DRIVING ASSISTANCE DEVICE AND COMPUTER PROGRAM

Provided is a driving assistance device allowing, when a vehicle is parked in a parking lot, provision of driving assistance based on an appropriate travel path. The device is configured such that when a vehicle is parked in a parking lot, an intra-parking-lot network representing a route that can be selected by the vehicle in the parking lot is obtained. Using this network, a candidate entry path for a vehicle's travel path from an entrance to the parking lot to a parking location is generated and obtained using the intra-parking-lot network based on a first condition. If determined that the condition for suitability is not satisfied, the candidate entry path determined not to satisfy the condition for suitability is modified based on a second condition different from the first condition and driving assistance is provided based on the modified candidate entry path.
