| Summary | UN R51 allows the use mechanical or electronic devices to control the gear shifting and measures to avoid accelerations greater than 2.0 m/s2. However, the measures are not defined and the manufacturer or technical service is not obliged to document the methodology in the test report. This proposal would introduce a table with examples for devices and measures for reference and would require documentation of methodology used. | ||||||||

11. The expert from OICA proposed amendments to Regulation No. 51 with the aim to ensure transparency during the type approval process in situations where the manufacturer could either use mechanical or electronic devices to control the gear shift, or take measures to avoid accelerations greater than 2.0 m/s² (ECE/TRANS/WP.29/GRB/2018/2 and GRB-67-17). The proposal received questions and/or comments from the experts of China, France, Germany, Japan and ISO. GRB adopted the proposals, as contained in Annex III to the session report, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2018 sessions as a draft Supplement 4 to the 03 series of amendments to Regulation No. 51. |
