Problems solved by technology

[0005] However, in the above-mentioned Patent Document 1, if the oil cut control is released after the slip control is completed, that is, after the lock-up clutch is disengaged, and the fuel supply is resumed, the engine may have a problem from the start of the fuel supply restoration to the actual complete explosion. It takes time, and during this period, the engine speed drops sharply as the lock-up clutch is disengaged, so the control to increase the engine air volume is activated, and the engine speed rises, and a shock may occur
In addition, the engine speed drops sharply, which may produce stalling of the engine
In addition, as described in Patent Document 2, contrary to the above, if the slip control is ended after the oil supply is restored, the engine will explode completely before the lock-up clutch is disengaged. Fuel recovery shock, which deteriorates ride performance

Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0036] figure 1 It is a schematic diagram of a vehicle transmission 10 to which the lockup clutch control device of the present invention is applied. The vehicle transmission 10 is a transverse automatic transmission, which is most suitable for an FF (front-engine, front-wheel drive) type vehicle, and has an engine 12 as a driving force source for traveling. The output of the engine 12 consisting of an internal combustion engine is transmitted from the crankshaft 13 of the engine 12, the torque converter 14 as a fluid transmission device, through the forward and reverse switching device 16, the input shaft 36, the belt type continuously variable transmission (CVT) 18, and the reduction gear device. 20 is transmitted to the differential gear unit 22 to be distributed to the left and right drive wheels 24L, 24R. The transmission mechanism is composed of the ab...

Abstract

A controller of vehicle features that when clutch is just changed from connection state to separation one, it outputs an instruction F to restore the fuel oil supply for making the engine to explode fast and fully and suppressing the fuel oil restoring impaction, so improving the running performance.

Description

technical field [0001] The present invention relates to a vehicle control device for stopping oil supply to the engine when the clutch is engaged during vehicle deceleration in a vehicle that transmits engine power through a transmission clutch, and particularly relates to a vehicle control device that stops oil supply to the engine when the vehicle is decelerated. It is a technology to control the working state of the clutch and the recovery of oil supply to the engine. Background technique [0002] A vehicle having a fluid transmission for a vehicle having a lock-up clutch directly connecting an engine and an automatic transmission is known. For example, such a vehicle is disclosed in Patent Document 1, which discloses a technology that, during deceleration running of such a vehicle, for example, coasting with the accelerator or throttle fully closed, that is, so-called coasting, by executing the lock The slip control in which the clutch is in the engaged state (hereinaft...
