Background
At present, as the pressure on environmental issues, energy issues, etc. is becoming more and more prominent, the energy consumption index, emission index, etc. for vehicles are becoming more and more stringent, which results in the engine being able to provide a lower and lower level of vacuum.

Detailed Description
First, it should be noted that the method and system for soft dead center control of an electronically controlled brake booster according to the present invention, and the steps, compositions, features and advantages of a vehicle, etc., will be described below by way of example, but it should be understood that all the descriptions are given for illustrative purposes only and thus should not be construed as limiting the invention in any way. In this document, the technical terms "first" and "second" are used for distinguishing expression purposes only and are not intended to indicate their order and relative importance, and the technical term "connected (or connected, etc)" covers that a specific component is directly connected to another component and/or indirectly connected to another component.
Furthermore, to any single feature described or implicit in an embodiment or shown or implicit in the drawings, the invention still allows any combination or permutation to continue between the features (or their equivalents) without any technical impediment, thus achieving more other embodiments of the invention that may not be directly mentioned herein. In addition, general matters that have been known to those skilled in the art are not described in detail herein.
Fig. 1 shows a basic process flow of an exemplary embodiment of a method for soft dead center control of an electronically controlled brake booster according to the invention. In this example, the soft stop control method of the electronically controlled brake booster may include the steps of:
first in step S11, the current motion parameters of the brake pedal are obtained, which may be obtained, for example, by a brake pedal displacement sensor or from a control unit, module or device (e.g., ECU, VCU, etc.) provided on the vehicle. By way of illustration, the aforementioned motion parameters of the brake pedal may include, but are not limited to, for example, position, speed, etc. of the brake pedal.
Next, in step S12, based on the current motion parameter of the brake pedal acquired in the above step, a determination may be made as to two conditions:
(1) whether a push rod in the electric control brake booster is in a return state at the moment or not;
(2) whether the current position of the brake pedal is not greater than a preset first threshold value or not;
if the above two conditions are both satisfied after the determination, the rotation speed of the motor (e.g., a brushless motor) in the electrically controlled brake booster may be reduced in step S13, so that the return speed of the push rod may be reduced until the rotation speed of the motor is reduced to a first rotation speed, and the specific value of the first rotation speed may be flexibly set according to different application requirements. Of course, if it is found that the above two conditions cannot be satisfied at this time, it may optionally return to the previous step S11 to continue to acquire the current motion parameter of the brake pedal.
Then, in step S14, the current motion parameter of the brake pedal may be newly acquired, so that in the following step S15, the following determination may be made according to the newly acquired motion parameter of the brake pedal at this time:
(1) whether a push rod in the electric control brake booster is still in a return state or not;
(2) whether the current position of the brake pedal is not greater than a preset second threshold value or not;
if the above two conditions are both satisfied, the rotation speed of the motor in the electrically controlled brake booster can be further reduced in step S16, so that the return speed of the push rod can be further reduced until the push rod is reduced to the second rotation speed (i.e. the second rotation speed will be smaller than the first rotation speed, and the specific value can be flexibly set according to different application requirements), and then the push rod can be waited to return to its initial position (i.e. zero position) in step S17. Of course, if it is found that the above two conditions cannot be satisfied at this time, it may optionally return to the previous step S14 to continue to acquire the current motion parameter of the brake pedal.
By adopting the operation steps, particularly by implementing a staged speed reduction control mode on a motor in the electric control brake booster, the return process of the push rod can be optimally controlled to achieve the purpose of realizing a soft stop point, so that the performance of the electric control brake booster in the aspects of working sound, Vibration and the like can be effectively improved on the basis of not influencing the braking performance of the whole vehicle, hardware is protected, and the increasingly improved NVH (Noise, Vibration and Harshness) requirements are met, wherein the aspects are commonly unavailable when the existing electric control brake booster is used.
It will be appreciated that, with respect to the first threshold value and the second threshold value described above, the method of the invention allows them to be preset in different applications in order to better meet the various possible practical application requirements, and that, in the same embodiment of the method according to the invention, both the first threshold value and the second threshold value are also set numerically different from each other.
In addition, one or more brake pedal displacement sensors can be provided for detecting a position parameter of the brake pedal during use, and a calculation process can be carried out on the basis of the detected change in the position of the brake pedal to determine whether the push rod in the electronically controlled brake booster is in the return position, since it can be reflected on the basis of the brake pedal position change data whether the direction of movement of the brake pedal and the push rod connected thereto is now returned toward its initial position.
In addition, it should be noted that, as an alternative, an on-board control unit disposed on the vehicle may be directly used to control the operation of the motor in the electrically controlled brake booster, for example, in the above steps S13 and S14, the on-board control unit may control to reduce the rotation speed of the motor to the first rotation speed and the second rotation speed, respectively, and such control operation does not require additional new components, which is very convenient and cost-saving. Of course, in some embodiments, the method of the present invention may also allow any suitable processor, chip, unit or module to be separately added for controlling the above operation of the electric motor in the electrically controlled brake booster.
The invention also provides a soft stop control system of the electric control brake booster. With continued reference to FIG. 2, there is shown the basic configuration of an embodiment of the soft stop control system for an electronically controlled brake booster according to the present invention.
As shown in fig. 2, the soft stop control system 100 of the electronically controlled brake booster may include an electronically controlled brake booster 10, a brake pedal 20, a sensor 30, and a controller 40. The electrically controlled brake booster 10 may be any conventional type of electrically controlled brake booster, and generally includes a motor 11 and a push rod 12, the push rod 12 being connected to the motor 11 and also to a brake pedal 20, the brake pedal 20 receiving and amplifying a braking input from a vehicle operator and transmitting the amplified braking input to the push rod 12. The sensor 30 may be any suitable type of brake pedal displacement sensor, and is not limited in number, arrangement position, specific type, and the like, and may detect and obtain the motion parameter of the brake pedal 20 through the sensor, and the specific situation of the motion parameter has been described in the foregoing, so that reference may be made to the corresponding points in the foregoing without being repeated herein.
The controller 40 may be connected to the electronically controlled brake booster 10 and the sensor 30, and may be configured to perform, for example, the steps S11 to S17 already discussed in the foregoing, and as to the specific configuration of the controller 40, the description will not be repeated again with reference to the corresponding technical contents in the foregoing.
According to the idea underlying the present invention, there is also provided a vehicle on which a soft dead center control system of an electronically controlled brake booster according to the present invention, such as that exemplified above, can be arranged, so that the advantages of the present invention, as described above, which are clearly superior to the prior art, can be fully exploited.
