HYBRID VEHICLE CREEP CONTROL
Aspects of the present invention relate to a method and to a control system for controlling movement of a vehicle to provide vehicle creep, the vehicle comprising an engine and an electric traction motor, the control system comprising one or more controllers, wherein the control system is configured to: while a torque path between the engine and a first set of vehicle wheels is disconnected, control the electric traction motor to provide tractive torque to a second set of vehicle wheels to automatically move the vehicle to provide electric vehicle creep, wherein the electric vehicle creep is controlled by a mathematical model of engine creep torque that would be provided by the engine when the torque path between the engine and the first set of vehicle wheels is connected.
Electrified vehicle one pedal drive transition control
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.
Electric drive vehicle with low speed creep
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.

An embodiment method of controlling traveling of an electrified vehicle equipped with an electric motor as a power source includes determining whether it is possible to enter a variable control function. The variable control function includes a function of variably controlling a coasting torque level using a regenerative braking force. In response to a determination that it is not possible to enter the variable control function, a cause of an inability to enter the variable control function is determined and control is performed in a manner that corresponds to a determination that it is possible to enter the variable control function or the determination of the cause of the inability to enter the variable control function in response to the determination that it is not possible to enter the variable control function.
METHOD AND APPARATUS FOR CONTROLLING NEW ENERGY VEHICLE
The present application relates to the technical field of new energy vehicles- and provides a method and an apparatus for controlling a new energy vehicle. The control method comprises: detecting whether a single pedal control mode is activated; and controlling the new energy vehicle to enter a creep mode according to at least one of a gear position of the new energy vehicle, an action of a brake pedal of the new energy vehicle, and a speed of the new energy vehicle, when it is detected that the single pedal control mode is activated. The present application is able to control the switch of the creep mode according to the driving intention.
System and method for controlling a vehicle
A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.
ELECTRIC VEHICLE PROPULSION SYSTEM AND PROPULSION SYSTEM OPERATING METHOD
Methods and systems for an electric vehicle (EV) propulsion are provided. A method for operating an EV propulsion system is provided, in one example, that includes, while a traction battery assembly generates electric power, initiating start-up of a hydrogen fuel cell assembly based on a first battery state of charge (SOC) threshold and a first hydrogen fuel storage threshold to transition into a hybrid mode of operation. In the propulsion system, the traction battery assembly includes one or more traction batteries that are electrically coupled to one or more hydrogen fuel cells in the hydrogen fuel cell assembly via a distribution assembly, where the distribution assembly is electrically coupled to a traction motor.
HYBRID ELECTRIC VEHICLE CREEP CONTROL
A vehicle includes an engine, and a transmission including a torque converter having an impeller. The vehicle further includes an electric machine configured to provide drive torque to the impeller. The impeller is selectively coupled to the engine via a clutch.
