Problems solved by technology

[0009] However, when the actual pressure is fed back to set the indicated pressure of the clutch, the timing of engaging the clutch will deviate due to the deviation of the actual pressure of the clutch, and the clutch may be engaged incorrectly.
[0010] In this way, when the driving source stop control is released during running and the clutch is engaged, the clutch may be mistakenly engaged.

Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the gear ratio is the value obtained by dividing the rotation speed of the input shaft of the continuously variable transmission by the rotation speed of the output shaft of the continuously variable transmission. The case where the transmission ratio is large is called low gear, and the case of low transmission ratio is called high gear. .

[0019] figure 1 It is a schematic configuration diagram of the vehicle of this embodiment. The vehicle includes an engine 1, a hydraulic torque converter 2, a power transmission mechanism that is a forward / backward switching mechanism 3, a continuously variable transmission (transmission mechanism) 4, a hydraulic control circuit 5, a first oil pump 6m, a second oil pump 6e, and an engine controller 10. , Transmission controller 11. In the vehicle, the rotation generated by the engine 1 is transmitted to w...

Abstract

A vehicle control device for controlling a vehicle having a drive source and an automatic transmission connected to the drive source and having a power transmission mechanism having a forward coupling element, the vehicle control device having : The first control unit executes the driving source stop control during running to stop the driving source and set the automatic transmission in a neutral state when the driving source stop condition is satisfied while the driving source is stopped; the second control unit , after the driving source stop canceling condition is satisfied during running, the forward coupling element is coupled based on the input and output rotational speeds of the power transmission mechanism.

Description

Technical field [0001] The invention relates to a vehicle control device and a vehicle control method. Background technique [0002] Currently, JP2013-213557A discloses a control device for a vehicle that stops the engine, releases the clutch, and executes driving source stop control during traveling without depressing the accelerator pedal. [0003] As the above-mentioned driving source stop control during driving, for example, the following driving stop control is also known, that is, when the gear selector is in the D position, the vehicle speed is medium or high, the accelerator pedal is not depressed, and the brake is not depressed With the pedal, stop the engine and release the clutch. [0004] For example, when the running stop control is released and the clutch is engaged, for example, the clutch is engaged in the following procedure. [0005] (1) After the travel stop cancellation condition is established, the clutch is pre-supplied with hydraulic pressure for the piston str...
