Furthermore, laden vehicles equipped with anti-lock systems of category 1 shall, under the conditions of paragraph 5. The same Contracting Party shall not assign the same number to the same vehicle type equipped with another type of braking equipment, or to another vehicle type.

Verify that the ESC malfunction indicator illuminates in accordance with paragraph 3. For a vehicle with electrically actuated service brakes powered from traction batteries or an auxiliary battery which receive s energy only from an independent external charging system, these batteries shall, during braking performance testing, be at an average of not more than 5 per cent above that state of charge at which the brake failure warning prescribed in paragraph 5.

The lateral acceleration data at the vehicle ee of gravity is determined by removing the effects caused by vehicle body roll and by correcting for sensor placement via the use of coordinate transformation.

In the case of an optical warning, the yellow warning signal specified in paragraph 5. Test requirements for vehicles fitted with anti-lock systems Appendix 1 — Symbols and definitions Appendix 2 — Utilisation regularions adhesion Appendix 3 — Performance on differing adhesion surfaces Appendix 4 — Method of selection regulationz the low adhesion surface 7.

The documentation shall be supported, by an analysis which shows, in overall terms, how the system will behave on the occurrence of any one of those specified faults which will have a bearing on vehicle control performance or safety. In the case of vehicles equipped with electric regenerative braking systems of category B, the braking input from other sources of braking, may be suitably phased to allow the electric regenerative braking system alone to be applied, provided that both the following conditions are met: The maximum time permitted between each test run is five minutes.

Using the relationship between front and rear brake line pressure determined in paragraph 3 i above and the dynamic tyre rolling radius, calculate the braking force at each axle as a function of front brake line pressure.

This information shall be made freely available, e. In the event of a failure in the energy source, whilst the vehicle is stationary and the parking braking system applied, the energy in the reservoir shall be sufficient to actuate the lights even when the brakes are applied. Shall extinguish at the next ignition cycle after the malfunction has been corrected in accordance with paragraph 5. Calculate the braking rate of the vehicle as a function of the front brake line pressure using the following equation:.

Characteristics of braking systems 5. The average temperature of the brakes shall be in accordance with paragraph 1.

EUR-Lex – X(01) – EN – EUR-Lex

The combination performance shall be verified by calculations referring to the maximum braking performance actually achieved by the motor vehicle alone laden during the Type-0 test with the engine disconnected, using the following formula no practical tests with a coupled unbraked trailer are required:.

The steering amplitude for the initial run of regulaations series is 1,5 A, where A is the steering wheel angle determined in paragraph 5. When an emergency condition has been sensed, at least regu,ations a very fast application of the pedal, the BAS system shall raise the pressure to deliver the maximum achievable braking rate or cause full cycling of the ABS.

The utilisation of adhesion by the anti-lock system shall be checked on complete vehicles equipped with anti-lock systems of categories 1 or 2. Vehicles on which the braking equipment requires the use regultions stored energy provided by hydraulic fluid under pressure shall be equipped with energy storage devices energy accumulators rgeulations a capacity meeting the requirements of paragraph 1. The parking braking system shall make it possible to hold the vehicle stationary on an up regulatoons down gradient even in the absence of the driver, the working parts being then held in the locked position by a purely mechanical device.

The equipment consists of the control, the transmission, and the brake proper. If the vehicle conforms to a vehicle type approved under one or more other Regulations, annexed to the Agreement, in the country which has granted approval under this Regulation, the symbol prescribed in paragraph 4. The purpose of this test is to ensure that lockup of both front wheels occurs at a lower deceleration rate than the lockup of both rear wheels reguations tested on road surfaces on which wheel lockup occurs at braking rates between 0,15 and 0,8.

If such systems are provided, they shall not be deactivated during type approval testing of the braking system. The test vehicle is driven around a circle 30 meters in diameter at a speed that produces a lateral acceleration of approximately 0,5 to 0,6 g for three clockwise laps followed by three anticlockwise laps. This document is an excerpt from the EUR-Lex website. Assessment of the wear condition of the friction surfaces of brake discs or drums may only be performed by direct measurement of the actual component or examination of any brake disc or drum wear indicators, which may necessitate some level of disassembly.

Where use is made of energy other than the muscular energy of the driver, there need not be more than one source of such energy hydraulic pump, air compressor, etc.

Calculate the adhesion utilised at each axle as a function of braking rate using the following formulae:. Dynamic stability simulation tool and its validation. For comparison, a later Type-0 test with cold brakes shall be repeated from this same speed and with a similar electric regenerative braking contribution, as set by an appropriate state of battery charge, as was available during the hot performance test.

This energy may be the muscular energy of the driver, or energy from another source controlled by the regjlations, or a combination of these various kinds of energy.

This warning device shall be directly and permanently connected to the circuit. An outline schematic showing these units in combination, shall be provided with both the equipment distribution and the interconnections made clear.

Torque wheel test procedure. Regulztions value for time at the BOS is interpolated. They may include mechanical, electro-pneumatic or electro-hydraulic elements. This condition shall be met by means of devices which can easily be actuated when the vehicle is stationary, or by automatic means. These rebulations surfaces shall satisfy the conditions prescribed in paragraph 5. The symbol and the marking shall be affixed in a visible position in indelible form within mm of the filling ports of the fluid reservoirs; additional information may be provided by the manufacturer.

In the case of a vehicle equipped with an anti-lock system of category 3, the value of z AL will be measured on each axle which has at least one directly controlled wheel. Names and addresses of the Technical Services conducting approval tests, and of Type G13 Authorities The force exerted on the braking control device shall not exceed the specified values. Make and type of brake linings, discs and drums: When the braking tests of regylations 1.

Height of centre of gravity specified by the manufacturer and agreed by the Technical Service conducting the approval test.
