Abstract

The invention relates to an end-of-line testing tool and a detection method of the testing tool. The end-of-line testing tool comprises a test host, a USBCAN card, a human-computer interaction interface, a scanning device and a printing device. The USBCAN card, the human-computer interaction interface, the scanning device and the printing device are connected with the test host. The end-of-line testing tool sends fault reading, storing and clearing instructions through a CAN bus; a vehicle controller develops corresponding response programs and executes corresponding actions; vehicle key parameters are read according to set content, and are compared with set parameter range to determine whether the vehicle state is normal; action test is carried out on key components and high-voltage relays and the like, feedback result is collected, and result judgment is made; and archives are established for end-of-line vehicles, and traceability of information of the end-of-line vehicles is realized.

Description

technical field [0001] The invention relates to an off-line detector and a detection method using the detector. Background technique [0002] The core components in new energy vehicles include motors, batteries and vehicle controllers, and the communication between the three major components is mainly through the CAN bus. In addition, compared with traditional vehicles, new energy vehicles also add more sensors, high-voltage relays, etc. Therefore, for new energy vehicles, in the manufacturing process, in addition to ensuring the normal assembly and connection of mechanical parts, it is also necessary to confirm the electrical connection , sensors, etc. are no problem, in order to ensure the normal operation of off-line vehicles. [0003] The off-line detector of traditional cars is mainly aimed at engine emission control and other content, and is not suitable for new energy vehicles. During the off-line inspection of new energy vehicles, it is necessary to ensure that the...
