Description

Technical Field

[0001] The invention belongs to the technical field of automobile seat switch control, and in particular relates to a method for controlling seat memory calling and position storage by using a switch. Background Art

[0002] Traditional car seat memory physical switches usually use an M key and three gears (1 / 2 / 3) for seat memory call-out and position storage. This method usually requires a separate switch to be set on the car seat.

[0003] like Figure 1 As shown in the figure, the five switches are used to control the seat ventilation, heating, massage, memory / storage and one-touch reclining / reset functions. According to the CAS (Concept A Surface) definition, only one switch is used to realize the seat memory call-out / position storage function. Therefore, the switch has CAN communication function. When the number of available switches is limited, it can be considered how to reuse one switch to control two or more functions. Summary of the invention

[0004] The object of the present invention is to provide a method for controlling seat memory calling and position storage by using one switch, so as to realize the control of two or more functions by multiplexing one switch.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: The present invention provides a method for controlling seat memory calling and position storage by using a switch, which specifically comprises the following steps: Step S1: setting control strategy; Step S1.1: The seat memory switch module and the seat controller are respectively set to a memory call-out mode and a position storage mode; Step S1.2: The seat memory switch on the seat memory switch module is in the memory recall mode. Short press the seat memory switch to switch the memorized seat position. Step S1.3: Enter the position storage mode from the memory call-out mode, long press the seat memory switch, and the seat memory switch module and the seat controller enter the position storage mode at the same time; Step S1.4: Long press the seat memory switch again to complete the seat position storage and enter the memory recall mode, or automatically store the seat position after 1 minute and then exit the position storage mode and enter the memory recall mode; Step S2: specific control method; Step S2.1: Memory call-out mode; Short press the seat memory switch to call out position A, position B and position C in sequence; Step S2.2: Position storage mode; Step S2.2.1: When a certain memory recall indicator light is always on, long press the seat memory switch to enter the position storage mode, and the memory recall indicator light flashes; Step S2.2.2: After the seat memory switch module and the seat controller both enter the position storage mode, short press the seat memory switch to switch the seat position to be stored, and long press the seat memory switch again to store the current seat position in the selected position; Step S2.2.3: After the seat memory switch module and the seat controller enter the position storage mode, if there is no operation for 1 minute, the current seat position will be automatically stored in the corresponding position; Step S3: Define the name, transmission type, length and signal value of the seat memory switch signal.

[0006] Furthermore, the time range of the short press is: 50ms≤t<1s.

[0007] Furthermore, the time range of the long press is: t≥1s.

[0008] Furthermore, in step S2.2.1, when the memory recall indicator light at position A is always on, after long pressing the seat memory switch to enter the position storage mode, the memory recall indicator light at position A flashes; when the memory recall indicator light at position B is always on, after long pressing the seat memory switch to enter the position storage mode, the memory recall indicator light at position B flashes; when the memory recall indicator light at position C is always on, after long pressing the seat memory switch to enter the position storage mode, the memory recall indicator light at position C flashes.

[0009] Further, in step S2.2.1, if all memory recall indicator lights are off, the memory recall indicator light at position A flashes.

[0010] Further, in step S3, the name of the seat memory switch signal is SeatMemorySw, the sending type is Cycle, the length is 3, and the signal values ​​are described as: 0x00: No position, 0x01: Position A, 0x02: Position B, 0x03: Position C and 0x04: Long press (For memory).

[0011] Furthermore, the signal value 0x00 indicates No position, i.e., there is no currently stored position; The signal value 0x01 indicates Position A, i.e. position A; The signal value 0x02 indicates Position B, i.e. position B; The signal value 0x03 indicates Position C, i.e. position C; The signal value 0x04 indicates Long press.

[0012] The beneficial effects of the present invention are: 1. In the case of external CAS limitations or a limited number of switches, the method provided by the present invention of using one switch to control seat memory call-out and position storage can reduce the number of physical switches for car seat memory from 4 to 1, thereby reducing the number and size of exposed switches and improving the refinement of the entire vehicle.

[0013] 2. Other switches such as one-touch reclining and seat massage can also adopt the method provided by the present invention. One switch can accurately realize different functions by long pressing / short pressing. For example, the seat massage has three levels of massage intensity by default, and long pressing can enter the massage mode adjustment; one-touch reclining can be realized by short pressing, and long pressing can be realized by one-touch reset, saying goodbye to the previous crude strategy of short pressing to reverse movement.
