[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Figure 1 : is a structural schematic diagram of an electrically adjustable steering column welcome control system provided by an embodiment of the present invention, comprising:

[0041] The body control module 101, whose English name is "Body Control Module", abbreviated as "BCM", is used to monitor the changes of the vehicle locking status signal, the door switch status signal, the seat belt wearing status signal and the engine running status signal, and send the vehicle locking status signal, the door switch status signal, the seat belt wearing status signal and the engine running status signal to the column controller.

[0042] The column controller 102 is used to receive the vehicle locking status signal, door switch status signal, seat belt wearing status signal and engine running status signal sent by the body control module 101, and after identifying that the vehicle locking status signal, door switch status signal, seat belt wearing status signal or engine running status signal have reached a predetermined state, adjust the angle and telescopic adjustment of the electric steering column, and adjust the electric steering column to a welcoming position or a memory position. Specifically, the electric steering column is adjusted to the welcoming position according to the welcoming parameters, and the welcoming parameters include the adjustment angle of the electric steering column and the telescopic distance of the electric steering column. Among them, angle adjustment refers to adjustment in both up and down directions. When adjusting the angle, the adjustment angle of the uppermost position of the electric steering column is preferably +2°, and the adjustment angle of the lowermost position of the electric steering column is preferably -2°, that is, the total adjustment angle of the electric steering column is preferably 4°; telescopic adjustment refers to adjustment in both front and back directions. When adjusting the telescopic adjustment, the telescopic distance of the rearmost position of the electric steering column is preferably -150mm, and the telescopic distance of the frontmost position of the electric steering column is preferably +30mm, that is, the total telescopic distance of the electric steering column is preferably 180mm. Among them, the welcoming position is the uppermost position of the electric steering column and the rearmost position of the electric steering column, and the memory position is the last position of the electric steering column.

[0043] The electrically adjustable steering column 103 is connected to the steering wheel and the column controller, and is used to be controlled by the column controller 102 to perform angle adjustment and telescopic adjustment, thereby changing the position of the steering wheel.

[0044] Based on the above-mentioned electrically adjustable steering column welcome control system, the present invention also provides an electrically adjustable steering column welcome control method.

[0045] like Figure 2 As shown, in the first embodiment, the steps are specifically included:

[0046] After the driver unlocks the car, the body control module detects a change in the vehicle lock status signal and sends a vehicle lock status signal to the column controller. After the driver opens the door, the body control module detects a change in the door switch status signal and sends a door switch status signal to the column controller.

[0047] After the column controller recognizes that the vehicle lock status signal is unlocked and the door switch status signal is open, it obtains the welcome parameters and adjusts the electric steering column to the welcome position according to the welcome parameters. The welcome parameters include the adjustment angle of the electric steering column and the telescopic distance of the electric steering column. Preferably, the adjustment angle of the electric steering column is +2°, and the telescopic distance of the electric steering column is -150mm. The welcome position is the uppermost position of the electric steering column and the rearmost position of the electric steering column.

[0048] like Figure 2 As shown, in the second embodiment, the steps are specifically included:

[0049] After the driver gets in the car and closes the door, the body control module detects that the door switch status signal changes and sends the door switch status signal to the column controller. After the driver wears the seat belt, the body control module detects that the seat belt wearing status signal changes and sends the seat belt wearing status signal to the column controller.

[0050] After the column controller recognizes that the door switch status signal is closed and the seat belt wearing status signal is worn, it adjusts the electric steering column to the memory position. The memory position is the last position of the electric steering column.

[0051] like Figure 2 As shown, in the third embodiment, the following steps are specifically included:

[0052] After the driver turns off the power, the body control module detects that the engine running status signal has changed, and sends the engine running status signal to the column controller. After the driver unfastens the seat belt, the body control module detects that the seat belt wearing status signal has changed, and sends the seat belt wearing status signal to the column controller. After the driver opens the door, the body control module detects that the door switch status signal has changed, and sends the door switch status signal to the column controller.

[0053] After the column controller recognizes that the engine operation status signal is stopped, the door switch status signal is open, and the seat belt wearing status signal is not worn, it obtains the welcome parameters and adjusts the electric steering column to the welcome position according to the welcome parameters. The welcome parameters include the adjustment angle of the electric steering column and the telescopic distance of the electric steering column. Preferably, the adjustment angle of the electric steering column is +2°, and the telescopic distance of the electric steering column is -150mm. The welcome position is the uppermost position of the electric steering column and the rearmost position of the electric steering column.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
