Control device of vehicle

Abstract

Abstract PURPOSE:To easily perform repair work of a trouble, by providing a means, in which troubles in an antiskid control circuit and/or car speed sensor are detected to store a trouble location and output a stored contact to the outside on the basis of detection output of the trouble, in a control device of a vehicle. CONSTITUTION:If a motor 20 for a liquid hydraulic pump is disconnected, a transistor T15 in a motor disconnection circuit 20 is turned on to output an H level through a NOR gate 22 and timer 28 and set RS-FF50d of a flip flop group 50, provided as a memory means of trouble location, and a transistor Td is turned on to turn on a display lamp Ld, then disconnection of the motor 20 can be immediately known. Then if abnormality is caused in a power source of an oil hydraulic actuator 13, RS-FF50c of the flip flop group 50 is set by a power source relay trouble detector circuit 26 to turn on a display lamp Lc. On the other hand, if a trouble is caused in a circuit of control logic 12, a control output abnormality detector circuit 30 turns on a display lamp Lb. Further a disconnection detector circuit 33 turns on a display lamp La for disconnection of solenoids 14a-14C.
