Title:
SPEED CONTROLLER FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JPS59154514
Kind Code:
A
Abstract:
PURPOSE:To secure the safety of an automatic run by limiting a running speed when signals corresponding to the operation speed of a steering operation device and the running speed are in specific relation. CONSTITUTION:An angle voltage outputted from a position detector varies with the operation speed of the steering operation device. This angle voltage is supplied to the analog input terminal of a digital computer 3 through an input circuit 3. Further, a signal voltage corresponding to the running speed of an automobile is applied to the interruption input terminal of the computer 4 through an input circuit 6. Then, when the operation speed of the steering operation device is within the permissible range of a reference speed, the automobile is held from running at a target speed. A de-energization signal is generated at the output terminal when the level attains to an energization level to open a normally open solenoid valve 12. Then, an electromechanical operating mechanism 11 loses the capability of controlling a speed control element 10. Then, the element 10 is returned to a speed reduction side and the automobile is released from a constant-speed run to perform speed reduction, i.e. limit the speed.
