Transport Canada presented ACPE research testing comparing three vehicles—2025 Tesla Model 3, 2025 Subaru Forester, and 2025 Toyota Crown Signia—against UN R175 minimum performance requirements and real-world pedal misapplication crashes. Analysis of 14 EDR data cases revealed none would require ACPE intervention under current R175 criteria. Testing included UN R175 procedures and recreation of six real-world crash scenarios. Proposed 2026 research includes investigating radar signatures of wall structures, obstacle distances exceeding 1.5 metres, accelerator pedal application rates and travel, and false positive test procedures.

Proposal to insert provisions on Software Identification Numbers and software updates across UN R13, R13-H, R79, R89, R130, R131, R152, R155, R156, R157, R171, R175, and R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7 paragraph 2, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance with test reports, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered vehicles from new vehicles where type approval regulations are updated or hardware changes occur in series production with test duplication avoided where possible, clarifying that production is not considered definitively discontinued if manufacturers obtain subsequent extensions for software updates of registered vehicles, renumbering and inserting new items in approval communication annexes for R13SWIN, R13-HSWIN, R79SWIN, R89SWIN, R130SWIN, R131SWIN, R152SWIN, R155SWIN, R157SWIN, R171SWIN, R175SWIN, and R178SWIN information including whether held on vehicle and relevant parameter identification lists, and amending R157 and R171 to align software update requirements with R156 technical specifications and transitional provisions.

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.

Proposal to insert provisions on software identification and software updates into UN R13, UN R13-H, UN R79, UN R89, UN R130, UN R131, UN R152, UN R156, UN R157, UN R171, UN R175, and UN R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles, clarifying that production discontinuation does not apply when manufacturers seek approval extensions for software updates of registered vehicles, and amending communication forms to include software identification numbers and related information.

No vehicles have received certification under UN R175-00/01. The document lists representative ACPE-equipped vehicle models from various manufacturers and markets, detailing their sensor configurations, target objects, and operation speed ranges. Sensor types include ultrasonic sonar, monocular camera, stereo camera, and milli-wave radar. Target objects are stationary objects and pedestrians. Vehicles exhibit variation in forward and rearward equipment and low-speed braking function inclusion. Performance definitions differ by OEM and are not directly comparable across manufacturers or to UN R175 requirements.

Proposal to amend UN R13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178 by introducing provisions on software identification and software updates. Amendments add new paragraphs referring to Software Identification Number definitions in Consolidated Resolution R.E.3, require manufacturers to provide Technical Services with information on hardware and software influencing performance, permit vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles while avoiding test duplication, and modify production discontinuation provisions to exclude cases where manufacturers seek approval extensions for software updates of registered vehicles.

The draft document identifies potential research questions for ACPE (Acceleration Control for Pedal Error) systems across three categories: basic data collection on system specifications and cost-benefit analysis; performance requirements and test procedures; and human factors analysis. Research priorities include surveying existing ACPE technologies, analyzing accident data and system costs, establishing control philosophy, defining triggering conditions, and investigating pedal misapplication.
