A vehicle control system for controlling an output of a drive source in a vehicle includes: a drive operation member configured to receive an input regarding a driving force for the vehicle from a driver of the vehicle; and a control device configured to cause the drive source to output a driving force corresponding to the input to the drive operation member. When the control device determines that a predetermined enabling condition is satisfied, the control device enables drive restriction for limiting the output of the drive source. The enabling condition includes an input condition which is based on the input to the drive operation member acquired during a predetermined period before start of the drive source.

The invention provides to a method for controlling a vehicle (1) with an internal combustion engine (2) and a transmission (3), the transmission being arranged to automatically provide shifts between a plurality of gear ratios between the engine and at least one driven wheel (5) of the vehicle, characterized by the steps of: registering (S1, S108) a decrease of a demanded torque from an engine control input device (8) of the vehicle, controlling (S2, S109) in response to the demanded torque decrease the rotational speed of the engine so as to not be below a rotational speed threshold value which is above an idle speed of the engine, and where said rotational speed threshold value is determined so as for a transmission gear down shift to be avoided.

Disclosed is a gear shift control method of a Dual Clutch Transmission (DCT) vehicle. The gear shift control method includes a gear shift start determination step of determining whether a kick down shift, a biaxial shift determination step of determining, when the kick down shift is started, whether the gear shift is a biaxial shift; a clutch torque control step of uniformly decreasing torque of a release-side clutch and uniformly increasing torque of a connection-side clutch to synchronize revolutions per minute of a target gear input shaft with increasing revolutions per minute of an engine, a clutch synchronization determination step of determining whether the revolutions per minute of the target gear input shaft is synchronized with the revolutions per minute of the engine by the clutch torque control, and a gear shift performing step of performing gear shift control for engaging the target gear.

An electronic control unit controls a motor so that a torque applied to an input shaft does not exceed an upper limit torque. The electronic control unit sets so as to restrict the upper limit torque from a first torque to a second torque smaller than the first torque, and then return the upper limit torque to the first torque more gradually when a first condition that a driver is assumed to have felt a decrease in driving force output to driving wheels is met before the upper limit torque is returned than when the first condition is not met.

A vehicle control apparatus executes an acceleration suppression control to suppress an acceleration of an own vehicle when an operating condition including a condition that an accelerator pedal operation amount is equal to or greater than a predetermined threshold value is satisfied. The vehicle control apparatus sets the predetermined threshold value to a smaller value when an object entry condition that an object has a possibility to enter an area in front of the own vehicle, is satisfied than when the object entry condition is not satisfied.

A driving assistance control section of a vehicle control apparatus has an operation state of a driver's vehicle transition from a stop state to a start-stand-by state keeping a second assistance state, if an accelerating operation larger than a predetermined first threshold acceleration is performed and there is an ahead-located vehicle, and has the driving assistance state transition from the second assistance state to a first assistance state and has the operation state transition from the stop state to the start-stand-by state if an accelerating operation larger than a predetermined second threshold acceleration is performed over a longer time than a predetermined threshold duration and there is an ahead-located vehicle, if follow-up running control is being performed in the second assistance state in which it is not necessary for a driver to hold a steering wheel to continue to have a driving assistance function performed.

Introduction of a low fuel consumption technique such as downsizing turbos and idling stop decreases an intake pipe negative pressure (pump loss) of an internal combustion engine, and results in difficulty in emitting (evaporative fuel purge) a volatile fuel (volatile fuel) in a fuel tank by the negative pressure of the intake pipe of the internal combustion engine. A control device includes: a purge control unit which controls a purge valve which emits a volatile fuel of a fuel tank or a canister to an intake pipe of an internal combustion engine; and a power transmission control unit which controls a power transmission mechanism between the internal combustion engine and a drive wheel, and, in a state where the power transmission control unit disconnects a clutch, and the vehicle is coasting, the purge control unit opens the evaporative fuel valve and purges an evaporative fuel to the intake pipe.

A vehicle controller may initiate an auto stop of an engine in response to a value of an auto stop parameter falling within a specified range and alter the specified range based on learned information derived from vehicle data to change a frequency or duration of auto stops of the engine.

Apparatus for a vehicle is provided such that the throttle pedal can act as a virtual footrest. The apparatus comprises a pedal adapted to be depressed by a driver and a restriction mechanism adapted to restrict the displacement of the pedal. The apparatus also comprises a visual sign which enters a first illuminated state in response to activation of the footrest mode. The visual sign remains in the first illuminated state whilst the restriction mechanism retains the pedal in the footrest position, and is extinguished when footrest mode or cruise control is cancelled. The visual sign enters a second illuminated state when the pedal is subjected to a force greater than a first threshold value, so as to push the pedal past through the footrest position whilst in the footrest mode.

A vehicle capable of regenerative braking includes a motor that is configured to be driven with electric power. The vehicle selectively sets a drive mode of the vehicle in an accelerator-off state between an ordinary mode and a deceleration enhanced mode that decelerates the vehicle with higher deceleration force than deceleration force in the ordinary mode. The vehicle performs regenerative control of the motor in the ordinary mode or performs deceleration control of generating the deceleration force in the deceleration enhanced mode, in order to decelerate the vehicle in the set drive mode. When an accelerator stroke based on a driver's depression of an accelerator becomes higher than a cancellation threshold in the drive mode set to the deceleration enhanced mode, the cancellation threshold being determined in advance corresponding to the accelerator stroke being greater than zero, the vehicle changes the drive mode from the deceleration enhanced mode to the ordinary mode.
