Abstract

Aiming to address the issue of elevated torque distribution in hybrid transmission vehicles during rapid acceleration and deceleration, a comprehensive analysis is conducted on the impact of different conditions on torque distribution. This paper analyzes the estimation of front axle torque and engine torque in the process of acceleration, as well as the primary factors influencing their distribution. Various calibration strategies are introduced to mitigate drivability issues during high-torque acceleration, followed by optimized calibration and comparative real-world vehicle testing. The test results demonstrate that this calibration method effectively resolves the challenge of excessive drivability performance in acceleration and deceleration, with real-world testing showing vehicle acceleration during the process to be less than 5 m/s², significantly enhancing drivability.
