Tesla Upgrades Safety Features for Legacy MCU1 Vehicles
Tesla is enhancing the safety features of its older MCU1 vehicles with the latest software update, 2024.26.3.1. This update brings notable improvements, including the addition of Full Self-Driving (FSD) Version 12, alongside several critical safety upgrades.
Enhanced Automatic Emergency Braking
The Automatic Emergency Braking (AEB) system for MCU1 vehicles has received a substantial upgrade. Previously introduced in the 2023.12 software update, AEB now supports reverse driving, a feature that was not initially highlighted in release notes but was detailed in the 2023.12 owner’s manual. Tesla has now officially included this feature in their release notes.
The release notes mention: “Automatic Emergency Braking now operates in Reverse (R) as well as Drive (D). The system will apply the brakes if it detects an object in its path and determines that a collision is imminent. AEB is enabled by default each time you drive.”
This update may also enhance AEB functionality at speeds above 100 mph, improving collision impact reduction. Tesla’s continuous focus on safety innovation is commendable.
Improved Perpendicular Hazard Response
A significant improvement in AEB is its ability to react to perpendicular hazards, such as vehicles running red lights or cutting across your path. This update marks a major advancement from the standard braking system that only responds to vehicles directly in front. Although this feature is not explicitly mentioned in the MCU1 release notes, it is likely included given the new AI model in FSD v12.
Upgraded Forward Collision Warning
Additionally, Tesla has refined its Forward Collision Warning (FCW) system. FCW events will now trigger haptic feedback, complementing the existing audible and visual alerts.
These AEB upgrades require Hardware 3 (HW3), available as a free upgrade from HW2 for those with Full Self-Driving (FSD) packages.
Tesla’s efforts to enhance safety and functionality for older vehicles, some dating back to 2016, underscore their commitment to continual improvement. This ongoing support is reassuring for owners of both Hardware 3 and MCU1 vehicles, promising future advancements and reliability.
