Driving support apparatus, control method of vehicle, and non-transitory computer-readable storage medium

Abstract

A driving support apparatus in a vehicle, includes: an information acquisition unit configured to acquire peripheral information of the vehicle; a risk prediction unit configured to predict a risk region on the periphery of the vehicle using the peripheral information; a sight line specifying unit configured to specify a position of a sight line of a driver of the vehicle in the peripheral information; and a control unit configured to switch driving support control based on a degree of deviation between the risk region predicted by the risk prediction unit and the position of the sight line specified by the sight line specifying unit.

What is claimed is: 
     
         1 . A driving support apparatus in a vehicle, comprising:
 an information acquisition unit configured to acquire peripheral information of the vehicle;   a risk prediction unit configured to predict a risk region on the periphery of the vehicle using the peripheral information;   a sight line specifying unit configured to specify a position of a sight line of a driver of the vehicle in the peripheral information; and   a control unit configured to switch driving support control based on a degree of deviation between the risk region predicted by the risk prediction unit and the position of the sight line specified by the sight line specifying unit.   
     
     
         2 . The apparatus according to  claim 1 , further comprising an estimation unit configured to estimate the position of the sight line in the peripheral information using a learned model learned using data of the position of the sight line of the driver having a specific attribute at the time of driving,
 wherein the control unit further switches the driving support control based on the degree of deviation between the position of the sight line estimated by the estimation unit and the position of the sight line specified by the sight line specifying unit.   
     
     
         3 . The apparatus according to  claim 1 , wherein the control unit switches contents of a notification to the driver based on the degree of deviation. 
     
     
         4 . The apparatus according to  claim 3 , wherein switching of the contents of the notification includes change of one of a volume, a notification timing, an utterance speed, and a tone. 
     
     
         5 . The apparatus according to  claim 3 , wherein switching of the contents of the notification includes change of words for directly notifying contents of a risk and words for indirectly notifying the contents of the risk. 
     
     
         6 . The apparatus according to  claim 3 , wherein the contents of the notification include words used to guide the sight line of the driver to the risk region. 
     
     
         7 . The apparatus according to  claim 1 , wherein the control unit switches a threshold for a control parameter of the driving support control based on the degree of deviation. 
     
     
         8 . The apparatus according to  claim 1 , further comprising a decision unit configured to decide a threshold for the degree of deviation in accordance with information of the driver,
 wherein the control unit switches the driving support control using the threshold decided by the decision unit.   
     
     
         9 . The apparatus according to  claim 8 , wherein the information of the driver includes one of an operation mode of the vehicle set by the driver, a driving history of the driver, and attribute information of the driver. 
     
     
         10 . The apparatus according to  claim 1 , further comprising a unit configured to predict, using the peripheral information of the vehicle, a collision possibility between the vehicle and a target represented by the peripheral information,
 wherein the control unit switches the driving support control in accordance with the predicted collision possibility.   
     
     
         11 . The apparatus according to  claim 10 , wherein if the predicted collision possibility exceeds a predetermined threshold, the control unit operates a collision safety device before collision. 
     
     
         12 . A control method of a vehicle, comprising:
 acquiring peripheral information of the vehicle;   predicting a risk region on the periphery of the vehicle using the peripheral information;   specifying a position of a sight line of a driver of the vehicle in the peripheral information; and   switching driving support control based on a degree of deviation between the risk region predicted in the predicting and the position of the sight line specified in the specifying.   
     
     
         13 . A non-transitory computer-readable storage medium storing a program configured to cause a computer mounted in a vehicle to function as:
 an information acquisition unit configured to acquire peripheral information of the vehicle;   a risk prediction unit configured to predict a risk region on the periphery of the vehicle using the peripheral information;   a sight line specifying unit configured to specify a position of a sight line of a driver of the vehicle in the peripheral information; and   a control unit configured to switch driving support control based on a degree of deviation between the risk region predicted by the risk prediction unit and the position of the sight line specified by the sight line specifying unit.
