Electronically controlled vehicle remote diagnosis system and its diagnosis method

Abstract

The invention discloses a remote diagnosis system for electronically controlled vehicles, which includes: a collection module, which is arranged on a vehicle to be monitored, and is used to collect vehicle information; a remote diagnosis module, which is connected with the collection module through a CAN network, and is used for The information collected by the acquisition module is used for diagnosis; the server is used to send diagnosis information to the remote diagnosis module, receive and analyze the diagnosis result fed back by the remote diagnosis module, store the diagnosis result, and according to the diagnosis result Analyze vehicle data. The invention provides a remote diagnosis system for electronically controlled vehicles, which can monitor and collect information on vehicles to be monitored in real time, and make a diagnosis for the running status of the vehicles; the invention also provides a remote diagnosis method for electronically controlled vehicles, which can calculate preset risk assessment indicators and risk assessment index to diagnose the vehicle to be monitored.

Description

technical field [0001] The invention relates to the operation monitoring technology of an electronically controlled vehicle, in particular to a remote diagnosis system and a diagnosis method for an electronically controlled vehicle. Background technique [0002] With the continuous progress of remote communication and bus technology, vehicle fault diagnosis and monitoring technology has been greatly developed, enabling vehicles to realize remote diagnosis and monitoring during vehicle driving. [0003] The development of automotive electronic control technology, while improving the economy, power, safety, environmental protection, comfort and handling of the vehicle, makes the structure of the automotive electronic control system more and more complex, and the requirements for the automotive fault diagnosis system are also increasing. Higher and higher. At the same time, it also leads to an increasing shortage of maintenance technicians and experts who can track and master ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the remote diagnosis of vehicles generally adopts the method of triggering fault diagnosis by the background or the user, and the timing of initiating the fault diagnosis by the background or the user is uncertain, which makes the remote fault diagnosis of the vehicle have a certain degree of randomness, and the existing The vehicle remote diagnosis system generally only diagnoses the faults related to the exhaust system of the vehicle engine, and the scope of fault diagnosis is relatively narrow. Therefore, the existing vehicle remote diagnosis method still has a large driving safety hazard.
