Problems solved by technology

It can be seen that the current way to realize the networking and intelligence of electric vehicles is to add corresponding modules on the original platform according to the needs. Inconvenient interaction, difficult to coordinate and control all modules of the vehicle
Since the Internet-oriented intelligent electric vehicles in the future have multiple functional modules and multiple interactive networks, the traditional platform architecture does not make reasonable planning between each functional module and network protocol for networked and intelligent applications, and it is difficult to meet the requirements of intelligentization. Demand for Electric Vehicles

Embodiment 1

[0038] Such as figure 1 As shown, the Internet-oriented intelligent electric vehicle platform architecture includes vehicle control ECU18, CAN LAN 28, gateway 49, multimedia system module 33, body accessory system module 31, air conditioning system module 29, power drive control module 26, electric energy storage Control module 24, steering / braking anti-lock brake control module 22, electric steering module 20, vehicle status sensor 19, environment recognition module 17, CAN interface 42, audio interface 38, 4G / 5G interface 40, Bluetooth interface 41, WIFI interface 43. Dedicated short-range communication (DSRC) interface 44, biometric identification interface 46, media-oriented system transport (MOST) interface 37, local area interconnection network (LIN) interface 39, and near field communication (NFC) interface 45.

[0039] Among them, the gateway 49 integrates a CAN interface 42, an audio interface 38, a 4G / 5G interface 40, a Bluetooth interface 41, a WIFI interface 43, a ...

Embodiment 2

[0053] figure 1 Gateway 49 in Figure 4 The structure is designed, such as Figure 4 As shown, the microphone 13, the Bluetooth adapter 6, the wireless router 5, the dedicated short-range communication (DSRC) module 3, the fingerprint recognition module 4, the MOST bus 10, the LIN bus 11, and the NFC adapter 9 are respectively connected to CAN after conversion by the CAN interface module 13. bus7. For data security, the 4G / 5G module passes through the firewall 2 and then connects to the CAN bus 7 through the CAN interface module 13 . The CAN bus 7 is connected to the CAN interface of the vehicle controller EUC8, and is independent of the low-speed CAN interface and the high-speed CAN interface. This solution requires the vehicle controller ECU8 to have 3 independent CAN ports.

[0054] Compared with embodiment 1, the gateway of embodiment 2 directly converts each network protocol to CAN protocol through the CAN interface module, and transmits it through the CAN bus. This s...

Abstract

The invention discloses Internet oriented intelligent electric car platform architecture. A CAN local area network is connected with a multimedia system module, a vehicle body accessory system module, an air conditioner system module, a power drive control module, an electric energy storage control module, a control / antilock brake control module, an electric steering module, a vehicle state sensor and an environment identification module to form the CAN local area network. A whole vehicle control ECU18 is connected with the modules through the CAN local area network. According to the Internet oriented intelligent electric automobile platform architecture provided by the invention, full digital control is applied; nodes are connected through a network and are realized modularly. Personalized customization can be carried out on the modules c according to users. An in-car CAN local area network, the out-car Internet and the Internet of vehicles are connected by module interfaces through a gateway, thereby realizing three-network integration, and an electric car is intelligently controlled through support of cloud data.

Description

technical field [0001] The present invention relates to an electric vehicle platform architecture, in particular to an Internet-oriented intelligent electric vehicle platform architecture, in particular to a networked, modularized, digitized, personalized and intelligent electric vehicle platform architecture. [0002] technical background [0003] The intelligence and networking of electric vehicles is the development direction of electric vehicles in the future, and people pay more and more attention to them. China, the United States, Europe, Japan, etc. have formulated corresponding development plans and carried out many research projects. In order to realize the intelligentization of electric vehicles, it is usually based on the existing vehicle platform architecture to add environmental recognition modules such as vehicle cameras, vehicle radars, and positioning systems, and use the vehicle control ECU to process the collected data and then process the vehicle. control. ...
