Abstract

PURPOSE:To prevent malfunction by actuating a regime function when a regime switch is depressed by the prescribed number of times. CONSTITUTION:A main switch 41 is turned on to supply a power source to a control circuit 2 and a computer 21 sets a car speed and controls an actuator 5 to control the car speed. If a break pedal is pressed during the control of car speed, a cancel signal is generated from a stop lamp switch 12. The cancel signal is inputted to the computer 21 through an OR circuit 24 to release the car speed control. In this case, the storage of the set car speed is not released. When the car speed becomes a value less than the prescribed speed, the car speed control is released in the same manner as said case. When the regime switch 44 is turned on twice after releasing the car speed control, whether the set car speed is stored or not is discriminated, and when the storage exists, the car speed control is restarted.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a constant speed traveling device that controls vehicle speed by controlling the opening and closing of a throttle valve of an engine so as to maintain a set vehicle speed.

Conventional constant-speed driving systems have a system that automatically adjusts the vehicle speed to prevent the control circuit from erroneously determining that the vehicle speed is zero and performing control to increase the vehicle speed when the vehicle speed sensor fails and no longer generates a vehicle speed signal. When the vehicle speed drops below a predetermined speed, the vehicle speed control is canceled.

In addition, conventional constant speed driving devices have a resume function, so that even if vehicle speed control is once canceled, vehicle speed control can be resumed without having to perform a vehicle speed setting operation again.When the resume switch is operated, Vehicle speed control can be restarted at the vehicle speed set when vehicle speed control was canceled.

However, if vehicle speed control is canceled due to the vehicle speed decreasing below a predetermined vehicle speed, at the same time as vehicle speed control is canceled,
The memory of the set vehicle speed is also cleared, so that the resume function will not work even if the resume switch is operated. This is to prevent vehicle speed control from restarting at the vehicle speed set for the expressway even if you accidentally touch the resume switch when you transition from 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.

In view of this problem, an object of the present invention is to make it possible to clearly distinguish an operation for activating the resume function from an erroneous operation, so that the vehicle speed control is canceled when the vehicle speed decreases below a predetermined vehicle speed. The purpose is to enable the resume function to work even if the

The canceling means cancels the vehicle speed control while the set vehicle speed is stored when the vehicle speed decreases to a predetermined vehicle speed or less. Further, the determining means determines whether the resume switch has been operated a predetermined number of times. The restoring means is characterized in that when the determining means determines that the resume switch has been operated a predetermined number of times while the vehicle speed control is released by the canceling means, the restoring means restores the vehicle speed control for maintaining the set vehicle speed.

According to the present invention, when the vehicle speed becomes lower than the predetermined vehicle speed,
Even if vehicle speed control is canceled, the resume function can be activated, so for example, when restarting vehicle speed control after a break on the highway, there is no need to perform an operation to memorize the set vehicle speed again. Since the resume function is activated when the switch is operated a predetermined number of times, there is no possibility that the resume function will be activated due to an erroneous operation.

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 center switch 43 for a moment. A cent signal is provided that goes down and then goes up again. As shown in the flowchart of FIG. 3, the computer 21 first initializes the memory and counters in the computer 21 in step S1 when the main switch 41 is turned on, and now calculates the vehicle speed. Since the vehicle speed is equal to or higher than the predetermined vehicle speed vL and a set signal rising from the ground level is input from the set switch 43, an affirmative determination is made in both steps S2 and S3, and in step S9, the vehicle speed at that time is stored as the set vehicle speed, and step Vehicle speed control is started by SIO. As is well known, this vehicle speed control receives a vehicle speed signal from a vehicle speed sensor 3, and if the vehicle speed is lower than a set vehicle speed, an amplifier circuit 2
The duty ratio of the control signal output to the control valve 51 via the control valve 8 is increased, and the actuator 5 acts to increase the opening degree of the throttle valve.If the vehicle speed is higher than the set vehicle speed, the duty ratio of the control signal is increased. is lowered, and the actuator 5 acts to reduce the opening degree of the throttle valve, thereby controlling the vehicle speed so that it approaches the set vehicle speed.

When the vehicle speed is being controlled in this way, if the parking brake is operated, the automatic transmission is shifted to the neutral or parking position, or the brake pedal is depressed, the parking brake switch 10, Neutral start switch 8, or
Since a cancel signal is generated from the stop lamp switch 12, this signal is sent to the computer 2 via the OR circuit 24.
1 is input. Since the cancel signal rises in this way, step 312 in FIG. 3 is answered in the affirmative.
In step S13, vehicle speed control is canceled. 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 stops controlling the throttle valve opening. Note that at this time, the memory of the set vehicle speed is not cleared.

Further, when the vehicle speed control is being performed, if the vehicle speed becomes less than the predetermined vehicle speed VL (for example, 30 km/H), a negative determination is made in step 311, so the vehicle speed control is canceled as in the case described above. Note that this step Sl'l, S1
The process No. 3 corresponds to the canceling means of the present invention.

In this way, after the vehicle speed control is canceled, when the vehicle speed becomes equal to or higher than the predetermined vehicle speed VL, and in order to restart the vehicle speed control,
When the resume switch 44 is turned on twice, an affirmative determination is made in step S2, a negative determination is made in step S3 since the set switch 43 is not operated at all, and an affirmative determination is made in step S4. Then, in step S5, a software counter n is incremented, and in step S6, it is determined whether n has become 2 or not. If n is not 2, a negative determination is made in step S6, and the process waits for n to become 2, and when n becomes 2,
After an affirmative determination is made in step S6, the counter n is reset in step S7, and then it is determined in step S8 whether or not the set vehicle speed is stored. If the set vehicle speed is not stored, no vehicle speed control is performed, but if the set vehicle speed is stored, an affirmative determination is made in step S8 and the vehicle speed control in step 310 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 malfunction. Never. Note that steps 84 to S7 and step 8
Processes 7 to 310 correspond to the determination means and the return means of the present invention, respectively.
