More Advanced Safety for Tesla Owners

While no car can prevent all accidents, we work every day to make them less likely to occur. The massive amount of real-world data gathered from our cars’ eight cameras, 12 ultrasonic sensors, and forward-facing radar, coupled with billions of miles of inputs from real drivers, helps us better understand the patterns to watch out for in the moments before a crash.

根據我們的每季安全報告，相比於未使用 Autopilot 自動輔助駕駛的駕駛人，使用此功能的駕駛人每英里所發生的事故數更少。這是因為 Autopilot 自動輔助駕駛的設計透過協助駕駛人保持在車道內來降低疲勞駕駛問題，同時確保他們可以持續手握方向盤。雖然使用 Autopilot 自動輔助駕駛時，持續留置駕駛車道以及監控手握方向盤的功能對協助減少事故發生極為有效，但我們仍深信若駕駛人能在沒有使用 Autopilot 自動輔助駕駛時做好這類預防措施，也能極為有效地避免發生事故。

Today, we’re introducing two new safety features designed to help prevent drivers from inadvertently departing their lane, which our data shows is a common cause of accidents when Autopilot is not in use. These new features – Lane Departure Avoidance and Emergency Lane Departure Avoidance – help drivers stay engaged and in their lane in order to avoid collisions.

車道偏離預警
Lane Departure Avoidance lets a driver elect to have corrective steering applied in order to keep them in their intended lane. When the feature is in use and a driver is departing a lane without their turn signal on, the car will also check to see whether a driver’s hands are on the wheel. If a driver’s hands are not detected on the wheel, the driver will receive a series of hands-on reminders and alerts, similar to the ones that our cars provide to customers who use Autopilot. If a driver's hands are repeatedly not detected on the wheel when Traffic Aware Cruise Control is in use, their car will gradually slow down to 15 miles below the speed limit or below the car’s set speed and turn its hazard lights on.

This feature can be turned on or off, and works at speeds between 25 and 90 mph. It is an extension of Lane Departure Warning, which already warns drivers through a steering wheel vibration if they begin to drift out of their lane without their turn signal engaged.

緊急狀況車道偏離迴避
Emergency Lane Departure Avoidance is designed to steer a Tesla vehicle back into the driving lane if our system detects that it is departing its lane and there could be a collision, or if the car is close to the edge of the road. This feature will automatically be enabled at the beginning of every drive, but can be turned off for a single drive by going to the Autopilot Controls menu.

At Tesla, improving safety is our primary goal, even after a customer purchases their car. That’s why we’re introducing these features beginning today via a free over-the-air software update, starting with Model 3 owners and gradually expanding to all cars that were built after October 2016. This is just another way that we are helping to protect Tesla drivers and passengers, and others on the road, every day.
