The method comprises the steps of determining a specified setpoint drive torque (11) of the motor vehicle (1) for a current driving situation of the motor vehicle (1); sensing a first rotational speed (7a) of the first asynchronous machine (2) and a second rotational speed (7b) of the second asynchronous machine (3); determining a common operating strategy of the first asynchronous machine (2) and of the second asynchronous machine (3) according to the specified setpoint torque (11) while taking into account the sensed rotational speeds (7a; 7b); and controlling the stator voltage (5) and the stator frequency (6) in order to set the drive torques (9a; 9b) of the asynchronous machines (2; 3) according to the operating strategy.

A method to control a road vehicle driven by a driver and provided with at least a first drive wheel and a second driver wheel belonging to a same axle, each drive wheel being independently operated by a respective first and second electric motor; the control method comprises the step of controlling the torque delivered by each respective motor to the first drive wheel or to the second drive wheel as a function of a torque requested by the driver and independently of the difference in angular speed between the first and the second wheel.

A method for controlling driving force of a vehicle includes: determining, by a controller, a basic torque command on the basis of vehicle operation information collected while a vehicle is driven; obtaining, by the controller, tire vertical load information and vehicle pitch motion information in real time during the vehicle is driven on the basis of the information collected from the vehicle; determining, by the controller, a final torque command using the determined basic torque command and the obtained tire vertical load information and vehicle pitch motion information; and controlling, by the controller, a torque output of a driving device configured to drive the vehicle according to the determined final torque command.

A system includes a reference speed module and a motor control module. The reference speed module is configured to determine a reference speed range based on a speed of a left wheel of a pair of front or rear wheels of a vehicle and a speed of a right wheel of the pair of front or rear wheels. The right wheel is disconnected from the left wheel. The motor control module is configured to control at least one of a first electric motor and a second electric motor based on the reference speed range. The first electric motor is connected to the left wheel. The second electric motor is connected to the right wheel.

A vehicle includes an electric machine and a controller. The controller is programmed to responsive to a threshold difference, indicative of wheel slip, between average wheel speed and a vehicle speed that is based on a difference between wheel acceleration and measured vehicle acceleration, command a speed to the electric machine to reduce the wheel slip.

A control apparatus for a vehicle includes an addition portion that outputs a post-compensation driver request torque, which is acquired by adding a driving torque (a loss compensation driving torque) lost due to a braking torque provided to a wheel on a low-μ road surface side according to a BLSD request hydraulic pressure calculated by a BLSD request hydraulic pressure calculation processing portion to a driver request torque calculated by a driver request torque calculation processing portion, to a motor.

A control system for a vehicle includes wheel slip control loop including a wheel slip controller configured to control wheel slip based on wheel speed measured at one or more wheels of the vehicle. A wheel flare control loop includes a wheel flare controller configured to control wheel flare based on transmission output speed at an output of a transmission of the vehicle. A controller is configured to select one of the wheel slip controller to control the wheel slip and the wheel flare controller to control the wheel flare during operation of the vehicle.
