Abstract

A computer-implemented method for dynamic vehicle control affecting sleep states of vehicle occupants includes connecting a wearable computing device associated with a vehicle occupant to a vehicle, and determining a state of the vehicle occupant based on physiological data received from at least one of the wearable computing device and the vehicle. The method includes determining a target sleep state of the vehicle occupant based on at least one of the state of the vehicle occupant, the physiological data and vehicle system data, and controlling a vehicle system of the vehicle based on the state of the vehicle occupant in relation to the target sleep state. The method includes monitoring the state of the vehicle occupant including monitoring the physiological data of the vehicle occupant in response to controlling the vehicle system and controlling the vehicle system according to the monitoring in relation to the target sleep state.

First claim

1 . A computer-implemented method for dynamic vehicle control affecting sleep states of vehicle occupants, comprising:
connecting a wearable computing device associated with a vehicle occupant to a vehicle; determining a state of the vehicle occupant based on physiological data received from at least one of the wearable computing device and the vehicle; determining a target sleep state of the vehicle occupant based on at least one of the state of the vehicle occupant, the physiological data and vehicle system data; controlling a vehicle system of the vehicle based on the state of the vehicle occupant in relation to the target sleep state; monitoring the state of the vehicle occupant including monitoring the physiological data of the vehicle occupant in response to controlling the vehicle system and controlling the vehicle system according to the monitoring in relation to the target sleep state.

2 . The computer-implemented method of claim 1 , further including determining a vehicle occupant type of the vehicle occupant, wherein the vehicle occupant type is at least one of an adult, a teen, a child, an infant, and a pet.

3 . The computer-implemented method of claim 2 , further including determining one or more physical characteristics of the vehicle occupant based on at least one of the physiological data and a vehicle occupant profile.

4 . The computer-implemented method of claim 3 , wherein controlling the vehicle system is based on the vehicle occupant type and one or more physical characteristics of the vehicle occupant.

5 . The computer-implemented method of claim 1 , wherein the target sleep state is an increased state of sleepiness in relation to the state of the vehicle occupant and wherein controlling the vehicle system based on the sleep state in relation to the target sleep state induces the increased state of sleepiness.

6 . The computer-implemented method of claim 1 , wherein the target sleep state is based on a length of a vehicle trip received from the vehicle, wherein the value of the target sleep state is a function of the length of the vehicle trip.

7 . The computer-implemented method of claim 1 , wherein monitoring the state of the vehicle occupant further includes determining an updated state of the vehicle occupant.

8 . The computer-implemented method of claim 1 , wherein monitoring the state of the vehicle occupant further includes determining a positive or negative effect on the state of the vehicle occupant in relation to the target sleep state.

9 . The computer-implemented method of claim 8 , wherein upon determining a negative effect on the state of the vehicle occupant in relation to the target sleep state, controlling the vehicle system further includes controlling a different vehicle system.

10 . A system for dynamic vehicle control affecting sleep states of vehicle occupants, comprising:
a wearable computing device associated with a vehicle occupant; a vehicle including a vehicle system, vehicle sensors and a processor, the processor operably connected for computer communication to the wearable computing device; a state determination module of the processor determines a state of the vehicle occupant based on physiological data received from at least one of the wearable computing device and the vehicle, the state determination module determines a target sleep state of the vehicle occupant based on at least one of the state of the vehicle occupant, the physiological data and vehicle system data; a vehicle control module of the processor controls the vehicle system based on the state of the vehicle occupant in relation to the target sleep state; and a state monitoring module of the processor monitors the state of the vehicle occupant including monitoring the physiological data of the vehicle occupant in response to controlling the vehicle system and the vehicle control module controls the vehicle system according to the monitoring in relation to the target sleep state.

11 . The system of claim 10 , wherein the vehicle system includes a passenger detection system, and wherein the state determination module determines a vehicle occupant type of the vehicle occupant based on vehicle data from the passenger detection system.

12 . The system of claim 11 , wherein the vehicle control module controls the vehicle system based on the vehicle occupant type and the state of the vehicle occupant in relation to the target sleep state.

13 . The system of claim 10 , wherein the state determination module determines the target sleep state as an increased state of sleepiness in relation to the state of the vehicle occupant.

14 . The system of claim 10 , wherein the vehicle system is a vehicle suspension system and the vehicle control module controls a parameter of the vehicle suspension system in relation to the vehicle occupant to induce the target sleep state.

15 . The system of claim 10 , wherein the vehicle system is a vehicle seat configuration system and the vehicle control module controls a parameter of the vehicle seat configuration system in relation to the vehicle occupant to induce the target sleep state.

16 . The system of claim 15 , wherein a parameter of the vehicle seat configuration system is a firmness of the vehicle seat occupied by the vehicle occupant.

17 . A non-transitory computer-readable storage medium storing instructions that, when executed by a computer, causes the computer to perform a method, comprising:
connecting a wearable computing device associated with a vehicle occupant to a vehicle; receiving physiological data associated with the vehicle occupant from at least one of the wearable computing device and the vehicle, and receiving vehicle system data from the vehicle; determining a state of the vehicle occupant based on the physiological data and determining a target sleep state based on at least one of the state of the vehicle occupant, the physiological data and vehicle system data; transmitting a vehicle control command to a vehicle system of the vehicle based on the state of the vehicle occupant in relation to the target sleep state; monitoring the physiological data of the vehicle occupant in response to controlling the vehicle system and transmitting a second vehicle control command to the vehicle system in response to the monitoring, the second vehicle control command based on the monitoring in relation to the target sleep state.

18 . The non-transitory computer-readable storage medium of claim 17 , further including determining the vehicle control command based on the state of the vehicle occupant and vehicle data in relation to the target sleep state.

19 . The non-transitory computer-readable storage medium of claim 17 , wherein the targets sleep state is an increased state of sleepiness in relation to the state of the vehicle occupant.

20 . The non-transitory computer-readable storage medium of claim 17 , wherein monitoring the physiological data of the vehicle occupant further includes determining a positive or negative effect on the state of the vehicle occupant in relation to the target sleep state and determining the second vehicle control command based on the determination of the positive or negative effect.
