DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] In order to facilitate the understanding of this embodiment, the application scenarios and design concepts of the embodiments of the present application are briefly introduced below.

[0028] At present, when the battery-swapping dump truck needs to lift the cargo box during the battery-swapping process, the cargo box is lifted by manually operating the gas-controlled lifting handle. The cargo box is lifted to a certain angle based on observation and experience, and then the battery swap is started. After the battery swap is completed, the cargo box is lowered back to its original position by manually operating the gas-controlled lifting handle. In this process, there are safety hazards caused by operational errors, and the battery swap speed is affected.

[0029] Based on this, an embodiment of the present application provides an automatic control method, device and system for a battery swap vehicle. The method is applied to an automatic control system of a battery swap vehicle. The system includes: a vehicle, a battery swap station and a flip-in-place detection terminal. The flip-in-place detection terminal is arranged on the vehicle; the battery swap station and the flip-in-place detection terminal are respectively communicatively connected to the vehicle's controller 5.

[0030] Example 1 The present application provides an automatic control method for a battery-swapping vehicle, which is applied to a controller 5 in a battery-swapping vehicle. Figure 1 As shown, the method includes: S110, after the vehicle drives to the designated battery swapping location, in response to the battery swapping instruction sent by the battery swapping station, the vehicle is controlled to operate in the battery swapping mode.

[0031] S120, controlling the operation of the power take-off and conducting the lifting air path in the air path module to lift the cargo box of the vehicle.

[0032] S130, determining whether a lifting-in-place signal sent by a flip-in-place detection terminal is received.

[0033] If so, execute step S140.

[0034] S140, controlling the lifting air path to be blocked so that the cargo box is suspended.

[0035] S150, controlling the vehicle's entire high voltage power supply to be cut off and controlling the battery to be unlocked.

[0036] S160, sending a battery replacement request to the battery replacement station.

[0037] The automatic control method of the battery swap vehicle provided in the present application is that after the vehicle drives to the designated battery swap position, it enters the battery swap mode in response to the battery swap command sent by the battery swap station, opens the lifting gas path in the gas path module to lift the cargo box, and blocks the lifting gas path to make the cargo box hover after receiving the lifting in place signal, and performs battery swapping in the safe condition of cutting off the high voltage of the whole vehicle and unlocking the battery. In this way, it is judged whether the battery swap can be performed through the lifting in place detection, and the high voltage of the whole vehicle is automatically cut off to provide a safe battery swap environment when the battery swap can be performed. The degree of automation is high, which can reduce the intensity of manual labor, reduce the safety hazards caused by manual lifting, and improve the efficiency of battery swapping.

[0038] It can be understood that the "designated battery swapping position" in step S110 can be understood as a parking space, queuing area, etc. in the battery swapping station or the designated battery swapping area. The designated battery swapping position is a pre-planned position suitable for the vehicle model. That is, there can be multiple "designated battery swapping positions" in a battery swapping station, such as position A, position B, position C...position G. These "designated battery swapping positions" can correspond to the same vehicle model, or can correspond to multiple vehicle models according to actual needs. This is only an example and is not limited.

[0039] A detection device should be provided in the battery swap station to monitor whether there are vehicles entering each "designated battery swap position". When a vehicle is detected to enter a "designated battery swap position" (for example, position C), a battery swap command is sent to the vehicle in the "designated battery swap position". That is, a battery swap command is sent to the vehicle in position C (marked as vehicle C). At this time, the controller 5 in vehicle C switches vehicle C to the battery swap mode.

[0040] Step S120 controls the operation of the power take-off (i.e., switches the control switch of the power take-off to the "engaged" position to start the power take-off). At this time, the power take-off will obtain power from the engine and generate high-pressure oil through the hydraulic pump, and open the lifting air path in the air path module to allow the high-pressure oil to enter the lifting cylinder 3. With the entry of the high-pressure oil, the lifting power is provided to the lifting cylinder 3, thereby pushing the cargo box to gradually rise.

[0041] Combination Figure 8 As shown, a flipping detection terminal is installed on the rear side of the vehicle, and the flipping detection terminal is used to detect whether the flipping of the cargo box reaches the specified position. It can be understood that the flipping detection terminal can adopt a proximity switch, a travel switch or a photoelectric sensor. In this embodiment, there are two specified positions, one is a lifting specified position, and the other is a lowering specified position. Preferably, additional specified positions can be provided for different battery swapping scenarios, so that after the battery swapping scenario is determined, the target lifting specified position and the target lowering specified position corresponding to the battery swapping scenario can be retrieved, and the vehicle control steps such as steps S130-S160 can be performed based on the retrieved target lifting specified position and target lowering specified position.

[0042] In step S130, the flipping detection terminal monitors the lifting position of the cargo box in real time and compares it with the lifting limit position to determine whether the lifting limit position has been reached. If so, the flipping detection terminal generates and sends a lifting signal to the vehicle controller 5. If not, the monitoring continues.

[0043] After receiving the lifting signal (that is, the cargo box has reached the expected lifting limit position), step S140 blocks the lifting air circuit, which will cause the high-pressure oil to remain in the lifting cylinder 3, so that the cargo box is suspended in the current position. Then, step S150 switches the high-voltage power cut-off switch to the "off" position to cut off the high-voltage power supply of the entire vehicle, and switches the battery unlocking switch to the "unlocked" position so that the battery can be removed or replaced. At this point, it is in a safe environment for battery replacement. Subsequently, step S160 sends a battery replacement request to the battery swap station to convey to the battery swap station the information that it is currently in a safe battery swap environment and that the battery can be replaced.

[0044] In combination with the first aspect, after step S160, in combination with Figure 2 Also shown are: S210, after the battery is replaced, in response to the battery replacement completion signal from the battery replacement station, the battery is controlled to be locked and connected to the high voltage power of the entire vehicle.

[0045] S220, determining whether the high voltage power of the entire vehicle is successfully connected.

[0046] If so, execute step S230.

[0047] S230, opening the descending air path in the air path module to lower the cargo box.

[0048] S240, determining whether a falling in place signal sent by the flipping in place detection terminal is received.

[0049] If so, execute step S250.

[0050] S250, confirm that the cargo box is lowered into place and exit the battery replacement mode.

[0051] After the battery is replaced manually or through automated equipment, the battery swap station sends a battery replacement completion signal to the vehicle's controller 5. At this time, the controller 5 locks the battery to fix the battery in the battery compartment to prevent unauthorized movement or replacement, and connects the high voltage power of the entire vehicle.

[0052] Afterwards, monitor whether the high voltage power of the whole vehicle is successfully connected to ensure that the vehicle can operate safely and reliably. Specifically, as an implementable method, measure between the positive and negative poles of the battery, or at a test point in the high voltage power system of the vehicle. Specifically, connect the positive pole (red probe) of the voltmeter to the positive pole of the battery or the positive test point of the high voltage power system, and connect the negative pole (black probe) to the negative pole of the battery or the negative test point of the high voltage power system. Read the voltmeter reading. If the reading is consistent with the nominal voltage of the vehicle battery, it means that the high voltage power has been successfully connected.

[0053] As another feasible method, use the vehicle diagnostic tool OBD to connect to the vehicle's diagnostic interface, and read the vehicle's fault code and system status. If there is no fault code related to the high-voltage electrical system and the system status is normal, it means that the high-voltage power has been successfully connected.

[0054] As another feasible method, try to start the vehicle and check whether the various functions of the vehicle are working properly, such as the steering oil pump, air pump, etc. If these functions can work properly, it means that the high voltage has been successfully connected.

[0055] The above methods can be selected according to usage requirements. In this embodiment, in order to improve the safety of battery replacement, OBD diagnosis method is used for judgment.

[0056] After the high-voltage electrical connection of the entire vehicle is successful, the descent control switch is switched to the "descend" position to generate a descent control signal and open the descending air path in the air path module. At this time, the high-pressure oil in the lifting cylinder 3 flows back to the oil storage tank 2 to lower the cargo box.

[0057] Then, the flipping in place detection terminal 4 monitors the lowering position of the cargo box in real time and compares it with the lowering limit position to determine whether the lowering limit position has been reached. If so, the flipping in place detection terminal generates and sends a lowering in place signal to the vehicle controller 5. If not, the monitoring continues.

[0058] The controller 5 exits the battery swap mode after receiving the signal of descending to the designated position, which indicates that the lifting, battery swapping and descending operations required for the battery swap have all been completed.

[0059] In combination with the first aspect, after step S110, the method further includes: S121, obtaining the current operation mode.

[0060] S122, determine whether the current operating mode is the battery replacement mode.

[0061] If not, execute step S123. If yes, execute steps S130-S160.

[0062] S123, determine that the battery replacement mode switch fails, and control the vehicle to stop running.

[0063] After the controller 5 switches the vehicle's operating mode to the battery swap mode, the mode after the switching operation is checked to determine whether the switching is successful. If the mode switching fails, the vehicle should be stopped in time to avoid safety hazards caused by battery swapping under abnormal vehicle conditions. If the mode switching is successful, the subsequent battery swap operation can be continued.

[0064] In combination with the first aspect, after step S130, the method further includes: If not, execute step S141.

[0065] S141, continuously conduct the lifting air circuit to lift the cargo box of the vehicle until a lifting-in-place signal is received.

[0066] During the lifting process, the flip-in-place detection terminal monitors the lifting position of the cargo box in real time until it reaches the lifting limit position and generates and sends a lifting in-place signal to the controller 5. The controller 5 stops conducting the lifting air path only after receiving the lifting in-place signal.

[0067] After step S220, the method further includes: If not, execute steps S231-S232.

[0068] S231, repeatedly connect the high voltage power of the whole vehicle and accumulate the number of connections.

[0069] S232: If the number of connections reaches a preset number threshold, a fault signal is generated and returned.

[0070] After the battery is replaced, the vehicle is connected to high voltage power while in hovering state and the number of connections is accumulated. If the number of repeated connections reaches the threshold and the connection is still not successful, a fault signal is returned to remind the operator to perform vehicle maintenance.

[0071] In combination with the first aspect, after step S240, the method further includes: If not, execute step S250.

[0072] S250, continuously conduct the descending gas path in the gas path module until receiving a descending position signal sent by the flipping position detection terminal, and blocking the gas path module.

[0073] During the descent process, the descent position of the cargo box is continuously monitored until the descent limit position is received, and the flip-in-place detection terminal 4 generates and sends a descent in-place signal to the controller 5. At this time, the controller 5 blocks the gas path module after receiving the descent in-place signal to stop driving the cargo box to descend. The descent limit position is usually the initial position of the cargo box.

[0074] Example 2 In a second aspect, the present application provides an automatic control method for a battery swapping vehicle, which is applied to a battery swapping station. Figure 3 , the method comprising: S310, determine whether there is a vehicle to be replaced at the designated battery replacement location.

[0075] If so, execute S320.

[0076] S320, sending a battery replacement instruction to the vehicle to be replaced.

[0077] S330, receiving a battery replacement request sent by the vehicle to be replaced.

[0078] S340: After the battery replacement is completed, a battery replacement completion signal is sent to the vehicle to be replaced.

[0079] In this embodiment, it is first determined whether there is a vehicle to be replaced that has entered the designated battery swapping position, and if there is a vehicle to be replaced that has entered, a battery swapping instruction is sent to the vehicle to be replaced, and the battery swapping vehicle is waited for to prepare for the battery swap. After receiving the battery swapping request sent by the vehicle to be replaced, it indicates that the vehicle to be replaced is ready. At this time, manual or automatic battery swapping can be performed according to the actual situation, and after the battery swapping is completed, a battery replacement completion signal is sent to the vehicle to be replaced, so as to prompt the vehicle to adjust its status and leave the designated battery swapping position as soon as possible.

[0080] Example 3 In a third aspect, the present application also provides an automatic control method for a battery-swapping vehicle, which is applied to the flip-in-place detection terminal 4. Figure 4 As shown, the method includes: S410, acquiring position detection data.

[0081] S420, determining a current flipping position according to a comparison relationship between the position detection data and a plurality of preset thresholds.

[0082] S430: If the current flipping position reaches the preset lifting limit position, a lifting position reaching signal is sent to the controller.

[0083] S440: If the current flipping position drops to the preset drop limit position, a drop position arrival signal is sent to the controller.

[0084] During the operation of the flipping position detection terminal 4, position detection data is acquired in real time, and the current flipping position is determined based on the acquired position detection data. When the current flipping position reaches the lifting limit position, a lifting position signal is generated and sent to the vehicle controller 5. When the current flipping position reaches the lowering limit position, a lowering position signal is generated and sent to the vehicle controller 5.

[0085] Example 4 In a fourth aspect, the present application provides an automatic control device for a battery-swapping vehicle, which is applied to a controller 5 of a battery-swapping vehicle, and is combined with Figure 5 As shown, the device includes: a response module 10, a lifting conduction module 20, a lifting in place judgment module 30, a hovering module 40, a control module 50 and a battery replacement request sending module 60.

[0086] The response module 10 is used to control the vehicle to operate in a battery swap mode in response to a battery swap instruction sent by the battery swap station after the vehicle travels to a designated battery swap location.

[0087] The lifting conduction module 20 is used to control the operation of the power take-off and conduct the lifting air circuit in the air circuit module to lift the cargo box of the vehicle.

[0088] The lifting-in-place judgment module 30 is used to judge whether a lifting-in-place signal sent by the flipping-in-place detection terminal is received.

[0089] The hovering module 40 is used to control the blocking of the lifting air path when receiving a lifting-in-place signal, so that the cargo box is hovered.

[0090] The control module 50 is used to control the high voltage power cut-off of the vehicle and control the battery unlocking.

[0091] The battery swap request sending module 60 is used to send a battery swap request to a battery swap station.
