Description

Technical Field

[0001] The present invention belongs to the technical field of automobile brake control. More specifically, the present invention relates to a brake system for realizing automobile braking. The present invention also relates to a control method of the brake system. Background Art

[0002] The automobile braking system refers to a series of specialized devices that apply a certain force to certain parts of the automobile (mainly the wheel brake discs) to force braking to a certain degree. The functions of the braking system are: to force the moving car to slow down or even stop according to the driver's requirements; to keep the stopped car stable under various road conditions (including on ramps); and to keep the speed of the car driving downhill stable.

[0003] In the prior art, the specific operation process of the automobile brake is as follows:

[0004] When the driver steps on the brake pedal, the existing brake control module of the car starts to operate, the brake is controlled to adjust the braking force, the brake disc begins to slow down under the force, and drives the vehicle tires to slow down until it stops.

[0005] Defects of the prior art:

[0006] Due to the problem of unstable braking in the automobile braking system, drivers and passengers feel a sense of frustration when the car stops, commonly known as the "nodding effect". Due to inertia, people in the car have unpleasant experiences such as leaning forward and swinging their heads forward. If people are to stop the car without feeling obvious discomfort and achieve "stopping the car", the driver needs to have skilled techniques, but long-term driving and careful operation each time will make the driver more tired.

[0007] Chinese patent document: "A device for solving the instability of automobile braking", patent (application) number: 202221635114.X, the technical solution and its effect recorded in it are: by changing the mechanical structure of the brake, the problem of unstable automobile braking is solved by adding a spring pump body. It can make the car easier to achieve the "brake stop" operation, that is, the driver only needs to simply step on the brake, and the vehicle can be actively braked after being processed by a spring pump body, and the driver no longer needs to have skilled technology.

[0008] However, although the braking principles of various types of vehicles are similar, the braking control systems are different. The improved method proposed in patent document 202221635114.X has a complex mechanical structure of the brake and is difficult to be truly applied to the existing braking system. To have universality, adaptability, practicality and feasibility, a system and method that is applicable to various types of braking control is required.

[0009] Therefore, the technical solutions recorded in the above-mentioned technical documents and the related technical solutions currently in public use have not been able to solve the problems and defects of "unstable braking" existing in the prior art. Summary of the invention

[0010] The invention provides a braking system for stopping a vehicle, and its purpose is to stop the vehicle smoothly and accurately.

[0011] In order to achieve the above object, the technical solution adopted by the present invention is:

[0012] The braking system for achieving automobile braking of the present invention comprises a brake pedal, a conventional brake control module and a brake, wherein the brake is installed at the wheel hub position; the brake pedal is connected to the conventional brake control module through a signal circuit; the conventional brake control module is connected to the brake through a signal circuit; and a brake control module is arranged on the signal circuit connecting the brake pedal and the conventional brake control module.

[0013] The brake control module is a hardware module or a software module.

[0014] The brake control module is connected to the speed sensor of the vehicle through a signal circuit.

[0015] The brake control module is connected to the acceleration sensor of the vehicle through a signal circuit.

[0016] The brake control module has the functions of receiving signals, analyzing signals, processing signals and issuing brake execution command signals.

[0017] The signals in the received signal, analyzed signal and processed signal include the vehicle speed signal, the vehicle acceleration signal and the braking force signal.

[0018] In order to achieve the same invention purpose as the above technical solution, the present invention also provides the above-mentioned control method of the braking system for achieving the braking of the vehicle, and its technical solution is:

[0019] When the car needs to brake and slow down until it stops, the brake control module plays a regulating role in the last short period of time when the car drops to a certain low speed, and releases pressure on the braking system to reduce the braking force, but it is still slightly greater than the braking force required to stop the car; the rate of deceleration of the car slows down until the speed is zero.

[0020] The certain low speed is the A value; the value range of the A value is between 3 and 8 km / h.

[0021] The specific numerical value of the A value is determined according to the parameters of the suspension structure, braking starting speed, vehicle center of gravity height, and vehicle weight of different models.

[0022] The present invention adopts the above-mentioned technical scheme to achieve better parking effect, and the people in the car will not have a bad experience. The car can be stopped and a better braking effect can be achieved. The driver and passengers will have a better riding experience. There will be no sense of frustration when the car is stopped, and the nodding effect is weakened; the people in the car will not have bad experiences such as leaning forward or swinging their heads forward; there is no need to excessively change the mechanical structure of the original brake of the car, and it is more universal, adaptable, practical and feasible. It is a set of general principles and basic methods applicable to various types of braking control systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic structural diagram of the braking system of the present invention. DETAILED DESCRIPTION

[0024] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0025] like Figure 1 The structure of the present invention is a braking system for achieving automobile braking, including a brake pedal, a conventional brake control module and a brake, wherein the brake is installed at the wheel hub position; the brake pedal is connected to the conventional brake control module through a signal circuit; and the conventional brake control module is connected to the brake through a signal circuit.

[0026] The system includes an existing brake control module, brake pedal, brake and tire of the automobile, and an additional brake control module. The existing brake control module refers to a module in the automobile braking system that can operate and ultimately act on the brake to adjust its braking force;

[0027] In order to achieve "brake stop", the braking system and control method of the present invention transform the brake stop operation of an experienced driver into a part of the operation of the automobile braking system. The braking system and control method can become a universal and basic guidance scheme for automobile companies when using this technology. Whether it is a gasoline vehicle or an electric vehicle, each automobile company can further develop and apply it according to the actual situation of its own hardware and software.

[0028] In order to solve the problems existing in the prior art and overcome its defects, and realize the invention purpose of braking the car smoothly and accurately, the technical solution adopted by the present invention is:

[0029] like Figure 1 As shown, the braking system for realizing automobile braking of the present invention is provided with a braking control module on the signal circuit connecting the brake pedal and the conventional braking control module.

[0030] In order to solve the problem of unstable braking of the vehicle and achieve "braking", the solution of the present invention is to add a brake control module to the vehicle braking system, so that the overall braking system of the vehicle can be divided into: the existing brake control module, the brake pedal, the brake and the tire, and the added brake control module.

[0031] In the braking system, a brake control module is added. During normal driving and regular deceleration of the car, the module does not work. It only works when the driver wants to stop the car and the car slows down to a certain speed. When the car needs to brake and slow down until it stops, the module will play a regulatory role in the last short period of time to release the braking force. The braking force will be reduced, but it is still slightly greater than the braking force required to stop the car.

[0032] After adding this module, when the car drops to a certain low speed, the brake control module begins to adjust the control power and release the pressure, so that the braking force is appropriately reduced, and the rate of deceleration of the car slows down until the speed is zero.

[0033] The basic operation process of the brake control module is that when the car slows down to a certain low speed, without the driver having to perform complicated operations, the control power is actively adjusted to release pressure and the braking force is appropriately reduced until the car stops. In this case, the nodding effect of the occupants of the car is weakened or even disappears when braking.

[0034] Compared with the braking process of the prior art, the present invention has a better parking effect by adding this module, and the passengers in the car will not have a bad experience and can achieve braking and stopping. The beneficial effects achieved are:

[0035] 1. The present invention is applied to the automobile braking system to achieve a better braking effect. The driver and passengers will have a better riding experience. There will be no sense of frustration when the car brakes, and the nodding effect will be weakened; people in the car will not have adverse experiences such as leaning forward or swinging their heads forward.

[0036] 2. There is no need to excessively change the mechanical structure of the original brake of the car, and it is more universal, adaptable, practical and feasible. It is a set of general principles and basic methods applicable to various types of brake control systems.

[0037] The brake control modules can all be carriers for adding brake stop control modules. The brake stop control modules can be placed at the front end or rear end of the existing brake modules, or can be directly integrated into them.

[0038] The brake control module is a hardware module or a software module.

[0039] The additional brake control module can be hardware or software. If the brake control module as a carrier is relatively mechanical, the control mechanism is not intelligent enough, and the degree of integration is low, it is necessary to add hardware to realize the function of the brake control module.

[0040] However, if the brake control module used as a carrier is relatively advanced, the control mechanism is intelligent enough, and the degree of integration is high, then the brake control module can be incorporated into the system as software.

[0041] The added brake control module must have the functions of receiving signals, analyzing signals, processing signals and issuing execution command signals:

[0042] The brake control module is connected to the speed sensor of the vehicle through a signal circuit.

[0043] The brake control module is connected to the acceleration sensor of the vehicle through a signal circuit.

[0044] The brake control module has the functions of receiving signals, analyzing signals, processing signals and issuing brake execution command signals.

[0045] The signals in the received signal, analyzed signal and processed signal include the vehicle speed signal, the vehicle acceleration signal and the braking force signal.

[0046] In order to achieve the same invention purpose as the above technical solution, the present invention also provides the above-mentioned control method of the braking system for achieving the braking of the vehicle, and its technical solution is:

[0047] When the car needs to brake and slow down until it stops, the brake control module plays a regulating role in the last short period of time when the car drops to a certain low speed, and releases pressure on the braking system to reduce the braking force, but it is still slightly greater than the braking force required to stop the car; the rate of deceleration of the car slows down until the speed is zero.

[0048] The certain low speed is the A value; the value range of the A value is between 3 and 8 km / h.

[0049] The specific numerical value of the A value is determined according to the parameters of the suspension structure, braking starting speed, vehicle center of gravity height, and vehicle weight of different models.

[0050] The execution command signal issued by the brake control module must have the effect of adjusting the control force. More specifically, the role of the execution command signal it sends in the process of achieving the "brake stop" is to gradually reduce the braking force from a larger value to a smaller value. This smaller value is closer to the braking force required for the car to just stop.

[0051] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
