Embodiment Construction

[0056] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0057] This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

[0058] like figure 1 As shown, the present invention discloses an anti-rollover device for air-braked heavy-duty vehicles, including an anti-yaw module, an anti-roll module, an electronic control unit ECU, a yaw rate sensor, and a vehicle body roll angle sensor;

[0059] The anti-yaw module includes a main air storage tank, a brake valve, an electric push rod, a relay valve, an air compressor, and first to fourth brake units;

[0060] The first to fourth brake units are respectively...

Abstract

The invention discloses a rollover prevention device of a pneumatic braking heavy vehicle, and a control method. The rollover prevention device comprises an anti-yaw module, an anti-roll module, an electronic control unit (ECU), a yaw angular velocity sensor and a vehicle body roll angle sensor; the ECU controls the anti-yaw module to braking parts of wheels through solenoid valves mounted in front of braking gas chambers of all the wheels based on pneumatic braking, thus the anti-yaw moment is obtained, and the yaw stability of the heavy vehicle is improved; and meanwhile, the ECU controls the anti-roll module to work, high-pressure gas remaining in the braking gas chambers after braking is recovered, the recovered high-pressure gas is sprayed out towards the left side or the right side of a vehicle body through a first switching valve and a second switching valve, and the vehicle body roll angle is decreased through counter-acting force of the high-pressure gas. The structure is simple, mounting is easy, meanwhile yaw motion and roll motion of the heavy vehicle are controlled, braking energy recovery and vehicle rollover prevention are combined together, thus energy is saved, andthe rollover prevention effect is good.

Description

technical field [0001] The invention relates to the field of active safety for driving heavy vehicles, in particular to an anti-rollover device and a control method for air braking heavy vehicles. Background technique [0002] Vehicle rollover is a very serious traffic accident, which has received more and more attention in recent years. Car rollover accounts for a small proportion of traffic accidents, but it causes a high death rate and huge losses, ranking second only to car collision accidents. Among them, heavy vehicles are more prone to rollover due to their high center of gravity and large mass. Therefore, the present invention proposes a device and method for preventing rollover of heavy vehicles based on air pressure braking. [0003] At present, there are also many anti-rollover devices for automobiles. Among them, Jing Yajie proposed an emergency safety device and method for anti-rollover of automobiles (public number: CN206623830U). As an emergency safety devic...
