Abstract
A driving control system has a position/speed information detecting section for detecting the position and speed of a host vehicle, a communication unit for acquiring the position and speed information of another vehicle, a proximity position estimating section that estimates a proximity position at which the host vehicle and the other vehicle approach each other and a proximity position changing unit that, when the host vehicle and the other vehicle are travelling on the same lane at the same time, changes the proximity position to a changed proximity position outside of a waiting time generation area. A travelling plan generation section generates a travelling plan while the other one of the host-vehicle and the other vehicle enters the waiting time generation area. A communication unit transmits the travelling plan to the other vehicle, and a travel driving unit executes the driving of the host vehicle according to the travelling plan.
