AI Technical Summary

Technical Problem

During the automatic adjustment of a car's electric seats, excessive adjustment of the front seats may compress the rear passengers, affecting their riding experience and safety.

Method used

By installing pressure sensors in the rear seats of the driver and front passenger, pressure signals are acquired and it is determined whether the pressure exceeds the threshold. A seat convergence command is then issued to adjust the seat to avoid squeezing the rear passengers. The seat's sensor-based anti-pinch function is realized using the vehicle body controller.

Benefits of technology

When there are passengers in the rear seats, the range of seat adjustment should be limited to ensure space for rear passengers, prevent squeezing injuries, and improve the riding experience and safety.

Description

TECHNICAL FIELD

[0001] The present application belongs to the field of automatic control of automobiles, and particularly relates to an induction type anti-pinch method and system for an electric seat of an automobile. BACKGROUND

[0002] Automobile seats are not only a simple component of the vehicle, but also a key element of the driving and riding experience. They are carefully designed to provide the driver with a convenient, comfortable, and highly safe driving position. For the driver, the appropriate position of the seat not only affects the control accuracy of key operating components such as the steering wheel, accelerator, and brake, but also directly relates to the safety of driving. At the same time, the comfort of the seat directly affects the driving experience of the driver. A comfortable seat can significantly reduce the driver's fatigue during long driving, thereby ensuring driving safety.

[0003] The function of seat adjustment further improves the comfort of riding. By adjusting the angles of the seat in front and back, high and low, and inclination, the driver and passenger can adjust to the most comfortable position according to their height, body shape, and preferences. This personalized adjustment not only improves the comfort of riding, but also reduces the fatigue caused by maintaining the same posture for a long time. At the same time, the adjustment of the seat can also adapt to different driving and riding needs, such as adjusting the seat to a more comfortable angle during long trips to reduce fatigue, and adjusting the seat to a more compact angle during intense driving to better control the vehicle.

[0004] Automobile electric seats refer to seats that are powered by electric motors to drive transmission devices and actuators, thereby adjusting various positions of the seats to make the driver or passenger comfortable. The working principle of electric seats is mainly to drive the gear mechanism by the electric motor to realize the longitudinal and lateral movement of the seat and the angle adjustment of the backrest. Electric seats can be divided into electric control adjustment systems and seats without electric control adjustment systems. According to the adjustment method, they can be divided into manual adjustment and power adjustment. According to the different power sources, power adjustment can be divided into vacuum type, hydraulic type, and electric type.

[0005] Automobile seats are the main safety components of automobiles, and the comfort of the seat directly affects the safety of driving. Manual seat operation is complex, and the mechanism is easy to jam during adjustment, which directly affects the safety of driving. Electric seats can improve the shortcomings of manual seats and have the advantages of one-key operation: simple, convenient, fast, safe, stable, etc., which is the best choice to improve the safety and comfort of people during driving.

[0006] By operating the electric seat switch, the seat and backrest can be adjusted to the optimal position, so that the driver can obtain the best view and easily operate the steering wheel, accelerator pedal, brake pedal and gear lever. However, when the front seat is automatically adjusted, the rear passengers are often ignored. If the front seat is adjusted too far backward, the comfort and experience of the rear passengers will be affected, and even the rear passengers will be injured due to the squeezing. SUMMARY

[0007] The purpose of the present application is to provide an inductive anti-pinch method and system for an electric seat of an automobile, so as to solve the problem of squeezing the rear passengers by the automatic adjustment of the front electric seat during daily driving.

[0012] According to the convergence instruction, the main and vice driver seats are adjusted to the maximum threshold value when there are passengers in the rear row.

[0017] The further improvement of the present application is that when the main and vice driver passengers trigger the convenient entry and exit function of the electric seat, the vehicle controller judges whether the convenient entry and exit instruction exceeds the threshold value, and the vehicle body controller receives the convenient entry and exit instruction to adjust the seat convergence.

[0018] The further improvement of the present application is that when the main and vice driver triggers the manual adjustment function of the electric seat, the vehicle controller judges whether the manual adjustment instruction is over the threshold value, and the body controller receives the manual adjustment instruction to adjust the seat to converge.

[0019] In the second aspect, the present application further provides an inductive anti-pinch system of an electric seat of an automobile, comprising the following modules:

[0023] In the third aspect, the present application further provides an electronic device comprising a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the anti-pinch method of the electric seat of the automobile when executing the computer program.

[0024] In the fourth aspect, the present application further provides a storage medium having a computer program stored thereon, and the computer program implements the steps of the anti-pinch method of the electric seat of the automobile when executed by a processor.

[0025] Compared with the prior art, the present application has the following beneficial effects:

[0039] The vehicle body controller receives the convergence instruction, including the position memory instruction, the convenient access instruction and the manual adjustment instruction;

[0040] When the main and vice driver passengers trigger the position memory function of the electric seat, the vehicle controller judges whether the position memory instruction exceeds the threshold value, and the vehicle body controller responds to the position memory instruction to adjust the seat convergence;

[0041] When the main and vice driver passengers trigger the convenient access function of the electric seat, the vehicle controller judges whether the convenient access instruction exceeds the threshold value, and the vehicle body controller responds to the convenient access instruction to adjust the seat convergence;

[0042] When the main passenger triggers the manual adjustment function of the electric seat, the vehicle controller judges whether the manual adjustment instruction exceeds the threshold, and the body controller responds to the manual adjustment instruction to adjust the seat to converge.

[0043] As shown in Figure 2 An inductive anti-pinch system of an automobile electric seat, comprising the following modules:

[0044] A pressure sensing module is used to obtain the pressure signal output by the rear seat pressure sensor of the main and deputy driver seat during adjustment, and to judge whether the pressure signal exceeds the threshold;

[0048] The inductive anti-pinch function of the automobile electric seat is designed to improve the safety and riding experience of passengers, and the signal priority of the pressure sensing device arranged on the rear seat cushion is greater than that of the front seat adjustment.

When the pressure signal exceeds the threshold, the body controller interferes with the convergence of the front seat adjustment. After issuing the seat adjustment signal, the vehicle controller judges whether there is a signal input from the pressure sensing device of the rear seat cushion. If there is no, the body controller does not interfere with the front seat adjustment. The method of the present application can converge the amplitude of the rear seat adjustment in the presence of passengers in the rear seat, ensure the space of the rear passengers, and avoid the situation of rear passengers being squeezed and injured.
