The invention provides a vehicle cleaning pump and liquid intelligent distribution unit which comprises a cleaning pump, a sensing control module, a plurality of electromagnetic valves and a confluence distribution module, the confluence distribution module comprises a confluence distribution plate, and the confluence distribution plate comprises a main flow channel and a plurality of branch flow channels communicated with the main flow channel. Each branch flow channel can be communicated with the cleaning mechanism of each cleaning sensing sensor, and the on-off of the branch flow channels is controlled by the electromagnetic valves; the outlet of the cleaning pump is communicated with the main flow channel of the confluence distribution plate; the sensing control module receives a control signal that the sensing sensor needs to clean and then controls the cleaning pump to be opened and closed and controls the electromagnetic valve corresponding to the sensing sensor to be opened and closed. According to the vehicle cleaning pump and intelligent liquid distribution unit, the balance of the liquid pressure and the flow of each branch flow channel can be realized, the defects of liquid pressure and flow loss and step-by-step reduction generated by the existing multi-stage three-way serial pipeline flow channel are avoided, and the cleaning effect on a sensing sensor is ensured.
