Embodiment Construction
[0030] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] The main solution of the embodiment of the present invention is:
[0032] Obtain the current acceleration of the device detected by the acceleration sensor;
[0033] calculating the component of the current acceleration on the current acceleration axis and the component on the preset axis;
[0034] calculating a deviation angle between the current acceleration axis and the preset acceleration axis according to the component on the current acceleration axis and the component on the preset axis;
[0035] The preset acceleration axis is calibrated according to the deviation angle.
[0036] Because the driving behavior detection system is generally implemented based on an accelerometer when performing driving behavior detection. However, due to the installation of the accelerometer, there are inevitable installa...

The invention discloses an acceleration axial-direction calibration method. The method comprises the following steps that a current acceleration, detected by an acceleration sensor, of equipment is acquired; a component of the current acceleration in a current acceleration axial direction and a component of the current acceleration in a preset axial direction are calculated; according to the component in the current acceleration axial direction and the component in the preset axial direction, a deviation angle between the current acceleration axial direction and the preset acceleration axial direction is calculated; according to the deviation angle, the preset acceleration axial direction is calibrated. The invention further discloses an acceleration axial-direction calibration device anda computer readable storage medium. The technical problem of inaccurate judgement on the driving behaviour is solved.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to an acceleration axis calibration method, device and computer-readable storage medium. Background technique [0002] With the popularization of automobiles, various auxiliary functions carried by automobiles are also becoming more and more perfect. At present, many models are equipped with driving behavior detection systems. The driving behavior detection system is generally implemented based on an accelerometer when performing driving behavior detection. However, due to the installation of the accelerometer, there are inevitable installation errors. Due to the installation error of the accelerometer, the acceleration axis detected by it does not match the actual acceleration axis, which leads to the technical problem of misjudgment of driving behavior in the process of driving behavior detection. Contents of the invention [0003] The main purpose of the present invention is to pr...
