Autonomous Cars

The module configuration of the self-driving system is like simulating a human driving a vehicle. First, humans must recognize the vehicle’s surrounding environment through their eyes and use their brains to decide the vehicle’s driving path. Finally, use their hands and feet to control the steering and braking of the vehicle.

Car, throttle, let the vehicle drive safely to the destination. The eyes of a self-driving car are sensors such as lidar, radar, and camera. The original data is analyzed through algorithms to identify the type and location of obstacles. Because different types of sensors have different resolution capabilities for obstacles, such as the camera for obstacles. The color or appearance recognition ability is strong, the lidar has a solid ability to detect the position and detection range of obstacles, and the radar has a strong detection distance ability to metal obstacles, so the characteristics of obstacles detected by the sensor are analyzed—perceptual fusion, calculating the obstacle information of the environment around the self-driving car.

After the self-driving car analyzes the environmental information, it still needs to know the location and driving destination of the self-driving car. Therefore, it is necessary to receive GPS, IMU, dynamic vehicle information, sensor environmental feature detection, and high-precision positioning through the cooperative positioning module. The self-driving car’s location and destination driving trajectory are obtained after calculating the map data. Next, the decision-making module uses the environmental information of the multi-sensory fusion module, the location of the vehicle, and the destination track of the collaborative positioning module to carry out dynamic decision-making design. It displays the information status of the self-driving car on the human-machine interface and background management.

High-resolution maps are an integral part of self-driving technology. Compared with ordinary maps, high-precision maps require more detailed information on roads, traffic signs, lane lines, obstacles, etc., and higher geolocation accuracy. This map data is the basis for self-driving sensors and positioning systems that provide more accurate location and environmental awareness. Establishing high-precision maps requires combining satellite surveying and mapping technology, ground surveying vehicles, laser scanning, and image processing technologies to collect and organize road-related information. These map data need to be updated and maintained in real-time to deal with road changes, construction sites, and traffic incidents.

Decision-making control technology is the key to realizing the intelligent driving of self-driving cars. Based on the information provided by sensors and positioning systems, self-driving cars need to be able to perform real-time path planning, obstacle identification, and traffic behavior prediction and make corresponding decisions and control actions. This involves applying artificial intelligence techniques like deep, machine, and reinforcement learning. Self-driving cars must understand and predict dynamic changes in the surrounding environment, such as other vehicles, pedestrians, traffic signals, etc., and make adaptive decisions in different situations. Decision-making control technology also needs to consider the balance of security and performance. Self-driving cars must ensure safe driving, obey traffic laws and norms, and respond appropriately when encountering danger or emergencies. At the same time, self-driving cars also need efficient driving strategies, such as reducing driving time and energy consumption.

As a self-driving vehicle, a self-driving car needs to interact well and communicate with passengers or users. Human-computer interaction technology includes voice commands, gesture recognition, face recognition, touch interface, etc., enabling passengers to conveniently communicate and operate self-driving cars. Human-computer interaction technology also involves designing interior infotainment and passenger safety monitoring systems. Self-driving cars must provide rich entertainment and information services while ensuring the safety and comfort of passengers.

The development of self-driving car technology must pay attention to safety and privacy protection. Self-driving cars need reliable security mechanisms to prevent the system from being hacked or maliciously interfered with. This includes securing the vehicle’s communications and control systems and ensuring that the vehicle’s data and operation are not tampered with or tampered with by unauthorized persons. At the same time, self-driving cars also need to protect the privacy of passengers and pedestrians. Self-driving cars usually collect and process a large amount of sensing data and location information, so strict privacy protection policies and technical measures must be formulated to ensure the security and confidentiality of personal data.
