摘要： According to conventional art, if there is an obstacle on the left of a vehicle, a control threshold value is set so as to avoid the obstacle. If the control threshold value is exceeded, the vehicle is controlled in accordance with a deviation quantity so as to return to a position where the control threshold avoids being exceeded. However, even if a risky oncoming vehicle is approaching the vehicle on the right, the vehicle is controllably moved toward the oncoming vehicle. Thus, disadvantageously, a driver has a sense of fear or discomfort. A vehicle control apparatus according to the present invention includes a calculation section configured to calculate a first risk level present on the left of the vehicle and a second risk level present on the right of the vehicle, a setting section configured to set a first control threshold for the left of the vehicle based on the first risk level and to set a second control threshold for the right of the vehicle based on the second risk level, a change section configured to change at least one of the first and second control thresholds based on the first and second risk levels, and a control section configured to control the vehicle based on the changed control threshold.

摘要： A conventional brake control can generate only a small yaw moment compared with a steering control, so that reliable avoidance of obstacles cannot be obtained. With a steering control, the driver gets behind the wheel every time when crossing a lane and has an uncomfortable feeling. To solve these problems, a traveling aid device comprises: a detection unit for detecting the traveling state of a vehicle, the position of a lane marker, and the positions and types of obstacles around the vehicle; a calculation unit for calculating, based on the traveling state of the vehicle, the position of the lane marker, and the positions and types of the surrounding obstacles, a target yaw moment so as to prevent a departure from the lane marker and a collision with the surrounding obstacles; and a distribution unit for distributing, based on at least one of the traveling state of the vehicle, the position of the lane marker, and the positions and types of the surrounding obstacles, the target moment to a first actuator for controlling the driving/braking force and a second actuator for controlling the steering.

摘要： A lane departure prevention device includes departure prevention control means that performs control to prevent deviation from a lane based on a result of detection means such as sensors and a camera, driver's intention determination means that determines driver's steering intention and actuator activation limiting means that limits activation of an actuator based on the driver's steering intention from the driver's intention determination means. The driver's intention determination means calculates a variation ΔTh in the steering torque detected and a variation ΔTs in the control command value to a steering actuator, and determines that, when |ΔTh|−|ΔTs| is a threshold or more, driver's operational intention is present and limits the activation of the departure prevention control. This can avoid the interruption of departure prevention control in response to activation of an actuator for lane departure avoidance that a driver does not intend because of erroneous detection that a driver intends as such.
