Definitions
- the first clutch that connects and disconnects the power transmission path between the engine and the electric motor
- the second clutch that can mechanically directly connect the power transmission path between the engine, the electric motor, and the drive wheels.
- the present invention relates to a vehicle control device including a clutch.
- a vehicle including an engine, an electric motor, and a clutch (also referred to as a direct coupling clutch) capable of mechanically directly coupling a power transmission path between the engine and the electric motor and driving wheels is well known.
- a clutch also referred to as a direct coupling clutch
- the engine when the engine is started when the motor travels using only the electric motor as a driving force source, if the driving torque is pulled down, the engine is started by pulling up the electric motor. It has been proposed to suppress shock.
- this is the vehicle described in Patent Document 1.
- Patent Document 1 in a vehicle control device including an engine, an electric motor, and a torque converter with a lock-up clutch provided between the engine and a drive wheel, the electric motor is torqued when the engine is started from motor running.
- the lockup clutch When starting up, the lockup clutch is slip-engaged according to the marginal torque, which is the difference between the maximum torque that can be output by the motor and the torque generated by the motor while the motor is running. It is disclosed. Specifically, in Patent Document 1, when the motor is torqued up when the engine is started from the motor running, the slip amount of the lockup clutch is reduced as the margin torque of the motor (that is, the amount that can be increased) is larger. Is disclosed. That is, the technique described in Patent Document 1 reduces the slip amount of the lockup clutch so that the pull-in at the start of the engine can be sufficiently compensated for when the motor has a relatively large margin torque, so that the margin torque can be reduced. When is relatively small, the engine start shock is mitigated by increasing the slip amount of the lockup clutch.
- a vehicle as described above includes a connection / disconnection clutch that disconnects the engine from the power transmission system when the motor is running.
- a connection / disconnection clutch that disconnects the engine from the power transmission system when the motor is running.
- the torque flowing to the engine side via the connection / disconnection clutch (in other words, at the time of engine start) (The torque capacity of the connecting / disconnecting clutch) is expressed as a drop in the driving torque.
- the change mode of the torque of the connecting / disconnecting clutch is determined based on the engine state (for example, engine friction torque) that changes depending on the oil temperature or the like, and the engine start time that varies depending on the factors that require engine start.
- the actual connection / disconnection clutch torque is obtained by slip-engaging a direct coupling clutch (corresponding to the lock-up clutch of Patent Document 1) provided between the engine and the electric motor and the drive wheels. Even if a deviation occurs between the motor compensation torque and the motor compensation torque, it is possible to suppress the engine start shock.
- the slip amount of the direct coupling clutch is uniformly set in consideration of the above-mentioned deviation, the loss due to the slip of the direct coupling clutch is always generated, and the fuel consumption is deteriorated, or the time until the subsequent reengagement of the direct coupling clutch is increased. Therefore, drivability (for example, driving force responsiveness to the required driving amount; power performance) may be reduced.
- the present invention has been made against the background of the above circumstances.
- the purpose of the present invention is to engage the first clutch when the motor is running with the first clutch released and the second clutch engaged.
- An object of the present invention is to provide a vehicle control device that can achieve both suppression of engine start shock and improvement of fuel consumption or drivability when starting an engine by controlling the engine toward the vehicle.
- the gist of the first invention for achieving the object is as follows: (a) a soot engine, an electric motor, a first clutch for connecting / disconnecting a power transmission path between the engine and the electric motor, the engine, and A second clutch capable of mechanically directly connecting a power transmission path between the electric motor and the drive wheel, with the first clutch released and the second clutch engaged.
- a soot engine an electric motor
- a first clutch for connecting / disconnecting a power transmission path between the engine and the electric motor, the engine
- a second clutch capable of mechanically directly connecting a power transmission path between the electric motor and the drive wheel, with the first clutch released and the second clutch engaged.
- the second invention is the vehicle control device according to the first invention, wherein a fluid transmission device is provided in a power transmission path between the engine and the electric motor and the drive wheel.
- the second clutch is a lock-up clutch capable of directly connecting the input side rotating member and the output side rotating member of the fluid transmission device.
- an automatic transmission that constitutes a part of a power transmission path between the electric motor and the drive wheel is provided.
- the second clutch is an engagement device provided in the automatic transmission.
- the vehicle control device further includes a starter motor that cranks the engine, and the engine is started.
- the starter motor When the starter motor is used, the motor increase torque at the time of starting the engine is made smaller than when the starter is not used.
- the generated engine start shock is originally reduced, and the slip amount of the second clutch is relatively reduced, so that fuel consumption or drivability is improved.
- the engine is started by reliably determining whether or not to use the starter motor based on the cooling water temperature, the amount of supplied power, or the number of operations, so that the engine is reduced by reducing the slip amount of the second clutch. Does not exacerbate the starting shock.
- the fuel is injected into the cylinder of the engine that is stopped from rotating and exploded.
- a start control unit for starting the engine and when starting the engine, the engine is started by the start control unit than when the engine is not started by the start control unit.
- the torque of the motor to be increased is reduced.
- the generated engine start shock is originally reduced and the slip amount of the second clutch is relatively reduced. Fuel consumption or drivability is ensured.
- the second clutch is used to start the engine by reliably determining whether the start control unit can start the engine based on the engine rotation stop position (crank angle at the time of engine rotation stop) or the like.
- the engine start shock is not worsened by reducing the slip amount of the engine.
- FIG. 6 is a flowchart for explaining a control operation for achieving both suppression of engine start shock and improvement of fuel consumption or drivability. It is a time chart at the time of performing the control action shown in the flowchart of FIG.
- the automatic transmission is constituted by an automatic transmission having the fluid transmission device, an automatic transmission having a sub-transmission, or the like.
- This automatic transmission is a known planetary gear type automatic transmission in which a plurality of gear stages are selectively achieved by selectively connecting rotating elements of a plurality of sets of planetary gear devices by an engagement device.
- synchronous mesh type parallel two-shaft transmission having a plurality of pairs of meshing gears between two shafts
- synchronous mesh parallel type A so-called DCT (Dual-Clutch-Transmission) type which is a two-shaft automatic transmission but with two input shafts
- the second clutch constitutes a forward / reverse switching device provided together with the engagement device involved in the shift of the automatic transmission, the input clutch of the automatic transmission, and the continuously variable transmission.
