Red light avoidance system

Abstract

The invention provides a red light avoidance system. The red light avoidance system comprises a smart phone where a red light application program is installed and an automobile with a speed control module. The automobile automatically runs according to an optimum vehicle speed so as to avoid a red light. The red light avoidance system can save energy and reduce pollution and does not influence running safety. A universal device (such as the smart phone) rather than a customized device is adopted for the red light avoidance system to achieve the goal of red light avoidance. An existing traffic control system and an existing vehicle-mounted electronic device do not need to undergo too much modification. Therefore, the red light avoidance system is very low in hardware cost.

Description

technical field [0001] The present invention relates to the field of electronic equipment, more specifically, relates to vehicle-mounted electronic equipment. Background technique [0002] Traffic lights (signal lights) control the flow of vehicles at intersections. Because the phase of the signal light is not known in advance, drivers often encounter red lights and are forced to brake. Frequent braking wastes the car's kinetic energy, which increases fuel consumption, and it also has a negative impact on the environment. In order to save energy and improve the environment, it is hoped to develop a system that avoids red lights. [0003] US Patent 6,989,766 (inventor: Mese et al., grant date: January 24, 2006) proposes a system for avoiding red lights. It includes a GPS to track the vehicle's position and a receiver to receive time information for the next traffic light. The system calculates the optimal speed to avoid red lights and displays this to the driver, who chan...
