1. A vehicle driving assisting apparatus comprising:
- driving condition detecting means for detecting a driving operation of at least either an accelerator condition or a brake condition of a vehicle;
stopping point detecting means for detecting a stopping point in front of the vehicle and for calculating a distance up to the stopping point;
distance determining means for determining whether a distance up to the stopping point is shorter than a predetermined distance; and
driving operation determining means which, when the distance up to the stopping point is determined to be shorter than the predetermined distance, determines whether a vehicle driver is executing a driving operation for stopping the vehicle short of the stopping point based on a detected result of the driving condition detecting means thereby to determine a driver'"'"'s degree of recognition of traffic environment in front of the vehicle.

Abstract
A vehicle driving assisting apparatus determines whether a driver is executing a driving operation for stopping a vehicle when a distance up to a halting vehicle exiting in front of the vehicle is shorter than a distance obtained by adding a margin to an estimated braking distance for stopping the vehicle by starting a normal deceleration operation from the present vehicle speed. When the driving operation for stopping the vehicle has not been executed, an alarm is generated for causing the driver'"'"'s attention in the forward direction. This makes it possible to properly determine the driver'"'"'s degree of recognition of the traffic environment in front of the vehicle.

3. The vehicle driving assisting apparatus comprising:
-
deceleration detecting means for detecting a deceleration occurring on a vehicle;
stopping position detecting means for detecting a stopping point in front of the vehicle and for calculating a distance up to the detected point;
distance determining means for determining whether the distance up to the stopping point is shorter than a predetermined distance; and
