Abstract

The invention provides an optimal tire pressure prompting method for a pure electric vehicle, comprising the following steps: 1) collecting signals: the vehicle controller collects the steering angle signal and the wheel speed of each wheel; 2) data filtering: the vehicle controller collects the The collected steering angle signal judges whether the current driving condition of the vehicle is suitable for manual intervention, and stores the wheel speed in the manual intervention condition, and goes to step 3) Roll radius comparison: the vehicle controller is based on the stored wheel speed Through the setting algorithm, it is determined whether the tire pressure of each wheel is within the preset tire pressure range, and the tire pressure range is determined according to the rolling resistance; 4) Manual intervention prompt: when the tire pressure is within the set tire pressure When the pressure is outside the pressure range, the warning unit will prompt the driver to adjust the tire pressure through manual intervention. The optimal tire pressure prompting method of the present invention avoids the tire pressure change caused by the working conditions and the environment. economic reduction and safety hazards.

Description

technical field

[0001] The invention relates to energy-saving technologies for new energy vehicles, in particular to a method for prompting optimal tire pressure of pure electric vehicles. Background technique

[0002] New energy vehicles represented by pure electric vehicles are undoubtedly one of the important directions for the future development of the automobile industry because of their obvious advantages of environmental protection and energy saving. And with the inclination of relevant national policies, many automakers have launched or focused on research and development of pure electric vehicles. However, currently limited by the bottleneck of battery technology that is difficult to break through, and the construction of basic supporting equipment such as charging facilities has yet to be further improved, so for the development of pure electric vehicles at the current stage, the driving range is one of the key points affecting its promotion. How to optimize the e...
