The invention discloses an automobile message signal sending method and system, the automobile message signal sending method is applied to the automobile message signal sending system, the automobile message signal sending system comprises a power P-CAN, an automobile body B-CAN and a T-BOX, the T-BOX is bridged between two network segments of the power P-CAN and the automobile body B-CAN, and the T-BOX is connected between the two network segments of the power P-CAN and the automobile body B-CAN. The T-BOX communicates with a module on the power P-CAN and a module on the vehicle body B-CAN, and the method comprises the steps that a source network segment obtains a message signal, and the source network segment is the power P-CAN or the vehicle body B-CAN; the T-BOX sends the message signal to a target network segment, wherein the target network segment is the vehicle body B-CAN or the power P-CAN; and a corresponding module on the target network segment receives the message signal and executes a corresponding function. According to the invention, during message signal interaction, the load of the gateway can be reduced, and the signal delay phenomenon can be avoided.
