摘要： A control system for and a method of controlling a wheel hub clutch for a wheel hub. The control system includes: a stator; a translator having a permanent magnet; and wiring electrically connecting the stator to an electric power source. The stator is selectively powered through controlled electric power carried by the wiring so as to control translation of the translator through interaction between the stator and the permanent magnet of the translator, and the translation of the translator is controlled between an engaged state and a disengaged state. In the engaged state, a plurality of locking members are engaged with a plurality of notches of a selectively rotatable notch plate whereby the plurality of locking members are in a plurality of pockets of a rotatable pocket plate corresponding to the plurality of notches.

摘要： A vehicle control apparatus for a vehicle including at least two wheel-pairs of right and left wheels includes one or more processors, and one or more memories communicably coupled to the one or more processors. Upon straight traveling of the vehicle, the one or more processors predicts time of generation of a difference in a suspension stroke amount between the right and left wheels in any one wheel-pair out of the at least two wheel-pairs, and reduces driving torque adapted to drive the right and left wheels in the one wheel-pair of the first vehicle at or before the time of the generation predicted.

摘要： A method of controlling torque of a drive system of an electric vehicle is to provide a drive system torque command generation and torque control method of an electric vehicle capable of generating torque and improving vehicle responsiveness and behavioral responsiveness. The method of controlling torque of a drive system of an electric vehicle includes performing backlash control for limiting a torque slope of a front wheel torque command while the front wheel torque command passes through a backlash band, which is a torque region where there is possibility that backlash occurs in a front wheel-side drive system, and generating a braking torque command for generating a friction braking torque while the backlash control is performed.

摘要： Various disclosed embodiments include illustrative controller units, vehicles, and methods. In an illustrative embodiment, a controller unit includes a processor and a memory. The memory is configured to store computer-executable instructions configured to cause the processor to receive a request to perform a mechanical load transition between a motor and a mechanical load, send a torque request to the motor responsive to the received request, receive a motor speed value, determine status of the mechanical load transition responsive to the received request and the motor speed value, and output the determined status.

摘要： A computer system comprising processing circuitry configured to handle wheel slip a vehicle is provided. The vehicle comprises a first axle. The first axle comprises at least two wheels. Each of the at least two wheels of the first axle is drivable by at least two hydraulic motors. The processing circuitry is configured to obtain a slip condition of the vehicle. The processing circuitry is configured to, based on the obtained slip condition, trigger an adjustment of pressure and/or flow to be supplied to at least one of the at least two hydraulic motors in the vehicle. Triggering the adjustment comprises triggering an adjustment of pressure and/or flow between at least two hydraulic motors, and/or triggering adjustment of pressure and/or flow supplied by a source.
