[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] Exemplary vehicle body control device

[0025] Figure 1 The diagram shown is a schematic representation of a vehicle body control device according to an embodiment of this application. This application provides a vehicle body control device applied to a concrete mixer truck. In one embodiment, as... Figure 1 As shown, the vehicle body control device includes an intelligent entry module 100, a vehicle start module 101, a vehicle function control module 102, a gateway module 103, an engine remote start / stop control module 104, and a mixing drum control data communication module 105.

[0026] The intelligent entry module 100 is used to perform keyless entry, and the vehicle start module 101 is used to perform one-button start. Specifically, the intelligent entry module 100 and the vehicle start module 101 are connected to a low-frequency antenna, a door handle switch, and a one-button start switch. The low-frequency antenna is used to communicate with the remote key. The vehicle function control module 102 is used to perform lighting control, wiper control, horn control, and door and window control functions. The gateway module 103 is used to perform gateway communication functions. The engine remote start / stop control module 104 is used to perform engine remote start / stop functions, and the pump truck remote controller communicates remotely with the engine remote start / stop control module 104. The mixing drum control data communication module 105 is used to perform the communication function of mixing drum control signals.

[0027] In this embodiment, multiple functions are integrated into one, and the integrated vehicle control device can perform various functions: keyless entry, one-button start, lighting control, windshield wiper control, horn control, door and window control, gateway communication, remote engine start / stop, and communication of mixing drum control signals. The diverse and integrated functions of the vehicle control device in this embodiment improve the convenience and ease of use of the concrete mixer truck.

[0028] Furthermore, this vehicle body control device can also be applied to concrete pump trucks. When installed on a concrete pump truck, it can simultaneously control the remote start and stop of the engines of both the concrete pump truck and the concrete mixer truck. When installed on a concrete mixer truck, it can also simultaneously control the remote start and stop of the engines of both the concrete pump truck and the concrete mixer truck.

[0029] Figure 2 The diagram shown is a system structure schematic of a vehicle body control device according to another embodiment of this application. In one embodiment, as... Figure 2 As shown, the vehicle body control device also includes a first microcontroller 106 and a second microcontroller 107. The intelligent entry module 100, the vehicle start module 101, and the vehicle function control module 102 are integrated on the first microcontroller 106, while the gateway module 103, the engine remote start-stop control module 104, and the mixing drum control data communication module 105 are integrated on the second microcontroller 107.

[0030] In this embodiment, a first microcontroller 106 integrates an intelligent entry module 100, a vehicle start module 101, and a vehicle function control module 102, and provides computing power for these modules. A second microcontroller 107 integrates a gateway module 103, an engine remote start-stop control module 104, and a mixing drum control data communication module 105, and provides computing power for these modules as well.

[0031] In one embodiment, such as Figure 2 As shown, the gateway module 103 includes a LIN bus connection unit and a CAN bus connection unit. The LIN bus connection unit is used to connect to the LIN bus to realize LIN bus communication, and the CAN bus connection unit is used to connect to the CAN bus to realize CAN bus communication.

[0032] Figure 3 The diagram shown is a system structure schematic of a stirring tank control data communication module according to another embodiment of this application. In one embodiment, as... Figure 3As shown, the mixing drum control data communication module 105 includes a handle signal receiving unit 1051 and a central control screen signal receiving unit 1052. The handle signal receiving unit 1051 receives a first mixing drum control signal from the mixing drum control handle of the concrete mixer truck, and the central control screen signal receiving unit 1052 receives a second mixing drum control signal from the central control screen of the concrete mixer truck. When the operator of the concrete mixer truck operates the mixing drum, they can send a control signal through the mixing drum control handle, which serves as the first mixing drum control signal; the operator can also send a control signal through the central control screen, which serves as the second mixing drum control signal.

[0033] In one embodiment, such as Figure 3 As shown, the stirring drum control data communication module 105 also includes a control signal sending unit 1053, which is used to send the first stirring drum control signal or the second stirring drum control signal to the stirring drum drive system. After the stirring drum drive system obtains the first stirring drum control signal or the second stirring drum control signal, it can drive the stirring drum to rotate, realizing the forward and reverse rotation, acceleration and deceleration, and multi-position control of the stirring drum.

[0034] In one embodiment, such as Figure 3 As shown, the stirring drum control data communication module 105 also includes a data redundancy unit 1054, which is communicatively connected to the handle signal receiving unit 1051, the central control screen signal receiving unit 1052, and the control signal sending unit 1053, respectively.

[0035] In one embodiment, the data redundancy unit 1054 is configured as follows:

[0036] Receive and buffer the first stirring tank control signal and / or the second stirring tank control signal; and

[0037] If both the first stirring tank control signal and the second stirring tank control signal are received simultaneously, and the first stirring tank control signal and the second stirring tank control signal are the same, then the first stirring tank control signal or the second stirring tank control signal is stored, and the second stirring tank control signal or the first stirring tank control signal is sent to the control signal sending unit.

[0038] In one embodiment, the data redundancy unit 1054 is configured as follows:

[0039] If both the first stirring tank control signal and the second stirring tank control signal are received simultaneously, and the first stirring tank control signal and the second stirring tank control signal are different, then the first stirring tank control signal and the second stirring tank control signal are stored, and a redundant prompt signal is generated; if a confirmation signal is obtained, then the first stirring tank control signal or the second stirring tank control signal corresponding to the confirmation signal is sent to the control signal sending unit.

[0040] In one embodiment, the data redundancy unit 1054 is configured as follows:

[0041] If the first stirring drum control signal and the second stirring drum control signal are not received simultaneously, a stirring drum stop signal is generated and sent to the control signal sending unit; if an acknowledgment signal is obtained, the first stirring drum control signal or the second stirring drum control signal corresponding to the acknowledgment signal is sent to the control signal sending unit.

[0042] In this embodiment, when both a first stirring drum control signal and a second stirring drum control signal are received simultaneously, and the first and second stirring drum control signals are identical, this corresponds to the operator simultaneously performing operations on both the stirring drum control handle and the central control screen. This indicates that the stirring drum drive system can operate based on either the first or second stirring drum control signal. Therefore, one of the first and second stirring drum control signals is stored, and the other, which is not stored, is sent to the control signal sending unit.

[0043] When both the first and second stirring drum control signals are received simultaneously, and these signals differ, this indicates that the operator has simultaneously executed operations on both the stirring drum control handle and the central control screen, resulting in different actions. In this case, a redundancy prompt signal is generated. This signal is sent to the central control screen to alert the operator. Based on the redundancy prompt signal, the operator decides whether to use the first or second stirring drum control signal. After making a decision, the operator sends a confirmation signal through the central control screen, which corresponds to either the first or second stirring drum control signal. Upon receiving the confirmation signal, the data redundancy unit sends the corresponding control signal to the control signal sending unit.

[0044] When the first and second mixing drum control signals are not received simultaneously, it indicates that the operator has issued different control signals. In this case, a mixing drum stop signal is generated to stop the mixing drum and prevent erroneous operation. After stopping, the operator needs to decide whether to use the first or second mixing drum control signal. Once decided, a confirmation signal is sent through the central control screen. This confirmation signal corresponds to either the first or second mixing drum control signal. Upon receiving the confirmation signal, the data redundancy unit sends the corresponding control signal to the control signal sending unit.

[0045] Figure 4 The diagram shown is a system structure schematic of a vehicle body control device according to another embodiment of this application. In one embodiment, as... Figure 4As shown, the vehicle body control device also includes a power consumption adjustment module 108, which is configured to acquire the current data volume and adjust the real-time power of the vehicle body control device according to the current data volume. This embodiment can adjust the power consumed by the vehicle body control device based on the current data volume, thereby achieving better energy utilization.

[0046] Figure 5 The diagram shown is a system structure schematic of a vehicle body control device according to another embodiment of this application. In one embodiment, as... Figure 5 As shown, the vehicle body control device is connected to a power module 110, wherein the power consumption adjustment module 108 includes a data volume statistics unit 1081 and a power matching unit 1082.

[0047] The data volume statistics unit 1081 is communicatively connected to the intelligent entry module 100, the vehicle start module 101, the vehicle function control module 102, the gateway module 103, the engine remote start-stop control module 104, and the mixing drum control data communication module 105, respectively. The data volume statistics unit 1081 is configured to acquire the total communication data volume of one or more of the following modules: intelligent entry module, vehicle start module, vehicle function control module, gateway module, engine remote start-stop control module, and mixing drum control data communication module.

[0048] The power matching unit 1082 is communicatively connected to the data volume statistics unit 1081 and the power module 110 respectively. The power matching unit 1082 is configured to obtain the corresponding power demand based on the total communication data volume and send the power demand to the power module 110.

[0049] In this embodiment, data from all modules of the vehicle body control device is collected during use to obtain the total communication data volume. Different power requirements corresponding to different ranges of total communication data volume are pre-defined. During implementation, the power matching unit 1082 matches the corresponding power requirements based on the total communication data volume. After obtaining the power requirements, the power module provides the corresponding power allocation to the vehicle body control device.

[0050] In one embodiment, such as Figure 2 As shown, the vehicle control device also includes a backup power module 109. The power module 109 is electrically connected to the smart entry module 100, the vehicle start module 101, and the engine remote start-stop control module 104, respectively. The backup power module 109 provides low-power standby power to the smart entry module 100, the vehicle start module 101, and the engine remote start-stop control module 104. In this embodiment, the backup power module 109 ensures that the smart entry module 100, the vehicle start module 101, and the engine remote start-stop control module 104 can operate in standby mode with low power consumption, thus enabling keyless entry, keyless start, and engine remote start-stop to be performed at any time.
