Reversing warning measurements on competitors TF-RWS 6th Meeting in PARIS (OICA) Groupe RENAULT Joseph de Courtivron 26/06/2019

VeHicle TECHNICAL definition Category : N1 3,5t > MMAC >2,5t Length : 5,41m Height : 2,52m Engine : Thermal combustion engine Vehicle 2 Category : N1 3,5t > MMAC >2,5t Length : 5,986m Height : 2,59m Engine : Electric engine DEA-TUP6 / J. de COURTIVRON

VeHicle TECHNICAL definition The device is located on the left rear under the body, directed to the ground. Vehicle 2 The device is located on the right rear under the body, directed to the right. DEA-TUP6 / J. de COURTIVRON

Measurement conditions +0,5 to +1,5m from the ground RW700 +7m from de back of the Van RW08 (8cm under the device as a reference) ±0,10m from the longitudinal axis of the Van RW700 Conditions : Open area, good weather Static Engine ON , reverse gear engaged 3 runs each time DEA-TUP6 / J. de COURTIVRON

Height Impact on SPL (vehicule 2) +0,5 to +1,5m from the ground RW700 DEA-TUP6 / J. de COURTIVRON

LAFmax : The maximum level with A-weighted frequency response and Fast time constant. RESULTS Vehicle 1   Configuration Duration (s) LAF MAX (dBA) * Measured on open asphalt area back ground noise Before Engine Off 10 51 Engine On 53 After Engine Off / Device Off 50 Engine On / Device Off Microphone : RW700 Run 1 - Engine On 60 Run 2 - Engine On Run 3 - Engine On 61 * no correction applied, gap less than 10dBA Noise Tonal Sound Intermittent : 24/min Delta t 2,5s Vehicle 2 LAF MAX (dBA) Measured on ISO Track Run 1 35 Run 2 Run 3 36 77 75 76 Intermittent : 100/min 0,6s Max SPL @ 1,5m (height) DEA-TUP6 / J. de COURTIVRON
