摘要： When an electric vehicle outputs a torque instruction, firstly, a request torque is acquired and a judged whether the acquired request torque is positive or negative. Regardless of the sign of the request torque, it is judged whether the eco-switch is ON. If the request torque has a positive sign and the eco-switch is OFF, a map A is selected. If the eco-switch is ON, a map B which limits the maximum torque to a low value for the map A is selected. If the request torque has a negative sign, a map C is selected regardless of the eco-switch ON/OFF state and the maximum torque is not limited.

摘要： 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.

摘要： An electrically operated vehicle driving controller has an electrically operated machine driving section for operating an electrically operated machine; a driving section temperature detecting section for detecting the driving section temperature of the electrically operated machine driving section; a limit ratio calculating processor for calculating a limit ratio for limiting the torque of the electrically operated machine on the basis of the driving section temperature; a rotating speed calculating processor for calculating the rotating speed of the electrically operated machine; and a limit torque calculating processor for calculating an electrically operated machine limit torque corresponding to an electrically operated machine maximum torque set corresponding to the rotating speed on the basis of the limit ratio. Because the torque of the electrically operated machine is limited in a limit ratio corresponding to the temperature of the electrically operated machine, it is possible to prevent the characteristics of the electrically operated machine from being reduced.
