SPEED CONTROLLER FOR CAR
Document Type and Number:
Japanese Patent JPS58163023
Kind Code:
A
Abstract:
PURPOSE:To increase the acceleration, by providing an increase setting switch having two contacts to have an increase operation by closing the 1st contact and then to release the overdrive by closing both contacts. CONSTITUTION:A signal (a) is obtained by giving an F/V conversion to a car speed signal and then compared with the output (b) of a memory 102 storing a speed to be set to have compensation 104 of lead angle. Then a control valve coil 108 within a negative pressure type actuator is controlled via an OR circuit 105 and a driver 106 to hold a desired speed. When the 1st contact 110a of an increase setting switch 110 is closed, the coil 108 is electrically conducted via the circuit 105 and the driver 106 to have an increase operation. Then the 2nd contact 110b is closed, and therefore an overdrive cutting coil 109 also conducts via a driver 107 to release the overdrive. As a result, the acceleration is increased more and the speed can be held at a time point when the switch 110 is opened.
