Example Embodiment

[0017] like figure 1 As shown in the vehicle early warning method, the method is executed on the vehicle terminal installed on the vehicle and the background processing system, and includes the following steps:

[0018] (1) According to the factors related to driving safety, abstract the indicators that need to be paid attention to, and set the corresponding weight value for each indicator;

[0019] (2) Collect vehicle data, including static data, vehicle dynamic data, spatial data, and driver information;

[0020] (3) After receiving the vehicle data collected in step (2), calculate the risk coefficient of each indicator according to the weight value of each indicator and the corresponding vehicle data, and finally add up the risk coefficients of all indicators to obtain the total risk coefficient;

[0021] (4) Judging whether the total risk factor reaches the specified range, if so, execute step (5), otherwise execute step (2);

[0022] (5) Send early warning information t...

Abstract

The invention discloses a pre-warning method for a vehicle. According to the method, the most appropriate pre-warning rule can be customized according to specific feature information of the vehicle, the pre-warning accuracy is high, and risks in the vehicle driving process are greatly reduced. The method is executed by a vehicle terminal and a background processing system mounted on the vehicle and comprises steps as follows: (1), indexes requiring attention are abstracted according to factors related to driving safety, and a corresponding weighted value is set for each index; (2), vehicle data are collected and comprise static data, vehicle driving dynamic data, space data and driver information; (3), a risk coefficient of each index is calculated according to the weighted value of each index and the corresponding vehicle data, the risk coefficients of all the indexes are accumulated, and a total risk coefficient is obtained; (4), whether the total risk coefficient is in a specified range is judged, if yes, the step (5) is executed, and otherwise, the step (2) is executed; (5), a pre-warning message is sent to the vehicle terminal.

Description

technical field [0001] The present invention relates to the technical field of vehicle alarms, and in particular to a vehicle early warning method, which is used to pre-set the warning limit of the vehicle, and trigger the warning system of the vehicle when the warning limit is exceeded. Background technique [0002] With the development and progress of human society, more and more people use cars as a means of transportation. The number of cars on the road increases rapidly, and the traffic accidents also increase rapidly. [0003] At present, there are some vehicle early warning methods on the market, mainly as follows: [0004] 1. Early warning when the vehicle exceeds a fixed speed value. [0005] 2. According to the speed limit value of the road and the current speed of the vehicle, calculate whether an early warning is required. [0006] 3. The terminal installed in the vehicle judges whether the driver is fatigued according to the driving time of the vehicle. [00...
