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.

A vehicle display system recognizes, from within a color image of a forward scenery of a subject vehicle, an object such as left and right brake lights of a leading vehicle or a halt sign, each of which includes a red light element. Of the recognized object, a given position on a display area in a windshield of the subject vehicle is extracted. The extracted given position is then highlighted on the display area so that a user of the subject vehicle can properly recognize the object including the red light element.

A driver fatigue assessment device may include; a look information generator to generate look information regarding at least one of a driver's direction of a look and a locus at which a driver is looking; a visual stimulator to provide a visual stimulus within a driver's field of view at a first position and then move the location thereof to a second position; a change determination unit to determine whether the look information has changed in response to the movement of the visual stimulus; and a fatigue decision unit to assess driver fatigue based upon an output of the change determination unit.

A vehicle behavior control device for controlling acceleration/deceleration includes: a velocity acquisition device; a current position acquisition device; a preceding vehicle determination device; a following distance detection device; a preceding vehicle information acquisition device; a relative velocity calculation device of a preceding vehicle; a first evaluation index calculation device of a first evaluation index indicating an approaching/separating state to the preceding vehicle in view of the preceding vehicle velocity; a first deceleration target determination device for determining whether the first evaluation index exceeds a first deceleration threshold; and a following deceleration calculation device for calculating a first required deceleration when the first evaluation index exceeds the first deceleration threshold. The first required deceleration provides to match an actual relative velocity with a first target relative velocity, which is determined based on the first evaluation index and the following distance.

An inter-vehicle distance control apparatus is provided to provide comfortable acceleration feeling to a driver of a vehicle in various situations. The inter-vehicle distance control apparatus is configured to perform an acceleration control operation when a correction distance condition evaluation index at a present time, which takes into account a velocity of a forward object, is smaller than a threshold given by a judgment equation. The inter-vehicle distance control apparatus is configured to perform the acceleration control operation to accelerate the vehicle at a target acceleration, which is calculated from an actual relative velocity and a target relative velocity corresponding to the threshold given by the judgment equation.

A vehicle control system controls the speed of a vehicle according to actual road conditions and state of the vehicle. The control system acquires a present value of lateral acceleration occurring in a direction lateral to a controlled vehicle when the controlled vehicle avoids a collision with an obstacle or passes the obstacle. A target relative speed between the obstacle and the controlled vehicle is calculated from the present value of lateral acceleration and a turning radius of the controlled vehicle required for the controlled vehicle to avoid a collision with the obstacle or to pass the obstacle. Then, deceleration control is executed based on target relative deceleration rate at which the controlled vehicle is to be decelerated to reach the target relative speed.
摘要:
In a vehicle drive control system, a control unit calculates an evaluation index indicating an approach/separation condition of a subject vehicle during a travel and stores this evaluation index together with an inter-vehicle distance with respect to each driver in a memory device. The control unit further calculates a maximum value of the stored evaluation index for each distance, and calculates a relational equation between the distance and the calculated maximum evaluation index. The control unit determines, by correcting the relational equation, a speed control start determination equation, which determines the start timing of the automatic acceleration and/or deceleration control.
摘要:
In a vehicle speed control system, a preset offset distance is taken as a zero value of an inter-vehicle distance in a brake discriminant. When the current value of a corrected distance condition evaluation index is higher than the brake discriminant, a value on the brake discriminant is set as a target value of the corrected distance condition evaluation index. Deceleration control is started to decelerate the subject vehicle so that the deceleration of the subject vehicle becomes equal to the target deceleration of the subject vehicle computed based on the target relative speed corresponding to the set target value and the actual relative speed.
摘要:
In a driving support system, a necessary information amount determining section determines the amount of visual information necessary for safe driving. An information acquisition capacity setting section sets an information acquisition capacity of a driver. A comparing section compares the necessary information amount with the information acquisition capacity and determines a difference between the two. If a possibility of collision between an object and a vehicle is determined by a collision possibility determining section, a driving support level setting section sets a level of driving support based on the difference.
