3Terms and Definitions.
GB T12673 and the following terms and definitions apply to this document.
Vehicle coordinate system
It consists of three perpendicular orthogonal planes that are related to each other and are used to determine the position relationship between planes, axes, and points.
Note: See Figure 1.
Driver Hand-Reach CapabilityIn a simulated driving environment, the driver holds the steering wheel with one hand, presses the accelerator pedal with his right foot, and reaches the maximum capacity of the other hand. Note: Maximum reach for 95% of the driver population is described.
Basic Reach Task
Tasks operated by the driver in a forward-facing one-finger direction.
Note: The corrected values of the hand reach and interface for other reach tasks are shown in Table 1
Hand-reach envelope
Geometric depiction of the driver's hand reach capacity for a specific proportion of the driver population and the type of torso restraint.
Note 1: The contour of the hand reach interface refers to the geometric center of the surface of the manipulator.
Note 2: The types of torso restraints include three-point harness torso forward and three-point harness torso non-forward.
r-point
The design H-point location set by the manufacturer, specifically designated as the R-point or SRP, satisfies all of the following requirements:
a) is the basic reference point used to establish the occupant adjustment tool and size;
b) Simulate the central position of the human torso and thighs;
c has coordinates established relative to the structure of the vehicle designed;
The h-point at the rearmost of each designated seating position or the normal driving and seating position specified by the manufacturer is established, which takes into account all adjustment states of the seat, including horizontal, vertical, and recline, but excludes seat movement for non-normal driving and riding purposes.

accelerator heel point;ahp
When the ankle angle is 87", the shoe is placed on the uncompressed accelerator pedal plane, the intersection of the heel and the pressed floor covering.
Note: If the intersection of the footwear with the side supports does not cause an offset of the AHP and BOFRP, the transverse position (Y-band) is the same as the BOFRP [**GB T12673-2019,3.].3.10]
Center plane of occupant
c po the y-coordinate plane of each specified ride location r point.
Note: For single seats, it generally refers to the seat center surface, and for bench seats, the occupant center surface is specified by the manufacturer.

4 General Requirements.
4.1. Each stretching task should be completed in the corresponding hand stretching interface, and the verification process is shown in Appendix C42. The hand extension and interface corresponding to the basic extension task should be drawn according to Appendix D, and the example of the hand extension and interface is shown in Figure 4
Figure 4 An example of a hand and interface.
4.3 Except for the basic extension task, the hand extension and interface of other reach tasks should be corrected according to the correction values in Table 1, and the corresponding hand extension and interface of the basic reach task should be translated in the +x direction to the corresponding correction values in Table 1.

Verification process.
Determine the reference origin.
Position the reference origin at the vehicle seat r-point.
Determine the datum plane.
According to a set of orthogonal datum planes, the hand extension and interface are positioned in the vehicle, and this orthogonal datum plane is: the x datum plane of the r point is parallel to the y datum plane and the plane of the r point is parallel to the z datum plane of the r point.
c.3. Select the hand to use and **.
Clearly describe the dimensions of the geometry of the vehicle seat configuration and calculate 3The value of the composite factor g defined in 8. Based on the value of the composite factor g, the type of torso restraint, and the ratio of mixed sexes, the hand-and-hand reach suitable for the vehicle and the specified driver group is selected from Appendix D.
C4 determines whether the control part is within reach.
Method 1: Follow the steps below to draw the left side of the C PO and the right hand extension interface of the C PO respectively. a) Based on the reference origin, locate the coordinate points with a horizontal azimuth angle of 30, a vertical azimuth angle of 0, a radius of hand extension and a corresponding value of **, and locate the coordinate points when the vertical azimuth angle is -15 ° 15 ° and 30 and 4560 along the vertical direction up and down: 6i According to the above steps, locate the coordinate points when the horizontal azimuth angle is 45 ° 60 ° 75 ° 90 and the vertical azimuth angle is -15 '015304560 °;
Fit coordinate points in the same horizontal azimuth to a straight line, fit the topmost point in the z-direction to a straight line, and c) in z-square
Fit a straight line to the lowest point: d) Fit all straight lines to a surface that reaches out to the interface with a deviation of no more than 1 mm from the values in the table. If the surface of the operator (in normal or stationary state) is tangent to or inside the hand interface closest to the driver, the operator is within reach.
Appendix D Normative).
Reach out**.
The Hand Reach interface describes the hand reach ability of at least 95% of the driver group (50 50, 75 25, 90 10) in the range of 7 comprehensive factors and 2 types of torso restraint (forward leaning, non-forward leaning), that is, the boundary of the hand control area that can be reached, according to Table D1 Table d42 drawn. Each hand and interface is located relative to the specified datum plane, extending vertically from -15° to 60°, horizontally bounded by c po, and from 30" to 90" on the left and right sides. Table d1 Table dThe value in 42 represents the driver's hand reach (straight-line distance from the r-point to the hand reach interface) at a certain vertical and horizontal azimuth angles. "One" means that there is no corresponding hand extension data for the location, and the data marked with underlines are fitted, not actual measurement data, and the hand reach values displayed in these districts and cities should be used with caution.
