Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a seat belt unfastening reminding method according to an embodiment of the present invention. The seat belt unfastening reminding method can be executed by the seat belt unfastening reminding device provided by the embodiment of the invention, and the device can be realized in the form of software and/or hardware. As shown in fig. 1, the method for reminding the unfastened seat belt specifically includes the following steps:
s110, according to an external change instruction, one of two pre-stored safety belt unfastening reminding logics is determined to be executable safety belt unfastening reminding logics, wherein the two safety belt unfastening reminding logics comprise a first safety belt unfastening reminding logic and a second safety belt unfastening reminding logic, the first safety belt unfastening reminding logic is suitable for a vehicle with a pressure sensor mounted on a rear seat, and the second safety belt unfastening reminding logic is suitable for a vehicle with a pressure sensor mounted on a rear seat.
The external change instruction is a selection instruction input from the outside, and the selection instruction is used for determining which of two pre-stored safety belt unbuckled reminding logics is executable safety belt unbuckled reminding logic.
For example, a designer or an operator before the vehicle leaves a factory selects one of two seatbelt unfastened reminder logics prestored in the logic storage module as the executable seatbelt unfastened reminder logic by inputting the parameter combination code. Specifically, fig. 2 is a schematic flowchart of a logic for determining that an executable seat belt is not fastened according to an embodiment of the present invention. As shown in fig. 2, the external diagnostic device sends an "extended mode entering command" to the diagnostic module according to an external operation, the diagnostic module sends an "unsuccessful reminder" to the external diagnostic device if the "extended mode entering command" is not successfully responded, and sends a "first successful reminder" to the external diagnostic device if the "extended mode entering command" is successfully responded. And after receiving the first success prompt, the external diagnosis equipment sends a safety check command to the diagnosis module, if the diagnosis module determines that the safety check fails, the diagnosis module sends a non-passing check prompt to the external diagnosis equipment, and if the diagnosis module determines that the safety check passes, the diagnosis module sends a passing check prompt to the external diagnosis equipment. After receiving the 'pass check prompt', the external diagnosis device sends a 'command for entering a factory mode' to the diagnosis module, if the diagnosis module does not successfully enter the factory mode, the diagnosis module sends an 'unsuccessful prompt' to the external diagnosis device, and if the diagnosis module successfully enters the factory mode, the external diagnosis device sends a 'second successful prompt' to the external diagnosis device. After the external whole-segment equipment receives the second success reminding, the externally input combined codes of various parameters are sent to the parameter module through the diagnosis module, the parameter module identifies the combined codes, the identified combined codes are compared with the threshold value prestored in the parameter module, if all the parameter values in the combined codes are judged to be within the preset range determined by the corresponding threshold value, for example, the preset range can be a range smaller than the threshold value, the combined codes are determined to be successfully identified, and the diagnosis module sends the 'successful identification reminding' to the external diagnosis equipment. And the parameter module sends the successfully identified combined code to the logic storage module after determining that the combined code is successfully identified, the logic storage module determines one of two types of safety belt unfastening reminding logic which are stored in advance as executable safety belt unfastening reminding logic, and an updating result of the executable safety belt unfastening reminding logic is fed back to external diagnostic equipment through the diagnostic module. Further, the external diagnostic device may send a command for switching the normal mode to the diagnostic module after receiving the update result, and the diagnostic module responds to the command, and if the response is unsuccessful, an external fault may occur, and feeds back the result of the unsuccessful response to the external diagnostic device.
It can be understood that the executable seat belt unfastening reminding logic has uniqueness, the vehicle is set to store two types of seat belt unfastening reminding logics in advance, one of the two types of seat belt unfastening reminding logics is determined to be the executable seat belt unfastening reminding logic through the external change instruction according to the actual configuration situation of the vehicle, and after the configuration of the vehicle is changed, the executable seat belt unfastening reminding logic can be changed through the external change instruction without redesigning the seat belt unfastening reminding logic.
And S120, reminding the user that the safety belt is not fastened according to the executable safety belt non-fastening reminding logic.
When the vehicle is in the situation that the rear seat belt is not fastened, the seat belt unfastening reminding is performed according to the executable seat belt unfastening reminding logic determined in the step 110.
