The main motor and the auxiliary motor are respectively connected to input ends of the primary reducer and the secondary reducer. Output ends of the primary reducer and the secondary reducer are respectively connected to a differential housing and an input end of the planetary gear set. Two output ends of the planetary gear set are respectively connected to the three-phase actuator and the dual-gear mechanism. An output end of the dual-gear mechanism is connected to the differential housing. The three-phase actuator is a synchronous shifting mechanism for enabling locking, decoupling of the planetary gear set, and connection to the first half shaft.

A driving force control system for a vehicle is provided to control a torque vectoring device is provided. A controller is configured to bring the torque vectoring device into a preparatory state in which the differential torque and the differential limit torque are equalized to each other when shifting the operating mode between the differential mode and the differential limit mode, and to shift the operating mode of the torque vectoring device by gradually reducing a difference between the differential torque and the differential limit torque.

A vehicle includes a trailer hitch, an axle having an electronic limited slip differential, and a controller. The electronic limited slip differential includes a variable torque capacity lockup clutch. The controller is programmed to, in response to detecting the presence of a trailer connected to the trailer hitch and an increase in vehicle speed, increase the lockup clutch torque by a first torque adjustment.

A drive unit a drive unit which can prevent an occurrence of an unintentional relative rotation between the right and the left wheels is provided. The drive unit comprises: a first motor connected to the first driveshaft and a second motor connected to the second drive shaft; a first torque transmitting route between the first motor and the first drive shaft; a second torque transmitting route between the second motor and the second drive shaft; a first rotary member arranged in the first torque transmitting route; a second rotary member arranged in the second torque transmitting route; and a restriction device that restricts a differential rotation between the first rotary member and the second rotary member.

A hybridized rear axle drive (H-RAD) includes an electrical torque vectoring system (eTV) and a drive train for a motor vehicle, especially a plug-in hybrid vehicle (PHEV), and is configured to perform a method for electric torque distribution (electric torque vectoring).

A method of determining clutch torque for a limited slip differential gear mechanism on a vehicle includes obtaining an estimated driveline torque. A desired bias torque is established. A necessary clutch torque required to achieve the desired bias torque is determined. The necessary clutch torque is commanded based on the estimated driveline torque to achieve the desired bias torque.

The hydraulic system comprises a shifting mechanism (20) and a pump assembly (30) configured to provide pressurized fluid to said shifting mechanism (20), and an electrical motor (40). The movement of the shifting mechanism (20) controls a valve function which serves to open a connection from the pump assembly (30) to the electrical motor (40).

An electrically driven vehicle axle is provided, comprising an electrical machine (6), a left drive shaft (14), a right drive shaft (24), a first clutch (10) connecting the electrical machine to the left drive shaft (14) and a second clutch (20) connecting the electrical machine (6) to the right drive shaft (24). The first and second clutches (10, 20) are arranged concentrically.

A vehicle drive system for an electric vehicle having in-hub motors configured to be independently controlled from the main traction motors. The configuration allows for robust control of the vehicle dynamics and behavior by allowing an improved powertrain control. The system also allows the vehicle to achieve better efficiencies.

Provided is a vehicle that can improve vehicle posture control or operation performance during accelerating turn. A vehicle is provided with: a left drive wheel and a right drive wheel connected to a motor; a required drive power amount input device for inputting a required drive power amount; and a required turn amount input device for inputting a required turn amount.
