20090248270 | VEHICLE DRIVE ASSIST SYSTEM - When a preceding vehicle moves away during follow-up running control, it is determined whether or not a forward obstacle is recognized. When a forward obstacle is recognized, it is determined whether or not the forward obstacle satisfies any of obstacle specifying conditions corresponding to a plurality of preset types. A basic threshold value set corresponding to the satisfied type is corrected by three correction values so as to set first to third estimated-collision-time determining values. The estimated-collision-time determining values are compared with an estimated collision time of a subject vehicle with respect to the forward obstacle, and acceleration control on the subject vehicle is limited stepwise in accordance with the comparison values. | 10-01-2009 |

20130214718 | MOTOR CONTROL DEVICE - A motor control device includes a feedback filter that has filter characteristics that a frequency response gain is substantially one at frequencies equal to or lower than a filter cutoff frequency, a frequency response gain decreases with increase in frequency in a range from the filter cutoff frequency ωfL to a filter upper limit frequency ωfH higher than the filter cutoff frequency ωfL, and a frequency response gain is substantially constant at frequencies equal to or higher than the filter upper limit frequency ωfH, and performs computing to apply the filter characteristics to a feedback transfer function, wherein a control-constant set unit sets a speed gain Kv and at least one of the filter cutoff frequency ωfL and the filter upper limit frequency ωfH to reduce a ratio of the filter upper limit frequency ωfH to the filter cutoff frequency ωfL with increase in the speed gain Kv. | 08-22-2013 |
20130257274 | APPARATUS FOR CONTROLLING HEAD LAMP FOR VEHICLE - There is provided an apparatus for controlling a head lamp for a vehicle. A control condition determining unit determines whether a condition for controlling a head lamp is established or not based upon whether a vehicle ahead is present or not, and a distance between the vehicle ahead and the vehicle. When the control condition is determined to be established, an illumination range control unit compares a reference pattern stored and held in a reference pattern holding unit and an illumination pattern of the head lamp recognized by an illumination pattern recognition unit, and controls the illumination range of the head lamp via an actuator in order that both patterns agree with each other. | 10-03-2013 |
20130259309 | DRIVING SUPPORT APPARATUS - There is provided a driving support apparatus. A recognition controller determines whether an object detected by processing a captured image by an object detection unit is a smoke-like object or not in a smoke-like object determination unit. When the detected object is determined to be the smoke-like object, the recognition controller checks a range distribution in a region of the smoke-like object, adds the result as attribute information of “density”, and transmits the resultant to a controller. The controller decides in a support operation level decision unit whether a pre-crash brake control can be executed or not and an intensity of an operation based on the attribute information of the smoke-like object. Thus, even if the smoke-like object is detected, an appropriate driving support process according to the condition can be executed. | 10-03-2013 |
20130261916 | DRIVING SUPPORT APPARATUS FOR VEHICLE - There is provided a driving support apparatus for a vehicle. When a height of a three-dimensional object extracted as a control subject is less than a set height, and as the height of the control subject becomes lower, a driving control unit increases the range of the braking control that is sequentially inhibited in the stepwise manner from the highest braking level to the lowest braking level. | 10-03-2013 |
20130261951 | DRIVING SUPPORT APPARATUS FOR VEHICLE - There is provided a driving support apparatus for a vehicle. A driving control unit determines whether or not a three-dimensional object ahead is a three-dimensional object having high reliability as a control object for an automatic brake control based on a condition set beforehand, when possibility of collision between the vehicle and the three-dimensional object ahead is determined to be high. When the reliability of the three-dimensional object ahead as the control object is determined to be low and the amount of increase in the accelerator opening degree is equal to or larger than a set value, the driving control unit cancels the execution of the automatic brake control. | 10-03-2013 |
20140077746 | MOTOR CONTROL DEVICE - A motor control device includes an operation determination unit that determines whether a motor is in an operating state or in a stopped state based on an operation command signal or an operation signal and an amplitude estimation unit that, based on a determination result of the operation determination unit, sequentially estimates a vibration amplitude value from a control state quantity of a feedback control unit or a current control unit separately for a case where the motor is operated and a case where the motor is stopped and outputs the vibration amplitude value. A function of outputting an amplitude of a high-frequency vibration that occurs in a mechanical device including a control system as information useful for estimating an occurrence factor of the vibration is provided. | 03-20-2014 |
20140188345 | VEHICLE DRIVING ASSISTANCE DEVICE - In a vehicle driving assistance device, a steering controlling unit estimates lane lines behind a subject vehicle based on lane lines recognized ahead of the subject vehicle and a running state of the subject vehicle, determines whether or not there is a passing vehicle on an adjacent lane based on the estimated lane lines behind the subject vehicle and a solid substance that is detected behind the subject vehicle by a solid substance detecting unit. If there is a passing vehicle a set distance behind the subject vehicle, the steering controlling unit corrects a steering angle of steering control set based on the lane lines ahead of the subject vehicle toward a direction in which the subject vehicle moves wary from the passing vehicle. | 07-03-2014 |
