Claim 0:
1. A driving assistance control device of a vehicle, the driving assistance control device comprising an electronic control device configured to:
acquire a setting vehicle speed set by a driver;
detect a preceding vehicle on a route of the vehicle;
determine whether a road on which the vehicle travels is an uphill road;
detect a peak of the uphill road when it is determined that the road on which the vehicle travels is the uphill road;
when the preceding vehicle is not detected, control a speed of the vehicle such that the speed matches the setting vehicle speed, and when the preceding vehicle is detected, control the speed of the vehicle such that the vehicle follows the preceding vehicle by maintaining a specified inter-vehicle distance; and
when it is determined that the road on which the vehicle travels is the uphill road and when controlling the speed of the vehicle such that the vehicle follows the preceding vehicle;
in a case where the preceding vehicle is no longer detected, decelerate the vehicle to a reduced speed until it is determined that the road on which the vehicle travels is no longer the uphill road, or until a certain period of time elapses, wherein a magnitude of deceleration of the vehicle is changed according to an incline of the uphill road;
in a case where the preceding vehicle changes lanes and is no longer detected on the route of the vehicle and the peak of the uphill road is detected to be within a predetermined distance of the vehicle, inhibit the acceleration of the vehicle or decelerate the vehicle; and
in a case where the preceding vehicle changes lanes and is no longer detected on the route of the vehicle and the peak of the uphill road is not detected to be within the predetermined distance of the vehicle, permit the acceleration of the vehicle.
