Embodiment Construction

[0041]A kind of tire pressure monitoring system actual vehicle performance test system of the present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0042] A real vehicle performance test system of a tire pressure monitoring system includes an actuator and a controller. Among them, the actuator measures the internal pressure of all tires in real time, and sends the pressure signal to the controller, and realizes the tire pressure signal under the driving state under the control of the control signal of the controller. The controller receives the tire pressure signal sent by the actuator, processes it according to the set control flow, sends the control signal to the actuator, controls the action of the actuator, and completes the measurement and pressure adjustment of the tire pressure.

[0043] In this embodiment, the actuator includes a wheel assembly and a pressure adjustment assembly. The wheel assembly passes through t...

Abstract

The invention belongs to the technical field of automobile testing, particularly relates to a system for testing field performance of a tire pressure monitoring system (TPMS) and aims at solving the problem that field performance of an automobile cannot be tested during road driving in the prior art. The system is characterized by comprising an actuator and a controller, wherein the actuator is used for measuring the internal pressure of all tires in real time and transmitting pressure signals to the controller, and signals indicating tire pressure in a driving state are generated under the control of control signals of the controller; the controller receives the tire pressure signals sent from the actuator, the tire pressure signals are processed according to set control flow, and then control signals are sent to the actuator to control the actuator to act to complete measurement and regulation of tire pressure. According to the system provided by the invention, a tire pressure closed-loop control system based on a practical gas circuit is established by virtue of the actuator and the controller, closed-loop regulation is performed on the gas circuit according to a difference between target tire pressure and current tire pressure, and thus a driving pressure regulation function is achieved under the condition of generating no communication interference.

Description

technical field [0001] The invention belongs to the technical field of automobile testing, and in particular relates to an actual vehicle performance testing system of a tire pressure monitoring system. Background technique [0002] Tire pressure monitoring system (TPMS), as an active safety component of automobiles, has begun to attract more and more attention from the society. According to traffic accident investigations, many traffic accidents are caused by tire pressure problems (too high, too low, rapid air leakage) : When the tire pressure is too low, the friction between the tire and the ground will increase greatly, the temperature of the tire will rise sharply, the tire will become soft, and the strength will decrease, so that the sidewall of the weak part of the tire will be continuously squeezed and stretched, which will easily cause fatigue failure and occur. Flat tire. Even driving at a low speed will damage the tires, and this kind of damage has a long incubat...
