  • Electronic control apparatus having a fail-safe mechanism for a vehicle
    Patent number: 5142474
    Abstract: An electronic control apparatus for a vehicle includes first and second controllers between which the transmission of information is performed. A processor in the form of a microcomputer processes information transmitted from the first controller to the second controller and controls an actuator such as a brake actuator based on the information thus processed. An abnormality detecting circuit detects an interruption of signal transmission between the first and second controllers for a predetermined period of time, and it stops the control of the second controller on the actuator when it detects such an interruption. A transmission inhibitor is provided for inhibiting signal transmission from the second controller to the first controller when the abnormality detector detects an interruption.
