Electrically operated vehicle drive controller and electrically operated vehicle drive control method

Abstract

The present invention provides an electric vehicle drive control device, comprising a generator target torque calculation and processing mechanism for calculating a generator target torque (TG*), and an inertia correction rotor for calculating an inertia correction torque based on the generator inertia torque (TGI). Torque calculation processing means, drive motor target torque generation processing means for generating drive motor target torque based on the calculated inertia correction torque, output torque fluctuation index based on an output torque fluctuation index representing the fluctuation of the output torque caused by the inertia correction torque A damping torque correction processing mechanism for torque correction. By calculating the inertia correction torque and correcting the output torque, it is possible to reliably compensate the excess or deficiency of the output torque with respect to the vehicle required torque (TO*), thereby suppressing the occurrence of vibrations in the vehicle drive device.

Problems solved by technology

However, if a filter is used to calculate the angular acceleration, although noise-like interference components can be removed, the calculation of the angular acceleration will cause a delay, and sometimes not only the vibration cannot be suppressed, but the vibration will be increased

In addition, if the angular acceleration is estimated by the above-mentioned state estimation method, due to the mechanical difference between the model used in the state estimation and the actual vehicle driving device, there will be an error between the estimated angular acceleration and the actual angular acceleration, resulting in vibration.
