Описание (английский):

This International Standard specifies tests and measurement methods for solo motorcycles (defined in ISO 3833) equipped with one or more antilock, and one or more independent, braking systems. It sets out procedures for the following types of straight-line braking tests: utilization-of-adhesion test; wheel-lock check test; tests with ABS failed; complementary tests that could assist in the assessment and development of braking systems.

Overview

ISO 12364:2001 - Two-wheeled motorcycles - Antilock braking systems (ABS) - Tests and measurement methods defines uniform test procedures and measurement methods for evaluating antilock braking systems (ABS) on solo motorcycles (L3 category as per ISO 3833). The standard focuses on straight-line braking performance and sets out repeatable procedures for determining adhesion utilization, wheel-lock behavior, ABS-failure responses and complementary tests to aid development and assessment.

Keywords: ISO 12364:2001, motorcycle ABS tests, antilock braking systems, adhesion utilization, wheel-lock check, braking test methods

Key topics and technical requirements

Scope and test types

Utilization-of-adhesion test (determines how well ABS uses available grip)
Wheel-lock check test (verifies wheel-lock behavior, unladen)
Tests with ABS failed (electronically controlled systems)
Complementary tests for development and assessment

Test site and environmental limits

Two reference surfaces: coefficient of adhesion ≤ 0.45 and ≥ 0.80
Surface gradient ≤ 1 %; water depth on wetted surfaces ≤ 3 mm
Average wind speed ≤ 5 m/s
Test lane of sufficient length/width and flat surrounding area

Motorcycle preparation and instrumentation

Tyres inflated to manufacturer’s recommended pressures
Rider + test equipment mass minimum 85 kg; instrumentation mass should not exceed 10 % of unladen mass
Brake temperature on discs/drums should be ≤ 100 °C before each stop
ABS must be disabled for coefficient-of-adhesion determination
Required instrumentation: wheel-speed sensors, speedometer/third wheel, multi-channel recorder (bandwidth ≥ ABS cycling frequency), control force or brake-fluid pressure sensors; outriggers optional for safety

Test execution and calculations

Test speeds: typical reference 60 km/h (or 0.9·vmax for lower-speed motorcycles); ±5 km/h tolerance
Control forces applied rapidly (recommended 0.2–0.5 s to reach target); force references from ISO 8710: [200 N] hand, [350 N] foot
Adhesion utilization (e) and coefficient of adhesion (k) derived from measured braking rate
Braking rate z example: z = 0.56 / t, where t = time to decelerate from 40 km/h to 20 km/h

Reporting

Detailed test report required (speeds, forces, ambient conditions, vehicle/ABS ID, tyre data, results, deviations). Annex A provides an example report format.

Applications and users

Who uses ISO 12364:2001

Motorcycle manufacturers and ABS system suppliers for validation and design
Test laboratories and certification bodies performing braking performance assessments
Regulatory and homologation authorities referencing standardized test methods
R&D teams optimizing ABS control algorithms and vehicle braking balance

Practical value

Ensures repeatable, comparable ABS performance data across sites and manufacturers
Supports safety validation, compliance testing and development benchmarking
Helps quantify how effectively ABS exploits road adhesion under controlled conditions
