Recently, Elon Musk said on Twitter that Tesla is about to update its autopilot Autopilot.
One of the most important is to improve the data processing methods of radar systems. The new autopilot system focuses on improving the processing capabilities of radar signals to make it more difficult to detect old systems before they are detected under ambient light, color, or weather conditions. The identified object.
Tesla’s autopilot system was released in October last year. The system uses radar and cameras, and combines semantic segmentation and other technologies to provide automated driving functions such as lane changing or steering. This feature is available for most Tesla Model S models and all Model X models.
In May of this year, a vehicle owner hit a towing trailer while using the autopilot system, causing the driver to be killed. Initial investigations revealed that under strong sunlight conditions, the autopilot system failed to detect the white body of the tractor-trailer. As a result, Autopilot failed to start the brake system in time. The accident exposed the shortcomings of current algorithms and hardware technology of autopilot technology. A professional pointed out that the monocular camera used by the Model S has flaws in the recognition of three-dimensional and large-area planar objects, limitations in the identification interval of the millimeter-wave radar, and the selection and redundant judgment of comprehensive scenarios in extreme cases. This year, Tesla did not recognize the black Santana in front of the country. At that time, industry insiders believed that there may be a blind spot in the sensor of the Tesla front, which caused the vehicle to fail to identify obstacles within a certain range of angles. The upcoming release of the new version of the system has improved radar signal processing capabilities, making the system better able to handle these difficult-to-judge situations.
We know that Tesla has been creating high-precision overpass maps, and this new version of Autopilo built on off-ramp features can handle highway overpass traffic problems. When the vehicle is about to reach the overpass, the Autopilot system can download map fragments, and the front camera and radar on the car will monitor traffic conditions to ensure smooth roads. After a simple "turn" signal, the vehicle can automatically travel from one road to another. When Autopilot software implements autosteer function, the owner can activate the “turn†signal to exit the road that is driving. At the same time, a more responsive "Traffic-Aware Cruise Control" was introduced in the beta program.
