When one key is started, the central control exchanges the verification code with the motor controller. If the verification code is out of date, the motor controller runs at full speed; during the driving process, the central control queries the motor controller in real time Data, and related calculations; when one-click is started, the central control uploads the motor controller serial number, and the server verifies whether the serial number is stolen through the product library. 4.2.4 BMS Control The ECU uses different intervals to query BMS data when the vehicle is running or parking. During one-key activation, the central control uploads the BMS serial number, and the server verifies whether the serial number is stolen through the product library. 5 4.2.5 Display of Dashboard data The ECU calculates the speed and mileage through the rotation speed, obtains the time through GPS and RTC, reads the SOC through BMS, and analyzes the status of BMS and motor controller, and controls the instrument to display the time, speed, mileage, SOC, driving status, and fault code. 4.2.6 Display of Charging Time The central control judges whether to enter the charging state by current, time and BMS status, and displays the charging time on the instrument in time. When the power is less than 10%, the central control motor controller limits the 4.2.7 Low battery speed limit speed to the first gear. 4.2.8 Remote Control Vehicle The APP can control the central locking, unlocking, arming, disarming, starting, shutting down, car searching, alarming, etc. through the cloud remote command. 4.2.9 GPS Positing The ECU can be positioned through the GPS module, and obtain and upload the latitude and longitude, time, heading, positioning error, satellite data data. The ECU can control the 4G module to transmit vehicle data to the remote server 4.2.10 Vehicle data transmission through the 4G network. 4.2.11 Transaction alarm The ECU monitors the status of the vehicle in real-time in the parking state, and uploads the data in time when it is detected that the vehicle has fallen or moved. 4.2.12 Robbery data verification The ECU can upload the serial number of BMS, motor controller, central control and SIM card when the electric door is opened. The server side matches the uploaded serial number with the robbery serial number. Send a car lock order. 4.2.13 Battery removal report When the main battery is removed, the ECU uploads the battery removal information. 6 4.2.14 Main battery sleep When the main battery is powered off, the ECU enters a low-power mode, controls the GPS, 4G module, and single-chip microcomputer to sleep to achieve the longest standby time. 4.2.15 A-gps Automatically download ephemeris data to achieve seconds. 4.2.16 485 offline upgrade Through H1 equipment, offline upgrade. 4.2.17 FOTA 4.2.18 Set upload template remotely 4.2.19 Update any data remotely Over-the-air upgrade through differential packages. Achieve faster upgrade speed. The server can arbitrarily define the rules for uploading data in the central control. The server can remotely update any data in the central control data table. 4.2.20 Battery power-on prompt tone A reminder tone is broadcast when the battery is connected to the vehicle. 4.2.21 Battery charging start tone When the battery begins to enter the charging state, it will announce a sound. 4.2.22 Battery charging end sound A reminder tone will be broadcast when the battery is fully charged. 4.2.23 Alarm status changes and uploads to the server actively When the status of the alarm changes, it will actively trigger a synchronous update. 4.2.24 Shutdown without speed overtime When ACC is turned on and there is no vehicle speed for 8 minutes, the central control controller automatically turns off ACC. 4.2.25 Bluetooth function You can start, close, arm and release operations via Bluetooth. 4.2.26 Data storage Server address, secret key, ESN, vibration detection threshold, mileage, low battery speed limit value data storage, alarm associated state, and will not be lost when 7 upgrading the version. 4.2.27 Charging is prohibited 4.2.29 Vibration detection vibration detection threshold can be set. 4.2.30 Dump detection exceeds 60 , report a dump alarm. 4.2.31 Sheepfold (electronic fence) 4.2.28 The riding status does not respond to the remote control When vibration is detected in the central control, a vibration alarm is reported. The Use Gsensor to determine whether the vehicle tilt exceeds 60 , and when it After the electric door is closed, the central control records the latitude and longitude of the parking. When GPS wakes up, compare the distance between real-time positioning and parking latitude and longitude. When the distance exceeds the set value, an electronic fence alarm is reported. 4.2.32 Remote control to modify vibration sensitivity function After long-pressing the start button for 5s, the 1-5 gear switches back and forth and the prompt sound. 4.2.33 Command code matching Send commands via remote or 485, the central control enters the remote control code matching mode, press the remote control to perform code matching. 4.2.34 Battery warehouse inspection (Hall signal) When detecting that the battery is absent, security information will be reported to the network. 4.2.35 Seat cushion detection (Hall signal) When it is detected that the seat cushion is opened, security information will be reported to the network. 8 5 Status and Task Descriptions 5.1 Detailed status and description Vehicle Status Descriptions 4G Module 485 Ready to boot When the remote GPS The ECU sends a command to the lock control(LKU) to make the LKU enter the ready-to-start state. 30s after entering the ready-to-start state, if the central control detects that the faucet lock is open at this time, it will power on, if it does not detect that the faucet lock is open after 30S, the central control will issue a command to the lock control to let the lock control exit the preparation Power on state. control start-stop button is pressed, the central control will send data to the lock control and the whole machine enters the state of ready to start. remote control start-stop button, if you open the faucet lock directly, it will alarm.
