The present disclosure provides an electronic stability control method for a vehicle for performing vehicular electronic stability control simply by adjusting driving force and braking power that are generated by a driving device of the vehicle without use of a driving force distributing method between front, rear, left, or right vehicle wheels. To this end, the vehicular electronic stability control method includes determining a vehicular state value indicating a driving state of a vehicle from information collected from the vehicle, comparing the determined vehicle state value with a first reference value, and controlling an operation of a driving device for generating driving force for driving the vehicle by the controller when the vehicle state value is greater than the first reference value to adjust driving force for preventing understeer or oversteer of the vehicle.

Systems, methods, and other embodiments described herein relate to improving propulsion of a vehicle. In one embodiment, a method includes, in response to detecting a vehicle configuration associated with an arrangement of a set of hub motors that are selectively attachable on driven wheels of the vehicle, loading a control setting according to the arrangement to one of a series configuration and a parallel configuration to indicate a power source for the driven wheels as one or more of a motor of the set of hub motors and a central propulsion system. The set of hub motors is structured to be selectively attached to the driven wheels without removing the driven wheels from the vehicle. The method includes managing power delivery to the set of hub motors and the central propulsion system of the vehicle to propel the vehicle according to the control setting.

Systems and methods are provided herein for operating an electric vehicle in a vehicle yaw mode. The electric vehicle includes a normal driving mode where the electric vehicle is steered by turning the steerable wheels (e.g., left or right) and vehicle yaw mode where the vehicle controls the torque applied to each wheel. In response to receiving input to initiate vehicle yaw mode and yaw direction, the system determines the inner wheels and the outer wheels and provides forward torque to the outer wheels of the vehicle and backward torque to the inner wheels of the vehicle to rotate the vehicle.

Methods and systems for a vehicle transmission are provided herein. The vehicle transmission includes an input interface configured to mechanically couple to a motive power source. The vehicle transmission further includes a first disconnect device releasably mechanically coupling a first output to a first drive axle and a second disconnect device releasably mechanically coupling a second output to a second drive axle.

A system includes a clutch state module and a clutch torque module. The clutch state module is configured to determine whether a clutch of an electronic limited slip differential is locked or unlocked. The electronic limited slip differential couples an engine of a vehicle to left and right wheels of the vehicle. The clutch torque module is configured to estimate an actual torque transferred by the clutch using a first clutch torque model when the electronic limited slip differential is unlocked, and estimate the actual clutch torque using a second clutch torque model when the electronic limited slip differential is locked. The second clutch torque model is different than the first clutch torque model.

Systems and methods are provided herein for operating a vehicle in a K-turn mode. The K-turn mode is engaged in response to determining that an amount that at least one of the front wheels of the vehicle is turned exceeds a turn threshold. While operating in the K-turn mode, forward torque is provided to the front wheels of the vehicle. Further, backward torque is provided to the rear wheels of the vehicle. Yet further, the rear wheels of the vehicle remain substantially in static contact with a ground while the front wheels slip in relation to the ground.

Methods and systems for operating a driveline that includes two electric machines are described. In one example, one electric machine is operated in a generator mode and the other electric machine is operated in a motor mode so that electric power that is generated by the electric machine that is operated in the generator mode is consumed by the electric machine that is operated in the motor mode.

A vehicle includes an electric machine and a controller. The controller is programmed to responsive to a threshold difference, indicative of wheel slip, between average wheel speed and a vehicle speed that is based on a difference between wheel acceleration and measured vehicle acceleration, command a speed to the electric machine to reduce the wheel slip.

A drive unit includes: a rotary electric machine; a rotary electric machine case accommodating the rotary electric machine; an electric power conversion device electrically connected to the rotary electric machine and configured to convert electric power supplied to the rotary electric machine and electric power supplied from the rotary electric machine; and an output shaft extending out from the rotary electric machine case and configured to output power of the rotary electric machine. The electric power conversion device is arranged on one side of the rotary electric machine. The output shaft is arranged between the rotary electric machine and the electric power conversion device.
