‘ANNEX 21

Special requirements for vehicles equipped with a vehicle stability function

1.   GENERAL
This annex defines the special requirements for vehicles equipped with a vehicle stability function, pursuant to paragraphs 5.2.1.32 and 5.2.2.23 of this Regulation.
2.   REQUIREMENTS
2.1.   Power-driven vehicles








2.1.1.


Where a vehicle is equipped with a vehicle stability function as defined in paragraph 2.34 of this Regulation, the following shall apply:





In the case of directional control the function shall have the ability to automatically control individually the speed of the left and right wheels on each axle or an axle of each axle group (14) by selective braking based on the evaluation of actual vehicle behaviour in comparison with a determination of vehicle behaviour demanded by the driver (15).









In the case of roll-over control the function shall have the ability to automatically control the wheel speeds on at least two wheels of each axle or axle group (14) by selective braking or automatically commanded braking based on the evaluation of actual vehicle behaviour that may lead to vehicle roll-over (15).









In both cases, the function is not required:





(a)


When the vehicle speed is below 20 km/h;









(b)


Until the initial start-up self test and plausibility checks have been completed;









(c)


When the vehicle is being driven in reverse.




















2.1.2.


To realise the functionality defined above a vehicle stability function shall include, in addition to selective braking and/or automatically commanded braking, at least the following:






(a)


The ability to control engine power output;










(b)


In the case of directional control: The determination of actual vehicle behaviour from values of yaw rate, lateral acceleration, wheel speeds, and from the driver’s control inputs to the braking and steering systems and to the engine. Only on-board generated information shall be used. If these values are not directly measured, the evidence of the appropriate correlation with directly measured values under all driving conditions (e.g. including driving in a tunnel) shall be shown to the technical service at the time of type approval;










(c)


In the case of roll-over control: The determination of actual vehicle behaviour from values of the vertical force on the tyre(s) (or at least lateral acceleration and wheel speeds) and from the driver’s control inputs to the braking system and to the engine. Only on-board generated information shall be used. If these values are not directly measured, the evidence of the appropriate correlation with directly measured values under all driving conditions (e.g. including driving in a tunnel) shall be shown to the technical service at the time of type approval;










(d)


In the case of a towing vehicle equipped according to paragraph 5.1.3.1 of this Regulation: The ability to apply the service brakes of the trailer via the respective control line(s) independently of the driver.
















2.1.3.


The vehicle stability function shall be demonstrated to the Technical Service by dynamic manoeuvres on one vehicle. This may be realized by a comparison of results obtained with the vehicle stability function enabled and disabled for a given load condition. As an alternative to carrying-out dynamic manoeuvres for other vehicles and other load conditions, fitted with the same vehicle stability system, the results from actual vehicle tests or computer simulations may be submitted.
The use of the simulator is defined in Appendix 1 to this Annex.
The specification and validation of the simulator is defined in Appendix 2 to this Annex.
Until unified test procedures are agreed, the method by which this demonstration is carried out shall be agreed between the vehicle manufacturer and the Technical Service and shall include the critical conditions of directional control and roll-over control as appropriate to the vehicle stability function installed on the vehicle with the method of demonstration and results being appended to the type approval report. This may be carried-out other than at the time of type approval.
As a means of demonstrating the vehicle stability function any of the following dynamic manoeuvres shall be used (16):






Directional control


Roll-over control




Reducing radius test


Steady state circular test




Step steer input test


J-turn




Sine with dwell


 




J-turn


 




μ-split single lane change


 




Double lane change


 




Reversed steering test or “fish hook” test


 




Asymmetrical one period sine steer or pulse steer input test


 




To demonstrate repeatability the vehicle will be subject to a second demonstration using the selected manoeuvre(s).












2.1.4.


Interventions of the vehicle stability function shall be indicated to the driver by a specific optical warning signal. The indication shall be present as long as the vehicle stability function is in an intervention mode. The warning signals specified in paragraph 5.2.1.29 of this Regulation shall not be used for this purpose.
Interventions of the vehicle stability function used in any learning process to determine the vehicle operational characteristics shall not generate the above signal.
The signal shall be visible to the driver, even in daylight, such that the driver can easily verify the satisfactory condition of the signal without leaving the driver’s seat.












2.1.5.


A vehicle stability function failure or defect shall be detected and indicated to the driver by the specific yellow optical warning signal referred to in paragraph 5.2.1.29.1.2 of this Regulation.
The warning signal shall be constant and remain displayed as long as the failure or defect persists and the ignition (start) switch is in the “on” (run) position.












2.1.6.


In the case of a power-driven vehicle equipped with an electric control line and electrically connected to a trailer with an electric control line the driver shall be warned by a specific optical warning signal whenever the trailer provides the information “VDC Active” via the data communications part of the electric control line. The optical signal defined in paragraph 2.1.4 above may be used for this purpose.




2.2.   Trailers








2.2.1.


Where a trailer is equipped with a vehicle stability function as defined in paragraph 2.34 of this Regulation, the following shall apply:





In the case of directional control the function shall have the ability to automatically control individually the speed of the left and right wheels on each axle or an axle of each axle group (14) by selective braking based on the evaluation of actual trailer behaviour in comparison with a determination of the relative behaviour of the towing vehicle (15).









In the case of roll-over control the function shall have the ability to automatically control the wheel speeds on at least two wheels of each axle or axle group (14) by selective braking or automatically commanded braking based on the evaluation of actual trailer behaviour that may lead to roll-over (15).
















2.2.2.


To realise the functionality defined above a vehicle stability function shall include, in addition to automatically commanded braking and where appropriate selective braking, at least the following:






(a)


The determination of actual trailer behaviour from values of the vertical force on the tyre(s), or at least lateral acceleration and wheel speeds. Only on-board generated information shall be used. If these values are not directly measured, the evidence of the appropriate correlation with directly measured values under all driving conditions (e.g. including driving in a tunnel) shall be shown to the technical service at the time of type approval.
















2.2.3.


The vehicle stability function shall be demonstrated to the Technical Service by dynamic manoeuvres on one vehicle. This may be done by a comparison of results obtained with the vehicle stability function enabled and disabled for a given load condition. As an alternative to carrying-out dynamic manoeuvres for other vehicles and other load conditions, fitted with the same vehicle stability system, the results from actual vehicle tests or computer simulations may be submitted.
The use of the simulator is defined in Appendix 1 to this Annex.
The specification and validation of the simulator is defined in Appendix 2 to this Annex.
Until unified test procedures are agreed, the method by which this demonstration is carried out shall be agreed between the trailer manufacturer and the Technical Service and shall include the critical conditions of roll-over control and directional control as appropriate to the vehicle stability function installed on the trailer with the method of demonstration and results being appended to the type approval report. This may be carried-out other than at the time of type approval.
As a means of demonstrating the vehicle stability function any of the following dynamic manoeuvres shall be used (16):






Directional control


Roll-over control




Reducing radius test


Steady state circular test




Step steer input test


J-turn




Sine with dwell


 




J-turn


 




μ-split single lane change


 




Double lane change


 




Reversed steering test or “fish hook” test


 




Asymmetrical one period sine steer or pulse steer input test


 




To demonstrate repeatability the vehicle will be subject to a second demonstration using the selected manoeuvre(s).












2.2.4.


Trailers equipped with an electric control line, when electrically connected to a towing vehicle with an electric control line, shall provide the information “VDC active” via the data communications part of the electric control line when the vehicle stability function is in an intervention mode. Interventions of the vehicle stability function used in any learning process to determine the trailer operational characteristics shall not generate the above information.












2.2.5.


To maximise the performance of trailers that utilise “select-low” such trailers are permitted to change control mode to “select-high” during an intervention of the “Vehicle Stability Function”.






‘APPENDIX 1

Use of the dynamic stability simulation

The effectiveness of the directional and/or roll-over stability control function of power-driven vehicles and trailers of categories M, N and O, may be determined by computer simulation.
1.   USE OF THE SIMULATION








1.1


The vehicle stability function shall be demonstrated by the vehicle manufacturer to the Type Approval Authority or Technical Service with the same dynamic manoeuvre(s) as for the practical demonstration in paragraph 2.1.3 or 2.2.3 of Annex 21.












1.2.


The simulation shall be a means whereby the vehicle stability performance may be demonstrated with the vehicle stability function enabled or disabled, and in the laden and unladen conditions.












1.3.


The simulations shall be carried out with a validated modelling and simulation tool. The verification shall be carried out using the same manoeuvre(s) as defined in paragraph 1.1 above.
The method by which the simulation tool is validated is given in Annex 21, Appendix 2.








‘APPENDIX 2

Dynamic stability simulation tool and its validation

1.   SPECIFICATION OF THE SIMULATION TOOL
1.1.   The simulation method shall take into account the main factors which influence the directional and roll motion of the vehicle. A typical model may include the following vehicle parameters in an explicit or implicit form:






(a)


axle/wheel;










(b)


suspension;










(c)


tyre;










(d)


chassis/vehicle body;










(e)


power train/driveline, if applicable;










(f)


brake system;










(g)


payload.




1.2.   The Vehicle Stability Function shall be added to the simulation model by means of:






(a)


a subsystem (software model) of the simulation tool; or










(b)

2.   VALIDATION OF THE SIMULATION TOOL








2.1.


The validity of the applied modelling and simulation tool shall be verified by means of comparisons with a practical vehicle test(s). The test(s) utilised for the validation shall be those which, without control action, would result in loss of directional control (under-steer and over-steer) or roll-over control as appropriate to the functionality of the stability control function installed on a representative vehicle.
During the test(s) the following motion variables, as appropriate, shall be recorded or calculated in accordance with ISO 15037 Part 1:2005: General conditions for passenger cars or Part 2:2002: General conditions for heavy vehicles and buses (depending on the vehicle category):

lateral acceleration;










(c)


wheel load or wheel lift;










(d)


forward velocity;










(e)


driver input.
















2.2.

The simulator shall be deemed to be validated when its output is comparable to the practical test results produced by a given vehicle type during the selected manoeuvre(s) from those defined with paragraph 2.1.3 or 2.2.3 of Annex 21, as appropriate.
In the case of the steady state circular test the under-steer gradient shall be the means of making the comparison.
In the case of a dynamic manoeuvre, the relationship of activation and sequence of the vehicle stability function in the simulation and in the practical vehicle test shall be the means of making the comparison.












2.4.


The physical parameters that are different between the reference vehicle and simulated vehicle configurations shall be modified accordingly in the simulation.












2.5.


A simulator test report shall be produced, a model of which is defined in Appendix 3 of this Annex, and a copy attached to the vehicle approval report.
