The application discloses an information transmission method and an apparatus applied to a vehicle terminal, and is applied to an MCU or an MIPS arranged in the vehicle terminal. The method includes: firstly, to-be-transmitted information is obtained; according to the to-be-transmitted information, a corresponding message is generated, a header of the message includes N bytes, N is smaller than M, and M refers to the byte length of the header in an MODBUS communication protocol; and the message is then transmitted. According to the method, the capacity of the transmitted message is reduced, and bandwidth resources can be saved. In particular, the frequency of information transmission between the MCU and the MIPS is high and can usually reach the millisecond level, and much information can be transmitted so that a lot of bandwidth resources can be saved. 本申请公开种应用于车载终端的信息传输方法及装置，应用于设置在车载终端中的MCU或MIPS。本申请公开的方法中，首先获取待传输的信息，根据待传输的信息生成相应的报文，所述报文的报头为N个字节，N小于M，其中，M为MODBUS通讯协议中，报头的字节长度，然后再传输所述报文。通过本申请公开的方法，进行传输的报文容量减小，
