Heavy-duty-car rollover-preventing system

Abstract

The invention discloses a heavy-duty-car rollover-preventing system, and relates to the technical field of heavy-duty-car safety design. The heavy-duty-car rollover-preventing system comprises a gyroscope, distance sensors, a controller, a control panel and hydraulic pressure assemblies. The gyroscope, the distance sensors, the control panel and the hydraulic pressure assemblies are connected with the controller, the gyroscope is installed at the bottom of a middle cross beam of an automobile frame, and the distance sensors are installed at the bottoms of the two sides of the automobile frame; and the hydraulic pressure assemblies are installed on the two sides of the automobile frame, and the control panel is installed in an automobile control room. In the working process, the gyroscope detects the side-lurching state of the automobile frame, the distance sensors detect the distance between the automobile frame and the road surface, and the gyroscope and the distance sensors transfer collected data to the controller; the controller analyzes the data comprehensively, and the side-lurching degree of an automobile is judged and displayed on the control panel; and a driver controls the motion of the hydraulic pressure assemblies through the control panel, balance of the automobile is kept, and the heavy-duty-car rollover-preventing effect is achieved through the technological means.

Description

technical field [0001] The invention relates to the technical field of heavy-duty vehicle safety design, in particular to a heavy-duty vehicle anti-rollover system. Background technique [0002] In recent years, the active safety of heavy-duty trucks has been paid more and more attention. For the anti-rollover of multi-axle heavy-duty truck trains, foreign countries have successively developed the Associated Braking System (Associated Braking System), the Rolling Warning Device (RWD-Rolling Warning Device), etc. ), roll stability control and support system (RSC-RSS) and other control systems, but there are some important process variables, such as brake line pressure, braking torque, etc., which cannot be measured or are difficult to measure through sensors at present.

[0002] In recent years, the active safety of heavy-duty trucks has been paid more and more attention. For the anti-rollover of multi-axle heavy-duty truck trains, foreign countries have successively developed the Associated Braking System (Associated Braking System), the Rolling Warning Device (RWD-Rolling Warning Device), etc. ), roll stability control and support system (RSC-RSS) and other control systems, but there are some important process variables, such as brake line pressure, braking torque, etc., which cannot be measured or are difficult to measure through sensors at present. or too expensive to measure

Domestic research on heavy-duty vehicle anti-rollover devices is relatively lagging behind. Due to the high cost of imported systems, the application of active anti-rollover devices on domestic heavy-duty vehicles has not yet been popularized. Therefore, it is urgent to develop heavy-duty vehicle anti-rollover devices with independent intellectual property rights.
