Pulsed control of electric motors, and more particularly, to selectively adjusting one or more of a pulsing frequency, an amplitude of the pulses and/or a duty cycle of the pulses for reducing Noise, Vibration and Harshness (NVH) while maintaining high levels of operating efficiency.

A method of controlling driving of a vehicle using an in-wheel system includes: calculating a time to collision (TTC) by dividing a distance between the vehicle and an obstacle located in front of the vehicle by relative velocity; determining whether the vehicle enters a braking avoidance section, based on the calculated TTC; and generating, by a motor mounted in each wheel, braking force of a brake by an amount of shortage of braking force of the brake compared with a demanded braking force if the vehicle enters the braking avoidance section.

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 system for an electrically driven vehicle includes at least one motor controller configured to control at least one electric motor, with which at least one drive wheel of the vehicle can be driven. The system further includes at least one brake controller configured to control friction brakes, with each of which one of multiple drive wheels and/or non-driven wheels can be braked. The brake controller and the electric motor controller each have a data interface that is a bus interface. The brake controller and the electric motor controller are set up to send and/or receive data with a predefined maximum data transmission rate via the first data interface. The brake controller and the electric motor each have a second data interface, each second data interface being designed to send and/or receive data with a higher data transmission rate than the maximum data transmission rate of the first data interface.

A method for controlling heating of a hybrid vehicle is provided. The vehicle includes a duct flowing air into the indoor of the hybrid vehicle from the outside, a heater core for circulating the coolant heated from an engine inside the duct, a PTC heater heated by the power supplied from a high-voltage battery of the hybrid vehicle inside the duct, and a controller. The controller operates the engine and the PTC heater and heats the air flowing into the indoor of the hybrid vehicle through the duct. The voltage supplied to the PTC heater from a low voltage DC-DC converter (LDC) is changed based on the state of the engine and an auxiliary battery for supplying power to an electric component of the vehicle to apply power to the PTC heater.

There is provided an electrically driven vehicle that well balances calculation volumes and communication volumes of two control devices configured to drive and control motors for driving.
