Problems solved by technology

When the maximum vehicle speed allowed under the load and tire pressure is exceeded, there is a risk of accelerated tire wear or even puncture
[0003] At the same time, when the vehicle speed signal comes from the vehicle speed sensor and is calculated by the vehicle controller, after exceeding 30km / h, the power supply of the central inflation and deflation system is cut off, and the use of the central inflation and deflation system is fundamentally prohibited, that is, the central inflation and deflation system is cut off. If the power supply of the system is turned off, the display function of the central inflation and deflation system will also disappear, that is, the current working status, working mode, tire pressure and other important information cannot be displayed and sent

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 As shown, a safety control system using a central inflation and deflation system includes a controller connected to: a central inflation and deflation system for performing central inflation and deflation operations and providing relevant parameters such as tire pressure; The vehicle load sensor is used to provide the vehicle load value; the vehicle speed signal detection module is used to provide the vehicle speed signal; the engine ECU is used to control the engine; the display is used to display the current parameters.

[0023] Further, the vehicle speed signal detection module includes an ABS front wheel shaft speed sensor, which is transmitted to the controller by detecting the ABS front wheel shaft speed, and the speed is converted into a vehicle speed by the controller; at the same time, the vehicle speed signal detection module can also be th...

Abstract

The invention discloses a safety control system and a control method using a central inflation and deflation system. The central inflation and deflation system is effectively controlled through steps such as power-on self-check, mode control, and parameter display; the central inflation and deflation system is controlled by a vehicle control system. The deflation system is considered uniformly. After exceeding the set speed, the display will give an early warning and alarm prompt, which fundamentally ensures the safety of the vehicle, reduces tire wear, reduces the risk of tire blowout, and effectively reminds the driver. Objective The risk of misuse is reduced. Especially for heavy vehicles, it is of great significance.

Description

technical field [0001] The invention relates to a tire central inflation and deflation control method, which belongs to the field of vehicle tire inflation and deflation control, in particular to a safety control system and control method using a central inflation and deflation system. Background technique [0002] At present, the central inflation and deflation system is used in vehicles and is a relatively independent system. It subjectively controls its functions according to the needs of the driver, such as opening, closing, inflation, deflation, pressure maintenance, and pressure measurement. The working mode of the central inflation and deflation system can be set, such as off-road, road, soft ground, etc. In each mode, the central inflation and deflation system autonomously controls the tire pressure. However, each tire has its own characteristic table (hereinafter referred to as the tire characteristic table) or tire characteristic function relationship. Under a cer...
