Description

Technical Field

[0001] The present invention relates to the technical field of vehicle braking, and particularly to a braking design method, system, multi-axle vehicle and medium for multi-axle vehicles. Background Art

[0002] Electronically controlled braking / by-wire braking, as the basis of intelligent driving and driverless driving, can effectively improve braking performance, driving safety and the overall vehicle intelligence level, and is the application trend of braking systems. At present, the by-wire braking technology on the market is mainly developed and matched for commercial vehicles, and the number of axles of the applied models generally does not exceed 4 axles. Moreover, the corresponding electronically controlled braking / by-wire braking usually consists of a control module, an electronic control master cylinder, a front axle module valve, and one or two rear axle module valves.

[0003] However, the number of braking chambers controlled by the front axle module valve or the rear axle module valve for each axle is limited. For example, one module valve can control at most 2 groups (i.e., 4) of braking chambers, otherwise it will have an adverse impact on braking response. Therefore, the existing solutions can control at most vehicles with 3 to 6 axles; further, for some axles with a four-chamber layout, the number of axles that can be controlled correspondingly will be even less.

[0004] In summary, for multi-axle vehicles with more than 4 axles, such as all-terrain cranes with 5 to 11 axles, due to the limited number of braking chambers that can be controlled by a single module valve, the braking response time of such vehicles becomes slower, making it difficult to meet the fast braking response requirements of multi-axle vehicles. Summary of the Invention

[0005] In view of this, the present invention provides a braking design method, system, multi-axle vehicle and medium for multi-axle vehicles to solve the problems that the prior art ignores the fast braking response requirements of multi-axle vehicles, it is difficult to reasonably and effectively control the number of braking chambers equipped on multi-axle vehicles, greatly reduces the reaction time of vehicle braking, and further has an adverse impact on braking response.

[0006] In a first aspect, the present invention provides a braking design method for multi-axle vehicles, the method comprising:

[0007] Determine the number of braking chambers respectively equipped at both ends of each axle in the multi-axle vehicle;

[0008] Determine the braking design of the braking chambers equipped on the corresponding axle according to the number of braking chambers.

[0009] In view of the problem of the large number of brake chambers equipped in multi-axle vehicles in practical applications, the braking design of multi-axle vehicles is determined by the actual axles of the vehicle and the corresponding number of equipped brake chambers, which can significantly increase the number of brake chambers controlled by a single module valve, help to speed up the braking response time of multi-axle vehicles, and thus effectively avoid the adverse effects caused by braking response, greatly meeting the fast braking response requirements of multi-axle vehicles.

[0010] In an alternative embodiment, the braking design for the brake chambers equipped on the corresponding axles is determined according to the number of brake chambers, including:

[0011] Judge whether the number of brake chambers is less than a first preset threshold;

[0012] If the number of brake chambers is not less than the first preset threshold, a relay valve is added, and the relay valve is respectively connected to the corresponding brake chamber and the corresponding module valve.

[0013] The present invention determines different braking design schemes according to the size relationship between the number of brake chambers respectively equipped at both ends of each axle in a multi-axle vehicle and the set first preset threshold, which can meet the braking design requirements of multi-axle vehicles with multiple axle numbers and equipped with multiple brake chambers, increase the controllable number of brake chambers by a single module valve, not only speed up the braking response time of multi-axle vehicles, but also effectively avoid the adverse effects caused by braking response.

[0014] In an alternative embodiment, the braking design method for multi-axle vehicles further includes:

[0015] If the number of brake chambers is less than the first preset threshold, the corresponding brake chamber is directly connected to the corresponding module valve.

[0016] When the number of brake chambers respectively equipped at both ends of each axle in a multi-axle vehicle is less than the set first preset threshold, the present invention directly connects the corresponding brake chamber to the corresponding module valve, which can realize reasonable control of the number of brake chambers equipped in multi-axle vehicles and has the advantages of simple and effective design.

[0017] In an alternative embodiment, before directly connecting the number of brake chambers to the corresponding module valve, the braking design method for multi-axle vehicles further includes:

[0018] Detect the number of brake chambers respectively equipped at both ends of other axles connected to the same module valve;

[0019] If the number of brake chambers respectively equipped at both ends of all other axles is less than the first preset threshold, a relay valve is added, and the relay valve is respectively connected to the corresponding brake chamber and the corresponding module valve.

[0020] The present invention also takes into account the problem that the number of brake chambers that can be controlled by a single module valve is limited. When the number of brake chambers equipped at both ends of other axles connected to the same module valve is less than the first preset threshold, a relay valve is correspondingly added to increase the controllable number of brake chambers by a single module valve, which helps to accelerate the braking response time of a multi-axle vehicle and thus avoids the adverse effects caused by the braking response.

[0021] In an alternative embodiment, the braking design method for a multi-axle vehicle further includes:

[0022] If the number of brake chambers equipped at both ends of any other axle is not less than the first preset threshold, then perform the step of directly connecting the number of brake chambers to the corresponding module valve.

[0023] When the number of brake chambers equipped at both ends of other axles connected to the same module valve is not less than the first preset threshold, the present invention correspondingly designs to directly connect the number of brake chambers to the corresponding module valve, which can achieve a reasonable and effective braking design for the number of brake chambers equipped on a multi-axle vehicle.

[0024] In an alternative embodiment, the relay valve includes an air inlet, an air outlet, and a control port; connecting the relay valve to the corresponding brake chamber and the corresponding module valve respectively includes:

[0025] Connect the air inlet of the relay valve to a preset air storage cylinder, connect the air outlet of the relay valve to the corresponding brake chamber, and connect the control port of the relay valve to the corresponding module valve respectively.

[0026] In an alternative embodiment, after the braking design of the brake chambers equipped on the corresponding axle is determined according to the number of brake chambers, the braking design method for a multi-axle vehicle further includes:

[0027] Obtain the total number of air chambers of the brake chambers equipped at both ends of all axles connected to the same module valve respectively;

[0028] If there is any total number of air chambers greater than the second preset threshold, it indicates that the braking design of the multi-axle vehicle is unreasonable;

[0029] If all total numbers of air chambers are not greater than the second preset threshold, it indicates that the braking design of the multi-axle vehicle is reasonable.

[0030] After determining the braking design scheme of the multi-axle vehicle, the present invention also verifies whether the braking design is reasonable by designing the size relationship between the total number of air chambers of the brake chambers equipped at both ends of all axles connected to the same module valve and the set second preset threshold, which can significantly improve the rationality of the braking design.

[0031] Second aspect, the present invention provides a braking design system for multi-axle vehicles, the system comprising: a determination module configured to determine the number of brake chambers respectively equipped at both ends of each axle in a multi-axle vehicle;

[0032] a design module configured to determine the braking design of the brake chambers equipped for the corresponding axle according to the number of brake chambers.

[0033] The braking design system for multi-axle vehicles of the present invention can take into account the problem of the large number of brake chambers equipped in multi-axle vehicles in practical applications. Specifically, the corresponding braking design is determined by the number of axles of the actual multi-axle vehicle and the corresponding number of brake chambers equipped, which can significantly increase the number of brake chambers controlled by a single module valve, help to accelerate the braking response time of multi-axle vehicles, effectively avoid the adverse effects caused by braking response, and meet the fast braking response requirements of multi-axle vehicles.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] An embodiment of the present invention provides an embodiment of a braking design method for multi-axle vehicles. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0045] In this embodiment, a braking design method for multi-axle vehicles is provided. Figure 1 It is a schematic flowchart of a braking design method for multi-axle vehicles according to an embodiment of the present invention. As Figure 1 shown, the process includes the following steps:

[0046] Step S101, determine the number of brake chambers respectively equipped at both ends of each axle in the multi-axle vehicle.

[0047] It should be noted that as a functional component of the vehicle braking system, the brake chamber is used to convert the pressure of compressed air into a mechanical force that rotates the brake camshaft, thereby realizing the braking action. Common brake chambers can be divided into single-chamber brake chambers and double-chamber brake chambers according to different functions and structures. Among them, the single-chamber brake chamber is usually also called the service brake chamber, which is generally installed on the front steering axle of the vehicle and only has the service braking function. That is, during vehicle driving, when the driver steps on the brake pedal, compressed air enters the service brake chamber, pushing the diaphragm to deform, and then pushing the push rod, driving the brake adjusting arm, making the brake cam rotate, pressing the brake shoe friction lining against the brake drum, generating braking force, and realizing vehicle braking. The double-chamber brake chamber is also called the spring brake chamber with energy storage, which is widely used on the drive axle and trailer axle of the vehicle. It has two air chamber cavities inside. One is the service brake chamber, and the other is the parking brake chamber, combining the functions of service braking and parking braking. That is, during service braking, compressed air enters the service brake chamber, pushing the diaphragm to squeeze the spring to brake the vehicle. During parking braking, the air in the parking brake chamber is discharged, and the internal spring pushes the push rod to realize parking braking.

[0048] In this embodiment, the brake chamber is a service brake chamber, which is the corresponding air chamber for vehicle service braking. The specific determination method of its quantity can be determined by referring to conventional means in this field and will not be elaborated here.

[0049] Step S102: Determine the braking design of the brake chambers equipped on the corresponding axles according to the number of brake chambers.

[0050] It should be noted that aiming at the problem that in the existing vehicle braking system, the number of brake chambers that can be controlled by a single module valve is limited, and it is difficult to reasonably and effectively control the number of brake chambers equipped on multi-axle vehicles. In this embodiment, a braking design method of adding relay valves between the electronic control module and each service brake chamber is adopted to increase the number of air chambers that can be controlled by a single module valve, which has the significant advantages of simple, convenient and efficient design.

[0051] The braking design method for multi-axle vehicles in the embodiment of the present invention determines the braking design of multi-axle vehicles according to the actual axles of the vehicle and the corresponding number of brake chambers equipped, which can significantly increase the number of brake chambers controlled by a single module valve, help to shorten the braking response time of multi-axle vehicles, and thus effectively avoid the adverse effects caused by braking response, greatly meeting the fast braking response requirements of multi-axle vehicles.

[0052] In this embodiment, a braking design method for multi-axle vehicles is provided. Figure 2 It is a schematic flow chart of another braking design method for multi-axle vehicles according to the embodiment of the present invention. As Figure 2 shown, this process includes the following steps:

[0053] Step S201: Determine the number of brake chambers equipped at both ends of each axle in a multi-axle vehicle. For details, please refer to Figure 1 Step S101 of the illustrated embodiment, which will not be elaborated here.

[0054] Step S202: Determine the braking design of the brake chambers equipped on the corresponding axle according to the number of brake chambers.

[0055] Specifically, the above Step S202 includes:

[0056] Step S2021: Determine whether the number of brake chambers is less than the first preset threshold.

[0057] In this embodiment, the specific value of the first preset threshold is not specifically limited here and can be adaptively adjusted according to actual needs. For example, the first preset threshold is 2, which is only for illustrative purposes.

[0058] Step S2022: If the number of brake chambers is not less than the first preset threshold, add a relay valve and connect the relay valve to the corresponding brake chamber and the corresponding module valve respectively.

[0059] It should be noted that a relay valve is a valve used in a pneumatic braking system, which mainly functions to accelerate inflation, deflation or control the air pressure, etc., to improve the response speed and performance of the braking system. In this embodiment, the relay valve includes an air inlet, an air outlet and a control port. Therefore, connecting the relay valve to the corresponding brake chamber and the corresponding module valve in the above steps includes: connecting the air inlet of the relay valve to a preset air storage cylinder, connecting the air outlet of the relay valve to the corresponding brake chamber, and connecting the control port of the relay valve to the corresponding module valve. Specifically, by connecting the air inlet of the relay valve to the air storage cylinder and the air outlet to the brake chamber, when the brake pedal is depressed during actual vehicle driving, the output air pressure of the brake valve is input as the control pressure of the relay valve. Under the action of the control pressure, the intake valve is pushed open, and then the compressed air directly enters the brake chamber from the air storage cylinder through the air inlet without flowing through the brake valve, which greatly shortens the charging pipeline of the brake chamber and accelerates the inflation process of the chamber.

[0060] It should be explained that the preset air storage cylinder is used to provide compressed air, and the specific number of its settings can be adaptively adjusted according to actual needs; the module valve is a valve system that integrates multiple valves or related functional elements in a compact structure, and its specific type is determined adaptively based on actual needs; for example, the front axle module valve in an electronically controlled braking / electronically controlled by wire braking system is a single-channel actuator, with port 1 connected to the air source, port 3 as the exhaust port, and port 4 connected to the output of the foot valve for the front axle; specifically, to achieve independent control of the left and right front wheels, the two output air paths (i.e., port 2) of the front axle module valve are respectively connected to the ABS solenoid valves of the left and right front wheels; the module adjusts the air pressure at the control port and the output air pressure of the relay valve by controlling the intake and exhaust solenoid valves.

[0061] In practical applications, since the relay valve is also called the acceleration valve, in this embodiment, a new relay valve is added as a relay amplifier for the air circuit to receive the low-flow control signal of the module valve, and then quickly open the large-aperture valve to directly transport the high-pressure air in the air storage tank to the corresponding air chamber, which can effectively avoid the response delay caused by the module valve directly driving the large-flow air circuit; and since the output signal of a single module valve can trigger multiple relay valves at the same time, in this embodiment, each relay valve can independently control a group of air chambers, and then connect it to a single module valve, which can achieve the "one-to-many" control logic. Therefore, when the number of vehicle axles increases, through the braking design for multi-axle vehicles in this embodiment, there is no need to increase the expensive electronic control unit in proportion. Only by adding relay valves, the system cost and reliability can be optimized while maintaining the braking performance.

[0062] In summary, in the embodiment of the present invention, different braking design schemes are determined by the size relationship between the number of braking air chambers respectively equipped at both ends of each axle in a multi-axle vehicle and the set first preset threshold, which can meet the braking design requirements of multi-axle vehicles with multiple axle numbers and equipped with multiple braking air chambers, can increase the controllable number of braking air chambers by a single module valve, not only speeds up the braking response time of multi-axle vehicles, but also effectively avoids the adverse effects caused by braking response.

[0063] Step S2023, if the number of braking air chambers is less than the first preset threshold, directly connect the corresponding braking air chamber to the corresponding module valve.

[0064] In the embodiment of the present invention, when the number of braking air chambers respectively equipped at both ends of each axle in a multi-axle vehicle is less than the set first preset threshold, directly connect the corresponding braking air chamber to the corresponding module valve, which can realize the reasonable control of the number of braking air chambers equipped in the multi-axle vehicle and has the advantages of simple and effective design.

[0065] It should be noted that since the number of braking air chambers that can be controlled by a single module valve is limited, before directly connecting the number of braking air chambers to the corresponding module valve, the braking design method for multi-axle vehicles in this embodiment further includes:

[0066] Step A1, respectively detect the number of braking air chambers equipped at both ends of other axles connected to the same module valve.

[0067] Step A2, if the number of braking air chambers equipped at both ends of all other axles is less than the first preset threshold, add a relay valve, and connect the relay valve to the corresponding braking air chamber and the corresponding module valve respectively.

[0068] When the number of brake chambers equipped at both ends of other axles connected to the same module valve in the embodiments of the present invention is less than the first preset threshold, a relay valve is correspondingly added to increase the controllable number of brake chambers by a single module valve, which helps to accelerate the braking response time of multi-axle vehicles and thus avoids the adverse effects caused by braking response.

[0069] Step A3, if the number of brake chambers equipped at both ends of any other axle is not less than the first preset threshold, then execute the step of directly connecting the number of brake chambers to the corresponding module valve.

[0070] When the number of brake chambers equipped at both ends of other axles connected to the same module valve in the embodiments of the present invention is not less than the first preset threshold, a corresponding design is made to directly connect the number of brake chambers to the corresponding module valve, which can achieve a reasonable and effective braking design for the number of brake chambers equipped on multi-axle vehicles.

[0071] It should be noted that after obtaining the corresponding braking design of the multi-axle vehicle in this embodiment, it is also necessary to verify the rationality of the overall design. Therefore, after determining the braking design of the brake chambers equipped on the corresponding axle according to the number of brake chambers, the braking design method for multi-axle vehicles in this embodiment further includes:

[0072] Step B1, respectively obtain the total number of air chambers of the brake chambers equipped at both ends of all axles connected to the same module valve.

[0073] Step B2, if there is any total number of air chambers greater than the second preset threshold, it indicates that the braking design of the multi-axle vehicle is unreasonable.

[0074] In this embodiment, the specific value of the second preset threshold is not limited here and is adaptively adjusted according to the connection attributes of the actual module valve.

[0075] Step B3, if all the total numbers of air chambers are not greater than the second preset threshold, it indicates that the braking design of the multi-axle vehicle is reasonable.

[0076] After determining the braking design scheme of the multi-axle vehicle in the embodiments of the present invention, it also verifies whether the braking design is reasonable by designing the size relationship between the total number of air chambers of the brake chambers equipped at both ends of all axles connected to the same module valve and the set second preset threshold, which can significantly improve the rationality of the braking design.

[0077] In a specific embodiment, Figure 3It is a schematic diagram of the braking system composition of a four-axle vehicle. As can be seen from the figure, the braking system includes a control module, an electronic master cylinder, a front axle module valve, and two rear axle module valves; among them, serial number 1 is the electronic master cylinder, serial number 2 is the front module valve, serial number 3 is the control module, serial number 4 is the first rear axle module valve, serial number 5 is the service air chamber, and serial number 6 is the second rear axle module valve; the meanings of the corresponding port serial numbers of the electronic master cylinder, the front axle module valve, and the rear axle module valve in the figure are respectively: the "1" port is the air inlet, the "2" port is the air outlet, and the "4" port is the control port; in addition, the above braking system includes two braking methods: electronic control braking and wire control braking. Under normal circumstances, the electronic control braking method is adopted (that is, the red route in the figure), and when the electronic control fails, the air control braking method is adopted (that is, the green route in the figure).

[0078] Since one module valve can control at most 2 groups (i.e., 4) of braking air chambers, for multi-axle vehicles with two (i.e., vehicles with more than 4 axles), the Figure 3 adopted braking design will have an adverse impact on the braking response of the vehicle. Therefore, in this embodiment, by adding a relay valve between the electronic control module and the air chamber, the number of air chambers that a single module valve can control is increased. Taking a nine-axle vehicle as an example in this embodiment, Figure 4 It is a schematic diagram of the braking system composition of the embodiment of the present invention for multi-axle vehicles. As can be seen from the figure, the braking system includes a control module, an electronic master cylinder, a front axle module valve, two rear axle module valves, and multiple relay valves; among them, serial number 1 is the electronic master cylinder, serial number 2 is the front module valve, serial number 3 is the control module, serial number 4 is the first rear axle module valve, serial number 5 is the service air chamber, serial number 6 is the second rear axle module valve, and serial number 7 is the relay valve. The meanings of the corresponding port serial numbers of the electronic master cylinder, the front axle module valve, the rear axle module valve, and the relay valve in the figure are respectively: the "1" port is the air inlet, the "2" port is the air outlet, and the "4" port is the control port; among them, the "1" port of the relay valve is directly connected to the air storage tank. Therefore, the module valve can output only the control air from the "2" port. The control air only needs to reduce the pressure of the control pipeline. Therefore, the air volume output from the "2" port of the module valve can be greatly reduced, thereby increasing the number of air chambers that a single module valve can control.

[0079] Refer to Figure 4 It should be noted that a single module valve in this embodiment can directly control a group of air chambers (such as the six-axle shown in the figure), or can indirectly control the air chambers completely by controlling the relay valve (such as the first, second, and third axles, or the seventh, eighth, and ninth axles shown in the figure); among them, the design concept that the module valve is not directly connected to the air chamber or is connected to the air chamber as little as possible, the relay valve draws air from the air storage tank alone, and controls the air chamber by controlling the relay valve should be followed. It should be noted that for the number of axles included in an actual vehicle and the number of service air chambers equipped, in order to ensure the timely response of vehicle braking, the braking design method for multi-axle vehicles in this embodiment can be used for adaptive design.

[0080] In summary, the braking design method for multi-axle vehicles according to the embodiments of the present invention can increase the controllable number of brake chambers by a single module valve, thereby accelerating the braking response time of multi-axle vehicles. It not only effectively avoids the adverse effects caused by braking response, meets the rapid braking response requirements of multi-axle vehicles, but also helps to improve the intelligent level of multi-axle vehicles.
