Embodiment Construction

[0044] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.

[0045] In addition, the adaptive cruise control referred to in the embodiments of the present invention, that is, ACC, refers to a technology that allows the driver to automatically drive the vehicle while maintaining a safe distance from the vehicle in front, which is based on the detection of the vehicle in front by the millimeter wave radar. In the driving process of the vehicle, there are usually three situations: 1) Cruise mode, when there is no other vehicle in front of the lane, the ACC system controls the vehicle to drive at the set speed; 2) Follow mode, in the lane ahead When there are other vehicles running, if the speed of the vehicle in front is lower than the set speed of the vehicle, the ACC system will control the vehicle to maintain a set safety distance with the vehicle in front, and follow the vehicle ...

Abstract

The invention relates to the field of automatic driving and intelligent transportation, and provides a self-adaptive cruise system and control method supporting traffic light recognition. The self-adaptive cruise system comprises a wireless receiving module and a main controller, wherein the wireless receiving module is matched with a wireless transmitting module of a traffic light and used for receiving first traffic light state information, which is transmitted by the wireless transmitting module, about the traffic light on the current lane; and the main controller communicates with the wireless receiving module and is used for acquiring the first traffic light state information received by the wireless receiving module and carrying out parking control or self-adaptive cruise control based on the first traffic light state information. According to the invention, the wireless receiving module matched with the wireless transmitting module of the traffic light is additionally arranged to obtain the traffic light state information, and the self-adaptive cruise control for avoiding violation of the traffic light is further realized based on the obtained traffic light state information, so that the driving safety can be improved.

Description

technical field [0001] The invention relates to the technical fields of automatic driving and intelligent transportation, in particular to an adaptive cruise system and a control method supporting traffic light recognition. Background technique [0002] With the popularization of advanced driver assistance systems, people's driving vehicles have become safer and more convenient, and their driving behaviors have become more reasonable and standardized. Among them, as an important component of the advanced driver assistance system, the adaptive cruise control (Adaptive Cruise Control, ACC) system enables the vehicle to intelligently choose to cruise, follow or brake according to the situation of the vehicle ahead detected by the millimeter-wave radar, so as to avoid or slow down the The occurrence of car accidents. [0003] However, the existing ACC system implemented by millimeter-wave radar cannot recognize traffic lights (hereinafter referred to as traffic lights), so when...
