Definitions
- the present invention relates to a hybrid vehicle, and more particularly, to a technique that can reliably receive a driver's request to not start an engine when the system is started.
- the driver selects this switch for the purpose of reducing noise in densely populated houses late at night and early in the morning, and reducing exhaust gas in indoor parking lots and garages.
- this switch for example, it is called EV drive mode switch or EV switch.
- a control device for an hybrid vehicle disclosed in Japanese Patent Laid-Open No. 2 0 0 0-2 0 4 9 9 6 has an engine and a mode for transmitting power to wheels, and at least one of the engine and the motor It is possible to set a plurality of modes that automatically move the vehicle, and a hybrid vehicle control device in which one of the modes is selected based on a predetermined condition. In an unfavorable state, the engine control unit that selects a mode for prohibiting or restricting engine start regardless of the predetermined condition is specified.
- a mode for prohibiting or restricting engine start is selected regardless of predetermined conditions. In other words, the driver's intention is reflected in the mode selection.
- the ECU Electronic Control Unit
- the ECU recognizes the EV drive request even if the system start switch (called the start (ST) switch or power ⁇ "switch) is pressed and the EV switch is pressed. Too late, the engine is the system It is a case where it is started immediately after startup.
- the present invention has been made to solve the above-described problems, and its purpose is to accept a driver's request without fail when the driver does not request to start the engine at the time of system startup. Furthermore, it is possible to provide a hybrid vehicle control device, a control method, and a recording medium on which a program for realizing the control method is recorded by a computer, which can avoid engine start according to the request. . : ': / '. ;;: ⁇ " ⁇
- the control device controls a vehicle that uses a power source other than the engine engine as a running source of the vehicle.
- This ⁇ hybrid vehicle includes a first switch that is made by the driver to activate the hybrid system and a second switch that is manipulated by the driver to prevent the engine from being activated.
- the control device includes: a first detection unit that detects whether or not the first ⁇ switch is operated; a second detection unit that detects whether or not the second switch is operated; In response to the operation of the switch: When the control unit that executes the startup process of the hybrid system, the first switch, and the second switch are operated substantially simultaneously, and prior to the operation of the first switch And at least one of the cases where the second switch is made, and a detection unit for detecting a driver's request to execute the start-up process without operating the engine.
- the first switch for starting the hybrid system for example, the system start switch
- the second switch for not operating the engine are operated almost simultaneously;
- the control unit detects a driver's request
- the control unit executes the starting process without operating the engine.
- the hybrid vehicle system when a driver's request to execute the start-up process without operating the engine is detected, the hybrid vehicle system is started without operating the engine. For this reason, the engine start avoidance request can be reliably realized in the driver system start-up process.
- the can lj control unit executes the start-up process without operating the engine if the hybrid vehicle state satisfies the requirement for starting the engine.
- the engine when the driver's request to execute the start-up process without operating the engine is detected and a condition that does not require starting the engine is established, the engine is It is possible to activate the system of a hybrid vehicle without operating it. :
- control device further includes a holding unit that holds a state in which the momentary switch that outputs a signal corresponding to the operation only when the second switch is operated.
- the state of the second switch is maintained, that is, the state in which the second switch is operated immediately after the start timing of operation of the control device by the start processing of the hybrid system is maintained.
- the engine start avoidance request by the user's operation of the second switch can be detected steadily.
- the second detection unit detects whether or not the second switch is operated for a predetermined time after the first switch is operated.
- the operation state of the second switch is detected for a predetermined time period X after the first switch is operated and the control device starts to move by the start-up process of the hybrid system. For this reason, even when the first switch and the second switch are operated almost simultaneously, the operation of the second switch can be reliably detected.
- the second switch is an alternate type switch having a mechanical self-holding mechanism.
- the second switch since the second switch has a mechanical self-holding mechanism, the second switch can be operated before the first switch is operated and before the operation of the control device by the start-up process of the hybrid system. The second switch state can be detected. For this reason, even if the first switch and the 24th switch are operated substantially simultaneously, or if the first switch is operated prior to the operation of the first switch, it is ensured. It is possible to detect the operation of the second switch.
