What do collision warning and autonomous emergency braking mean respectively?

[DylanLee]

Collision warning is an alert triggered when the vehicle is about to be involved in a collision. Common scenarios for collision warning include sudden lane changes by vehicles ahead or abrupt shortening of distance with the preceding vehicle. Autonomous emergency braking refers to the vehicle automatically applying the brakes when it detects an obstacle ahead that poses a threat to safe driving. This function can assist drivers in avoiding major traffic accidents such as high-speed or low-speed rear-end collisions, unconscious lane departures at high speeds, and collisions with pedestrians. Both belong to active safety systems, operating on the principle of detecting data through ultrasonic, laser, infrared, or microwave methods, and making judgments based on analysis by the vehicle's computer.
