摘要： When a variation amount of a driving operation falls outside of a determining reference, a determining system determines that an awakening degree of a driver is decreased. The determining system changes the determining reference by whether or not a preceding vehicle is existing within a given distance. Therefore, in consideration of peripheral traffic environments such as existence and absence of the preceding vehicle, the awakening degree of the driver is determined, so that determining accuracy of the awakening degree is enhanced more than that of a conventional method.

摘要： A driving assistance apparatus assists turning operation of a vehicle at an intersection by taking critical variables into account. The apparatus first estimates friction coefficient of a road to determine a suitable acceleration in turning, and then calculates a required period of time to finish turning by using other variables such as a width of the road derived by one of the functions of the apparatus. Based on the comparison with the time that the oncoming vehicle in the opposite lane will take to arrive at the intersection and the required time for turning, driving assistance for the vehicle to turn safely at the intersection can be appropriately provided.

摘要： 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.

摘要： A collision possibility determining unit determines that a subject vehicle has possibility of colliding with a certain vehicle when both the following two determinations are fulfilled. The first determination is that the traveling state of the subject vehicle is proper. The second determination is that a relative position between the subject vehicle and the certain vehicle continues to be maintained at the same relationship for a given period. When the collision possibility is determined to be existing, an alarm generating unit generates an alarm that arouses driver's attention. Thus, collision possibility is determined based on the relative position relationship with another vehicle, so that an alarm relating to another vehicle as an obstacle can be generated at a proper timing.

摘要： A collision determination apparatus detects a current value of a lateral acceleration of a subject vehicle for calculating a collision risk index, and the collision risk index is used to determine the risk of collision of the subject vehicle with a front object. As the collision risk index takes the lateral acceleration of the subject vehicle into account, the collision risk index correctly represents a risk of collision of the subject vehicle with the front object when the subject vehicle is traveling in a condition that is under an influence of the lateral acceleration.
