The invention discloses an intelligent control device and control method for motor vehicle brake water spraying, belonging to the technical field of cooling electronic control of water spraying by motor vehicle brake drums. The device comprises a set button 2, a selection button 3, an automatic switching switch 4, an LED indicating lamp 5, a water quantity display nixie tube 6, a power supply 7, a braking signal 8, a buzzer 9, a drive circuit 10 and a water spraying electromagnetic valve 11. The control method comprises the following steps of converting the water quantity of a water tank into a corresponding water spraying time, storing the water spraying time in a microprocessor in an hour- minute-second format through the set button and the selection button, analyzing a frequency and an interval of the braking signal by the microprocessor to distinguish a brake state, controlling opening and closing of the water spraying electromagnetic valve, timing the opening time of the water spraying electromagnetic va
