AI Technical Summary

Technical Problem

In the pure engine drive mode of hybrid electric vehicles, the motor controller consumes a lot of energy and the battery SOC output power is unstable. In the existing technology, the motor torque distribution is inaccurate, which causes the battery SOC output power to fail to meet expectations.

Method used

By determining whether the first motor's required torque is positive when the hybrid vehicle is operating in hybrid mode or pure engine drive mode, and in response to non-positive torque conditions, calculating the accessory's required torque based on the accessory power, and determining the second motor's required torque based on the accessory's required torque for torque distribution.

Benefits of technology

This ensures that the motor does not output zero torque in the working mode, stabilizes the battery SOC output power, reduces energy conversion, saves energy, and improves driving smoothness.

Abstract

The embodiment of the application provides a torque distribution method, device and electronic equipment of a hybrid electric vehicle, relates to the technical field of new energy vehicles, and the torque distribution method of the hybrid electric vehicle comprises the following steps: in the case that the working mode of the hybrid electric vehicle is a hybrid mode or a pure engine driving mode, it is determined whether the first motor demand torque of the hybrid electric vehicle is a positive torque; in response to the first motor demand torque not being a positive torque, the accessory demand torque of the hybrid electric vehicle is determined according to the accessory power of the hybrid electric vehicle; the second motor demand torque of the hybrid electric vehicle is determined according to the accessory demand torque, and torque distribution is carried out based on the second motor demand torque. The application can dynamically adjust the motor torque when the hybrid electric vehicle works in the hybrid mode or the pure engine driving mode, thereby effectively controlling motor energy consumption and saving energy.
