Definitions
- the present invention relates to a control device for a vehicle engine provided with a variable valve timing mechanism having an intermediate lock function.
- the intermediate lock is performed in the stop process, and the cam phase is mechanically locked at the lock position before the most retarded angle position.
- the cam phase is fixed before the position.
- the engine at normal temperature starts the engine in a decompressed state in which the cam is retarded to the most retarded position in order to reduce engine start shock. There is a need to do it.
- the intermediate locking mechanism wants to mechanically lock the cam at the lock position before the most retarded position.
- the present invention has been made against the background of the above circumstances, and its object is to limit the output of an electric motor that starts the engine in a vehicle engine having a variable valve timing mechanism having an intermediate lock function.
- An object of the present invention is to provide a vehicular engine control device that can obtain startability of the engine even if there is.
- the gist of the present invention is as follows: (a) an electric motor that rotationally drives an engine to start the engine; a valve timing mechanism that varies a valve timing of an intake valve of the engine; A vehicle engine control device comprising: an intermediate lock mechanism that mechanically locks the valve timing at an intermediate position between the most retarded angle position and the most advanced angle position of the valve timing, (b) When the output limit of the electric motor is predicted when the engine is restarted, the valve timing when the engine is stopped is locked to the intermediate lock position by the intermediate lock mechanism.
- the valve timing when the engine is stopped is set to the intermediate lock.
- the valve timing of the intake valve is fixed at an intermediate position within the retardation range, so that the explosive force at the time of restarting the engine and the restartability thereby are improved.
- the valve timing when the engine is stopped is not locked to the intermediate lock position by the intermediate lock mechanism. And In this way, since there is no output limit of the electric motor when the engine is restarted, the engine can be started from the re-retarded state, and vibration at the time of restart can be reduced.
- the valve timing when the engine is stopped is set to the intermediate lock.
- the mechanism is not locked at the intermediate lock position.
- the valve timing is not locked to the intermediate lock position by the intermediate lock mechanism when the engine is stopped.
- the temperature of the motor Preferably, the temperature of the motor, the temperature of the inverter that controls the drive current of the motor, the temperature rise of the battery that supplies the drive current to the motor, the temperature drop of the battery, and the remaining charge of the battery
- a motor output limit is predicted when the engine is restarted. In this way, the output limit of the electric motor corresponding to the vehicle state is reliably predicted.
