Interface converter and vehicle diagnosis system

A vehicle diagnosis system, comprising a vehicle diagnosis device and an interface converter;

• the interface converter comprising a communication contact, a plurality of pin contacts, and a switch switching apparatus;
• the plurality of pin contacts being plugged into the vehicle-mounted automatic diagnosis system interface;
• the communication contact being configured to connect to a vehicle diagnosis device;
• the switch switching apparatus being configured to link the communication contact to any one pin contact among the plurality of pin contacts, so that signals transmitted by the vehicle diagnosis device by means of the communication contact are transmitted to a target pin contact among the plurality of pin contacts;
• and
• the pin contacts of the interface converter being configured to be plugged into a vehicle-mounted automatic diagnosis system interface of a vehicle, and the communication contact of the interface converter is plugged into a diagnosis interface of the vehicle diagnosis device.

An interface conversion method, applied to an interface converter comprising a communication contact, a plurality of pin contacts, and a switch switching apparatus;

• the plurality of pin contacts being plugged into the vehicle-mounted automatic diagnosis system interface;
• the communication contact being configured to connect to a vehicle diagnosis device;
• the switch switching apparatus being configured to link the communication contact to any one pin contact among the plurality of pin contacts, so that signals transmitted by the vehicle diagnosis device by means of the communication contact are transmitted to a target pin contact among the plurality of pin contacts;
• the interface conversion method comprising the following steps:
• acquiring parameter information of a vehicle to be diagnosed;
• determining a target pin contact according to the parameter information;
• and
• controlling the switch switching apparatus to link the communication contact to the target pin contact among the plurality of pin contacts.
