Next, in step 2570, the direction of the vehicle from the running point to fh destination (D direction ef6=m (DX/DY) is calculated, and in step 2580, the direction to the destination with respect to the running point is calculated based on which of the 16 directions corresponds to DH is determined. Then, in step 2590, the relative direction DR to the destination with respect to the traveling direction of the vehicle is calculated (DH=DR+DAo).

FIG. 10 shows detailed arithmetic processing of the next key data manual μm processing 1400. Jin's key data Human-powered μm Chin 1400 will not explain the arithmetic processing in each step, but the process from destination setting unit 3 to the first destination and second destination will be omitted. Input and memorize east-west and north-south distance data of NAVl,l
In response to the input operation of the key 351°NAVl and the 2 key 352, calculation operations for the first destination and the second destination are selected and started. In addition, the operation operations of the main names in this operation and calculation process will be explained. ■Switching to input mode, switching the display to data input display and generating a signal that lights up all LEDs 341 to 344 in destination setting section 3, ■Error mode - displaying error display (EEE) and searching for input data O; ■Set fade - Replace the new input data with the old data and switch to the initial straight line distance display L in the destination setting section 3

■ Error determination - Input the same or opposite direction, input only the direction (do not input the distance), or the initial straight line distance is Om, ■ Input the direction and distance After inputting one direction key manually, the destination setting section 3 The direction key generates a signal that lights up the LED in response to manual input, and the number keys accept manual input.Allows input from any digit.If the upper digit is input and no number is set in the lower digit, the lower digit ON display. Nao, NAVl, 1. To switch the NA41.20 operation, for example, when switching the operation to NAV1,2 during the NAV1,1 operation, turn on the NAV1, 2 key, 352.5 TART key 33, respectively.

After this key data human power μm control 1400, the process proceeds to a display routine 1500, where the information exchange μm control 1300 inputs various data from the 98-pin F microphone p computer 4 to determine vehicle traveling direction, relative direction to the destination, and straight line distance. , displays various display signals to display each achievement level! l! Occurs on 6th.

Further, detailed calculation processing of the next pulse motor drive routine 1600 is shown in FIG. In this pulse motor drive routine 1'' 600, it is first determined in step 1601 whether or not the ACC signal is generated from the Ace detection circuit 18, and when the AOC signal is not generated, the process proceeds to step 1602; The value of the 91st internal timer that first arrived is stored, and the elapsed time is determined by comparing this memorized 9th internal timer value with the current internal timer value, and the process proceeds to step 1i03 to determine the elapsed time. (The time is 30 seconds) Determine whether it is short or not.

If it is shorter than 30 seconds, set FTIME to 1 in step 1604.
If the time is 30 seconds or more, set FTI in step 16o5.
Set ME to 0.

9. If it is determined in step 1601 that the ACC signal is generated, the process proceeds to step 1606, and the FTI
Determine whether ME is set to OK. At this time, if more than 30 seconds have passed since the ACC signal stopped being generated until the ACC signal is generated, the value of FTIME is 0.
If so, the process advances to step 1607, and the pulse image 11 is
The rounding FPOS for initial positioning of a is set to 0, the process proceeds to step 1608, and since the FPOS is 0, the process branches to step 1609. In this step 1609, an l pulse signal is generated to rotate the pulse motor l& in the right direction, and the pulse motor position detector 11
It is determined whether the pulse motor lla has come to the reference position (θ°) based on the signal G (low level, high level No. 1 according to each phase as shown in FIG. 12) from G.

Then, this step 160 is performed until the rice reaches the reference position.
1 pulse signal is generated every time 9 arrives. And In! of low level μ! t; # continuous*4Lm (including detection of high level ~ → low level) When a high level y get occurs after 9 days, it recognizes that the bus motor la has come to the reference position, and then changes the vehicle's direction. The pulse motor 1a is rotated one step at a time to the right to the position corresponding to the data. Then, when the number of one-pulse signal signals necessary to drive the pulse motor 1-a to the position corresponding to the vehicle traveling direction data is completed, the determination in step 1610 is YF.

.

Sf: Set to l. Therefore, after this step 1
When reaching 608, the process branches to step 1612. In this step 1612, a pulse signal for driving the pulse motor 1st C is generated according to data on the vehicle traveling direction, and low and high CM signals from the 8-pulse motor position detection section 110 are generated.
The position of O@, 90@, 180", or 270@ is detected depending on the number of numbers, and this detected position is compared with the data of the heading of the vehicle to control the pulse motor 1a. Adjust to the position that matches the data. (According to the comparison result, drive by l steps more or less.) On the other hand, the elapsed time from when the ACC signal stops being generated until it starts occurring again is less than 30 seconds. Short and FTIM
If the value of E is 1, when the Stellar step 1606 is reached, the process does not proceed to step 1607 but proceeds to step 1608. Then, if FPO8 is set to 1 by then, it will proceed to Stella 7"l 612. Therefore, even if the key switch is turned off once and then turned on again, the time interval will be 30 seconds. ) If it is short, initial positioning of the pulse motor 11& is not performed.

Time adjustment is next to this pulse motor driven μm chin 1600! - Proceed to Chin 170G and set f period to g□m5eo
Then, the process returns to the calculation data setting routine 1200.

Then, the arithmetic processing from the calculation data setting .mu.m pin 120o to the time adjustment .mu.m chin 1700 is repeatedly executed at a cycle of 80 m5eo.

In the above embodiment, the calculation switching from the first destination to the second destination is performed by inputting the NAV key 352, but when calculating the first destination, the second It is possible to calculate data (distance components pX, py with respect to the second destination) necessary for calculating O to the destination from the starting point.

9 indicates that two destinations can be set, but 9 indicates that more destinations can be set as necessary.

Furthermore, we have set the second destination as a distance component to the first destination, but we have also set a distance component that overlaps with the starting point, so that if you press the NAV key 352 at any time, you can return to the second destination. The straight line distance and relative direction to be awarded may also be displayed.

As stated above, in the present invention, the destination setting section includes the first. Relative position coordinate information to each of the 20 destinations is set! At the same time, set this Q to 9JI11. The data of the relative position coordinate information of jI2 is stored in the calculation means, and the stored data of the relative position coordinate information of jll and 1l12, the distance signal of the distance detection means) and the direction signal of the direction detection means are used. Based on Section 1C) for the driving point
Calculate the distance and direction information to the destination, calculate the distance and direction information to the second destination at a predetermined timing, and calculate the distance and direction information to the first destination and the second destination. Since either the distance or direction information is displayed on the display flat screen, it is possible to set and operate multiple destinations at the departure point, and this allows the This has the advantage that there is no need to perform the troublesome setting operation of setting the next destination.
