In order to ensure that EV can make correct judgments, real-time acquisition and identification of surroundings is necessary.
Context
Autonomous driving technology relies on computer and artificial intelligence technology to achieve complete, safe, and effective driving without human manipulation, representing a technology in the automotive industry. With the continuous advancement of technology, autonomous driving is poised to disrupt people’s transportation patterns and vehicle choices, a trend closely monitored by governments, automakers, suppliers, consumers, and investment institutions alike. The working principle of autonomous driving cars involves three stages: perception, decision-making, and control. To achieve autonomous driving, it is essential to prioritise addressing one issue, driving safety.
Evidence
Pending intelligence enrichment.
Analysis
In order to ensure that autonomous vehicles can make correct judgments in different scenarios, real-time dynamic acquisition and identification of surrounding environmental information is necessary. This information includes but is not limited to the vehicle’s status, traffic flow information, road conditions, and traffic signs, in order to meet the requirements of the vehicle’s decision-making system. In other words, environmental perception plays a role similar to the eyes and ears of a human driver and is a prerequisite for achieving autonomous driving. Cameras and radar are the most important sensors in the environmental perception system of autonomous driving vehicles. Cameras can directly capture images and videos, and the data can be transmitted to the central decision-making organisation through simple connections. They have high timeliness, sensitivity, and accuracy. Radar detects the position of targets through radio waves. Different radars have different functions, but their basic components are similar, mainly including the transmission system, receiving system, and processing system, as well as auxiliary systems such as power supply, display system, and anti-interference system.
Key Points
- To achieve autonomous driving, it is essential to prioritise addressing one issue, driving safety.
- The autonomous driving decision-making system is the stage where artificial intelligence shines.
- Automatic driving control technology is the core component for automobiles to automatically adjust their trajectory, change lanes, and regulate speed during operation, acting as the brain of intelligent vehicles.
Actions
Pending intelligence enrichment.
