[0050] With the development of transportation, people have increasingly higher requirements for the intelligence of vehicles. Therefore, many vehicles are equipped with various devices to assist driving and make the ride smoother. For example, some vehicles have automatic braking control systems that can recognize road conditions, determine driving status, and control the vehicle to decelerate or stop in a timely manner under preset conditions, improving driving safety.

[0051] However, some vehicles still do not come equipped with the aforementioned automatic control systems. During operation, the driver is solely responsible for slowing down and stopping the vehicle. In emergency situations or when fatigued, the human brain may misjudge the relative speed or distance between the vehicle and obstacles ahead, leading to delayed deceleration or stopping and potentially causing accidents. Therefore, it is necessary to increase the level of automation in vehicle control to improve driving safety.

[0052] Based on the above considerations, in order to improve the automation level of vehicle braking control and enhance safety performance during driving, the inventors have researched and designed a vehicle braking control device. The vehicle braking control device provided in this application connects to the vehicle's braking components via a rotary drive mechanism to control the braking components. In emergency situations or when the driver makes an error, it can promptly decelerate or stop, ensuring braking efficiency and driving safety. Furthermore, by incorporating a position adjustment mechanism, the vehicle braking control device can adjust its size to accommodate installation on vehicles of different sizes, expanding its applicability.

[0053] The vehicle braking control device disclosed in this application can be used in vehicles, ships, or aircraft, and can be used in any transportation vehicle that needs to automatically decelerate or stop. These devices are not listed here.

[0054] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of a vehicle braking control device 100 according to some embodiments of this application. Figure 2 This is a schematic diagram of the connection between the vehicle braking control device 100 and the brake support rod 200 in some embodiments of this application. Figure 3 This is a front view of a vehicle braking control device 100 according to some embodiments of this application. Figure 4 This is a top view of a vehicle braking control device 100 according to some embodiments of this application. Figure 5 This is a left view of a vehicle braking control device 100 according to some embodiments of this application.

[0055] like Figure 1 as well as Figure 2 As shown, the vehicle braking control device 100 in this embodiment includes a rotary drive mechanism 10 and a position adjustment mechanism 20. The rotary drive mechanism 10 is connected to the vehicle's braking components, and rotates to raise or lower the brake support rod 200 of the braking components, thereby controlling the braking components to achieve vehicle braking. The position adjustment mechanism 20 includes two support rods 201 arranged opposite to each other and a crossbar 202 disposed between the two support rods 201. The rotary drive mechanism 10 is mounted on the crossbar 202, and the distance between the two support rods 201 is adjustable.

[0056] In some embodiments, the rotary drive mechanism 10 can be configured to change the moving position of the vehicle's braking components by rotation, thereby controlling the activation of the braking components and achieving control over the deceleration or stopping of the vehicle. The position adjustment mechanism 20 can adjust the position of the rotary drive mechanism 10, for example, it can change the vertical position or the horizontal position of the rotary drive mechanism 10.

[0057] In some embodiments, the support rod 201 can be arranged vertically, and the two ends of the crossbar 202 can be arranged to extend horizontally. When the distance between the two support rods 201 decreases or increases, the space occupied by the position adjustment mechanism 20 in the horizontal direction decreases or increases accordingly. Therefore, the space occupied by the braking control device can be adjusted by adjusting the distance between the two support rods 201.

[0058] In the technical solution of this application embodiment, the vehicle's braking components are controlled by a rotary drive mechanism 10, enabling timely braking in emergency situations or when the controller makes an error, ensuring braking control efficiency and driving safety. Furthermore, by providing a position adjustment mechanism 20, its size can be adjusted according to different vehicle interior spaces, adapting to installation on vehicles of different sizes and expanding the applicability of the braking control device.

[0059] In some embodiments of this application, the rotary drive mechanism 10 includes a rotary cam 101 connected to a brake support rod 200. The rotary cam 101 includes a protrusion 102 that abuts against the brake support rod 200 of the vehicle to activate the brake and achieve braking.

[0060] In the above embodiments, the rotary cam 101 can rotate about its axis, and the protrusion 102 on the rotary cam 101 protrudes radially along the axis, thus the protrusion 102 has a larger radial dimension. It is understood that the rotary cam 101 also includes a smooth portion, which has a smaller radial dimension. Therefore, when the rotary cam 101 rotates about its axis, the distance between the brake support rod 201 connected to the rotary cam 101 and the axis also changes. When the protrusion 102 is connected to the support rod 201, the distance between the axis and the brake lever is smaller, the support rod 201 is pressed down, the brake is engaged, and the vehicle decelerates or stops. When the smooth portion of the rotary cam 101 is connected to the support rod 201, the distance between the axis and the brake lever is larger, the support rod 201 rises, the brake is disengaged, and the vehicle travels normally.

[0061] In the above technical solution, the brake support rod 200 of the vehicle is controlled by setting a rotary cam 101, which has high control efficiency and is easy to install; the position adjustment mechanism 20 is equipped with a support rod 201 and a crossbar 202 to adapt to the installation of different internal space sizes, and at the same time facilitates the setting of the rotary cam 101, with a simple structure and easy operation.

[0062] In some embodiments of this application, the position adjustment mechanism 20 further includes a base 203 and a sliding device 204. The sliding device 204 includes at least one sliding part 205, which is slidably connected to the base 203; wherein, the support rod 201 includes a first support rod 206, which is connected to the sliding device 204.

[0063] The base 203 can be a plate-like structure. The base 203 is used to fix the sliding device 204 and can be made of materials with sufficient strength, such as steel or aluminum alloy plates, to ensure the stability of the support rod 201 installation, improve the accuracy of the rotary drive device's position installation, and ensure the precision of braking control. In the above structure, by setting the base 203, the stability of the position adjustment mechanism 20 installation can be improved, and the sliding device 204 can realize the sliding of the support rod 201 to adapt to the interior space of vehicles with different widths.

[0064] In some embodiments of this application, please refer to the references. Figure 3 as well as Figure 4 The position adjustment mechanism 20 further includes a fixing part 207 fixedly connected to the base 203, and the support rod 201 further includes a second support rod 208 connected to the fixing part 207. The fixing part 207 may include two opposing fixing plates, which are disposed on the base 203. The end of the second support rod 208 extends between the two fixing plates, and the two fixing plates fix the second support rod 208. In the above technical solution, by setting the fixing part 207, one end of the sliding device 204 is fixed, and by setting the second support rod 208 to the fixing part 207, the installation firmness is improved.

[0065] In some embodiments of this application, the sliding part 205 includes a sliding block 210 and a slide rail 209 extending from the first support rod 206 toward the second support rod 208, disposed on the base 203. The sliding block 210 is provided with a groove that matches the slide rail 209, and the sliding block 210 can move along the slide rail 209. In the above technical solution, the efficiency and stability of the movement of the first support rod 206 relative to the second support rod 208 are improved by setting the slide rail 209.

[0066] In some optional embodiments, the sliding part 205 further includes a sliding groove (not shown) on the base 203 and a roller on the sliding block 210. The roller slides in the sliding groove, causing the sliding part 205 to move relative to the base 203, thereby realizing the movement of the first support rod 206 relative to the second support rod 208 along the sliding groove. The above technical solution effectively improves the efficiency and stability of the movement of the first support rod 206 relative to the second support rod 208, and improves the efficiency of the position adjustment mechanism 20 in adjusting the position.

[0067] In some embodiments of this application, a connecting rod 211 is provided between the fixed part 207 and the sliding part 205. One end of the connecting rod 211, which connects to the sliding block 210, is threaded. The sliding block 210 is threadedly connected to the connecting rod 211. The end of the connecting rod 211 away from the sliding block 210 passes through the fixed plate and connects to a rotating handle 216. By rotating the rotating handle 216, the connecting rod 211 can be rotated, thereby allowing the sliding part 205 to move relative to the connecting rod 211 along its axial direction. The axis of the connecting rod 211 is parallel to the extension direction of the slide rail 209 to ensure the sliding efficiency of the sliding block 210. In the above embodiments, by setting the connecting rod 211, the distance and speed of the first support rod 206's movement are controlled, improving the accuracy of the first support rod 206's position adjustment.

[0068] In some embodiments of this application, the fixing part 207 includes a fixing block 217 disposed on the base 203, a second support rod 208 connected to the fixing block 217 via a pivot, and a first support rod 206 connected to the sliding block 210 via a pivot. Specifically, the first support rod 206 is connected to the sliding block 210 via a first pivot 213. The second support rod 208 is connected to the fixing block 217 via a second pivot 214.

[0069] In some alternative embodiments, the sliding part 205 includes two opposing sliding blocks 210, which are disposed on the base 203. At least a portion of the first rotating shaft 213 is disposed between the two sliding blocks 210, and both ends of the first rotating shaft 213 are slidably connected to the two sliding blocks 210 respectively. One end of the first support rod 206 is rotatably connected to the first rotating shaft 213. The first support rod 206 rotates about the axial direction of the first rotating shaft 213, and the rotation range of the first support rod 206 is limited by the two sliding blocks 210.

[0070] In some alternative embodiments, the fixing part 207 includes two opposing fixing blocks 217 disposed on the base 203. At least a portion of the second rotating shaft 214 is disposed between the two fixing blocks 217, and both ends of the second rotating shaft 214 are fixedly connected to the two fixing blocks 217 respectively. One end of the second support rod 208 is rotatably connected to the second rotating shaft 214. The second support rod 208 rotates about the axial direction of the second rotating shaft 214, and the rotation range of the second support rod 208 is limited by the two fixing blocks 217.

[0071] In the above technical solution, by setting a rotating shaft on the first support rod 206 and the second support rod 208, the position adjustment mechanism 20 rotates relative to the base 203 by a preset angle, thereby implementing the angle rotation adjustment of the rotation drive mechanism 10.

[0072] In some embodiments of this application, such as Figure 4As shown, the crossbar 202 has a radially penetrating movable groove 215, and the end of the first support rod 206 passes through the movable groove 215 and is slidably connected to the crossbar 202. The movable groove 215 extends along the axial direction of the crossbar 202 to limit the movement path of the end of the first support rod 206. In the above technical solution, by providing the movable groove 215, the friction of the sliding of the first support rod 206 relative to the crossbar 202 is reduced, improving the convenience and efficiency of adjusting the position of the first support rod 206.

[0073] In some embodiments of this application, both the first support rod 206 and the second support rod 208 are telescopic rods. In the above technical solution, by setting the first support rod 206 and the second support rod 208 as telescopic rods, the position adjustment mechanism 20 can be adjusted in the vertical direction.

[0074] In some embodiments of this application, such as Figure 5 As shown, the rotary drive mechanism 10 also includes a rotary motor 103. The rotary motor 103 includes a main unit and a rotating shaft connected to the main unit. The main unit is located on the crossbar 202, and the rotating shaft is connected to the rotary cam 101 and drives the rotary cam 101 to rotate around its own axis. By setting the rotary motor 103, the automatic rotation of the rotary cam 101 is realized, improving the automation level of braking control.

[0075] An embodiment of this application also provides a braking control system 1000, such as... Figure 6 As shown, the braking control system 1000 includes a vehicle braking control device 100, a sensing device 300, and a controller 400. The sensing device 300 is located on the controlled vehicle and is used to acquire vehicle speed information and distance information. The vehicle speed information includes the speed of the controlled vehicle and the speed of an obstacle vehicle in front of the controlled vehicle. The distance information includes the actual distance between the controlled vehicle and the obstacle vehicle. The controller 400 is electrically connected to both the braking control device and the sensing device 300. The controller 400 receives the aforementioned vehicle speed information and distance information and controls the activation of the braking control device based on the vehicle speed information and distance information.

[0076] In the above technical solution, the real-time driving information of the vehicle is obtained by setting up the sensing device 300, and the braking control device can be controlled according to the real-time driving information of the vehicle by setting up the controller 400, thereby improving the efficiency of braking control and driving safety.

[0077] In some embodiments of this application, such as Figure 7As shown, the sensing device 300 includes a speed sensor 301, a distance sensor 302, and an image acquisition device 303. The speed sensor 301, distance sensor 302, and image acquisition device 303 are electrically connected to the controller 400. The image acquisition device 303 includes a camera or video camera, capable of acquiring images of obstacles ahead. In the above technical solution, the speed sensor 301 and distance sensor 302 can promptly acquire the speed of the controlled vehicle and the distance between the controlled vehicle and obstacles, while the image acquisition device 303 improves the accuracy of obstacle discrimination.

[0078] In some embodiments of this application, a braking control method is also provided for controlling the braking control system 1000 in the above embodiments, such as... Figure 8 As shown, the above control method includes:

[0079] S01, Controller 400 acquires preset time T0;

[0080] S02, The sensing device 300 acquires vehicle speed information and distance information. The vehicle speed information includes the first vehicle speed V1 of the controlled vehicle and the second vehicle speed V2 of the obstacle vehicle. The distance information includes the minimum distance L1 between the controlled vehicle and the obstacle vehicle.

[0081] S03. The sensing device sends the first vehicle speed V1, the second vehicle speed V2 and the minimum distance L1 to the controller 400. The controller 400 determines the minimum reaction time T1 based on the first vehicle speed V1, the second vehicle speed V2 and the minimum distance L1, where T1 = L1 / (V1-V2).

[0082] S04, Controller 400 obtains the time difference ΔT = T1 - T0 based on the minimum response time T1 and the preset time T0;

[0083] S05. When ΔT≤0, the controller 400 sends a braking signal to the braking device to start the braking device.

[0084] In the above-mentioned braking control method, the controller 400 calculates the reaction time by acquiring the real-time relative speed and relative distance between the controlled vehicle and the obstacle vehicle, thereby improving the accuracy of the braking control system 1000 in controlling the controlled vehicle.

[0085] In some embodiments of this application, the preset time T0 ranges from 1.0s to 3.0s. By setting a reasonable reaction time, the accuracy of braking control can be guaranteed while reducing the probability of misoperation.

[0086] In some embodiments of this application, before the controller 400 obtains the preset time step, the following steps are further included:

[0087] S001. Connect the rotating cam 101 of the vehicle braking control device 100 to the brake support rod 200 of the controlled vehicle.

[0088] S002. Rotate the cam 101 clockwise or counterclockwise. When the braking is 0%, record the initial rotation angle ω1 of the cam 101. When the braking is 100%, record the maximum rotation angle ω2 of the cam 101.

[0089] In the above technical solution, the braking control system 1000 is matched with the braking device of the controlled vehicle through a pre-adaptation step, thereby improving the efficiency and accuracy of control.

[0090] In some embodiments of this application, the sensing device 300 acquires distance information specifically including:

[0091] S021, The sensing device 300 acquires a preset image;

[0092] S022. The sensing device 300 acquires an image of the object in front and compares it with a preset image. If the overlap between the image of the object in front and the preset image exceeds 85%, the object in front is determined to be an obstacle vehicle.

[0093] S023, The sensing device 300 acquires the minimum distance L1 between the controlled vehicle and the obstacle vehicle.
