Abstract

A vehicle can be controlled based on feedback from a driver of the vehicle when a mobile device is connected to a computer system. A profile for a driver can be used. The system can receive data about the driver from the mobile device. The data and answers can be sent to a natural language processing (NLP) system for analysis. The NLP system can return a determination that the user is cognitively disengaged, and thus unable to safely drive the vehicle. The system can then control the vehicle.

Claims

1. A computer implemented method for controlling a vehicle based on feedback from a driver of the vehicle, the method comprising:

connecting to a user device, the user device associated with the driver of the vehicle and connected to the vehicle;

accessing, based on the connecting, a profile associated with the driver of the vehicle, the profile including information regarding the driver'"'"'s medical conditions;

receiving, from the user device, data about the driver of the vehicle;

sending, to a natural language processing (NLP) system, the NLP system configured to process unstructured textual data, the data about the driver of the vehicle and the profile;

receiving, from the NLP system, a determination based on data, including unstructured textual data, that the driver is cognitively disengaged;

transfer, based on the determination, control of the vehicle to an automated control node within the vehicle;

in response to receiving the determination that the driver is cognitively disengaged, determining a severity of the driver'"'"'s cognitive disengagement;

determining, based on the severity, one or more contacts associated with the driver to contact; and

notifying the one or more contacts of the driver'"'"'s cognitive disengagement.

2. The method of claim 1, further comprising:

sending, based on the profile, prompts to the user device;

receiving, in response to the prompts, input from the user device; and

sending, to the NLP system, the input from the user device.

3. The method of claim 2 wherein the prompts comprise questions designed to test cognitive abilities of the driver.

4. The method of claim 1 further comprising:

notifying, based on the controlling, one or more contacts associated with the driver of the vehicle.

5. The method of claim 1, wherein controlling the vehicle comprises shutting off an engine of the vehicle.

6. The method of claim 1, wherein controlling the vehicle comprises initiating transfer of control of the vehicle to an automated control node in the vehicle.

7. The method of claim 1, wherein the data about the driver of the vehicle comprises data collected from sensors on the user device and from the vehicle.

8. The method of claim 1, wherein the data about the driver of the vehicle comprises historical usage data, relative to driving patterns.

9. The method of claim 1 further comprising:

receiving, in response to the controlling and from the user device, additional data about the driver of the vehicle;

sending, to the NLP system, the additional data about the driver;

receiving, from the NLP system, a determination that the driver is cognitively engaged;

initiating transfer of control of the vehicle to the driver.
