Driving assist system for vehicle
First Claim
1. A vehicle driving assist system, comprising:
- an obstacle detection device that detects an obstacle present in each of two obstacle detection directions with respect to a subject vehicle;
a TTC calculation device that calculates a TTC between the subject vehicle and each of the obstacles, that is a time to contact that expresses a length of time until the subject vehicle and the obstacle come to mutual contact, based on detection results of the obstacle detection device;
a lateral reaction force control device that controls a reaction force generated at a first vehicle operation equipment for drive operation in a lateral direction of the subject vehicle based on a first TTC which is smaller in the TTCs calculated in the TTC calculation device; and
a longitudinal reaction force control device that controls a reaction force generated at a second vehicle operation equipment for drive operation in a longitudinal direction of the subject vehicle based on a second TTC which is larger in the TTCs calculated in the TTC calculation device.

Abstract
In a vehicle driving assist system, an obstacle detection device detects an obstacle present in each of two obstacle detection directions with respect to a subject vehicle; and a TTC calculation device calculates a TTC between the subject vehicle and each of obstacles based on detection results of the obstacle detection device. A lateral reaction force control device controls a reaction force generated at a vehicle operation equipment for drive operation in a lateral direction of the subject vehicle based on a first TTC which is smaller in the TTCs calculated in the TTC calculation device; and a longitudinal reaction force control device controls a reaction force generated at a vehicle operation equipment for drive operation in a longitudinal direction based on a second TTC which is larger in the TTCs.
