Description

Technical Field

[0001] The present invention relates to the technical field of suspension control, in particular to an external control device for emergency lifting when the suspension loses control. Background Art

[0002] As a primary means of transportation in modern society, automobile safety is paramount. Among a car's many systems, the suspension plays a crucial role. Connecting the vehicle body to the wheels, it not only cushions the impact of the road, ensuring a smooth ride, but also ensures good contact between the wheels and the road, providing strong support for vehicle handling and stability. A properly functioning suspension system ensures stable driving in all road conditions, from smooth highways to rugged country roads.

[0003] However, when the suspension system loses control, the consequences can be disastrous. Suspension failure can be caused by a variety of factors, including component aging, sudden mechanical failure, and severe external impact. Once the suspension loses control, the vehicle's driving posture can instantly become uncontrolled, with the vehicle body potentially experiencing severe shaking, tilting, or even rollover, significantly increasing the risk of injury to occupants and collision with other objects. Traffic accident statistics show that suspension failures are responsible for a significant number of serious accidents, often resulting in significant casualties and property damage.

[0004] For example, the Chinese utility model patent application number 202420799805.6 discloses a one-button control lifting system for the semi-trailer air suspension, which has a scientific design, a reasonable structure, and simple operation. It can control the lifting and lowering of the semi-trailer air suspension with one button, making it convenient to control the height of the semi-trailer body. However, the device still has certain defects.

[0005] When the suspension is out of control, it cannot be adjusted in time. When encountering a large pothole, the wheels may deviate from the normal driving trajectory due to the sudden violent vibration, causing the body to lose balance, and then cause the vehicle to skid or even roll.

[0006] Therefore, we propose an external control device for emergency lifting used in case of suspension loss of control, in order to solve the problems mentioned above. Summary of the Invention

[0043] The sensor system and the vehicle acceleration monitoring system are connected to the controller 4, which includes a data acquisition, a historical database and an analysis and judgment module. The analysis and judgment module is connected to the remote control system. The remote control system and the analysis and judgment module are both connected to the vehicle body drive system. The data acquisition and analysis and judgment modules are both connected to the fault diagnosis system, and the fault diagnosis system is connected to the associated equipment terminal.

[0044] The analysis and judgment module is connected to the fault alarm system and the brake assist system.

[0045] The sensor system includes a height sensor module and an angle sensor module, and the vehicle acceleration monitoring system includes an acceleration sensor. Both the sensor system and the vehicle acceleration monitoring system are equipped with monitoring thresholds, which can accurately monitor the height changes of the vehicle suspension, the body angle and acceleration data, and provide accurate data support for timely detection of abnormal situations such as suspension loss of control, so that the equipment can respond quickly and ensure vehicle driving safety.

[0046] Controller 4 collects abnormal data monitored by the sensor system and the vehicle acceleration monitoring system, and stores the data in a historical database. Then, the collected data is compared with the data in the historical database through the analysis and judgment module to draw a conclusion on the suspension out of control. The data collection, storage and analysis and judgment functions of controller 4 compare the abnormal data monitored by the sensor with the historical database to draw a conclusion on the suspension out of control, providing a decision-making basis for subsequent emergency processing, ensuring that the equipment can accurately judge the suspension status, and promptly initiate corresponding emergency measures to avoid the occurrence of dangerous situations.

[0047] The analysis and judgment module is connected to the remote control system through wireless communication technology, and the vehicle body drive system is connected to the hydraulic cylinder. The driving force in the hydraulic cylinder comes from the vehicle's own hydraulic oil source, allowing staff to remotely control the hydraulic cylinder to adjust the suspension height. When the vehicle suspension is out of control, timely remote intervention can be made to restore the vehicle body balance, avoid dangerous situations such as skidding and rolling, and ensure the safety of personnel and vehicles.

[0048] The fault diagnosis system transmits the fault data collected in the data acquisition and analysis module to the related equipment terminal through wireless communication technology, which makes it convenient for maintenance personnel to prepare maintenance plans in advance, shorten maintenance time, and improve rescue efficiency. In an emergency, staff can control external control equipment through the remote control system. The remote control system includes a mobile phone APP and a computer terminal, which can operate the equipment to complete lifting at a safe distance, making it convenient for maintenance personnel to prepare maintenance plans in advance. The mobile phone APP and computer terminals of the remote control system enable staff to operate the equipment to complete lifting at a safe distance, which not only improves rescue efficiency, reduces vehicle maintenance time and downtime losses, but also ensures the safety of maintenance personnel.

[0049] When the analysis and judgment module determines that the vehicle suspension is out of control, it transmits a signal to the fault alarm system and the brake assist system, so that the equipment can respond in time when danger occurs. Through the collaborative work of multiple systems, the risk of accidents is reduced and the safety of vehicles and personnel is guaranteed.

[0050] The fault alarm system is connected to the vehicle's hazard warning lights. The fault alarm system can trigger the vehicle's hazard warning lights to work, and the brake assist system controls the car's speed reduction, further improving the vehicle's safety when the suspension loses control. The hazard warning lights can remind surrounding vehicles and pedestrians to pay attention and avoid them. The brake assist system's speed reduction can reduce the harm caused by vehicle loss of control and reduce accident losses.

[0051] Working principle: When using the external control device for emergency lifting in case of suspension loss of control, first, the height sensor module and angle sensor module in the sensor system and the acceleration sensor in the vehicle acceleration monitoring system continue to work, monitoring the height changes of the vehicle suspension, the body angle and the acceleration data in real time. When the vehicle encounters an abnormal situation during driving, such as a suspension failure causing a sudden change in height, an abnormal body tilt angle or an abnormal fluctuation in acceleration, these sensors will transmit the monitored data to the controller 4.

[0052] The data acquisition function module of controller 4 will quickly collect these abnormal data and store them in the historical database. Then, the analysis and judgment module will extract the collected data and compare it with the data under normal conditions in the historical database. If, after comparison, the analysis and judgment module determines that the vehicle suspension is out of control, it will perform a series of operations.

[0053] On the one hand, the analysis and assessment module sends a signal to the remote control system via wireless communication technology. After the remote control system receives the signal, the staff can control the equipment from a safe distance via a mobile phone app or computer. Because the vehicle body drive system is connected to the hydraulic cylinder, and the hydraulic cylinder's driving force comes from the vehicle's own hydraulic oil source, the staff can use the remote control system or controller 4 to control the vehicle body drive system, which in turn drives the hydraulic cylinder to adjust the height of the vehicle suspension, restore the vehicle body balance, and prevent the vehicle from sliding or rolling.

[0054] On the other hand, the analysis and judgment module will transmit the signal to the fault alarm system and the brake assist system. After receiving the signal, the fault alarm system will trigger the vehicle's hazard warning lights to warn surrounding vehicles and pedestrians to avoid collision accidents. At the same time, the brake assist system starts working to control the car's speed reduction, reduce the risk of vehicle loss of control, and ensure the safety of people in the car and other road users.

[0055] The fault diagnosis system transmits fault data collected by the data acquisition and analysis module to the associated equipment terminal via wireless communication technology, allowing maintenance personnel to prepare repair plans in advance, shorten repair time, and improve rescue efficiency, thereby completing a series of tasks. Matters not described in detail in this specification represent prior art known to professionals in this field.
