Abstract

In order to address the issue of motor temperature in hybrid transmission vehicles during uphill acceleration with a heavy load, we conducted a comprehensive analysis on the impact of acceleration on motor temperature rise. Firstly, this study investigates the causes of excessive heat generation in the motor under high torque load, as well as the primary factors contributing to heat production. Secondly, we implemented various calibration strategies to mitigate overheating issues during high torque acceleration. Finally, optimized calibration and real-world vehicle testing were performed for comparison. The test results demonstrate that this calibration method effectively resolves the problem of excessive thermal load during heavy load uphill conditions while also enhancing drivability.
