Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023150345
Kind Code:
A
Abstract:
To provide a vehicle control device which can suppress an erroneous monitoring result of a transmission state of a drive force to drive wheels.SOLUTION: A vehicle control device has: a drive force source; a first computer for outputting a current corresponding to a target value of hydraulic pressure to a solenoid valve for supplying the hydraulic pressure to a clutch provided on a power transmission route between the drive force source and an automatic transmission for transmitting a drive force of the drive force source to drive wheels by gear-changing it; and a second computer for determining a transmission state of the drive force of the drive force source. The first computer acquires at least either of a current detection value of a current output to a solenoid valve detected by current detection means, and a first hydraulic pressure detection value of hydraulic pressure supplied to the clutch detected by hydraulic pressure detection means, and the second computer acquires a second hydraulic pressure detection value detected by the hydraulic pressure detection means, and when at least either of the current detection value and the first hydraulic pressure detection value, and the second hydraulic pressure detection value satisfy release conditions of the clutch, respectively, the control device determines that the transmission of the drive force of the drive force source is blocked.SELECTED DRAWING: Figure 2
