Abstract: A vehicular engine control device provided with a control unit for performing control that automatically stops an engine installed in a vehicle when a preset stop condition is fulfilled, and a traveling information acquiring unit for acquiring travel information including vehicle speed information relating to the speed of the vehicle and steering information relating to a steering wheel. For the stop condition the vehicle speed information and steering information acquired by the traveling information acquiring unit are set including respective thresholds. The control unit switches the stop condition in accordance with changes in the vehicle speed information, the stop condition being sectioned into a plurality of regions using steering thresholds for the steering information relating to the steering handle. Automatic stop control of the engine conforming to the intentions of the driver can be implemented by the vehicular engine control device.

Abstract: When a host vehicle makes a lane change from a first lane into a second lane, an approach suppression control unit of a travel assist device monitors whether or not another vehicle, which is traveling in a third lane existing on an opposite side from the first lane with the second lane interposed therebetween, is making a lane change into the second lane. In the case it is determined that the other vehicle is making a lane change from the third lane into the second lane, the approach suppression control unit implements an approach suppression control for suppressing the host vehicle and the other vehicle from approaching each other.

Abstract: A drive assistance device 10 includes a road information acquisition unit 12, an information display unit 5, a drive assistance unit 15, and a display control unit 14 configured to report road information in front of a vehicle 1 acquired by the road information acquisition unit 12, by displaying a road image portion R indicating a shape of a road and left and right outer edges EL, ER of the road image portion R in different colors on the information display unit 5, and to display a vehicle state display part C indicating an execution state of drive assistance by the drive assistance unit 15.

Abstract: A vehicle drive control device includes a drive lane detector, a drive assist unit, and a curve road steering assist unit. The drive lane detector detects a drive lane of a subject vehicle. The drive assist unit performs drive assist control to assist the subject vehicle in lane keep driving in the drive lane. The curve road steering assist unit performs steering assist for assisting the subject vehicle in turning along a curve of a curve road if the drive lane is the curve road and if the drive assist control performed by the drive assist unit is discontinued during driving on the curve road.

Abstract: If road information indicates that a first curve zone at a near side and a second curve zone at a far side that curve in different directions are continuously located in a road, a steering assist unit of a steering assist device or a steering assist circuit finishes decreasing process of decreasing the steering assist amount when the subject vehicle passes through the first curve zone earlier than a case when the subject vehicle passes through the second curve zone.

Abstract: A steering control unit performs lane keeping control to cause a steering system to operate to reduce a distance between a width-direction center position of a lane and a position where the vehicle is traveling in the lane on the basis of a recognized state of the lane obtained by a lane recognizing unit. A road condition determining unit determines whether the road on which the vehicle is traveling is a straight road. A lane keeping responsivity setting unit sets, when it is determined by the road condition determining unit that the road on which the vehicle is traveling is a straight road, responsivity of the lane keeping control to the distance to be lower than responsivity set when it is determined that the road on which the vehicle is traveling is not a straight road.

Abstract: In a vehicle travel support system or a vehicle travel support method, a control apparatus estimates a travel path of a vehicle on the basis of the present position of the vehicle and map information, acquires from a map information storage apparatus a curve radius that is of a curve included in the travel path and that is contained in the map information, performs a vehicle turning support or a deceleration support prior to entry to the curve on the basis of a start point of the curve which is detected on the basis of front images, and performs the vehicle turning support for the curve by using the curve radius contained in the map information.

Abstract: A steering apparatus and a steering assist method are capable of being preferably used for a first curve and a second carve which are different in cornering direction and which are sequentially provided. When a vehicle travels through the first curve and the second curve, a controller in the steering apparatus shifts a steering angle control value with respect to a steering angle detection value in response to returning of a steering wheel and decrease of steering assist torque to a torque threshold value while the vehicle is running in the first curve and starts generation of the steering assist torque for the second curve before the steering angle detection value returns to a sensor median due to returning of the steering wheel.

Abstract: Control method for an electric power steering apparatus feeds back a motor current, flowing through a motor whose operation is controlled in accordance with a target motor current, so that the driving of the motor is controlled with the fed-back motor current. Peak value of the motor current is detected, and, for feedback control based on the detected peak value, the detected peak value is corrected to decrease. The thus-corrected peak value is fed back to control the motor current to conform to a target motor current value.
