Distribution of mass of each axle maximum value: Therefore, sufficient energy level shall be ensured at the beginning of the test. If it is a foot control device, the force exerted on the control shall not exceed 50 daN. The minimum performance prescribed shall be attained. The dynamic load on the axle shall be that given by the formulae in Annex 5 to this Regulation.
Vehicles fitted for invalid drivers. The braking test shall be conducted with the engine disconnected and idling, and with the vehicle laden. The value for time at the zero reglations steering wheel angle is interpolated. Application for approval 4. Pedal force is increased at a linear rate such that the first axle lockup occurs no less than one-half 0,5 second and no more g13 one and one-half 1,5 seconds after the initial application of the pedal. The energy storage device s for pneumatic auxiliary equipment shall be isolated.

Service braking system The service braking system shall make it possible to control the movement of the rebulations and to halt it safely, speedily and effectively, whatever its speed and load, on any up or down gradient. On completion of the tests required under paragraph 4. In the case of the latter Regulation the corrected absorption coefficient is 1,30 m —1.
The vehicle shall be unladen. The service braking control rregulations then be fully actuated four times in succession with the vehicle stationary.
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. Condition the tyres using the procedure of paragraphs 5.
The systems providing service, secondary and parking braking may have common components so long as they fulfil the following conditions: Alternatively, this protection requirement is fulfilled when a secondary means of checking the correct operational status is available.
If auxiliary equipment is supplied with energy from the same reserve as the electric control transmission, it shall be ensured that, with the engine running at a speed not greater than 80 per cent of the maximum power speed, the supply of energy is sufficient to fulfil the prescribed deceleration values by either provision of an energy supply which is able to prevent discharge of this reserve when all auxiliary equipment is functioning or by automatically switching off pre-selected parts of the auxiliary equipment at a voltage above the critical level referred to in paragraph 5.
In braking tests, and in particular in those at high speed, the general behaviour of the vehicle during braking shall be checked. During the tests provided in paragraphs 5.
In case of a failure, the driver shall be warned for example by warning signal or message display. Vehicles using other types of steering control may also be approved to this annex provided the manufacturer is able to demonstrate to the Technical Service that the performance requirements of this annex can be met using equivalent steering inputs to the steering inputs r1 under paragraph 5 of this part.

The alternative types of brake r3 shall be checked by comparing their performance with that obtained from the brake linings with which the vehicle was equipped at the time of approval and conforming to the components identified in eece relevant information document, a model of which is given in Annex 1 to this Regulation. The braking force varies proportionally as the action on the control monotonic function. The procedure described in this annex may be applied in the event of a modification of vehicle type resulting from the fitting of brake linings of another type to vehicles which have been approved in accordance with this Regulation.
If the holder of the approval completely ceases to manufacture a type of vehicle approved in accordance with this Eec, he shall so inform the Type Approval Authority which granted the approval.

Verify that the ESC malfunction indicator again illuminates to signal a malfunction and remains illuminated as long as the engine is running or until eegulations fault is corrected. The performance prescribed in paragraph 5.
This procedure is applicable to vehicle batteries used for traction and regenerative braking. The requirement of paragraph 3. Sine with Dwell test of oversteer intervention and responsiveness. Names and addresses of the Technical Services conducting approval tests, and of Type Approval Authorities Master cylinder type and size: On vehicles to which the coupling of a trailer is rsgulations, the parking braking system of the motor vehicle shall be capable of holding the combination of vehicles stationary on a 12 per cent up or down gradient.
The mean fully developed deceleration d m shall be calculated as the deceleration averaged with respect to distance over the interval v b to v eaccording to the following formula:.
That has an algorithm to determine the need, and a means to modify propulsion torque, as necessary, to assist the driver in maintaining control of the vehicle. Simulate one or more ESC malfunction s by disconnecting the power source to any ESC component, or disconnecting any electrical connection between ESC components with the vehicle power off.
The example in Figure 3 has its origin at the time t 0 crossing the a ABS line 2 seconds. The driver shall be able to achieve this braking action from his driving seat without removing his hands from the steering control.
