A vehicle traveling control apparatus includes an obtaining unit, a detector, and a controller. The obtaining unit obtains traveling environment information. The traveling environment information includes at least lane line information of a lane along which an own vehicle travels and preceding vehicle information. The detector detects traveling information of the own vehicle. The controller performs a steering control on a basis of the traveling environment information and the traveling information. When the obtaining unit obtains only the lane line information and when the obtaining unit obtains both the lane line information and the preceding vehicle information, the controller performs the steering control on a basis of the lane line information.

A vehicle steering control apparatus includes a target course setter, a first control quantity calculator, a second control quantity calculator, a control rate variator, and a steering controller. The target course setter sets, based on forward environment information, a target course to be traveled by an own vehicle. The first control quantity calculator calculates a first control quantity that allows the own vehicle to travel along the target course. The second control quantity calculator calculates a second control quantity based on a steering angle. The control rate variator variably sets, in accordance with a vehicle speed, a first rate of the first control quantity and a second rate of the second control quantity. The steering controller calculates a steering control quantity, based on the first control quantity corrected based on the first rate and the second control quantity corrected based on the second rate, and executes a steering control.

A vehicle traveling control apparatus includes a first information obtaining unit, a second information obtaining unit, a traveling controller, a detector, and a calculator. The first information obtaining unit obtains information on a traveling environment of an own vehicle as traveling environment information. The second information obtaining unit obtains information on traveling of the own vehicle as traveling information. The traveling controller performs an evacuation traveling control, based on the traveling environment information and the traveling information. The evacuation traveling control causes an evacuation traveling of the own vehicle to be executed. The detector detects an abnormal state of a driver of the own vehicle. The calculator calculates waiting time during which waiting is performed from the detection of the abnormal state of the driver to starting of the evacuation traveling control, when the abnormal state of the driver is detected by the detector.

A travel control apparatus for a vehicle detects a vehicle to be passed that is a target of passing and is in front of the vehicle equipped with the apparatus in the traveling lane thereof, detects a parallel traveling vehicle that is traveling in a lane that is adjacent to a lane to which the vehicle performs lane changing to pass the vehicle to be passed and is located on the opposite side of the lane which the vehicle to be passed is traveling, monitors the vehicle to be passed and the parallel traveling vehicle, and variably controls a passing maneuver with respect to the vehicle to be passed on the basis of a monitoring result.

Travel control apparatus for vehicle

A travel control apparatus for a vehicle detects a vehicle to be passed that is an target of passing and is located in front of a vehicle equipped with the travel control apparatus in a traveling lane thereof on the basis of peripheral environment information and travel information, detects a following vehicle that is behind the vehicle in the traveling lane thereof as a following vehicle in the original lane on the basis of the peripheral environment information, monitors the vehicle to be passed and the following vehicle in the original lane, and variably controls a passing maneuver with respect to the vehicle to be passed on the basis of a monitoring result.

A travel control apparatus for a vehicle includes: a travel environment information acquisition unit that acquires travel environment information on a travel environment where the vehicle travels; a travel information detector that detects travel information on the vehicle; and an overtaking controller that detects an overtaking target vehicle ahead of the vehicle in an identical travel lane on the basis of the travel environment information and the travel information, and overtakes the overtaking target vehicle using automatic driving control. When failures are detected in relation to the travel environment information acquisition and in a steering system of the vehicle during the overtaking control, the overtaking controller modifies the overtaking control by activating required substitute control in accordance with the travel environment information obtained most recently before detecting the travel environment information acquisition failure, information on the overtaking target vehicle, the travel information, and conditions during the overtaking control.

In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information, and a travel information detector detects travel information relating to the vehicle. The apparatus executes automatic driving control based on such information pieces. A vehicle peripheral object detector detects an object around the vehicle, separately to the travel environment information acquisition unit. An environment information acquisition failure detector detects an acquisition failure in the travel environment information acquisition unit. Upon an acquisition failure of the travel environment information, an evacuation controller executes evacuation control by evacuating the vehicle to the roadside through automatic driving based on the travel environment information detected most recently before the acquisition failure and the travel information, and activates the vehicle peripheral object detector and, when an object is detected on the periphery around the vehicle, executes the evacuation control.

In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.

When a vehicle equipped with a driving support apparatus moves from an original traveling lane into a lane for passing in order to pass a preceding vehicle and an oncoming vehicle appears in the lane for passing, the safe passing of the preceding vehicle is determined to be impossible and the passing is interrupted even when the oncoming vehicle decelerates, in the case where a deceleration change amount of the oncoming vehicle is smaller than a threshold. On the other hand, when the deceleration change amount of the oncoming vehicle is equal to or greater than the threshold, whereby safety with respect to surrounding vehicles can be confirmed, and it is determined the vehicle can be safely returned in front of the preceding vehicle, the passing of the preceding vehicle is performed.

Driving support apparatus for vehicle

When an oncoming vehicle in an oncoming lane is detected in the case where a vehicle equipped with a driving support apparatus moves to a position across a portion of a boundary between an original traveling lane of the vehicle and the oncoming lane in order to pass a preceding vehicle, passing control is interrupted. When the departure of the oncoming vehicle from the oncoming lane is confirmed, the interruption of the passing control is canceled and the passing is performed. When the oncoming vehicle does not depart, or when it the oncoming vehicle is determined to depart but a vehicle following the oncoming vehicle is detected, the interruption of the passing control is maintained and the vehicle is returned to behind the preceding vehicle in the original traveling lane.

During a self-driving control, when an acquisition failure occurs in traveling environment information acquisition required for performing self-driving, and a failure of a steering system of a vehicle equipped with the vehicle driving control apparatus is detected, a brake controller sets an evacuation course along which the vehicle is to travel safely within traveling environment, based on traveling environment information detected last time before the acquisition failure of the traveling environment information, and executes a deceleration of the vehicle and a yaw brake control that applies a yaw moment to the vehicle based on the evacuation course.
