<P>PROBLEM TO BE SOLVED: To provide an awakening device for a vehicle that can suppress a decrease in driver's waking level and bring a driver into a waking state during travel of the vehicle. <P>SOLUTION: An awakening device for a vehicle includes a vibration generating part 25, a speaker 26, a camera 31, and a controller 41. The vibration generating part 25 is provided in a steering wheel 21, and can generate pseudo vibration simulating vibration transmitted to a driver D when a state of wheels rolling on a road surface becomes a specified state different from an ordinary state. The speaker 26 can generate pseudo sound simulating sound transmitted to the driver D when the rolling state of the wheels becomes the specified state. The camera 31 takes an image of an expression of the driver D, and the controller 41 monitors a waking state of the driver D based on image data by the camera 31 during travel of the vehicle. When the controller 41 detects a non-waking state (doze state) of the driver D, the controller 41 causes the vibration generating part 25 to generate the pseudo vibration and the speaker 26 to generate the pseudo sound, by which the controller 41 gives the driver D an illusion of occurrence of the specified state and brings the driver D into the waking state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
