Problems solved by technology

However, at present, many commercial vehicles, especially trucks, are not equipped with ESC (Electronic Stability Control System), and usually cannot detect the steering wheel angle data. If a steering wheel angle sensor is installed, the cost is usually high and the installation is very difficult. inconvenient

Abstract

The invention provides a method and device for detecting the steering angle of a vehicle steering wheel. A vehicle-mounted intelligent terminal MCU and a 3D acceleration sensor of the vehicle-mountedintelligent terminal MCU are adopted, parameters such as acceleration and speed of a vehicle are collected in real time, thus the rotation angle of wheels is calculated, and the steering angle of thevehicle steering wheel is indirectly detected. On the basis, a low-pass digital filtering algorithm is introduced to filter the collected centripetal acceleration, so that the detection precision is remarkably improved.

Description

technical field [0001] The invention relates to vehicle control technology, in particular to a method and device for detecting the steering wheel angle of a vehicle. Background technique [0002] With the development of the country's economy, the number of vehicles is increasing year by year with a huge number, and the issue of vehicle driving safety is becoming more and more important. Fatigue driving is one of the important reasons for driving safety hazards. Therefore, the detection and early warning of fatigue driving has become one of the functions that need to be expanded or even standard for various commercial vehicles and passenger vehicles. [0003] At present, in some fatigue driving detection schemes, it is necessary to collect the steering wheel angle data of the vehicle, and then analyze the data through mathematical modeling, so as to judge the driving state of the driver. However, at present, many commercial vehicles, especially trucks, are not equipped with ...
