The 4th session of the Acceleration Control for Pedal Error Global Technical Regulation was held online on 8 July 2026. The agenda was endorsed without comment. The draft report for the previous meeting was revised as ACPE-GTR-03-06/Rev.1. Japan presented planned research activities including testing in reverse direction. Canada clarified that false positive test procedures still need to be defined and aim to provoke undesired ACPE intervention. Germany, Korea, Norway, and United Kingdom reported on their respective research status. ACPE-GTR-02-07/Rev.1 was presented. The next confirmed meetings are scheduled for 8 September 2026 and 10 November 2026.

The agenda includes discussion of preliminary outcomes and planning research activities. Future sessions are scheduled for September 8th, 2026, November 10th, 2026, and January 2027 in Japan before GRVA-27.

Transport Canada ACPE Research Plan 2026 sets out testing expected August and September 2026, with preliminary results expected in November. Testing addresses sonar sensor response to different materials, ACPE system characterization including coarse and refined screening with varying accelerator application rates, distances, target types, speeds, and directions, baseline response with no obstacle, and false positives using test vehicles 2026 Passport, 2026 Solterra, and 2026 Prius.

Research plan for ACPE vehicle performance. Tests using actual vehicles will evaluate ACPE performance of vehicles on the Japanese market. Tests specified in UN R175 01 series will be conducted, along with tests under extended conditions with partially expanded test parameters. Test procedure for creeping vehicle specified in UN R175 01 series, paragraph 6.6.2, will be conducted. Activation limits of ACPE will be confirmed using distance to target and pedal application speed as test parameters. Tests will use one 2026 model year Suzuki Swift and one 2026 model year Daihatsu Move. Vehicle procurement by end of September, testing late October to November, data analysis by end of December, summary of research results early January.
