Method and system for detecting steering wheel rotation angle

Abstract

The invention discloses a method and system for detecting a rotation angle of a steering wheel. The system comprises two units. The first unit is provided with a first single chip microcomputer, a first gravity acceleration sensor, a first bluetooth module, a serial port communication module and a power supply module, wherein the first gravity acceleration sensor, the first bluetooth module, the serial port communication module and the power supply module are connected with the first single chip microcomputer through a data line. The second unit is provided with a second single chip microcomputer, a second gravity acceleration sensor, a third gravity acceleration sensor, a second bluetooth module, and a self-power supply module, wherein the second gravity acceleration sensor, the third gravity acceleration sensor, the second bluetooth module, and the self-power supply module are connected with the second single chip microcomputer through a data line. Besides, the method includes stepsof system initialization, establishment of a mathematical relationship, and data outputting. The system having a simple structure is easy to mount; the test method is clear; and the operation requirement for the driver is low.

Description

technical field [0001] The invention relates to the field of driver's driving behavior information collection, in particular to a method and system for detecting the rotation angle of a steering wheel. Background technique [0002] With the development of the national economy, the number of vehicles is increasing year by year. In order to ensure driving safety and reduce traffic accidents, vehicle information detection and related experiments are becoming more and more important. At present, in many vehicle driving safety warnings, wheel steering and other detection schemes and experiments, it is necessary to collect the steering wheel angle data of the vehicle. After the microcomputer obtains the steering wheel angle data, it integrates other information and judges the driving status through analysis. However, at present, many vehicles are not equipped with steering wheel angle detection sensors, so the steering wheel angle data cannot be detected; even if some mid-to-high-...
