<p>PURPOSE:To improve the safety along with a high reliability by arranging two systems of pattern generators so that they are operated independent of each other when necessary while being operated in double systems normally. CONSTITUTION:When a command Y1 is given at a point X, a pattern generation command Y1 is provided to a terminal B of pattern generators 12 and 14. Then, when a command Y2 is given at a point Y, an inhibition circuit 18 produces no output. This condition is detected with an inverter circuit 24 to operate a monostable multivibrator circuit 26 to generate a zero output for a short space of time. Consequently, the pattern generator 14 clears a pattern P1 at the point Y and then, generates a pattern P2. The patterns generated by the pattern generators 12 and 14 are input into a low level preference circuit 16. This eliminates the risk of overrunning the vehicle thereby providing a operation controller for vehicles with a high reliability and a high safety.</p> |
