Automatic constant speed driving is widely practiced (Reference: Japanese Patent Application Laid-Open No. 58-1.0783
No. 7, JP-A-58-107835). The automatic constant speed driving system for this purpose consists of an actuator that adjusts the throttle valve opening, a vehicle speed sensor that detects the vehicle speed, and a control circuit that performs feedback control to maintain the vehicle speed at the set speed.
(for example, a microcomputer), but if the microcomputer goes out of control or malfunctions, the automatic constant speed cruise control is executed even though it is not actually set, and the driver's expectations are This could lead to an increase in the speed of vehicles that do not.

By sending out , the control valve control solenoid is controlled on and off to set the pressure in the negative pressure chamber of the diaphragm to a predetermined value. That is, in this case, the control circuit 5 controls the duty ratio of the control signal Sc so that the vehicle speed data SPD of the vehicle speed sensor 6 becomes a preset value.

行制御を実行させるものである。Furthermore, a switching circuit 7 is provided between the control circuit 5 and the actuator 4, in particular with respect to the signal flow for the solenoid for controlling the release valve. As a result, even after the main switch 8 is turned on, the control circuit 5 and actuator 4 remain in contact until the set switch 9 is turned on.
and are separated. Note that the main switch 8 is for receiving power obtained through an ignition switch (not shown), and the set switch 9
sends the cent signal SET to the control circuit 5 to execute automatic constant speed driving control.

的に切離される。The automatic constant speed driving control is canceled by the main switch 8 or the recovery switch 11. For example, when the recovery switch 11 is turned on, the signal RESET is supplied to the control circuit 5, and as a result, the vehicle speed data in the built-in memory is cleared.At the same time, the control circuit 5 turns off the relay coil 72 and closes the contact 73. It turns off. Therefore, the control circuit 5 and the actuator 4 are separated. Furthermore, when the main switch 8 is turned off, the self-holding of the relay coil 103 is released, so the contact 71 of the switching circuit 7 is turned off, and naturally the control circuit 5 and the actuator 4 are electrically disconnected. .
