Apparatus and method for determining driving state
First Claim
1. An apparatus for determining a driving state, the apparatus comprising:
- a jerk calculator configured to determine a minimum prediction jerk generated in an interval until an ego vehicle arrives at a location of a preceding vehicle, using location, velocity, and acceleration information of the ego vehicle at a current time and location, velocity, and acceleration information of the preceding vehicle and determine a permission jerk of a driver of the ego vehicle;
a determiner configured to determine whether the minimum prediction jerk determined in the interval is greater than the permission jerk of the driver and determine a careless driving state based on a driving operation state of the driver when the minimum prediction jerk is greater than the permission jerk of the driver; and
a signal processor configured to output an alert when it is determined as the careless driving state by the determiner.

Abstract
An apparatus and a method for determining a driving state are provided. The apparatus includes a jerk calculator configured to determine a minimum prediction jerk generated in an interval until an ego vehicle arrives at a location of a preceding vehicle, using location, velocity, and acceleration information of the ego vehicle at a current time and location, velocity, and acceleration information of the preceding vehicle and determine a permission jerk of a driver of the ego vehicle, a determiner configured to determine whether the minimum prediction jerk is greater than the permission jerk of the driver and determine a careless driving state based on a driving operation state of the driver when the minimum prediction jerk is greater than the permission jerk of the driver, and a signal processor configured to output an alert when it is determined as the careless driving state.

17. A method for determining a driving state, the method comprising:
-
obtaining location, velocity, and acceleration information of an ego vehicle at a current time and location, velocity, and acceleration information of a preceding vehicle; determining a minimum prediction jerk generated in an interval until the ego vehicle arrives at a location of the preceding vehicle, using the location, velocity, and acceleration information of the ego vehicle at the current time and the location, velocity, and acceleration information of the preceding vehicle and determining a permission jerk of a driver of the ego vehicle; determining whether the minimum prediction jerk determined in the interval is greater than the permission jerk of the driver and determine a careless driving state based on a driving operation state of the driver when the minimum prediction jerk is greater than the permission jerk of the driver; and outputting an alert, when it is configured to be determined the careless driving state. - View Dependent Claims (18, 19, 20)
