Embodiment 1

[0040] Such as figure 1 and figure 2 A safe remote control system for electric vehicles is shown, including: a vehicle-mounted unit and a non-vehicle unit, and the vehicle-mounted unit and the non-vehicle unit are connected through a mobile data network; wherein, the non-vehicle unit includes: a remote platform server and a remote platform server connected to it A number of user terminals, the vehicle-mounted unit includes: a data terminal and a centralized controller connected to it, the data terminal is connected to the remote service platform, and the centralized controller is also connected to a number of action execution units;

[0041] The centralized controller includes: a vehicle control unit and several motion control units connected to it, and the motion control unit is connected to its corresponding motion execution unit, and the vehicle control unit is also connected to the data terminal.

[0042] In this embodiment, the remote platform server is a TSP remote pla...

Embodiment 2

[0045] This embodiment is based on the above-mentioned control method for a safe remote control system of an electric vehicle, and the steps are as follows:

[0046] Step 1: The user sends a command to the remote platform server through the user terminal;

[0047] Step 2: After receiving the command, the remote platform server encrypts and packages it, and transmits the packaged message to the data terminal;

[0048] Step 3: The data terminal parses and decrypts the message, then repackages the decrypted message, and sends it to the vehicle control unit, and then the vehicle control unit analyzes the secondary packaged message;

[0049] Step 4: After the vehicle control unit obtains the analyzed control request command, it judges the validity of the control command. If it is legal, it saves the control command and enters step 5. If it is illegal, it does not save the control command and enters step 6;

[0050] Step five: the action execution unit executes the control command;...

Embodiment 3

[0067] This embodiment combines Embodiment 1 and Embodiment 2, and takes the charging function of an electric vehicle as an example to illustrate the control method of the present invention.

[0068] During normal charging, the user terminal firstly submits a remote charging control request command. After receiving the request command, the TSP remote platform server encrypts the command and packages it according to the OTA protocol, and the remote platform server sends the packaged message to T- BOX data terminal; the data terminal parses the message according to the OTA protocol and encryption algorithm. After the message is parsed, it needs to be packaged again according to the CAN bus protocol and application protocol, and then forward the packaged control command message to the vehicle control unit. After the vehicle control unit receives the message, it will analyze it.

[0069] If the vehicle control unit detects the received control command, it will judge the legality o...

Abstract

The invention discloses a safety remote control system used for an electric vehicle, and a control method of the safety remote control system. The safety remote control system comprises a vehicle-mounted unit and a non-vehicle-mounted unit, wherein the vehicle-mounted unit and the non-vehicle-mounted unit are connected through a mobile data network; the non-vehicle-mounted unit comprises a remote platform server and a plurality of user terminals connected with the remote platform server; the vehicle-mounted unit comprises a data terminal and a centralized controller connected with the data terminal, and the centralized controller is further connected with a plurality of action execution units; the centralized controller comprises a complete vehicle control unit and a plurality of action control units connected with the complete vehicle control unit; each action control unit is connected with the corresponding action execution unit; and complete vehicle control unit is further connected with the data terminal. The safety remote control system simplifies and integrates vehicle-mounted control units into the independent centralized controller, thereby reducing the complexity of the structure and links of the safety remote control system, reducing failure links, and being simple and reliable.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a safe remote control system and method for electric vehicles. Background technique [0002] With the deepening of the energy crisis, the vigorous development and continuous integration of electric vehicles and the Internet industry, energy-saving and environmentally friendly electric vehicles have attracted more and more attention and become one of the hot spots in the development of the automobile industry. [0003] In recent years, electric vehicles with remote control functions have been widely promoted and well received. For example, in the scorching summer, most car owners tend to start the air conditioner first to pre-cool the interior of the car before driving. Therefore, electric vehicles with remote air conditioning control functions are highly respected by manufacturers and favored by car owners. Of course, the remote control function is far more than that. There are ...
