System and method for assisting in testing of OBD (on-board diagnostics) equipment

Abstract

A system for assisting in testing of OBD (on-board diagnostics) equipment comprises a running working condition data unit, auxiliary testing equipment and the OBD equipment, wherein the running working condition data unit is connected with the auxiliary testing equipment through a serial port module; and the auxiliary testing equipment is also connected with the OBD equipment through a CAN bus or K bus. Functions of the OBD equipment can be verified without the aid of a real vehicle, dangerous driving testing behaviors such as overspeeding of the real vehicle in a developing and testing process can be avoided, the developing and testing period is shortened greatly, and the labor cost is saved.

Description

technical field [0001] The invention belongs to the field of Internet of Vehicles and automotive electronics, in particular to a system and method for assisting testing of OBD equipment. Background technique [0002] At present, there are endless OBD devices for the Internet of Vehicles, with different functional designs, but they are all OBD-based Internet of Vehicles devices. In the prior art, there is a corresponding vehicle test equipment for the test of the vehicle itself, but there is no related simple test method for different OBD equipment, and it is necessary to install the OBD equipment on a real vehicle for testing, which is limited by vehicle resources. Short and difficult to handle. In addition, before the OBD product goes on the market, it needs to be tested first to verify whether the product can complete the normal operation. If it is found that the OBD device cannot read the vehicle data normally during the test, the tester needs to record this defect; Dur...

Problems solved by technology

In the prior art, there is a corresponding vehicle test equipment for the test of the vehicle itself, but there is no related simple test method for different OBD equipment, and it is necessary to install the OBD equipment on a real vehicle for testing, which is limited by vehicle resources. Shortage and difficult to handle

In addition, before the OBD product goes on the market, it needs to be tested first to verify whether the product can complete the normal operation. If it is found that the OBD device cannot read the vehicle data normally during the test, the tester needs to record this defect; During the process, the driver uses the real vehicle to overspeed and other dangerous driving behaviors, which greatly prolongs the development and testing cycle and wastes labor costs. Therefore, it is particularly important to design a system and method for auxiliary testing of OBD equipment.
