Abstract:
There is obtained an inexpensive vehicle electronic control apparatus that is shared by a plurality of inductive loads and performs rapid cutoff of a driving current with low power consumption. On/off operation of a load current preliminarily charges a surge suppression capacitor, which is connected with each of the upstream points of individual opening/closing devices, that are connected in series with each corresponding one of a plurality of inductive loads, by way of discharging diodes, respectively, up to a predetermined limit voltage V0; when following on/off operation generates an increment voltage ΔV in the charging voltage, a discharging transistor is closed and hence the surge suppression capacitor is discharge by way of a discharging resistor.
