摘要： A control system for a vehicle (1) provided with a differential mechanism (3) that applies a torque difference to left and right wheels (5) and two electric motors (2) coupled to the differential mechanism (3), the control system including: two control units (11, 12) being connected to each other via high-speed communication means and each controlling one of the two electric motors (2); a first rotation speed sensor (26R) that detects a first rotation speed of a first electric motor (2R) of the two electric motors (2) and outputs the first rotation speed to the two control units (11, 12); a second rotation speed sensor (26L) that detects a second rotation speed of a second electric motor (2L) of the two electric motors (2) and outputs the second rotation speed to the two control units (11, 12); and a superordinate control unit (10) that calculates demanded torques of the two electric motors (2) based on vehicle information of the vehicle (1). At least a first control unit of the two control unites (11, 12) calculates two assigned torques to achieve the demanded torques calculated in the superordinate control unit (10) based on detection signals of the two rotation speed sensors (26R, 26L).

摘要： 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.
