Embodiment Construction

[0048] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0049] A method for vehicle acceleration warning and emergency braking recording, comprising the following steps:

[0050] Step 1, the vehicle is in the starting stage, collect the X, Y, Z three-axis offset data of the vehicle starting stage, and use the dynamic Kalman filter algorithm to convert the X, Y, Z three-axis offset data into real X, Y, Z Three-axis offset data;

[0051] Step 2, obtain the real X, Y axis offset data, and judge whether the real X, Y axis offset data is within the normal ...

Abstract

The invention discloses a method and system for vehicle acceleration early warning and / or emergency braking recording, which collects the X, Y, Z three-axis offset data of the vehicle, and uses dynamic Kalman filter according to the X, Y, Z three-axis offset data The algorithm converts the real X, Y, Z axis offset data; obtains the real X, Y axis offset data, and judges whether the real X, Y axis offset data is within the normal range of calibration; Abnormal data within the normal value range, emit a signal, and record abnormal data. The invention has the advantages of low cost, small size, high measurement precision, humanized design and the like.

Description

technical field [0001] The invention relates to a method and system for vehicle acceleration early warning and emergency braking recording, a method and system for vehicle acceleration early warning, and a method and system for vehicle emergency braking recording, belonging to the technical field of vehicle operation monitoring. Background technique [0002] Bus passenger injury accidents refer to the sudden acceleration, emergency braking, sudden speed change and other reasons during the operation of the bus, which cause the passengers on the bus to lose their balance and fall, collide, squeeze, resulting in personal injury accident. According to incomplete statistics, in bus passenger injury accidents, when the passengers have not finished sitting still, the accident causes of emergency braking due to the rapid departure of the vehicle and the lack of foresight of the driver to the accident occur, resulting in bus accidents. The occurrence rate of vehicle-passenger injury...
