Generation of a braking signal to illuminate stop lamps. Description of the vehicle type: Once full deceleration has been achieved, the brake pedal shall be operated so that the ABS continues fully cycling.

Documentation shall be brief, yet provide evidence that the design and development has had the benefit of expertise from all the system fields which are involved. A list of the components, duly identified, fce the braking equipment; 3. General performance characteristics for category “A” BAS systems When an emergency condition has been sensed by a relative high pedal force, the additional pedal force to cause full cycling of the ABS shall be reduced compared to the pedal force required without the BAS system in operation.

The road shall have a surface affording good adhesion, unless specified otherwise in the relevant annexes. Type-0 test ordinary performance test with cold brakes. In addition, if the muscular effort applied by the driver to the parking braking system is reinforced by a servo device, the actuation of parking braking shall be ensured in the event of a failure of the servo device, if necessary by using a reserve of energy independent of that normally supplying the servo device.

Following completion of the final stop in paragraph 5. The vehicle manufacturer shall provide a tell-tale indicating that the vehicle has been put into a mode that renders it unable to satisfy the requirements of paragraphs 3, 3.

However, the requirements of paragraph 1. Data processing for the BAS. F T and a T are threshold force and threshold deceleration as shown in Figure 1a. 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.

The vehicle shall be unladen. Brake lining equivalence shall be based on a comparison of the results achieved using the test procedures prescribed in this annex and in accordance with the following requirements. Anti-aliasing filters shall be of order 4 or higher and the relevant data range f max shall be 0 Hz to 30 Hz.

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. Such systems, often controlled by software, are built from discrete fce components such as sensors, electronic control units and actuators and connected by transmission links.

If wheel lockup commences at a braking rate less than 0,15 and more than 0,8 then the test is invalid and should be repeated on a different road surface. 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.

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. 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.

The steering amplitude of the final run in each series is the greater of 6,5 A or degrees, provided the calculated magnitude of 6,5 A is less than or equal to degrees.

Use of the dynamic stability simulation. The yaw rates at 1,0 and 1,75 seconds after COS are determined by interpolation.

ECE Regulation 90

The tests may be conducted without a regenerative braking component. After the braking equipment is first energised and the signal has ec that, following the procedures detailed in paragraph 5. In an emergency manoeuvre, the time elapsing between the moment when the control device begins to be actuated and the moment when the braking force on the least favourable placed axle reaches the fce corresponding to the prescribed performance shall not exceed 0,6 seconds.

Laden; where provision is made for several possibilities of load distribution, the one whereby the front axle is the most heavily laden shall be the one considered.

When the brakes are applied for the fifth time, it shall be possible to brake the vehicle with at least the performance prescribed for secondary braking of the laden vehicle. Certain parts, such as the pedal and its bearing, the master cylinder and its piston or pistons, the control valve, the linkage between the pedal and the master cylinder or the control valve, the brake cylinders and their pistons, and the lever-and-cam assemblies of brakes, shall not be regarded as liable to breakage if they are amply dimensioned, are readily accessible for maintenance, and exhibit safety features at least equal to those prescribed for other essential components such as the steering linkage of the vehicle.


Master cylinder type and size: A diagram of assembled braking equipment and an indication of the position of its components on the vehicle; 3. Tests are conducted on a dry, uniform, solid-paved surface. It shall be accompanied by the under-mentioned documents in triplicate r13b by the following particulars:.

EUR-Lex – X(01) – EN – EUR-Lex

In the case of vehicles equipped with category 3 anti-lock systems, only the axle s with at least one directly controlled wheel shall satisfy this requirement. However, for hydraulic braking systems with stored energy, these provisions can be considered to be met provided that the requirements of paragraph 1. Vehicle stability function simulation tool test report.

The secondary braking system shall make it possible by application of the service brake control to halt the vehicle within a reasonable distance in the event of failure of the service braking system. Vehicles equipped 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.

Except as provided in paragraph 3. Subject to the requirements of paragraphs That has a means to monitor driver steering inputs; and 2. The above approval mark affixed to a vehicle shows that the vehicle type concerned has, with regard to braking, been approved in the United Kingdom E 11 pursuant to Regulation No H under approval number
