Foreword

This document was drafted in accordance with the rules of GB/T 1.1-2020 Directives for Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents. This document serves as a replacement of GB/T 17346-1998 Passenger Cars - Lateral Spacing of Foot Controls. In comparison with GB/T 17346-1998, apart from structural adjustments and editorial modifications, the main technical changes are as follows:

a) The first chapter Scope is modified (see Chapter 1; Chapter 1 of Version 1998);

b) The terms and definitions of vehicle coordinate system, Z-plane, Y-axis direction, pedal centerline, center line of driver, brake pedal reference point, and clutch pedal reference point are added (see 3.1, 3.3, 3.4, 3.11, 3.12,

c) Some terms and definitions are modified (see 3.2, 3.5, 3.6, 3.7, 3.8,

3.9 and 3.10; 3.5, 3.1, 3.2, 3.3, 3.7,

3.8 of Version 1998);

d) The term and definition of "horizontal plane" is deleted (see

3.4 of Version 1998);

e) The content of "arrangement of pedals" is deleted (see

4.1 of Version 1998);

f) The dimension categories of "Y-plane projection view" and "pedal lateral distance at specified position" are added (see

g) The dimension category of "P-plane projection view" is modified (see 4.2.1.1, 4.2.1.2, 4.2.1.4,

4.2.1.6 and 4.2.1.7; 4.2,

4.4 of Version 1998);

1 Scope

GB/T 17346-2023 is the Chinese national standard on test methods of automobile pedal position dimensions, in the field of road vehicles engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 17 March 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2023. Classification: ICS 43.040.50, CCS T23. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the dimension categories and measurement methods of automobile pedal position dimensions. This document is applicable to Category-M and Category-N vehicles, and other vehicles may take this as a reference. This document does not apply to pedals other than accelerator pedals, brake pedals and clutch pedals.

3 Terms and Definitions

What is defined in GB/T 4782-2001, GB/T 12673-2019 and GB/T 29120, and the following terms and definitions are applicable to this document.

3.1 vehicle coordinate system Vehicle coordinate system consists of three interrelated vertical and orthogonal planes, which are used to determine the positional relationship among planes, axes and points. NOTE: see Figure 1. [source: GB/T 12673-2019, 3.1] Center line of driver refers to the Y-coordinate plane of R point where the driver sits.

3.13 brake pedal reference point Brake pedal reference point refers to the midpoint of the brake pedal centerline or the point at which the brake pedal surface centerline is 200 mm from the heel of shoe on the Y-axis direction view. NOTE 1: for suspended brake pedals, the brake pedal reference point is the midpoint of the brake pedal centerline, or the point specified by the manufacturer. NOTE 2: for floor-standing brake pedals, the brake pedal reference point is the point at which the brake pedal surface centerline is 200 mm from the heel of shoe on the Y-axis direction view, or the point specified by the manufacturer.

3.14 clutch pedal reference point Clutch pedal reference point refers to the midpoint of the clutch pedal centerline or the point at which the clutch pedal surface centerline is 200 mm from the heel of shoe on the Y-axis direction view. NOTE 1: for suspended clutch pedals, the clutch pedal reference point is the midpoint of the clutch pedal centerline, or the point specified by the manufacturer. NOTE 2: for floor-standing clutch pedals, the clutch pedal reference point is the point at which the clutch pedal surface centerline is 200 mm from the heel of shoe on the Y-axis direction view, or the point specified by the manufacturer.
