A drive control system for a motor vehicle able to be operated by an electric motor and having a drive stage selector, an electronic accelerator pedal, a brake pedal, and an electronic control unit that is configured such that a creep function is deactivated when a first alternative automatic drive stage is selected, and that a creep function is activated when a second alternative automatic drive stage is selected. The control unit furthermore contains an appropriately programmed function module by way of which, when the creep function is activated and based on creep pilot control, the creep moment predefined thereby, in the form of a drive moment, is reduced based on a braking request from the driver, wherein a frictional braking moment is activated by the conventional wheel brake system only when the minimum possible creep moment is reached.

A system and method of controlling a vehicle that has an axle assembly and a wheel. Propulsion torque and friction brake torque are simultaneously provided to the wheel with an electric motor and a friction brake, respectively, when braking and acceleration of the vehicle are both requested for a predetermined period of time.

System and method configured to determine a direction of movement of a vehicle in response to a brake being released or in response to initiating movement of the vehicle from a stopped position along a route. The direction of movement is determined based on a selected travel direction of the vehicle, a grade of the route, and at least one of applied tractive efforts or applied braking efforts.

A hybrid vehicle may include an engine, a first rotating electric machine, an output shaft, a planetary gear mechanism, a second rotating electric machine, a battery, an inverter and an electronic control unit. The electronic control unit may be programmed to perform inverterless traveling control. The inverterless traveling control may be control for causing the hybrid vehicle to travel by placing the inverter in a gate cut-off state, and driving the engine. The electronic control unit also may be programmed to interrupt current flowing between the first rotating electric machine and the battery when a shift range other than a forward range is selected, during the inverterless traveling control.

At a time that a parking operation is performed, a vehicle parking control device detects that a power receiving pad of an electric vehicle lies within a characteristics modifying range. Furthermore, the vehicle parking control device detects that other predetermined conditions are satisfied. In the case that the power receiving pad is positioned inside of the characteristics modifying range, and if all of the predetermined conditions have been satisfied, an acceleration-OFF-state movement characteristic of the vehicle, for example, a creep torque characteristic or a brake hydraulic pressure characteristic, is switched to an appropriate characteristic from a characteristic thereof at normal times.

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 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. At least one vehicle controller is configured to, in response to the engine being OFF, the transmission being in DRIVE, a vehicle speed being zero and a brake pedal being released beyond a threshold position, command the electric machine to provide a torque to the impeller. The torque is a predetermined feedforward torque adjusted by a feedback torque that is based on a difference between measured and calculated speeds. The speeds may be the speeds of the electric machine.

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.

A method for operating a motor vehicle including a traction electric motor, wherein the traction electric motor can be actuated for producing a creep torque that brings about a slow movement of the motor vehicle, wherein a plurality of creep torques of different magnitude can be set by a user of the motor vehicle.

Methods and systems are provided for operating a vehicle in a mode to free the vehicle from being stuck in sand are presented. In one example, a speed of an electric machine is adjusted to determine when wheel jitter occurs. The electric machine speed may be maintained at a speed where wheel jitter occurs while the vehicle is stuck.
