The zero-gravity seat safety control system is configured to perform the steps of the zero-gravity seat safety control method as described in the present embodiment.
In this embodiment, the zero gravity seat assembly 1 is configured to adjust the angle of the zero gravity seat back and output a seat back angle signal. The zero-gravity seat assembly 1 comprises a seat adjusting switch 11, a backrest angle adjusting module 12 and a sitting and leaning angle linkage adjusting module 13, wherein the seat adjusting switch 11, the backrest angle adjusting module 12 and the sitting and leaning angle linkage adjusting module 13 are respectively connected with a seat controller 2. The seat adjusting switch 11 is used for adjusting the angle of the seat back and obtaining the switching value of the back angle adjustment, and outputs a seat adjusting signal to the seat controller 2, so that the seat controller 2 can judge whether the seat is manually adjusted. Backrest angle adjusting module 12, sit and lean on angle linkage adjusting module 13 and adopt hall motor drive, realize zero gravity seat backrest angle and adjust, hall motor converts seat backrest angle signal into hall signal, exports to seat controller 2 for seat controller 2 judges discernment seat backrest angle and receives 2 electric signal drive backrest angle adjusting module 12 of seat controller, sits and lean on angle linkage adjusting module 13 work.
In this embodiment, the seat controller 2 collects the switch adjustment signal and the seatback angle signal from the zero-gravity seat assembly 1 and the vehicle state information of the vehicle state module 3, and determines to output the seat driving signal based on the collected information, and drives the seatback angle adjustment module 12 and the seating angle linkage adjustment module 13 to operate, so as to adjust the seatback angle, and outputs the electrical signal to the screen module 4 for safety prompt.
In this embodiment, the vehicle state module 3 outputs vehicle state information to the seat controller 2 through vehicle CAN communication, and the seat controller 2 determines whether the zero-gravity seat assembly 1 needs to adjust the backrest angle or not and whether the screen module 4 needs to make a safety prompt or not. The vehicle status module 3 may increase or decrease the number of modules based on the degree of intelligence and safety of the system. In the embodiment, the vehicle state module 3 includes a vehicle speed module 31 and/or a transmission module 32, and the vehicle speed module 31 is used for detecting the current vehicle speed of the vehicle; the transmission module 32 is used to detect the current gear of the vehicle.
In this embodiment, the screen module 4 receives the safety prompt signal output by the seat controller 2, and outputs a safety prompt based on the safety prompt signal. The safety prompt mainly comprises the following two parts: safety prompt 1, remind the user, under the driving state, whether zero gravity seat back angle is safe at present. Safety prompt 2, remind the user, seat controller 2 will automatically adjust zero gravity seat back to safe angle.
In this embodiment, the zero-gravity seat safety control system is mainly used in a scene where a secondary driver and a passenger are used, when a vehicle is in a driving state, the primary driver and the passenger are in a driving state, and in order to ensure driving safety and avoid misoperation, the zero-gravity seat at the driving position of the primary driver cannot enter a zero-gravity posture in the driving process.
In this embodiment, according to the difference between the zero-gravity seat structure and the environment inside the vehicle, the backrest angle adjusting module 12 and the backrest angle linkage adjusting module 13 have different backrest angle adjusting ranges, and the collision safety angle in the driving state and the maximum backrest angle in the zero-gravity optimum posture also have different ranges. This is only an example: zero gravity design backrest angle 25 °; the backrest angle adjusting module 12 can adjust the backrest angle backwards by 30 degrees; the backrest angle linkage adjusting module 13 can realize 14-degree backward adjustment of the backrest angle; the collision safety angle under the driving state is less than or equal to 45 degrees; the maximum back angle for the zero gravity optimum attitude is 55 °.
In this embodiment, the seat controller 2 adjusts the backrest to the collision safety angle in the following principle:
when the vehicle is in a static state, the seat controller 2 identifies that the initial angle of the backrest adjusting module is 25 degrees; the seat and backrest angle is identified to be linked with the adjusting module 13, and the backrest angle is adjusted by 14 degrees backwards; identifying a backrest adjusting module, and adjusting the backrest angle backwards by 16 degrees; at this time, the zero-gravity seat back angle is 55 °, i.e., 25 ° +14 ° +16 ° =55 °.
When the vehicle state changes, the vehicle speed of the whole vehicle is more than 3Km/h or is not in a P gear, in order to ensure that the angle of the backrest of the zero gravity seat is less than or equal to 45 degrees, the operation is carried out through a seat controller 2: 45 ° - (25 ° +14 °) =6 °, wherein 45 ° is the collision safety angle, 25 ° is the backrest adjustment module initial angle, and 14 ° is the seating angle, and the adjustment module 13 has completed 14 ° backward adjustment. The maximum backrest angle of the zero-gravity backrest adjusting module obtained through calculation can only be adjusted by 6 degrees backwards. Since the backrest angle is adjusted 16 ° backwards when the vehicle is stationary, the backrest angle adjustment module 12 must adjust the backrest angle by a minimum of 10 ° forwards, so that the backrest angle of the zero-gravity seat is less than or equal to 45 ° in the driving state.
As shown in fig. 2, the specific control steps of a zero gravity seat safety control system are as follows:
s21, starting;
s22, judging whether the gear of the transmission is in a non-P gear or whether the vehicle speed is greater than 3km/h, if so, entering a step S23, and if not, entering a step S32;
s23, judging the position of the zero gravity seat, if the position is at the main driving position, entering the step S24, and if the position is not at the auxiliary driving position, entering the step S26;

s25, the screen module 4 carries out safety prompt 1 and the step S32 is carried out;
s26, judging whether the zero gravity seat is in a manual adjusting state, if so, entering a step S27, otherwise, entering a step S28;
s27, preferentially executing manual adjustment response, and entering the step S28;
s28, collecting the backrest angle position of the zero-gravity seat assembly 1;
s29, judging whether the backrest angle of the zero gravity seat meets a safe collision angle (namely, the backrest angle is smaller than or equal to the safe collision angle), if so, going to a step S32, and if not, going to a step S30;
s30, adjusting the backrest angle of the zero-gravity seat to a collision safety angle;
s31, carrying out safety prompt 2 through the screen module 4, and entering the step S32;
and S32, ending.
As shown in fig. 3, a principle example of the seat controller 2 adjusting the backrest angle to the safe collision angle is as follows:
s21, starting;
s33, the seat controller 2 initially calibrates the initial angle of the seat and back angle linkage adjusting module 13: 0 degree;
s34, initial angle of the backrest angle adjusting module 12: 25 °;
s35, recognizing the design backrest angle of the zero-gravity seat: 25 °;
s36, the seat controller 2 acquires the angle of the sitting and leaning angle linkage adjusting module 13: 14 degrees;
s37, identifying an angle backward adjustment value of the seat and back angle linkage adjusting module 13 through operation: 14 degrees;
and S38, acquiring the angle of the backrest angle adjusting module 12 by the seat controller 2: 41 degrees;
s39, identifying a 16-degree backward adjustment value (namely 41-25-degree = 16) of the angle of the backrest angle adjusting module 12 through operation;
s40, identifying a backward adjustment value of the zero-gravity seat backrest angle: 30 ° (i.e., 16 ° + step S37 adjusted backward from step S39);
s41, identifying the angle of the zero gravity seat backrest: 55 ° (i.e., zero-gravity seat design backrest angle 25 ° +16 ° + adjusted backward in step S39 +14 ° =55 ° adjusted backward in step S37);
