A method for torque control of an electric vehicle on a slippery road surface and a terminal device are provided. The method includes: presetting a torque-lower-limit-value; setting, when an anti-lock braking system of the electric vehicle is activated, the torque-lower-limit-value as a second numerical value to reduce an absolute value of a reverse torque exerted on the vehicle wheel due to the energy recovery, and the vehicle wheel enters an anti-lock state; maintaining the anti-lock state of the vehicle wheel for a preset first time period; comparing the currently requested torque value with a preset third numerical value after the first time period is passed; and resetting the torque-lower-limit-value to the first numerical value to enable the vehicle wheel to exit the anti-lock state, if the currently requested torque value is greater than the third numerical state.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

An eddy current brake for a vehicle, the eddy current brake comprising a rotor, and an electromagnet arranged to receive current from an electromechanical energy generating means during braking of the vehicle and to induce an eddy current within the rotor.

An electric vehicle control method for controlling a motor based on a torque command value in an electric vehicle includes: a disturbance torque estimation process of calculating a disturbance torque estimation value including an influence of a road surface gradient; a speed parameter acquisition process of acquiring a speed parameter relating to a vehicle speed; and a vehicle state control including a stop process of calculating a stopping basis torque target value so as to converge the torque command value to the disturbance torque estimation value in accordance with a decrease in the speed parameter, and a vibration damping process of calculating a stopping correction torque target value by performing filtering on the stopping basis torque target value.

A vehicle includes a regenerative generator on a front wheel. A braking control device includes an actuator that applies a front wheel torque and a rear wheel torque, and a controller that individually adjusts the front wheel torque and the rear wheel torque. The controller is configured to determine the front wheel torque and the rear wheel torque to zero when a regenerative braking force Fg generated by the regenerative generator has not reached a maximum regenerative force Fx which is a generatable maximum value. On the other hand, the controller is configured to increase the rear wheel torque from zero before increasing the front wheel torque from zero when the regenerative braking force Fg reaches the maximum regenerative force Fx.

An apparatus for controlling driving of a transport vehicle in a goods transport system includes a processing unit providing information on a movement path of the transport vehicle, a motion controller generating a drive signal including front- and rear-wheel torque signals for driving front and rear wheels, respectively, of the transport vehicle, a front-wheel torque controller controlling rotation torque of the front wheel on the basis of the front-wheel torque signal, and a rear-wheel torque controller controlling rotation torque of the rear wheel on the basis of the rear-wheel torque signal. The motion controller includes a position controller generating a positional signal determining a position of the transport vehicle, a speed controller generating a speed signal determining a speed of the transport vehicle, and a torque distributor generating the front- and rear-wheel torque signals.

Methods and systems are provided for a drivetrain system comprising: a first prime mover for supplying a torque to a front axle; a second prime mover for supplying a torque to a rear axle; and a controller configured to, in response to a torque reversal, command the front axle and the rear axle to cross lash zones sequentially.
