Fig. 1 is a schematic flow chart of an embodiment of the present invention.
Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical scheme of the present invention, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the following examples.
According to the application, by adding the first memory and a global variable and combining the current vehicle speed and a preconfigured effective tire pressure range, the problem of frequent tire pressure false alarm in some existing vehicle types is solved through the unique logic designed above, and the abnormal display of the APP tire pressure of the mobile phone connected with the cloud platform before the vehicle is powered on and started is avoided, so that the false understanding of the vehicle owner before the vehicle is started is avoided.
A tire pressure memory reporting information processing method, as shown in figure 1, comprises the following steps:
when the TBOX is initialized, the global variable needs to be initialized, and at this time, the global variable is initialized to a special value, and the value can represent FF or other meanings, specifically represents that the vehicle is just loaded currently, so that false alarms caused by abnormality of the first memory, the detected tire pressure value and the like are avoided, and meanwhile, related information is provided for an engineer to learn corresponding conditions.
Then, during operation, the detected tire pressure value transmitted by the tire pressure sensor via the CAN bus needs to be read, which is the tire pressure value in the prior art, but in the present embodiment, it is only used as a process value.
Based on the detected tire pressure value, whether the detected tire pressure value is within a preconfigured effective range is required, in this embodiment, the effective range takes 0-3.5bar, if so, the detected tire pressure value is updated and updated as the global variable, and the detected tire pressure value is reported as the effective tire pressure value, the reported information is specifically reported to a TSP platform, the TSP platform is used for providing intelligent service for a user, and the effective tire pressure value can be issued to a mobile phone APP or other more kinds of equipment of the user through the TSP platform, including but not limited to various equipment such as a smart television, a smart watch/a bracelet, and the like, so that the user can know the tire pressure condition of the vehicle; after reporting is completed, the system waits for the next detection period to collect the detected tire pressure value.
In addition, when the TBOX needs to enter a sleep state, this information is characterized by a sleep command, and when the program receives the sleep command, the system stores the current global variable in the first memory, and since this first memory uses a nonvolatile storage medium such as flash, it can provide a valid tire pressure value at the next start, and since the shutdown of the system generally means that the vehicle is stationary, the probability of the vehicle in a stationary state being punctured or insufficient tire pressure is very low, and even if it is maliciously deflated, the user can learn in a very obvious visual or other sensing manner.
In addition, when the detected tire pressure value is not in the interval of 0-3.5bar, the current vehicle speed is required to be read, specifically, the vehicle speed CAN be obtained through a vehicle-mounted CAN bus, and whether the current vehicle speed exceeds a preset first set speed per hour is judged, the first set speed per hour CAN be determined according to the situation, in the embodiment, the current vehicle speed is defined as 30 km/h, if the current vehicle speed exceeds 30 km/h, the global variable is updated to be the detected tire pressure value, the detected tire pressure value is reported as an effective tire pressure value, and likewise, the reported information is specifically reported to a TSP platform, and the TSP platform is used for providing vehicle intelligent service for a user, wherein the effective tire pressure value CAN be issued to a mobile APP of the user or other more various devices including but not limited to various devices such as a smart television, a smart watch/bracelet and the like through the TSP platform so that the user CAN know the tire pressure condition of the user; after reporting is completed, the system waits for the next detection period to collect the detected tire pressure value.
On the contrary, if the current speed of the vehicle does not exceed 30 km/h, the current global variable needs to be read, and whether the current global variable is in a preconfigured effective range is judged, if yes, the current global variable is reported as an effective tire pressure value, and likewise, the reported information is specifically reported to a TSP platform, the TSP platform is used for providing intelligent service for the user, and the effective tire pressure value can be issued to a mobile phone APP or other more kinds of equipment of the user through the TSP platform, including but not limited to various equipment such as an intelligent television, an intelligent watch/a bracelet, and the like, so that the user can know the tire pressure condition of the user; after reporting is completed, the system waits for the next detection period to collect the detected tire pressure value.
In contrast, when, for example, the vehicle is started, the system comes out of the sleep state, at which time the global variable has been emptied, i.e. if the current global variable is likewise not in the range of 0-3.5bar, the global variable stored in the first memory is read and reported as the effective tire pressure value. Because the first memory adopts the nonvolatile storage medium, the data on the first memory cannot disappear in the dormancy process and is based on the global variable stored in the first memory, and the reporting of the effective tire pressure value can be realized, so that the problem of tire pressure false alarm in the prior art is solved, a reliable effective tire pressure value can be given to a user, and the user experience is better. Similarly, the reported information is specifically reported to a TSP platform, and the TSP platform is used for providing vehicle intelligent service for a user, and the effective tire pressure value can be issued to a mobile phone APP or other more kinds of equipment of the user through the TSP platform, including but not limited to various equipment such as an intelligent television, an intelligent watch/bracelet and the like, so that the user can know the tire pressure condition of the vehicle; after reporting is completed, the system waits for the next detection period to collect the detected tire pressure value.
In this embodiment, after the global variable in the first memory is read, the global variable may be selectively updated to the global variable stored in the first memory, so that the problem that the global variable cannot be updated later due to a long-time low-speed driving state can be avoided.
If the global variable stored in the first memory is still not in the range of 0-3.5bar, the real tire pressure is indicated to have a problem, and at this time, the tire pressure abnormality instruction can be selected to be reported, or the global variable stored in the first memory is directly reported as the effective tire pressure, and the TSP platform is used for judging whether the tire pressure abnormality exists.
Another embodiment of the present application provides a tire pressure memory reporting information processing device, including a first memory, a second memory, a processor, and a program stored in the second memory, where the processor implements the method as described above when executing the program. The first memory and the second memory are the same memory. Thereby reducing costs.
The above functions, if implemented in the form of software functional units and sold or used as a stand-alone product, may be stored in a computer readable storage medium. Based on this understanding, the technical solution of the present invention may be embodied essentially or in a part contributing to the prior art or in a part of the technical solution, in the form of a software product stored in a storage medium, comprising several instructions for causing a computer device (which may be a personal computer, a server, a network device, etc.) to perform all or part of the steps of the method according to the embodiments of the present invention.
