Abstract

A vehicle includes an on-hoard satellite navigation device, a telematics control unit, a non-transitory computer readable medium, and a processor. The on-board satellite navigation device is in communication with a global positioning system unit to acquire real-time information regarding conditions near the vehicle's vicinity. The telematics control unit is in wireless communications to a cloud services or a vehicle network to upload and receive crowdsourced information regarding conditions near the vehicle's vicinity. The non-transitory computer readable medium stores predetermined information regarding conditions near the vehicle vicinity. The processor is programmed to output one or more complexity values related to the vehicle's vicinity during vehicle travel based on one or more of the real-time information, the crowdsourced information and the predetermined information.

Claims (14)

1 . A vehicle comprising:

an on-board satellite navigation device in communication with a global positioning system unit to acquire real-time information regarding conditions near the vehicle's vicinity;

a telematics control unit in wireless communications to a cloud services or a vehicle network to upload and receive crowdsourced information regarding conditions near the vehicle's vicinity;

a non-transitory computer readable medium storing predetermined information regarding conditions near the vehicle vicinity;

a processor programmed to output one or more complexity graphs, each of the complexity graphs having a series of complexity values that are graphed with respect to time during vehicle travel, the series of complexity values being related to the vehicle's vicinity during vehicle travel based on one or more of the real-time information, the crowdsourced information and the predetermined information, the series of complexity values of the complexity graphs being indicative of a complexity of an upcoming situation along a vehicle navigation path; and

an electronic display device positioned within an interior compartment of the vehicle, the processor being programmed to control the electronic display device to display notification data based upon the one or more of the real-time information, the crowdsourced information and the predetermined information, the notification data including the one or more complexity graphs.

2 . The vehicle according to claim 1 , wherein

the series of complexity values are based on at least one of a vehicle stopping event, a vehicle deceleration event and a lane change event.

3 . The vehicle according to claim 2 , wherein

the processor is programmed to update the one or more complexity graphs at least once per minute of vehicle travel to include at least one additional complexity value.

4 . The vehicle according to claim 3 , wherein

the processor is further programmed to upload the one or more complexity graphs to the cloud services via the telematic control unit during vehicle travel.

5 . The vehicle according to claim 4 , wherein

the processor is further programmed to receive complexity information from the cloud services or the vehicle network via the telematics control unit.
