Embodiment

[0062] Such as figure 1 As shown, a car driving seat travel setting method suitable for the physiological characteristics of the Chinese human body mainly involves the analysis of the Chinese human body characteristics and the creation of the human body model, the simulation calculation of the driving posture, and the setting of the driving seat travel. The steps are as follows:

[0063] Considering the development of vehicle market positioning to determine the vehicle width (W103), usually set the Y coordinate of the driver's seat reference point (SgRP-1) to 20% of the vehicle width, and fine-tune the passenger compartment space and parts layout.

[0064] Consider the vehicle height (H101) and ground clearance (H156) of the development vehicle to determine the front and rear wheel center coordinates in the vehicle coordinate system, and determine the tread point coordinates according to the X-direction distance (L113) from the front wheel center to the tread point, which is a ...

Abstract

The invention discloses an automobile driving seat stroke setting method suitable for Chinese human physiological characteristics. The method comprises the following steps: setting a Y coordinate, a wheel center coordinate and a driver stepping point (BOF) coordinate of a driver seat reference point (SgRP-1) in a whole automobile coordinate system by combining development automobile market positioning and existing platform resources; by comprehensively analyzing human physiological characteristics in China, creating a human body model containing all stature categories in a target user group on the basis of Ramsis software; and building a whole vehicle driving environment model, constraining a human body according to an actual driving state, carrying out simulation calculation on driving postures of various stature categories, generating coordinates of driver seat reference points (SgRP-1) according to a simulation result, carrying out fitting processing on all the generated seat reference points (SgRP-1), and creating a seat stroke by taking a fitting straight line as a benchmark. According to the method, the physiological characteristics of domestic target user groups are considered, the driving seat travel is reasonably set, and the driving comfort and operation convenience are improved.

Description

technical field [0001] The invention belongs to the field of automobile general layout design, and particularly relates to a method for setting a driver's seat stroke suitable for Chinese human physiological characteristics, which is mainly used for setting the driver's seat stroke in the vehicle concept design stage. Background technique [0002] With the continuous development of society, the demand for automobiles is transitioning to the demand for improvement, and consumers have put forward higher requirements for the comfort of automobile products. In the process of driving, the driver's sitting posture is not comfortable, and it is easy to produce psychological and physical fatigue reactions, which may affect driving safety in severe cases. How to ensure that the driver obtains a reasonable and comfortable posture during driving has become an important research topic in the vehicle development process. [0003] Patent Document 1 (CN 110539824 A) discloses a method and...
