Motor Control Technologies for Improving the Driving Performance of Electric Vehicles: Presented at EVS 31 EVTeC 2018, Kobe, Japan, October 1 - 3, 2018

摘要

A new generation of the Nissan LEAF electric vehicle (EV) was launched in 2017. Maximum torque and maximum power were significantly enhanced by improving the motor control methods according to the characteristics of the hardware. In addition, e-Pedal control that allows the driver to accelerate and decelerate simply by operating the accelerator pedal was adopted on a Nissan EV for the first time. A control methodology was developed that generates optimum motor torque according to the road gradient, making it possible to stop smoothly regardless of the gradient without depressing the brake pedal. These control technologies have greatly contributed to improving the acceleration performance of the new Nissan LEAF and reducing the driver's operational workload.
