Tesla has an update for the Sentry Mode that drastically reduces power consumption. With software version 2024.38.4, the feature starts on the Cybertruck and will also be available for other Tesla-models in the future. Thanks to new architectural approaches Tesla improve the energy efficiency of the safety mode by an impressive 40%.
How does Sentry Mode work?
Challenge: High power consumption
Sentry Mode monitors the vehicle with cameras, saves recordings and keeps important systems active. Until now, Tesla's main computer - the Media Control Unit (MCU) and the FSD computer - were continuously powered, even when the vehicle was not in operation. This operation drew around 250 watts, which put a strain on the battery, especially when the vehicle was stationary for long periods.
Technical changes in detail
In order to reduce power consumption Tesla has made decisive changes:
-
New distribution of tasks:
The FSD computer now perform tasks such as motion detection and video compressionwhile the MCU is only activated when data needs to be written to a USB drive. -
Processor isolation:
The separation between the MCU and FSD computer makes it possible to optimize systems independently of each other and even restart them if necessary. -
Kernel optimizations:
Through the underclocking of processors and other software optimizations has Tesla further reduced energy consumption.
Additional savings
Tesla has also been achieved by USB port usage to avoid wasting energy. USB ports and 12V sockets now remain deactivated if they are not absolutely necessary.
What are the benefits of the update?
Improved battery life
Thanks to the more efficient use of the systems, the battery remains charged significantly longer when Sentry Mode is activated - a major advantage for drivers who park their vehicles for longer periods of time.
Future-oriented technology
While the update was first released on the Cybertruck was first introduced on the Cybertruck, the changes will soon be rolled out to other Tesla-models such as the Model 3 and Model Y will be available.
Additional applications
The new features may not only affect Sentry Mode. Functions such as Dashcam recordings and the Summon standby modewhere the vehicle waits for commands from the driver, could also benefit from the improvements.
Conclusion: More efficiency, less power consumption
Tesla The latest updates show how continuous improvements in software development can lead to increased efficiency. The optimized Sentry Mode not only makes the vehicle safer, but also more environmentally friendly - another step in Tesla's mission to redefine the mobility of the future.
