Example Embodiment

[0041] Specific implementation manner one: such as figure 1 As shown, a vehicle steering wheel angle information collection system includes: a three-axis accelerometer 1, a three-axis angular velocity meter 2, a single-chip computer 3, a power supply module 4, a Bluetooth sending module 5, a Bluetooth receiving module 6, a smart phone 7, and a portable computer 8;

[0042] The triaxial accelerometer 1 inputs the triaxial acceleration data to the acceleration input of the single-chip microcomputer 3 through the output terminal of the triaxial accelerometer 1, and the triaxial angular velocity meter 2 inputs the triaxial angular velocity data to the single-chip microcomputer through the output terminal of the triaxial angular velocity meter 2 3's angular velocity input terminal, the single-chip microcomputer 3 will receive the three-axis acceleration data and the three-axis angular velocity data after processing, and then input it to the input terminal of the Bluetooth sending modul...

Example Embodiment

[0050] Specific embodiment two: this embodiment is different from specific embodiment one in that: the information collection device is installed on the side surface of the steering wheel trim, such as figure 2 with image 3 Shown.

[0051] Other steps and parameters are the same as in the first embodiment.

Example Embodiment

[0052] Specific implementation manner three: such as Figure 4 with Image 6 As shown, a method for collecting steering wheel angle information of a car includes the following steps:

[0053] Step 1: The single-chip microcomputer 3 performs data preprocessing on the received three-axis acceleration data and three-axis angular velocity data; the preprocessing includes data reading, calibration and filtering; the three axes are x-axis, y-axis and z-axis Axis, x-axis and y-axis are perpendicular to each other on the plane of the information collection device, the plane formed by the x-axis and y-axis is parallel to the plane formed by the information collection device, and the z-axis is perpendicular to the plane formed by the information collection device (three-axis accelerometer and The three-axis angular velocity meter and the information acquisition device use the same coordinate system);

[0054] Step 2: The single-chip microcomputer 3 takes the three-axis acceleration along the...

Abstract

The invention discloses an automobile steering wheel rotating angle information collecting system and collecting method, and relates to a steering wheel angle information collecting system and method. According to the automobile steering wheel rotating angle information collecting system and collecting method, the problems that installing is difficult, a device is prone to being damaged, operation of a driver is influenced after installing and information collecting precision is low existing in an existing information collecting system are solved. A device of the automobile steering wheel rotating angle information collecting system comprises a triaxial accelerometer, a triaxial angular velocity meter, a single chip microcomputer, a power source module, a Bluetooth sending module, a Bluetooth receiving module, an intelligent mobile phone and a portable computer. The collecting method comprises the following steps that the triaxial accelerometer inputs data to the acceleration input end of the single chip microcomputer through the output end; the triaxial angular velocity meter inputs the data to the angular velocity input end of the single chip microcomputer through the output end; after the single chip microcomputer processes the received data, the single chip microcomputer inputs the data to the Bluetooth sending module through the output end; the Bluetooth sending module transmits the received data to the Bluetooth receiving module; and the Bluetooth receiving module transmits the received data to the intelligent mobile phone or the portable computer. The automobile steering wheel rotating angle information collecting system and collecting method is used for the field of driver driving behavior information collecting.

Description

technical field [0001] The invention relates to the field of driver driving behavior information collection, in particular to an automobile steering wheel angle information collection system and method. Background technique [0002] Steering wheel angle detection plays an important role in studying the driver's operating behavior and driving status in various situations. The characteristic curve of the steering wheel angle can effectively represent the driver's intention to change lanes. At the same time, the time when the steering wheel does not move can indicate the driver's fatigue level and give an early warning to the driver; An important component, its precision and stability are directly related to driving safety. Currently disclosed methods for extracting information on steering wheel angles of automobiles include driving gears fixedly connected to the steering column in the sensor housing, and using gear meshing to detect the angle of rotation of the steering wheel...
