  • Publication number: 20150321555
    Abstract: A total certainty factor indicating a total degree of certainty of the parking frame certainty degree and the parking frame entering certainty degree is calculated based on a parking frame certainty degree indicating the degree of certainty that a parking frame is present in a travel direction of a vehicle, and a parking frame entering certainty degree indicating the degree of certainty that the vehicle enters the parking frame. When the total certainty factor is low, acceleration of the vehicle controlled according to an operation amount of an accelerator pedal for instructing a driving force by operation of a driver is suppressed with a low suppression degree, as compared with a case where the total certainty factor is high. Further, the acceleration of the vehicle is suppressed at a low suppression degree according to the travel direction of the vehicle.

  • Publication number: 20150323785
    Abstract: A three-dimensional object detection has an image capturing device, an image conversion unit, a three-dimensional object detection unit, a three-dimensional object assessment unit, first and second foreign matter detection units and a controller. The image capturing device captures images rearward of a vehicle. The three-dimensional object detection unit detects three-dimensional objects based on image information. The three-dimensional object assessment unit assesses whether or not a detected three-dimensional object is another vehicle. The foreign matter detection units detect whether or not foreign matter has adhered to a lens based on the change over time in luminance values for each predetermined pixel of the image capturing element and the change over time in the difference between an evaluation value and a reference value. The controller outputs control commands to the other means to suppress the assessment of foreign matter as another vehicle when foreign matter has been detected.

  • Publication number: 20150321667
    Abstract: A vehicle acceleration suppression device and a vehicle acceleration suppression method are provided to be capable of suppressing a degradation in a drive performance and suppressing acceleration at the time of an incorrect manipulation of an accelerator, at the time of parking. Based on a parking frame certainty degree indicative of a degree of certainty that there is a parking frame in a vehicle travel direction and a parking frame entering certainty degree indicative of a degree of certainty that the vehicle enters the parking frame, a total certainty degree indicative of a total degree of certainty of the parking frame certainty degree and the parking frame entering certainty degree is set. As the total certainty degree is higher, a suppression degree of the vehicle acceleration to be controlled in response to a manipulation amount of an accelerator pedal manipulated by a driver to instruct a drive force is increased.

  • Publication number: 20150325005
    Abstract: A water droplet detection device has an image capturing unit and a water droplet detection unit. The image capturing unit has a photographic optical system that an area captures an image of a predetermined area. The water droplet detection unit sets an arbitrary attention point in the captured image, a plurality of first reference points inside an imaginary circle of a predetermined radius having the attention point as a center the imaginary circle, and a plurality of second reference points corresponding to the first reference points outside the imaginary circle. The water droplet detection unit detects edge information between the first reference points and second reference points, and assesses a circularity strength of the edge information to detect a water droplet attached to the photographic optical system. The water droplet detection device can be used with an image conversion unit to form a three-dimensional object detection device.

  • Publication number: 20150317526
    Abstract: A parking frame drawn on a road surface is reliably detected. An imager (10) installed on a vehicle (1) captures an image (I) including at least a road surface around the vehicle (1). A candidate white-line area detector (30) detects, from the captured image (I), a candidate white-line area which is possibly a part of a parking frame. A parking-frame-similitude calculator (40) calculates the brightness distribution of the detected candidate white-line area and the surroundings of boundary points of a road surface. When the brightness distribution satisfies a certain condition, the parking-frame similitude or the degree to which the candidate white-line area forms a parking frame, is determined to be low. When a parking-frame similitude of the candidate white-line area forming a parking frame is detected in the image (I) by a parking-frame detector (60), the credibility (U) for the detected parking frame is set low.

  • Publication number: 20150296108
    Abstract: A vehicle-mounted camera device that is mounted on a vehicle and captures a surrounding image from which lights are collected by a lens, in which the lens is set so as to have the surface having a contact angle less than or equal to 100°, preferably less than or equal to 60° so that water attached on the surface is made into a form of a film. For this reason, the surface of the lens has high hydrophilicity, and if water droplets are attached when it is raining, the water droplets extend over the surface of the lens to form a water film. Thus, if mud or other attached matter is attached on the surface of the lens, it is possible to remove the attached matter without delay, and it is possible to always keep the surface of the lens in a clean state.

  • Patent number: 9092676
    Abstract: A solid object detection device detects solid objects in the periphery of a vehicle. A camera captures images including detection regions set in adjacent traffic lanes to the rear of the vehicle. A solid object assessment unit assesses whether or not a solid object is present in the detection regions. A lateral position detection unit detects a distance between the vehicle position and a dividing line that divides traffic lanes. A region setting unit enlarges the detection region on the side of the dividing line by a greater amount correspondingly with respect to an increase in the distance to the dividing line. A traffic lane change detection unit detects a traffic lane change made by the vehicle. Upon detecting a traffic lane change by the vehicle, a smaller enlarged amount is used when enlarging the size of the predetermined region outward in the vehicle-width direction.
