Title:
CONSTANT SPEED TRAVELLING SYSTEM FOR CAR
Document Type and Number:
Japanese Patent JPS5872215
Kind Code:
A
Abstract:
PURPOSE:To reduce driver's uneasiness and to maintain safety travelling by positively displaying autodriving car speed corresponding to autodriving operation. CONSTITUTION:Signals from a main switch 3, input switches 4-6 and a car speed sensor 7 in a car are inputted to a constant travelling controlling device 1 and a slottle actuator driving signal from the device 1 drives a slottle actuator 2. A microcomputer 19 incorporated in a speed meter 8 operates a car speed signal from the sensor 7 and displays the operated car speed on a car speed display part 20. The device 1 is provided with an operation circuit 9 for inputting the output of a crystal oscillator 11 and the output of a reset circuit 12 connected to the switch 3. The signals from the switches 4-6 and the sensor 7 are inputted to the circuit 9 through an input buffer 13, communication data including data corresponding to autodriving operation are sent to the speed meter 8 and the autodriving car speed is displayed on the display part 20.
