<p>Provided is a drive control device that is for an electric automobile and that prevents a reduction in driving feeling resulting from torque fluctuations by eliminating a state of non-operation when the front/back distributed torque becomes zero. The present invention is provided with: a battery (13); front/back motor generators (11, 12) connected to driving wheels (21, 23); a driving condition detection device (S) that detects the driving conditions of the vehicle (10); a necessary output torque computation device (552) that computes the necessary output torque (T) in accordance with the driving conditions; a distributed torque value computation device (553) that computes the necessary output torque as a distributed torque using a distribution ratio (alpha); and an output distribution control device (554) that controls the power supply from the battery to front/back electrical rotary machines. In particular, the front/back distributed torques are set to values in the range of the lower limit torques (TFMIN, TRMIN), which are the greatest deceleration torques, and the upper limit torques (TMAXF, TMAXR), which are the greatest acceleration torques, in accordance with the driving conditions of the vehicle.</p> |
