Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a switch control device for a vehicle equipped with various switches for automatically opening/closing a trunk opener, a sunroof, etc. installed in an automobile, and further relates to More specifically, the present invention relates to a switch control device that regulates switch input depending on whether the vehicle is stopped or running.

(B) Background of the Invention Normally, this type of switch control device has a required number of operation switches for various devices mounted on the instrument panel at the front of the vehicle interior, in order to improve the operability and make the vehicle more sophisticated.

However, among the various operation switches, the stop mode switch, which can be operated only when the vehicle is stopped, and the drive mode switch, which can be operated even while the vehicle is running, are located on the instrument panel. When operating the switch while driving, it is easy to be confused about which switch to select, reducing the operability of the switch.

This is dangerous because it can lead to erroneous operations such as operating a stop mode switch for a trunk opener or the like even when the vehicle is running.

(c) Purpose of the Invention Therefore, the present invention divides the switch operation modes of various devices into a stop mode and a running mode that can be operated while the vehicle is stopped and while the vehicle is running, and separates the device types according to each switch operation mode. Display on screen,
By inputting the operation switch in response to this display, inappropriate input operations such as operating the operation switch in stop mode while driving are restricted, increasing safety and improving the operability of the operation switch. The purpose of this invention is to provide a vehicle switch control device that improves vehicle performance.

(D) Summary of the Invention This invention divides the switch operation modes of various devices into a stop mode and a running mode that can be operated while the vehicle is stopped and while the vehicle is running. The present invention is characterized by a switch control device for a vehicle in which a screen display device for displaying equipment types for each switch operation mode is stacked and integrated on top of the operation switch.

(E) Effects of the Invention According to the present invention, since the switch operation mode of the device can be switched between when the vehicle is stopped and when the vehicle is running, it is possible to avoid accidentally operating a trunk opener, etc., which would be dangerous if operated while the vehicle is running. It is extremely safe.

Furthermore, since one operation switch has two functions: stop mode and running mode, the number of operation switches can be reduced by half, and the screen display and operation switch are stacked vertically to form a pair. Therefore, it is possible to save space, facilitate wiring, and improve visibility and operability.

a, 24a, 24a are inserted into the terminal holes 39 of the printed circuit board 2 in FIG. 1 and soldered.

Figure 5 shows the control circuit block diagram, and shows the CPU41
controls each circuit device according to a program stored in the memory 42, and a wheel rotation detection section 43 detects whether the wheels of the vehicle are stopped or rotating, and a stop/running determination section 44 determines this.

The operating state of the automobile switch control device constructed as described above will be explained with reference to FIG.

First, when the car is in a stopped state and the key is put into the car in the first step and the power is turned on in the first step 51, in the second step 52, the stopped/running state of the car is determined by the stop/running determining section 44. If it is determined in the third step 53 that the vehicle is in the stopped state, the mode display LED 7 lights up to indicate that the vehicle is in the stop mode, and the screen display of each push button unit 5 also lights up. 4a, graphics of various types of equipment corresponding to this stop mode are displayed on the screen as shown in FIG.

Then, in a fourth step 54, a desired push button unit 5 on which the figures of these display items are displayed is pressed.

In this case, if the desired mode is not displayed, in a fifth step 55, the mode changeover switch 6 is switched to change to the running mode shown in FIG. 8. Then press the pushbutton unit 5 in which the desired mode, for example trunk opener, is displayed.
When pressed, the trunk is automatically opened when the appropriate input mode is determined in the sixth step 56, and the operation indicator LED 8 lights up, and also flashes and flickers while the trunk is opened. . This allows you to confirm the input operation and the operation at the same time.

Then, in the seventh step 57, the trunk is closed, and in the eighth step 58, the operation display LED 8 is turned off, and in the ninth step 59, the input operation for the trunk opener is completed. Also, the 10th step 60
If you want to continue operating the next mode, you just need to input the same operation switch, and then turn off the power by turning off the key.

Next, in the running state of the car, it is determined in the second step 52 that the car is running, and then in the eleventh step 61.
Based on the driving determination signal, the driving mode display mark is lit up on the LED 7, and the screen display 4a displays the graphics of the driving mode equipment items shown in FIG. 8 on the screen.

When the push button unit 5 on which the driving mode is displayed is pressed, a sunroof or the like is automatically opened/closed based on the pressing signal, and the LED 8 indicating the pressed operation is lit.
This allows you to confirm the input operation you pressed. If the vehicle stops during automatic operation, for example while waiting at a traffic light at an intersection, the mode will be switched to stop mode after the operation is complete.

By the way, if you start driving with the trunk opener etc. left open while the vehicle is stopped, at step 57,
The mode is determined to be unsuitable and the twelfth step 62
Then, the stop mode is displayed on the screen display 4a, and in the 13th step 63, the operation display LED 8 starts flashing to warn the driver that he has forgotten to close the trunk.

Furthermore, when operating the driving mode while the vehicle is stopped, the mode changeover switch 6 can be pressed to switch to the driving mode. Note that even if the mode change switch 6 is pressed while the vehicle is running, the mode will not change.

As described above, the display mode switches between when the vehicle is stopped and when the vehicle is running, so there is no need to worry about accidentally operating the switch while the vehicle is running, which could be dangerous. It is also expected to have a significant effect on safety by providing warnings to drivers.

Furthermore, by switching the display mode, multiple functions can be provided with a single operation switch, which can be expected to be very effective in terms of space saving.

In the embodiment, the LED 8 has an operation display and a flicker function, but the screen display 4a may have the function as shown in FIGS. 7 and 8.

Also, although an LCD is shown as an example of a screen display,
You may also bring a fluorescent display tube, CRT, etc.
