FIG. 3 is a flowchart showing a control procedure in the above-described conventional constant-speed traveling device for a vehicle. In the figure, it is determined whether or not the speed setting for the constant speed traveling has been performed in step S21, and if the speed setting has not been performed, the process is terminated. However, if the speed setting is performed, it is stored in a memory (not shown). Then, in step S22, the throttle actuator (not shown) is controlled based on the set value to realize the constant speed traveling.

In step S23, it is determined from a signal from a vehicle speed sensor (not shown) whether or not the current vehicle speed is below a predetermined speed, for example, 40 km / h. If the result of the determination is NO, step S22
Return to and continue the constant speed control. However, if the result of determination is that the vehicle speed has fallen to 40 km / h or less, the process proceeds to step S24, and the resume function is canceled so as not to operate. Then, in the following step S25, the set speed in the memory is erased, and the process ends.

(Problems to be Solved by the Invention) However, in the above conventional example, when the vehicle speed drops below a predetermined speed, the set speed stored in the memory is deleted. When the vehicle speed is once decreased and then restored to a predetermined speed or more, there is a problem that a situation occurs in which the vehicle cannot be realized despite the intention to resume the constant speed traveling. Therefore, when the driver tries to run at a constant speed again, it is necessary to set the speed again, and there is a disadvantage that the usability of the constant speed running is poor.

In step S3, the CPU 2 determines whether or not the current vehicle speed is a predetermined speed, for example, 40 km / h or less, based on a signal from the vehicle speed input circuit 11. If the result of the determination is NO, the process returns to step S2 and the control of the constant speed traveling is continued. However, as a result of the judgment,
If the vehicle speed has fallen below 40 km / h, proceed to step S4,
When the resume / accel switch 13 is pressed, the resume function is canceled so that the resume function does not operate.

In the next step S5, it is determined whether the vehicle speed is 0 km / h, that is, whether or not the vehicle has stopped, and if the vehicle has not stopped, the resume function is canceled again in step S4. However, if it is determined in step S5 that the vehicle has stopped, the process proceeds to step S6, and thereafter, it is determined whether the vehicle speed has exceeded 40 km / h again. If this determination is NO, the process returns to step S4 to release the resume function. However, if it is determined that the vehicle speed has exceeded 40 km / h again, the process proceeds to the next step S7.

If the resume operation has not been performed in step S8, the process proceeds to step S10, and it is determined whether or not the timer 2b started in step S7 has counted a predetermined time. If it is determined in step S10 that the predetermined time has not elapsed, the process returns to step S8 to determine again whether or not there is a resume operation. When the timer 2b has counted a predetermined time, the determination in step S10 is YES, so the process proceeds to step S11, in which the set speed in the memory 2a set in step S1 is deleted, and this processing ends.
