Vehicle speed and traffic light interactive guiding method and interactive guiding system

Abstract

The invention relates to a vehicle speed and traffic light interactive guiding method and interactive guiding system and relates to the field of vehicle control. According to the interactive guiding method, if it is judged that a vehicle can pass a traffic light at a road-section limited speed, the vehicle can pass the traffic light at the road-section limited speed; if it is judged that the vehicle cannot pass the traffic light traffic light at the road-section limited speed, a duration in which the vehicle can pass through the traffic light at the road-section limited speed is estimated for multiple times in a successive approximation mode according to related information, a plurality of sections of corresponding estimated driving distances are acquired;whether the vehicle continues to run at the road-section limited speed is determined according to the remaining distance between the vehicle and the traffic light and the traffic information of the traffic light; and if the vehicle does not continue to run at the road-section limited speed, the speed of the vehicle passing through the traffic light is determined according to the remaining distance between the vehicle and the traffic light and the traffic state of the traffic light. According to the interactive guiding method provided by the invention, the problem that the parking time of the electric vehicle is long when the electric vehicle encounters the traffic light or the energy consumption is relatively high due to frequent vehicle speed change in order to avoid reducing the waiting time in the prior art is solved.

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...
