Method for enabling car to accurately respond to traffic lights

Abstract

The invention discloses a method for enabling a car to accurately respond to traffic lights. The method for enabling the car to accurately respond to the traffic lights comprises the following steps that a wireless transmission device is arranged in front of the traffic lights and is connected to the traffic lights, the remaining time of a current green light of the traffic lights is transmitted to the wireless transmission device, a chassis of the car is provided with a wireless receiving device which is used for receiving the remaining time that the green light turns to a red light of the wireless transmission device, the wireless receiving device transmits the information of the remaining time that the green light turns to the red light to a driving computer, the driving computer calculates the driving time that the car reaches the traffic lights according to the current car speed and a preset distance, and simultaneously displays the remaining time and the driving time on a displayer inside the car, and the driver judges according to the driving time and the remaining time to choose to accelerate to pass the green light, or keep the speed to pass the green light or slow down to wait for the next green light.

Description

technical field [0001] The invention relates to an automobile safety device, in particular to a method for an automobile to accurately respond to a traffic light, and belongs to the field of automobiles. Background technique [0002] Existing traffic light systems only display the current status of green, yellow, and red lights. For example, when the current light is green and a moving car is approaching the traffic light, the driver cannot judge whether the car can pass before the next turn of the light. Pass the green light because the remaining time cannot be known. At present, the traffic light systems in major and medium-sized cities refer to the time display, and the traffic lights display the color status of the current light and its remaining time at the same time, but there will be such a problem. Pass the traffic light before running out, so within a certain distance close to the position of the traffic light, continue to maintain the speed or even accelerate the ...

At present, the traffic light systems in major and medium-sized cities refer to the time display, and the traffic lights display the color status of the current light and its remaining time at the same time, but there will be such a problem. Pass the traffic light before running out, so within a certain distance close to the position of the traffic light, continue to maintain the speed or even accelerate the intention to pass the traffic light, but when the estimation is wrong and the actual time spent passing the distance exceeds the remaining time, in most cases , the car cannot brake in time, resulting in the illegal consequences of running a yellow light or a red light, and even the danger of causing a traffic accident
