Abstract:
1. A controller of an electric vehicle having as a power source an electric motor driven based on a torque command value, the controller comprising: a sensor for sensing vehicle information; a torque target value setter for setting a first torque target value based on the vehicle information; a torque command value calculator for calculating the torque command value to the electric motor; a first paragraph calculator for calculating a first paragraph of a second torque target value by implementing a first filtering treatment of the torque command value, the first filtering treatment including a transmission characteristic having a band pass filter characteristic; a second paragraph calculator for calculating a second paragraph of the second torque target value by implementing a second filtering treatment of a motor revolution speed which is one of pieces of the vehicle information, the second filtering treatment including: a torque target value calculator for calculating the second torque target value based on a deviation between: wherein based on the first torque target value and the second torque target value, the torque command value calculator calculates the torque command value, and in the second filtering treatment, the second paragraph calculator uses an attenuation coefficient which is set larger than an identification value of the model of the transmission characteristic.
