System for monitoring and controlling motor vehicle running condition.

摘要

A system for monitoring and controlling a running condition of a motor vehicle such as a motorcycle has a wheel speed sensor (16,16a) and first (62) and second (64) CPUs. The first (62) and second (64) CPUs effect in a first mode, i.e., when an anti-lock brake control mode is not effected, the same calculations to produce calculated data to monitor the running condition of the motor vehicle, and compare the calculated data from each other to check the effected calculations. In a second mode, i.e., when the anti-lock brake control mode is effected, the first CPU (62) continues the calculations to produce calculated data to monitor the running condition of the motor vehicle, and the second CPU (64) performs an auxiliary controlling function for controlling the running condition of the motor vehicle by controlling a brake mechanism in the anti-lock brake control mode. <IMAGE>
