[0022] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0023] Figure 1 The structural schematic diagram of the control system of the camping vehicle expansion mechanism provided by the embodiment of the present invention is shown. As Figure 1 shown, the control system of the camping vehicle expansion mechanism includes: a main power contactor 1, an expansion mechanism control box 2 connected to the main power contactor 1, a controller 3 communicatively connected to the expansion mechanism control box 2 and the main power contactor 1, and at least one motor M connected to the expansion mechanism control box 2, and the controller 3 is communicatively connected to the expansion mechanism control box 2 and the main power contactor 1; the controller 3 detects the operating state information of the camping vehicle and the power state information S7 of the expansion mechanism, and outputs a power-on control signal C2 to the expansion mechanism control box according to the operating state information and the power state information S7, and the expansion mechanism control box controls the expansion mechanism to extend or retract according to the received switch control signal C2.

[0024] In the embodiment of the present invention, the controller 3 detects the operating state information of the camping vehicle, outputs a power-on control signal C1 according to the operating state information, controls the main power contactor 1 to perform a closing operation according to the power-on control signal C1, supplies power to the expansion mechanism, and the controller 3 receives the power state information S7 fed back by the main power contactor 1. The controller 3 determines whether the expansion mechanism of the camping vehicle meets the working conditions according to the operating state information and the power state information S7. If it is detected that the expansion mechanism meets the working conditions, the controller 3 outputs a power-on control signal C2 to the expansion mechanism control box, permitting the expansion mechanism control box 2 to control the expansion mechanism to work; otherwise, the power-on control signal C2 is not output.

[0025] The operating state information includes: whether the parking brake of the camping vehicle is in the parking state, whether the door is closed in place, whether the camping mode switch is turned on, and whether the vehicle speed of the camping vehicle is 0. In the embodiment of the present invention, after the camping mode switch of the camping vehicle is turned on, the controller 3 directly receives the feedback state signal S6 that the vehicle is in the camping state, and the controller 3 also receives the parking state signal S4 fed back when the vehicle tightens the parking brake and is in the parking state, and the door position state signal S5 fed back when the door is not closed in place. The controller 3 also receives message information through CAN communication, and calculates the state value of the vehicle speed being 0 after parsing the vehicle speed data from the message information.

[0026] In an embodiment of the present invention, if it is detected that the camping vehicle simultaneously satisfies that the camping mode switch is turned on, the parking brake is tightened and in the parking state, and the speed of the camping vehicle is 0, it is determined that the expansion mechanism of the camping vehicle meets the power-on condition. The controller 3 outputs a power-on control signal C1 to the main power contactor 1 to control the main power contactor 1 to supply power to the expansion mechanism. The main power contactor 1 feeds back power state information S7 to the controller 3. After the controller 3 receives the power state information S7 that the main power contactor 1 has been attracted and the working condition is normal, if it is detected that the power-on control signal is valid and lasts for a first duration, and the vehicle door is closed, it is determined that the expansion mechanism of the camping vehicle meets the working condition, and a startup control signal C2 is output to the expansion mechanism control box 2, so that the expansion mechanism control box 2 can control the expansion mechanism to extend or retract. If it can be ensured that the vehicle door is closed, the expansion mechanism will extend or retract, avoiding the running interference between the expansion mechanism and the passenger door, and ensuring the rationality and reliability of the expansion mechanism action control.

[0027] Based on the same concept, an embodiment of the present invention further provides a control method for the expansion mechanism of a camping vehicle, as Figure 2 shown. The control method for the expansion mechanism of the camping vehicle is applied to the controller and includes:

[0028] Step S11: Detect the operating state information of the camping vehicle through the controller.

[0029] In an embodiment of the present invention, it is detected whether the parking brake of the camping vehicle is in the parking state, whether the vehicle door is closed in place, and whether the camping mode switch is turned on through a port connected to the camping vehicle; the running data of the camping vehicle is obtained through a CAN communication interface wirelessly communicating with the camping vehicle, and whether the speed of the camping vehicle is 0 is detected according to the running data.

[0030] Step S12: Output a power-on control signal according to the operating state information to control the main power contactor to supply power to the expansion mechanism, and receive the power state information fed back by the main power contactor.

[0031] Optionally, it is determined whether the expansion mechanism meets the power-on condition according to the operating state information. If it is detected that the camping vehicle simultaneously satisfies that the camping mode switch is turned on, the parking brake is tightened and in the parking state, and the speed of the camping vehicle is 0, it is determined that the expansion mechanism of the camping vehicle meets the power-on condition. If the expansion mechanism meets the power-on condition, a power-on control signal is output to the main power contactor to control the main power contactor to close and supply power to the expansion mechanism. The main power contactor feeds back the power state information that the main power contactor is closed to the controller. The controller receives, through a power detection port connected to the main power contactor, the power state information indicating whether the main power contactor has been attracted and the working condition is normal fed back by the main power contactor.

[0032] Step S13: Determine whether the expansion mechanism of the camping vehicle meets the working conditions according to the operating status information and the power supply status information.

[0033] If it is detected that the power-on control signal is valid and lasts for a first duration, the main power contactor has been energized and the working condition is normal, and the door has been closed, it is determined that the expansion mechanism of the camping vehicle meets the working conditions. The first duration can be set as needed, preferably 10 s.

[0034] Step S14: If it is detected that the expansion mechanism meets the working conditions, output a power-on control signal to the expansion mechanism control box to permit the expansion mechanism control box to control the expansion mechanism to work; otherwise, stop outputting the power-on control signal.

[0035] If it is detected that the expansion mechanism meets the working conditions, output a power-on control signal to the expansion mechanism control box to permit the expansion mechanism control box to control the expansion mechanism to work. After receiving the power-on control signal, the expansion mechanism control box may need to control the expansion mechanism to extend or retract.

[0036] In an embodiment of the present invention, if the controller currently outputs the power-on control signal state, and if it is detected that no power-on control signal is output to the expansion mechanism control box within a second duration, control is performed to stop outputting the power-on control signal to the main power contactor, that is, cut off the power supply of the main power contactor. The second duration can be set as needed and is not limited herein, preferably 30 min. If the power supply status information fed back by the main power contactor is invalid, that is, the main power contactor fails to close successfully, or the camping mode signal of the camping vehicle is invalid, or the parking signal is invalid, or the vehicle speed is not 0, or the door open signal is invalid, stop outputting the power-on control signal to the expansion mechanism.

[0037] In an embodiment of the present invention, in the camping mode, the controller sends CAN communication data and the instrument continuously prompts that the vehicle is prohibited from driving! If it is detected that the parking brake is not pulled (the S4 signal is invalid) at this time, the instrument prompts the driver to tighten the parking brake. That is, in the camping mode, it is one of the necessary conditions for the controller to output the power-on control signal and control the expansion mechanism to be powered on.

[0038] Detecting that the feedback signal of the main power contactor is normal is one of the necessary conditions for outputting the start-up control signal and permitting the extension mechanism to work. If the feedback signal of the main power contactor is not detected, the start-up control signal will not be output, or the already output start-up control signal will be disconnected, and the extension mechanism cannot work or will stop working; then the power-on control signal output will be stopped, the main power supply of the extension mechanism will be turned off, and the instrument will display a fault with the extension compartment power contactor. When the detected signal feedback from the main power contactor is abnormal, the output of the start-up control signal will be disconnected and the extension mechanism will stop working; then the power-on control signal output will be stopped, the main power supply of the extension mechanism will be turned off, and the instrument will display a fault with the extension compartment power contactor.

[0039] The logic for permitting the extension mechanism to work is as follows: First, the conditions for the power-on process of the extension mechanism need to be met to supply power to the control box of the extension mechanism. Second, the conditions for permitting the extension mechanism to start up should be met, and a start-up control signal should be input to the control box of the extension mechanism to permit the control box to control the motor of the extension mechanism to work, realizing the extension and retraction functions of the extension mechanism.

[0040] The control method of the camping vehicle extension mechanism in the embodiment of the present invention, starting from the perspectives of improving the reliability of the extension mechanism's electronic control system, reducing power consumption, and preventing interference with the movement of the lower passenger door, can effectively avoid working conditions such as interference between the extension mechanism and the lower passenger door movement and abnormal out-of-control by controlling and managing the main power supply of the extension mechanism and the permitted start-up control signal. Through the contactor working state detection and feedback signal function, combined with other signals for comprehensive control in the start-up control process and abnormal working condition identification control process of the extension mechanism, it is possible to prevent the uncontrollability of the extension mechanism's electronic control system when the contactor gets out of control or the contactor adheres. If it is detected that the contacts of the main power contactor are abnormally adhered, the start-up control signal output can be stopped according to the signal detected and feedback from the contactor state, realizing the shutdown of the extension mechanism and at the same time the instrument will prompt a contactor fault.

[0041] The control method of the camping vehicle extension mechanism in the embodiment of the present invention detects the operating state information of the camping vehicle through a controller; outputs a power-on control signal according to the operating state information to control the main power contactor to supply power to the extension mechanism, and receives the power state information feedback from the main power contactor; determines whether the extension mechanism of the camping vehicle meets the working conditions according to the operating state information and the power state information; if it is detected that the extension mechanism meets the working conditions, outputs a start-up control signal to the control box of the extension mechanism to permit the control box of the extension mechanism to control the extension mechanism to work; otherwise, stops outputting the start-up control signal, which can effectively avoid working conditions such as interference between the extension mechanism and the lower passenger door movement and abnormal out-of-control, improve the reliability of the extension mechanism's electronic control system, and reduce power consumption.
