The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0032] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples.

[0033] Reference below Figure 1-Figure 5 A dump truck 100 with an oil circuit control function according to an embodiment of the present application is described.

[0034] It is understood that a dump truck, also known as a tipping truck, is a vehicle that unloads cargo by itself through hydraulic or mechanical lifting. It should be noted that, unless otherwise specified, the front and rear directions shown in this article are the length direction of the dump truck, the up and down directions are the height direction of the dump truck, and the width direction is the left and right direction of the dump truck, where the front refers to the forward direction of the dump truck.

[0035] In some usage scenarios, the driver can control the lifting degree of the hydraulic lifting mechanism 30 by stepping on the accelerator pedal 60, and then control the flipping angle of the cargo box 20. For example, the greater the degree of stepping on the accelerator pedal 60, the greater the lifting degree of the hydraulic lifting mechanism 30, that is, the greater the flipping angle of the cargo box 20. Conversely, the smaller the degree of stepping on the accelerator pedal 60, the smaller the lifting degree of the hydraulic lifting mechanism 30, that is, the smaller the flipping angle of the cargo box 20.

[0036] However, during the flipping process of the cargo box 20 , since the environment on the rear side of the cargo box 20 is difficult to observe, there is a risk that the cargo box 20 hits an obstacle, thereby causing damage to the cargo box 20 .

[0037] In this regard, the present application proposes a dump truck 100 with an oil circuit control function, please refer to Figure 1 The dump truck 100 with oil circuit control function includes: a chassis 10 and a cargo box 20.

[0038] The wheels are rotatably mounted on the chassis 10, the cargo box 20 is connected to the chassis 10 through a hydraulic lifting mechanism 30, so that the cargo box 20 can be turned over by using the hydraulic lifting mechanism 30, the control device 40 is mounted on the chassis 10, the touch device 50 includes a sensing element 51 and an oil circuit control element 52, the sensing element 51 is connected to the cargo box 20 and is used to sense obstacles, and the oil circuit control element 52 is arranged on the oil circuit 61 of the accelerator pedal 60 of the dump truck 100 with an oil circuit control function and is used to control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60, such as Figure 2 As shown, the control device 40 is electrically connected between the sensing component 51 and the oil circuit control component 52; wherein, when the cargo box 20 tips backward relative to the chassis 10, the control device 40 continuously obtains the status information of the sensing component 51, and the control device 40 controls the operation of the oil circuit control component 52 according to the status information.

[0039] For example, the sensing element 51 may be a pressure sensor 512 or an infrared rangefinder, etc. The sensing element 51 may be used to sense obstacles by pressure changes between the sensing element 51 and the obstacle or distance information between the sensing element 51 and the obstacle, etc., which is not limited here.

[0040] For example, the oil circuit control element 52 may be an electronic switch valve, such as Figure 2 As shown, the electronic switch valve can be used to control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60. It can be understood that when the oil circuit 61 of the accelerator pedal 60 is in a connected state, the accelerator pedal 60 can work normally, and when the oil circuit 61 of the accelerator pedal 60 is in a disconnected state, the accelerator pedal 60 fails.

[0041] The control device 40 may be a controller. When the cargo box 20 tips backward relative to the chassis 10, the control device 40 continuously obtains status information of the sensing component 51, and the control device 40 controls the action of the oil circuit control component 52 according to the status information. In this way, when the cargo box 20 tips backward relative to the chassis 10, the control device 40 may control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60 according to the status information of the sensing component 51, thereby reducing the risk of the cargo box 20 colliding with an obstacle when the cargo box 20 tips backward relative to the chassis 10, thereby reducing damage to the cargo box 20. At the same time, such a control method does not require human observation, which is conducive to reducing the difficulty of operation and improving control accuracy.

[0042] According to the dump truck 100 with oil circuit control function in the embodiment of the present application, its sensor 51 is connected to the cargo box 20, the oil circuit control component 52 is arranged on the oil circuit 61 of the accelerator pedal 60 of the dump truck 100 with oil circuit control function and is used to control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60, and the control device 40 is electrically connected between the sensor 51 and the oil circuit control component 52. In this way, when the cargo box 20 tilts backward relative to the chassis 10, the control device 40 can control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60 according to the status information of the sensor 51, thereby reducing the risk of the cargo box 20 colliding with obstacles when the cargo box 20 tilts backward relative to the chassis 10, thereby reducing damage to the cargo box 20.

[0043] In some embodiments, the state information of the sensor 51 includes touch information when the sensor 51 contacts an obstacle, and the control device 40 controls the oil circuit control component 52 to disconnect the oil circuit 61 of the accelerator pedal 60 according to the touch information.

[0044] It can be understood that when the sensing element 51 contacts an obstacle, a touch message is sent out, and the control device 40 controls the oil circuit control element 52 to operate according to the touch message to disconnect the oil circuit 61 of the accelerator pedal 60. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensing element 51 contacts an obstacle, the oil circuit 61 of the accelerator pedal 60 will be disconnected. At this time, the cargo box 20 will remain at the current flipping angle, and the driver can no longer control the flipping of the cargo box 20 through the accelerator pedal 60, thereby reducing the risk of the cargo box 20 hitting an obstacle when the cargo box 20 tilts backward relative to the chassis 10, thereby reducing damage to the cargo box 20.

[0045] In some embodiments, the state information of the sensing element 51 includes separation information when the sensing element 51 is separated from the obstacle, and the control device 40 controls the oil circuit control element 52 to operate to connect the oil circuit 61 of the accelerator pedal 60 according to the separation information.

[0046] It can be understood that when the sensing element 51 is separated from or not in contact with an obstacle, a separation message is sent out, and the control device 40 controls the oil circuit control element 52 to move the oil circuit 61 connected to the accelerator pedal 60 according to the separation message. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensing element 51 does not contact the obstacle, the driver can continue to control the flipping of the cargo box 20 by stepping on the accelerator pedal 60 to facilitate the dumping of the cargo.

[0047] In some embodiments, the status information of the sensor 51 includes the distance information between the sensor 51 and the obstacle, and the control device 40 controls the oil circuit control component 52 to connect or disconnect the oil circuit 61 of the accelerator pedal 60 according to the distance information.

[0048] For example, when the distance information between the sensor 51 and the obstacle is greater than the set threshold, the control device 40 controls the oil circuit control component 52 to operate according to the distance information to connect the oil circuit 61 of the accelerator pedal 60. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensor 51 does not contact the obstacle, the driver can continue to control the flipping of the cargo box 20 by stepping on the accelerator pedal 60 to facilitate the dumping of the cargo.

[0049] Or when the distance information between the sensor 51 and the obstacle is less than or equal to the set threshold, the control device 40 controls the oil circuit control component 52 to operate according to the distance information to disconnect the oil circuit 61 of the accelerator pedal 60. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensor 51 contacts the obstacle, the oil circuit 61 of the accelerator pedal 60 will be disconnected. At this time, the cargo box 20 will remain at the current flipping angle, and the driver can no longer control the flipping of the cargo box 20 through the accelerator pedal 60, thereby reducing the risk of the cargo box 20 hitting the obstacle when the cargo box 20 tilts backward relative to the chassis 10, thereby reducing the damage to the cargo box 20.

[0050] In some embodiments, the sensing element 51 includes a sensing bracket 511 and a sensor 512 . The sensing bracket 511 is connected to the cargo box 20 , and the sensor 512 is disposed at one end of the sensing bracket 511 away from the cargo box 20 .

[0051] Therefore, the sensor 512 can be connected to the cargo box 20 through the sensing bracket 511 to reduce the difficulty of setting up the sensor 512, wherein the sensor 512 can include but is not limited to a pressure sensor 512 or an infrared rangefinder, etc. The sensor 512 can be used to sense obstacles by the pressure change between the sensing element 51 and the obstacle or the distance information between the sensing element 51 and the obstacle, etc., which is not limited here.

[0052] At the same time, the sensor 512 is arranged at one end of the sensor bracket 511 away from the cargo box 20, so that the sensor 512 is relatively positioned at the rear on the dump truck 100 with oil circuit control function, thereby better realizing the detection of obstacles.

[0053] In some embodiments, Figure 3 As shown, the sensing bracket 511 includes a connecting rod 5111 and a contact plate 5112 , the connecting rod 5111 is connected between the cargo box 20 and the contact plate 5112 , and the cross-sectional area of ​​the contact plate 5112 is larger than the cross-sectional area of ​​the connecting rod 5111 , and the sensor 512 is disposed on the contact plate 5112 .

[0054] Thus, the area of ​​the location where the sensor 512 is installed can be increased, so that more sensors 512 can be installed, thereby improving the sensing accuracy of the sensor 512 .

[0055] For example, there may be multiple contact plates 5112, which are spaced apart along the extension direction of the connecting rod 5111, and there may be multiple sensors 512 on each contact plate 5112, which may be arranged in multiple rows and columns. The sensing accuracy of the sensors 512 can be improved by increasing the number of sensors 512.

[0056] In some embodiments, Figure 4 As shown, the sensing bracket 511 also includes a mounting bracket 5113 , which is detachably connected to the cargo box 20 , and the connecting rod 5111 is connected between the mounting bracket 5113 and the contact plate 5112 .

[0057] Therefore, by setting the mounting bracket 5113 to be detachably connected to the cargo box 20, the sensing component 51 can be detachably connected to the cargo box 20, so as to facilitate the optional installation of the sensing component 51 according to actual usage requirements, wherein the connection method between the mounting bracket 5113 and the cargo box 20 can be bolt connection, clip connection or plug-in connection, etc., which is not limited here.

[0058] In some embodiments, the connecting rod 5111 is rotatably connected to the mounting bracket 5113.

[0059] Thus, the rotation of the connecting rod 5111 relative to the mounting bracket 5113 can be controlled to adjust the relative position of the sensing element 51 and the cargo box 20, thereby ensuring that the sensing element 51 can better sense obstacles.

[0060] For example, the connecting rod 5111 may be a columnar structure, and both ends of the connecting rod 5111 are respectively passed through a mounting bracket 5113, so that the connecting rod 5111 can rotate relative to the mounting bracket 5113 with itself as a rotating axis.

[0061] Alternatively, a bearing (not shown in the figure) may be provided at the connection between the connecting rod 5111 and the mounting bracket 5113, the connecting rod 5111 is passed through the mounting bracket 5113, the bearing is installed on the mounting bracket 5113, and the bearing is sleeved on the connecting rod 5111, so that the connecting rod 5111 can rotate with the mounting bracket 5113 through the bearing.

[0062] In some embodiments, the mounting bracket 5113 is connected to the cargo box 20 by bolts.

[0063] Therefore, by setting the mounting bracket 5113 and connecting it to the cargo box 20 through bolts, the sensing component 51 and the cargo box 20 can be detachably connected, so that the sensing component 51 can be installed conveniently according to actual usage requirements. At the same time, the bolt connection method is relatively simple and has a higher structural strength.

[0064] In some embodiments, the sensor 51 has a stowed state and an extended state. In the stowed state, the sensor 51 is stowed in the cargo box 20. In the extended state, at least a portion of the sensor 51 extends out of the cargo box 20 in the length direction of the dump truck 100 with oil circuit control function.

[0065] Therefore, when there is no need to flip the cargo box 20, the sensing component 51 can be controlled to be in a stored state to reduce damage to the sensing component 51 and to avoid misoperation of the sensing component 51. When it is necessary to flip the cargo box 20, the sensing component 51 can be controlled to be in an extended state, thereby facilitating the use of the sensing component 51 to detect obstacles.

[0066] In some embodiments, the cargo box 20 may be provided with a storage space (not shown in the figure) so that the sensor 51 can be stored in the storage space, thereby facilitating the use of the storage space of the cargo box 20 to realize the storage of the sensor 51, thereby reducing the space occupied by the sensor 51 when in the storage state.

[0067] In some embodiments, the sensing element 51 is rotatably mounted on the cargo box 20 .

[0068] Therefore, the sensing member 51 can be rotated relative to the cargo box 20 to switch between the storage state and the extended state of the sensing member 51, thereby reducing the difficulty of switching between the storage state and the extended state of the sensing member 51.

[0069] It should be understood that in the implementation in which the sensing member 51 is rotatably installed on the cargo box 20, when the sensing member 51 is in the storage state, it means that the sensing member 51 does not protrude from the cargo box 20 in the length direction of the dump truck 100 with oil circuit control function.

[0070] The present application also proposes a control method for a dump truck, which is applicable to a dump truck 100 with an oil circuit control function according to any of the above embodiments. Figure 5 As shown, the control method of the dump truck includes:

[0071] S10: Control the cargo box 20 to tip backward relative to the chassis 10;

[0072] S20: Acquiring status information of the sensing element 51;

[0073] S30: The control device 40 controls the oil circuit control component 52 to operate according to the status information.

[0074] For example, the sensing element 51 may be a pressure sensor 512 or an infrared rangefinder, etc. The sensing element 51 may be used to sense obstacles by pressure changes between the sensing element 51 and the obstacle or distance information between the sensing element 51 and the obstacle, etc., which is not limited here.

[0075] It can be understood that the status information of the sensor 51 can be the distance information of the obstacle detected by the sensor 51 or the contact information or separation information of whether the sensor 51 is in contact with the obstacle, etc. The oil circuit control component 52 can be an electronic switching valve, and the action of the oil circuit control component 52 includes connecting the oil circuit 61 of the accelerator pedal 60 or disconnecting the oil circuit 61 of the accelerator pedal 60.

[0076] For example Figure 2 As shown, the electronic switch valve can be used to control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60. It can be understood that when the oil circuit 61 of the accelerator pedal 60 is in a connected state, the accelerator pedal 60 can work normally, and when the oil circuit 61 of the accelerator pedal 60 is in a disconnected state, the accelerator pedal 60 fails.

[0077] The control device 40 may be a controller. When the cargo box 20 tips backward relative to the chassis 10, the control device 40 continuously obtains status information of the sensing component 51, and the control device 40 controls the action of the oil circuit control component 52 according to the status information. In this way, when the cargo box 20 tips backward relative to the chassis 10, the control device 40 may control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60 according to the status information of the sensing component 51, thereby reducing the risk of the cargo box 20 colliding with an obstacle when the cargo box 20 tips backward relative to the chassis 10, thereby reducing damage to the cargo box 20. At the same time, such a control method does not require human observation, which is conducive to reducing the difficulty of operation and improving control accuracy.

[0078] According to the dump truck 100 with oil circuit control function in the embodiment of the present application, its sensor 51 is connected to the cargo box 20, the oil circuit control component 52 is arranged on the oil circuit 61 of the accelerator pedal 60 of the dump truck 100 with oil circuit control function and is used to control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60, and the control device 40 is electrically connected between the sensor 51 and the oil circuit control component 52. In this way, when the cargo box 20 tilts backward relative to the chassis 10, the control device 40 can control the connection or disconnection of the oil circuit 61 of the accelerator pedal 60 according to the status information of the sensor 51, thereby reducing the risk of the cargo box 20 colliding with obstacles when the cargo box 20 tilts backward relative to the chassis 10, thereby reducing damage to the cargo box 20.

[0079] According to the control method of the dump truck in some embodiments of the present application, the status information of the sensing component 51 is obtained, including the touch information when the sensing component 51 contacts the obstacle and the separation information when the sensing component 51 separates from the obstacle, and the control device 40 controls the oil circuit control component 52 to operate according to the status information, including: the control device 40 controls the oil circuit control component 52 to operate according to the touch information to disconnect the oil circuit 61 of the accelerator pedal 60; or the control device 40 controls the oil circuit control component 52 to operate according to the separation information to connect the oil circuit 61 of the accelerator pedal 60.

[0080] It can be understood that when the sensing element 51 contacts an obstacle, a touch message is sent out, and the control device 40 controls the oil circuit control element 52 to operate according to the touch message to disconnect the oil circuit 61 of the accelerator pedal 60. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensing element 51 contacts an obstacle, the oil circuit 61 of the accelerator pedal 60 will be disconnected. At this time, the cargo box 20 will remain at the current flipping angle, and the driver can no longer control the flipping of the cargo box 20 through the accelerator pedal 60, thereby reducing the risk of the cargo box 20 hitting an obstacle when the cargo box 20 tilts backward relative to the chassis 10, thereby reducing damage to the cargo box 20.

[0081] Alternatively, when the sensing element 51 is separated from or not in contact with an obstacle, a separation message is sent out, and the control device 40 controls the oil circuit control element 52 to move the oil circuit 61 connected to the accelerator pedal 60 according to the separation message. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensing element 51 does not contact the obstacle, the driver can continue to control the flipping of the cargo box 20 by stepping on the accelerator pedal 60 to facilitate dumping of the cargo.

[0082] In some embodiments, the status information of the sensor 51 includes the distance information between the sensor 51 and the obstacle, and the control device 40 controls the oil circuit control component 52 to connect or disconnect the oil circuit 61 of the accelerator pedal 60 according to the distance information.

[0083] For example, when the distance information between the sensor 51 and the obstacle is greater than the set threshold, the control device 40 controls the oil circuit control component 52 to operate according to the distance information to connect the oil circuit 61 of the accelerator pedal 60. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensor 51 does not contact the obstacle, the driver can continue to control the flipping of the cargo box 20 by stepping on the accelerator pedal 60 to facilitate the dumping of the cargo.

[0084] Or when the distance information between the sensor 51 and the obstacle is less than or equal to the set threshold, the control device 40 controls the oil circuit control component 52 to operate according to the distance information to disconnect the oil circuit 61 of the accelerator pedal 60. In this way, when the driver controls the flipping angle of the cargo box 20 by stepping on the accelerator pedal 60, if the sensor 51 contacts the obstacle, the oil circuit 61 of the accelerator pedal 60 will be disconnected. At this time, the cargo box 20 will remain at the current flipping angle, and the driver can no longer control the flipping of the cargo box 20 through the accelerator pedal 60, thereby reducing the risk of the cargo box 20 hitting the obstacle when the cargo box 20 tilts backward relative to the chassis 10, thereby reducing the damage to the cargo box 20.

[0085] In some embodiments, when the cargo box of a dump truck is tipping backward relative to the chassis, although it can identify the distance of obstacles and control the oil circuit control component 52 according to the distance to avoid collision with obstacles, in general, obstacles are relative to fixed objects, such as stone piers, electric poles, boxes, etc. If there are moving obstacles such as running children or electric vehicles, the measured distance will continue to change, thereby increasing the difficulty of data processing for the control device 40. Therefore, in a method for controlling a dump truck, the step "the control device 40 controls the oil circuit control component 52 to move according to the status information" also includes:

[0086] Acquire historical traffic flow data, wherein the traffic flow data includes movement trajectories, speeds, and accelerations of pedestrians and vehicles, and vehicles may include electric vehicles, motorcycles, bicycles, and cars.

[0087] Acquire real-time traffic flow data, where the real-time traffic flow data refers to the state of the surrounding environment and obstacles captured in real time by sensors (such as cameras, radars, and LiDAR).

[0088] Construct an initial deep learning model, where the deep learning model can be a recurrent neural network (RNN), a long short-term memory network (LSTM), a convolutional neural network (CNN), etc.

[0089] The historical traffic flow data is used to train the initial deep learning model to obtain the target deep learning model, wherein the historical traffic flow data is firstly subjected to feature extraction to extract traffic flow features in the lost traffic flow data, such as speed, acceleration, direction, distance, etc. Next, the traffic flow features are used to train the initial deep learning model so that the deep learning model can learn the mapping from input features to output (predicted position). In this way, the trained target deep learning model can predict the behavior patterns of obstacles, such as pedestrians’ turning intentions or vehicles’ lane changing intentions.

[0090] Inputting real-time traffic flow data into the target deep learning model to obtain prediction results;

[0091] The prediction results are loaded into the vehicle system, and the prediction results are displayed using the display screen of the vehicle system, wherein the vehicle system represents the multimedia system of the vehicle, and the display screen is the vehicle screen of the vehicle system, so that the operator of the dump truck can observe the prediction results according to the screen, so that the operator can understand the possible obstacle collision in the future. The target deep learning model can be loaded into the vehicle system, so that the vehicle system can be used for calculation, and the prediction results can be displayed using the screen of the vehicle system.

[0092] Specifically, the vehicle system can be connected to the control device 40. In this way, when the vehicle system displays the prediction result, it can also send a signal to the control device 40 so that the control device 40 can respond to the signal and control the oil circuit control component 52. For example, the prediction result predicts that an electric car will pass by in 5 seconds. In this way, the control device 40 will use its own clock to calculate the time after receiving the prediction result signal, and after 5 seconds, it will send an action signal to the oil circuit control component 52 so that the oil circuit control component 52 can execute.

[0093] In one embodiment, in order to enable the target deep learning model training parameters of the current dump truck to help the deep learning models of other dump trucks, so that the deep learning models of all dump trucks in the fleet can continuously learn and improve their accuracy, the following steps may be included:

[0094] Obtain the target deep learning model parameters of the previous day and the target deep learning model parameters of the current day, and compare them to determine the parameter differences;

[0095] The parameter difference is encrypted and sent to the server at a preset first time point, and the model optimization parameter data sent by the server is received at a preset second time point, wherein the model optimization parameter data means that the server aggregates the parameter differences sent to it by multiple dump trucks, generates the latest model optimization parameter data, and sends the model optimization parameter data to all dump trucks at a second time point, so that each dump truck can receive the model optimization parameter data at the second time point and update itself. It should be noted that the model optimization parameter data sent to the dump truck by the server is encrypted data and needs to be decrypted in the dump truck. The encryption and decryption methods can be conventional methods, and the present application does not limit this.

[0096] Use the model to optimize parameter data and update the target deep learning model to obtain the latest target deep learning model.

[0097] In one embodiment, if the server receives parameter difference data sent to it by multiple dump trucks, these parameter difference data are generated by different dump trucks. If there is a conflict in the parameter difference data, it can be handled by the following method:

[0098] Obtain several sets of parameter difference data;

[0099] Assign a weight to each parameter difference data to obtain the weight of each parameter difference data;

[0100] If there is a conflict between two of the several sets of parameter difference data, a weighted average calculation is performed according to the weight of the parameter difference data to obtain the weighted average parameter difference data under the conflicting condition;

[0101] The weighted average parameter difference data and several sets of non-conflicting parameter difference data are combined into model optimization parameter data, which are encrypted and sent to the dump truck.
