      2.2.   Definitions
      2.2.1.   Mass of a disc or drum
      
                  2.2.1.1.
               
               
                  The “declared mass” is the mass declared by the manufacturer which is a representative mass for the brake identifier (see paragraph 3.7.2.2 of this Appendix).
               
            
                  2.2.1.2.
               
               
                  The “nominal test mass” is the mass which the manufacturer specifies for the disc or drum with which the relevant test is carried out by the Technical Service.
               
            
                  2.2.1.3.
               
               
                  The “actual test mass” is the mass measured by the Technical Service prior to the test.
               
            2.2.2.   “Brake input threshold torque”:
      
                  2.2.2.1.
               
               
                  The brake input threshold torque “C0” is the input torque necessary to produce a measurable brake torque. This torque may be determined by extrapolation of measurements within a range not exceeding 15 percent braking rate or other equivalent methods (e.g. Annex 10, paragraph 1.3.1.1).
               
            
                  2.2.2.2.
               
               
                  The brake input threshold torque “C0,dec” is the brake input threshold torque declared by the manufacturer which is a representative brake input threshold torque for the brake (see paragraph 3.7.2.2.1 of this Appendix) and is needed to produce diagram 2 of Annex 19.
               
            
                  2.2.2.3.
               
               
                  The brake input threshold torque “C0,e” is determined by the procedure as defined in paragraph 2.2.2.1 above, measured by the Technical Service at the end of the test.
               
            2.2.3.   “External diameter of a disc”:
      
                  2.2.3.1.

                                 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;

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 (22):

                     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 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.

                     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.

                        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.   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)

                        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)
                     
                     
                        the electronic control box in a hardware-in-the-loop configuration.
                     
                  1.3.   In the case of a trailer, the simulation shall be carried out with the trailer coupled to a representative towing vehicle.
            1.4.   Vehicle loading condition
            
                        1.4.1.
                     
                     
                        The simulator shall be able to take into account the laden and unladen conditions.
                     
                  
                        1.4.2.
                     
                     
                        The load shall be considered to be a fixed load with properties (mass, mass distribution and maximum recommended height of the centre of gravity) specified by the manufacturer.
                     
                  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):
                        
                                    (a)
                                 
                                 
                                    yaw velocity;
                                 
                              
                                    (b)
                                 
                                 
                                    lateral acceleration;
                                 
                              
                                    (c)
                                 
                                 
                                    wheel load or wheel lift;
                                 
                              
                                    (d)
                                 
                                 
                                    forward velocity;
                                 
                              
                                    (e)
                                 
                                 
                                    driver input.
                                 
                              
                  
                        2.2.
                     
                     
                        The objective is to show that the simulated vehicle behaviour and operation of the vehicle stability function is comparable with that seen in practical vehicle tests.
                     
                  
                        2.3.
                     
                     
                        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.
