Vehicle drive assist system
First Claim
1. A drive assist system for a driver'"'"'s own vehicle at least having a solid object detecting unit for detecting frontal solid objects including a first preceding vehicle traveling ahead of said own vehicle and a second preceding vehicle traveling ahead of said first preceding vehicle and a traveling control unit including a constant speed traveling control unit for controlling a vehicle speed of said own vehicle so as to travel at a constant speed and a follow-up traveling control unit for establishing said preceding vehicle as a follow-up object and for controlling traveling of said own vehicle so as to follow said preceding vehicle, comprising;
- means for inhibiting an acceleration of said own vehicle following said first preceding vehicle according to said follow-up traveling control unit when a first state is detected where said first preceding vehicle undertakes to pass said second preceding vehicle;
means for continuing to establish said first preceding vehicle as said follow-up object until a second state is detected where said first preceding vehicle travels in parallel with said second preceding vehicle;
means for changing said follow-up object from said first preceding vehicle to said second preceding vehicle when said second state changes to a third state where the speed of said first preceding vehicle is larger than that of said second preceding vehicle, and means for continuing to establish said first preceding vehicle as said follow-up object when said second state changes to a fourth state where the speed of said first preceding vehicle is smaller than that of said second preceding vehicle.

Abstract
When an own vehicle makes a follow-up traveling control targeting a preceding vehicle traveling ahead of the own vehicle, in case where the widthwise movement of the preceding is detected and a second preceding vehicle traveling ahead of the preceding vehicle is detected, the preceding vehicle is regarded as undertaking to pass the second preceding vehicle and acceleration of the own vehicle is inhibited. Further, in a situation where the preceding vehicle and the second preceding vehicle run in parallel, these vehicles can be recognized discriminatingly from each other based on the memorized widths of theses vehicle and the direction of the widthwise movement of the preceding vehicle. Further, when it is judged that the preceding vehicle travels faster than the second preceding vehicle, the target of the follow-up traveling control is changed to the second preceding vehicle.

8. A drive assist system for a driver'"'"'s own vehicle comprising:
-
a solid object detecting unit for detecting frontal said objects including a first preceding vehicle ahead of said own vehicle and a second preceding vehicle ahead of said first preceding vehicle; a traveling control unit for establishing a follow-up object and for controlling said own vehicle so as to follow said follow-up object; and an inhibiting unit for inhibiting an acceleration of said own vehicle; wherein said inhibiting unit inhibits acceleration of said own vehicle when said traveling control unit establishes said first preceding vehicle as said follow-up object and controls said own vehicle so as to follow said first preceding vehicle and when a first state is detected where said first preceding vehicle undertakes to pass said second preceding vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
