Problems solved by technology

However, there may be a problem in the prior art, that is, after a car accident, the GPS antenna may fail to locate
For example, if the GPS antenna falls off or the car is overturned and the GPS antenna is blocked, etc., the location data may not be obtained.
In this case, the vehicle communication module cannot send the MSD carrying effective positioning data to the PSAP, which is not conducive to the timely and effective rescue of the injured

[0049] The present invention provides a kind of MSD data package location acquisition method, comprising:

[0050] Meet the eCall initiation conditions, initiate MSD data packet grouping, and request location, where the request for location is based on the needs of grouping;

[0051] If the location cannot be obtained, request the location calculation to obtain the location and complete the MSD data packet and send an eCall, otherwise directly obtain the location and complete the MSD data packet and send an eCall;

[0052] Wherein, the location calculation includes querying all received external V2X data, analyzing the V2X data to calculate the location or directly using the location in the V2X data of the external terminal, and completing the MSD data packet to send an eCall.

Abstract

The invention discloses an MSD data packet position collection method which comprises the following steps: initiating MSD data packet packing and requesting positioning when an eCall initiating condition is met; if the position cannot be obtained, requesting position calculation to obtain a position completion MSD data packet to send out eCall, otherwise, directly obtaining the position completion MSD data packet to send out eCall; wherein the position calculation comprises the steps of querying all received external V2X data, analyzing the V2X data to calculate to obtain a position or directly adopting the position in the V2X data of an external terminal, and completing the sending of the eCall by the MSD data packet. The invention also discloses an eCALL calling method, a computer storage medium for realizing the steps in the MSD packet position collection method, and an eCALL system. According to the invention, when the vehicle cannot execute positioning, the position information can be obtained from the external terminal to complete MSD data packet packing and send out eCall, safety holes can be simulated and remedied, the probability that injured people are treated in time is obviously improved, and thus the probability of death caused by traffic accidents is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method for acquiring the position of MSD data packets used in an eCALL system. The present invention also relates to an eCALL calling method, a computer storage medium for realizing the steps in the method for obtaining the position of the MSD group package, and an eCALL system. Background technique [0002] Traffic accidents may happen to cars during road transportation. At this time, if rescuers can quickly obtain the necessary information for rescue, casualties and property losses can be greatly reduced. The eCall (vehicle emergency call system) system can automatically dial a rescue call and report the necessary information required for rescue after the accident occurs and the vehicle occupants lose their ability to move. According to EU regulations, all cars sold after April 2018 must be equipped with an eCall system. [0003] The basic principle of eCall is that in the event ...
