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 system and a method for preventing instability of a vehicle due to regenerative braking of a rear, may include a first controller configured of distributing braking torque of front and rear wheels for a deceleration level according to a basic regenerative braking distribution ratio on a regenerative brake map on the basis of a driver demand braking amount, and configured of previously reducing a rear-wheel regenerative braking torque of the rear wheel to a first reference value or less than the first reference value in an adjustment section between first and second deceleration; and a second controller connected to the first controller and configured of further reducing the rear-wheel regenerative braking torque to transmit it to the first controller, if a wheel slip value is greater than a reference slip value according to vehicle driving information during braking of the vehicle.

A traction control system for a vehicle having a first wheel driven by a first electric motor including a first set of coil windings, the system comprising a first controller arranged to control current in the coil windings for generating a drive torque for driving the first wheel, and a second controller arranged to determine a maximum wheel velocity based on a first slip ratio value for the first wheel and the vehicle velocity and a minimum wheel velocity based on a second slip ratio value for the first wheel and the vehicle velocity. The second controller communicates to the first controller the maximum and minimum values and a torque demand value corresponding to a drive torque for driving the first wheel. The first controller controls current in the coil windings to generate a drive torque based on the maximum and minimum wheel velocity and torque demand values from the second controller.

Methods and systems are provided for propelling a hybrid electric vehicle under circumstances where a torque degradation event associated with an electric machine that is used for propulsive effort is indicated. In one example, a method may include propelling the vehicle at least in part via a first electric machine that provides torque to front wheels and/or via a second electric machine that provides torque to rear wheels of the vehicle, and continuing to propel the vehicle via adjusting operation of both the first and the second electric machine in response to an indication of a torque degradation event associated with one of the electric machines. In this way, a vehicle shutdown event may be avoided.

According to an embodiment of the present disclosure, a driving force control apparatus for a vehicle includes: a front-wheel driver; a rear-wheel driver; a wheel speed detector; a wheel vibration calculator; an estimated speed calculator that calculates an estimated vehicle speed of the vehicle; a slip-rate calculator that calculates a slip rate of each wheel; and a driving controller that reduces a driving force of the front wheel driver or the rear wheel driver when a slip rate of each wheel is greater than a preset slip rate value. The estimated speed calculator determines that the estimated vehicle speed is greater than an actual speed of the vehicle when the vibration value calculated by the wheel vibration calculator is greater than a preset vibration value.

The controller of the electric vehicle is configured to control the torque of the electric motor using the MT vehicle model based on the operation amount of the accelerator pedal, the operation amount of the pseudo-clutch pedal, and the shift position of the pseudo-shifter. Further, the controller is configured to execute the stall production process for changing the engine output torque used for calculation of the driving wheel torque to zero when the calculated virtual engine speed using the MT vehicle model becomes lower than the prescribed stall engine speed.

The controller of the electric vehicle is configured to control the torque of the electric motor using the MT vehicle model based on the operation amount of the accelerator pedal, the operation amount of the pseudo-clutch pedal, and the shift position of the pseudo-shifter. The electric vehicle also includes a pedal reaction force generator that generates a pedal reaction force in response to the operation of the pseudo-clutch pedal using by the operating of the reaction force actuator. The controller is configured to store the pedal reaction force characteristic simulating the characteristic of the pedal reaction force according to the operation of the clutch pedal. Then, the controller is configured to control the pedal reaction force output by the pedal reaction force generator in response to the operation of the pseudo-clutch pedal using the stored pedal reaction force characteristic.

A method for operating a motor vehicle having multiple drive wheels and multiple drive machines, each drive machines being an electric machine and being allocated to a drive wheel. The method includes: acquiring a total setpoint drive torque; acquiring a current vehicle driving speed, a current steering angle, and optionally, the wheel loads of all drive wheels; determining wheel-individual movement speeds of the drive wheels over the roadway based on the current vehicle driving speed, the current steering angle, a known chassis geometry of the motor vehicle, and optionally, the wheel loads; determining a setpoint wheel speed for each drive wheel based on the determined movement speeds, and distributing the total setpoint drive torque to all drive wheels such that an actual curve path deviates from a setpoint curve path specified by the steering angle; actuating each drive machine to adjust the setpoint wheel speed at the respective drive wheel.

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.
