I try not to. This is to prevent vehicle speed control from restarting at the vehicle speed set for the expressway even if the resume switch is touched by mistake when driving at a constant speed on an expressway to driving on a regular road. However, when restarting vehicle speed control after taking a break on the expressway, there is an inconvenience in that the user must perform an operation to memorize the set vehicle speed again.

A signal is output. The control circuit 2 is connected to a battery 6 as a power source via a main switch 41 in the control switch 4 and an ignition switch 7, and receives input signals from the vehicle speed sensor 3, control switch 4, parking brake switch 10, and neutral start. They are received from switch 8 and stop lamp switch 12, respectively. Among these, the vehicle speed sensor 3 generates a pulse signal every time the vehicle travels a predetermined distance, and is, for example, a reed switch placed close to a permanent magnet that rotates in synchronization with the wheels. This reed switch generates an intermittent signal as the permanent magnet rotates. The control switch 4 includes the above-mentioned main switch 41, an indicator light 42, a set switch 43, and a resume switch 44.
When the switch 1 is turned on and power is supplied to the control circuit 2, the set switch 43 lights up to indicate that fact. The resume switch 44 momentarily contacts the movable contact 45 to the fixed contact 44a to input a set signal to the control circuit 2. By making contact, a resume signal is input to the control circuit 2. Further, the parking brake switch 10 is turned on when the parking brake is applied, lights up the parking brake lamp 11, and inputs a cancel signal to the control circuit 2. The neutral start switch 8 is turned on when the automatic transmission is in the neutral or parking position, enables the starter 9, and inputs a cancel signal to the control circuit 2. The stop lamp switch 12 is turned on when the brake pedal is pressed and operated, lights up the stop lamp 13, and inputs a cancel signal to the control circuit 2.

るものである。 When the vehicle is running and you want it to run at a constant speed, turn on the main switch 41 to supply power to the control circuit 2, and turn on the set switch 43 for a moment. , a set signal that rises again is supplied. As shown in the flowchart of FIG. 3, the computer 21 first executes a step when the main switch 41 is turned on.
At S1, the memory and counters in the computer 21 are initialized, and since the vehicle speed is now higher than the predetermined vehicle speed VL and a set signal rising from the ground level is input from the set switch 43, the step is started.
Both S2 and S3 are determined to be positive, and in step S9,
The vehicle speed at that time is stored as the set vehicle speed, and vehicle speed control is started in step S10. As is well known, this vehicle speed control receives a vehicle speed signal from the vehicle speed sensor 3, and if the vehicle speed is lower than a set vehicle speed, the duty ratio of the control signal output to the control valve 51 via the amplifier circuit 28 is increased. If the vehicle speed is higher than the set vehicle speed, the duty ratio of the control signal is lowered so that the actuator 5 increases the throttle valve opening. The vehicle speed is controlled so that the vehicle speed approaches the set vehicle speed.

このとき、設定車速の記憶は、解除されない。 While the vehicle speed is being controlled in this way, if the parking brake is operated, the automatic transmission is shifted to neutral or parking position, or the brake pedal is depressed, the parking brake switch 10, Since a cancel signal is generated from the neutral start switch 8 or the stop lamp switch 12, this signal is input to the computer 21 via the OR circuit 24. Since the cancel signal rises in this way, an affirmative determination is made in step S12 in FIG. 3, and the vehicle speed control is canceled in step S13. At this time, the drive signal supplied to the release valve 52 of the actuator 5 via the amplifier circuit 29 is no longer output, and the actuator 5
Stop throttle valve opening control. In addition,
At this time, the memory of the set vehicle speed is not cleared.

のである。 In this way, after the vehicle speed control is canceled, when the vehicle speed becomes equal to or higher than the predetermined vehicle speed V L and the resume switch 44 is turned on twice in order to restart the vehicle speed control, an affirmative determination is made in step S2. In step S3, since the set switch 43 has not been operated at all, a negative determination is made here, and an affirmative determination is made in step S4. And step S5
Then, a software counter n is incremented, and in step S6 it is determined whether n has reached 2 or not. If n is not 2, the step
Wait until S6 is judged negative and n becomes 2,
When n becomes 2, an affirmative judgment is made in step S6,
After resetting the counter n in step S7,
In step S8, it is determined whether the set vehicle speed is stored. If the set vehicle speed is not memorized,
Although vehicle speed control is not performed, if there is memory, an affirmative determination is made in step S8, and vehicle speed control in step S10 is restarted. If the resume switch 44 is turned on only once, the counter n will not reach 2, so vehicle speed control cannot be restarted, and even if the resume switch 44 is turned on by mistake,
The device will not malfunction. In addition, step
The processes of S4 to S7 and steps S7 to S10 correspond to the determination means and the return means of the present invention, respectively.
