Safety system for improving road compatibility of vehicle, vehicle safety system and apparatus, method, and medium

A method for improving road compatibility of a vehicle, wherein the vehicle comprises an external airbag, and the method comprises:

• monitoring an obstacle around the vehicle and acquiring data of the obstacle around the vehicle;
• monitoring vehicle body motion and a vehicle body posture, and acquiring vehicle body posture data and vehicle body motion data;
• computing a collision condition between the vehicle and the obstacle based on the data of the obstacle around the vehicle, the vehicle body motion data, and the vehicle body posture data, the collision condition comprising a collision relative speed and a collision overlap rate;
• and determining, based on the collision relative speed and the collision overlap rate, whether to deploy the external airbag, wherein a determination condition for controlling triggering of deployment of the external airbag comprises:
• if the collision relative speed is less than a first speed threshold and/or the collision overlap rate is less than a first overlap rate threshold, controlling the external airbag to prevent the external airbag from deploying, instead of triggering the external airbag to be deployed;
• and
• monitoring a mental state of a driver in the vehicle, and acquiring mental state data of the driver in the vehicle;
• and computing, based on the state data, the data of the obstacle around the vehicle, the vehicle body motion data, and the vehicle body posture data, a possibility that the driver notices a collision with the obstacle, and computing the collision condition based on the possibility.

A non-transitory machine-readable medium, having a computer program stored thereon, wherein the program is executed by a processor to implement the following steps:

• computing a collision condition between a vehicle and an obstacle based on data of the obstacle around the vehicle, vehicle body motion data, vehicle body posture data, and a possibility that a driver notices a collision with an obstacle based on mental state data of the driver in the vehicle that are input, the collision condition comprising a collision relative speed, and a collision overlap rate;
• and
• determining, based on the collision relative speed, the collision overlap rate, and the possibility that the driver notices the collision with the obstacle, whether to trigger deployment of an external airbag, wherein a determination condition therefor comprises:
• if the collision relative speed is less than a first speed threshold and/or the collision overlap rate is less than a first overlap rate threshold, controlling the external airbag to prevent deployment, instead of triggering the external airbag to be deployed.
