ABSTRACT:
A power distribution control device42calculates a low-μ information magnitude, associated with the friction coefficient of the road surface, based on the slip rate and the vehicle acceleration operation magnitude. If the low-μ information magnitude exceeds an addition evaluation threshold, the power distribution control device42adds the low-μ information magnitude. If the low-μ information magnitude does not exceed the addition evaluation threshold, the power distribution control device42subtracts a constant K from a counter. The power distribution control device42makes evaluates a road to have a low-μ when the counter exceeds a low-μ evaluation threshold.
