发明名称 TORQUE DISTRIBUTION DEVICE, TORQUE DISTRIBUTION METHOD, TORQUE DISTRIBUTION VALUE GENERATION METHOD, AND PROGRAM
摘要 <p>This torque distribution device (100) is provided with: a total torque command value acquisition unit (101) that acquires a total torque command value that has been input; an efficiency map acquisition unit (105) that acquires a motor efficiency map (104) of an installed motor; a vehicle speed detection unit (102a) that detects the vehicle speed of the vehicle in which the motor is installed; a drive wheel rotational velocity detection unit (102b) that detects the drive wheel rotational velocity of a drive wheel; a slip ratio calculation unit (103) that calculates the slip ratio of the drive wheel on the basis of the vehicle speed and the drive wheel rotational velocity; a calculation unit (106) that, on the basis of the slip ratio, creates an efficiency change formula that indicates the efficiency value on an operating line indicating the relationship between torque and drive wheel rotational velocity, and calculates the optimally efficient torque value of the efficiency change formula on the operating line; a distribution unit (107) that, on the basis of the total torque command value and the optimally efficient torque value, calculates a torque distribution value with respect to each motor; and a control unit (108) that, on the basis of the calculated torque distribution values, controls the torque distribution to each motor.</p>
