Problems solved by technology

In addition, even if the commonly used automatic matching equipment successfully completes the matching and writing of the ID, it is difficult to confirm the correctness of the written ID, that is, the vehicle mistakenly registers and writes the tire ID of other vehicles to the vehicle when the ID is matched. In the tire, it is impossible to quickly find the wrong writing problem

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] Such as figure 2 As shown, the ID matching system of the passenger car tire pressure monitoring system includes a hand-held low-frequency trigger device 1, a left front wheel sensor 2.1, a right front wheel sensor 2.2, a right rear wheel sensor 2.3, and a left rear wheel sensor respectively installed on four wheels. Sensor 2.4 and controller 3.

[0027] Such as figure 1 As shown, the ID matching method of the passenger car tire pressure monitoring system is implemented in the matching system, and its specific control process is as follows:

[0028] The whole matching method is divided into three stages: the first stage is the M1ID acquisition stage. Before this stage, the controller has not registered for ID writing, and the status information of the controller is unregistered. At this time, the ID storage area corresponding to each t...

Abstract

The invention relates to the field of auto electronic technology and particularly relates to an ID matching method for auto tire pressure monitoring system and a system thereof. A low-frequency handheld-triggering apparatus sequentially acquires tire IDs transmitted by tire sensors in a given order, and sends the tire IDs to a controller for registration. The tire sensors transmit information of tire IDs, tire pressure and tire temperature to the controller. The controller compares the tire IDs transmitted by the tire sensors with registered tire IDs, wherein if the tire IDs are correct, the value of the tire pressure and the value of tire temperature are displayed. The low-frequency handheld-triggering apparatus is small in size and convenient to operate. In the way that the tire IDs are transmitted to the controller for registration by the apparatus, online registration in a factory is achieved and users register at home. When the low-frequency handheld-triggering apparatus acquires the tire IDs, every new tire ID is compared to the previous tire ID, accordingly multiple registration of the tire ID is avoided. The controller compares the tire IDs transmitted by the tire sensors with the registered tire IDs, accordingly a registration error is avoided.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an ID matching method and system for a passenger car tire pressure monitoring system. Background technique [0002] At present, automatic matching equipment is generally used for direct unidirectional tire pressure monitoring system ID matching on the production line. It is necessary to introduce and develop new equipment and modify the traditional production line. The cycle is long, the cost is high, and it is not easy to migrate; Matching failure rate, if the matching failed vehicle is returned to the production line for re-learning, it will lead to occupation and extension of production line man-hours, affecting efficiency. Therefore, there is a need for a matching system and method that supports both online matching and offline matching, so as to cope with the situation of production line migration, the introduction of automation equipment and the efficient and...
