VEHICLE-MOUNTED CONTROLLER AND METHOD FOR ISSUING ABSOLUTE TIME OF VEHICLE AND VEHICLE
A vehicle-mounted controller includes: a GNSS module, an MPU and an MCU. The GNSS module transmits a pulse signal to the MPU via the rigid line and transmits recommended positioning information to the MPU via the serial port line at the moment when a change occurs in high and low levels of the pulse...

| description | A vehicle-mounted controller includes: a GNSS module, an MPU and an MCU. The GNSS module transmits a pulse signal to the MPU via the rigid line and transmits recommended positioning information to the MPU via the serial port line at the moment when a change occurs in high and low levels of the pulse signal; the MPU determines first absolute time according to first reception time when the pulse signal is received, second reception time when the recommended positioning information is received, and the recommended positioning information, and broadcasts the first absolute time to Ethernet network for absolute time synchronization; the MCU determines second absolute time according to time when the pulse signal is received, time when the first absolute time is received, and the recommended positioning information, and broadcasts the second absolute time to a CAN bus for absolute time synchronization. |
