[0002] A commercial refrigerated truck is a vehicle designed for transporting goods that need to be kept at a specific temperature. These vehicles are widely used in the food, pharmaceutical, chemical and other industries to ensure that products remain fresh or preserved as required during transportation. In the modification of existing commercial refrigerated trucks, the control of the refrigeration machine is usually achieved by adding a physical button screen or LCD screen to the cab, but such modification will affect the driver's field of vision.

[0029] Figure 1 It is a schematic diagram of an exemplary system architecture shown in an exemplary embodiment of the present application.

[0030] Reference Figure 1As shown, the system architecture may include a vehicle control terminal 110 and a computer device 120. The computer device 120 receives the control operation information of the vehicle control terminal 110, determines the cooling machine control type information according to the control operation information, generates a cooling machine control request based on the cooling machine control type information, and sends the cooling machine control request to the vehicle control unit.

If the cooling machine control operation is normal, the cooling machine control operation normal information is fed back to the vehicle control terminal, and the cooling machine control operation normal information is displayed on the vehicle control terminal. The above-mentioned computer device 120 may be at least one of a microcomputer, an embedded computer, a network computer, an industrial computer, etc.; the vehicle control terminal 110 is the central control screen of the vehicle.

[0031] Illustratively, the computer device 120 receives control operation information from the vehicle control terminal 110, determines the cooling machine control type information according to the control operation information, generates a cooling machine control request based on the cooling machine control type information, and sends the cooling machine control request to the vehicle control unit.

If the cooling machine control operation is normal, the normal cooling machine control operation information is fed back to the vehicle control terminal, and the normal cooling machine control operation information is displayed on the vehicle control terminal. The present application saves instrument panel space by integrating the cooling machine control function on the existing vehicle control terminal, avoids affecting the driver's field of vision and reduces the driver's operation points, avoids frequent switching of attention during driving, and improves driving safety. The control scheme uses the existing vehicle control terminal for software development, avoids additional hardware investment, and processes the cooling machine control request through the vehicle control unit to achieve intelligent control of the cooling machine high-voltage input, thereby improving the safety of cooling machine control.

[0032] Figure 2 is a flowchart of a chiller control method shown in an exemplary embodiment of the present application. The chiller control method can be Figure 1 The implementation environment may be implemented in other implementation environments, and the above implementation environments are not specifically limited here. Figure 2 As shown, the flowchart of the chiller control method includes at least steps S210 to S240, which are described in detail as follows:

[0033] In step S210, control operation information of the vehicle control terminal is received, and cooling machine control type information is determined according to the control operation information.

[0034] In one embodiment of the present application, the control operation information of the vehicle control terminal is received by the vehicle user's touch screen operation information through the vehicle's central control screen, and the type of control information of the cold machine that the current user needs to control is determined through the point information and control information of the touch screen operation information. For example, the cold machine control interface is designed according to the cold machine control method at the vehicle control terminal, and is packaged as a tool software and installed in the vehicle's central control. When the user needs to control the cold machine, the control interface is opened, which is provided with virtual control buttons such as cold machine power on, cold machine power off, and cold machine forced shutdown. The vehicle user selects the control according to the current vehicle's cold machine control requirements.

[0035] In step S220, a cooling machine control request is generated based on the cooling machine control type information, and the cooling machine control request is sent to the vehicle control unit.

[0036] In one embodiment of the present application, the above-mentioned cooling machine control type information includes cooling machine power-on control and cooling machine power-off control.

[0037] In one embodiment of the present application, if the refrigerator control type information is refrigerator power-on control, a power-on request is generated; if the refrigerator control type information is refrigerator power-off control, a power-off request is generated.

[0038] In one embodiment of the present application, it should be noted that the specific control operation name of the above-mentioned cold machine power-on control may be reflected in different names such as turning on the cold machine, starting the cold machine, powering on the cold machine, starting refrigeration, etc. Similarly, the specific control operation name of the above-mentioned cold machine power-off control may be reflected in different names such as shutting down the cold machine, ending refrigeration, and powering off the cold machine.

[0039] In step S230 , the vehicle control unit controls the target controller to perform a cooling machine control operation according to the cooling machine control request.

[0040] In one embodiment of the present application, if the cold machine control request is a top-mounted power-on request. The cold machine controller is called to perform a cold machine operation status check to obtain the cold machine operation status. The cold machine operation status check includes power connection self-check, sensor self-check, temperature self-check, and fault code self-check. The cold machine operation status includes normal high voltage on the cold machine and abnormal high voltage on the cold machine; if the cold machine operation status is normal high voltage on the cold machine, the top-mounted power-on request is sent to the vehicle control unit; if the cold machine operation status is abnormal high voltage on the cold machine, a cold machine abnormal text message is generated according to the abnormal high voltage on the cold machine, and the cold machine abnormal text message is displayed on the vehicle control terminal. The vehicle control unit responds to the top-mounted power-on request and controls the closing of the top-mounted relay; if the vehicle control unit feedbacks that the top-mounted relay is closed successfully within the preset power-on time, it is determined that the cold machine control operation is normal; if the vehicle control unit feedbacks that the top-mounted relay fails to close or does not provide feedback within the preset power-on time, it is determined that the cold machine control operation is abnormal.

[0041] Among them, the high pressure on the cold machine is normal means that in the cold machine operation status check, each self-check item is checked without abnormality. If any self-check item is abnormal, the cold machine operation status is determined to be abnormal high pressure on the cold machine. The above cold machine abnormal text information is specifically reflected in the detailed fault display on the vehicle control terminal through the controller fault code corresponding to the self-check item.

[0042] In one embodiment of the present application, if the cold machine control request is a top-mounted power-off request, the cold machine controller is called to disconnect the cold machine relay; if the cold machine relay is successfully disconnected, the top-mounted power-off request is sent to the vehicle control unit. The vehicle control unit uses the receiving time of the control operation information as the timing starting point for timing; if the vehicle control unit receives the top-mounted power-off request within the preset power-off timing duration, the top-mounted relay is controlled to be disconnected at the moment of receiving the top-mounted power-off request; if the vehicle control unit does not receive the top-mounted power-off request within the preset power-off timing duration, the top-mounted relay is controlled to be disconnected when the timing reaches the preset power-off timing duration. If the vehicle control unit controls the disconnection of the top-mounted relay normally, it is determined that the cold machine control operation is normal; if the vehicle control unit fails to control the disconnection of the top-mounted relay or there is no feedback information, it is determined that the cold machine control operation is abnormal.

[0043] In step S240, if the cooling machine control operation is normal, the cooling machine control operation normal information is fed back to the vehicle control terminal, and the cooling machine control operation normal information is displayed on the vehicle control terminal.

[0044] In one embodiment of the present application, if the cooling machine control operation is abnormal, the abnormal information is fed back to the vehicle control terminal, and the abnormal information is displayed on the vehicle control terminal.

[0045] During the use of the cold machine, there are some situations that may cause the cold machine to power off abnormally, such as the emergency stop switch is activated, the main relay of the upper power supply is abnormally disconnected, the main relay of the power distribution unit is abnormally disconnected, the battery control system requests high voltage, the main relay of the motor is abnormally disconnected, the chassis power is turned off, the vehicle's third-level fault or the cold machine controller communication timeout.

[0046] In other embodiments of the present application, if there is any abnormal power-off condition including chassis power off, vehicle level 3 fault or cooling machine controller communication timeout, the vehicle control unit calls the cooling machine controller to disconnect the cooling machine relay, and starts timing with the time of receiving the control operation information; when the vehicle control unit receives an upper-mounted power-off request within the preset power-off timing duration, the upper-mounted relay is controlled to be disconnected at the moment of receiving the upper-mounted power-off request; when the vehicle control unit does not receive an upper-mounted power-off request within the preset power-off timing duration, the upper-mounted relay is controlled to be disconnected when the timing reaches the preset power-off timing duration.

[0047] In other embodiments of the present application, if there is any abnormal power-off condition including the emergency stop switch being activated, the upper power main relay being abnormally disconnected, the power distribution unit main relay being abnormally disconnected, the battery control system requesting high voltage to be disconnected, or the motor main relay being abnormally disconnected, the vehicle control unit controls the disconnection of the entire vehicle high voltage and the cold machine controller is forced to power off.

[0048] Please refer to Figure 3 As shown, Figure 3 is a specific schematic diagram of a refrigerator power-on control logic shown in an exemplary embodiment of the present application, such as Figure 3 As shown in the figure, after power-on starts, the chassis is in the ON or Ready state (at this time, the cold machine controller, VCU, GW, and central control screen are in the awake state), otherwise the power-on fails; if it is in the ON or Ready state, determine whether the vehicle has no faults. If so, click the central control screen button to initiate a cold machine startup request and send the "upper body start-stop command-request to start" to the cold machine controller. The cold machine controller determines the current cold machine state and whether high voltage is allowed. If allowed, it sends the "upper body high voltage request command-upper body power-on request" to the VCU; if the cold machine cannot be started normally, a fault message needs to be sent. The fault code is sent to the CAN bus and displayed on the central control screen; after the VCU receives the "upper load high voltage request instruction-upper load power-on request" signal, it sends the upper load relay closing instruction to the all-in-one controller; the all-in-one controller controls the closing of the upper load relay and feeds back the closing status to the VCU. If within a certain period of time, the VCU does not feed back to the refrigerator that the upper load power is successful, the refrigerator controller needs to report a timeout and report a "VCU refuses to supply high voltage fault"; if the VCU sends "upper load high voltage status-there is high voltage" to the refrigerator controller normally, the refrigerator sends the working status as startup, and the startup is completed.

[0049] Please refer to Figure 4 As shown, Figure 4 is a specific schematic diagram of a cooling machine power-off control logic shown in an exemplary embodiment of the present application, such as Figure 4 As shown, after the central control panel turns off the upper power supply, it sends the "cold machine start and stop command-request to shut down" to the cold machine controller, and the VCU monitors and calculates the timeout time. The timeout time starts from pressing the button on the large screen; the cold machine controller controls the cold machine to stop working, disconnects the internal high-voltage relay, and then sends the "upper-mounted high-voltage request command-upper-mounted power-off request" to the VCU; the VCU receives the "upper-mounted high-voltage request command-upper-mounted power-off request" or the VCU does not receive the "upper-mounted high-voltage request command-upper-mounted power-off request" within the specified time after receiving the "cold machine start and stop command-request to shut down" from the large screen, then the VCU controls to disconnect the upper-mounted high-voltage relay and force the power off. After the upper-mounted high-voltage relay is disconnected, the VCU feedbacks "upper-mounted high-voltage status-no high voltage".

[0050] The present application uses a VCU to control the opening and closing of the upper-mounted high-voltage relay, and controls the high-voltage input of the refrigerator from the all-in-one distribution box, so that when the refrigerator of the refrigerated truck is not working, the refrigerator controller does not need to be continuously in a high-voltage state, and effectively isolates the danger of high-voltage leakage and electric shock from the distribution head, ensuring the absolute isolation of the refrigerator system from the high voltage when not working. Compared with the traditional method of continuously supplying high voltage to the refrigerator, the high-voltage control strategy of the present application is safer.

[0051] The present invention provides a cooling machine control method, device, electronic device and storage medium, which receive control operation information from a vehicle control terminal, determine cooling machine control type information according to the control operation information, generate a cooling machine control request based on the cooling machine control type information, and send the cooling machine control request to a vehicle control unit. The vehicle control unit controls a target controller to perform cooling machine control operation according to the cooling machine control request. If the cooling machine control operation is normal, the normal cooling machine control operation information is fed back to the vehicle control terminal, and the normal cooling machine control operation information is displayed at the vehicle control terminal. The present application integrates the cooling machine control function on the existing vehicle control terminal, thereby saving instrument panel space, avoiding affecting the driver's field of vision and reducing the driver's operation points, avoiding frequent switching of attention during driving, and improving driving safety. The control scheme uses the existing vehicle control terminal for software development, avoiding additional hardware investment, and processes the cooling machine control request through the vehicle control unit to achieve intelligent control of the high-voltage input of the cooling machine, thereby improving the safety of cooling machine control.
