Beschreibung
Zusammenfassung:	In a drive control device for an electric vehicle that includes brake devices (30a to 30d) provided for each of left and right wheels of the vehicle, a front motor (4) and a rear motor (6) for driving and regeneratively braking the wheels of the vehicle, a vehicle motion control unit (37) for calculating a brake application demanded amount corresponding to a yaw moment application amount to be applied to the vehicle based on the traveling state of the vehicle, a brake ECU (31) for controlling the brake devices (30a to 30d) on the left and right sides independently of each other based on the brake application demanded amount to control the yaw moment of the vehicle, and a motor torque control unit (39) for controlling driving torques and regenerative braking torques of a front motor (4) and a rear motor (6), the motor torque control unit (39) executes correction for increasing the driving torque or reducing the regenerative braking torque according to the increase of the braking torques of the brake devices (30a to 30d) based on the brake application demanded amount.
