For a specific adjustment method of the left clamping assembly, reference is made to the adjustment method of the right clamping assembly in the left turning of the previous embodiment, and details are not repeated here.
According to one embodiment of the invention, the lateral acceleration of the vehicle is obtained by the following formula:
wherein, a Side wall Represents lateral acceleration, V represents vehicle speed, L represents front-rear wheel base, K represents front wheel base, and Q represents steering wheel angle.
Specifically, as shown in fig. 4, during the turning of the automobile, since the turning radius R is changed in real time along with the turning angle during the actual vehicle motion, a calculation model can be derived based on the AckMann principle:
turning radius R = wheel base L/sin (β), where curve inside wheel angle β = wheel base K × steering wheel angle Q, and curve outside wheel angle ctg α = ctg β + K/L, then turning radius R = L/sin (K × Q) is derived and substituted into the lateral acceleration formula a = V 2 The above formula (1) can be obtained. Since the wheelbase L and K of the front and rear wheels are fixed values, the lateral acceleration a can be obtained by substituting the vehicle speed V and the steering wheel angle Q into the formula (1) Side wall 。
In another embodiment of the present invention, the lateral acceleration may be acquired by a lateral acceleration sensor of the vehicle.

Specifically, as shown in fig. 5, when the vehicle is driven to a slope or a continuous floating road, the human body pressure can be calculated by the following formula:
wherein, F On the upper part Indicating the human body pressure when the vehicle is operating uphill, F Lower part The pressure of a human body when the vehicle is in a downhill running state is represented, m represents the weight of the human body, g represents the acceleration of gravity, α represents a ramp angle, and a represents the acceleration.
Further, the ramp angle may be calculated by the following formula:
where α represents a ramp angle, ft represents a driving force of the vehicle, ff represents a rolling resistance of the vehicle, fw represents an air resistance of the vehicle, G represents a gravity of the vehicle, me represents an engine torque, i g Representing the current hill-climbing speed ratio, i, of the engine 0 Representing the final reduction ratio, eta T representing the efficiency of the transmission system, r representing the radius of the wheels, mu representing the friction coefficient between the wheels and the road, N representing the positive pressure of the vehicle on the road, Q representing the air resistance coefficient, a representing the positive frontal area of the vehicle, and V representing the vehicle speed. The data can be obtained by a sensor of the vehicle, the ramp angle alpha of the vehicle can be calculated in real time according to the formula (3), the acceleration a can be obtained through the change of the vehicle speed, and the pressure of the human body on the seat can be calculated by substituting the ramp angle alpha and the acceleration a into the formula (2). Further, the human body gravity of the driver and the passenger can be obtained according to the weight of the driver and the passenger.
Further, according to an embodiment of the present invention, the adjusting of the seat up and down according to the ratio between the human body pressure and the human body gravity comprises: when the vehicle is in an uphill driving state, the seat is adjusted downwards according to the ratio; when the vehicle is in a downhill driving state, the seat is adjusted upwards according to the ratio.
That is, when the vehicle is in an uphill state, the driver and the passengers are in an overweight state, the pressure value of the seat is increased, and the seat can be adjusted downwards according to the ratio of the human body pressure to the human body gravity so as to reduce the overweight feeling of the human body; when the vehicle is in a downhill state, a driver and passengers are in a weightless state, the pressure value of the seat is reduced, the seat can be adjusted upwards according to the ratio of the human body pressure to the human body gravity, the fitting degree of the human body stress surface and the seat is increased, and the weightlessness feeling of a human body is reduced.
For example, the seat can be adjusted upwards or downwards within the range of 0-50mm, and when the vehicle is in an uphill driving state, the seat can be adjusted downwards according to the ratio F/G between the human body pressure F and the human body gravity G: when F/G =1.0-1.1, the seat can be adjusted down by 0-10mm; when F/G =1.1-1.2, the seat can be adjusted down by 10-20mm; when F/G =1.2-1.3, the seat may be adjusted down 20-30mm; when F/G =1.3-1.4, the seat may be adjusted downward by 30-50mm. When the vehicle is in a downhill driving state, the seat is correspondingly adjusted upwards according to the ratio F/G between the human body pressure F and the human body gravity G, and the details are not repeated.
According to an embodiment of the present invention, the seat adjusting method further includes: and controlling the heights of the side waist clamping device, the backrest bulging device and the seat to return to the initial state when the vehicle is detected to be in the horizontal driving state for a preset time.
Specifically, by detecting the vehicle speed and the running state of the vehicle by various sensors on the vehicle, it is possible to restore the heights of the side lumbar clamping device, the backrest rising device, and the seat to the initial states when the vehicle continues to move horizontally at a uniform speed for a preset time. The position of the seat in the initial state can be a self-approved comfortable position in which the driver and the passenger can interactively adjust the seat when sitting, and can also be an optimal seat position which is set by a vehicle off-line factory and accords with ergonomics.
