Recently, Tesla conducted an OTA upgrade and started pushing the 2024.20.9 version in batches. The focus of this upgrade includes optimizing the sensor diagnostic function of the electronic brake assist system, optimizing the Autopilot automatic driving assistance disable logic, allowing the air conditioning to cool down faster, and allowing the vehicle to better regulate the temperature of the high-voltage battery to improve overcharging performance.
The collective content of this OTA upgrade is as follows:
1. Update the sign of the turn signal light signal device.
2. Optimize the sensor diagnostic function of the electronic brake assist system.
3. Optimize the prompt function for the backup box cover not being closed before optimization.
4. Optimize the Autopilot automatic assisted driving disable logic: As long as you do not receive any disable warnings within seven days, there will be one automatic driving disable count waived. Every time you receive a disable warning, this counter will restart.
5. Security improvement: Fix out of bounds read vulnerabilities and arbitrary code execution vulnerabilities.
6. Multiple improvements that can optimize vehicle performance in hot weather: air conditioning can cool the cab faster; Vehicles can better regulate the temperature of high-voltage batteries to improve overcharging performance.
