Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018043592
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a response delay of an internal combustion engine when a driver performs acceleration operation of a vehicle during traveling of the vehicle.SOLUTION: A vehicle control device (17) includes acceleration preparation means (172, 173) for controlling an internal combustion engine (18) so as to suppress a response delay of the internal combustion engine at acceleration for a prescribed period from a point of time when an acceleration request is estimated, when the acceleration request by a driver of a vehicle (1) is estimated, when the vehicle travels using driving force from the internal combustion engine. For example, in a case where a deceleration support is executed since there is a possibility of a lane deviation, when it is estimated that the driver of the vehicle requests for acceleration due to unintended deceleration, an air-to-fuel ratio, an EGR, a throttle opening degree, a compression ratio, a supercharging pressure ratio, valve timing and the like are controlled for a prescribed period so that a state of the internal combustion engine becomes a prescribed state in which output responsiveness of the internal combustion engine can be more enhanced than output responsiveness at the start point of time of the deceleration support.SELECTED DRAWING: Figure 1
