Control apparatus for vehicle

Abstract

The invention provides a control apparatus for a vehicle, restraining the degradation of a clutch and improving maneuverability. The control apparatus comprising a driving source which outputs driving force for the vehicle, a clutch which is disposed between the driving source and a driving wheel and generates a transmission torque capability based on a command hydraulic pressure, a traveling mode in which a slip control is performed for a clutch and a revolution speed control is performed in a manner that a revolution speed at a driving source side of the clutch is higher than that at a driving wheel side of the clutch by a predetermined revolution speed, a vehicle stopped state determination device which determines the stopped state for the vehicle, a torque detecting device which detects an actual torque of the driving source, a correcting device for transmission torque capacity when the vehicle stops, reducing the command hydraulic pressure from an initial command hydraulic pressure and setting the command hydraulic pressure when a variation in the actual torque of the driving source along with the reduction of the command hydraulic pressure is determined to end, as a post-correction command hydraulic pressure when a vehicle stopped state.

Description

technical field [0001] The present invention relates to a vehicle control device that performs sliding control of a coupling member between a power source and drive wheels. Background technique [0002] The technology described in Patent Document 1 is disclosed as a vehicle control device. This gazette discloses a technique in which the engine uses the slip mode (hereinafter referred to as "WSC running mode") in which the clutch between the motor and the drive wheels is started while slipping the clutch between the motor and the drive wheels using both the driving forces of the engine and the motor. [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2010-77981 [0004] However, in the WSC running mode, when the driver depresses the brake pedal to bring the vehicle to a stop state, the clutch slipping state continues, causing heat generation and deterioration of the clutch. Therefore, it is conceivable to suppress the heat generation of the clutch by r...

AI Technical Summary

Problems solved by technology

However, if the oil pressure supplied to the clutch is too low, there may be a problem that the transmission torque capacity of the clutch changes from a state of substantially zero (corresponding to the generation start point of the transmission torque capacity) to the release side. released state

In this state, if the driver releases the brake pedal and depresses the accelerator pedal to start, the following problems may occur, that is, it takes time until the clutch starts to have a transmission torque capacity, causing a delay or vibration at the time of starting, and the vehicle may be damaged. Reduced operability
