Apparatus and method for detecting driver status

Abstract

The invention provides an apparatus and method for detecting a driver status. The apparatus for detecting a driver status may include an information acquisition unit (10) acquiring driver's vehicle driving information, driver's vehicle operation information, and driver status information, a calculation unit (20) calculating a driving load indicated by converting a factor obstructing safe driving into a numerical value, based on the information acquired by the information acquisition unit (10), a determination unit (30) determining the driving load calculated by the calculation unit (20) and comparing the driving load with a preset load margin, and a warning unit (40) warning the driver when the determination unit (30) determines that the calculated driving load exceeds the preset load margin. The apparatus and method for detecting a driver status determine whether a driver is driving safely by knowing mental and physical states of the driver, and guide, if determining that the driver is not in a safe driving state, the diver to drive safely by displaying warning, giving warning sound, reminding the driver by vibration, forcibly controlling the vehicle or other methods so as to protect the driver.

Description

technical field [0001] The present invention relates to a driver's state sensing device and its method. More specifically, the driver's state sensing device and its method are to understand the driver's mental and physical state related to driving or operating a vehicle, and to judge whether the driver is driving safely. When it is judged that the state is not safe driving, various methods are used to induce safe driving to protect the driver. Background technique [0002] Generally speaking, automobiles provide human beings with the convenience of movement and the efficiency of time. However, if the driver does not pay attention, not only the driver but also the people around him may cause harm, so more attention should be paid when using the automobile. In particular, with the recent integration of automobiles and ICT (Information&Communication Technology, information and communication technology), vehicles have gradually become intelligent and advanced. Based on this, the...

Problems solved by technology

However, there are many situations where it is difficult to visually and audibly recognize the system that warns the driver using a dot display device or a voice reminder, depending on the situation where the driver is drowned by noise while driving at high speed, or the driver is focused on driving ahead or is driving fatigued. Knowing the mental and physical state of the driver is also an important factor in driving, but it is impossible to know whether the driver has seizures or abnormal emotions, dyspnea, inattentiveness, drowsiness, anxiety, etc. with the existing technology. The problem of the state, even if this problem occurs, there is no corresponding method, so it is not enough to protect the driver
