Abstract
A vehicle drive control device includes an initially determined request acceleration calculation means for calculating an initially determined request acceleration, an automatic drive control means for receiving the initially determined request acceleration and applying a predetermined torque to each wheel, a torque calculation means for calculating an allowable torque not causing a slip at each wheel when the allowable torque is applied thereto, on the basis of a vertical load applied to thereto and a friction coefficient of a road surface, a limit acceleration calculation means for calculating a limit acceleration acting on the vehicle in a case where the calculated allowable torque is applied to each wheel, and a request acceleration determination means for obtaining a request acceleration on the basis of the limit acceleration and the initially determined request acceleration, and for outputting the request acceleration, replacing the initially determined request acceleration, to the automatic drive control means.
