Tesla, founded by Elon Musk, has revolutionized the world’s perception of electric vehicles. Despite facing continuous losses for nine years, Tesla still maintains a high market value. From its inception, Tesla has been in the spotlight, several times nearing bankruptcy but then successfully raising funds. This resilience and determination have made Tesla a symbol of innovation and disruption in the automotive industry.
Autonomous Driving: The Future of the Automotive Industry
Autonomous driving is a critical technological direction for the automotive industry. It integrates sensors, advanced algorithms, software ecosystems, chip hardware, map navigation, vehicle architecture, information security, laws and regulations, and other elements into a comprehensive system engineering project.
Tesla has been at the forefront of autonomous driving technology, continuously pushing the boundaries of what is possible. The company’s autonomous driving system is an integral part of its electric drive system (EDS), which is now one of the core systems of automobiles.
Evolution of Tesla’s Electric Drive System
Tesla’s electric drive system has undergone four generations of technological iterations, each bringing significant improvements and innovations.
First Generation (Roadster): This generation used an asynchronous induction motor authorized by AC Propulsion. The controller applied IGBT single-tube parallel technology. Due to its early development and limited deliveries, it has less reference significance for the current industry.
Second Generation (Model S/X): The controller was changed to a three-dimensional structure, similar to a stacked sandwich, with the asynchronous motor and controller symmetrically arranged on the left and right.
Third Generation (Model 3/Y): This generation first introduced permanent magnet synchronous motors (PMAC). The controller applied silicon carbide power devices and changed the structural design of the controller, making it more compact.
Fourth Generation: This generation optimized the protection of the output three-phase electrical connection, added an infrared temperature sensor, and changed the previously screw-fixed connectors on the controller to stir welding for integrated molding, further reducing costs.
Tesla’s Autonomous Driving Technology
Tesla’s autonomous driving technology is based on a multi-layered logical framework, incorporating various sensors, algorithms, and software to provide a safe and reliable driving experience.
Sensors: Tesla vehicles are equipped with a variety of sensors, including cameras, infrared sensors, lidar, millimeter-wave radar, ultrasonic sensors, GNSS modules, and inertial sensors. These sensors provide image information, point cloud information, distance information, position information, and attitude information, respectively.
Algorithms: The perception algorithm processes data from multiple data sources with extremely low latency to provide instant and reliable information. Mainstream implementation directions include early fusion and late fusion. Late fusion algorithms perform feature extraction on each modal information before fusion, requiring lower data and computing power but also reducing the effectiveness of information complementarity.
Multi-task Processing: Vehicles need to simultaneously process multiple tasks, such as signal recognition, detection, segmentation, fusion, target tracking, behavior prediction, planning, and decision-making. Efficient and real-time processing of multiple tasks is crucial for ensuring driving safety. Tesla’s Nine-headed Snake Network is a typical multi-task network architecture.
Multi-scale Analysis: The driving environment is complex and changing, requiring the detection and tracking of targets of various sizes. Multi-scale analysis can significantly improve the performance of the perception module in autonomous driving systems.
