1. An adaptive cruise control system supporting traffic light recognition, comprising:
a wireless receiver adaptive with a wireless transmitter of each traffic light on a current lane, and configured to receive first traffic light state information about the traffic light on the lane sent by the wireless transmitter; and
a main controller being in communication with the wireless receiver and configured to obtain the first traffic light state information received from the wireless receiver and obtain information of a turn signal lamp of a vehicle through a perceptual component, and perform a stop control or adaptive cruise control on the vehicle based on the first traffic light state information and the information of the turn signal lamp;
the adaptive cruise control system further comprises:
a camera being in communication with the main controller and configured to obtain second traffic light state information about the traffic light on the current lane, and send the second traffic light state information to the main controller, wherein the camera is configured to obtain an indication direction of a ground guide arrow through image photographing and image recognition and integrate information about the indication direction of the ground guide arrow into the second traffic light state information;
wherein the main controller is further configured to perform the stop control or the adaptive cruise control on the vehicle based on the second traffic light state information and the information of the turn signal lamp.
