A lane departure prevention apparatus (17) has: a departure preventing device (172) for control a braking apparatus (122) to perform a departure prevention operation by applying yaw moment (M.sub.tgt) to a vehicle (1), wherein the yaw moment is generated by a difference of the braking forces between right wheels (121FR, 121RR) and left wheels (121FL, 121RL)1; and a controlling device (173) for controlling the departure prevention device so that the braking force applied to driving wheels (121RL, 121RR) becomes smaller and the braking force applied to non-driving wheels (121FL, 121FR) becomes larger when the departure prevention operation is performed and a differential apparatus (132) limits a differential rotation, compared to a case where the departure prevention operation is performed and the differential apparatus does not limit the differential rotation.

A method for reducing fuel consumption of a work vehicle may include monitoring one or more loads associated with both a drive power requirement and a hydraulic power requirement for the work vehicle. In addition, the method may include actively adjusting one or more operating parameters of the work vehicle based on the monitored loads in a manner that meets the drive power requirement and the hydraulic power requirement for the work vehicle while reducing the fuel consumption of the vehicle's engine.

Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission are described. In one example, regenerative torque and torque of an electronically controlled differential clutch are adjusted to increase utilization of a vehicle's kinetic energy.

A hybrid vehicle includes an electronic control unit configured to, when the drive mode is changed from one of the series-parallel mode and the parallel mode to the other one of the series-parallel mode and the parallel mode and the speed stage is changed from one of the low speed stage and the high speed stage to the other one of the low speed stage and the high speed stage, selectively execute either one of a first control and a second control. The first control is control in which the drive mode and the speed stage are changed by passing through the series mode. The second control is control in which one of the drive mode and the speed stage is changed and then the other one of the drive mode and the speed stage is changed without passing through the series mode.
