Definitions
- the present invention relates to an engine control device that prevents an engine start failure or an engine start device failure in a vehicle with an idle stop.
- an engine automatic stop / restart device in which the starter pinion gear is pre-engaged with the ring gear of the engine in order to shorten the engine restart time from the idle stop.
- Patent Document 2 discloses an engine starter that gently engages the pinion gear in advance with the ring gear while the engine prior to engine start is stopped as a noise reduction measure during engine start. .
- Patent Document 3 describes a technique for preventing a failure due to the disengagement between the pinion gear and the ring gear.
- Patent Document 3 can be used to switch the pinion drive means when the vehicle is turned off. Even if it is made to act, it has been difficult to reliably release the meshing of these gears by overcoming the frictional force.
- an engine control device includes a ring gear for transmitting rotational force to an engine, a starting device for starting the engine, and an output rotating shaft of a starter motor of the starting device.
- An idle stop function for stopping the engine during idling of the engine, and a pinion gear driving means for sliding the pinion gear on the output rotation shaft.
- the pinion gear driving means is configured to cause the ring to be in contact with the pinion gear. Acts in the direction of disengagement from the gear and rotates the starter motor of the starter. By, and cancels the engagement.
- the pinion gear driving means acts on the pinion gear in a direction away from the ring gear.
- the meshing is released by rotating a starter motor of the starter.
- the engagement of the pinion gear and the ring gear is reliably released at the end of the operation to prevent the pinion gear and the ring gear from engaging for a long period of time.
- the gap between the gear and the ring gear is fixed due to freezing or rust, and the engine may be difficult to start.As a result of the fixing, the pinion gear does not rotate, and the starter motor becomes overloaded and fails. It is possible to prevent a failure such as a poor return of the pinion gear due to accumulation of rust and dust due to long-term exposure of the helical spline portion of the pinion gear.

- the magnet switch 101b is energized.
- the shift lever 101c is operated and the pinion gear 101e is pushed out to the ring gear side.
- the starter motor 101a is energized and rotated, and the pinion gear 101e connected coaxially also rotates.
- the pinion gear 101e meshes with the ring gear 106, so that the crankshaft 108 is rotated and the piston 112 moves up and down via these mechanisms.
- the ECU 103 can control the energization of the pinion relay 105 and the starter motor relay 104 to start the engine in the same manner as when the driver turns on the starter switch 113. It has become a structure.
- FIG. 2 shows a flowchart of the operation of the engine control apparatus according to the first embodiment of the present invention.
- step S201 it is determined whether an idle stop permission condition is satisfied. If it is determined that this is being established, the process proceeds to step S202.
- step S202 it is determined whether or not there is a meshing release request.
- the meshing release request detects the end of driving by a combination of the driver's seat door closing, the driver's load sensor, the ignition switch state, etc., and issues a meshing release request. If there is a mesh release request, the process proceeds to step S203.
- step S203 it is determined whether or not the engine is stopped. When the engine is stopped, the process proceeds to step S204, and when the engine is not stopped (when the engine is rotating), the process proceeds to step S207.
- step S204 it is determined whether or not the pinion relay is ON. Since the pinion relay is ON when the meshing holding control is being performed, the process proceeds to step S205, where the pinion relay is turned OFF by a command from the ECU. When the meshing holding control is not being performed, the pinion relay is OFF, and the process proceeds from step S204 to step S206.
- step S206 the starter motor relay is turned on by a command from the ECU. Thereby, the pinion gear 101e rotates. At this time, since the pinion gear 101e loses the support of the shift lever in step S204, the rotation of the pinion gear 101e reduces the frictional force between the metal of the pinion gear and the ring gear. Is released.
- step S207 the pinion relay 101e is turned OFF by a command from the ECU.
- the pinion relay is turned off, the pinion gear 101e loses its support by the shift lever, is disengaged from the ring gear by the spring force, and the meshing is released.

- step S302 it is determined whether or not there is a meshing release request.
- the meshing release request detects the end of driving by a combination of the driver's seat door closing, the driver's load sensor, the ignition switch state, etc., and issues a meshing release request. If there is a mesh release request, the process proceeds to step S303.
- step S303 it is determined whether or not the engine is stopped. If the engine is stopped, the process proceeds to step S304. If the engine is not stopped (the engine is rotating), the process proceeds to step S308.
- step S304 it is determined whether or not the pinion relay is ON.
- the pinion relay is OFF, and thus the process proceeds to step S306.
- the process proceeds to step S305, where the pinion relay is turned OFF by a command from the ECU.
- the pinion relay OFF the pinion gear 101e loses the support by the shift lever 101c and tries to come off from the ring gear 106 by the spring force.
- the pinion gear 101e becomes a ring gear by the frictional force between the metal of the pinion gear and the ring gear. 106 remains in the state of being bitten.
- step S306 fuel is injected from the fuel injection valve 110 according to a command from the ECU.
- step S307 the cylinder is ignited by the spark ignition device 109 of the cylinder in which the fuel is injected in step S306.
- the spark ignition device 109 of the cylinder By this ignition, the mixture of the fuel and air in the cylinder burns to generate torque, and the ring gear 106 is rotated by this torque.
