1. A safety system for improving road compatibility of a vehicle, wherein the safety system is configured to improve the road compatibility of the vehicle and capable of controlling an external airbag of the vehicle, and comprises:
a monitoring system comprising:
a vehicle external information monitoring module configured to monitor an obstacle around a vehicle body; and
a vehicle body posture monitoring module configured to monitor vehicle body motion and a vehicle body posture; and an integrated safety domain control unit configured to compute a collision condition between the vehicle and the obstacle based on data acquired by the vehicle external information monitoring module and the vehicle body posture monitoring module, the collision condition comprising a collision relative speed and a collision overlap rate, and determine, 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 determining whether the collision relative speed is less than a first speed threshold and/or whether the collision overlap rate is less than a first overlap rate threshold; and
wherein the monitoring system further comprises an in-vehicle monitoring module configured to acquire mental state data of a driver in the vehicle; and the integrated safety domain control unit computes, based on the mental state data and the data that is acquired by the vehicle external information monitoring module and the vehicle body posture monitoring module, a possibility that the driver notices a collision with the obstacle, and computes the collision condition based on the possibility.
