Please refer to FIGS. 1 to 3, which is a vehicle emergency window opening system provided by the present invention, which includes a tilt angle sensing module 1, a water level sensing module 2, and a window control module 3.

The tilt angle sensing module 1 is disposed on the vehicle M, and is used to detect the tilt angle value of the vehicle M. In practice, the tilt angle sensing module 1 can be a three-axis acceleration sensor, which is used to sense the gravity acceleration signals of the vehicle in the three directions of X, Y, and Z, and the tilt angle of the axle can be obtained according to the gravity acceleration signals value. In addition, the tilt angle sensing module 1 may also be a three-axis gyro sensor, which is used to sense the angular velocity signals of the vehicle in the three directions of X, Y, and Z, and obtain the tilt angle value of the axle according to the angular velocity signals. In addition, the tilt angle sensing module 1 may also be composed of a plurality of three-axis acceleration sensors and a plurality of three-axis gyroscope sensors.

The water level sensing module 2 is arranged around the vehicle M. Moreover, the water level sensing module 2 includes two oppositely arranged first water level sensors 21 and two oppositely arranged second water level sensors 22, that is to say, the two first water level sensors 21 are in the vehicle M There is a relative setting on the top, two second water level sensors 22 are on the vehicle M, that is, two first water level sensors 21 are on the vehicle M, and the two second water level sensors 22 is arranged on the vehicle M to face left and right.
