Description

Technical Field

[0001] The present invention belongs to the technical field of automotive braking control. More specifically, the present invention relates to an automotive parking braking system for improving driving comfort. The present invention also relates to a control method for the automotive parking braking system. Background Art

[0002] An automotive braking system refers to a series of specialized devices that apply a certain braking force to certain parts of an automobile (mainly the wheels) to forcibly brake them to a certain extent. The functions of the braking system are: to forcibly decelerate or even stop a moving automobile as required by the driver; to stably park a parked automobile under various road conditions (including on slopes); and to maintain a stable speed of a downhill moving automobile by braking for deceleration.

[0003] Although automotive technology has been continuously developing and the braking system has been continuously optimized and improved, technological development often tends to focus more on performance and safety improvements. Until now, in the braking and parking control process of the vast majority of vehicles, the driver has been keeping the brake pedal depressed until the vehicle comes to a complete stop, and there have been few technological innovations in terms of driver driving comfort.

[0004] Defects of the prior art:

[0005] The basic way for a driver to control the braking and parking of an automobile now is: keeping the brake pedal depressed until the vehicle comes to a complete stop.

[0006] Such a control method has two major defects:

[0007] 1. In most cases, the process of keeping the brake pedal depressed until the vehicle stops generally lasts for several seconds or even longer. During this process, the driver needs to keep the brake pedal depressed all the time. This method is both complex and time-consuming. Over time, the driver's operating experience is not good.

[0008] 2. Since the brake pedal has a reaction force on the foot and the driver needs to keep the foot in motion to control a certain force, for people who drive frequently, prolonged stepping on the pedal will cause physical discomfort and joint strain, etc., and even lead to many muscle and joint problems or diseases.

[0009] In the era of the continuous improvement of automotive intelligence, there should be a more convenient, comfortable, intelligent and less laborious braking control method and system for the driver.

[0010] Using keywords such as "improve; control; comfort; parking; braking system", the following retrieval results are obtained from the existing publicly available technical literature:

[0011] 1. Chinese Patent Document: "A Method and Device for Converting Train Braking Modes", Patent (Application) No.: 202310286791.8; The technical solution described therein is:

[0012] "Train braking mode conversion method: When the train enters the station and stops, detect whether the train speed is higher than the first specified value; if so, send an electric braking command to the vehicle through a preset control interface to control the train to enter the electric braking state; when the train speed is lower than the first specified value and greater than the second specified value in the electric braking state, determine whether the train needs to enter the coasting mode; if so, control the train to enter the coasting mode. When the train needs to brake again, send a mechanical braking command to the vehicle through the preset control interface to control the train to switch to the mechanical braking state and stop in the mechanical braking state."

[0013] The technical effect described therein is:

[0014] "Reduce the jerks when the train stops and improve the comfort of passengers."

[0015] 2. Chinese Patent Document: "Brake Calibration Method, Device, Equipment and Storage Medium for Vehicles", Patent (Application) No.: 202410946834.5; The technical solution described therein is:

[0016] "Brake calibration method, device, equipment and storage medium for vehicles; The method includes: First, control the vehicle to conduct brake test experiments under different SOC conditions; Then, determine the brake data corresponding to the vehicle under different SOC conditions according to the results of the vehicle's brake test experiments; Then, match the brake data corresponding to different SOC conditions with the standard brake data of the vehicle; Finally, when there is brake data corresponding to different SOC conditions that does not match the standard brake data of the vehicle, calibrate the vehicle's brake system."

[0017] The technical effect described therein is:

[0018] "By testing the brake data corresponding to the vehicle under different SOC conditions, and then calibrating the vehicle's brake system, the influence of SOC on vehicle braking is reduced. Furthermore, the braking effect of the vehicle under different SOC conditions is not very different, which is conducive to the driver's grasp of vehicle braking operations, improving the braking safety of the vehicle and the driving comfort of the vehicle."

[0019] However, the technical solutions described in the above technical documents, as well as the related technical solutions publicly applied in the prior art, have not been able to solve the problems and defects of "poor operation experience of drivers" and "causing physical discomfort and joint strain of drivers" existing in the prior art. Summary of the Invention

[0020] The present invention provides an automotive parking brake system for improving driving comfort, aiming to solve the problems of poor comfort experience in the braking and parking operation and the fatigue of the driver caused by long-term stepping on the brake pedal.

[0021] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0022] In the automotive parking brake system for improving driving comfort of the present invention, the vehicle includes a brake pedal, a vehicle conventional braking control module and a brake. A convenient braking module is provided on the control circuit connecting the brake pedal and the vehicle conventional braking control module; the convenient braking module calls corresponding braking force data according to the signal of the brake pedal and transmits it to the vehicle conventional braking control module.

[0023] A convenient braking button is provided in the braking system; the convenient braking button is connected to the convenient braking module through a signal circuit.

[0024] The convenient braking button adopts a hardware button, and the hardware button is arranged in the multi-functional button area of the vehicle steering wheel.

[0025] Alternatively, the convenient braking button adopts a hardware button, and the hardware button is arranged in the central control button area of the vehicle.

[0029] When the driver wants to decelerate and stop, click the convenient braking button to start the convenient braking mode, then step on the brake pedal once with an appropriate force and then release it; at this time, the vehicle convenient braking module will recognize the driver's parking intention and send the signal of this parking intention to the vehicle conventional braking control module; after receiving this signal, the vehicle conventional braking control module actively calls the braking force data and acts on the brake disc through the brake according to the default braking force data of the braking system to continuously decelerate until the vehicle stops.

[0030] The convenient braking module has the function of sending a braking force regulation signal; after judging that the driver has a parking intention, it will process this signal and issue a braking force regulation signal with a deceleration of A (m / s 2 ) according to the existing speed information.

[0031] For the braking force regulation signal described above, the deceleration value A it emits ranges from 3 to 6 m / s 2 ; within this range of the deceleration value A, the effect that the driver will not have obvious discomfort can be achieved.

[0032] By adopting the above technical solution, the present invention greatly applies the integration and intelligent technologies of the braking system, significantly reduces the operation time of the driver, improves the comfort of the driver's parking operation, enhances the safety of the operation, and obtains a more comfortable driving experience.

[0037] The following further details the specific embodiments of the present invention by describing the embodiments with reference to the drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0038] As Figure 1 shown in the structure of the present invention, it is an automotive parking braking system for improving the handling comfort. The automotive includes a brake pedal 1, a vehicle conventional braking control module 3 and a brake 2.

[0039] In order to solve the problems existing in the prior art and overcome its defects, and achieve the invention purpose of solving the problem that the comfort experience of the automotive braking and parking operation is poor and the driver is prone to fatigue due to long-term stepping on the brake pedal, the technical solution adopted by the present invention is:

[0040] As Figure 1 shown, in the automotive parking braking system for improving the handling comfort of the present invention, a convenient braking module 4 is provided on the control circuit connecting the brake pedal 1 and the vehicle conventional braking control module 3; the convenient braking module 4 calls the corresponding braking force data according to the signal of the brake pedal 1 and transmits it to the vehicle conventional braking control module 3.

[0041] The new car braking and parking convenient control system with high comfort of the present invention defines a new braking and parking mode, namely the convenient braking mode, which can complete braking and parking without the driver constantly stepping on the brake pedal. Different from the existing driving safety system, the present invention aims at the innovation of improving the driving comfort of the driver. The proposal of the present invention can be used as a basic principle and method for further adaptation, optimization, application and improvement of safety in specific vehicle models and specific scenarios to achieve a more comfortable driving experience.

[0042] The described braking system is provided with a convenient braking button 5; the convenient braking button 5 is connected to a convenient braking module 4 through a signal circuit.

[0043] The new braking and parking control system involved in the present invention includes the brake pedal, existing braking module, brake and brake disc of a vehicle in the prior art. In the existing braking system of the car, a convenient braking button 5 and a convenient braking module 4 are added, and a convenient braking mode is defined. Its specific function is: start the convenient braking mode with the convenient braking button, when identifying the driver's braking and parking intention, the convenient braking module actively adjusts the braking force until the vehicle completely stops;

[0044] The function of the convenient braking button 5 is: the driver can click the convenient braking button 5 to turn on the convenient braking mode 4, so that the vehicle control system can identify the driver's intention to brake and park. The convenient braking button 5 is the switch for whether to turn on the convenient braking mode; after starting this mode, the system will identify and judge the driver's braking and parking intention.

[0045] The function of the convenient braking module 4 is: adjust the braking force, after starting the convenient braking function, identify the driver's parking intention, simulate the signal of the driver constantly stepping on the brake pedal, and actively provide the braking force to gradually decelerate the vehicle until it stops.

[0046] The characteristics of the convenient braking mode are: the driver only needs two operations to complete parking in this mode. One action is to turn on the convenient braking mode, and the second action is to step on the brake pedal once;

[0047] Before the convenient braking button and the convenient braking module are added, the operation and technical solution for the driver to decelerate and stop are: step on the brake pedal until the vehicle completely stops. In this way, it will inevitably lead to a poor operation experience for the driver; long-term stepping on the pedal will cause physical discomfort and joint strain, etc., and even cause many muscle and joint hidden dangers or diseases.

[0048] After adding the convenient braking button 5 and the convenient braking module 4, the operation and technical solution for the driver to decelerate and stop the vehicle are as follows: Click the convenient braking button to activate the convenient braking mode, then step on the brake pedal 1 once with appropriate force and release it. At this time, the vehicle's convenient braking module 4 will recognize the driver's intention to stop and send a signal to the existing vehicle conventional braking control module 3. After receiving the signal, the vehicle conventional braking control module 3 actively calls the braking force and continuously decelerates according to the system default braking force until the vehicle stops.

[0049] This invention is applied to automobiles and can be used as a basic system and principle to achieve the following scenarios: During the process of braking and stopping the vehicle, after activating the convenient braking mode and when the road conditions in front of the vehicle are normal, the driver only needs to step on the brake pedal once, and the vehicle can achieve automatic parking without continuous stepping. This mode not only makes the parking operation convenient but also conforms to the ergonomics of normal driving. The driver only needs to perform two operation actions: turn on the convenient braking mode → step on the brake pedal once, and the vehicle can completely stop.

[0050] During the parking process of this convenient braking mode, there is no longer a need to continuously step on the brake pedal with the foot, which greatly reduces the driver's operation time, liberates the feet, improves the comfort of the driver's parking operation, and makes great use of the integration and intelligent technology of the current braking system.

[0051] The following are several setting forms of the convenient braking button 5, which can be selected and applied during the implementation of the technical solution:

[0052] 1. The convenient braking button 5 is a hardware button, and the hardware button is set in the multifunctional button area of the car steering wheel.

[0053] 2. The convenient braking button 5 is a hardware button, and the hardware button is set in the central control button area of the car.

[0054] 3. The convenient braking button 5 is a software button, and the software button is set on the car central control screen.

[0055] 4. The convenient braking button 5 is a software button, and the software button is set in the function area of the car instrument panel.

[0056] In order to achieve the same invention purpose as the above technical solution, the present invention also provides a control method for the vehicle parking braking system that improves the handling comfort, and its technical solution is:

[0057] When the driver wants to decelerate and stop, click the convenient braking button 5 to activate the convenient braking mode, then step on the brake pedal 1 once with appropriate force and release it; at this time, the vehicle convenient braking module 4 will recognize the driver's parking intention and send the signal of this parking intention to the vehicle conventional braking control module 3; after receiving this signal, the vehicle conventional braking control module 3 actively calls the braking force data and acts on the brake disc through the brake 2 according to the braking force data defaulted by the braking system to continuously decelerate until the vehicle stops.

[0058] The described convenient braking module 4 will only take effect after this function is turned on with the convenient braking button 5; the function of the convenient braking module 4 is to identify and judge the driver's parking intention and convert this signal into a braking force regulation signal and send it to the existing braking control module 3 of the vehicle. The existing braking module 3 starts to provide continuous braking force to simulate the operation of the driver stepping on the pedal all the time until it stops completely;

[0059] The described convenient braking module 4 defines a new operation and a new mode of braking, and it has the function of identifying and judging the driver's parking intention. When the convenient braking module 4 is activated and the driver steps on the brake pedal once with appropriate force, when these two situations occur together, it will judge that the driver has the parking intention and further process this signal.

[0060] The described convenient braking module 4 has the function of sending a braking force regulation signal; after judging that the driver has the parking intention, it will process this signal and issue a braking force regulation signal with a deceleration of A (m / s 2 ) according to the existing speed information.

[0061] For the issued braking force regulation signal, the deceleration A value ranges from 3 to 6 m / s 2 ; the deceleration A value within this range can achieve the effect that the driver has no obvious discomfort.

[0062] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting 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.
