Autonomous vehicles
Aspects of the present disclosure relate to a vehicle for maneuvering a passenger to a destination autonomously. The vehicle includes one or more computing devices and a set of user input buttons for communicating requests to stop the vehicle and to initiate a trip to the destination with the one or more computing devices. The set of user input buttons consisting essentially of a dual-purpose button and an emergency stopping button different from the dual-purpose button configured to stop the vehicle. The dual-purpose button has a first purpose for communicating a request to initiate the trip to the destination and a second purpose for communicating a request to pull the vehicle over and stop the vehicle. The vehicle has no steering wheel and no user inputs for the steering, acceleration, and deceleration of the vehicle other than the set of user input buttons.
1. A system for controlling a vehicle, the system comprising one or more processors configured to:
display a first indicator at a first user input button to indicate the availability of a first command state for the first user input button, wherein when the first user input button is in the first command state, input at the first user input button initiates an autonomous driving mode of the vehicle;
after displaying the first indicator, receive first user input at the first user input button;
in response to the first user input at the first user input button, controlling the vehicle, by one or more processors, in the autonomous driving mode;
in response to receiving the first user input at the first user input button, change the first indicator to indicate a new inactive state for the first user input button and displaying a second indicator at a second user input button to indicate the availability of a second command state;
after displaying the second indicator and receiving the first user input, receive second user input at the second user input button; and
in response to receiving the second user input, stop the vehicle.
2. The system of claim 1 , wherein the stopping the vehicle includes pulling the vehicle over to a side of a roadway and stopping movement of the vehicle.
3. The system of claim 1 , wherein the one or more processors are further configured to determine that the vehicle is ready for the autonomous driving mode, and wherein displaying the first indicator occurs after determining that the vehicle is ready for the autonomous driving mode.
4. The system of claim 3 , wherein the one or more processors are further configured to, in conjunction with changing the first indicator, change the state of the first user input button to the inactive state.
5. The system of claim 1 , wherein the one or more processors are further configured to, in conjunction with displaying the second indicator, change the state of the second user input button from an inactive state to the second command state.
6. The system of claim 1 , wherein stopping the vehicle includes bringing the vehicle to a stop within a predetermined period of time associated with the second command state.
7. The system of claim 6 , wherein the one or more processors are further configured to receive user input at a third user input button configured to communicate a request to stop the vehicle within a second predetermined period of time less than the predetermined period of time.
8. The system of claim 7 , further comprising the third use input button.
9. The system of claim 1 , wherein the one or more processors are further configured to, after receiving the second user input, change the first indicator from the new state to indicate the availability of the first command state for the user input button.
10. The system of claim 1 , wherein the second command state corresponds to pulling the vehicle over such that the second user input corresponds to a request to pull the vehicle over.
11. The system of claim 1 , wherein the one or more processors are further configured to receive information identifying a destination from a client computing device associated with a passenger, such that controlling the vehicle includes maneuvering the vehicle to the destination.
12. The system of claim 1 , further comprising the first user input button.
13. The system of claim 1 , further comprising the second user input button.
14. The system of claim 1 , further comprising the vehicle.
15. The system of claim 14 , wherein the vehicle does not have a user-controlled steering mechanism which would allow a passenger to directly control steering of the vehicle.
16. The system of claim 14 , wherein the vehicle does not have a steering wheel.
17. The system of claim 14 , wherein the vehicle does not have a user-controlled acceleration control which would allow a passenger to directly control acceleration of the vehicle.
18. The system of claim 14 , wherein the vehicle does not have an accelerator pedal.
19. The system of claim 14 , wherein the vehicle does not have a user-controlled deceleration control which would allow a passenger to directly control deceleration of the vehicle.
20. The system of claim 14 , wherein the vehicle does not have a brake pedal.
