    摘要: 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.

    摘要: 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.

    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 vehicle speed control method calculates a present value KdB_c(a)_p of a corrected evaluation index of approach/separation condition by the following equation, and starts deceleration control when the determined present value KdB_c(a)_p exceeds a threshold value determined by a braking determining equation. In the deceleration control, a corrected target relative speed is determined based on an evaluation index KdB: KdB_c  ( a ) = 10 × log 10  (  - 2 × VrGy - a × VrGy_offset Ds 3 × 1 5 × 10 - 8  ) wherein VrGy_offset, VrGy, a, Ds indicate a curve-time target speed, a difference between the curve-time target speed and a speed of a subject vehicle, a constant and a curve entrance arrival distance, respectively.
