Abstract
A speed maintenance instruction is output when a vehicle enters a next intersection and a predetermined condition is satisfied. It is determined whether a forward obstacle is disposed between the vehicle and the next intersection. A possibility of collision with the forward obstacle is determined if the forward obstacle is disposed between the vehicle and the next intersection and the vehicle maintains a current vehicle speed. When the possibility of collision is determined, the speed maintenance instruction is not output even if the predetermined condition is satisfied.
Claims9
A driving assistance device comprising:
- an instruction control unit that outputs a speed maintenance instruction by displaying a speed maintenance instruction icon for prompting a driver to execute a speed maintenance operation when a vehicle enters a next intersection and a predetermined condition is satisfied;
- a forward obstacle determination unit that determines whether a forward obstacle is disposed between a vehicle position of the vehicle and the next intersection by at least one of vehicle-to-vehicle communication and road-to-vehicle communication;
- and
- a collision possibility determination unit that determines whether there is a possibility of collision with the forward obstacle if the forward obstacle is disposed between the vehicle position and the next intersection and the vehicle maintains a current vehicle speed, wherein:
- when the collision possibility determination unit determines that there is the possibility of collision with the forward obstacle if the vehicle maintains the current vehicle speed, the instruction control unit does not output the speed maintenance instruction even if the predetermined condition is satisfied.
A non-transitory tangible computer readable storage medium comprising instructions being executed by a computer, the instructions including a computer-implemented method for a control unit of a driving assistance device, which outputs a speed maintenance instruction by displaying a speed maintenance instruction icon for prompting a driver to execute a speed maintenance operation when a vehicle enters a next intersection and a predetermined condition is satisfied, the instructions including:
- determining whether a forward obstacle is disposed between a vehicle position of the vehicle and the next intersection by at least one of vehicle-to-vehicle communication and road-to-vehicle communication;
- determining whether there is a possibility of collision with the forward obstacle if determining that the forward obstacle is disposed between the vehicle position and the next intersection and the vehicle maintains a current vehicle speed;
- and
- not outputting the speed maintenance instruction even when the predetermined condition is satisfied if determining that there is the possibility of collision with the forward obstacle and the vehicle maintains the current vehicle speed.
