1. A vehicle traveling control system of a host vehicle comprising:
- a following controller executing a following control for controlling an inter-vehicle distance between the host vehicle and a following object ahead of the host vehicle; and
a lane-keeping controller coupled with the following controller, the lane-keeping controller executing a steering control for steering the host vehicle so as to locate the host vehicle within a lane traveled by the host vehicle;
wherein a control condition of one of the following control and the steering control is changed according to the control condition of the other of the following control and the steering control; and
wherein the following controller outputs a speed alarm when a deceleration control of the following control is unable to maintain a target inter-vehicle distance between the host vehicle and a preceding vehicle ahead of the host vehicle, and the lane-keeping controller outputs a lane-keeping alarm when there is a tendency to increase a rate of change of a displacement of the host vehicle relative to the lane.
