Abstract:
PROBLEM TO BE SOLVED: To provide an on-vehicle control device that can restart a stopped engine when an acceleration request by a driver occurs, and perform smooth acceleration when a clutch between the engine and an automatic transmission is fastened.SOLUTION: When an acceleration request by a driver occurs, a stopped engine is restarted, and a power transmission mechanism between the engine and wheels is fastened to accelerate a vehicle. A target transmission gear ratio of a transmission at least according to an acceleration operation amount is obtained, and a transmission gear ratio after a restart condition is established is controlled based on the target transmission gear ratio. According to this, by appropriately controlling the target transmission gear ratio of the transmission based on the driver's acceleration operation amount, it is possible to acquire smooth acceleration feelings and suppress the deterioration of drivability.SELECTED DRAWING: Figure 3
