OBD mass-produced vehicle evaluation and testing tool and evaluation and testing method

Abstract

The invention discloses an OBD mass-produced vehicle evaluation and testing tool, which comprises a vehicle controller network, a CAN WiFi module, a tablet personal computer and an OBD PVE APP, wherein the vehicle controller is in signal connection with the tablet personal computer by means of the CAN WiFi module, and the OBD PVE APP is installed in the tablet personal computer. The invention further discloses an OBD mass-produced vehicle evaluation and testing method, which comprises the steps of performing hardware connection, running the OBD PVE App, initiating standardized verification, initiating monitoring requirement verification and initiating in-use monitoring performance verification. The OBD mass-produced vehicle evaluation and testing tool and the OBD mass-produced vehicle evaluation and testing method improve the automation degree of OBD PVE testing, reduce the skill requirement for operators , automatically record data and testing results to generate standard report files, and improve the PVE testing efficiency.

Description

technical field [0001] The invention belongs to the technical field of vehicle evaluation and testing, and specifically relates to an OBD mass-produced vehicle evaluation and testing tool, and at the same time, the invention also relates to an OBD mass-produced vehicle evaluation and testing method. Background technique [0002] OBD is the abbreviation of On Board Diagnostics in English, and the Chinese translation is "On-Board Automatic Diagnosis System". (MIL) or check engine warning light (Check Engine) is on, and at the same time, the powertrain control module (PCM) stores the fault information into the memory, and the fault code can be read from the PCM through a certain program. According to the prompt of the fault code, Maintenance personnel can quickly and accurately determine the nature and location of the fault. [0003] After the mass production of the vehicle, the mass production vehicle evaluation test (PVE) must be carried out on the OBD system to verify the c...

Problems solved by technology

[0003] After the mass production of the vehicle, the mass production vehicle evaluation test (PVE) must be carried out on the OBD system to verify the compliance of the OBD system. The OBD diagnostic instrument can realize the diagnostic communication function and transmit the diagnostic results to the outside. However, in the PVE test When applied, it depends heavily on the operator, and the tool itself does not have the ability to cope with the PVE test process, which is not conducive to use
