Abstract

The invention discloses a device and method for automatic switching between a plurality of access devices based on a vehicle OBD port. The device includes an input end, an output end and a control circuit board, the input end includes an OBD port connector, the output end includes an OBD port connector and a power port connector or includes two OBD port connectors, two wires extend from the tail of the OBD port connector of the input end and are connected to the OBD port connector and the power port connector of the output end or the two OBD port connectors of the output end, one OBD port connector of the output end is used as a reserved OBD port connector, and the control circuit board is arranged in the OBD port connector of the input end and used for identifying and automatically switching an OBD access device accessed to the output end. The device for automatic switching between a plurality of access devices based on a vehicle OBD port is simple in installation structure, easy to realize and low in cost, and thus facilitates popularization.

Description

technical field [0001] The invention relates to the technical field of automotive electronic accessories, in particular to an automatic switching device and method among multiple access devices based on a vehicle OBD port. Background technique [0002] With the rapid development of automobile technology, the OBD interface is used to communicate the internal information of the vehicle with the outside world, and OBD products are also widely used. At present, there are many OBD products in the automotive electronics industry that need to access the original car OBD data. When the car is returned to the store for maintenance, the 4S shop needs to insert their OBD detection system to detect the vehicle. At this time, the vehicle OBD data is in multiple access. In this case, in order to ensure that the designated party’s data is read completely, other data access must be released. It is necessary to manually unplug the original OBD product, and then connect it to the OBD detectio...
