Abstract
The invention provides a method and device for warning against vehicle water wading. The method comprises: measuring a water depth at a predetermined distance in front of a vehicle, based on respective measuring results of a vehicle bottom laser rangefinder, an ultrasonic rangefinder, a vehicle roof laser rangefinder, and a gyro sensor; determining whether the water depth exceeds a safe depth of the vehicle; issuing a vehicle warning message if the water depth exceeds the safe depth. The invention also provides a corresponding device of the method. Compared with the prior art solution in which it is only possible to detect the water depth and issue any warning message after the vehicle wades into the water, the solution of the present embodiment may detect the water depth at a predetermined distance in front of the vehicle before the vehicle wades into the water and issue warning message if the water depth exceeds the safety depth of the vehicle, which improves the efficiency of the vehicle water wading warning, and thus carries out water wading warning in a real sense.
