The invention relates to the technical field of urban rail subway control, and discloses a subway vehicle intelligent timing synchronization control panel and a subway vehicle intelligent timing synchronization control method. The alternating current contactor receives an instruction to correct and control alternating current of a plurality of vehicles to be connected in parallel after phase synchronization; the auxiliary control module is used for assisting a control chip to control a semiconductor device to carry out chopping on the direct current; the clock module comprises a crystal oscillator, and the crystal oscillator provides a clock signal for the main control chip; the direct-current power supply module supplies power to the main control module, the auxiliary control module and the clock module; when the direct current power supply module is powered off, a standby battery can continue to supply power to the main control chip and the auxiliary control chip, and it is guaranteed that the clock chip replaces the crystal oscillator to provide clock signals to the main control chip. The power supply phase of the metro vehicle can be accurately corrected so that the two vehicles can be safely connected in parallel, the intelligent degree is high, and the control precision is high.
