Trade name or mark of the vehicle, if available: Where applicable, a yellow warning signal indicating an electrically detected defect within the vehicle braking equipment, which is not indicated by the red warning signal described in paragraph 5.

It shall be possible to easily assess this wear on service brake linings from the outside or underside of the vehicle, without the removal of the wheels, by the provision of appropriate inspection holes or by some other means. An outline description of r3h pertinent inputs to the computer that control ESC system hardware and how they are used to limit vehicle understeer.

Setting of pressure valve: In the case of the latter Regulation the corrected absorption coefficient is 1,30 m —1.

ECE Regulation 90

This calculation shall be made for each axle having at least one directly controlled wheel. Zero lateral velocity at the BOS point.

At one-half the sampling rate i. The Vehicle Stability Function shall be added to the simulation model by means of:. A simulator test report shall be produced, a model of which is defined in Appendix 3 to this annex, and a copy attached to the vehicle approval report. Braking tests and performance of braking systems Appendix — Procedure for monitoring the exe of battery charge 4. The manufacturer shall, by the use of this identification, affirm that the equipment supplied conforms to the corresponding ede.

If the wheel-lock sequence test indicates that the rear wheels lock before the front wheels, then dce vehicle:. This allows complex systems to automatically change their objectives with a priority which depends on the sensed circumstances.

The validity of the applied modelling and simulation tool shall r133h verified by means of comparisons with practical vehicle tests.

The power supply generator and battery of the motor vehicle shall have a sufficient capacity to provide the current for an electric braking system. In order to execute the necessary filtering of signals, low-pass filters with order 4 or higher shall be employed. Total normal static reaction of road surface on all wheels of power-driven vehicle.

It shall be demonstrated to the satisfaction of the Technical Service that the BAS activates under the conditions efe by the manufacturer in accordance with paragraph Special additional requirements for service braking systems with electric control transmission: The warning signal s e13h above shall light up when the electrical equipment of the vehicle and the braking system is energised. There shall be a clear correspondence between these transmission links and the signals carried between units.

For vehicles equipped with an electric regenerative braking system of category B, the condition of the vehicle batteries at the start of the test, shall be such that the braking force contribution provided by the electric regenerative 1r3h system does not exceed the minimum guaranteed by the system design.

The steering wheel velocity data is then filtered with a moving 0,1 second running average filter. In order to avoid uncorrectable aliasing errors, the analogue signals shall be appropriately filtered before sampling and digitising.

The steering amplitude for the initial run of each series is 1,5 A, where A is the steering wheel angle determined in paragraph 5. The vehicle stability function shall be demonstrated by the vehicle manufacturer to the Type Exe Authority or Technical Service by simulating the dynamic manoeuvres of paragraph 5.

In this case, the requirement on the state of charge of the batteries is not applicable. Vehicles r13hh with an electrical regenerative braking system of category B may have their batteries re-charged or replaced by a charged set, in order to complete the recovery procedure. Communication Appendix — List of vehicle data for the purpose of Regulation No 90 approvals 2.

The brake pedal force F ABS is the minimum pedal force that has to be applied for a given vehicle in order to achieve maximum deceleration which indicates that ABS is fully cycling. Pedal force is applied and controlled by a skilled driver or by a mechanical brake pedal actuator.

If a Contracting Party to the Agreement which applies this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation by means of a copy of the communication form conforming to the model in Annex 1 to this Regulation.

Accuracy, operating ranges, filtering techniques, data processing and other requirements are described in ISO Standard The vehicle is subjected to two series of test runs using a ecf pattern of a sine wave at 0,7 Hz frequency with a ms delay beginning at the second peak amplitude as shown in Figure 2 the Sine with Dwell tests.

Priorities of signals on multiplexed data paths shall be stated, wherever priority may be an issue affecting performance or safety as far as this Regulation is concerned.

In case of a failure, the driver shall be warned for example by warning signal or message display. In order to activate BAS the brake pedal shall be applied as specified by the car manufacturer. Preparation of analogue signals includes consideration of filter amplitude attenuation and sampling rate to avoid aliasing errors, and filter phase lags and time delays. Vehicles fitted with an electric regenerative braking system of category A.

The type of fluid to be used in hydraulic transmission braking systems shall be identified by the symbol in accordance with Figure 1 or 2 of Standard ISO Braking tests which the vehicles submitted for approval are required to undergo, and the braking performance required, are described in Annex 3 to this Regulation.

An alternative measuring method may be allowed for type approval testing, provided it demonstrates at least an equivalent level of precision as the double integration method. The driver shall apply the brake pedal quickly according to Figure 2, simulating emergency braking so that BAS is activated and ABS is fully cycling.

After the braking equipment is first energised and the signal has indicated that, following the procedures detailed in paragraph 5. Alternative measuring methods to those referred to in paragraph 2.

Where the braking power is derived from or assisted by a source of energy independent of the driver, the reserve of energy in the system is likewise part of the transmission. The driver shall apply the brake pedal quickly according to Figure 2, simulating emergency braking so that BAS is activated and ABS is fully cycling.

Vehicles on which the braking equipment requires the use of stored energy provided by hydraulic fluid under pressure shall be equipped with energy storage devices energy accumulators of a capacity meeting the requirements of paragraph 1. To eliminate the effects of differential brake temperatures it is recommended that z AL be determined prior to the determination of k. Compliance with this requirement is demonstrated if the provisions of paragraphs 3.

The absolute value of the six A values calculated is averaged and rounded to the nearest 0,1 degrees to produce the final quantity, A, used below. The order of the filters used and their pass band shall be chosen according to both the required flatness in the relevant frequency range and the sampling rate.

Use of the dynamic stability simulation. Drum brake type e.
