Title:
CONSTANT-SPEED RUNNING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JPS5850012
Kind Code:
A
Abstract:
PURPOSE:To prevent the malfunction with a simple operation, by providing a preset mechanism which can set a prescribed set speed independently of the current running speed and presetting preliminarily a desired set speed. CONSTITUTION:The output of a preset volume 26 is supplied to a capacitor 32 for storage of the vehicle speed through an analog switch 72, and a divided voltage corresponding to the resistance value of the volume 26 is stored in the capacitor 32. For the purpose of storing a preset vehicle speed in the capacitor 32, the signal from a preset switch 18 is supplied to the switch 72. One end of the preset switch 18 is grounded, and the other end is connected to not only the power source side through a resistance 74 but also the switch 72 through an inverter 76. Only when the switch 18 is turned on once and is turned on again within a prescribed time, a turning-on control signal is outputted from an AND gate 78 to the switch 72, and a preset vehicle speed value determined by the volume 26 is stored in the capacitor 32.
