US 2020/0139969 A1 · DRIVING CONTROL METHOD USING TRAFFIC LIGHT INFORMATION AND VEHICLE FOR PERFORMING THE SAME

Abstract

A method of guiding driving with low fuel efficiency using traffic light information includes: acquiring traffic light information on a forward traffic light, determining whether the vehicle is capable of passing through the forward traffic light without stopping based on the traffic light information, a current vehicle speed, and available acceleration and deceleration speeds, and when the vehicle is capable of passing through it without stopping, outputting a guidance speed for enabling the vehicle to pass through the forward traffic light without stopping. In particular, the forward traffic light information includes information on a current signal of the traffic light and information on a remaining time until the current signal is changed to another signal.

A method of controlling a vehicle, the method comprising:

acquiring, by a communication unit, traffic light information of a forward traffic light ahead of the vehicle;
determining, by a processor, whether the vehicle is capable of passing through the forward traffic light without stopping based on the traffic light information, a current vehicle speed of the vehicle, and available acceleration and deceleration speeds of the vehicle;
and
when the vehicle is capable of passing through the forward traffic light without stopping, outputting, by the processor, a guidance speed for enabling the vehicle to pass through the forward traffic light without stopping,
wherein the forward traffic light information includes at least information on a current signal of the traffic light and information on a remaining time until the current signal is changed to another signal indicating a change in a passability of the vehicle.

A vehicle comprising:

a communication unit configured to acquire traffic light information on a forward traffic light ahead of the vehicle;
a traffic signal processor configured to:
determine whether the vehicle is capable of passing through the forward traffic light without stopping based on the traffic light information, a current vehicle speed of the vehicle, and available acceleration and deceleration speeds of the vehicle, and
determine a guidance speed for enabling the vehicle to pass through the forward traffic light without stopping;
and
an outputting unit configured to output the guidance speed,
wherein the forward traffic light information includes at least information on a current signal of the traffic light and information on a remaining time until the current signal is changed to another signal indicating a change in a passability of the vehicle.
