Subject to the provisions of paragraph In addition, such an electrical failure in the control or break in the wiring rgeulations to the electronic control unit s and excluding the energy supply shall be signalled to the driver by flashing the red warning signal specified in paragraph 5. This condition is deemed to be satisfied if the state of charge of the batteries is in one of the following conditions:.

If this warning is given, the batteries may receive some recharge during the tests, to keep them in the required state of charge range. 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: In braking tests, and in particular in those at high speed, the general behaviour of the vehicle during regulatilns shall be checked.
However, systems or functions, which use the braking system as the means of achieving a higher level objective, eec subject to Annex 8 only insofar as they have a direct effect on the braking system. That has a means to monitor driver steering inputs; and 2. To check compliance with the requirement specified in paragraph 5. Except as provided in paragraphs 3.

The performance prescribed in paragraph 5. This procedure is applicable to vehicle batteries used for traction and regenerative braking. This requirement shall not apply to a parking brake control when it is mechanically locked in an applied position; 5.
Use of the dynamic stability simulation. The minimum performance prescribed shall be attained. Annex 3, paragraph 1. Where actuation of the parking brake is normally indicated by a separate red warning signal, satisfying all the requirements of paragraph 5.
For example, in the case of a two-axle rear-wheel drive vehicle, with the front axle 1 being braked, the coefficient of adhesion k is given by:. In the case of vehicles equipped with an electric regenerative braking system of category B, having carried out the heating cycles according to paragraph 1.
However, the requirements of paragraph 1. The normal frequency of these verifications shall be once every two years. For fourth order filters the data sampling frequency f s shall be greater than 13,4 f o. The set of braking systems with which a vehicle is equipped shall satisfy the requirements laid down for service, secondary and parking braking systems.
The documentation shall be supported, by an analysis which shows, in overall terms, how the system will behave regulattions the occurrence of any one of those specified faults which will have a bearing on vehicle control performance or safety. A number of tests at increments of line pressure shall be carried out to determine the maximum braking rate of the vehicle z max. Whilst performing the tests described in part B of this annex, the following variables shall be measured:.
An individual compensating value on any axle: It should be understood that during the above test sufficient energy is available in the energy transmission to ensure full actuation of the service braking system. A component made of materials having different characteristics, or a component differing in shape or size; 2.

The recovery performance shall not be less than 70 per cent, nor more than per cent of the figure recorded in this final repeat Type-0 test. Determine lateral displacement by integrating zeroed lateral velocity.
If the wheel-lock sequence test indicates that the rear wheels lock before the front wheels, then the vehicle:. The possibility of a fall-back to partial operation or even to a back-up system for vital vehicle functions may be a part of the safety concept. Checking the wear of the service brake friction components.
Wear of the brakes shall be capable of being easily taken up by means of a system of manual reguations automatic adjustment.
The method by which this may be realised is defined in paragraph 5. In case of a failure, the driver shall be warned for example by warning signal or message display. The brake pedal shall be applied slowly without activating the BAS in the case of category B systems providing a constant increase of deceleration until ABS is fully cycling Figure 3.
Brake linings shall not contain asbestos. This paragraph does not apply to vehicles where the prescribed deceleration values can be reached without the use of electrical energy. The utilisation of adhesion by the anti-lock system shall be checked on complete gegulations equipped with anti-lock systems of categories 1 or 2.
