As shown in fig. 2, the method includes:
and S110, acquiring the running state information of the current vehicle and the state information of the target object in front of the current vehicle in a trigger state when the automatic emergency braking system is in the trigger state.
In the embodiment of the present invention, the triggering state refers to an operating state in which the automatic emergency braking system is triggered, for example, the triggering state may be an early warning state or a braking state. It can be understood that when the automatic emergency braking system is in the trigger state, it indicates that the current vehicle may encounter a dangerous situation, and the automatic emergency braking system needs to be used for braking, so as to avoid or reduce the occurrence of collision accidents such as rear-end collision, and the state information value in the trigger state is higher, which is beneficial to the analysis of the follow-up braking reason.
The driving state information of the current vehicle refers to information collected or generated in the driving process of the current vehicle. Optionally, the driving state information of the current vehicle includes at least one of the following data: brake activation information, body electronic stability system status information, steering wheel speed angle, vehicle yaw rate, vehicle lateral acceleration, accelerator pedal position, vehicle travel speed, longitudinal acceleration, and brake pedal signals.

Exemplarily, a user can judge whether brake is activated or not according to brake activation information, whether brake is activated or not determines whether AEB trigger is effective or not at the time, and if brake is not activated, collision can be caused, and driving safety is affected. Whether an Electronic Stability Program (ESP) of the vehicle body has a fault or not can be judged according to the state information of the Electronic Stability system of the vehicle body, if the state of an ESP actuator can not be responded or the ESP actuator has the fault, an AEB control request cannot be sent out in time by an upper layer, and therefore the whole vehicle can not have brake performance. If the rotating speed and the rotating angle of the steering wheel, the yaw rate of the vehicle and the lateral acceleration of the vehicle are too large, the AEB system is inhibited, and a braking instruction cannot be sent. And judging whether the current state of the driver has an acceleration request or not according to the position of the accelerator pedal.

After the data platform receives the running state information of the current vehicle and the state information of the target object in front of the current vehicle, a user can call and check the running state information of the current vehicle and the state information of the target object in front of the current vehicle from the data platform to analyze the braking reason,
on the basis of the above embodiment, the method further comprises; acquiring camera data in a time interval associated with the time information of the trigger state; and uploading the camera shooting data in the associated time interval of the time information of the trigger state to a data platform.

The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical host and VPS service are overcome.
It should be understood that various forms of the flows shown above may be used, with steps reordered, added, or deleted. For example, the steps described in the present invention may be executed in parallel, sequentially, or in different orders, and are not limited herein as long as the desired result of the technical solution of the present invention can be achieved.
The above-described embodiments should not be construed as limiting the scope of the invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made in accordance with design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
