Those include current car readings such as inertial measurement unit (IMU), radar, GPS, ultrasonic sensors, wheel ticks, steering angle, and maps data. There are 8 vision cameras and 12 ultrasonic sensors. Data is fed to both FSD chips simultaneously for processing. The two chips independently form a future plan for the car - a detailed plan of what the car should do next. The two independently derived plans from both chips are then consequently sent to the safety system which compares them to ensure an agreement was reached. Once the two plans from both chips agree on the calculated plan, the car can proceed and act on that plan (i.e., operate the actuators). The drive commands are then validated and sensory information is used as feedback for ensuring the commands executed the desired operations. The full operation loop operates continuously at a high frame rate. |
