The normal frequency of these verifications shall be once every two years. In addition they shall be designed such that the driver may, at any time and by deliberate eece, override the function.
Such systems, often controlled by software, are built from discrete functional components such as sensors, electronic control units and actuators and connected by transmission links. Until uniform test procedures have been agreed, the vehicle manufacturer shall provide the technical services ecs their test procedures and results for transient behaviour of the vehicle in the case of failure. Autonomous Steering Systems as defined in paragraph 2.

The transmission is divided into two independent functions: After that point the trailer must fulfill the condition specified in Paragraph 6. R799 of Components A list shall be provided, collating all the units of “The System” and mentioning the other vehicle systems which are needed to achieve the control function in question. Steered wheels The steered wheels shall not be solely the rear wheels. The above approval mark affixed to a vehicle shows that the vehicle type concerned has, with regard to steering equipment, been approved in the Netherlands E4 pursuant to Regulation No.
The electrical control of full power steering systems fitted to trailers, other than additional steering equipment as defined in paragraph 2. Failure of the ASE energy supply.
This may be provided fce a labelled block diagram or other schematic, or by a description aided by such a diagram. The above approval mark affixed to a vehicle shows that the vehicle type concerned has been approved in the Netherlands E4 pursuant to Regulation Nos. If such systems are provided, they shall not be deactivated during type approval testing of the steering system.
The following text extract indicates the scope of the document, but does ede represent the actual PDF content.
Trailers equipped with hydraulic steering transmissions shall rr79 also with Annex 5. Functions of the Units The function of each unit of “The System” shall be outlined and the signals linking it with other units or with other vehicle systems shall be shown.

Trailers equipped with hydraulic steering transmissions shall comply also with Annex 5. However, technologies have advanced to the point where automated systems propose to replace the driver in controlling various aspects of vehicle behavior. Testing requirements for failure 2. This requirement does not apply to semi-trailers.

This will be taken as the basic reference for the verification process set out in paragraph 4. However in the case of a failure in any system which shares the same energy supply steering shall be ensured in accordance with the relevant failure conditions of paragraph 5. Control Systems The requirements of Annex 6 shall be applied to the safety aspects of electronic vehicle control systems that provide or form part of the control transmission of the steering function including advanced driver assistance steering systems.
The requirements of Annex 6 shall be applied to the safety aspects of electronic vehicle control systems that provide or form part of the control transmission of the steering function including advanced driver assistance steering systems. It comprises the electrical wiring and connector and includes the parts for data communication and the electrical energy supply for the trailer control transmission.
After any failure in the steering equipment, or the energy supply, it shall be possible after eight full stroke actuations of the service brake control, to achieve at the ninth application, at least the performance prescribed for the secondary emergency braking system see table below.
However, for trailers with self-tracking steering equipment a test under paragraph 6. It comprises one or both of the following functions: Malfunction or failure of any part of the ASE except for parts not considered to the susceptible to breakdown as specified in paragraph 5. The cables used to supply the trailer electrical energy shall have a conductor cross-sectional area compatible with the continuous current defined in Paragraph 2.
Provisions for trailers having hydraulic steering transmissions. Before the test begins, the tyre pressures shall be as prescribed by the manufacturer for the mass specified in Paragraph 6.
The test manoeuvres shall begin at an energy storage level given in paragraph 5. A second phase in the development of this rule is underway to address the following: Category M 1 vehicles: Confirmation or extension or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 4.
Steering equipment in which the steering forces result solely from one or more energy supplies when the equipment is intact, but in which the steering forces can be provided by the muscular effort of the driver alone if there is a fault in the steering integrated power systemsis also considered to be power assisted steering equipment.
They may include mechanical, electro-pneumatic or electro-hydraulic elements. This requirement must be met from the point the tangent meets the circle to a point 40m along the tangent. When the system is not deactivated by the driver, e.
The verification results shall correspond with the documented summary ecs the failure analysis, to a level of overall effect such that the safety concept and execution are confirmed as being adequate. This Annex does not specify the performance criteria for “The System” but covers the methodology applied to the design process and the information which must be disclosed to the technical service, for type approval purposes.
