Wherein the TBOX communication information should contain all information that the vehicle would otherwise need to display on the meter to ensure the integrity of the information displayed on the terminal (cell phone APP).
Secondly, based on the hard-wire communication connection and information interaction of the terminal and the hard-wire interface of the instrument installation position of the vehicle (the vehicle with the instrument configuration cancelled).
The vehicle state information which can be displayed on the meter of the vehicle refers to the vehicle state information which is originally used for being displayed on the meter on the vehicle with the meter configuration cancelled.
The vehicle state information typically includes at least one of:
and the first vehicle state information is output by a vehicle control unit VCU of the vehicle.
And second vehicle state information output by the motor drive controller MCU of the vehicle.
And third vehicle state information output by a battery management system BMS of the vehicle.
Fourth vehicle state information output by an engine management system EMS of the vehicle.
Fifth vehicle state information output by a transmission control unit TCU of the vehicle.
And sixth vehicle state information output by a vehicle body electronic stability system (ESP) of the vehicle.
Seventh vehicle state information output by an electric power steering system EPS of the vehicle.
Eighth vehicle state information output by an electronic parking brake system EPB of the vehicle.
Ninth vehicle state information output by the advanced driving assistance system ADAS of the vehicle.
In a specific application, the vehicle status information should at least include vehicle status information that must be displayed according to the requirements of legal regulations, design specifications, etc., such as real-time vehicle speed, driving mileage, gear position and remaining energy (e.g., remaining oil amount, electric quantity) information, etc., of the vehicle, and corresponding warning information, etc., when the vehicle is in an abnormal condition, such as a fault, an emergency brake, etc. Of course, the vehicle status information may also include some vehicle status information that is not necessarily displayed, such as the engine (motor) speed, driving range, entertainment information, etc. of the vehicle, and may be selected by the driver.

2.3) the design of the mobile phone APP user interface UI completely conforms to the relevant standards of the design of the automobile instrument UI, vehicle state information required by regulations needs to be displayed, for example, the vehicle state information required by the vehicle, such as the real-time speed, the driving mileage, the gear position and the energy consumption, and the vehicle state information required to be displayed, such as vehicle alarm information (such as fault indicator lamps) when the vehicle is abnormal and the like, and display icons and the like are associated with the corresponding state signals of the vehicle. The driver cannot select to display or not to display (i.e., must display) the vehicle state information that must be displayed.
2.4) the APP display interface of the mobile phone can be a standardized display interface, and can also only display the concerned information (only receiving the vehicle state information which is not necessarily displayed) according to personal preferences, such as the rotating speed of the engine of the vehicle, the driving range and the like; the mobile phone APP displays the UI layout and can be set by a driver.
The vehicle state information that must be displayed and the vehicle state information that does not need to be displayed can be extracted, combined, and the like from the first vehicle state information to the ninth vehicle state information (as shown in fig. 2) that are respectively output by the VCU, the MCU, the BMS, the EMS, the TCU, the ESP, the EPS, the EPB, and the ADAS of the vehicle.
2.5) the mobile phone APP can start the screen projection function of the mobile phone, and project the display information to a specified position such as a front windshield, so that a driver can clearly view the vehicle state information in real time.
2.6) through the mobile phone APP, the driver can send part of operation instructions (as shown in fig. 2) to the whole vehicle to realize interactive control with the whole vehicle.
2.7) the mobile phone APP can detect the vehicle speed, and when the vehicle speed is detected to be greater than or equal to 5kph (kilometer per hour), the operation of the driver on the APP is not responded.
In addition, instrument display platformization can be pushed in the related vehicle enterprises, so that interaction signals of the whole vehicle and the instrument of each vehicle type are unified, and the whole display requirement can be adapted through one version of APP software.
3) Vehicle state information is displayed through the mobile phone (taking the mobile phone and the vehicle connected through WiFi wireless communication as an example).
3.1) turning on the mobile phone to search WiFi of the vehicle, and inputting a password (which can be set to be needed when the vehicle is connected for the first time) to connect to the vehicle.
And 3.2) opening the APP of the mobile phone, and inputting an account number and a password for logging in.
3.3) entering an APP interface, selecting a pre-driving vehicle brand, a pre-driving vehicle type and configuration, and automatically configuring a display program and a UI interface by the APP; or the driver can directly select a previously set vehicle configuration; or automatic matching is selected, and the mobile phone APP automatically matches the vehicle according to the configuration word information (the APP has the function of being compatible with the display requirements of multiple vehicle types).
3.4) clicking a mobile phone APP detection connection key, performing communication authentication on the mobile phone APP and a vehicle TBOX, and after the TBOX confirms that the identity information of a vehicle user is legal, sending a start permission instruction (shown in figure 2) to a PEPS (passive entry point) started by one key of the vehicle, and operating the PEPS to start the vehicle by a driver; and recording the VIN information of the vehicle identification number by the mobile phone APP, and calling the recorded user-defined UI.
