When information that the shift position is in a shift position other than a parking range is received from the shift position information acquiring part 2, and information that the ignition power supply is changed from on to off is received from the ignition power on-off information acquiring part 3, the controller 6 causes the display means 7 to display information prompting a driver to change the shift position to the parking range.

Description

  The present invention relates to a power-off induction device and a program for inducing power-off to a user.

Conventionally, in order to stop an engine of a vehicle, a system is known in which the engine is stopped by operating a push start button provided in the vehicle.
When the engine is operating with the vehicle stopped, for example, when the shift position is set to the P range (parking range) and the push start button is pressed, the ignition power supply (IG power supply) and the accessory power supply (ACC power supply) are turned off.

  In addition, when the engine is running with the vehicle stopped, pressing the push start button at a shift position other than the parking range (for example, D (drive) range, N (neutral) range) turns off the ignition power and stops the engine. However, the accessory power supply is kept on (see, for example, Patent Document 1).

  The ignition power source is a power source that mainly supplies power to an electrical component (for example, a vehicle speedometer driving device) related to engine driving, and the accessory power source is an electrical component other than the electrical component mainly related to engine driving (for example, an audio device). Etc.). The reason why the power supply is divided into the accessory power supply and the ignition power supply is that the electrical components that operate by supplying power from the accessory power supply operate independently of the operation of the engine, while they operate by supplying power from the ignition power supply. This is because the electrical component operates in connection with the operation of the engine, and the electrical component that operates by supplying power from the accessory power supply may be used even when the engine is not operating.

  Here, when the push start button is pressed at a shift position other than the P range, the engine itself stops. Therefore, the user may get off without performing any operation without noticing that the accessory power source is still on. In this case, since the electrical components that operate by supplying power from the accessory power supply are also kept on, the in-vehicle battery continues to be discharged, and if this state continues for a long time, the in-vehicle battery is completely discharged.

  Conventionally, in order to solve such problems, there is a technology for notifying the user of an abnormality with a warning sound when the door is opened without any operation after the engine is stopped by pressing the push start button at a shift position other than the P range. Proposed.

JP 2009-79477 A

  However, in the proposed technique, even if the user notices a warning sound that sounds when the door is opened, if the user does not know how to deal with the warning sound, the user is confused and does not perform any operation. There is a risk of leaving the vehicle. In this case, the on-board battery continues to be discharged because the electrical components that operate by supplying power from the accessory power supply are still on, and the battery may be completely discharged depending on how long the user is away from the vehicle. is there.

  This invention is made | formed in view of such a problem, and it aims at suppressing the discharge which the vehicle-mounted battery does not intend.

  A power-off induction device according to the present invention made to achieve such an object includes an ignition power on / off information acquisition means for acquiring ignition power on / off information, a shift position information acquisition means for acquiring shift position information, After the information indicating that the shift position is a shift position other than the parking range is received from the shift position information acquisition means, or in the state of being received, the ignition power supply changes from on to off from the ignition power on / off information acquisition means. The control means for notifying the user of the information for prompting the user to inform the user of the information indicating that the shift position is set to the parking range is received.

  According to the above configuration, when the user presses the push start button at a shift position other than the P range while the engine is operating in the state before getting off, the user needs to set the shift position to the parking range at the stage before getting off. Since it can be noticed, the user can predict the subsequent power-off operation.

  Further, the control means informs the notifying means of information for prompting an operation for turning off the accessory power supply together with the information after notifying information for prompting the shift position to be in the parking range. (Claim 2).

  Therefore, after prompting the user to shift the shift position to the parking range or at the same time as prompting the user to turn off the accessory power, the user can be surely predicted the subsequent power-off operation. .

  Further, the control means turns off the accessory power supply when information indicating that the shift position is in the parking range is detected after information indicating that the shift position is in the parking range is notified. The information may be notified to the notification means and the accessory power supply may be turned off.

  Therefore, after prompting the user to set the shift position to the parking range, the accessory power is turned off when the shift position becomes the parking range due to the user's operation or the like and the shift position information is detected. Since the information is guided to the user and the accessory power supply is turned off, unintended discharge of the in-vehicle battery can be suppressed.

  Further, when the control means receives the instruction information for instructing the shift position from the user sent through the operation unit to be in a parking range when the information is notified from the notification means, Controls the position to be in the parking range and informs the informing means that the accessory power is turned off, and turns off the accessory power from the user sent via the operation unit. When the instruction information is received, the accessory power supply is turned off.

  Therefore, the information that prompts the user to turn off the accessory power supply when the shift position is changed to the parking range based on the instruction information from the operation unit (user) that is sent in response to the information that prompts the shift position to be in the parking range. Since the accessory power supply is turned off based on the instruction information from the operation unit (user) that is received and received, the steps until the user reliably turns off the accessory power supply (parking range change instruction, accessory power-off instruction) It can be stepped on and the unintended discharge of the in-vehicle battery can be reliably suppressed.

  Further, the function as the control means of the power-off induction device described above may be realized by a program (claim 5). If such a program is executed by a computer built in the power-off induction device, the power-off induction device has the same operations and effects as the power-off induction device of the present invention described above. Further, the program can be distributed using a network or the like, and the replacement of the program in the power-off induction device is easier than the replacement of the parts. Therefore, it is possible to easily improve the function of the power-off induction device.

An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a diagram illustrating a configuration of a power-off induction device 1 according to an embodiment of the present invention.
Specifically, as shown in FIG. 1, the power-off induction device 1 includes a shift position information acquisition unit 2, an ignition power on / off information acquisition unit 3, an accessory power on / off information acquisition unit 4, an instruction information acquisition unit 5, and a control unit. 6.

  The shift position information acquisition unit 2 is connected to the control unit 6 and the shift operation unit 9 and acquires shift position information from the shift operation unit 9. This shift position information is parking range (P range) information and range information other than the P range. The ranges other than the P range include reverse (R), neutral (N), drive (D), second (2), Each range of low (L) is mentioned.

  The shift operation unit 9 includes a parking range (P range) switch (not shown) and a switch (not shown) of a range other than the P range. These switches have a function of detecting the state of the shift position selected by the user and transmitting shift position information indicating the state of the detected shift position.

  In addition, regarding the power-off control of the present embodiment, since it is important whether the range position is the P range or a range other than the P range as described later, the distinction between the two (the P range and the other ranges) is important. I will only do it.

  The ignition power on / off information acquisition unit 3 and the accessory power on / off information acquisition unit 4 are connected to an ignition (IG) power relay (ignition power) 11 and an accessory (ACC) power relay (accessory power) 12 via a power controller 14, respectively. Yes. The ignition power supply relay 11 and the accessory power supply relay 12 are connected to the vehicle battery. Connected to the power supply controller 14 is a push start switch 10 for sending instruction information from the user including an instruction to start and stop driving the engine.

  The ignition power relay 11 is a relay for supplying power to on-vehicle electrical components related to engine driving. Moreover, the accessory power supply relay 12 is a relay for supplying a power supply to the vehicle-mounted electrical equipments other than an engine drive.

  When the ignition power supply relay 11 is turned on by the control signal from the power supply controller 14 (the ignition power supply is turned on), power is supplied from the vehicle battery via the ignition power supply relay 11, and the electric equipment connected to the ignition power supply relay 11 is connected. The product becomes operational.

  When the accessory power supply relay 12 is turned on by the control signal from the power supply controller 14 (the accessory power supply is turned on), power is supplied from the vehicle battery via the accessory power supply relay 12, and the electrical equipment connected to the accessory power supply relay 12 is connected. Becomes operational.

  The ignition power relay 11 sends ignition power on / off information (on signal (high level signal)) indicating that the ignition power is on when the ignition power relay 11 is on, and the ignition power relay 11 is turned off. If the ignition power supply 11 is off, ignition power supply on / off information (off signal (low level signal)) indicating that the ignition power supply 11 is in an off state is transmitted.

  The accessory power relay 12 sends accessory power on / off information (on signal (high level signal)) indicating that the accessory power is on when the accessory power relay 12 is on, and the accessory power relay 12 is turned off. When the power is on, accessory power on / off information (off signal (low level signal)) indicating that the accessory power is off is sent.

The ignition power on / off information acquisition unit 3 acquires ignition power on / off information from the ignition power relay 11 via the push start switch 10.
The accessory power on / off information acquisition unit 4 acquires accessory power on / off information from the accessory power relay 12 via the push start switch 10.

  The instruction information acquisition unit 5 is connected to the operation switch 13 and acquires instruction information from the operation switch 13. The instruction information is information instructed by the user with respect to information notified on the display unit 7 or the like. Specific contents will be described later.

Here, the operation switch 13 is a mechanical key switch provided around the meter panel, and examples thereof include a steering switch and a tilt commander switch.
The control unit 6 is connected to the shift position information acquisition unit 2, ignition power on / off information acquisition unit 3, accessory power on / off information acquisition unit 4, instruction information acquisition unit 5, display unit 7, and audio output unit 8.

  The control unit 6 is mainly composed of a well-known microcomputer including a well-known CPU, ROM, RAM, I / O (not shown) and a bus line connecting these components, and the control stored in the ROM and RAM. Processing described later is executed based on the program.

  The display unit 7 is a display device that is provided in a part of a meter panel (not shown) and displays predetermined character information to be described later based on a display control signal output from the control unit 6, specifically a liquid crystal display, There are organic EL displays, and any of them may be used. The display unit 7 may be provided in a place (for example, a dashboard) other than the meter panel as long as it is easy to see for the driver.

  The voice output unit 8 is a voice output device that outputs predetermined voice information (for example, voice guidance data) to be described later based on a voice output control signal output from the control unit 6, and specifically includes a speaker or the like. It is done.

The predetermined character information and the predetermined voice information are stored in advance in the ROM or RAM in the control unit 6.
Hereinafter, a power-off induction process executed by the control unit 6 of the power-off induction device 1 according to the embodiment of the present invention will be described with reference to FIGS. 2 and 3. Note that the display control process of the display unit 7 and the audio output control process of the audio output unit 8 are well-known processes, and thus description thereof is omitted.

When this process starts, first, it is determined whether or not the shift position information sent from the shift position information acquisition unit 2 is a shift position other than the P range (S101).
If it is determined that the shift position information is a shift position other than the P range (Yes in S101), it is determined whether or not the ignition power has changed from on to off (S102). If it is determined that the shift position information is in the P range (No in S101), the process returns to S101.

  Detection of the change of the ignition power supply 11 from on to off is performed by the ignition power supply on / off information acquisition unit 3 monitoring the ignition power supply on / off information and detecting a change from a high level signal to a low level signal.

  If it is determined that the ignition power supply 11 has changed from on to off (Yes in S102), information indicating that the accessory power supply 12 is not off is displayed on the display unit 7 as character information (S103). Information indicating that the accessory power supply 12 is not off may be output from the voice output unit 8 as voice information (voice guidance). When it is determined that the ignition power supply 11 has not changed from on to off (No in S102), the power-off induction process ends.

  Thereafter, information for prompting the user to set the shift position to the P range is displayed on the display unit 7 as character information (S104). Information that prompts the user to switch to the P range may be output from the voice output unit 8 as voice information (voice guidance).

  Here, the information that the accessory power supply 12 is not off and the information that prompts the user to set the shift position to the P range may be displayed simultaneously as shown in FIG. 3A, for example. The information indicating that the user is prompted to shift the shift position to the P range may be displayed after the information indicating that the accessory power source 12 is not off is displayed.

  Also, as shown in FIG. 3 (b), the user is made a suggestion “Would you like to set the shift position to the P range?”, And if “Yes” is answered, the shift position is set to the P range. The shift operation unit 9 may be controlled as follows.

  Note that the control of the shift operation unit 9 is specifically sent from the control unit 6 to a mission ECU (not shown) that controls the transmission system, a command (shift drive control signal) for setting the shift position to the P range. The mission ECU controls the shift operation unit 9 based on the shift drive control signal and sets the shift position to the P range.

  Therefore, in the above-described processes from S101 to S104, when the user presses the push start button 10 at a shift position other than the P range after the engine is stopped, the accessory power supply 12 is in an on state for the user before getting off. And that the shift position needs to be in the parking range, the subsequent power-off operation can be predicted by the user.

  In the determination of S101, when information indicating that the shift position is a range other than the P range is currently received, the process proceeds to S102, but information indicating that the shift position is a shift position other than the P range is present. In consideration of an environment that is not always output, for example, when the information is transmitted via the in-vehicle LAN, the shift position is in the P range after receiving information that the shift position is in a range other than the P range. Even in a state before receiving the information, the process of S102 may be performed.

  Thereafter, it is determined whether or not the shift position information sent from the shift position information acquisition unit 2 is a shift position in the P range (S105). When it is determined that the shift position information is the shift position of the P range (Yes in S105), information indicating that the accessory power supply is turned off is displayed on the display unit 7 as character information (S106). Information indicating that the accessory power supply should be turned off may be output from the voice output unit 8 as voice information (voice guidance).

Here, information indicating that the accessory power supply should be turned off is displayed, for example, as shown in FIG.
Information indicating that the accessory power supply 12 is to be turned off is displayed as character information on the display unit 7 (S106), and then the accessory power supply 12 is forcibly turned off after a predetermined time has elapsed (S107), and this process ends. . In addition, after displaying on the display unit 7 information indicating that the accessory power supply 12 is to be turned off, the accessory power supply 12 may be turned off by the user without performing the operation of forcibly turning off the accessory power supply 12.

If it is determined that the shift position information is a shift position other than the P range (No in S105), the process returns to step 104.
Therefore, since the user is prompted to turn off the accessory power supply 12 and the accessory power supply 12 is forcibly turned off, unintended discharge of the in-vehicle battery can be reliably suppressed.

(Modification 1)
After the information that prompts the shift position to be in the parking range is notified (S104), the control unit 6 displays the information that prompts the accessory power supply 12 to be turned off without performing the process of S105. 7 or may be output to the audio output unit 8 (S106). Further, the process may be left to the user without performing the process of S107.

  Since it is determined in S102 that the ignition power supply 11 has changed from on to off, it is estimated that the user has an intention to turn off the accessory power supply 12, and the process of S105 (proposed to the user to set the shift position to the P range) And the user himself / herself is urged to turn off the accessory power supply 12 without performing the process of S107, and the user himself / herself changes the shift position to the P range based on the information of S104 and S106 to turn off the accessory power supply 12. This is because it is expected to be performed.

(Modification 2)
Steps S201 to S204 in the power-off induction process according to Modification 2 are the same as the processes from S101 to S104 in the above-described embodiment as shown in FIG. Therefore, the description of the processing of S201 to 204 is omitted, and the processing of S205 to 209 will be described.

  The second modification suggests that the shift position is set to the P range for the user, suggests that the accessory power supply be turned off, and asks the user to select either “Yes” or “No”. Let me choose. On the other hand, in the above embodiment, such a selection is not performed and the two are different in this respect.

  In S204, information (see FIG. 3B) for prompting the shift position to be in the P range is displayed on the display unit 7, and a suggestion to the user is “Would the shift position be in the P range”? Do. If the user selects “Yes”, the information indicating the P range is confirmed (Yes in S205), and then the shift position is changed to the P range (S206). When the user selects “No”, the user's intention (the shift position is not desired to be in the P range) is respected and this control is terminated.

  After the shift position is changed to the P range (S206), information for prompting the accessory power supply to be turned off is displayed on the display unit 7 as character information (S207). Information indicating that the accessory power supply 12 should be turned off may be output from the voice output unit 8 as voice information (voice guidance).

  Here, information for prompting the accessory power supply 12 to be turned off is displayed, for example, as shown in FIG. In this modification, a process for turning off the accessory power supply 12 is proposed to the user.

  Information that prompts the user to turn off the accessory power supply 12 is displayed on the display unit 7 as character information (S207), and the user says "Shift position is P. Do you want to turn off the accessory power supply?" Make a suggestion. When the user selects “Yes”, the information for instructing the accessory power supply to be turned off is confirmed (Yes in S208), the accessory power supply 12 is turned off (S209), and the process ends. When the user selects “No”, the user's intention (does not want to turn off the accessory power supply) is respected and this control is terminated.

  Therefore, based on the instruction information from the operation unit (user) for the information prompting the shift position to be in the parking range, the shift position is automatically changed to the parking range, and the operation for the information prompting to turn off the accessory power supply. Since the accessory power supply is turned off based on the instruction information from the user (user), the user can be surely taken through the steps until the accessory power supply is turned off, and the unintended discharge of the in-vehicle battery is reliably suppressed. can do.

  Here, in this embodiment, the shift position information acquisition unit 2 corresponds to the shift position information acquisition means of claim 1 of the present invention, and the ignition power on / off information acquisition unit 3 acquires the ignition power on / off information of claim 1 of the present invention. The control unit 6 corresponds to the control unit of claim 1 of the present invention, the display unit 7 and the audio output unit 8 correspond to the notification unit of the present invention of claim 1, and the operation switch 13 corresponds to the present invention. 4 corresponds to the operation unit.
