Drawings
The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification, illustrate embodiments of the disclosure and together with the description serve to explain the disclosure without limiting the disclosure. In the drawings:
fig. 1 is a block diagram illustrating a configuration of a vehicle controller according to an exemplary embodiment.
Fig. 2 is a block diagram illustrating a configuration of a flotation control system according to an exemplary embodiment.

Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a block diagram illustrating a configuration of a vehicle controller according to an exemplary embodiment. As shown in fig. 1, the vehicle controller 10 may include: the detection module 101 is used for detecting the gear state of the float switch 20; the obtaining module 102 is configured to obtain wading depth information of the vehicle when the float switch 20 is in a float control shift position, where the float control shift position is used to trigger the vehicle controller 10 to enter a float control mode; and the control module 103 is used for entering a floating control mode when the wading depth information meets the preset floating control condition so as to execute the floating control operation.
In the present disclosure, the float switch 20 has a float control gear for triggering the vehicle controller 10 to enter the float control mode and a non-float control gear for triggering the vehicle controller 10 to exit the float control mode. When the user judges that the vehicle controller 10 needs to enter the floating control mode according to the current vehicle wading state data, the vehicle controller 10 can be triggered to enter the floating control mode by setting the floating switch 20 to the floating control gear. In addition, the float switch 20 being set to the float control position may also be due to a user's erroneous operation.
The wading depth information may include a wading depth of the vehicle, which is used to represent a distance between a lowest plane of the vehicle and the water surface, and may be acquired by a wading depth detection device 30 (e.g., a hydraulic sensor, a radar, etc.), and the wading depth detection device 30 may be connected to the acquisition module 102. The wading depth information acquiring method may be that when the detecting module 101 detects that the float switch 20 is in the float control gear, the acquiring module 102 sends a wading depth information request to the wading depth detecting device 30, the wading depth detecting device 30 detects wading depth information of the vehicle after receiving the wading depth information request, then sends the detected wading depth information to the acquiring module 102, and the acquiring module 102 receives the wading depth information. The wading depth information may be acquired in such a manner that the wading depth detection device 30 sends the detected wading depth information to the acquisition device 102 at a fixed cycle, and the acquisition device 102 receives the wading depth information.
After the wading depth information is acquired, the control module 103 determines whether the wading depth information meets a preset floating control condition. For example, when the wading depth of the vehicle is greater than or equal to a preset water depth threshold value, determining that the wading depth meets a preset floating control condition; and when the wading depth of the vehicle is smaller than a preset water depth threshold value, determining that the wading depth does not meet the preset floating control condition. The water depth threshold may be a value set by a user or a default empirical value. When it is determined that the wading depth information satisfies the preset floating control condition, the vehicle controller 10 may determine that the vehicle controller 10 actually needs to enter the floating control mode at present, and accordingly, the vehicle controller 10 may enter the floating control mode accordingly to start the floating control operation.
When the vehicle controller 10 enters the float control mode, the float control operation is performed. Wherein the flooding control operation may include at least one of: controlling the engine to be shut down; controlling the closing of an intake pipe valve arranged on an intake pipeline; controlling the valve of an exhaust pipe valve arranged on an exhaust pipeline to close; controlling the vehicle-mounted electric appliance to be closed; controlling the skylight controller to switch into a manual mode; and controlling the power motor to be started.
In the present disclosure, since the intake duct is communicated with the engine compartment, water is not allowed to enter, and therefore, an intake pipe valve may be installed on the intake duct. The intake valve may be comprised of an actuator motor, a position sensor, a valve mechanism, and a valve controller, wherein the position sensor is used to detect whether the intake valve is fully opened or closed. The control module 103 sends an instruction to the valve controller, the valve controller controls the operation of the execution motor to drive the operation of the valve mechanism, the position sensor detects whether the valve of the air inlet pipe is completely closed in the operation process of the valve mechanism, and if the valve is not completely closed, the valve controller controls the valve mechanism to continue to operate until the valve is completely closed. When the vehicle controller 10 enters the float control mode, the intake pipe valve may be controlled to be closed. Whether this valve is closed completely through position sensor detection, like this, can avoid causing the engine stall or damage because of the vehicle wades into engine compartment from the admission line when dark.
The exhaust duct leads from the engine compartment to the end of the vehicle. To prevent water from entering the engine compartment through the exhaust valve when the vehicle is wading, an exhaust valve may be mounted in the exhaust duct. The exhaust pipe valve may be composed of an actuator motor, a position sensor, a valve mechanism, and a valve controller, and the vehicle controller 10 may control the valve controller by an instruction to close the exhaust pipe valve. The principle of the valve controller controlling the closing of the exhaust pipe valve is the same as that of the intake pipe valve, and the detailed description is omitted here.
Preferably, a catalyst may be disposed at the rear of the vehicle, and the exhaust pipe valve may be disposed downstream of the catalyst on the exhaust pipe, wherein upstream and downstream are defined in the direction of gas flow, for example, when exhausting from the exhaust pipe, if gas passes through the first position and then passes through the second position, the first position may be considered to be upstream of the second position, and the second position may be considered to be downstream of the first position. By arranging the exhaust pipe valve downstream of the catalyst on the exhaust pipe, the exhaust gas first passes through the catalyst and then passes through the exhaust pipe valve when the exhaust pipe is exhausted. Thus, the exhaust pipe valve is closed when the float control operation is performed, and the catalyst can be prevented from accumulating water.
Alternatively, and preferably, two exhaust pipes may also be led out from the engine compartment, which are respectively located at the left side and the right side of the tail of the vehicle, and an exhaust pipe valve is respectively arranged at the downstream of the catalyst on each exhaust pipe, and the vehicle controller 10 may control the valve controller through commands to close and open the exhaust valves, so as to realize the dredging and blocking of the left and right exhaust pipes.
When entering the float control mode, the vehicle controller 10 may forcibly turn off the engine by command. Therefore, the problem that the engine is flamed out or damaged in different degrees due to the fact that water directly enters the engine through the air inlet or the exhaust pipe opening because the vehicle wades too deeply can be prevented. In addition, for the new energy automobile, a power motor is arranged on the new energy automobile and used for providing power for the automobile when the automobile is in an electric mode. When the vehicle enters the floating control mode, the vehicle controller 10 may forcibly start the power motor through an instruction to continue to provide power output for the vehicle, so as to ensure that the hybrid vehicle can continue to move out of the wading area with power after the engine is turned off.
The skylight controller has a manual mode and an electric mode and can be used for controlling the opening and closing of the skylight. When the sunroof controller is in the manual mode, the user needs to push the sunroof glass to open the sunroof, and pull the sunroof glass to close the sunroof. When the skylight controller is in the electric mode, a user can realize the automatic opening of the skylight by pressing the skylight automatic opening switch and realize the closing of the skylight by pressing the skylight automatic closing switch. When the vehicle enters the floating control mode, the vehicle controller 10 sends an instruction to control the skylight controller to be switched to the manual mode, and when a vehicle power system is abnormal, the skylight can be manually opened, so that a user can smoothly escape under an emergency condition.
The vehicle-mounted electric appliances can comprise vehicle-mounted air conditioners, vehicle-mounted navigation electric appliances and the like. When entering the floating control mode, the vehicle controller 10 can control the vehicle-mounted electrical appliance to be turned off through an instruction, so as to achieve the purposes of power saving and safety.
Through the technical scheme, even if the floating switch is placed in the floating control gear position due to inaccurate judgment of the vehicle wading depth by the user or misoperation of the user, before the vehicle controller enters the floating control mode, the vehicle controller is secondarily confirmed whether to enter the floating control mode or not by judging whether the vehicle wading depth meets the preset floating control condition. Like this, can avoid making vehicle controller mistake entering float control mode because of the user judges the inaccurate or user maloperation of vehicle wading depth, lead to the engine mistake to close the scheduling problem, improve the accuracy that float control mode triggered to effectively reduce the vehicle and take place dangerous possibility, promote user's personal and property safety.
Optionally, the control module 103 may be further configured to output floating control confirmation information when the vehicle wading depth information does not satisfy the floating control condition, where the floating control confirmation information is used to confirm to a user whether to trigger the vehicle controller to enter the floating control mode; receiving a confirmation response message input by a user; and entering the floating control mode to execute the floating control operation under the condition that the confirmation response message indicates that the user confirms to trigger the vehicle controller to enter the floating control mode.
In addition, in order to avoid that the vehicle controller 10 enters the floating control mode due to the false triggering of the user or the inaccurate judgment on the vehicle wading depth, when the floating switch 20 is in the floating control gear and the control module 103 determines that the wading depth information does not meet the preset floating control condition, the vehicle controller 10 may output floating control confirmation information for confirming to the user whether the vehicle controller 10 needs to be triggered to enter the floating control mode. When the user receives the float control confirmation message, a confirmation response message is input to indicate whether to continue triggering the vehicle controller 10 to enter the float control mode. When the received user confirmation response message indicates that the user confirms to trigger the vehicle controller 10 to enter the floating control mode, the vehicle controller 10 may enter the floating control mode; when the received user confirmation information indicates that the user refuses to trigger the vehicle controller 10 to enter the floating control mode, it indicates that the current trigger may be a false trigger, and the vehicle controller 10 does not enter the floating control mode. And preferably vehicle controller 10 may reset float switch 20 to the non-float control gear.
Optionally, the detection module 101 may also be configured to detect whether the high-voltage bus leaks electricity; the control module 103 may also be configured to disconnect the high-voltage bus if the detection module 101 detects a leakage of the high-voltage bus.
In this disclosure, the high voltage bus voltage of the new energy vehicle is up to several hundred volts, and if the leakage occurs, the personal safety of the customer may be threatened, so that the leakage protection measure is implemented for the vehicle, and a circuit breaker and a leakage detection module may be installed on the high voltage bus. The detection module 101 detects whether the leakage phenomenon occurs on the high-voltage bus in real time through the leakage detection module. When the detection module 101 detects that the high-voltage bus is in a leakage state, an instruction for disconnecting the circuit breaker is sent to the control module 103, and after receiving the instruction, the control module 103 controls the circuit breaker to disconnect the high-voltage bus.
The control module 103 may be further configured to exit the floating control mode and reset the floating switch 20 to the non-floating control position after entering the floating control mode and when the wading depth information becomes unsatisfied with the floating control condition, so as to save user operations and facilitate a user forgetting to manually reset the floating switch 20; alternatively, after entering the floating control mode, when the wading depth information becomes that the floating control condition is not satisfied, first prompt information for prompting the user to reset the float switch 20 to the non-floating control shift position so that the vehicle controller 10 exits the floating control mode is output.
In an embodiment of the present disclosure, after entering the floating control mode, the obtaining module 102 may obtain wading depth information of the vehicle in real time, the control module 103 determines whether the preset floating control condition is still satisfied according to the wading depth information, and when it is determined that the wading depth information does not satisfy the floating control condition, the control module 103 directly controls the vehicle controller 10 to exit the floating control mode, and resets the floating switch 20 to the non-floating control gear.
In another embodiment of the present disclosure, after entering the floating control mode, the obtaining module 102 obtains wading depth information of the vehicle in real time, and when the control module 103 determines that the wading depth information does not satisfy the floating control condition, the control module 103 may output a prompt message to remind a user to manually reset the floating switch 20 to a non-floating control gear, so that the vehicle controller 10 forcibly exits the floating control mode.
Optionally, the control module 103 may be further configured to, after exiting the floating control mode, perform at least one of the following control operations: controlling an air inlet pipe valve arranged on an air inlet pipeline to open; and the exhaust pipe valve arranged on the exhaust pipeline is controlled to be opened, so that the vehicle can be restarted conveniently.
Optionally, the control module 103 may be further configured to output a second prompt after entering the float control mode, the second prompt indicating that the vehicle controller 10 is currently in the float control mode.
In one embodiment of the present disclosure, the prompt message may indicate the mode in which the vehicle controller 10 is currently located through the color of the indicator light, the display state of the indicator light. For example, when the indicator light is red, it indicates that the vehicle controller 10 is currently in the floating control mode, and when the indicator light is green, it indicates that the vehicle controller 10 is currently in the non-floating control mode. Alternatively, when the indicator light is flashing, it indicates that the vehicle controller 10 is currently in the floating control mode, and when the indicator light is constantly on, it indicates that the vehicle controller 10 is currently in the non-floating control mode. In addition, the prompt message may also remind the user of the current mode of the vehicle controller 10 through voice broadcast.
