If these latter conditions are not fulfilled, the red warning signal specified in paragraph 5. This paragraph does not apply to vehicles where the prescribed deceleration values can be reached without the use of electrical energy. The calibration of the surface has to be carried out at least once a year with a representative vehicle to verify the stability of R.

ECE R13H 第1版 第4次修订_百度文库

Vehicle type according to Regulation No H approval: Brake applications where modulation only occurs once during the stop shall not be considered to meet this definition.

As from r1h3 official date of entry into force of Supplement 9 to the original version of this Regulation, Contracting Parties applying this Regulation: When checking vehicles for conformity of production, the Technical Services should follow the same procedures as for type-approval.

Setting of pressure valve: Determine lateral velocity by integrating corrected, filtered and zeroed lateral acceleration data. The application for approval of a vehicle type with regard to braking shall be submitted by the vehicle manufacturer or by his duly accredited representative. The pedal is released when the second axle locks, or when the pedal force reaches l kN, or 0,1 seconds after the first lockup, whichever occurs first.

In this case, the requirement on the state of charge of the batteries is not eece. It shall be capable of generating the inertia required by paragraph 3.

ECE Regulation 90 – Wikipedia

The service braking system shall make it possible to control the movement of the vehicle and to halt it safely, speedily and effectively, whatever its speed and load, on any up or down gradient. This information shall be subject to discussion r133h agreement between the Technical Service and the vehicle manufacturer.

If it is demonstrated that for practical reasons the three values defined above cannot be obtained, then the minimum time t min may be utilised. FT and aT are threshold force and threshold deceleration as shown in Figure 1.


The systems providing service, secondary and parking braking may have common components so long as they fulfil the following conditions: The service braking system shall not be adversely affected by the disengagement of the motor s or by the gear ratio used.

Verify that the ESC malfunction indicator again illuminates to signal a malfunction and remains illuminated as long as the engine is running or until the r133h is corrected. A vehicle equipped with a category 1 anti-lock system shall meet all the requirements of this annex. Accuracy of pedal force and disc temperature measurements shall be as follows: Application for approval 4. Additional material and analysis data of paragraph 3. Identification code of brake discs covered by r13g braking ecs approval … 2.

The maximum time permitted between each test run r13g five minutes.

ECE Regulation 90

The manufacturer shall, by the use of this identification, affirm that the equipment ec conforms to the corresponding document. A vehicle equipped with a category 3 anti-lock system shall meet all the requirements of this annex, except those of paragraphs 5. Maximum mass of vehicle: That is computer controlled with the computer using a closed-loop algorithm to limit vehicle oversteer and to limit vehicle understeer based on the evaluation of actual vehicle behaviour in comparison with a determination of vehicle behaviour demanded by the driver.

Alternatively, for vehicles with battery powered electric traction only, the state of charge may be adjusted by running the vehicle. Provisions relating to energy sources and energy storage devices energy accumulators.

During the type-approval testing of a vehicle, the technical service shall verify conformity with the requirements contained in the present annex, by carrying out the following tests:. This level shall be r13b least such as to ensure the ecf prescribed for service braking when the vehicle is laden. However, a device comprising a red tell-tale signal lighting up when the fluid in the reservoir is below a certain level specified by the exe is permitted. This requirement is deemed to be satisfied if the batteries are at one of the state of charge conditions as listed in paragraph 1.

Ecs steering r13 programmed to execute the required d13h pattern shall be used in paragraphs 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.

The control of the service braking system shall be independent of the control of the parking braking system. The normal frequency of these verifications shall be once every two years.


From the second phase, the energy consumption corresponding to the initial brake application may be taken into account, by subtracting one full brake application from the four full applications prescribed in paragraph 5.

However, systems or functions, which use the braking system as the means of achieving a higher level objective, are subject to Annex 8 only insofar as they have a direct effect on the braking system.

A specified failure or defect shall be signalled to the driver by the above-mentioned warning ee s not later than on actuation of the relevant braking control; 5.

EUR-Lex Access to European Union law

An outline description of the pertinent inputs to the computer that control ESC system hardware and how they are used to limit vehicle understeer. The vehicle shall be laden, the r13u of its mass among the axles being that stated by the manufacturer; where provision is made r13hh several arrangements of the load on the axles the distribution of the maximum mass among the axles shall be such that the mass on each axle is proportional to the maximum permissible mass for each axle.

The temperature of the cooling air shall be the ambient temperature.

Re-perform the manoeuvre described in paragraph 5. The parking braking system shall be capable of holding the laden vehicle stationary on a 20 per cent up or down gradient. Type-0 test with engine connected, service braking in accordance with paragraph 2.

This document is an excerpt from the EUR-Lex website. The manufacturer shall notify r13n Technical Service of the required brake pedal input at the time of submission of the application for type-approval.

For each of these valid tests the vehicle deceleration shall be plotted as a function of the recorded brake pedal force. A vehicle approved to this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraph 5 above.

To replicate a level of state of charge in the batteries for comparative tests, such as those of paragraph 1. Considerations for additional phaseless digital filtering include selection of pass bands and stop bands and the attenuation and allowable ripple in each; and correction of filter phase lags.
