An interactive guidance method and interactive guidance system for vehicle speed and traffic lights

Abstract

The application relates to an interactive guidance method and an interactive guidance system for vehicle speed and traffic lights, and relates to the field of automobile control. In this interactive guidance method, if it is judged that the traffic light can be passed at the speed limit of the road section, then the traffic light is passed at the speed limit of the road section; Estimate the duration of driving at the speed limit of the road segment, and obtain the estimated driving distance corresponding to multiple segments, and then determine whether the vehicle continues to drive at the speed limit of the road segment according to the remaining distance between the vehicle and the traffic light and the traffic information of the traffic light, if not, then According to the remaining distance between the vehicle and the traffic light and the passing state of the traffic light, the speed of the vehicle passing the traffic light is determined. The interactive guidance method provided by the present application solves the problem in the related art that the electric vehicle stops for a long time when encountering a traffic light, or frequently changes the vehicle speed in order to avoid reducing the waiting time, resulting in high energy consumption.

Description

technical field [0001] The present application relates to the field of automobile control, in particular to an interactive guidance method and interactive guidance system for vehicle speed and traffic lights. Background technique [0002] With the increasing coverage of road traffic, the number of cars is increasing. Correspondingly, in order to ensure the safety of driving, more and more intersections or road sections are equipped with traffic lights to ensure the orderly driving process. However, it also makes the driver frequently encounter traffic lights in the process of driving, and needs to start and stop frequently, and each start and stop consumes a relatively large amount of energy for the car, especially the electric car. [0003] In related technologies, since the current automobiles are equipped with corresponding navigation devices, in order to minimize the start and stop of the driver during driving, some navigation devices can provide the driver with a planne...
