Vehicle drive control systems, such as those, for example, configured to permit a vehicle to direct power to at least one drivable element (such as, for example, via a drive shaft, a supplemental drive, or a battery) to assist the vehicle in making a low-radius turn.

A mechanical energy divider includes an input shaft operably connected to a rotational energy source, an output shaft, and a regulator therebetween. The regulator includes a housing comprising an input gear coupled to the input shaft, an output gear coupled to the output shaft, and a regulator gear rotatably coupled to a first end of an axle that is affixed to the housing. A braking mechanism operably connected to the output shaft for preventing the output shaft from rotating above a set limit. Activation of the braking mechanism causes the regulator shaft to rotate, which causes a mechanical energy storage device comprising a cable and attached weight to raise upward, storing the excess energy as potential energy. The regulator rotates in the opposing direction when the input shaft rotates slower than the set limit, which releases the weight, thereby increasing the speed of the output to the set limit.

A vehicle differential disconnect assembly can include a differential case, a differential gear set, and a torque distribution device. The differential gear set is carried within the differential case. The torque distribution device transfers torque between the differential gear set and side shafts of the accompanying vehicle driveline. The torque distribution device can include a clutch pack and an actuator assembly. The clutch pack is located at a first side of the differential case relative to the differential gear set, and the actuator assembly is located at a second side of the differential case relative to the differential gear set. The actuator assembly has a mover that transmits movement to the clutch pack when the actuator assembly actuates and deactuates the clutch pack.

A vehicle drive system configured to achieve a required driving force of braking force without changing an orientation of a vehicle in the event of slippage of a wheel. The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.

Methods and systems for operating axles of a vehicle are provided. In one example, an apparatus is configured to consume a first amount of electric power to indicate a first axle operating state. The apparatus is also configured to consume a second amount of electric power to indicate a second axle operating state.

An electrical axle drive device includes at least one first electrical machine, which has a stator and a rotor rotatable around a machine axis of rotation relative to the stator. A gear unit is drivable by the first electrical machine having at least one first planetary gear stage drivable by the first electrical machine and at least one first spur gear stage drivable by the first electrical machine. The device also includes at least one drive wheel of the motor vehicle being able to be rotated around a wheel axis of rotation running parallel to the machine axis of rotation and being drivable by the first electrical machine via the gear unit. The first electrical machine is arranged at least partially on a first side of the longitudinal central plane with respect to a longitudinal central plane of the vehicle that is spanned by the vehicle vertical direction and the vehicle longitudinal direction and the first spur gear stage is arranged on a second side of the longitudinal central plane opposite the first side in the vehicle transverse direction.
