Abstract

The autonomously driving vehicle is fitted with a GPS unit to which a library of points of interest is assigned, and comprises a human-machine interface that is connected to the GPS unit and which comprises at least one of the following input means for the input of a command for the most immediate possible stopping of the vehicle: a unit for speech input that is connected to the interface, a module for recognizing gestures that is connected to the interface, and a touch-sensitive screen that is connected to the interface.

First claim

What is claimed is:

1. A method of controlling a vehicle comprising:
receiving a stop command from an on-board passenger via a human machine interface indicative of an intermediate destination identified by the passenger for an immediate stop and not previously communicated to the vehicle during autonomous travel of the vehicle along a route to a previously selected final destination;
identifying any stop locations within a predetermined distance of the intermediate destination based on a vehicle controller comparing data from a global positioning system (GPS) unit and a database of possible stop locations;
informing the passenger that the immediate stop is possible in response to one of the identified stop locations being within a predetermined distance of the intermediate destination;
in response to the immediate stop being possible, modifying the route to include one of the identified stop locations, autonomously driving the vehicle to the one of the identified stop locations, and stopping the vehicle on the basis of the stop command;
informing the passenger that the immediate stop is not possible in response to determining that stop locations are unavailable within the predetermined distance of the intermediate destination; and
in response to the immediate stop not being possible, maintaining autonomous travel of the vehicle along the route to the previously selected final destination.

2. The method of claim 1 wherein the stop command is received by the interface as one of a speech input, a gesture input, or input on a touch-sensitive screen.

3. The method of claim 1 further comprising receiving a signal indicative of actuation of a field on the interface by a passenger, the field actuation enabling the interface to receive the stop command.

4. The method of claim 3 wherein the interface will receive and process the stop command only subsequently to the field being actuated.

5. The method of claim 1 further comprising requesting, via the interface, a stop duration input from the passenger prior to informing the passenger that the immediate stop is possible.

6. A method comprising:
in response to receiving a command from a passenger interface indicative of a intermediate destination for a spontaneous stop during autonomous travel of a vehicle along a route to a previously selected final destination, identifying any stop locations within a predetermined distance of the intermediate destination using data from a global positioning system (GPS) unit and a stop location database;
informing the passenger that the spontaneous stop is possible in response to one of the identified stop locations being within the predetermined distance of the intermediate destination, modifying the route to include the one of the identified stop locations, and autonomously driving the vehicle to the one of the identified stop locations, and stopping the vehicle on the basis of the command; and
informing the passenger that the spontaneous stop is not possible in response to determining that any stop locations are unavailable within the predetermined distance of the intermediate destination, and maintaining autonomous travel of the vehicle along the route to the previously selected final destination.

7. The method of claim 6 further comprising requesting, via the interface, a stop duration input from the passenger prior to informing the passenger that the spontaneous stop is possible.

8. The method of claim 6 wherein the command is received by the interface as one of a speech input, a gesture input, or input on a touch-sensitive screen.

9. The method of claim 6 further comprising, enabling the interface to receive the command in response to actuation of a field on the interface by a passenger.
