Description

[0002] For the transportation of metal coils, the metal coils are usually placed vertically, that is, the axis of the metal coil is horizontal. This is convenient for the hoisting and unloading of metal coils on the one hand, and on the other hand, only a part of the outermost layer of the metal coil generates friction and collision during transportation, resulting in less material loss. Currently, flatbed vehicles are mostly used to transport metal coils, and the metal coils are fixed by fixing devices to prevent the metal coils from rolling or sliding during transportation.

[0003] Due to the high quality of metal coils, often dozens of tons, and they are easy to roll in shape. When the transport vehicle encounters an emergency brake or deceleration, the metal coil is likely to break free from the fixing device and move towards the cab direction, causing a rolling accident and threatening the safety of the driver.

[0020] In this embodiment, heavy objects such as metal coils 40 are transported by a flatbed vehicle. Since the metal coils are heavy and easy to roll, the risk during transportation is relatively high, and cab 11 rolling accidents are likely to occur. Therefore, a vehicle control method and system are proposed. As Figure 2 、 Figure 3As shown, the vehicle control system may include: a first vehicle body 10, a second vehicle body 20, an avoidance assembly 30, and a heavy object 40. The first vehicle body 10 may include a cab 11, and the second vehicle body 20 may include a chassis 21, a frame 22, and a positioning block 23. The chassis 21 may be fixedly connected to the frame 22, and one side of the chassis 21 away from the ground may be movably connected to the cab 11, that is, the cab 11 may slide along one side of the chassis 21 away from the ground. The positioning block 23 may be detachably connected to the frame 22, and the positioning block 23 may abut against the heavy object 40 to limit the movement of the heavy object 40. The avoidance assembly 30 may include a vertical rotation unit 32 and a limiting unit 33. One end of the vertical rotation unit 32 may be fixedly connected to the cab 11, and the other end may be detachably connected to the limiting unit 33. Two vertical rotation units 32 may be disposed on one side of the cab 11 close to the frame 22. Two limiting units 33 may be respectively fixedly connected to the chassis 21, and the positions of the two limiting units 33 may be adapted to the positions of the two vertical rotation units 32. The vehicle control system may include a limiting state and a limit release state. The limiting state may include that the vertical rotation unit 32 and the limiting unit 33 are partially in contact, and the limiting unit 33 restricts the movement of the vertical rotation unit 32 on a plane. The limit release state may include that the vertical rotation unit 32 and the limiting unit 33 are separated, and the vertical rotation unit 32 may slide along one side of the chassis 21 away from the ground following the cab 11. As Figure 1 shown, the vehicle control method may include: Step S10, based on the heavy object 40 triggering a movement signal, the vertical rotation unit 32 on at least one side of the traveling direction of the cab 11 may be separated from the limiting unit 33. After separation, the movement of the separated vertical rotation unit 32 on a plane is not restricted, and it may slide along the plane on one side of the chassis 21 away from the ground following the cab 11.

[0021] Step S20, based on the separation of the vertical rotation unit 32 on one side of the traveling direction of the cab 11 from the limiting unit 33, as Figure 4 shown, the heavy object 40 may drive the cab 11 to rotate around the vertical rotation unit 32 on the other side. Among them, the two vertical rotation units 32 may be respectively disposed at set positions on both sides of the vehicle traveling direction. In this way, after one of the vertical rotation units 32 is separated, the cab 11 may rotate around the other vertical rotation unit 32 within a set range, so as to avoid the heavy object 40.

[0022] Step S30, based on the rotation angle of the cab 11 being greater than or equal to a set value, the vertical rotation unit 32 at the rotation center may be driven to be separated from the limiting unit 33. The set value of the rotation angle of the cab 11 is not specifically limited and may be flexibly selected according to actual situations. After the vertical rotation unit 32 at the rotation center is separated from the limiting unit 33. The movement restriction between the cab 11 and the chassis 21 is released, and the cab 11 may slide along one side of the chassis 21 away from the ground.

[0023] Step S40: Based on the vertical rotation unit 32 at the rotation center being disengaged from the limiting unit 33, the cab 11 can be disengaged from the chassis 21 and slide out towards the side front. When the heavy object 40 moves towards the cab 11, it is possible to control the vertical rotation unit 32 on at least one side of the traveling direction of the cab 11 to be disengaged from the limiting unit 33, so that the cab 11 can rotate around the vertical rotation unit 32 on the other side of the traveling direction of the cab 11 under the drive of the heavy object 40, and when the rotation angle is greater than or equal to the set value, control the vertical rotation unit 32 at the rotation center to be disengaged from the limiting unit 33. Then the cab 11 can slide out towards the side front at a certain angle relative to the traveling direction, reducing the probability that the movement path of the cab 11 coincides with the movement path of the heavy object 40. After a certain period of time, the two separate, thus enabling the driver to escape danger.

[0024] In this embodiment, step S10 includes: Step S11: Based on the heavy object 40 triggering a movement signal, the driving information on both sides of the vehicle and the movement state of the heavy object 40 can be obtained. Among them, the driving information on both sides of the vehicle may include whether there are vehicles traveling on both sides of the vehicle. When the distance between the vehicle traveling on the side and the heavy object 40 exceeds the set value, it can be considered that there is no vehicle traveling on the side. The specific size of the distance set value is not limited and can be flexibly selected according to the actual situation. For example, the distance set value can be 200 m or 300 m. The movement state of the heavy object 40 may include that the included angle between the movement trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is within the set range, or the included angle between the movement trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is greater than the set range, that is, the movement trajectory of the heavy object 40 deviates towards one side of the two sides of the vehicle traveling direction. The movement trajectory of the heavy object 40 can be used to predict the collision part between the cab 11 and the heavy object 40. According to the different collision parts, the vertical rotation unit 32 on different sides can be controlled to be disengaged from the limiting unit 33. The included angle between the movement trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 being within the set range may include that when the heavy object 40 moves towards the cab 11 until it abuts against the cab 11, the heavy object 40 can be located in the area between the two vertical rotation units 32, that is, the heavy object 40 does not collide with the vertical rotation unit 32.

[0025] Step S12: Based on the fact that there are no moving vehicles on both sides of the vehicle and the included angle between the moving trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is within a set range, it is possible to control the vertical rotation unit 32 on either side of the vehicle traveling direction to disengage from the limiting unit 33. When the vertical rotation unit 32 on one side disengages from the limiting unit 33, the cab 11 rotates around the other vertical rotation unit 32 under the drive of the heavy object 40. When the rotation angle reaches the set value, the vertical rotation unit 32 at the rotation center disengages from the limiting unit 33, and the cab 11 slides out to the side front. The movement trajectories of the cab 11 and the heavy object 40 gradually deviate, so that the driver is out of danger.

[0026] In this embodiment, controlling the vertical rotation unit 32 on either side of the vehicle traveling direction to disengage from the limiting unit 33 in step S12 may include controlling the vertical rotation unit 32 on the side of the vehicle traveling direction away from the driver to disengage from the limiting unit 33. In this way, during the process of the cab 11 rotating around the non-disengaged vertical rotation unit 32, the position of the driver always deviates from the movement trajectory of the heavy object 40, ensuring the safety of the driver. If the vertical rotation unit 32 on the side of the vehicle traveling direction close to the driver is controlled to disengage from the limiting unit 33, during the process of the cab 11 rotating around the non-disengaged vertical rotation unit 32, the position of the driver will be exposed on the movement trajectory of the heavy object 40 for a period of time, increasing the safety risk of the driver.

[0027] In this embodiment, step S10 further includes: Step S13: Based on the presence of a moving vehicle on one side of both sides of the vehicle, control the vertical rotation unit 32 on the side of the vehicle where the moving vehicle is located to disengage from the limiting unit 33. Among them, when the included angle between the moving trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is within the set range, or the included angle between the moving trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is greater than the set range and biases towards the side with the moving vehicle, by controlling the vertical rotation unit 32 on the side of the vehicle where the moving vehicle is located to disengage from the limiting unit 33, the cab 11 can rotate around the other vertical rotation unit 32 towards the side away from the moving vehicle, and slide out towards the side front after the rotation angle is greater than or equal to the set range. The cab 11 is gradually separated from the heavy object 40, and the driver is out of danger, while avoiding adverse effects on the moving vehicle. When the included angle between the moving trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is greater than the set range and biases towards the side without the moving vehicle, in order to avoid adverse effects on the moving vehicle, control the vertical rotation unit 32 on the side of the vehicle where the moving vehicle is located to disengage from the limiting unit 33; during the forward movement of the heavy object 40, the distance between the side of the heavy object 40 close to the moving vehicle and the cab 11 is less than the distance between the side of the heavy object 40 away from the moving vehicle and the cab 11. Therefore, before the heavy object 40 abuts against the non-disengaged vertical rotation unit 32, the heavy object 40 first abuts against the cab 11, pushing the cab 11 to rotate around the non-disengaged vertical rotation unit 32, and then the non-disengaged vertical rotation unit 32 disengages. The heavy object 40 drives the cab 11 to slide out along the side front, reducing the risk of the cab 11 being crushed and improving the safety of the driver.

[0028] In this embodiment, step S10 further includes: Step S14: Based on the presence of moving vehicles on both sides of the vehicle, it is possible to control the vertical rotation units 32 on both sides of the vehicle to disengage from the limiting units 33, so that the heavy object 40 can drive the cab 11 to slide along the side of the chassis 21 away from the ground.

[0029] Step S15: Based on the disengagement of the vertical rotation units 32 on both sides of the vehicle from the limiting units 33, the heavy object 40 can push the cab 11 to move. Compared with the cab 11 being fixed to the chassis 21, the risk of the cab 11 being crushed by the heavy object 40 can be reduced, and the safety of the driver during the transportation of the heavy object 40 is improved.

[0030] In this embodiment, as Figure 5 、 Figure 6 shown, step S11 includes: Step S111, based on the movement signal triggered by the heavy object 40, the lifting unit 35 can drive the rear side of the cab 11 to lift. Among them, a support plate 12 can be included between the cab 11 and the chassis 21. The lifting unit 35 can be arranged on both sides of the support plate 12 along the vehicle traveling direction. The lifting unit 35 can preferably be arranged at a position close to the rear side of the cab 11, so that the force arm is longer during the lifting process and it is more labor-saving. One end of the lifting unit 35 can be fixed to the side of the support plate 12 close to the cab 11, and the other end can be fixed to the side of the cab 11 close to the support plate 12. The edge part of the rear side of the cab 11 is usually stronger than the middle part. By driving the rear side of the cab 11 to lift, the rear side of the cab 11 is brought into contact with the heavy object 40, making the cab 11 not easily damaged and easier to be pushed forward by the heavy object 40.

[0031] Step S112, based on the rear side of the cab 11 being lifted to a set height, the vertical rotation unit 32 on at least one side of the traveling direction of the cab 11 is disengaged from the limiting unit 33. Among them, the set height includes lifting the height of the rear side of the cab 11 to a height where the rear side of the cab 11 close to the bottom of the cab 11 is greater than or equal to half of the height of the heavy object 40, so that during the contact process between the heavy object 40 and the cab 11, the heavy object 40 has an upward component force on the cab 11, further reducing the risk of the heavy object 40 crushing the cab 11.

[0032] In this embodiment, step S20 includes: Step S21, based on the vertical rotation unit 32 on one side of the traveling direction of the cab 11 being disengaged from the limiting unit 33, the strengthening fixing device between the cab 11 and the chassis 21 can be controlled to disengage, so as to avoid the strengthening fixing device between the cab 11 and the chassis 21 affecting the rotation or sliding of the cab 11.

[0033] Step S22, based on the disengagement of the strengthening fixing device between the cab 11 and the chassis 21, the heavy object 40 can drive the cab 11 to rotate around the vertical rotation unit 32 on the other side, so as to avoid the heavy object 40 and prevent the heavy object 40 from crushing the cab 11.

[0034] In this embodiment, a vehicle control system is proposed, and the vehicle control system is applied to a vehicle control method in any of the above embodiments. As Figure 2 、 Figure 3 shown, the vehicle control system can include: The first vehicle body 10, the first vehicle body 10 can include a cab 11, and the cab 11 is located at the front end of the vehicle.

[0035] The second vehicle body 20, the second vehicle body 20 may include a chassis 21, a frame 22, and a positioning block 23. The chassis 21 may be fixedly connected to the frame 22. One side of the chassis 21 away from the ground may be movably connected to the cab 11. The positioning block 23 may be detachably connected to one side of the frame 22 away from the ground.

[0036] The avoidance assembly 30, the avoidance assembly 30 may include a rearview instrument 31, a vehicle sensor, a control unit, a vertical rotation unit 32, and a limiting unit 33. The rearview instrument 31 may be detachably connected to the cab 11. The rearview instrument 31 may be used to obtain driving information on both sides of the vehicle. The driving information on both sides of the vehicle may include whether there are vehicles driving on both sides of the vehicle. When the distance between the vehicle driving on the side and the heavy object 40 exceeds the set value, it can be considered that there is no vehicle driving on the side. The specific size of the distance set value is not limited and can be flexibly selected according to the actual situation. For example, the distance set value may be 300 m. The vehicle sensor may be detachably connected to the frame 22. The vehicle sensor may be used to obtain the motion state of the heavy object 40. The motion state of the heavy object 40 may include that the included angle between the moving trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is within the set range, and the included angle between the motion trajectory of the heavy object 40 and the axis in the length direction of the second vehicle body 20 is greater than the set range, that is, the motion trajectory of the heavy object 40 deviates to one side of both sides of the vehicle traveling direction. The motion trajectory of the heavy object 40 may be used to predict the collision position between the cab 11 and the heavy object 40. According to the different collision positions, different sides of the vertical rotation unit 32 and the limiting unit 33 may be controlled to be disengaged. The control unit may be detachably connected to the chassis 21. Two limiting units 33 may be respectively fixedly connected to the chassis 21. One end of the vertical rotation unit 32 may be fixedly connected to the cab 11, and the other end may be detachably connected to the limiting unit 33. The control unit may be electrically connected to the rearview instrument 31 so as to receive the driving information on both sides of the vehicle. The control unit may be electrically connected to the vehicle sensor so as to receive the motion state information of the heavy object 40. The control unit is electrically connected to the vertical rotation unit 32, and the control unit is electrically connected to the limiting unit 33. The control unit may control the vertical rotation unit 32 and the limiting unit 33 to be disengaged according to the obtained driving information on both sides of the vehicle and the motion state information of the heavy object 40. Both vertical rotation units 32 are arranged on one side of the cab 11 close to the frame 22. The two vertical rotation units 32 are respectively arranged at set positions on both sides of the vehicle traveling direction. When one vertical rotation unit 32 and the limiting unit 33 are disengaged, the cab 11 may rotate around the other vertical rotation unit 32 along one side of the chassis 21 away from the ground so as to avoid the heavy object 40; when both vertical rotation units 32 and the limiting unit 33 are disengaged, the cab 11 may slide along one side of the chassis 21 away from the ground.

[0037] The heavy object 40, the heavy object 40 can especially include metal coils such as steel coils, which are heavy in mass and easy to roll. The heavy object 40 can be abutted against the side of the vehicle frame 22 away from the ground. The positioning block 23 can limit the movement of the heavy object 40 by abutting against the heavy object 40.

[0038] The vehicle control system can include a restricted state and a restricted release state. The restricted state can include that the vertical rotation unit 32 is partially abutted against the restriction unit 33, and the restriction unit 33 restricts the movement of the vertical rotation unit 32 on the plane. The restricted release state can include that the vertical rotation unit 32 is disengaged from the restriction unit 33, and the vertical rotation unit 32 slides along the side of the chassis 21 away from the ground following the cab 11.

[0039] In some other embodiments, a strengthening fixing device can also be included between the cab 11 and the chassis 21, so as to make the connection between the cab 11 and the chassis 21 more stable, and ensure the safety and stability during the normal driving of the vehicle. Before the heavy object 40 abuts against the cab 11, the strengthening fixing device is controlled to disengage to avoid hindering the movement of the cab 11.

[0040] In this embodiment, as Figure 5 、 Figure 6 shown, the first vehicle body 10 can also include a support plate 12. The side of the chassis 21 away from the ground can be movably connected to the support plate 12. One end of the vertical rotation unit 32 can be fixedly connected to the support plate 12, and the other end can be detachably connected to the restriction unit 33. The support plate 12 can be located between the cab 11 and the chassis 21. The support plate 12 can be detachably connected to the cab 11. When one vertical rotation unit 32 is disengaged from the restriction unit 33, the support plate 12 can drive the cab 11 to rotate around the other vertical rotation unit 32 along the side of the chassis 21 away from the ground so as to avoid the heavy object 40; when both vertical rotation units 32 are disengaged from the restriction unit 33, the support plate 12 can drive the cab 11 to slide along the side of the chassis 21 away from the ground.

[0041] The avoidance assembly 30 can also include a front rotation unit 34 and a lifting unit 35. Among the two parts of the front rotation unit 34 that rotate relative to each other, one part can be fixedly connected to the support plate 12, and the other part is fixedly connected to the cab 11. One end of the lifting unit 35 can be fixed to the side of the support plate 12 close to the cab 11, and the other end can be fixed to the side of the cab 11 close to the support plate 12. The front rotation unit 34 can be arranged on the front side of the support plate 12 along the vehicle traveling direction. The lifting unit 35 can be arranged on both sides of the support plate 12 along the vehicle traveling direction. The lifting unit 35 can drive the cab 11 to rotate around the front rotation unit 34 within a set range, so as to change the height of the rear side of the cab 11, that is, the side of the cab 11 close to the trailer. As Figure 7 、 Figure 8As shown, by setting the support plate 12, the front rotation unit 34 and the lifting unit 35, it is possible to raise the height of the rear side of the cab 11 while the cab 11 rotates around a vertical rotation unit 32, which is beneficial for the heavy object 40 to abut against a relatively strong part of the cab 11, further reducing the risk of the heavy object 40 crushing the cab 11 and improving the safety of the driver during the transportation of the heavy object 40.

[0042] In this embodiment, the vehicle control system may include an initial state and a lifting state. As Figure 3 shown, the initial state may include the cab 11 abutting against the support plate 12, and the vehicle may be in the initial state during normal driving. Taking the side of the vehicle frame 22 away from the ground as the reference plane, as Figure 6 shown, the lifting state includes that the rear side of the cab 11 rotates around the front rotation unit 34 until the height of the bottom of the rear side of the cab 11 is greater than or equal to half of the center of gravity height of the heavy object 40, so that when the heavy object 40 abuts against the cab 11, the heavy object 40 has an upward component force on the cab 11, further reducing the risk of the heavy object 40 crushing the cab 11.

[0043] Those of ordinary skill in the art can understand that the above embodiments are specific cases for implementing the present disclosure, and in practical applications, various changes can be made to them in form and details without departing from the scope of the present disclosure.
