Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens for the delivery of digital whale clues! CTOnews.com March 20 news, Tesla has been in North America to promote 2022.45.11 car software update. This version mainly fixes the recall issue, and FSD Beta is updated to v11.3.2. This push has a wider range of users than previous versions.

Enable FSD Beta on the highway. This unifies the vision and planning stack on the highway and off-highway, and replaces the traditional highway stack, which has a history of more than four years. According to reports, Tesla's traditional highway stack relies on a single camera and single-frame network, and can only handle simple lane-specific mobility logic, while FSD Beta can use multi-camera networks and next-generation planners to achieve more complex agent interaction and reduce dependence on lanes, which is also to make way for more intelligent behavior, smoother control and better decision-making.

By getting more data from the self-driving test fleet, the recall rate in close-up situations has been increased by 15%, especially for large trucks and high yaw rate scenarios. In addition, FSD extends and adjusts dedicated speed control for cut-in objects.

The position of the car body in the wide lane has been improved to allow other cars to bypass by deflecting the coming turn.

Improved maneuverability in high curvature or large truck scenes by offsetting in the lane to maintain a safe distance from other vehicles on the road and to improve comfort.

The path blocking behavior of changing lanes in dense traffic is improved. It will now keep cars farther apart in congested lanes to reduce the chance of being blocked in heavy traffic.

The lane changes in dense traffic scenes are improved by allowing higher acceleration in the alignment phase. This makes it more natural to find gaps to surpass cars that are very close to it in the adjacent driveway.

Thanks to the latest version of the lane guidance module integrated with road edge and line network, it can make the turn smoother by improving the detection consistency among lane, line and road edge prediction.

The accuracy of detecting the movement intention of other vehicles is improved. In the case of other vehicle steering, the accuracy is improved by 23%, and the probability of Autopilot mistakenly detecting the parking of the vehicle in front is reduced by 12%.

Expand the maximum trajectory optimization range to control high-curvature roads and distant vehicles more smoothly at high speed.

To improve driving behavior near a row of parked vehicles in a narrow lane, it will be more likely to deviate but remain in the lane rather than change lanes or slow down for no reason.

By better integrating vision-based positioning and rough map lane data, the operation of back-to-back lane change is improved.

A text introduction has been added to the user interface to inform FSD of the planned operation, and the visualization of the vehicle path before deceleration has been improved, with v words rendered at different opacity and speed to indicate the acceleration of deceleration, and a solid line will be drawn where the car is about to stop.

The recall rate and accuracy of target detection are improved, in which the position error of half-card is significantly reduced by 10%, the recall rate and accuracy of vehicles passing through 100 meters are increased by 3% and 7% respectively, and the recall rate of motorcycles is increased by 5%.

By improving the kinematic modeling of the object in the low-speed scene, the false offset around the object in the wide lane and near the intersection is reduced.

When FSD Beta is activated, it adjusts the position of the automatic blind spot camera to give priority to Autopilot visualization, or you can drag the camera to save the custom position.

Based on the recent recalls (# 23V085 in the United States and # 2023-063 in Canada), Tesla improved the following specific behaviors in the FSD Beta version:

1. The decision logic of passing through the intersection or parking in front of the yellow light is improved, taking into account the deceleration time required to stop, the time to enter and cross the intersection, and the distance to cross the intersection before the red light is changed. this makes the yellow light processing more natural and humanized.

two。 The longitudinal deceleration control mechanism at the stop sign intersection is improved to make the speed change process feel more intuitive and natural.

3. Tesla's speed adjustment logic when entering some speed regions is improved by allowing the detected speed limit signs to be controlled in advance. The response to the detected speed limit sign when decelerating depends on the current speed and the difference between the current speed and the speed indicated by the detected speed limit sign. Tesla will add a visual effect after the speed limit icon on the user interface to remind the driver when the speed set exceeds the detected speed limit by more than 50%. Finally, Tesla removed the option for absolute speed limit offsets in FSD Beta; only percentage-based offsets are available.

4. Improved the behavior that Tesla may continue to drive straight in the turning lane in some cases.

Tesla has been working hard to release the v11 version, which is critical because this is the first time Tesla's driving assistance system uses a single software stack to drive on highways and urban roads.

The week before last week, Elon Musk, chief executive of Tesla, said that the FSD Beta v11 version had been significantly improved, but "a small version needs to be polished before it can be launched on a large scale", which seems to be the big version he was talking about.

Of course, this version has actually been delayed for several months, and Tesla originally planned to release it around Thanksgiving last year. According to CTOnews.com, about 400000 car owners in North America currently have FSD Beta testing rights, and it is not clear when the FSD will be launched to more users or when it will be extended to more countries and regions outside North America.
