1. A drive controlling apparatus for an automotive vehicle, comprising:
- at least one couple of road wheels that constitutes one pair of parallel road wheels with respect to a vehicular width direction located on the same axis of the vehicular width direction;
a plurality of motors driving independently and separately each road wheel of the pair of parallel road wheels; and
a power supply to supply an electric power to the plurality of motors, the plurality of motors driving respective road wheels of the pair of parallel road wheels being enabled to constitute a serial circuit with respect to the power supply,wherein the driving controlling apparatus further comprises;
a driving force difference detecting section that detects a difference in a driving force on each of the road wheels which constitutes the pair of parallel road wheels from among the road wheels driven by respective motors; and
a field current correcting section that corrects a field current value of each motor driving the pair of parallel road wheels on the basis of the difference in the driving force.
