Note: 2) stop lamp signal under regenerative braking. currently 2 thresholds. no signal under 0.7m/s2. over 1.3 m/s2 must generate signal. in between, may generate signal. OICA concern for one-pedal driving where release of accelerator activates regenerative braking to save energy and brake wear. (akin to endurance braking on heavy vehicles). CP concerns over too many signals under very light deceleration and France concern over when braking stops. Frost recalls that regenerative braking not allowed for use as service braking under Cat A, but can be used under Cat B where braking signal generated. Part of concern to ensure that friction materials remain clean and ready for use. OICA: Cat A regen not part of service braking where Cat B can be part of service braking. Problem is coasting to a stop under regenerative braking where under 0.7 requires brake lights to be turned off. So maybe address concerns by specifying that lights remain on if deceleration continuous from the higher threshold. Reg allows regen blended with service braking, but UK concerned about consistency of user experience between friction braking and regen braking (because regen braking a function of battery charge so not uniform). Chair thinks need to make sure regen requirements fully understood in light of proposed changes. So proposes to adopt (1) and return to discussion of (2) in September. Accepted and, since informal doc, annex to session report.
