Abstract: In a sensor control apparatus (2), a GND1 terminal for signal-system circuits and a GND2 terminal for a power-system circuit are separately provided in an external circuit terminal section (31). The ground for the drive circuit of the power system and the ground for the drive circuits of the signal system are disposed independently of each other on a circuit board (20). Further, a first electrical path for connecting the circuit board (20) and an engine control unit is provided independently of a second electrical path for connecting the circuit board (20) and a battery. Therefore, even when a heater control circuit (28) is turned ON, the influence of heater current on an Ip1 cell/Vs cell control circuit (26), an Ip2 cell control circuit (27), and a CAN (Controller Area Network) circuit (29) can be suppressed. Further, since the ground for the sensor-system circuit and the ground for the CAN circuit (29) are rendered common, the layout of the ground wring can be simplified.

A traffic comparitor compares the traffic intensity with a preset traffic-regulation start traffic intensity when it is determined that regulation is to be performed. A regulation control means performs traffic regulation control when a comparison result shows that the traffic intensity is equal to or greater than the traffic-regulation start traffic intensity, and performs regulation control on a maintenance and operation process when the traffic intensity is smaller than the traffic-regulation start traffic intensity.
