摘要： An exemplary method for controlling torque at one or more wheels of a vehicle, including controlling both positive torque (acceleration) and negative torque (braking) with a single torque command. According to one embodiment, the method interprets the acceleration and braking intent of the driver, takes into consideration certain special conditions (e.g., vehicle dynamic conditions like wheel slip, over- and under-steer, etc.), and generates one or more individual torque commands that are sent to individual wheels or corners of the vehicle. The individual torque commands may address certain chassis and powertrain functions like acceleration and braking, and may provide full-feature torque control (i.e., acceleration, braking, vehicle dynamics, etc.) on an individual wheel basis. It is also possible for the method to be used in a system where a number of the common chassis, powertrain and/or vehicle dynamic modules have been integrated into a single torque control module or the like.

摘要： A torque distribution system for a vehicle permits the transfer of torque between vehicle wheels using a selectively engagable clutch that is hydraulically engaged using hydraulic pressure provided by a hydraulic transmission pump driven by the engine, allowing for enhanced system functionality and reduced part content in comparison with known torque distribution systems. The system may include an “active-on-demand” clutch that is selectively engagable to transfer torque between a front differential and a rear differential (thereby transferring torque from the front wheels to the rear wheels) as well as an electronically-limited slip differential clutch selectively engagable to transfer torque from one front wheel to the other front wheel through the front differential. Utilization of the transmission hydraulic pump allows pressure to be provided to engage the clutch even when the wheels are stationary, i.e., to launch the vehicle.

摘要： Methods and systems for controlling braking in a vehicle are provided, for example in a vehicle in which regenerative braking is provided using a motor capable of providing regenerative braking on one axle or wheel that does not have a friction brake component. If it is determined that the energy storage system of the vehicle cannot accept additional electrical energy created by the regenerative braking, the electrical energy is transferred to another location such as a motor on another axle or wheel, resulting in a propulsion torque on that axle. In order to maintain the total desired braking consistent with the driver command, friction braking is provided on the axle the regenerative braking energy is transferred to using a friction braking component, based in part upon the amount of propulsion torque, when the energy storage system cannot accept additional electrical energy.

摘要： Methods and apparatus are provided for integrating a torque vectoring differential (TVD) and a stability control system in a motor vehicle. The integrated system is utilized for more efficiently correcting understeer and/or oversteer slides in a motor vehicle. In correcting these slides, the integrated system utilizes the TVD to rotate two wheels on opposite sides of the motor vehicle at different rates to create a yaw moment at the vehicle's center of gravity until the TVD reaches a saturation point and the understeer or oversteer slide is not corrected. Once the saturation point is reached without correcting the understeer or oversteer slide, the stability control system is employed to selectively apply one or more of the vehicle's brakes in a further effort to correct the understeer or oversteer slide.
