Abstract: Embodiments of the present application disclose a multi-sensor trigger control method, apparatus and device, and a storage medium, and relate to the technical field of sensors. The method includes: acquiring a target output frequency and an output phase set; determining, according to the output phase set and a preset value, an initial value and an overflow value of a counter corresponding to each phase in the output phase set; calculating a reference frequency according to the overflow value and the target output frequency; detecting, according to a received input signal and an output signal corresponding to the reference frequency, whether a phase alignment condition is met; and if the phase alignment condition is met, performing multi-sensor trigger through a trigger control method according to the overflow value and the initial value. By means of the embodiments of the present application, the trigger moment can be flexibly adjusted.
