POWER SUPPLY CIRCUIT FOR ACTUATOR OF ON-VEHICLE TRAVELING CONTROL DEVICE

Japanese Patent JP3672524

B2

PROBLEM TO BE SOLVED: To provide a power supply circuit capable of being manufactured at economical cost for providing electricity to a plurality of control lines from a booster circuit of 1 while taking measures for a power supply circuit of actuators except for an actuator of 1, which are liable to be affected by the action of the actuator of 1 among various actuators controlled by the on-vehicle traveling control device.
SOLUTION: In the power supply circuit, power supply line is branched from the booster circuit 10 for boosting a voltage of the on-vehicle power supply VB, and control signals are sent to two control lines 12a and 12b by SW1 and SW2, power is supplied to a plurality of loads L1 by a driving circuit 14a, each load L1 is driven individually by an operation switch 16, and a load L2 is driven by a driving circuit 14b. An auxiliary control line 12b' is connected to the control line 12b to enable SW3 to apply a standby voltage, and a voltage holding circuit 13 (R, C) is provided on the control line 12a to make the circuit capable of eliminating effects of operation of the control line 12b on the control line 12a.
