Autonomous vehicle adapted for sleeping or resting in a reclined posture
A vehicle has an automatically tiltable seat, a plurality of seat actuators fully supporting the automatically-tiltable seat to enable the automatically tiltable seat to pitch or roll to compensate for motion of the vehicle, and a processor to predict the motion of the vehicle and to control the plurality of seat actuators. The plurality of seat actuators automatically adjust the pitch or roll of the automatically tiltable seat in response to the motion of the vehicle. The seat actuators also provide shock absorption.
1. A vehicle comprising:
an automatically tiltable seat;
a plurality of seat actuators fully supporting the automatically-tiltable seat to enable the automatically tiltable seat to pitch or roll to compensate for motion of the vehicle;
a processor to predict the motion of the vehicle and to control the plurality of seat actuators;
wherein the plurality of seat actuators automatically adjust the pitch or roll of the automatically tiltable seat in response to the motion of the vehicle; and
wherein the seat actuators also provide shock absorption.
2. The vehicle of claim 1 wherein the processor cooperates with the plurality of seat actuators to cause a yaw motion of the automatically tiltable seat.
3. The vehicle of claim 1 wherein the automatically tiltable seat comprises pneumatically inflatable bladders to further constrain a user sitting in the automatically tiltable seat.
4. The vehicle of claim 1 wherein the processor controls the plurality of seat actuators using a seat angle of the automatically tiltable seat and a mass of a user sitting in the seat by measuring the mass of the user using a weight-measuring sensor embedded in the seat.
5. The vehicle of claim 1 wherein the processor cooperates with the plurality of seat actuators to raise or lower the automatically tiltable seat.
6. The vehicle of claim 1 wherein the processor cooperates with the plurality of seat actuators to move the automatically tiltable seat forward or rearward.
7. The vehicle of claim 1 wherein the plurality of seat actuators support a platform that provides seat tracks for the automatically tiltable seat.
8. The vehicle of claim 1 wherein the plurality of seat actuators comprises six seat actuators.
9. The vehicle of claim 1 wherein the process controls the plurality of seat actuators based on the relative lag times of brakes of the vehicle and the seat actuators.
10. A vehicle comprising:
an automatically tiltable seat;
a plurality of seat actuators fully supporting the automatically-tiltable seat to enable the automatically tiltable seat to tilt at an angle to compensate for motion of the vehicle;
a processor to predict the motion of the vehicle and to control the plurality of seat actuators;
wherein the plurality of seat actuators automatically tilt the angle of the automatically tiltable seat in response to the motion of the vehicle; and
wherein the seat actuators also provide shock absorption.
11. The vehicle of claim 10 wherein the processor cooperates with the plurality of seat actuators to cause a yaw motion of the automatically tiltable seat.
12. The vehicle of claim 10 wherein the automatically tiltable seat comprises pneumatically inflatable bladders to further constrain a user sitting in the automatically tiltable seat.
13. The vehicle of claim 10 wherein the processor cooperates with the plurality of seat actuators to raise or lower the automatically tiltable seat and to also move the automatically tiltable seat forward or rearward.
14. A vehicle comprising:
an automatically tiltable seat;
a plurality of seat actuators fully supporting the automatically-tiltable seat to enable the automatically tiltable seat to pitch or roll to compensate for motion of the vehicle;
a processor to predict the motion of the vehicle and to control the plurality of seat actuators; and
wherein the plurality of seat actuators automatically adjust the pitch or roll of the automatically tiltable seat in response to the motion of the vehicle.
15. The vehicle of claim 14 wherein the processor cooperates with the plurality of seat actuators to cause a yaw motion of the automatically tiltable seat.
16. The vehicle of claim 14 wherein the automatically tiltable seat comprises pneumatically inflatable bladders to further constrain a user sitting in the automatically tiltable seat.
17. The vehicle of claim 14 wherein the processor cooperates with the plurality of seat actuators to raise or lower the automatically tiltable seat.
18. The vehicle of claim 14 wherein the processor cooperates with the plurality of seat actuators to move the automatically tiltable seat forward or rearward.
19. The vehicle of claim 14 wherein the seat actuators also provide shock absorption.
20. The vehicle of claim 14 wherein the processor controls the seat actuators based on a predicted incline of the road.
