A brake apparatus for a vehicle may include: a stator unit fixed to an inside of a wheel of the vehicle, a rotor unit disposed to face the stator unit and rotated by electromagnetic interaction with the stator unit, a disc unit connected to the rotor unit and rotated together with the rotor unit, a pair of caliper units disposed on both sides of the disc unit and configured to generate a braking force by contacting with the disc unit as hydraulic pressure is applied, and a transfer unit connected to the pair of caliper units, and configured to transfer hydraulic pressure applied to one of the pair of caliper units to a remaining one of the pair of caliper units.

An electric vehicle controls turning of the electric vehicle in accordance with the orientation of the wheels and skid steering to match the path and turning radius as indicated by the steering wheel. A processing circuit detects the position of the steering wheel and determines the direction of the turn and the resulting path and turning radius of the electric vehicle. The processing circuit either measures the orientation of the wheels or captures data regarding the turning radius of the electric vehicle. The processing circuit controls the traction motors of the electric vehicle so that the actual path and turning radius of the electric vehicle matches the path and turning radius indicated by the steering wheel. Further, the processing circuit may further control controls the traction motors to attempted to maintain the speed of the electric vehicle as indicated by the throttle.

A wheel hub drive system includes a drive motor with a drive shaft, an input planetary gear set (PGS), an output PGS and an intermediate PGS. Each PGS includes a sun gear, a planet carrier and planet gears provided upon the planet carrier. The drive shaft is rotationally fixed with the sun gear of the input PGS. The planet carrier of the input PGS is rotationally fixed with the sun gear of the intermediate PGS, and the planet carrier of the intermediate PGS is rotationally fixed with the sun gear of the output PGS. The planet carrier of the output PGS is adapted to be rotationally fixed with a rim of a wheel. The output PGS is provided axially in-between the input PGS and the intermediate PGS.

A modular electric wheel assembly includes integral/in-built acceleration and braking componentry and/or steering and suspension componentry allowing for the modular application thereof. Each modular wheel assembly may receive drive control data from various sensors (such as accelerator and brake pedal position sensors, steering column rotational offset sensors and the like), vehicle control systems or the like so as to be able to independently drive, brake, steer and/or provide active suspension for the vehicle. The wheel assemblies may communicate with each other across a wheel assembly vehicular network, wherein a master wheel assembly may receive drive control data and control the slave wheel assemblies accordingly. The modular wheel assemblies may further communicate with each other to receive various sensor data, including rotational speed sensor data so as to be able to detect loss of traction events and the like so as to substantially autonomously take remedial traction control action.
