Apparatus and method for determining driver distraction based on jerk and vehicle system

A method for determining driver distraction based on a jerk, the method comprising:

• calculating, a jerk calculating processor, a lateral jerk of a vehicle based on driving information collected when the vehicle is traveling;
• detecting, by an exception event detecting processor, an exception event defining a situation where the lateral jerk occurs during normal driving, based on the collected driving information;
• and
• detecting, by a determining processor, oversteering of the vehicle by comparing the calculated lateral jerk with a reference value and determining a driver distraction based on the detected oversteering and the exception event,
• wherein the driving information comprises a lateral acceleration, and
• wherein calculating the lateral jerk includes:
• calculating a difference value between a first low frequency signal of the lateral acceleration at a first predetermined time and a second low frequency signal of the lateral acceleration at a second predetermined time, and
• dividing the difference value by a sampling time.

A vehicle system, comprising:

• a sensor configured to detect driving information when a vehicle is traveling;
• and
• a driver distraction determination apparatus configured to:
• calculate a lateral jerk of the vehicle based on the driving information detected by the sensor,
• detect an exception event defining a situation where the lateral jerk occurs during normal driving, based on the driving information,
• detect oversteering of the vehicle by comparing the calculated lateral jerk with a reference value, and
• determine a driver distraction based on the detected oversteering and exception event,
• wherein the driving information comprises a lateral acceleration, and
• wherein the driver distraction determination apparatus is configured to:
• calculate a difference value between a first low frequency signal of the lateral acceleration at a first predetermined time and a second low frequency signal of the lateral acceleration at a second predetermined time,
• divide the difference value by a sampling time, and
• calculate the lateral jerk therefrom.
