Abstract
A loss reduction module of an electric vehicle control device has a function to limit a torque to not exceed a constant loss characteristic and issue a torque instruction if a requested torque exceeds the constant loss characteristic when an ecology switch is turned ON and low fuel consumption travel is instructed. More specifically, when a requested torque exceeding the constant loss characteristic is input, a torque limit is applied to a point on the constant loss characteristic. Accordingly, the torque instruction is output as a torque which is suppressed more than a characteristic curve obtained by combining the constant loss characteristic and a characteristic indicating the relationship between the torque and the number of rotations during normal travel.
