Abstract
In a drive control system for a fuel cell-equipped vehicle including a rotating electrical machine, a control unit includes a rapid warm-up processing module for performing rapid warm-up by the low-efficiency power generation of a fuel cell, a torque command value limiting modulefor limiting the torque command value in accordance with the change of a system voltage caused by rapid warm-up processing, and an FC output command value calculating module for calculating the output command value of the fuel cell in accordance with the limited torque command value. In a storage device connected to the control unit, a system voltage characteristic map which shows the torque-rotation speed characteristics of the rotating electrical machine corresponding to the system voltage is stored.
