The invention belongs to the field of automobiles and relates to an ACC signal acquisition device of vehicle-mounted equipment. The ACC signal acquisition device comprises an ACC signal sending end and an ACC signal receiving end paired with the ACC signal sending end. The ACC signal sending end is connected with an original ACC of a vehicle through a signal line to obtain original ACC signals of the vehicle, process the ACC signals and send out the ACC signals in a RF signal mode. The ACC signal receiving end is connected with the mounted equipment needing the ACC signals, receives the RF signals, converts the RF signals into level signals, and then transmits the level signals to the mounted equipment. The invention further discloses an ACC signal acquisition method of the vehicle-mounted equipment. The ACC signal acquisition method and device of the vehicle-mounted equipment adopt the RF signals to transmit the ACC state signals, through the scheme, signal synchronization is effective and reliable; by the adoption of the RF wireless transmission signals, long wires do not need to be arranged, so the installation is simple, meanwhile, the wire harness cost is lowered, and the problem that the mounted terminal equipment can not obtain the ACC signals is effectively solved.
