In this drive system, when the power switch is pressed for less than a predetermined time, the accessory on, ignition on, and ignition off states are repeated in order each time the power switch is pressed, and the driver depresses the brake pedal. When the power switch is pushed, when the system main relay is not turned on, the system main relay is turned on and the power system is started.
Japanese Patent Laying-Open No. 2005-261041

  However, in the drive system described in Patent Document 1, even if the operator of the drive device intends to step on the brake and press the start button, the operation may not be sufficient and the system may not be activated. In such a case, the operator may misunderstand that the system is activated and change the shift position to the drive shift position. However, since the system is not activated, the drive device is not driven, and the operator may not know what to do.

  In the drive system of the present invention, the vehicle equipped with the drive system, and the drive system control method, the shift position is changed to the shift position driven by the operator's operation in a state where the system is not activated and cannot be driven. In this case, it is an object to prompt the operator to perform a transition operation to the activated state.

  In order to achieve the above-described object, the drive system of the present invention, the vehicle equipped with the drive system, and the drive system control method employ the following means.

The drive system of the present invention includes:
A driving device having an electric motor that outputs driving power;
Shift position detecting means for detecting the shift position;
An instruction to input an instruction to change at least two states: a starting state in which driving force can be output from the driving device, and a preparation state in which power can be supplied to the power consuming device but incapable of outputting driving force from the driving device Input means;
An informing means for informing the operator of the message;
When the shift position is changed to the drive position when the system is in the preparation state, the notification is made so that a message prompting the operator to operate the instruction input means to bring the system into the startup state is notified. A control device for controlling the means;
Is provided.

  In this drive system, when the shift position is changed to the drive position when the system is in a ready state, a message prompting the operator to operate the instruction input means to bring the system into an activated state is notified. In this way, when the driver cannot drive, for example, when the operator misunderstands that it is in the activated state and changes the shift position to the driving position, the instruction input means is operated to activate the system. A message prompting the operator to be notified is notified to the operator. Therefore, when the shift position is changed to the shift position driven by the operator in a state where the system is not activated and cannot be driven, the operator is prompted to perform the operation for shifting to the activated state. it can.

  In the drive system of the present invention, the instruction input means includes a power switch that allows an operator to instruct a change in a plurality of states including at least the preparation state and a stop state in which the system is stopped, and a brake operation by the operator. A brake operation detecting means for detecting, the control device detecting that the shift position is a parking position by the shift position detecting means, and detecting the brake operation of the operator by the brake operation detecting means. When the power switch is pressed, the notification to input an instruction to change the system to the activated state and operate the instruction input unit to prompt the system to enter the activated state is notified. When controlling the means, the shift position is Be made a message indicating that pressing the power switch performs the brake operation by the state is a device for controlling the informing means so as to be notified to the operator may be. When multiple operations must be combined to start the system in this way, there is an increased possibility that the operation will be insufficient and the system cannot be started, and the operator will be misunderstood that it is active. Since there are more cases where the shift position is changed to a drive shift position, it is highly meaningful to apply the present invention.

  In the drive system of the present invention, the instruction input means includes means for detecting a brake operation by an operator, and the control device drives the shift position when the system is in the preparation state. When the system is in the preparation state, the notification means is controlled so that the operator is notified of a message prompting the operator to operate the instruction input means to bring the system into the startup state. When the shift position is changed to the driving position and the brake operation detecting means detects an operator's brake operation, a message prompting the user to operate the instruction input means to bring the system into the activated state. The notification means is controlled so that the operator is notified, and the system is activated. It may be assumed to be a device for controlling the braking system. If the shift position is changed to the drive shift position when the brake operation is performed, the system is in an activated state because the operator is likely to output the driving power to the drive unit. If the operator is informed of a message prompting that the system is activated and the system is activated, the operator can be informed of a message urging the system to be activated, and can be smoothly shifted to the activated state.

  In the drive system of the present invention, the control device may change the instruction input means when the shift position is changed to a drive position when the system is in the accessory-on state or the ignition-on state as the preparation state. It may be a device that controls the notification means so that a message prompting the operator to operate and bring the system into the activated state is notified to the operator.

  In the drive system of the present invention, the notifying means may be a means for notifying the operator of the message by voice. In this way, as long as the voice can be heard, for example, a message prompting the system to be activated can be transmitted wherever the operator is looking.

  In the drive system according to the aspect of the invention, the control device controls the notification unit so that a message prompting the operator to operate the instruction input unit to put the system into the startup state is notified. When the state is reached, the device may be a device that controls the notifying unit so that the operator is notified of a message indicating that the state has been started. In this way, the operator can easily recognize that the system has been activated.

  The automobile of the present invention includes any one of the above-described driving systems of the present invention, that is, basically a driving apparatus having an electric motor that outputs driving power, and shift position detecting means for detecting a shift position. An instruction to change at least two states, that is, an activation state in which driving force can be output from the driving device and a preparation state in which power can be supplied to the power consuming device but cannot output driving force, is input. An instruction input means, an informing means for informing a message to an operator, and when the system is in the preparation state, when the shift position is changed to a driving position, the instruction input means is operated to activate the system in the activated state. A drive system according to the present invention comprising: a control device that controls the notification means so that a message prompting the operator to notify the operator is provided; The device is intended to travel as power source.

  In the automobile of the present invention, since the drive system of the present invention according to any one of the above-described aspects is mounted, the effects of the drive system of the present invention, for example, operation in a state where the system is not activated and cannot be driven are performed. If the shift position is changed to the shift position that is driven by the operator's operation, the operator can be prompted to perform the transition operation to the activated state, or if the voice can be heard, for example, where is the operator Even if the user is watching, it is possible to achieve the same effect as the effect of transmitting a message for prompting the system to be activated.

The drive system control method according to the present invention includes a drive device having an electric motor that outputs drive power, shift position detection means for detecting a shift position, an activation state capable of outputting drive force from the drive device, and power consumption. An instruction input means for inputting an instruction to change at least two states, a preparation state in which power can be supplied to the apparatus but a driving force cannot be output from the drive device; an informing means for informing a message to the operator; A drive system control method comprising:
When the shift position is changed to the drive position when the system is in the preparation state, the notification is made so that a message prompting the operator to operate the instruction input means to bring the system into the startup state is notified. Including the step of controlling the means.

  In this drive system control method, when the system is in the ready state, when the shift position is changed to the drive position, the operator is informed of a message that prompts the user to operate the instruction input means to activate the system. The informing means is controlled to do so. In this way, when the driver cannot drive, for example, when the operator misunderstands that it is in the activated state and changes the shift position to the driving position, the instruction input means is operated to activate the system. A message prompting the operator to be notified is notified to the operator. Therefore, when the shift position is changed to the shift position driven by the operator in a state where the system is not activated and cannot be driven, the operator is prompted to perform the operation for shifting to the activated state. it can. In the drive system control method of the present invention, steps for realizing the functions and functions of various configurations included in the drive system described above may be added.

  Next, the best mode for carrying out the present invention will be described using examples.

  FIG. 1 is a configuration diagram showing an outline of a configuration of a hybrid vehicle 20 that functions as a drive system according to an embodiment of the present invention. The hybrid vehicle 20 according to the embodiment includes a power system 30 that outputs power to a drive shaft 22 connected to drive wheels 26 a and 26 b via a differential gear 24, and a device that controls the start of the vehicle including the power system 30. And a power supply electronic control unit (hereinafter referred to as a power supply ECU) 62.

  The power system 30 includes an engine 32, an engine electronic control unit (hereinafter referred to as an engine ECU) 36 that controls the operation of the engine 32, a carrier connected to the crankshaft 34 of the engine 32, and a ring gear connected to the drive shaft 22. Are connected to each other, a power generating motor 40 connected to the sun gear of the planetary gear mechanism 38, a power generating motor 41 for inputting / outputting power to / from the drive shaft 22, and driving of the motors 40, 41. Inverters 42 and 43 as circuits, a battery 44 as a power source connected to the inverters 42 and 43 and other auxiliary machines 48 included in the power system 30 via a system main relay 46, and the entire power system 30 are controlled. Electronic control unit for hybrid (hereinafter referred to as HVECU) Say.) Equipped with a 50 and.

  The HVECU 50 is configured as a microcomputer centering on a CPU (not shown), and includes a ROM that stores a processing program, a RAM that temporarily stores data, an input / output port, a communication port, and the like in addition to the CPU. The HVECU 50 includes a rotation position from a rotation position detection sensor (not shown) that detects the rotation position of the rotor of the motors 40 and 41, and a current sensor (not shown) attached to the power line from the inverters 42 and 43 to the motors 41 and 42. Phase current, output voltage and output current from a voltage sensor (not shown) installed near the output terminal of the battery 44, battery temperature from a temperature sensor (not shown) attached to the battery 44, and operating position of the shift lever 81 A shift position from the shift position sensor 82 to be detected, an accelerator opening from an accelerator pedal position sensor (not shown) that detects an amount of depression of an accelerator pedal, and a brake pedal from a brake pedal position sensor (not shown) that detects an amount of depression of a brake pedal Jishon are input data from various sensors for detecting the state of the drive system and a vehicle speed from a vehicle speed sensor (not shown) via the input port. The HVECU 50 outputs a switching signal to the inverters 42 and 43, a drive signal to the auxiliary machine 48, and the like. The HVECU 50 is connected to the engine ECU 36 via a communication port, and receives detection signals from various sensors attached to the engine 32 from the engine ECU 36 and calculation results calculated based on the detection signals as necessary. In addition, a control signal is output to the engine ECU 36 as a command for controlling the operation of the engine 32. The HVECU 50 is connected to the power supply ECU 62 via a communication port, and receives an ignition signal (IG signal), a start signal (ST signal), and the like from the power supply ECU 62 and indicates the activation state of the power system 30 to the power supply ECU 62. A ready signal (RDY signal) is output.

  The HVECU 50 calculates a required torque to be output to the drive shaft 22 based on the accelerator opening corresponding to the amount of depression of the accelerator pedal by the operator and the vehicle speed, and the required power corresponding to this required torque is output to the drive shaft 22. In addition, the operating point of the engine 32 and the torque command of the motors 40 and 41 are calculated so that the remaining capacity (SOC) of the battery 44 is within a predetermined range and the engine 32 is operated efficiently. The operation point of the engine 32 is output to the engine ECU 36 to cause the engine ECU 36 to control the operation of the engine 32. With respect to the torque commands of the motors 40 and 41, the torque corresponding to the torque command is output from the motors 40 and 41. A switching signal is output to inverters 42 and 43 to 40 and 41 for controlling driving. Since detailed control of the power system 30 does not form the core of the present invention, further detailed description is omitted.

  The power supply ECU 62 is configured as a microcomputer centering on a CPU (not shown), and includes a ROM that stores a processing program, a RAM that temporarily stores data, an input / output port, a communication port, and the like in addition to the CPU. In the power supply ECU 62, a push signal from a power switch 72 attached to a front panel of the driver's seat, a brake switch signal from a brake switch 74 that detects depression of a brake pedal (not shown), and a shift that detects an operation position of the shift lever 81 are detected. A shift position or the like from the position sensor 82 is input via the input port. Further, from the power supply ECU 62, a drive signal to the system main relay 46, a lighting signal to the indicator 73 built in the power switch 72, a control signal to the amplifier 89 driving the speaker 89a installed in the passenger compartment 90, A control signal or the like to the display panel 90a installed in the passenger compartment 90 is output via the output port. As described above, the power supply ECU 62 is connected to the HVECU 50 of the power system 30 via the communication port, and based on a push signal from the power switch 72, a brake switch signal from the brake switch 74, etc. Control of turning on and off the power to the power consuming device 92 such as a fan of an air conditioner, turning on and off the power to the power system 30 which is a high power consuming device (ON / OFF of the system main relay 46) and Controls startup.

  Whenever the power switch 72 inputs a short push signal for which the power switch 72 is pressed for less than a predetermined time (for example, less than 3 seconds), the accessory ON ( ACCON), ignition on (IGON) for connecting the battery 44 as a power source of the power system 30 (high power consumption device) by the system main relay 46, the power source of the power consumption device 92 and the power system 30 (high power consumption device) Control is performed so that each of the ignition-off (IGOFF) states in which the connection of the battery 44 as the power source is released and the system is stopped is repeated in this order. Among these, the ignition on and the ignition off are output as an ignition signal (IG signal) to the HVECU 50 of the power system 30 and a drive signal as an on / off signal is output to the system main relay 46. That is, when the power switch 72 is pressed while the accessory is on, the power supply ECU 62 outputs an ON signal as an IG signal to the HVECU 50 and outputs an ON signal to the system main relay 46 to turn on the power to the power system 30 and turn on the ignition. When the power switch 72 is pressed in this state, the IG signal is output to the HVECU 50 and the off signal is output to the system main relay 46 to cut off the power from the power system 30. The power supply ECU 62 lights up an indicator 73 incorporated in the power switch 72 in order to inform the operator of these states. In the embodiment, the indicator 73 is turned off when the entire vehicle is down (IGOFF), turned off when the accessory is turned on (ACCON), lit green when the ignition is turned on (IGON), turned off when the power system 30 is activated, The system is abnormally blinking orange.

  Further, when the brake switch signal from the brake switch 74 is on, that is, when the operator depresses the brake pedal and the power switch 72 is pressed to input a push signal, the power supply ECU 62 turns on the system main relay 46. When not turned on, an on signal is output to the system main relay 46 and an ignition signal (IG signal) and a start signal (ST signal) are turned on to the HVECU 50 to start the power system 30. The HVECU 50 that has received the ON output of the ST signal turns on the ready signal (RDY signal) indicating that the power system 30 is in an activated state after confirming that the power system 30 is in an activated state. Further, the HVECU 50 outputs the RDY signal to the power supply ECU 62 when the power system 30 is not activated. Further, when the HVECU 50 confirms that the power system 30 is in an inoperable state when confirming that the power system 30 is in an activatable state based on the ON output of the ST signal based on the input, the HVECU 50 activates the power system 30. The off-state of the ready signal (RDY signal) is maintained in order to maintain this state and notify the power supply ECU 62 of this state.

  Next, the operation of the hybrid vehicle 20 of the embodiment configured as described above, particularly the operation from the ACCON state or the IGON state to the start state will be described. As described above, every time the power switch 72 is pressed by the operator and a push signal is input, the state is changed in a toggle shape in the order of the ACCON state, the IGON state, and the IGOFF state. For convenience, the description will be made assuming that the state is the ACCON state or the IGON state. FIG. 2 is a flowchart showing an example of a startup control routine executed by a CPU (not shown) of the power supply ECU 62. This routine is executed when the ACCON state or the IGON state is entered. When the activation control routine is executed, the CPU (not shown) of the power supply ECU 62 first determines the shift position input from the shift position sensor 82 (step S100). In the P position, it is determined whether the brake switch signal input from the brake switch 74 is on and the push signal is input from the power switch 72 (step S110). When the brake switch signal is on and no push signal is input, the processing after step S100 is executed, and when the brake switch signal is on and the push signal is input, system start-up processing is executed ( Step S120). Here, at the time of starting the system, first, the power supply ECU 62 transmits the IG signal and the ST signal to the HVECU 50, and the HVECU 50 receiving these signals performs the starting process of the power system 30 such as checking various sensors. After the execution, the RDY signal is output to the power supply ECU 62. And it is determined whether the starting process of the motive power system 30 was completed (step S130). Here, whether or not the activation has been completed is determined by whether or not the power supply ECU 62 has input the RDY signal described above from the HVECU 50. If the activation is not completed, the activation process is continued in the process of step S120. When the activation is completed, the display panel 90a and the amplifier 89 are controlled so that a message indicating that the activation is completed is notified to the operator. (Step S140). That is, the amplifier 89 is controlled so that a message indicating that the activation is completed from the speaker 89a in the passenger compartment 90 (for example, “system activation is completed”) is notified to the operator by voice, and the message is displayed. The display panel 90a is controlled so as to be displayed.

  In step S100, when the shift position input from the shift position sensor 82 is a shift position to be driven (D position, B position, R position), it is considered that the operator intends to drive and the shift lever 81 is operated. Then, the amplifier 89 is set so that a message prompting the operator to activate the system by operating the power switch 72 by depressing a brake pedal (not shown) after being in the P position is notified to the operator by voice from the speaker 89a in the passenger compartment 90. At the same time, the display panel 90a is controlled so that the message is displayed (step S150). Subsequently, it is determined whether or not the brake signal input from the brake switch 74 is on, that is, whether or not an operator's brake operation has been detected (step S160). When the brake signal is not on, the processing after step S100 is executed. When the brake signal is on, it is considered that the operator intends to drive, and the power system 30 is activated (step S120). It is determined whether or not the activation is completed (step S130). When the activation of the system is completed, a message to that effect is notified to the operator (step S140), and this routine is terminated. As described above, when the shift position sensor 82 detects an operation to the shift position driven by the shift lever 81 of the operator in the ACCON state or the IGON state, the message prompting the operation for setting the power system 30 to the start state. Is notified to the operator by voice and a message on the display panel 90a. Further, when the operation to the position driven by the shift lever 81 is detected, and the brake operation of the operator is detected by the brake switch 74, the power system 30 is activated.

  According to the hybrid vehicle 20 of the above-described embodiment, when the system is in the ACCON state or the IGON state, when the shift position is changed to the D position, the B position, or the R position, the shift lever 81 is operated to operate the P position. After that, the amplifier 89 is controlled so that a message prompting the operator to depress a brake pedal (not shown) and press the power switch 72 to activate the power system 30 is notified from the speaker 89a. In this way, when the shift position is not a shift position that is driven and cannot be driven, for example, when the operator misunderstands that it is in an activated state and changes the shift position to a shift position that drives the shift position, After operating the shift lever 81 to the P position, a message prompting the operator to depress a brake pedal (not shown) and press the power switch 72 to activate the power system 30 is notified to the operator. Therefore, when the power system 30 is not activated and cannot be driven, when the shift position is changed to the shift position driven by the operator's operation, the operator is encouraged to perform the operation for shifting to the activated state. be able to. For this reason, it is possible to suppress the psychological adverse effect of misunderstanding that it may be a failure to the operator.

  When the shift position sensor 82 detects that the shift position is the P position, the brake switch 74 detects the brake operation of the operator, and the power switch 72 is pressed, an instruction to change the power system 30 to the activated state is issued. Enter. As described above, when a plurality of operations such as a shift lever, a brake pedal, and a power switch have to be combined in starting the power system 30, the operation may be insufficient and the power system 30 cannot be activated. Therefore, it is highly meaningful to apply the present invention because the number of cases where the operator misunderstands that the driver is in the activated state and changes the shift position to a shift position that drives the shift position increases. Further, when the shift position is changed to the driving position in the ACCON state or the IGON state, or when the brake operation of the operator is detected by the brake switch 74, the shift lever 81 is operated to the P position. Further, since the amplifier 89 is controlled and the power system 30 is activated so that a message prompting the operator to press the power switch 72 and depressing the power switch 72 to activate the power system 30 is notified to the operator from the speaker 89a, the brake system is activated. If the shift position is changed to a drive position to be driven when the vehicle is operated, the operator is often intended to drive the hybrid vehicle 20, so that the power system 30 is to be activated. Notifying the operator of a prompt message and power If start stem 30 can smoothly transition to hybrid vehicle 20 to the activated state it is possible to notify a message prompting the user to power system 30 and start state to the operator. Then, in the ACCON state or the IGON state, when the operator changes to a shift position that drives the shift position, the operator can be prompted to perform an operation of shifting to the activated state. Also, since the message is notified by voice, as long as the voice can be heard, for example, a message prompting the system to be activated can be transmitted wherever the operator is looking. Still further, when the operator operates the system so that the system is activated, a message indicating that the system is activated is notified to the operator, and therefore the operator is informed that the power system 30 is activated. Can be easily recognized.

  In the hybrid vehicle 20 of the embodiment, the power switch 72 is operated when the brake switch signal from the brake switch 74 is on as a starting operation. However, the power switch 72 is operated regardless of the brake switch signal from the brake switch 74. It may be based on the operation of the switch 72 and another operation (for example, an operation of a parking brake (not shown)). At this time, the content of the message notified to the operator by voice from the speaker 89a is assumed to be the content representing the operation.

  In the hybrid vehicle 20 of the embodiment, the message is notified to the operator by voice from the speaker 89a and the message is displayed to the operator by displaying the message on the display panel 90a installed in the passenger compartment 90. The message may be notified to the operator by one of the speaker 89a and the display panel 90a.

  In the hybrid vehicle 20 of the embodiment, after notifying the operator of the message in the process of step S150 in FIG. 2, it is determined whether or not the brake operation of the operator is detected by the brake switch 74 in the process of step S160. When the operation is detected, the power system 30 is activated in step S120 and the subsequent processing is executed. When the brake operation is not detected, the processing after step S100 is executed. After that, the processing after step S100 may be executed without executing the processing at step S160. Even in this case, when the power system 30 is not activated and cannot be driven, when the shift position is changed to the shift position driven by the operator's operation, the operator is made to perform the operation of shifting to the activated state. Can be urged.

  In the hybrid vehicle 20 of the embodiment, when the shift position is changed while the power system 30 is not activated, the power supply ECU 62 maintains the changed shift position, and notifies the operator in the process of step S150 of FIG. The message to be changed includes the fact that the shift position is changed to the P position. However, when the shift position is changed while the power system 30 is not activated, the power supply ECU 62 does not maintain the changed shift position. Returning to the P position, a message notifying the operator in the process of step S150 in FIG. 2 is a message indicating that the brake operation is performed while the shift position is in the P position and the power switch 72 is pressed, and the shift position is set to the P position. Messages that do not include changes It may be intended to di.

  In the hybrid vehicle 20 of the embodiment, each time the power switch 72 is pressed by the operator, the power switch 72 is a single switch for changing the state in the order of the ACCON state, the IGON state, and the IGOFF state. It does not have to change the state. For example, a plurality of switches corresponding to each state may be provided.

  The hybrid vehicle 20 according to the embodiment includes the HVECU 50 and the power supply ECU 62. However, the hybrid vehicle 20 includes a single electronic control unit, that is, a single unit that combines the functions of the HVECU 50 and the power supply ECU 62 of the embodiment. An electronic control unit may be provided.

  In the embodiment, the power system 30 is a series-parallel hybrid system mainly composed of the engine 32, the planetary gear mechanism 38, the motors 40 and 41, the inverters 42 and 43, the battery 44, the system main relay 46, and the HVECU 50. The system may be configured as any hybrid system other than such a configuration, for example, a series hybrid or a parallel hybrid.

  In the embodiment, the hybrid vehicle 20 including the engine 32, the battery 44, and the motors 40 and 41 has been described. However, an electric vehicle or a fuel cell vehicle that does not include the engine 32 may be used.

  In the embodiment, the power system 30 and the power supply ECU 62 are mounted on a vehicle. However, the power system 30 and the power supply ECU 62 may be mounted on a moving body such as a vehicle other than an automobile, a ship, and an aircraft, or equipment other than a moving body such as a construction machine It may be incorporated as a drive source.

  Here, the correspondence between the main elements of the embodiment and the main elements of the invention described in the column of means for solving the problems will be described. As a correspondence relationship with the drive system of the present invention, in the embodiment, the motor 41 corresponds to the “electric motor”, the configuration excluding the HVECU 50 from the power system 30 corresponds to the “drive device”, and the ACCON state and the IGON state are “preparation”. The shift position sensor 82 corresponds to “shift position detection means”, the power switch 72 and the brake switch 74 correspond to “instruction input means”, and the amplifier 89 and the speaker 89a correspond to “notification means”. When the shift position is changed to the D position, B position or R position when the system is in the ACCON state or the IGON state, the shift lever 81 is operated to the P position and then the brake pedal (not shown) is depressed. Press switch 72 to start power system 30 Power ECU62 the message prompting the user to controls the amplifier 89 to be notified to the operator from the speaker 89a corresponds to a "control device". Further, the power switch 72 corresponds to a “power switch”, and the brake switch 74 corresponds to a “brake operation detecting unit”. Here, the “motor” is not limited to the motor 41 configured as a synchronous generator motor, and may be any type of motor that can input and output power to the drive shaft, such as an induction motor. It doesn't matter. The “shift position detecting means” is not limited to the shift position sensor 82, and any means that detects the shift position may be used.

As long as an instruction to change at least two states, that is, a preparation state in which driving force cannot be output, is input, any method may be used. The “notification unit” is not limited to the amplifier 89 and the speaker 89a, and any unit may be used as long as it can notify a message to the operator. As the “control device”, when the system is in the ACCON state or the IGON state, when the shift position is changed to the D position, the B position or the R position, the brake is not shown after operating the shift lever 81 to the P position. The power supply ECU 62 is not limited to the power supply ECU 62 that controls the amplifier 89 so that a message prompting the operator to depress the pedal and press the power switch 72 to start the power system 30 is notified to the operator from the speaker 89a. When the shift position is changed to the drive position when the system is in a ready state, such as separate electronic control units (for example, the power supply ECU 62 and the HVECU 50), the instruction input means is operated to activate the system. A message prompting As long as it controls the notifying unit so as to be notified to the author may be any ones. The “power switch” is not limited to the power switch 72, and any power switch can be used as long as the operator can change a plurality of states including at least a preparation state in the system and a stop state in which the system is stopped. It does not matter. The “brake operation detecting means” is not limited to the brake switch 74, and any device that detects the brake operation of the operator may be used.
