Abstract

The invention discloses an automatic commercial vehicle tire pressure management system which comprises a controller, a plurality of vehicle tire pressure monitoring devices and at least two inflationand discharge routes, wherein the two inflation and discharge routes are of a consistent structure; the two inflation and discharge routes comprise air storage cylinders and control valve devices; air inlet ends of the air storage cylinders are communicated with an air compressor; exhaust ends of the air storage cylinders are communicated with the interior of a commercial vehicle tire through thecontrol valve devices; the output ends of the vehicle tire pressure monitoring devices are in signal connection with the input end of a controller; and the control valve devices and the control end of the air compressor are both in signal connection with the controller. Due to the design, not only is the control reliability of a system improved, but also system arrangement is facilitated, and thecost is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to an automatic tire pressure management system for commercial vehicles, which is suitable for improving the control reliability of the system. Background technique [0002] The tire pressure of a car is closely related to the driving safety of the car, and the tire pressure also affects the power and fuel economy of the vehicle. As various car manufacturers pay attention to tire pressure, more and more cars are equipped with tire pressure monitoring system. Although this system can monitor tire pressure in real time, it cannot maintain tire pressure when encountering tire leaks and other problems. However, it is impossible to adjust the tire pressure, so the car cannot be guaranteed to continue to drive normally. [0003] At present, many vehicles are equipped with tire pressure monitoring systems. Chinese patent: The invention patent with application publication num...
