The present invention disclosed herein relates to a signal information transmitting device and a signal information transmitting method.
A car having an Electronic Control Unit (ECU) is driven according to a control of the ECU. Exemplarily, the car may control a fuel injection amount, front wheel and rear wheel brakes, and front wheel and rear wheel driving powers according to a control of the ECU. Additionally, the car may control whether to drive the engine according to a control of the ECU. For example, when the car waits for a traffic light, the engine of the car may be stopped according to a control of the ECU. Also, when the car starts, the engine of the car may be driven according to a control of the ECU.
According to the timings that the ECU stops and drives the engine, the fuel consumption efficiency and operating performance of the car may be changed. For example, as a time until the engine stops after the car stops is longer, the fuel consumption efficiency of the car is decreased. Moreover, as a time until the engine starts after a start signal is turned on is shorter, the operating performance of the car is increased. That is, when the ECU of the car is synchronized to a signal switching timing of a traffic light, the fuel consumption efficiency and operating performance of the car may be optimized.
