Abstract

A system for causing a vibration within a vehicle to change a degree of somnolence of an occupant of the vehicle can include a processor and a memory. The memory can store an occupant age discrimination and a controller module. The occupant age discrimination can include instructions that, when executed by the processor, cause the processor to determine that the occupant of the vehicle is a child. The controller module can include instructions that, when executed by the processor, cause the processor to cause, in response to a determination that the occupant is the child, the vehicle to move in a manner to induce the vibration within the vehicle to change the degree of somnolence of the occupant from an undesired state, of the degree of somnolence, to a desired state of the degree of somnolence.

2 . The system of claim 1 , wherein the memory further stores a state determination module, the state determination module including instructions that, when executed by the processor, cause the processor to:

receive, from a sensor, information related to the degree of somnolence of the first occupant; and

determine, based on the information, the degree of somnolence of the first occupant.

3 . The system of claim 2 , wherein the instructions to determine, based on the information, the degree of somnolence of the first occupant include instructions to process, with a machine learning system, the information.

4 . The system of claim 3 , wherein the memory further stores a training module, the training module including instructions that, when executed by the processor, cause the processor to train the machine learning system with training data that include at least one of known corresponding information associated with the undesired state or known corresponding information associated with the desired state.

5 . The system of claim 4 , wherein:

the first occupant is a specific occupant, and

the at least one of:

the known corresponding information associated with the undesired state or

the known corresponding information associated with the desired state comprises at least one of:

known corresponding information associated with the undesired state of the specific occupant or

known corresponding information associated with the desired state of the specific occupant.

6 . The system of claim 1 , wherein the instructions to cause the vehicle to move in the manner to induce the vibration include instructions to cause the vehicle to move in the manner to induce the vibration so that a measure of the vibration is greater than a first threshold vibration.

7 . The system of claim 6 , wherein:

the first occupant is a first specific occupant, and

the first threshold vibration is a threshold vibration associated with the first specific occupant.

8 . The system of claim 7 , wherein:

the measure of the vibration is less than a second threshold vibration,

the second threshold vibration is a threshold vibration associated with a second specific occupant of the vehicle, and

a measure of the vibration greater than the second threshold vibration is associated with an undesired state of the second specific occupant.

9 . The system of claim 1 , wherein:

the instructions to cause the vehicle to move in the manner to induce the vibration include instructions to cause the vehicle to move in a manner to induce the vibration in the direction along the lateral axis of the vehicle.

10 . The system of claim 9 , wherein the instructions to cause the vehicle to move in the manner to induce the vibration in the direction along the lateral axis of the vehicle include instructions to control the steering mechanism of the vehicle to change a degree of variation of a lateral position of the vehicle within a lane.

11 . The system of claim 1 , wherein:

the instructions to cause the vehicle to move in the manner to induce the vibration include instructions to cause the vehicle to move in a manner to induce the vibration in the direction along the vertical axis of the vehicle.

14 . The system of claim 13 , wherein the instructions to cause the vehicle to move in the manner to induce the vibration in the direction along the vertical axis of the vehicle include instructions to control a trajectory of the vehicle to cause the vehicle to traverse within a first lane rather than within a second lane, a measure of a roughness of a surface of a road in the first lane being greater than a measure of the roughness of the surface of the road in the second lane.

15 . The system of claim 14 , wherein the memory further stores a surface roughness determination module, the surface roughness determination module including instructions that, when executed by the processor, cause the processor to determine information about the measure of the roughness of the surface of the road in the first lane and the measure of the roughness of the surface of the road in the second lane.

16 . The system of claim 15 , wherein the instructions to determine the information include at least one of:

instructions to determine the information from information included in a high definition map,

instructions to determine the information from readings from a lidar device, or

instructions to determine the information from data produced by an inertial motion unit.

17 .
