Description

TECHNICAL FIELD The present invention relates to an in-vehicle device operation control device that controls whether or not an operation input of an in-vehicle device can be accepted depending on whether a stop state of a vehicle is detected.

Conventional technology Conventionally, in-vehicle devices such as a vehicle guidance device that displays the current position of the vehicle on a screen on which a road map is projected, the operation input can be received only when the vehicle is stopped, and the vehicle travels. Operation control is performed such that the input command is not accepted from time to time, and when the vehicle runs in the middle of a series of operation inputs at the time of stop, the input command up to that time is invalidated.

However, in such conventional operation control of in-vehicle devices,
If the vehicle enters the running state before completing a series of operation input of the on-board equipment when stopping the vehicle, there is an annoyance that the operation input must be restarted from the beginning when the vehicle stops thereafter It has become.

Purpose The present invention has been made in consideration of the above points, and enables the operation input in the vehicle-mounted device to be accepted only when the vehicle is in a stopped state, and the operation input when not accepting the operation input otherwise. Provided is an on-vehicle device operation control device that enables an input operation at that time to be continuously performed when a vehicle comes out of a stopped state during input, thereby improving operability of the on-vehicle device. Is what you do.

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

FIG. 1 shows an example of the configuration of a vehicle guidance device, in which a speed sensor 1 for detecting a running speed of a vehicle, a direction sensor 2 for detecting a traveling direction of the vehicle, and a running speed detected by the speed sensor 1 are shown. The traveling distance of the vehicle is measured by integrating over time, and the X-direction for each unit traveling distance of the vehicle is determined from the traveling direction of the vehicle detected by the direction sensor 2.
An arithmetic control unit 3 composed of, for example, a microcomputer, which obtains the current position on the Y coordinate by sequential calculation and centrally controls the entire apparatus, and the arithmetic control unit 3
A travel locus storage unit 4 for sequentially storing data of the current position on the XY coordinates, which changes momentarily according to the travel of the vehicle, and stores and stores the data as finite continuous position information of the vehicle; , A map information storage medium 5 storing information on the road map, a storage medium reproducing unit 6 for selectively reading road map information from the storage medium 5, and a predetermined road map based on the read map information. A display section 7 for displaying the current position of the vehicle on the road map projected on the screen, along with the traveling locus and the traveling direction of the vehicle at the current position, as necessary, along with the traveling of the vehicle. , An operation command to the arithmetic and control unit 3 and selection and designation of a map to be displayed on the display unit 7, and a starting point and a destination of the vehicle on the displayed map. Make settings and selectively give display commands such as travel trajectory, change the direction of the displayed map and travel trajectory, shift the display position, partially enlarge the map and travel trajectory, select the display scale, etc. Operation unit 8 that can appropriately change the setting of the display mode of
And is constituted by.

With such a configuration, the map information storage medium 5
Is read out on the screen of the display unit 7 and the XY is set in accordance with the map scale set in advance by the arithmetic and control unit 3 according to the traveling of the vehicle from the starting point set on the map. The current position on the coordinates is obtained by calculation every moment, and the calculation result is sequentially sent to the traveling locus storage unit 4 to update the stored contents, and the stored contents are constantly read and displayed on the display unit 7.
Sent to

As a result, for example, as shown in FIG. 2, a display mark M1 indicating the current position of the vehicle is displayed on the map displayed on the screen, and a display mark indicating the traveling direction of the vehicle at the current position. A display mark M3 of the traveling locus from M2 and the starting point ST to the current position is simulated following the traveling state of the vehicle.

In the present invention, in such a vehicle guidance device, the arithmetic control unit 3 detects that the vehicle is in a stopped state by detecting that the traveling speed of the vehicle detected by the speed sensor 1 is zero. Means for receiving an operation input from the operation unit 8 only when the vehicle is stopped, and stopping the vehicle during the input operation of the operation unit 8 when the vehicle is detected to be stopped. When the vehicle comes out of the state and enters the running state, means for continuously accepting the operation input until the input operation at that time is completed is taken.

At that time, the arithmetic control unit 3 does not accept any operation input from the operation unit 8 when the vehicle is in a running state, and also, for example, changes the setting of the destination on the map or displays the destination on the map. The operation input from the operation unit 8 may not be selectively received when the vehicle is in the traveling state, only for the operation input related to the screen operation such as the enlargement of the map.

For example, when the destination is to be changed, the user presses the cancel key for the destination and then operates the up, down, left and right scroll keys to scroll the map displayed on the screen to the new destination. Is searched, the searched destination is positioned by specifying the cursor, and a series of input operations in the operation unit 8 of pressing the destination setting key are completed.

In the present invention, when such a destination setting change is performed, if the destination cancel key is pressed when the vehicle is stopped, the arithmetic control unit 3 changes the destination setting by a predetermined series of input operations. Even if the vehicle enters the running state during a series of input operations at that time, each operation input until the destination setting key is finally pressed is valid. , So that the reception is continued.

Therefore, according to the present invention, even if the vehicle runs in the middle of a series of input operations when the vehicle stops, the operation input up to that point is invalidated, and the input operation is performed again when the vehicle stops thereafter. Is eliminated from the beginning, and the predetermined input operation can be completed quickly with good operability.

Also, in the present invention, when the vehicle enters a running state while performing a series of input operations, each operation input is not received unlimitedly until the series of input operations at that time is completed. Operation input is continuously accepted only for a predetermined number of times, for example, only once, so that the input operation in the running state of the vehicle is not performed many times. .

For example, when the destination setting is changed, if the vehicle has run in the middle of the input operation at the stage of positioning the destination by specifying the cursor, when the last destination setting key is pressed Only the input operation of is valid.

FIG. 3 shows a control flow in the arithmetic control unit 3 at that time.

Further, according to the present invention, when the vehicle enters a running state while performing a predetermined input operation, the operation input is not received indefinitely until the input operation is completed. 3, the operation input at that time is continuously performed only for a time set in advance by a timer provided in the inside of the vehicle 3 so that the input operation in the running state of the vehicle is performed for a long time. I try not to.

In the case where the means for restricting the reception of the operation input based on the timer set time is employed, the reception of the continuous operation input is effective only when a series of input operations is completed in a short time. In a case where the vehicle is in a running state at the beginning of a series of input operations and it takes time to perform several operation inputs until the input operation is completed, for example, when the setting of the destination is changed, If the vehicle enters the running state just by pressing the cancel key, the reception of the remaining operation input is not completed within the timer set time, and the input operation at that time is invalidated.

As described above, according to the present invention, the input means for inputting the operation signal for operating the on-vehicle equipment, the vehicle stop state detecting means for detecting that the vehicle is in the stop state, and the vehicle stop state are detected. The operation control means comprises an operation validating means for validating the operation input when the vehicle is running, and an operation invalidating means for invalidating the operation input when the vehicle is running. When the vehicle is in a state, an operation continuation unit that makes the operation input valid for a predetermined period is provided. It is possible to improve the operability of the vehicle while restricting the input operation of the vehicle-mounted device when the vehicle deviates from the stop state. It has the great advantage of being able to.
