Description

  The present invention relates to a power supply operation device for a vehicle, and more particularly to a power supply operation device for a vehicle that can improve usability when combined with a keyless authentication system.

  Recently, a so-called keyless entry system in which a door is unlocked when a user is authenticated by communicating between a transmitter carried by the user and a vehicle is becoming more and more common. Various power supply operations such as turning on / off the power supply for accessories, turning on / off the ignition system and power window, and starting the starter motor have become keyless, and these operations can be performed with push buttons. It has come to be offered.

  By the way, in the conventional power operation device using a rotary switch whose rotation is permitted by the matching of the mechanical key, the on / off state of each power supply circuit is switched depending on the rotation position. The user was able to easily understand what state to move to depending on the direction of operation. If it is a push button, providing an individual push button for each function complicates the operation panel. Therefore, it is preferable that a plurality of operations can be performed with a single push button. As a technology to meet such demands, for example, pressing the push button without depressing the brake pedal turns on the accessory power supply, and pressing the push button while depressing the brake pedal activates the starter motor. There is known one configured to control a plurality of states (see Patent Document 1).

However, according to this, there is a problem that it is necessary for the user to determine which state the power supply is currently in, and it is not possible to intuitively determine which state is to be shifted to when the push button is pressed. Therefore, as a technique for solving such inconvenience, there has been proposed a technique in which an illumination means is provided on a push button and the current state is notified in a blinking state (see Patent Document 2).
JP 2003-301664 A JP 2003-254210 A

  However, according to the above-described prior art, after all, if the current state of the power supply circuit is not known, now it is not possible to intuitively determine what the next state will be when the push button is pressed. For example, the first-time user may mistakenly assume that the accessory power supply is also turned off because the engine has stopped, for example, leaving the vehicle, or starting the engine even though he only wants to operate the power window Inconvenience such as could occur.

  The present invention has been devised in order to eliminate such disadvantages of the prior art, and its main purpose is to improve the operability when the power supply circuit is switched by a single push button operation.

  In order to achieve such an object, the present invention provides a power supply operation for an automobile having operation means (operation switch 6) for performing on / off operation of each power supply circuit and engine start operation based on a predetermined condition. In the apparatus, first display means (position display units 23 to 26) for displaying the current state, and second display means (transfer destination display) for displaying a state to be shifted when a predetermined operation by the operator is performed. 27a to 27e).

  According to the present invention, it is possible to visually recognize not only the current state of the power supply circuit but also the state that is shifted when an operation means such as a push button is operated. Can produce various effects.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a configuration of a main part of an automotive power supply control apparatus to which the present invention is applied. This power supply control device is used for accessories such as an ignition system power supply unit 1 that supplies power to an engine ignition device and a fuel supply device, a power system power supply unit 2 that supplies power to a drive motor for a side window and a side mirror, and audio equipment. An accessory system power supply unit 3 that supplies electric power and a starter motor power supply unit 4 that supplies electric power to the starter motor are provided. These are on / off controlled by commands from the electronic control unit 5 that controls the operation of each unit. Is done.

  The electronic control unit 5 has a momentary pushbutton switch 6 that emits an ON signal only when a pressing operation is performed to output an ON / OFF command signal to each power supply unit, and to display an ON / OFF state of each power supply unit. An on signal is issued only when the indicator lamp group 7 attached to the push button switch 6, the brake switch 8 that emits an on signal when the brake petal is depressed, and the selector of the automatic transmission are in the parking or neutral (hereinafter referred to as P / N) range. A P / N switch 9 is connected, and an electric steering lock control unit 10 that controls locking / unlocking of the steering shaft and a portable device 11 held by the user are authorized users by exchanging radio signals. An in-vehicle device 12 of a keyless entry system that performs authentication of whether or not is further connected. The power supply operating device of the present invention is also associated with a vehicle speed signal so that it is effective only when the vehicle is stopped.

  In addition to this, the electronic control unit 5 is connected to a door switch for detecting the opening / closing of the door and an electric door lock control unit for controlling the locking / unlocking of the door. Description of matters that are not relevant is omitted.

  The push button switch 6 for the driver to turn on / off each power supply unit is provided at an appropriate position on the instrument panel so as to surround the operation unit 21 and the periphery of the operation unit 21 as shown in FIG. An annular display region 22 is provided, and the annular display region 22 follows a conventional layout so as not to feel a sense of incongruity with a conventional mechanical key switch, that is, an accessory power circuit is turned on. It consists of a position display section in which characters indicating position (ACC) 23, ignition system and power system power circuit on position (ON) 24, starter motor start position (START) 25, and all circuit off position (OFF) 26 are engraved. An indicator light group 7 is provided. And in the area | region between each position display parts 23-26, the transition destination display parts 27a-27e which consist of an arrow are provided as the indicator lamp group 7 for displaying the transition between these position display parts. .

  Next, the operation procedure of the power supply operating device according to the present invention will be described with reference to FIG.

The state transitioned by the driver pressing the operation unit 21 is divided into the following four states.
1. OFF position: An initial state in which all power supply circuits are turned off.
2. ON position: The ignition system power supply unit 1 and the power system power supply unit 2 are turned on to supply power to the engine ignition device and the fuel supply device, and to operate the side window, the side mirror, and the like. In this state, the starter motor can be started, and the operating state is maintained when the engine is started.
3. ACC: The accessory power supply unit 3 that supplies power to the audio device is turned on.
4). START: The starter motor power supply unit 4 is turned on and the starter motor is started.

  In these four states, it is determined whether the driver is depressing the brake pedal and whether the selector of the automatic transmission is in the P / N range. A transition destination when the operation unit 21 is pressed is selected by associating with a signal or the like.

  When the driver gets into the car, the authorized user authentication process is performed by the keyless entry system. When driving permission is issued, the push button switch 6 incorporated in the electronic control unit 5 and the control circuit of the indicator lamp group 7 are in a standby state. It becomes. In the initial state immediately after the driver enters the vehicle, all the power supply circuits are turned off, and the OFF position 26 of the annular display area 22 is illuminated to indicate the current state.

  In this state (OFF position), when the driver is not depressing the brake petal, the ON position indicates that when the operation unit 21 is pressed, the automatic transmission is switched to the ON position regardless of where the selector of the automatic transmission is located. The arrow 27b toward the screen is illuminated. That is, in the initial state, it can be said that the arrow 27b toward the ON position is always illuminated.

  From this state, when the driver depresses the brake pedal, if the selector of the automatic transmission is in the P / N range, the arrow 27c toward the START position indicating that the engine can be started illuminates and automatically If the transmission selector is in a range other than P / N, all arrows are turned off to indicate that the push button operation is disabled.

  When the power supply circuit is in the OFF position and the selector of the automatic transmission pushes the operation unit 21 in the P / N range and shifts to the ON position, the ON position 24 in the annular region 22 is illuminated. In this state, when the driver does not depress the brake petal, the arrow 27a toward the ACC position indicating that the ACC position is reached when the operation unit 21 is pressed is illuminated regardless of the range of the selector of the automatic transmission. To do.

  On the other hand, when the driver depresses the brake pedal in the ON position, if the selector of the automatic transmission is in the P / N range, the arrow 27c toward the START position indicating that the engine can be started is illuminated, If the selector of the automatic transmission is in a range other than P / N, all the arrows are turned off to indicate that the push button operation is invalid.

  When the driver depresses the brake petal at the ON position and presses the operation unit 21 to shift to the ACC position, the ACC position 23 of the annular display area 22 is illuminated. When the driver does not depress the brake petal in this state (ACC position), only when the selector of the automatic transmission is in the P range, when the operation unit 21 is pressed, the OFF position is indicated. The arrow 27d is illuminated. On the other hand, when the selector of the automatic transmission is outside the P range, all the arrows are turned off to indicate that the push button operation is invalid.

  When the driver depresses the brake pedal at the ACC position, if the selector of the automatic transmission is in the P / N range, the arrow 27c toward the START position indicating that the engine can be started is illuminated, and P / If the range is other than N, all the arrows are turned off to indicate that the push button operation is invalid.

  After the driver depresses the brake pedal at the ACC position and presses the operation unit 21 to start the engine (during engine operation), the selector of the automatic transmission is used regardless of whether or not the driver depresses the brake petal. Only in the P range, the arrow 27d toward the OFF position indicating that the operation section 21 is pressed to enter the OFF position is illuminated. On the other hand, when the selector of the automatic transmission is other than the P range, the arrow 27a toward the ACC position indicating that the ACC position is reached when the operation unit 21 is pressed is illuminated. In any case, when the engine is in operation and is stopped, pressing the operation unit 21 stops the engine.

  As described above, when the driver depresses the operation unit 21 without stepping on the brake pedal when the selector of the automatic transmission is in the P / N range, the transition is made sequentially from OFF to ON to ACC to OFF, which is inadvertent. Even if the operation unit 21 is pressed, there is no fear of starting the engine, and it is possible to satisfy the desire to operate the power window without starting the engine or to listen to the radio while the vehicle is stopped. Furthermore, if an alarm is sounded when the door is opened at the ON position and the ACC position, it is possible to prevent the vehicle from getting off without being in the OFF position.

It is a block diagram which shows the principal part structure of the motor vehicle power supply control apparatus with which this invention is applied. It is a front view of the pushbutton switch by this invention. It is explanatory drawing of the transition of a display.
