a control means.

A vehicle and method for controlling the same are provided. The vehicle includes a speed detector that detects driving speed of the vehicle, a detection sensor that obtains information regarding at least one of a position and a speed of an object around the vehicle, and a yaw rate detector that detects a speed at which a rotation angle of the vehicle's frame is changed while the vehicle is driven. A controller then determines a yaw rate required for the vehicle to steer to avoid the object, applies partial braking on an inner wheel of the vehicle based on the determined yaw rate, and applies partial braking on an outer wheel of the vehicle to reduce a beta value of the vehicle obtained during the steering-based avoidance when the beta value exceeds a predetermined value.

A control apparatus for a four-wheel-drive vehicle is configured to determine whether or not a degree of a yaw movement for deflecting the vehicle to a left or right side is larger than a predetermined first degree. When the degree of the yaw movement is larger than the first degree, the control apparatus increases a coupling torque of a coupling device corresponding to a rear wheel at the same side as a direction of the yaw movement to a predetermined first torque value, and maintains at zero a coupling torque of a coupling device corresponding to a rear wheel at an opposite side to the direction of the yaw movement.
