Problems solved by technology

First, a single portable device judges a collision based on the accelerometer, and the accelerometer may be misaligned, malfunctioning or damaged, resulting in judgment failure or false alarm; second, similar to the shortcomings of OnStar, when a collision occurs, if the communication of the portable device If the module fails or the vehicle is in the blind spot of the communication signal, the center also cannot receive the rescue request

Embodiment approach 1

[0032] figure 1 Shows the system structure of the exemplary embodiment of the present invention, in which the vehicle-mounted device 110 is connected to the portable device 120 and registered at the center-in-vehicle device registration device 130, and then the communication master device selected from 110 and 120 will 110 The in-vehicle data collected with 120 is transmitted to the central vehicle accident judging device 140, and 140 monitors the data and judges whether a vehicle collision event occurs.

[0033] Such as figure 2 As shown, the vehicle safety system is divided into three parts, which are the in-vehicle equipment and center registration part 200, the in-vehicle equipment monitoring data upload part 210, and the central judgment part 230 that the vehicle has an accident.

[0034] image 3 Describes the registration process of in-vehicle equipment and the center. In this process, the center can learn the vehicle in which each portable device is located, so as to facil...

Abstract

According to the invention, a method for detecting vehicle collision events is provided. The method comprises the following steps: a control center device receiving operating state data of a plurality of vehicles, the data being acquired by a plurality of devices in the vehicles and being uploaded; and the control center device using the received operating state data of the plurality of vehicles to determine whether a collision event occurs to the vehicles.

Description

Technical field [0001] The present invention relates to a method for detecting a collision event in a vehicle and a control center device, wherein the control center device uses multiple (ie, greater than or equal to two) devices (including portable devices and vehicle-mounted devices) in the vehicle to collect and upload Incoming vehicle information combines historical information and real-time information of road traffic and communication to determine vehicle collision events. Background technique [0002] The collision of vehicles will cause different degrees of personal injury and property damage. After the crash, whether the emergency rescue center can be notified in time has become an important factor for the survival of the injured, especially for the occupants who were seriously injured in the crash. The traditional crash rescue method is that the occupants of the crashed vehicle or the people near the accident dial the rescue number via mobile phones or other communicat...
