An antilock brake control system comprises an output judging device for outputing pumping signal and control signals for controlling the fluid pressure based on a signal from a sensor device for detecting the rotational speed of a wheel, and an inhibiting device for interrupting the control signals when the pumping signal indicates an abnormal condition.

Antilock brake control system

A constant-speed running controller for maintaining the running speed of a vehicle at a fixed level by regulating the degree of opening of the throttle valve of the vehicle. The constant-speed running controller comprises speed detectors for detecting the running speed of the vehicle, a shift position detecting switch for detecting the shift position of the shift lever, a mode selecting switch for switching the running mode of the vehicle between an automatic speed change control mode and an automatic speed change constant-speed running control mode, a throttle opening degree detector for detecting the degree of opening of the throttle valve, a brake switch for detecting the application of the brake system, a target running speed setting switch, a resume switch for restarting the previously established constant-speed running control mode, a constant-speed running mode selecting switch for selecting the constant-speed running control function, a microcomputer for processing data received from the foregoing switches and detectors and giving control signals to the functional devices for regulating the running speed of the vehicle. An effective target running speed for constant-speed running is determined on the basis of a temporary target running speed, an average running speed obtained by processing sample running speeds sampled in a predetermined time interval, and the difference between the temporary target running speed and the average running speed.
