AI Technical Summary

Problems solved by technology

There is a large demand for diagnostic equipment, which requires frequent updates and maintenance. The high equipment cost, including the annual software maintenance fee, also restricts the expansion of diagnostic service capabilities of service outlets.
And a large number of simpler faults also take up limited diagnostic capabilities
At the same time, the process of going to and from the maintenance network and waiting for fault diagnosis and elimination also consumes the user's time and affects the experience of using the vehicle.

Abstract

Vehicle-mounted multimedia equipment with a diagnosis function comprises a data storage and processor and a man-machine interaction device, is in data connection with a vehicle bus, is provided with fault diagnosis software, and allows a user to perform off-line fault diagnosis and repair through the control of the man-machine interaction device. The equipment does not depend on external fault diagnosis equipment and remote data communication, is low in use cost and wide in application range, and improves the vehicle use experience. The invention further provides an automobile fault diagnosis method.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a vehicle-mounted multimedia device with a diagnosis function and a diagnosis method. Background technique [0002] With the current electrification, intelligence, and networking development of passenger cars, the number of electronic system subsystems in automobiles continues to increase, the electrical network architecture becomes increasingly complex, and the demand for data signal transmission continues to increase, which also makes vehicle fault diagnosis and troubleshooting more complex. . In the traditional vehicle maintenance process, about 70% of the time is spent on troubleshooting, and the maintenance process only accounts for 30%. The time spent on troubleshooting in the field of new energy vehicles will be further increased. At the same time, with the development of automobile electrification, the mechanical structure of new energy vehicles is simpler than tha...
