Technical 43 www.aftermarketonline.net SEPTEMBER 2024 lane keeping systems, interfere with their driving experience. Striking a balance between safety, performance, and integration to create systems that cooperate with drivers is a real challenge for manufacturers. Drivers must also be aware that ISA is an assistance system and that they remain liable for the safety of their vehicles. Incorrect information provided by ISA does not exempt drivers from speed limit infractions. It can also be overridden or switched off at any time.” What does GSR2 mean for the UK? Many vehicles sold in the UK will use EU specification software as manufacturers try to avoid the additional complexity of creating UKspecific variants, which increases the cost of bringing a vehicle to market. Northern Ireland will adopt GSR2 requirements following the EU type approval process due to the Northern Ireland Protocol, which also adds additional variant complexity. Where there is a difference in regulations within a specific region, manufacturers typically cater to the most complex market, leading to EU specification vehicles likely being sold in the UK. When does GSR2 apply? GSR2 first applied from July 2022 in the first phase, which mandated additional technical requirements on new vehicle models without adding new features. Phase 2 applied to new vehicle models from July 2022, but applied to existing vehicle models from July 2024. This mandated ADAS features such as ISA, AEB, DDAW, and ELKS. Phase 3 also applies from July 2026, mandating an increase in scope to include advanced driver distraction warning (ADDW) and additional pedestrian and cyclist AEB. The regulation only applies to vehicles built after the cut-off dates. No retrofit or software changes are required for any vehicles built before July 6, 2022, or existing models built up to July 7, 2024. Intelligent speed assist ISA recognises traffic signs and provides an overspeed warning. This feature is already fitted to many preGSR2 vehicles. It warns the driver when the speed limit is exceeded to increase speed limit compliance and reduce the severity of collisions. The system uses a forward-facing camera mounted in the windscreen to detect traffic signs in conjunction with speed limits from map data. If the speed limit is exceeded the driver is given visual and audio feedback, typically via a chime and the speed limit flashing within the vehicle instrument cluster. A few select vehicles implement feedback via the accelerator pedal, but most vehicles only employ audio and visual warnings. ISA can be switched off or temporarily overridden by the driver at any time by continuing to apply pressure to the accelerator pedal. &Žƌ ŶĞǁ ǀĞŚŝĐůĞ ŵŽĚĞůƐ ǁŚŝĐŚ ĂƌĞ ŶŽƚ ƚLJƉĞͲĂƉƉƌŽǀĞĚ ;ĐŽŶĮƌŵŝŶŐ ƚŚĂƚ Ă ƉĂƌƟĐƵůĂƌ ǀĞŚŝĐůĞ ǁĂƐ ŵĂŶƵĨĂĐƚƵƌĞĚ ŝŶ ĂĐĐŽƌĚĂŶĐĞ ǁŝƚŚ ƌĞŐŝŽŶĂů ůĞŐŝƐůĂƟŽŶ ĂŶĚ ŐŝǀĞŶ ƚĞĐŚŶŝĐĂů ƐƉĞĐŝĮĐĂƟŽŶƐͿ ďĞĨŽƌĞ ƚŚĞ ĚĞĂĚůŝŶĞ͗ ථ ͻ WŚĂƐĞƐ ϭ ĂŶĚ Ϯ ĂƉƉůŝĞĚ ŝŶ :ƵůLJ ϮϬϮϮ͖ ථ ͻ WŚĂƐĞ ϯ ǁŝůů ĂƉƉůLJ ĨƌŽŵ :ƵůLJ ϮϬϮϰ͘ ථ &Žƌ ĞdžŝƐƟŶŐ ǀĞŚŝĐůĞ ŵŽĚĞůƐ ǁŚŝĐŚ ĂƌĞ ĂůƌĞĂĚLJ ƚLJƉĞ ĂƉƉƌŽǀĞĚ ďLJ ƚŚĞ ĚĞĂĚůŝŶĞ͗ ථ ͻ WŚĂƐĞ ϭ ĂƉƉůŝĞĚ ŝŶ :ƵůLJ ϮϬϮϮ͖ ͻ WŚĂƐĞ Ϯ ǁŝůů ĂƉƉůLJ ĨƌŽŵ :ƵůLJ ϮϬϮϰ͖ ථ ͻ WŚĂƐĞ ϯ ǁŝůů ĂƉƉůLJ ĨƌŽŵ :ƵůLJ ϮϬϮϲ͘ WŚĂƐĞ EŽƚͲƚLJƉĞ ĂƉƉƌŽǀĞĚ ďĞĨŽƌĞ ĚĞĂĚůŝŶĞ dLJƉĞ ĂƉƉƌŽǀĞĚ ďLJ ĚĞĂĚůŝŶĞ ϭ :ƵůLJ ϮϬϮϮ :ƵůLJ ϮϬϮϮ Ϯ :ƵůLJ ϮϬϮϮ :ƵůLJ ϮϬϮϰ ϯ :ƵůLJ ϮϬϮϰ
