[0041] introduction

[0042] figure 1 An exemplary traffic light control system 100 is shown. Central traffic light 130 controller 140 includes a processor and memory storing instructions such that the processor is programmed for various operations including those described herein. For example, the central controller 140 may receive information from the intersection 201 (see figure 2 ) in the vicinity (ie, within a predetermined distance) of the plurality of vehicles 110 receive data indicating the kinetic energy and time of the vehicle 110 to the intersection 201 . Additionally, the controller 140 may optimize the timing of the traffic lights 130 based on the kinetic energy and time to the intersection 201 and may modify the timing of the traffic lights 130 according to the optimized timing.

[0043] Optimizing traffic light timing may include minimizing the total kinetic energy loss required due to the speed change of vehicle 110 at traffic light 130 when the signal ligh...

Abstract

Data indicative of kinetic energy and time to the intersection is received from each of the plurality of vehicles in the vicinity of the intersection. The optimal timing of the traffic lights is determined based on the set of kinetic energies and times to the intersection. The timing of the traffic lights is modified according to the optimized timing.

Description

technical field [0001] The present invention relates to the field of vehicle technology, and more particularly, to traffic light control for fuel efficiency. Background technique [0002] Traffic lights may cause the vehicle to slow down and accelerate depending on the status of the traffic lights. Deceleration, acceleration and idling of a vehicle at or near traffic lights can increase vehicle energy consumption. Contents of the invention [0003] According to the present invention, a method is provided, comprising: [0004] receiving data indicative of kinetic energy and time to the intersection from each of the plurality of vehicles in the vicinity of the intersection; [0005] determining optimal timing of traffic lights based on the aggregate of kinetic energy and time to the intersection; and [0006] Modify the timing of traffic lights according to the optimized timing. [0007] According to an embodiment of the present invention, modifying the timing of the tra...
