AI Technical Summary

⚠Technical Problem

In the driving process of existing new energy vehicles, torque control strategies based on fixed pedal mapping relationships or preset control parameters are difficult to accurately reflect the changing trend of the driver's torque demand, especially in scenarios such as rapid and deep pressing of the accelerator, frequent light braking, or alternating operation of the accelerator and brake. This results in a lag in power output or energy recovery response, affecting driving smoothness and control consistency.

⚗Method used

By acquiring current and historical driving data within the current torque adjustment cycle, a pre-trained prediction model is used to determine the first and second correction coefficients, characterizing the changing trend of the driver's torque demand, and comprehensively determining the target torque adjustment factor, thereby achieving forward-looking identification and continuous correction of the driver's torque demand.

🎯Benefits of technology

It effectively reduces torque response lag in scenarios with rapid throttle changes or frequent braking, improves the smoothness and consistency of drive and energy recovery control, and enhances the stability of vehicle longitudinal dynamic control and driving experience.

Abstract

This application provides a method, system, and vehicle for determining a torque adjustment factor, relating to the field of torque control technology. The method includes: acquiring current driving data of the vehicle in the current time window and historical driving data of the vehicle in a historical time window within the current torque adjustment cycle; inputting the current driving data and the historical driving data into a pre-trained prediction model to obtain a first correction coefficient for the current torque adjustment cycle; determining a second correction coefficient for the current torque adjustment cycle based on the first correction coefficient; and determining a target torque adjustment factor for the current torque adjustment cycle based on the first correction coefficient and the second correction coefficient. This enables proactive recognition and continuous correction of driving intentions, effectively reducing torque response lag in scenarios with rapid throttle changes or frequent braking.
