Remote monitoring system and method for electric automobile

Abstract

The invention relates to a remote monitoring system and method for an electric automobile, wherein the remote monitoring system comprises a handheld terminal, a cloud server, a vehicle-mounted communication terminal, a battery management module, an environment collecting module and a whole automobile controller. The system and the method are used; the communication is performed on the basis of a CAN (controller area network) bus technology, so that the cost of the whole system is lower; the power consumption is lower; the performance is more stable; the size is smaller; a CAN transceiver is added; the communication capability of the electric automobile with the handheld terminal and the cloud server is improved; the remote monitoring on the electric automobile is realized; the use state and the environment information of each electric automobile are monitored in real time; each electric automobile can be used for collecting the environment data, the traffic state and the road condition information of each place in a moving way; the latest weather information, the traffic state and the road condition information of each place are obtained through analysis and are issued in a unified way; the application is convenient; the system and the method are suitable for being popularized and applied on a large scale.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to the technical field of electric vehicle management, and specifically refers to a remote monitoring system and method for electric vehicles. Background technique [0002] Currently, the CAN communication network on a car in the prior art mainly includes an automatic transmission control unit, an engine EFI control unit, an ABS system control unit, a vehicle body control unit, and the like. The network load is low, the communication requirements are not high, there is only one layer of diagnostic subnet, the network topology is too single, the scalability is not strong, and in terms of circuit implementation, the existing communication circuits generally do not have any protection measures on the CAN bus. In this case, when the bus load increases, the voltage drop on the bus and in the case of serious signal interference, the bus will appear unstable, and this defect will...

AI Technical Summary

Problems solved by technology

[0004] Because electric vehicles are driven by electricity, there are no emission faults, but there are still faults that affect vehicle safety and functions at this stage, and online diagnosis and records are required to meet the needs of vehicle safety and after-sales maintenance statistics

And for many electronic key components, its service life is a certain period, and it cannot be used beyond the period, otherwise it will bring serious vehicle safety problems
