A controller for a motor vehicle powertrain, the controller being configured to control the amount of torque generated by each of a plurality of drive torque sources, each drive torque source being coupled via a respective torque transfer arrangement to a respective group of one or more wheels, the controller being configured to cause a first of the drive torque sources, during acceleration, deceleration and substantially constant speed operation, substantially continually to apply a drive torque to a first group of one or more wheels to which the first drive torque source is coupled acting in a first direction relative to a longitudinal axis of the vehicle and causes a second of the drive torque sources, during acceleration, deceleration and substantially constant speed operation, substantially continually to apply a drive torque to a second group of one or more wheels to which the second drive torque source is coupled, the direction of drive torque applied to the second group being in a second direction opposite the first such that a net drive torque applied to the first and second group in combination corresponds substantially to a predetermined drive torque demand value, the predetermined torque demand value being determined at least in part by reference to a torque demand signal received by the controller.

A system and a method for controlling a torque of an electric vehicle are provided. The system includes a driving information detecting unit that detects a speed of the electric vehicle and a position of an accelerator pedal and a controller that applies an offset torque input from a driver to a basic creep torque line set for creep driving of the electric vehicle to set an offset torque line varied from the basic creep torque line in a negative (−) torque direction. Additionally, the controller calculates a basic creep torque depending on the speed of the electric vehicle based on the basic creep torque line when the offset torque is not input and calculates a driver creep torque depending on the speed of the electric vehicle based on the offset torque line when the offset torque is input.

A method for controlling a creep torque of a motor-driven vehicle includes a gradient calculating step of calculating a gradient of a traveling road, and a time constant calculating step of calculating a time constant of a filter using the gradient, a preset basic creep torque, and a sliding speed limiting value. A variable controlling step substitutes the calculated time constant for the time constant of the filter, inputs the basic creep torque to the filter, and controls the motor using a torque value output from the filter as a demanded torque.

A drive control system for a motor vehicle operated by electric motor has a drive position selector device and an electronic control unit which is connected to the drive position selector. The drive control system is configured in such a way that when a first alternative automatic drive position is selected a comparatively high, not freely selectable recuperation level can be predefined and crawl mode is deactivated, and when a second alternative automatic drive position is selected at least one constant recuperation level or a sailing mode can be predefined and crawl mode is activated.

Systems and methods to control the vehicle speed of a vehicle includes a motor and a controller coupled to the motor. The controller is structured to: determine that a speed of a vehicle is at or above a predetermined speed limit; activate a motor speed governor responsive to an input received by the controller, wherein the motor speed governor is structured to control a vehicle speed; and adjust an output torque based on the vehicle speed being at or above the predetermined speed limit.

A drive for a machine includes a computer configured to control a first electric motor for driving vehicle wheels and a second electric motor for driving a work attachment. The second electric motor is configured to drive at least one hydraulic pump with an adjustable stroke volume. A sensor is configured to detect the stroke volume of the pump. The computer processes the stroke volume to control the second electric motor.

A vehicle, e.g., a two-wheeled electric vehicle, is operable in a low-speed mode, in which the vehicle can be propelled selectively in the forward or reverse direction, at a speed limited to approximately an average person's walking speed, e.g., approximately 3 mph. The amount of torque driving the vehicle is controlled so that higher torque is available to propel the vehicle at lower speeds and lower torque is available to propel the vehicle at higher speeds. The maximum torque of the vehicle's electric motor is available to propel the vehicle at a standstill.

The present disclosure relates to a creep speed control system for a vehicle having at least one electric motor for providing torque to at least one vehicle wheel. The system comprises an input configured to receive a current speed signal indicative of a current speed of the vehicle; a creep speed control module that is configured to activate when the current speed of the vehicle crosses a predetermined threshold above a creep speed target value; and, an output configured to, upon activation of the creep speed control module, send a creep speed control torque signal to the at least one electric motor to control the vehicle speed in dependence on the creep speed target value, wherein the creep speed control torque signal is limited to a creep speed control filtered torque value less than a creep speed control maximum torque value.

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.

An electric vehicle (EV) battery unit and installation method is provided herein. The EV battery unit includes a modular housing with a central section with batteries positioned therein and a first lateral section with a battery cooler that is designed to reduce a temperature of the batteries and an inverter that is positioned therein and electrically coupled to the batteries. The modular housing further includes a first frame attachment interface profiled to attach to a first longitudinal frame rail in an EV and a second frame attachment interface profiled to attach to a second longitudinal frame rail in the EV, where the batteries are positioned laterally between the first and second frame attachment interfaces.
