Problems solved by technology

While the fastest route is usually desired by most drivers, drivers with sleeping passengers may be willing to delay reaching their destination if they can take a longer, more sleep-friendly, and at the same time smoother, quieter route , instead of following the fastest route
Currently, drivers have to think on their own and navigate to longer, smoother, quieter routes, and navigation devices don't help drivers easily find alternate routes while passengers are sleeping

Embodiment Construction

[0037] Please refer to figure 1 . figure 1is a block diagram of a system 10 for adjusting a navigation route based on detected passenger sleep data according to the present invention. System 10 includes one or more sleep monitoring devices 12 . The sleep monitoring device 12 generates a sleep indicator for one or more occupants seated in the vehicle. Each passenger may have its own sleep monitoring device 12 or multiple sleep monitoring devices 12 to detect the passenger's sleep activity. For simplicity, one occupant wearing the sleep monitoring device 12 will be described below, but the invention can be applied to any number of occupants whose sleep activity is being monitored. Examples of sleep monitoring devices 12 include exercise bands that detect the movement of the occupant and cameras that detect the facial movement and facial expressions of the occupant. For example: Judging by the changes in the image frame [image frame] whether the passenger is in the situation ...

Abstract

A method of adjusting a navigation route based on detected passenger sleep data includes generating a predetermined route with a device installed in a vehicle, providing navigational assistance for guiding a driver to follow the predetermined route, receiving sleep indicators for a passenger traveling in the vehicle, the sleep indicators indicating whether the passenger is sleeping, calculating a sleep session duration for the passenger according to the sleep indicators, generating with the device an alternate route in response to the sleep session duration exceeding a first time threshold, wherein the alternate route provides a longer route that requires more travel time than the predetermined route, providing navigational assistance to the driver for guiding the driver to follow the alternate route, and providing navigational assistance to the driver for guiding the driver to return to the predetermined route after the vehicle has followed the alternate route.

Description

technical field [0001] The invention relates to a navigation device, in particular to a navigation device for adjusting a navigation route when it is detected that a passenger has fallen asleep. Background technique [0002] Global Positioning System (GPS) based navigation devices are well known and widely used as in-vehicle navigation devices. Common functions of a navigation device include providing a map database to generate navigation instructions, which are then displayed on the display of the navigation device. Typically, these navigation devices are mounted on or in the vehicle's dashboard using suction cup mounts or other mounting devices. [0003] The term "navigation device" refers to a device that enables a user to navigate to a predefined destination. The device may include an internal system for receiving location data, such as a GPS receiver, or the device may be connected to a receiver capable of receiving location data. The device may calculate its own rou...
