The invention relates to the field of constant-speed cruise, in particular to an automatic constant-speed cruise control method. The method includes that cruise key signals are inputted into an instrument IC (integrated circuit), an engine management system (EMS) of an automobile sends cruising states of the automobile to the meter IC through a CAN bus, the instrument IC outputs cruise request signals and target automobile speed signals to the EMS through the CAN bus according to the received cruise key signals and the cruising states, and the EMS performs switching of the cruising states according to the received cruise request signals and the target automobile speed signals as well as the automobile states signals. The instrument IC is involved in the EMS in control logic for completing the cruising function, so that burden of the EMS is alleviated; the EMS sends the cruise request signals, the target automobile speed signals and the automobile state signals sent by other automobile modules according to the instrument IC, switching of the cruising states is realized, and the cruise control mode is more reasonable and perfect.
