Tesla launched a safety scoring system to encourage safe driving and prevent accidents


Tencent technology news on September 26, as Tesla began to launch the “request fully automatic driving test” button to more car owners, the electric vehicle manufacturer also introduced the “safety scoring” system to evaluate the driving behavior of drivers. With this new system, Tesla will effectively encourage car owners to drive safely, which may make the launch of FSD beta and other projects more smooth and prevent more accidents.
The safety scoring system evaluates the driver’s driving behavior and scores based on the five indicators of what the company calls “safety factors”. These factors include forward collision warning (FCW) every 1600 km, hard braking, sharp turning, unsafe following and forced autopilot disengagement. Tesla uses the so-called predicted collision frequency (PCF) formula, which is modeled based on the fleet data of 9.6 billion km, and then predicts how many collisions may occur every 1.6 million km.
The PCF is converted to a security score between 0 and 100 and then viewed through the Tesla application. A higher score indicates driving safety, and most drivers have a safety score of 80 or more.

Tesla also released many tips on how drivers can improve safety scores. In order to improve the rating of forward collision warning (FCW) every 1600 km, Tesla recommends that drivers maintain a follow-up distance so that they have enough time to respond to slow or stationary vehicles in front. When decelerating, depress the brake pedal early and use regenerative braking as safely as possible, which can improve the score of hard braking. Hard braking scores also increase when drivers keep a safe distance from the vehicle in front of them.
A sharp turn is defined as a left or right acceleration exceeding 0.4g (gravitational acceleration). Therefore, drivers can improve their score on this index by turning slowly, reducing speed before turning and gradually accelerating after turning. Unsafe following scores can be easily improved because drivers only need to maintain a tracking distance of a few car lengths from the vehicle in front. In this way, the driver has enough time to respond in case of accidents.
The forced autopilot disengagement highlights the need to use Tesla advanced driver assistance in a responsible manner. The correct use of autopilot is outlined in the owner’s manual. It requires the driver to put his hand on the steering wheel and pay close attention to the road. Tesla pointed out that the forced autopilot disengagement indicator is 1 or 0. If the autopilot is forced to disengage during driving, the value is 1. If the system operates normally, the value is 0.

The safety scoring system is updated every time you drive a Tesla car. If Tesla is connected to the Internet, the safety score should provide immediate feedback on the driving process. Vehicles not connected to the Internet will immediately update their security scoring system while ensuring the security of the cellular connection. It should also be noted that all journeys over 0.6 km are considered valid driving periods, which may affect the driver’s rating.
The safety scoring system also varies from vehicle to vehicle, so drivers with multiple Tesla vehicles may have different ratings for each of their vehicles. Finally, when the vehicle is sold, the safety scoring system should be reset, which means that Tesla’s new car owners should not be affected by the rating of former drivers. If drivers buy a new Tesla, they cannot follow the safety scoring system of the previous vehicle. (reviewed by Tencent technology / Jinlu)
