A vehicle includes a first axle having a first electric machine, a second axle having a second electric machine and a controller. The controller is programmed to, in a user-selected four-wheel drive mode, command a first torque to the first electric machine based on a driver-demanded torque and a speed of the second axle, and command a second torque to the second electric machine based on a comparison of the driver-demanded torque and the first torque and further based on a speed of the first axle.

An apparatus is provided for adjusting an electrical configuration of a plurality of components of an electrical network associated with a vehicle in order to tune electrical characteristics of the electrical network to continuously match a dynamically changing desired mode of operation of the electrical network associated with the vehicle.

A control method controls an electric four-wheel-drive vehicle to switch a drive torque distribution between a first distribution prioritizing energy efficiency and a second distribution prioritizing driving performance. The distribution is set to the second distribution where wheel slip is detected during a trip, and returned to the first distribution once the vehicle has stopped. When wheel slip is detected at least during acceleration, the distribution is switched from the first distribution to the second distribution. When wheel slip is detected during deceleration, a slip experience flag is set. The slip experience flag is maintained at least until starting off in a subsequent trip. Where the slip experience flag has been set, the distribution is maintained as the second distribution when the vehicle has stopped, and where the slip experience flag has not been set, the distribution is returned to the first distribution upon the vehicle being stopped.

An electrified vehicle may include an electric motor coupled to a battery to propel and brake the vehicle, a pedal generating a pedal position signal including a released position signal, friction brakes configured to provide a stopping force to vehicle wheels, and a controller programmed to control the motor and the brakes in response to the pedal being released to decelerate the vehicle to a stop, and to control the motor and an engine (in hybrid vehicles) to inhibit propulsive torque to the wheels after stopping due to the pedal released position until receiving driver input indicative of a request for moving the vehicle, such as depressing the brake or accelerator pedal, or activating an automated vehicle maneuver, such as a parking maneuver, cruise control, or stop-and-go control. Inhibiting torque may include inhibiting creep torque and/or operating the electric machine to charge the battery when the engine is running.

A control apparatus for a vehicle includes an offset torque calculator configured to perform calculation of offset torque to be applied to at least one wheel of the vehicle. The offset torque is required to stop the vehicle on a sloping road having a predetermined gradient. The control apparatus includes a motor controller configured to, for stopping the vehicle on the sloping road having the predetermined gradient, perform control of causing output torque of the motor-generator to asymptotically approach the offset torque.

A method for distributing a braking torque requested by a driver over the axles of a motor vehicle. The wheels of the first axle are associated with a first friction brake device and a first electrical machine having a first efficiency and the wheels of the second axle are associated with a second friction brake device and a second electrical machine having a second efficiency, in which, according to the method, the allocation of the requested braking torque over the first and/or second axle and the determination of the components of the recuperation torques to be provided by the first and/or second electrical machine of the requested braking torque is carried out taking into consideration the current driving stability of the motor vehicle.

A vehicle-mounted power supply system includes a sampling circuit, a voltage comparison control circuit, a power conversion circuit, and a motor. The sampling circuit is configured to obtain an output voltage value of an output terminal of the power conversion circuit. The voltage comparison control circuit is configured to output a first power adjustment signal to the power conversion circuit when the output voltage value is less than a first target voltage value. The power conversion circuit is configured to increase an output voltage to a first target voltage based on the first power adjustment signal, to output the output voltage to the motor and increase an input voltage of the motor. When a voltage of a power supply is low, the input voltage of the motor can be maintained at a required level.

A drive unit includes an electric motor, an MCU to supply a driving current to the electric motor, and a bracket fixing the MCU to the electric motor with a gap between the MCU and the electric motor. The electric motor includes a stator case accommodating a stator, a first housing including a bearing that supports one side of an output shaft of a rotor, and a second housing including a bearing that supports another side of the output shaft of the rotor. The bracket supporting the MCU is attached to the first housing and the second housing and not to the stator case.
