摘要： A collision probability index value corresponding to a probability of collision between a host vehicle and an obstacle is calculated based on the information indicating the relative relationship between the host vehicle and the obstacle; and the alarming braking operation is performed to cause a driver to recognize that a collision may occur by changing at least one of the drive power and the braking force when the collision probability index value reaches a predetermined threshold value. In the alarming braking operation, a target acceleration that is used as a target value in the alarming braking operation is set based on the acceleration of the host vehicle, which is detected when the collision probability index value reaches the predetermined threshold value; and at least one of the drive power and the braking force is controlled so that the target acceleration is achieved.

摘要： In a travel supporting control system 10 including an LDW/LKA system 17 which performs traveling-lane keeping assist control so that a vehicle V travels without deviating from the lane along which it travels, the LDW/LKA system 17 calculates a virtual lane width W, which is the width of the lane narrowed by an obstacle O detected by an obstacle detecting sensor 11, and stops the traveling-lane keeping assist control when the calculated virtual lane width W is so narrow as to be equal to or smaller than a threshold value and an avoidance operation of the driver is required. Accordingly, since the operation of LDW or LKA can be stopped at a proper timing, it becomes possible to prevent interference between the operation of the driver and the operation of the system for keeping the lane.

摘要： An object of the present invention is to reliably carry out warning braking in a situation where the warning braking is needed and a crew can recognize the warning braking, and prevent the crew from feeling an unnatural sensation due to the warning braking in a situation where the warning braking is needed but the crew cannot effectively recognize the warning braking. If an obstacle is present ahead of the vehicle, the driver does not carry out brake operation, the driver is looking aside, and the vehicle may collide with the obstacle, the maximum target deceleration Gbt2max for the warning braking is computed. If automatic travel control is not carried out or if automatic travel control is being carried out and its target deceleration Gbt4 is less than a reference value Gbt4s smaller than the maximum target deceleration Gbt2max, the warning braking is carried out. However, when the target deceleration Gbt4 for the automatic travel control is larger than the allowable reference value Gbt4s for warning braking, the warning braking is not carried out.

摘要： A driving support device performs collision avoidance support on a vehicle relative to a leading vehicle present in a travelling direction based on a time-to-collision Ta as a time that the vehicle takes to collide with the leading vehicle. A lateral change amount calculation portion detects relative lateral velocity Vy, which is a relative time-dependent change amount between the vehicle and the leading vehicle. A storage portion stores steering time T1, which is a time required for the vehicle to avoid the leading vehicle by steering. The storage portion stores activation threshold TH1, which is a threshold to determine activation of the driving support based on the relative lateral velocity Vy. When a relative lateral velocity Vy at a time when the time-to-collision Ta is the steering time T1 or more is the activation threshold TH1 or more, a support management portion restrains the activation of the driving support.

摘要： In a braking force control apparatus which controls a braking force applied to a vehicle based on a relation thereof with an obstacle ahead of the vehicle, irrespective of a braking operation of a driver, a lateral force is predicted which can be generated in cases where avoidance steering is carried out by the driver, in order to avoid an obstacle which has been detected, and an actual braking force actually applied to a longitudinal direction of the vehicle is limited in accordance with a braking force which can be applied in the longitudinal direction of the vehicle and which is calculated based on the lateral force thus predicted. According to this, in the braking force control apparatus which controls the braking force of the vehicle, the lateral force for avoiding a collision with the obstacle by means of steering is obtained.

摘要： A peripheral object detection apparatus that is installed in a vehicle to detect a peripheral object obstructing travel by a vehicle includes: a radar that obtains a reflection intensity by transmitting an electromagnetic wave and receiving an electromagnetic wave reflected by an object; and a determination unit that calculates an integrated value of an amount of variation in the reflection intensity within a predetermined section, obtained by the radar, and determines on the basis of the integrated value whether or not the object is a low object not obstructing travel by the vehicle.
