Embodiment Construction

[0031] In the existing analysis of intense driving behavior, by collecting vehicle speed information and calculating the rate of change of vehicle speed within a period of time, that is, the acceleration value during this period of time, it is judged whether intense driving behavior occurs. However, in the above judging method, a large delay is likely to occur in the process of obtaining the acceleration value, and the authenticity of the obtained driving behavior is poor.

[0032] The inventors of the present invention have found through research that, in the existing analysis method of aggressive driving behavior, it is necessary to calculate the acceleration value based on the vehicle speed within a period of time, resulting in a large delay in the process of obtaining the acceleration value, and based on a single The acceleration value is used to judge the intense driving behavior, which is difficult to reflect the overall driving behavior of the driver, and the authenticit...

Abstract

The invention provides a driving behavior detection method and device based on an acceleration transducer, an event data recorder and an automobile. The driving behavior detection method comprises the following steps: sampling acceleration data of the acceleration transducer in a first dimension direction at a pre-set sampling interval, wherein the first dimension direction is parallel to a front-back driving direction of a vehicle and the acceleration data in the first dimension direction has a value and a direction; averaging the acceleration data in the first dimension direction, which is obtained within a first pre-set duration, so as to obtain an average acceleration, wherein the average acceleration has a value and a direction; if the value of the average acceleration is higher than a pre-set threshold value, judging that violent driving behavior occurs. By adopting the driving behavior detection method provided by the invention, the violent driving behaviors of a driver in a driving process can be rapidly and really judged.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an acceleration sensor-based driving behavior detection method and device, a driving recorder and an automobile. Background technique [0002] With the increase of car ownership, analyzing the driver's driving behavior to determine whether the driving behavior is hidden danger is of great significance to enhance vehicle safety and traffic safety. [0003] The cause of a large number of traffic accidents is that drivers have violent driving behaviors during driving, such as sudden braking and rapid acceleration. [0004] In the existing analysis of intense driving behavior, by collecting vehicle speed information and calculating the rate of change of vehicle speed within a period of time, that is, the acceleration value during this period of time, it is judged whether intense driving behavior occurs. Specifically, when the vehicle speed drops within a period of time and the accel...
