VEHICLE DRIVING CONTROL SYSTEM.
[0018] The external environment recognition device 10 recognizes an external environment around a vehicle (own vehicle) in which the driving control system 1 is installed. The external environment recognition device 10 includes various devices configured to recognize an environment, such as a camera unit 11 and a radar device 12 such as a millimeter wave radar or a laser radar. The external environment recognition device 10 recognizes an external environment around the own vehicle based on detection information on objects around the own vehicle detected by the camera unit 11, the radar device 12, etc., traffic information acquired by infrastructure communication such as road-to-vehicle communication and vehicle-to-vehicle communication, position information of the own vehicle measured by the positioning device 20, map information from the map information processing device 30 and the like.
[0028] The driver monitoring device 40 functions as a driver monitor configured to monitor, as a driver, an occupant who is capable of performing a driving operation in a vehicle compartment, with respect to the automatic driving control device 100. The driver monitoring device 40 detects a driver state, and transmits the detected driver state to the automatic driving control device 100. The driver state includes the driver's wakefulness level and physical condition, a motion associated with a driver's driving operation, and the like. The driver state is detected by a plurality of sensors such as a visual sensor 41, a biological sensor 42, and a cancel switch 43 for canceling the retreat mode to be described later, which are installed in the vehicle. A camera, a near infrared LED, a radar, an ultrasonic sensor, or the like installed in the vehicle is used as the visual sensor 41. A camera, a near infrared LED, a radar, an ultrasonic sensor, a temperature sensor, a vibration sensor, or the like is used as the biological sensor 42.
[0029] The driver monitoring device 40 detects a driver's facial expression, a driver's hand motion, etc., by the visual sensor 41, and also detects biological information such as the presence or absence of driver's breathing, heart rate, blood pressure, body temperature, and brain waves. As described later, the automatic driving control device 100 determines, based on information from the driver monitoring device 40, whether the driver is in a state capable of driving normally.
