Abstract
The present disclosure is directed to systems and methods avoiding collisions by monitoring the presence and alertness of a person in a vehicle. The alertness of that person may be monitored by identifying actions performed by that person when an automated driving assistant is used in a vehicle. Systems and method consistent with the present disclosure may monitor the alertness of a person that is located in a driving position of a vehicle according to criteria associated with particular individuals or with criteria associated with specific protocols. When a system or method consistent with the present disclosure identifies that a person is not alert, a corrective action may be initiated that reduces likelihood of a collision.
Claims22
A method for monitoring driver behavior, the method comprising:
- storing one or more driver profiles in memory, wherein each driver profile specifies a set of behavioral risk factors specific to each different driver;
- receiving sensor data from one or more sensors in a vehicle when an automated driving assistant is operating, wherein at least part of the sensor data concerns one or more inputs to one or more vehicle controls of the vehicle by a current driver in the vehicle that adjust positioning of the vehicle in a roadway lane to correct one or more variations of the vehicle from a center of the roadway lane;
- retrieving a driver profile specific to the current driver;
- identifying that a periodicity of the one or more variations from the center of the roadway lane corresponds to the one or more inputs to the one or more vehicle controls that adjust the positioning of the vehicle in the roadway lane;
- analyzing the received sensor data to identify that the current driver of the vehicle is exhibiting risky behavior based on the periodicity exceeding a periodicity threshold associated with the driver profile;
- and
- performing a corrective action based on the identification that the current driver of the vehicle is exhibiting the risky behavior.
A non-transitory computer-readable storage medium having embodied thereon a program executable by a processor for implementing a method for monitoring driver behavior, the method comprising:
- storing one or more driver profiles in memory, wherein each driver profile specifies a set of behavioral risk factors specific to each different driver;
- receiving sensor data from one or more sensors in a vehicle when an automated driving assistant is operating, wherein at least part of the sensor data concerns one or more inputs to one or more vehicle controls of the vehicle by a current driver in the vehicle that adjust positioning of the vehicle in a roadway lane to correct one or more variations of the vehicle from a center of the roadway lane;
- retrieving a driver profile specific to the current driver;
- identifying that a periodicity of the one or more variations from the center of the roadway lane corresponds to the one or more inputs to the one or more vehicle controls that adjust the positioning of the vehicle in the roadway lane;
- analyzing the received sensor data to identify that the current driver of the vehicle is exhibiting risky behavior based on the periodicity exceeding a periodicity threshold associated with the driver profile;
- and
- performing a corrective action based on the identification that the current driver of the vehicle is exhibiting the risky behavior.
A system for monitoring driver behavior, the system comprising:
- memory that stores one or more driver profiles, wherein each driver profile specifies a set of behavioral risk factors specific to each different driver;
- one or more sensors that capture sensor data in a vehicle when an automated driving assistant is operating, wherein at least part of the sensor data concerns one or more inputs to one or more vehicle controls of the vehicle by a current driver in the vehicle that adjust positioning of the vehicle in a roadway lane to correct one or more variations of the vehicle from a center of the roadway lane;
- and
- a processor that executes instructions stored in memory, wherein execution of the instructions by the processor:
- retrieves a driver profile specific to the current driver;
- identifies that a periodicity of the one or more variations from the center of the roadway lane corresponds to the one or more inputs to the one or more vehicle controls that adjust the positioning of the vehicle in the roadway lane;
- analyzes the sensor data to identify that the current driver of the vehicle is exhibiting risky behavior based on the periodicity exceeding a periodicity threshold associated with the driver profile;
- and
- performs a corrective action based on the identification that the current driver of the vehicle is exhibiting the risky behavior.
