criterion is reached when the vehicle exceeds the prescribed speed trace tolerance as specified in paragraph 2.6.8.3.1.2. of Annex B6 for 4 consecutive seconds or more. The accelerator control shall be deactivated. The vehicle shall be braked to standstill within 60 seconds.
3.4.4.2. Shortened Type 1 test procedure
3.4.4.2.1. Speed trace
              The shortened Type 1 test procedure consists of two dynamic segments ( and ) combined with two constant speed segments ( and ) as shown in Figure A8/2.

              3.4.4.2.1.1. Dynamic segments
               Each dynamic segment  and  consists of an applicable WLTP test cycle according to paragraph 1.4.2.1. of this annex followed by an applicable WLTP city test cycle according to paragraph 1.4.2.2. of this annex.

    3.4.4.2.1.2. Constant speed segment

              The constant speeds during segments  and  shall be identical. If the interpolation method is applied, the same constant speed shall be applied within the interpolation family.

              (a) Speed specification

                  The minimum speed of the constant speed segments shall be 100 km/h. If the extra high phase (Extra High3) is excluded (as applicable), the minimum speed of the constant speed segments shall be set to 80 km/h. At the request of manufacturer and with approval of the responsible authority, a higher constant speed in the constant speed segments may be selected.

                  The acceleration to the constant speed level shall be smooth and accomplished within 1 minute after completion of the dynamic segments and, in the case of a break according to Table A8/4, after initiating the powertrain start procedure.

                  The deceleration from the constant speed level shall be smooth and accomplished within 1 minute after completion of the constant speed segments.

                  If the maximum speed of the vehicle is lower than the required minimum speed for the constant speed segments according to the speed specification of this paragraph, the required speed in the constant speed segments shall be equal to the maximum speed of the vehicle.

              (b) Distance determination of CSSE and CSSM

                  The length of the constant speed segment  shall be determined based on the percentage of the usable REESS energy  according to paragraph 4.4.2.1. of this annex. The remaining energy in the traction REESS after dynamic speed segment  shall be equal to or less than 10 per cent of . The manufacturer shall provide evidence to the responsible authority after the test that this requirement is fulfilled.

                  The length  of constant speed segment CSSM may be calculated using the following equation:

                       where:

                       dCSSM is the length of constant speed segment CSSM, km;

                        is the estimated pure electric range of the considered PEV, km;

                        is the length of dynamic speed segment 1, km;

                        is the length of dynamic speed segment 2, km;
