This driving assist apparatus for a vehicle sets target wheel speed of an inside rear wheel in turning to substantially zero when a state of a center differential apparatus is a locked state in a case where the vehicle is turned in an extremely low speed traveling control. Further, the apparatus sets target wheel speed of each of wheels other than the inside rear wheel in turning such that a mean value of target wheel speeds of front wheels is equal to a mean value of target wheel speeds of rear wheels and the mean value of target wheel speeds of front wheels is equal to target vehicle body speed. Furthermore, the apparatus adjusts driving force and braking force such that wheel speed of each of the wheels becomes equal to the target wheel speed set for each of the wheels.

Methods and systems are provided for providing off-road capabilities in electric vehicles with a single gear reduction. In one example, when a 44 mode is selected in an electric vehicle, a relationship between motor torque and accelerator pedal position is changed so as to increase the vehicle creep wheel torque. A degree of increase of the creep wheel torque is adjusted as a function of the terrain on which the vehicle is off-roading.

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.

A vehicle controller may determine a decelerator input associated with controlling an engine speed of an engine of the vehicle. The vehicle controller may determine, while the vehicle is moving and based on the decelerator input satisfying a braking threshold, that an engine decelerator, associated with the decelerator input, is to be enabled for use in stopping the vehicle. The vehicle controller may determine, based on determining that the engine decelerator is to be used to cause the vehicle to be stopped, an amount of braking to be applied by a braking device of the vehicle to stop the vehicle. The vehicle controller may automatically cause the braking device to apply the amount of braking to stop the vehicle.

An exemplary system for controlling creep running of a vehicle equipped with an engine and a transmission includes, a driving information detection unit detecting driving information of the vehicle, an engine controller for controlling an output torque of the engine, and a vehicle control unit controlling the engine controller to output a basic creep driving torque, and when the vehicle is on a sloped road of more than a predetermined inclination, to further output a first additional driving torque corresponding to an inclination of the sloped road.

A control method and a control device are provided for autonomously controlling a host vehicle when turning across an oncoming lane at an intersection with a signal light being green. A determination is made as to whether or not the host vehicle can make a right or left turn while a signal light is still green at a time of the right or left turn, either while the host vehicle in the left lane is waiting in a row of vehicles to make the right turn or while the host vehicle traveling in the right lane is waiting in a row of vehicles to make the left turn at an intersection during travel under autonomous driving. The host vehicle then creeps forward to a start position for starting at a next time the signal light is green upon determining the right or left turn cannot be made.

A vehicle control method is provide for automatically controlling an acceleration-deceleration rate control of a vehicle including starting and stopping. The vehicle control method performs the starting of the vehicle at a starting time with a first drive force which exceeds a starting friction force, which is a friction force acting on the vehicle at the starting time. Then, the vehicle control method switches to a second drive force after performing the starting. The second drive force is greater than the first drive force. The second drive force is a drive force that is necessary to make a headway distance to a preceding vehicle equal to a pre-set headway distance when there is a preceding vehicle. The second drive force is a drive force that is necessary to accelerate to a pre-set vehicle speed when there is no the preceding vehicle.

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.

Certain driver-assist features of a vehicle require incredibly precise longitudinal control of the vehicle. Achieving the precise control requires up-to-date knowledge of performance parameters of a brake system of the vehicle, which may vary extensively based on a wide set of influences outside the control of the brake system. The present disclosure proposes techniques to determine these parameters, for example, by stopping the vehicle early in maneuvering in order to study the brake performance, so that precise longitudinal control of the vehicle may be realized.

The present disclosure relates to an apparatus and method for controlling a creep torque in an environmentally-friendly vehicle. The apparatus includes detectors that detect driving-related information of the vehicle and a controller that calculates rolling resistance based on the driving-related information and variably controls the creep torque in consideration of the calculated rolling resistance depending on whether the vehicle satisfies a creep cruise control operating condition.
