APPENDIX 3

     'Vehicle Stability Function' requirements for category ME vehicles and category NC vehicles (as required by clause 5.1.8)

 1.                                  Definitions
     1.                            'Ackerman Steer Angle' means the angle whose tangent is the 'Wheelbase' divided by the radius of the turn at a very low speed.
     2.                            'Automatically Commanded Braking' means a function within a complex electronic control system where actuation of the braking system(s) or brakes of certain axles is made for the purpose of generating vehicle retardation with or without a direct action of the driver, resulting from the automatic evaluation of on board initiated information.
     3.                            'Cab-over engine vehicle' means a vehicle where more than half of the engine length is rearward of the foremost point of the windshield base and the steering wheel hub is in the forward quarter of the vehicle length.[7]
     4.                            'Control Trailer' means a 'Semi-trailer' in accordance with clause 3 of Annex 1 to this appendix.
     5.                            'Directional Control' means a function within a 'Vehicle Stability Function' that assists the driver, in the event of 'Understeer' and 'Oversteer' conditions, within the physical limits of the vehicle in maintaining the direction intended by the driver in the case of a power-driven vehicle, and assists in maintaining the direction of the trailer with that of the towing vehicle in the case of a trailer.
