Tire pressure detection system with built-in start loader and update method thereof

The invention relates to a tire pressure detector and a updating method thereof, in particular to a tire pressure detecting system capable of directly and conveniently updating a built-in starting loader for resetting various setting requirements, and applying the tire pressure detecting method. System update method.

The tire pressure detection of vehicle tires has entered the era of the tire tire pressure monitoring system (TPMS, TIRE PRESSURE MONITORING SYSTEM). TPMS has a significant impact on improving vehicle safety. Because the tire is the only part of the vehicle and the road surface that is in direct contact. Excessive inflation or under-inflated tires will not only affect the energy consumption and operation of the vehicle, but many accidents will also occur due to the occurrence of tire pressure. Therefore, TPMS has gradually become one of the necessary equipment for vehicles in various countries.

The current TPMS mainly consists of four parts: the tire pressure detecting component, the receiver, the display device and the update setting component. The installation of the vehicle and the use of the driver are mostly three parts of the tire pressure detecting element, the receiver and the display device. The definition settings for the tire pressure detecting component detection, different vehicle type setting requirements (for example, tire temperature, pressure, acceleration, etc.) and different vehicle type signals are performed by updating the setting components. This update setting component is It is mainly operated by the original factory setting or maintenance service personnel. When the setting component is correctly set to the tire pressure detecting component, the tire pressure detecting component can be transmitted to the receiver through the RF high frequency data signal. The receiver can pass these to the display device, and the driver can know the tire pressure condition at any time through the display of the display device.

In the past, the update setting component was operated by the original factory setting or maintenance service personnel. Although it was not difficult to operate due to lack of experience, in the Micro Control Unit (MCU) in the tire pressure detecting component, because of the function and low cost. Considering and preventing the settings in the Boot Block from being modified, the vehicle and tire pressure demand settings are usually fixed in the random memory of the tire pressure detecting component, and the starting area of the random memory is prohibited. Write processing. Therefore, the technology of the tire pressure detecting component is that it is not allowed to update the boot loader in the starting area. However, as vehicle models and models continue to evolve, if the basic output input system of the loader itself or the associated set values do not match the new vehicle hardware resources and must be modified, the past practice must initialize the memory. This mechanism of initializing the memory can perform the write reset process, which causes inconvenience to the original factory setting or service personnel. At present, in addition to being returned to the original factory for maintenance, there is no simple way in the market to update the random memory arbitrarily without being limited by the boot loader in the starting area. Therefore, the conventional product cannot be used with the vehicle model. Types and needs facilitate the updating of settings in random memory.

Wherein, the update setting component selects any reset module to cover the built-in memory segment through the standby boot loader.

Therefore, the tire pressure detecting system of the built-in boot loader of the present invention can select any reset module to cover the built-in memory segment at any time by updating the setting component. Since the random memory body contains a spare boot loader, the present invention Resetting the storage action does not affect the startup function, it is a system that can continuously update the vehicle settings and operate conveniently.

Another embodiment of the structural aspect of the present invention is a tire pressure detecting system with a built-in starter loader, which includes a tire pressure detecting element, and the tire pressure detecting element includes a random memory. The random memory body includes a spare start loader and a built-in memory segment, and the built-in memory segment can reset and store a reset module, and the standby boot loader resets the reset module for the built-in memory segment. Since the standby start loader of the present invention is not affected by the old and new reset modules, the tire pressure detecting system can be replaced by the standby start loader at any time. New setting, and the reset module can be selected to cover the built-in memory segment. Since the random memory contains a spare start loader, the reset storage action of the present invention does not affect the startup function, and is indeed a sustainable Update the system that is set and easy to operate.
