Abstract

PURPOSE:To avoid an undesired automatic driving process, by starting a setting process when a prescribed period elapsed from the starting time point of setting operation and producing the corresponding signal in a voice. CONSTITUTION:For a car speed control system which performs an automatic driving control, the operation signals supplied from a set/cost switch SW2, a resume/accelerator switch SW3, a cancel switch SW4, etc. are fed to a microcomputer 1 to receive an arithmetic process. Then an alarm indication signal corresponding to the operation, e.g., the deceleration set of ''xxkm/h'' is produced in voices from a voice generating means 24. If a setting operation is carried out yet or again at a time point when a prescribed period elapsed from an operating time point, the ON signal of a release valve 9 is delivered. At the same time, an aural message for setting is delivered through a speaker 15. If no setting operation is carried out at a time point when a prescribed period elapsed, the setting operation is decided as an error. Thus the setting process is inhibited.

A voice message is output, and a vehicle speed display device (l[i
The set vehicle speed will be displayed in l.

In the next set processing routine (106), the determination result in step (202) is rYEsJ, so step (211) is executed this time.

The determination result of this step (211) is rYEs because it is immediately after the start of the ON operation of the set/coast switch (2).

Flip flop number 11! ] path 01), and (2) Step (216)
In order to output one set of voice messages from 71 to 71), a notification instruction signal is output to the 0th floor of the notification device, and (3) step (217) is followed by the step shown in FIG. 4. (The set flag F, which is the subject of determination in step 105'I, is set to "1" and the step shown in FIG. 6 (30
The resume flag F, which is the subject of determination in step 1), is set to "1" to enable subsequent resume operations. Therefore, the flip-flop circuit o1 is maintained in the set state by the above-mentioned release valve ON signal, and V is turned so that the release pulp (9) is reversed and maintained in the closed state 1 decoy, and the voice message "SET" is sent from the speaker 0ω. It will now be output. and the subsequent duty calculation routine (

ES", so the cancellation processing routine" (
108), the route leading to the duty calculation routine (1, 11) via the accelerator processing routine (109) and the coast processing routine (110), 14 choices are made. This route is always selected and the vehicle runs at the set vehicle speed VM until a cancel operation, accelerator operation, or coast operation is performed or a failure occurs in the release valve (9). For example, when a cancel operation is performed or a fault occurs in the valve (9), in the cancel processing routine (108),
Outputs the release valve off signal and releases the release pulp (9
) is reversed to the open state, and the control valve (8) is maintained in the normally closed state by outputting zero value Cv on-period data. In other words, the actuator (
7) is inverted and maintained in the inoperative state, and the throttle valve (

(316) represents the step of setting the set flag F to "1".

In the resume processing routine (107), in a driving state where no regular cent operation has been performed, the resume flag F is "0", so the determination result in step (301) is always rNOj, and the corresponding Immediately after step (301) is executed, the process returns to step (102) shown in FIG.

Furthermore, during the set run after the normal set operation as described above in the 2nd set processing routine, the resume flag Ft has already been set to ``1'' as described above, and the resume flag SwF has been set to ``0''. ”, so
The determination result of step (301) is rYEsJ, the determination result (25) of step (302) is rNOJ, and since the resume/accelerator switch (3) is not turned on, step (303)
Since the determination result is "NO", step (301)

or is executed. For this reason, cancel the rail setting car>
The 1st city message corresponding to ``Resume set
The scolding vM will be displayed first.

When the resume processing routine (107) is executed next time, the determination result of step (3 (12)) is is reversed to rYEsj (26), and the fifth determination step (310) is executed.

At this point, the resume/accelerator switch (3
) has just been turned on, the above judgment step (31
0) is determined as “YESj,” and the judgment step (3
13), step (3]2) is executed.

The value of the resume timer counter N is increased by 1+1. After the counter is pressed, press the resume/accelerator switch (3).
) is incremented regardless of the operation. Then, when the counter N reaches "40" while the switch (3) is turned on, the determination result of the determination step (313) is reversed and a new step (3
14) , Step (315) Oyohi Step (316)
) is then executed, and the subsequent duty calculation routine (1, 11) is executed.

Therefore, an 11-voice message "SET" is output from the speaker US1, and in the duty calculation routine (111), the duty D is calculated based on the Gyance/I/previously set vehicle speed VM. Ru1
, Also, since the above step (316) is executed and the set flag F is set to "1", the determination result of the determination step (105) in the next program execution becomes rYEsJ, and the resume processing routine (10
7) will no longer be executed.

On the other hand, before about 28 hours (until the counter N is counted up to r40J) has elapsed since the start of the ON operation described in 2. When the door and switch (3) are turned off, the determination result of the determination step (310) is 1N.

(403) represents a step of checking the input signal from the valve failure circuit 02 and determining whether or not the release valve (9) is in a failure state.

(404) represents the step of outputting the release pulp-off signal to the flip-flop circuit a0.

(405) represents the step of setting the duty D to "0".

(406) represents the step of resetting the set flag F to "0".

(4,07) represents the step of outputting a corresponding notification instruction signal to the notification device #, (13) so that the voice message "Cancel" is output from the speaker a9.

(40B) converts the branch signal to serial/baworel (2
9) represents the step of outputting to the conversion shift register (41).

In the cancellation processing routine (10B), in the set running state and in the state where the release valve (9) is not broken, the determination results in step (402) and step (403) are both rNOJ, so step A route consisting of step (401), step (402) and step (403) is selected.

Then, when the cancel switch (4) is turned on, the determination result of step (402) is reversed to rYEsJ, and new steps (404) and (405) are performed.
, step (40(i), steps (4,07) and (4,08) force 1 is carried out spontaneously, and the release valve (9) is therefore reversed to the open state. At the same time, the control pulp (8) is inverted and maintained in the closed state, and the actuator (7) is inverted and maintained in the inactive state. In addition, a voice message called ``1 gear'' will be output from the speaker (I).Furthermore, (
30) The set vehicle speed VM displayed on the vehicle speed display section (11) disappears.

If a failure occurs in the release valve (9) while the mataset is running, the failure detection signal is output from the failure detection 11'l path (1), so the determination result at step (403) is
Flip to YESJ and press the cancel switch like above (
When actuator (7) is turned on, actuator (7) is turned on.
) is held in an inactive state, a voice message "Cancel" is output, and the vehicle speed displayed in the history disappears.

above! 111 steps (404), (405),
After (406), (407) and (4,08) are executed.

Set flag F1 is set to “O” in step (406) above.
Therefore, when the next program is executed, the determination result of the determination step (105) shown in FIG. 4 will be rNOJ, and the cancel processing routine (108) will not be executed.

Next, the accelerator processing routine (109) will be explained.

(514) represents the step of outputting the displayed vehicle speed data corresponding to the speed VM of setting 4 after the upper t-S change to the serial/parallel conversion shift register (41).

(515) represents the step of setting the duty D to the maximum value 1) max.

During set driving, the accelerator/response (33) and musinch (3) are not turned on, so the determination result of the determination step (502) is always rNOJ, so step (501), step (502), t, r and step (506) is selected.

Then, while driving the set, the accelerator/resume switch (
3) is turned on. 31: When it turns on, step (
502) is reversed to YESj.

Step (503), step (504), and step (505) are newly executed in sequence. For this reason, Takeda Message, which is a "speed increase set", is the speaker OQ.
Then, before the next execution of the accelerator processing routine (109), the accelerator SwF is already output at step (503) described in -.
is set to "1", the quantification result of step (501) is reversed to rYEsJ, and this time the quantification result of step (50
7) will now be executed. At this point, the resume/accelerator switch (3) has just been turned on, so the determination result in step 2 (507) is r.
YESj and goes through step (510) and step (5
09) is executed, and the value of the accelerator timer force (34) counter O is increased by 1+1. Thereafter, this counter O is incremented regardless of the operation of the resume/accelerator switch (3). When the counter 0 reaches r40J while the resume/accelerator switch (3) is on, the determination result of step (510) is reversed to rYEsJ, and step (511) is newly executed. At this point, the current vehicle speed Vs
is almost equal to the set vehicle speed VM, so this step (51
The determination result of 1) is rNOj, and then step (51
5) is executed and the duty D is set to the maximum value 1) max.

This maximum duty value DmaX is set in steps (10
At step 3), it is output to the interface circuit u(1), the opening of the throttle valve (6) becomes maximum, and the vehicle speed increases.When the current vehicle speed Vs exceeds the set vehicle speed VM by 3 h/h, The determination result of step (511) is rY
The process is reversed to EsJ, and steps (512), (513), and (514) are newly executed.

Therefore, the set vehicle speed VM is rewritten to the current vehicle speed Vs, and the set vehicle speed VM corresponds to the rewritten set vehicle speed VM [X X km/h
A message is output from the speaker a9, and the setting I11.4! The VM displays the display unit (
16).

If the resume/accelerator switch (3) is still turned on, the set vehicle speed V after the speed is rewritten is 11.
Every time M is set to 3/h, steps (512), (513), and (514,) are executed, and the same settings as above are performed.
i changing processing, voice message output processing, and display output processing are performed.

Then, when the desired medium speed is reached after increasing the speed and the on operation of the resume/accelerator switch (3) is released, step (
The judgment result of step (507) is reversed to rN, oj, the accelerator timer counter 0 (direct) becomes "40", and step (5
When the determination result of step 08) is reversed to rYEsJ, step (506) is executed, the accelerator SwF and the accelerator timer counter O are both reset to "0", and the vehicle shifts to constant speed driving as described above.

Next, the coast processing routine (il, o) will be explained.

In FIG. 9 showing the coast processing routine (110), (601) represents the step of determining whether coast SwF is 11''.

(602) Ff: Represents the step of determining whether the set/coast switch (2) is turned on.

(603) represents the step of setting coast SwF to 11''.

(605) represents a step of outputting a corresponding notification instruction signal to the notification device a3 so that the voice message "Deceleration Cent" is output from the speaker 09.

(606) represents the step of resetting both coast SWF, F+5, and coast timer counter P to rOJ.

(607) represents a step of determining whether or not the set/coast switch (2) is turned on.

(608) is based on the value of coast timer counter P (3
7) Represents the step of determining whether the value is, for example, r40JIJ-1=.

(609) represents the step of adding "+1" to the coast timer counter P.

(610) represents the step of determining whether (i(f) of the coast timer counter P is the base value T, for example, r40JIJl.

(611) represents a step of determining whether the current vehicle performance vs is 3 km/h lower than the set vehicle speed VM.

(612) represents the step of changing the set vehicle speed VM to the current medium speed v8.

(613) corresponds to the set vehicle speed VM after rewriting [XX
Shoulder / hj becomes. '+; Represents the step of outputting the corresponding notification number 1 to the notification device θ3 so that the voice message is output from the L speakers.

(615) represents the step of setting the duty D to 10''.

During set running, the coast SwF is 1-0, so the determination result in step (601,) is r N
Oj, and since the set/coast switch 38) (2) is not turned on, the determination result in step (602) is rNOj. For this step (601
), step (602) and step (606) is selected.

After that, when the set/coast switch (2) is turned on, the determination result of the step (602)
gs", and steps (603), (604,), and (605) are newly executed.

Therefore, the voice message "Deceleration set j" is output from the speaker 051.

Then, when the next coast processing routine (110) is executed, since the second self-loading (603) & iron coasting SwF [J has been set, step (6
The determination result of 01) is equal to rYEsJ by one, and step (607) is now executed. At this point, the set/coast switch (2) has just started to be turned on, so the determination result of step (607) is "Y".
Esj, then step (610) is executed, and since the determination result of this step (610) is rNOJ, step (609) is executed and coast timer counter P becomes r+1. J is done.

From now on, this counter P will be used as Sera 1-/Coast switch (2
) is incremented regardless of the operation of -l! l Dot Toast Switch (2) When the value of the above counter P reaches "40" while it is turned on, -1
- The determination result of the edict step (610) is now reversed to rYEsJ, and a new step (611) is executed,
I start to feel happy. The current vehicle speed VS at this point is lower than the set vehicle speed VM (''!
The judgment result IS of 1, 1) becomes rNol, step (61, 5) is immediately executed, and the duty D is set to ``0''.
Set this. As a result, the heavy vehicle decelerates 9. After that, the set/coast switch (2) continues to be turned on, and when the current Ilf speed Vs becomes 3/h below the set vehicle speed VM, step (611 ) is reversed and a new step (61
2) , step (61,3) and step (61,
4) will now be executed. Therefore, the set vehicle speed VM becomes 1. The set vehicle speed VM that has been rewritten to the tonne speed Vs and has been rewritten is displayed on the display fi'? It will be displayed on 01G. Also, the voice message "XXkm/h" corresponding to the rewritten set heavy speed VM is output from the speaker 11.

After that, when the moset/coast switch (2) continues to be turned on and the vehicle speed decreases so that the current vehicle speed 8 becomes 3 km/h below the set vehicle speed VM after the changeover, step (612), step (613) and Step (6
14) is executed, and the set vehicle speed VM is rewritten, the vehicle speed is displayed, and the audio is output in the same manner as above.

Then, when the set/coast switch (2) is turned off, the determination result in step (607) is reversed to 1NO.
The duty calculation routine (111) is executed through step (608) and step (606). Thereafter, the motorcycle will travel at a constant speed at the set motorcycle VM when the switch (2) was turned off.
