Vehicle running condition monitoring method, device, computer device and storage medium

Abstract

The invention relates to a vehicle driving condition monitoring method, a device, a computer device and a storage medium. The method comprises the following steps: acquiring three-axis acceleration and three-axis angular velocity of the vehicle to form original data; preprocessing the original data; establishing the coordinate system of digital horizontal platform according to the original data after preprocessing; converting a digital horizontal platform coordinate system to a vehicle-mounted coordinate system; based on the vehicle coordinate system, outputting the acceleration component without the gravity acceleration component in the traveling direction, the lateral direction, and the vertical road surface direction, and outputting the angular velocity value of the pitching direction,the angular velocity value of the yawing direction and the angular velocity value of the rolling direction based on the digital horizontal platform coordinates; processing the acceleration component without gravity acceleration component in driving direction, lateral direction and vertical road direction to form waveform characteristics. According to the waveform characteristics, pitch direction angular velocity value, yaw direction angular velocity value and roll direction angular velocity value, the vehicle driving state is obtained. The invention reduces the occurrence of traffic accidents.

Description

technical field [0001] The invention relates to a vehicle running state monitoring method, more specifically a vehicle running state monitoring method, device, computer equipment and storage medium. Background technique [0002] At present, the number of domestic motor vehicles and drivers is increasing rapidly, and various accidents occur every day, especially accidents involving large trucks, which are usually major accidents, and the traffic safety situation is severe. Investigate its reason is various, among them the traffic accident that dangerous driving causes accounts for the majority, and most of traffic accidents are all because the driver's negligence causes; Especially the driver's energy is not easy to concentrate after driving for a long time, it is easy to cause the vehicle to The direction is free, even entering the adjacent lane. [0003] At present, there are some devices on the market that are aimed at monitoring the driver's own driving state; such as th...

However, because it completely relies on the image analysis of the face, and its analysis basis is set according to the statistical data of the experiment, for different objects, the analysis results must have certain errors; moreover, this type of detection equipment is only Monitor the status of the driver itself to play an indirect reminder; that is, the driver cannot be reminded by the driving status of the vehicle itself to provide driving guidance
