The invention discloses a vehicle wading depth detection and early warning system. An included angle between the orientation direction of an ultrasonic sensor and a vehicle driving plane is a first angle; the water pressure sounding module detects the water depth at the ultrasonic sensor as a first water depth; the gyroscope detects the driving posture of the vehicle; the ultrasonic sensor takes the time interval of receiving the first echo signal and transmitting the ultrasonic wave as a first echo time length, and takes the time interval of receiving the second echo signal and transmitting the ultrasonic wave as a second echo time length; the control module generates an inclination distance and a second water depth; the control module obtains the wading depth of the preset distance in front of the vehicle. The invention further discloses a vehicle wading depth detection and early warning method. According to the vehicle wading depth detection and early warning system and method, early warning of the water depth in front of the vehicle can be completely achieved through the three sensors, the detection result is more accurate, the stability of the system is higher, and the systemis more suitable for the urban ponding environment.
