Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle charging port cover control, in particular to a control method and system suitable for vehicle level charging port cover position failure. BACKGROUND

[0002] Electric vehicles use batteries as a source of power, and the connection interface between the vehicle body and the charging pile is a charging port cover. The control method of the charging port cover has gradually switched from mechanical control to electric control. The electric control charging port cover module of the prior art is usually connected to the vehicle body domain controller through a wire harness for driving. In this process, if the vehicle is running out of power, the wire harness connection is poor, the controller signal is lost, or the charging port cover module is abnormally powered off during execution, the position signal of the charging port cover module will be lost, the vehicle body domain controller will receive invalid positions, and the charging port cover cannot be normally opened or closed, causing certain inconvenience to the vehicle charging.

[0003] Currently, the existing technology generally uses a scheme of recording fault phenomena and performing software initialization reset. This scheme requires the customer to go to a 4S store, and when the vehicle is in a power feeding state and cannot be started, the maintenance personnel also need to provide on-site services, which brings many inconveniences and seriously affects the user experience. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a control method and system suitable for vehicle level charging port cover position failure, which can automatically perform charging port cover initialization operation and drive the charging port cover to restore the correct position state when the vehicle is in a vehicle level charging port cover position failure state, has high control accuracy, fast response speed, and does not affect the normal experience of the customer.

[0005] To solve the above technical problems, the technical scheme adopted by the present application is:

[0006] I. A control method suitable for vehicle level charging port cover position failure

[0007] The present application provides a control method suitable for vehicle level charging port cover position failure, which includes the following strategies:

[0008] S1, according to the charging port cover initialization state feedback signal and the vehicle power gear information, performing charging port cover initialization running control;

[0009] S2, according to the current received voice instruction, central control instruction and remote instruction, judging the current priority execution charging port cover control command;

[0010] S3, when the priority execution charging port cover unlocking command is executed, the corresponding charging port cover unlocking driving control is performed according to the real-time position state of the charging port cover;

[0011] S4, when the charging port cover closing command is executed preferentially, then the charging port cover closing driving control is performed according to the real-time position state of the charging port cover.

[0012] Preferably, the charging port cover initialization running control comprises:

[0013] When the charging port cover is not in the initialization state (fail) and the vehicle power gear is switched from non-ON gear to ON gear, the initialization instruction is sent to the charging port cover module through the vehicle body domain controller after timing T0, and the initialization instruction is stopped after the charging port cover is in the initialization state (success).

[0014] When the initialization instruction sending time exceeds T1, the charging port cover initialization failure alarm information is sent to the vehicle central control system through the vehicle body domain controller.

[0015] Preferably, the specific priority of the voice instruction, the central control instruction and the remote instruction is: voice instruction>central control instruction>remote instruction; that is, when the charging port cover unlocking / closing command sent by the driver voice is received, the command is executed preferentially, then the charging port cover unlocking / closing command sent by the vehicle central control system is executed, and finally the charging port cover unlocking / closing command sent by the remote charging device is executed.

[0016] Preferably, the charging port cover unlocking driving control comprises:

[0017] If the charging port cover position state is the closed state M2, the opening command is sent to the charging port cover module through the vehicle body domain controller to drive the charging port cover to open and timing t1, when t1

[0018] If the charging port cover position state is the failure state M0, the closing command is first sent to the charging port cover module through the vehicle body domain controller to drive the charging port cover to close and timing t2, when t2

[0019] When t2≥preset time T3 or t3≥preset time T4, the charging port cover position state is still in the failure state M0, and the charging port cover position failure alarm information is sent to the vehicle central control system through the vehicle body domain controller.

[0020] Preferably, the charging port cover locking drive control comprises:

[0021] If the charging port cover position state is the open state M1 or the failure state M0, a closing command is sent by the vehicle body domain controller to the charging port cover module to drive the charging port cover to close and timing t4, when t4 < preset time T5, the charging port cover position state changes to the closed state M2, and the closing command is stopped; when t4 >= preset time T5, the charging port cover position state still does not change to the closed state M2, and charging port cover locking failure alarm information is sent by the vehicle body domain controller to the vehicle central control system.

[0037] In order to make the purpose, technical scheme and advantages of the application clearer, the application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and do not limit the application. In addition, the technical features involved in each embodiment of the application described below can be combined with each other as long as they do not conflict with each other.

[0038] It should be pointed out that according to the needs of implementation, each step / component described in the present application can be split into more steps / components, or two or more steps / components or part of the operation of the steps / components can be combined into a new step / component to achieve the purpose of the application.

[0039] Embodiment one provides a control method suitable for whole vehicle level charging port cover position failure, aiming at the position signal loss of the charging port cover module, so that the body domain controller receives invalid position information, and then cannot normally open or close the charging port cover. The problem is solved by initializing the charging port cover and performing position reset logic control, and then driving the charging port cover to restore the correct position state.

[0040] Specifically includes:

[0041] I. Charging port cover initialization judgment and control:

[0042] For example,Figure 1 As shown, when the initialization status signal of the charging port cover is 0 (fail), if the vehicle power position is detected to switch from OFF / ACC / START to ON, and the timing after the position switch satisfies t=T0, the domain controller drives the charging port cover to perform initialization operation until the initialization status signal of the charging port cover is 1 (success), at which point the initialization command stops. The driving time t<T1.

[0043] 2. When any charging port cover unlock command is received:

[0044] (1) As Figure 2 As shown, when any charging port cover unlock command is received, if the charging port cover is in the closed state M2, the domain controller sends an open charging port cover command to drive the charging port cover to open, and starts timing t < T2. If the charging port cover position changes to M1 within this time period, the drive command is stopped. If the charging port cover position is still M2 when t ≥ T2, the drive command is stopped and the state is reset to zero.

[0045] (2) Figure 3 As shown, when any charging port cover unlock command is received, if the charging port cover is in an invalid state M0, the domain controller sends a close command to drive the charging port cover to close, and starts the timing module t < T3. If the charging port cover is in a closed state M2 during this time period, an open command is sent to drive the charging port cover to open, and the timing starts t < T4. If the charging port cover changes to M1 during this time period, the driving command stops. If the charging port cover is still in a state M0 when t ≥ T4, the driving command is stopped and reset to zero.

[0046] 3. When any charging port cover lock command is received

[0047] like Figure 4 As shown, when any charging port cover lock command is received, if the charging port cover is in the open state M1 or the invalid state M0, the domain controller sends a command to close the charging port cover, driving the cover to close, and starts timing t < T5. If the charging port cover changes to the closed state M2 within this time period, the drive command stops. If the charging port cover has not changed to M2 by t ≥ T5, the drive command is stopped and reset to zero.

[0048] Example 2: This example provides a control method and system for the failure of the charging port cover position at the vehicle level, which mainly includes the following control strategies:

[0049] S1, based on the charging port cover initialization status feedback signal and vehicle power level information, perform initialization operation control of the charging port cover;

[0050] S2, judging the current priority execution of the charging port cover control command according to the current received voice instruction, central control instruction and remote instruction;

[0051] S3, when the priority execution of the charging port cover unlocking command is executed, corresponding charging port cover unlocking driving control is performed according to the real-time position state of the charging port cover;

[0052] S4, when the priority execution of the charging port cover locking command is executed, corresponding charging port cover locking driving control is performed according to the real-time position state of the charging port cover.

[0053] Further, the charging port cover initialization running control comprises:

[0054] When the charging port cover is not in the initialization state (fail) and the vehicle power gear is switched from non-ON gear to ON gear, the initialization instruction is sent to the charging port cover module through the vehicle body domain controller after timing T0, and the initialization instruction is stopped after the charging port cover is in the initialization state (success).

[0055] When the initialization instruction sending time exceeds T1, the charging port cover initialization failure alarm information is sent to the vehicle central control system through the vehicle body domain controller.

[0056] Further, the specific priority of the voice instruction, central control instruction and remote instruction is: voice instruction > central control instruction > remote instruction; that is, when the charging port cover unlocking / locking command sent by the driver voice is received, the command is executed first, then the charging port cover unlocking / locking command sent by the vehicle central control system is executed, and finally the charging port cover unlocking / locking command sent by the remote charging device is executed.

[0057] Further, the charging port cover unlocking driving control comprises:

[0058] If the charging port cover position state is the closed state M2, the opening command is sent to the charging port cover module through the vehicle body domain controller to drive the charging port cover to open and timing t1, when t1 < preset time T2, the charging port cover position state changes to the open state M1, and the opening command is stopped, when t1 ≥ preset time T2, the charging port cover position state is still the closed state M2, and the charging port cover unlocking failure alarm information is sent to the vehicle central control system through the vehicle body domain controller.

[0059] If the charging port cover position state is the failure state M0, first, the vehicle body domain controller sends a closing command to the charging port cover module to drive the charging port cover to close and counts t2. When t2 < the preset time T3, the charging port cover position state changes to the closing state M2, and the vehicle body domain controller sends an opening command to the charging port cover module to drive the charging port cover to open and counts t3. When t3 < the preset time T4, the charging port cover position state changes to the opening state M1, and the sending of the opening command is stopped.

[0060] When t2 ≥ the preset time T3 or t3 ≥ the preset time T4, the charging port cover position state is still the failure state M0, and the vehicle body domain controller sends charging port cover position failure alarm information to the vehicle central control system.

[0061] Further, the charging port cover locking drive control comprises:

[0062] If the charging port cover position state is the opening state M1 or the failure state M0, the vehicle body domain controller sends a closing command to the charging port cover module to drive the charging port cover to close and counts t4. When t4 < the preset time T5, the charging port cover position state changes to the closing state M2, and the sending of the closing command is stopped. When t4 ≥ the preset time T5, the charging port cover position state has not changed to the closing state M2, and the vehicle body domain controller sends charging port cover locking failure alarm information to the vehicle central control system.
