Method and device for evaluating comfort of automotive seat

Abstract

The invention provides a method and a device for evaluating comfort of automotive seats. The method comprises the following steps: mounting a to-be-evaluated automotive seat on a driving simulation platform, and placing a pressure sensor on the to-be-evaluated automotive seat; acquiring body pressure distribution data of an evaluator, and carrying out subjectively evaluating the comfort of the automotive seat by the evaluator; repeatedly carrying out the steps to measure automotive seat comfort evaluation results of different evaluators and different types of automotive seats, and establishing an automotive seat comfort database; establishing a seat comfort evaluation model by virtue of a related mathematical method according to the automotive seat comfort database; measuring the body pressure distribution data of the evaluator of a new seat, and acquiring a seat comfort evaluation result of the new seat according to the seat comfort evaluation model. The device comprises a sensor placing module, an automotive seat adjusting module, an objective evolution module, a subjective evolution module and a comfort evolution module. According to the method and the device, the comfort evaluation workflow of the seats is clear, the operation is simple, and the evolution result is accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of automobile comfort evaluation, in particular to a method and device for evaluating the comfort of automobile seats. Background technique [0002] With the increasing popularity of automobile consumption and people's higher and higher requirements for ride comfort, the issue of car ride comfort is becoming more and more important. Ride comfort can effectively improve the ride experience of the occupants, so that the driver can Obtaining a reasonable and comfortable driving posture can effectively relieve the driver's fatigue, and has gradually become one of the concerns of major vehicle manufacturers and parts companies in the international automobile industry. Among them, car seats and various control devices, such as, The design of the steering wheel and pedals of the cab determines the driver's posture comfort. Therefore, the ride comfort mainly refers to the comfort of the car seat. [0003] After the...

Problems solved by technology

[0007] Domestic self-owned brand enterprises generally use the body pressure distribution evaluation method when developing new car seat products, and use European and American evaluation methods and standards to measure body pressure distribution data. However, seat comfort research in Europe and the United States is based on European and American populations, in view of the differences in race, lifestyle, eating habits, etc., therefore, it is obviously difficult to apply European and American evaluation methods and standards directly to East Asian populations. If they are directly applied, the reliability of seat comfort evaluation will be low , can not meet the requirements of East Asian people for seat comfort
