Abstract
The present invention relates to a vehicle safe starting device which controls the starting of a vehicle according to a driver's state. One embodiment analyzes blood alcohol concentration by projecting infrared rays into the driver's skin and receiving a reflected signal, and thereafter controls so that the vehicle is not stared if the blood alcohol concentration is larger than a reference value. Since a general breathalyzer using a driver's exhalation is not used, but infrared rays and a method of skin contact touch using a finger, etc. are used, it is possible to accurately measure the blood alcohol level without giving a driver inconvenience, and it is possible to preempt vehicle accidents by blocking driving in an inappropriate state.
Claims13
A vehicle safe starting device, comprising:
- a touch part for physically contacting skin of a human;
- an optical sensor part comprising a transmitter that projects an electromagnetic wave of a predetermined frequency region to the skin of a human contacted by the touch part, and a receiver that receives a signal of the projected electromagnetic wave reflected by the skin of the human;
- and
- an analysis part that analyzes the reflective signal and outputs a start control signal as a result of the analysis;
- wherein the transmitter and the receiver are disposed in a horizontal direction that is in parallel to the touch part.
