This application is a National Stage Entry of PCT/JP2019/048688 filed on Dec. 12, 2019, which claims priority from Japanese Patent Application 2018-232877 filed on Dec. 12, 2018 the contents of all of which are incorporated herein by reference, in their entirety.
The present invention relates to a driving assistance device, a driving assistance method, and a storage medium in which a program is stored.
There is a method of assisting with safe driving by acquiring acceleration information of a moving object such as a vehicle, determining that a dangerous event (an event that may lead to an accident) has occurred in a case where sudden steering or sudden braking is detected, and giving feedback on the event to a driver.
FIG. 1 is a diagram illustrating an outline of a driving assistance system according to the present embodiment.
FIG. 2 is a hardware configuration diagram of a driving assistance device according to the present embodiment.
FIG. 3 is a functional block diagram of the driving assistance device according to the present embodiment.
Hereinafter, a driving assistance device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating an outline of a driving assistance system including a driving assistance device according to the present embodiment.
As illustrated in FIG. 1, a driving assistance system 100 has a configuration in which a driving assistance device 1 and a drive recorder 2 are connected to each other via a wireless communication network or a wired communication network. The driving assistance device 1 is, for example, a computer server of a company which performs driving assistance, and is a computer server (cloud server) that is connected to a communication network. The drive recorder 2 is provided in each of a plurality of moving objects. FIG. 1 illustrates a vehicle 20 as an example of the moving object. The drive recorder 2 has a camera, and transmits captured images of the inside and the outside of the vehicle 20 to the driving assistance device 1. The drive recorder 2 is a type of driving status sensing device. The drive recorder 2 is also a type of driver sensing device.
