Intelligent vehicle technology differs from the commonly referred to autonomous driving technology. It refers to the autonomous driving of vehicles achieved by utilizing multiple sensors and intelligent highway technology.
What are the components of an intelligent car?
Intelligent vehicles are ordinary vehicles with the addition of advanced sensors (such as radar, cameras, etc.), controllers, actuators, and other devices. Through onboard environmental perception systems and information terminals, they can exchange information with people, vehicles, roads, etc., enabling the vehicle to have intelligent environmental perception capabilities, automatically analyze the safety and danger status of the vehicle, and reach the destination according to the driver's wishes, ultimately achieving the goal of replacing human operation.
1. Navigation Information Database: A database containing information on national expressways, ordinary roads, urban roads, and various service facilities (restaurants, hotels, gas stations, attractions, parking lots).
2. GPS positioning system: (1) accurately locates the vehicle's position; (2) compares the location with data in the road database; (3) determines the future driving direction.
3. Road Condition Information System: The traffic management center provides real-time information on road conditions ahead, such as traffic jams and accidents, and allows for timely changes to travel routes when necessary.
4. Vehicle collision avoidance system: including detection radar, information processing system, driving control system, controls the distance to other vehicles, slows down or brakes in time when obstacles are detected, and transmits information to the command center and other vehicles.
5. Emergency Alarm System: In the event of an accident, it will automatically report to the command center for rescue.
6. Wireless communication system: used for communication between the vehicle and the command center.
7. Automatic driving system: Used to control the car's ignition, speed, and steering.
Intelligent vehicles are comprehensive systems integrating environmental perception, planning and decision-making, and multi-level assisted driving functions. They utilize technologies such as computers, modern sensing, information fusion, communication, artificial intelligence, and automatic control, making them typical high-tech complexes. Research on intelligent vehicles primarily focuses on improving vehicle safety and comfort, as well as providing superior human-vehicle interaction interfaces. In recent years, intelligent vehicles have become a research hotspot in the global vehicle engineering field and a new driving force for the growth of the automotive industry. Many developed countries have incorporated them into their key intelligent transportation systems development programs.
