The invention discloses an inter-vehicle information transmission method based on Bluetooth communication. The method comprises the following steps: S1: inputting a trigger signal through a first terminal device; S2: extracting licence plate information of a preceding vehicle through the first terminal device; S3: broadcasting Bluetooth handshake information through a first Bluetooth module in thefirst terminal device, wherein the Bluetooth handshake information comprises the licence plate information of the preceding vehicle extracted in step S2 and a control instruction sent by the first terminal device; and S4: judging, by a second Bluetooth module, whether the received Bluetooth handshake information matches the own license plate information, and if so, transmitting the control instruction to a second terminal device to execute a corresponding control action. The inter-vehicle information transmission method has the following effects: the demand that a subsequent vehicle activelysend a prompt message to a preceding vehicle after traveling at a close distance can be met, in the case that the preceding vehicle cannot be directly prompted by the existing light and whistle, the control instruction can be directionally transmitted through a short-distance Bluetooth connection, thus provide a more convenient driving environment for drivers.

The invention discloses an intelligent navigation method, a terminal and a computer readable storage medium. After a user sets a navigation destination, the terminal completes navigation route planning, and the user confirms that a navigation function is enabled, the terminal detects whether or not it is within a usual movement area of the user (the usual movement area of the user is determined bythe terminal according to historical navigation route information) according to the current real-time position, and if the terminal is within the usual movement area of the user, route navigation prompting is not conducted. In this way, since in the driving process, the current position of the terminal is changed constantly, once it is detected that the terminal is within the usual movement areaof the user, it is shown that a road in the area is familiar to the user, the user does not need route navigation prompting, the terminal does not conduct route navigation prompting, information inputto the user from the outside is reduced, the interference with the user is thus reduced, a better driving environment is created for the user, and the user experience is improved.
