A car remote control matching method

Abstract

The invention relates to a car remote control matching method. The method comprises the steps that a serial number of each car remote control key is stored into a main engine plant device; when a current car remote control key needs to be matched with a current car, the current car remote control key enters a study mode, a main engine plant receives an RF signal transmitted by the current car remote control key, the main engine plant device obtains the series number of the current car remote control key, and comparison is conducted on the series number of the current car remote control key and the stored series number of the car remote control key so as to determine whether the current car remote control key is a car remote control key which the current car wants to match or not; if the current car remote control key is the car remote control key which the current car wants to match, a current car body controller BCM starts a study state, the main engine plant sends the series number of the current car remote control key to the current car body controller BCM, and study matching is conducted on the current car remote key and the current car.

Description

Technical field [0001] The invention relates to a remote matching method for automobiles. Background technique [0002] The vehicle production line is where the vehicles of the automobile manufacturers are concentrated. In the places where the vehicles are concentrated, there are two main problems in the learning and matching method of the existing car remote key and the vehicle. One is that the body controller BCM opens the learning and matching status window, which is easy to It is known that other remote control keys are learned and matched to the vehicle body controller BCM, which will cause mismatching; second, if there are two or more positions on the vehicle production line performing remote control learning and matching, it is easy to cause cross matching. The fundamental reason for the mismatch is that in the remote learning and matching, the car remote key transmits the information in the remote control into the BCM through the RF signal, and the RF signal of the remote...

Problems solved by technology

[0002] The complete vehicle production line is the place where the vehicles of the automobile manufacturers are concentrated. In the place where the vehicles are concentrated, there are two main problems in the existing learning and matching method of the car remote control key and the vehicle. It is known that other remote keys are learned and matched to the vehicle body controller BCM, resulting in mismatching; second, if two or more positions on the vehicle production line are performing remote learning and matching, it is easy to cause cross-matching. The root cause of the mismatch is that the remote control key of the car transmits the information in the remote control to the BCM through the RF signal during the remote learning and matching, and the RF signal of the remote control key can generally achieve a long transmission distance
