A data processing method, an obd controller of an on-board automatic diagnosis system, and a vehicle

Abstract

The invention provides a data processing method, an on-board diagnostics (OBD) controller and a vehicle. The data processing method comprises the following steps: acquiring identity information of a connected encryption device; and when receiving data, processing and transmitting the data according to the identity information. According to the scheme provided by the invention, when the data is received, the data is processed and transmitted according to the identity information of the connected encryption device, and the safety can be relatively high; the encryption device is used for encrypting so that the information confidentiality of an OBD interface can be better, and the cracking difficulty and cost are relatively high; furthermore, the data is processed and then transmitted, so that transmission control of OBD information is relatively diversified and specific and the information confidentiality is relatively specific; the encryption device can be graded according to authorities of different people, so that vehicle reading information is filtered and the confidentiality of vehicle information is realized relatively well; and meanwhile, a condition that a user additionally arranges social products without permission can be prevented, and the driving safety and reliability of the vehicle are guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a data processing method, an OBD controller of an on-board automatic diagnosis system and a vehicle. Background technique [0002] In today's society, the OBD (On Board Diagnostics, on-board automatic diagnostic system) interface has become a common configuration on modern cars. Acquisition of fuel consumption, mileage, speed and other information is convenient for car maintenance and understanding of vehicle status. But just because the OBD interface can directly interact with the car's internal network and provide vehicle information externally, it has in turn become a safe intrusion entrance for the car's internal network. Injecting attacks or abnormal data into the car's internal network through the OBD interface can deceive the car's dashboard, ABS warning lights, turn off the engine, and even steal the car without the key, causing serious security problems. [0003] Some...
