Abstract

Vehicles feature various forms of automated driving control, such as speed control and braking distance monitoring. However, the parameters of automated control may conflict with the user driving behaviors of the user; e.g., braking distance maintained with respect to a leading vehicle may seem overcautious to users who prefer shorter braking distances, and unsafe to users who prefer longer braking distances. Presented herein are techniques for controlling vehicles according to the user driving behaviors of users. While a user operates a vehicle in a driving context, a device monitors various driving features (e.g., acceleration or braking) to determine various user driving behaviors. When requested to control a driving feature of the vehicle, a controller may identify the user driving behaviors of the user in the driving context, and control the driving features according to the user driving behaviors, thus personalizing automated driving to the preferences of the user.

First claim

What is claimed is:

1. A method of configuring a device to control a vehicle operated by a first user, the method comprising:
executing on the device instructions configured to:
while the vehicle is in operation by the first user:
monitor the operation of the vehicle by the first user to detect at least one user driving behavior of the first user for at least one driving feature of the vehicle in a first driving context to develop a first portion of a first driving profile for the first user; and
monitor the operation of the vehicle by the first user to detect at least one user driving behavior of the first user for at least one driving feature of the vehicle in a second driving context to develop a second portion of the first driving profile for the first user; and

upon receiving a request to control at least one driving feature of the vehicle in a driving context:
determine whether the vehicle is being controlled by the first user or a second user different than the first user;
determine whether the driving context is the first driving context or the second driving context;
when the driving context is the first driving context and the vehicle is being controlled by the first user:
identify the at least one user driving behavior of the first user for the at least one driving feature of the vehicle in the first driving context based upon the first driving profile; and
control the at least one driving feature of the vehicle according to the at least one user driving behavior of the first user for the at least one driving feature of the vehicle in the first driving context;

when the driving context is the second driving context and the vehicle is being controlled by the first user:
identify the at least one user driving behavior of the first user for the at least one driving feature of the vehicle in the second driving context based upon the first driving profile; and
control the at least one driving feature of the vehicle according to the at least one user driving behavior of the first user for the at least one driving feature of the vehicle in the second driving context, wherein the at least one driving feature is controlled differently based upon whether the driving context is the first driving context or the second driving context;

when the vehicle is being controlled by the second user, use a second driving profile for the second user to control one or more driving features of the vehicle when the second driving profile for the second user exists; and
when the vehicle is being controlled by the second user and no driving profile exists for the second user:
compare driving behaviors of the second user to driving behavior models created based upon driving behaviors of a plurality of users to identify a driving behavior model for the second user; and
use the driving behavior model to control the at least one driving feature of the vehicle.

2. The method of claim 1 , wherein the at least one driving feature is selected from a driving feature set comprising:
a velocity of the vehicle in a driving context;
an acceleration of the vehicle in a driving context;
a maintained distance of the vehicle with respect to at least one other vehicle in a driving context;
a lane change frequency of the vehicle between at least two lanes in a driving context;
a refueling threshold of the vehicle in a driving context; and
a routing criterion of a route of the vehicle in a driving context.

3. The method of claim 1 , wherein the driving context is selected from a driving context set comprising:
a vehicle causeway type context;
a vehicle type context;
a vehicle condition context;
a traffic congestion context;
a vehicle speed of at least one other vehicle operating near the vehicle;
a weather context;
a time of day context; and
a vehicle passenger context.

4. The method of claim 1 , wherein the instructions are further configured to detect the driving context by receiving at least one driving context descriptor from a driving context service.

5. The method of claim 1 , wherein:
the instructions are further configured to:
upon detecting a user operating the vehicle, determine an identity of the user; and
upon detecting a user driving behavior of the user of the vehicle, store the user driving behavior associated with the identity of the user.

6. The method of claim 5 , wherein the determining whether the vehicle is being controlled by the first user or a second user different than the first user comprises:
identifying an identity of a current user according to a user identifying feature selected from a user identifying feature set comprising:
an identification credential provided by the current user;
a biometric measurement of the current user;
a vehicle control input initiated by the current user for the vehicle in a current travel context; and
a user driving behavior of the current user for a driving feature of the vehicle in a driving context.

7. The method of claim 1 , wherein:
the vehicle is operated by the first user in one of at least two user contexts;
the instructions are further configured to:
upon detecting the first user operating the vehicle, determine a user context of the first user in the first driving context; and
upon detecting at least one user driving behavior of the first user of the vehicle, store the at least one user driving behavior associated with the user context of the first user;

the determining whether the driving context is the first driving context or the second driving context comprises identifying a current user context of the first user; and
the instructions are further configured to:
when the driving context is the first driving context and the vehicle is being controlled by the first user:
identify the at least one user driving behavior associated with the current user context of the first user for the at least one driving feature of the vehicle in the first driving context.

8. The method of claim 7 , wherein the identifying the current user context of the first user comprises:
identifying the current user context of the first user according to a user context identifying feature set comprising:
a user context specified by the first user;
a biometric identifier of the first user;
an interior vehicle control request initiated by the first user;
a vehicle control input initiated by the first user for the vehicle in a current travel context; and
a user driving behavior of the first user for a driving feature of the vehicle in a driving context.

9. The method of claim 1 , wherein, when the driving context is the first driving context and the vehicle is being controlled by the first user, the controlling the at least one driving feature further comprises:
controlling the at least one driving feature of the vehicle according to the at least one user driving behavior of the first user and at least one user interest indicated by the first user.

10. The method of claim 9 , wherein the at least one user interest of the first user is selected from a user interest set comprising:
a time conserving user interest;
a time predictability promoting user interest;
a toll reduction user interest;
a fuel economizing user interest;
a vehicle maintenance reducing user interest;
an emission reducing user interest;
a driving safety promoting user interest; and
a smooth driving experience promoting user interest.

11. The method of claim 1 , wherein the detecting the at least one user driving behavior comprises:
comparing at least one vehicle control input initiated by the first user with at least one user driving behavior model; and
determining the at least one user driving behavior of the first
