  1. PROGRESS of BRAKING REGULATION 13.

  2. PROGRESS of BRAKING REGULATION 13. 09 Amendments Oct 1996. Annex 2 Data increase. Vehicle mass when tested + Type III test for trailer - Test Results Annex 4 - 1.5.2.1. Fade test for small trailers - continuous braking. 1.6.1/2. Type II 6% downhill test - M3,N3 with in-gear or retarder use. 1.6.3. Hot performance test - 3.75 m/s2 for M3 3.3 m/s2 N3 1.7. Type III fade test for O4 - braking snub cycles 2.1.2. Service braking un-braked trailer - 5.4 m/s2 for M1 2.3.6. Dynamic parking brake - 1.5 m/s2 from 30 km/h Annex 5 -Type IIa test: Endurance braking - 7% grade 6 km/h @ 30km/h Engine braking alone - 0.6 m/s2 Annex 11 Power driven vehicles and trailers - similar to a reference vehicle already approved. Using the reference vehicle and known parts, it is permitted to predict braking performance Annex 12 Trailers with overrun braking - overload protection requirement. Annex 13 4.3. ABS failure performance requirements 5.1.1.2. Energy consumed by indirectly controlled wheels - taken into account. Directly controlled wheels must remain under control. 6.1.3. Trailer ABS energy consumption - 15 s operation on stored energy. Annex 15 Dynamometer test of replacement brake linings Dyno capacity sufficient to meet Annex 4 Types I, II and III tests and Type III test added.

  3. PROGRESS of BRAKING REGULATION 13. Supplement 1 - Jan 1997 Main body of the Regulation. Electric Vehicles - Category A: Independent braking system Category B: Part of the Service braking system. Annex 4 Tests with Electric Vehicles. 1.2.8. If wheel motors permanently connected, test like this. 1.2.9 and make a Type O test on low mu as behaviour test. 1.5.1.6 Possible to reduce heating cycle speed. 1.5.3.1.2 Cat A vehicles shall not use any separate control. 1.5.3.3 Hot test at max. speed. 2.2.6 Performance tests under faulty RGB conditions. Annex 8 Release of spring brakes - only when stored pressure allows service brakes to give secondary. Trailers must provide energy for 3 releases after uncoupling. Annex 10 3.1.4.5. EV distribution under all states-of-charge provided unless equipped with ABS. 3.1.5.1/6.1 Distribution of braking with trailers. 4.1.1. 5.1.3. 5.2.1. Annex 13 Full cycling of ABS during tests.

  4. Supplement 2 Jan 1997 REQUIREMENTS for EBS Definition of new terms: Control / Energy transmission. Data Communication. Coupling Force Control. Nominal Values. Connections to trailers Electric and pneumatic control lines ISO 11992 Standard specified. Control Line Failures Electric control line only - not yet permitted. Incompatible combinations. Faults in the lines. Trailer Parking braking signalling Via pneumatic and/or electrical control line. Compensation Across axle compensation, axle compensation and whole vehicle compensation. Coupling Force Control On the towing vehicle only Braking adjustments on both electric and pneumatic control lines Fault Warning Signals Two categories: Red and Yellow warnings. Requirements for Trailers Similar to those of the towing vehicle but fault signalling different. Automatic braking. Annex 2 Vehicle data to be provided for Reg.90 Lining Approvals Annex 4 3.1.2.2. O2 and O3 Trailer supply line 7 bar max. Pneumatic control line 0 - 6.5 bar. Annex 6 Response tests. Simulators for towing vehicle and trailers - electric line added. Annex 8 Motor vehicle warning when spring brakes start to be applied. Annex 10 Diagrams apply to both pneumatic and electrical signals, but curves need not be identical Annex 13 Trailer performance with ABS failure to be 80% of normal laden figure. Separate trailer warning signal retained. Supply line at 8 bar at start of consumption tests. PROGRESS of BRAKING REGULATION 13

  5. PROGRESS of BRAKING REGULATION 13 Supplement 3 - April 98 Regulation 13 and Regulation 13-H made equally valid for Category M1 vehicles. 2.14. Endurance Braking definitions. Annex 2 Endurance braking performance reports added. Annex 4 1.6.4. Type IIa test replaces Type II for endurance braking systems on: Long distance coaches M3 N3 vehicles to tow O4 trailers ADR vehicles 1.8.2. Type IIa tests on endurance/engine braking Annex 5 Now deals only with the braking requirements of ADR vehicles. Supplement 4 Feb 99. 5.1.4. Provisions for Periodic Technical Inspection. 5.1.4. Inspection access. 5.1.4.2. Pneumatic pressure test connections 5.1.4.5. Pneumatic data provided 5.2.1.2.5. Common components allowed in Service and Parking braking systems. Annex 10 3.1.1. Simultaneous lock-up accepted on 4WD vehicles. 3.1.4.2. Permanent 4WD vehicles - wheel locking sequence tests.

  6. PROGRESS of BRAKING REGULATION 13 Supplement 5 Dec 2000 Revision of EBS rules. ISO 11992 - 1/2/3 updated to 1998 release. Pneumatic and electric control line agreement. ISO 11992 compatibility on towing vehicles and trailers (Annex 17 tests) Single transmission energy reserve if secondary reached by muscular energy Trailer only braking allowed for stability control. EPB rules revised (now very complicated) EBS has to generate 5.8 m/s2 even with ignition off. Single temporary transmission failure - no distinguishable effect. No discharge of battery when all normal electrical loads on and engine running Warning signals revised somewhat. Other failures may use flashing brake warnings but only when stationary. Alternative to Automatic braking on electric only signalling. Simulator performance explained Annex 15 Dynamometer cooling air speed increased. Annex 16 Interpretation of ISO 11992 applications ( brakes and running gear.) Annex 17 ISO 11992 compatibility test procedure using simulators defined.

  7. PROGRESS of BRAKING REGULATION 13 Supplement 6 Jan 2002 Electric Vehicles replaced with ‘Vehicles with Electrical Regenerative Braking’ Rules and tests to be applied: Phased Braking Compensation for RGB variation Electric State of Charge. Electrically Actuated Service Brakes Over-run Braking Systems: Additions for overload protection NEW ANNEX 18: Requirements for Complex Electronic Vehicle Control Systems. Definitions - Safety Concept, Systems Units & Boundaries Documentation - 2 parts Functional description System layout and interconnections Safety concept Verification and Test

  8. New Regulation Issues to be Considered. Final WP29 acceptance of Modular Trailer Braking System rules. Global Harmonisation of rules for illuminating Stop Lamps. PTI requirements connected with brake inspection. Brake Lining Assemblies - Marking and Packaging. Towing Vehicle/Trailer Compatibility. (Disc brakes and EBS/CFC) Reg.90 Test procedures. Dyno tests and speed sensitivity tests. Longer Term Issues. Global Harmonisation. Motor Cycle Braking Tyres Safety Glass, Washers and wipers Seat Belts Headlamps Controls and Warning signals. Braking. (EVs priority) Anti-theft Devices Higher Level Automatic Control Systems. (Driver assistance systems - Government concern) Intelligent Transport Systems. (Industry/Government collaboration?) Electrical Energy Management Systems.
