Detailed Description
As shown in fig. 1, a control method for avoiding the influence of air tightness when an automobile back door is electrically closed comprises the following steps:
1) the contribution ratio of the influence of the vehicle door, the vehicle window and the air conditioner on the air tightness is set in the backdoor controller, wherein,
the contribution of a single vehicle door in an opening state is 0%, the contribution of a single vehicle door in a closing state is 10%, and the total contribution of four vehicle doors in a closing state accounts for 40%;
the contribution of a single window in an opening state is 0%, the contribution of a single window in a closing state is 5%, and the total contribution of four windows in a closing state accounts for 20%;
the contribution of the air conditioner in the off state is 0%, the contribution of the air conditioner in the low wind power on state is 5%, the contribution of the air conditioner in the medium wind power on state is 15%, the contribution of the air conditioner in the high wind power on state is 20%, and the total contribution of the air conditioner in the on state accounts for 40%;
taking the car door as an example, the contribution of a single car door in a closed state is 10%, the total contribution of four car doors in a closed state accounts for 40%, then one car door is in an open state, the contribution of three car doors in a closed state is 30%, and similarly, the contribution of two car doors in a closed state is 20%.
Taking the window as an example, the contribution of a single window in the closed state is 5%, the total contribution of four windows in the closed state accounts for 20%, then one window is in the open state, the contribution of three windows in the closed state is 15%, and similarly, the contribution of two windows in the closed state is 10%.
Taking the air conditioner as an example, the contribution of the air conditioner in the high wind power on state is 20%, and the total contribution ratio of the air conditioner in the high wind power on state is 5% +15% +20% =40% in sum.
2) When the backdoor is in an open state, a user sends a backdoor closing instruction through a switch, and after receiving the closing instruction, the backdoor controller firstly monitors four-door state signals, vehicle window state signals and air conditioner state signals through a CAN network and calculates the total contribution ratio according to the monitored state signals;
3) and the backdoor controller sends a car window linkage opening instruction to the car window controller according to the calculated total contribution ratio, the car window controller receives the instruction and then controls the opening degree of the car window, and meanwhile, the backdoor controller drives the backdoor to close.
Further, when the calculated total contribution percentage is 100% in the step 3), the backdoor controller is linked with the window controller to open 1/2 the window.
Further, when the calculated total contribution accounts for 80% -100% in the step 3), the backdoor controller is linked with the window controller to open the window 1/4.
Further, when the calculated total contribution accounts for 40% -80% in the step 3), the backdoor controller is linked with the window controller to open the window in 1/8 states.
Further, when the calculated total contribution ratio is less than 40% in the step 3), the backdoor controller does not link with the window controller and only drives the backdoor to close.
That is to say, when the backdoor is in an open state, the user closes the backdoor through the operation switch, the backdoor controller immediately monitors four-door state signals, window state signals and air conditioner state signals sent by corresponding nodes on the CAN network after receiving a door closing instruction, and the total contribution ratio is calculated according to the signal values. The control parameters corresponding to different total contribution ratio ranges are as follows:
a. when the calculated total contribution ratio =100%, the backdoor controller sends out a window linkage 1/2 opening instruction signal while driving the backdoor to close, the instruction requires the window opening degree to be in a half-open state, and the window controller receives the instruction and then links the window to be in the half-open state;
b. when the calculated total contribution ratio is between 80% and 100%, the backdoor controller sends a window linkage 1/4 opening instruction while driving the backdoor to close, the instruction requires the window opening degree to be in a 1/4 state, and after receiving the instruction, the window controller links the window to be in a 1/4 state (if a certain side window is in an opening state, the side window ignores the opening instruction);
c. when the calculated total contribution ratio is between 40% and 80%, the backdoor controller drives the backdoor to close and simultaneously sends a window linkage 1/8 opening command to the backdoor controller, the command requires the window opening degree to be in a 1/8 state, and after the window controller receives the command, the window is linked to be opened to a 1/8 state (if a certain side window is in an opening state, the side window ignores the opening command at this time);
d. when the calculated total contribution ratio is in the range of 40% or less, the back door controller does not need to perform window linkage control, and only needs to perform back door closing.
Further, when the backdoor completes the electric closing action, the backdoor controller sends a window linkage closing instruction to the window controller, and the window controller controls the window to recover to a closing state.
The vehicle window linkage is only convenient for non-user-enabled control for reducing the influence of the air tightness of the whole vehicle when the door is electrically closed, so that the control method for the vehicle window linkage closing is provided for improving the comfort and the safety, and the purpose of reducing the influence of the control on the use of a user is achieved. The specific control method comprises the following steps:
when the closing command enables the driven electric closing action of the back door to be completed (including stopping from the electric closing to the full-closing position or enabling the back door to stop or executing the opening action by operating a switch in the action process of a user), the back door controller sends a window linkage closing command signal, and after receiving the command, the window controller controls the window in the closing state to be closed again to the full-closing state when the linkage is opened.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and modifications of the present invention by those skilled in the art are within the scope of the present invention without departing from the spirit of the present invention.
