Embodiment 1

[0056] In the vehicle collision detection method of this embodiment, the acceleration value of the vehicle is measured and recorded every first preset time interval, and as figure 1 As shown, the vehicle collision detection method includes the following steps:

[0057] S 101 , taking the difference between each acceleration value and the acceleration value obtained in the previous measurement as the first difference, taking the difference between each acceleration value and a preset initial acceleration value as the second difference, and taking the first difference value and the second difference is larger as the first acceleration difference;

[0058] S 102 1. For the latest measured acceleration value, judge whether the first acceleration difference falls within a first threshold range, and execute step S when the judgment result is negative 101 , when the judgment result is yes, execute step S 103 ;

[0059] S 103 , Clear all the recorded acceleration values;

[006...

Embodiment 2

[0066] Compared with Embodiment 1, the vehicle collision detection method of this embodiment differs only in that:

[0067] In this step S 103 and the step S 104 Also includes step S between 1031 :

[0068] S 1031 , start counting as a first time-out duration;

[0069] In this step S 104 and the step S 105 Also includes step S between 1041 :

[0070] S 1041 1. Judging whether the first timeout duration is greater than a first timeout duration threshold, and executing step S when the judgment result is yes 101 , execute this step S when the judgment result is negative 105 .

[0071] Wherein the first timeout duration threshold can be set to a definite value by those skilled in the art, the first timeout duration threshold can be set in the range of 3 seconds to 10 seconds, such as set to 5 seconds, to avoid the first timeout duration threshold Too long to cause misjudgment of vehicle impact.

[0072] In this step S 101 and the step S 102 The following steps are a...

Embodiment 3

[0087] The vehicle collision detection device 1 of the present embodiment includes:

[0088] An acceleration measurement module 11, used to measure the acceleration value of the vehicle every first preset time interval;

[0089] A calculation module 12, used to calculate the acceleration difference, the acceleration difference is the larger one of the first difference and the second difference, the first difference is each acceleration value and the acceleration value obtained in the previous measurement The difference, the second difference is the difference between each acceleration value and a preset initial acceleration value;

[0090] A storage module 13, used for storing the acceleration value and the acceleration difference;

[0091] A first judging module 14, used to judge whether the acceleration difference falls within a first threshold range, and enable a second judging module 15 when the judging result is yes;

[0092] The second judging module 15 is used to judg...

Abstract

The invention discloses a vehicle collision detection method and a vehicle collision detection device. In the vehicle collision detection method, acceleration values are measured once at a first preset time interval. The method comprises the following steps: calculating a first acceleration difference value; judging whether the first acceleration difference value falls into a first threshold range to determine whether to continue a flow or not; clearing recorded acceleration values; calculating a second acceleration difference value; judging whether the second acceleration difference value falls into a second threshold range to determine whether to continue the flow or not; under the condition that two judged results are positive, output alarm information. By adopting the vehicle collision detection method and the vehicle collision detection device, collision accident of a vehicle is judged accurately the first time to transmit alarm information rapidly by measuring and analyzing the acceleration data of the vehicle, thereby ensuring that the vehicle can be rescued in time after the collision accident.

Description

technical field [0001] The invention relates to a vehicle collision detection method and a vehicle collision detection device. Background technique [0002] During the running and stopping of the vehicle, the occurrence of a collision event indicates that the vehicle is in an emergency situation, and corresponding emergency treatment is required. In many traffic accidents caused by vehicle collisions, the occupants of the vehicle may be in a coma or seriously injured and life-threatening, and the occupants themselves may not be able to send an alarm message at that time. Striving to get rescue in the shortest time can ensure the safety of personnel's life as much as possible. However, there is a lack of objective data collection and analysis in the prior art, such as calculating and recording the acceleration of the vehicle, so as to automatically determine the driving state of the vehicle and whether an accident has occurred, and further realize the automatic alarm after t...
