Driver assistance system and driver assistance method
The driver assistance system comprises a detector, a navigator, a stimulator, and a voice interactor. The detector detects wakefulness reduction of a driver or absent-minded driving by the driver. The navigator navigates a vehicle based on map information. The stimulator continuously or intermittently applies stimulation to the driver. The voice interactor interacts with the driver by voice. The navigator searches for a resting facility on a route from the map information in response to a detection of the wakefulness reduction or the absent-minded driving. The voice interactor executes a first interaction of proposing navigation to the resting facility by the navigator in response to the detection of the wakefulness reduction or the absent-minded driving, and executes a second interaction of proposing application of stimulation by the stimulator after an execution of the first interaction and during a period until the vehicle arrives at the resting facility.
1. A driver assistance system comprising:
a navigation device configured to automatically navigate a vehicle based on map information and to search for a resting facility on a route from the map information; and
a voice interaction device configured to automatically determine whether a predetermined condition exists, and when the predetermined condition exists, to automatically interact with a driver by voice and to execute a first interaction of proposing navigation to the resting facility by the navigation device, and
a stimulation device configured to continuously or intermittently apply stimulation to the driver,
wherein the voice interaction device is configured to refrain from executing the first interaction when a traffic jam occurs in a section to the resting facility;
wherein the voice interaction device is configured to execute a second interaction of proposing application of stimulation by the stimulation device; and
wherein the stimulation device is configured to apply vibration stimulation to the driver.
2. The driver assistance system according to claim 1 , wherein the voice interaction device is configured to propose application of a plurality of types of stimulation to the driver in the second interaction.
3. The driver assistance system according to claim 1 , wherein the stimulation device is configured to apply informational stimulation to the driver.
4. A driver assistance method, comprising:
automatically navigating a vehicle based on map information,
searching for a resting facility on a route from map information;
automatically determine whether a predetermined condition exists, and when the predetermined condition exists, automatically executing a first interaction by voice with a driver to propose navigation to the resting facility;
refraining from executing the first interaction when a traffic jam occurs in a section to the resting facility;
proposing application of stimulation by a stimulation device; and
applying vibration stimulation to the driver by the stimulation device.
