Driving assistance device
Provided is a driving assistance device capable of responding to situations in which an obstacle to automatic driving (which can include remote control driving) occurs in a situation other than when parking a vehicle in a garage. This driving assistance device has a peripheral environment detection unit that detects peripheral environment information, which is information pertaining to the environment around a vehicle, and an automatic driving control unit that, on the basis of the peripheral environment information, controls automatic driving wherein the vehicle is made to travel without involving driving operations by an occupant. When it is determined that automatic driving based on the peripheral environment information is not possible, the automatic driving control unit continues, by means of remote control, the automatic driving without involving driving operations by the occupant.

the automated driving control unit is configured to:
implement the autonomously oriented type of automated driving, in a case it is determined that the autonomously oriented type of automated driving is capable of being implemented;
output a calling signal to the surrounding environment of the user's own vehicle through a wireless communications device, and determine whether columnar traveling is capable of being implemented based on information from a surrounding vehicle which has output a response signal in response to the calling signal, in a case it is determined that the autonomously oriented type of automated driving cannot be implemented;
implement the columnar traveling based on information from the surrounding vehicle, in a case it is determined that the columnar traveling can be implemented and
implement the heteronomously oriented type of automated driving by remote control using wireless communications with the external device in a case it is determined that the columnar traveling cannot be implemented, and
the automated driving control unit includes a remote operation control unit configured to transmit, to the external device, a sound outside of the user's own vehicle collected by a sound collecting sensor mounted on the user's own vehicle to the external device when the heteronomously oriented type of automated driving is implemented.
