摘要： A visibility condition determining device for a vehicle has a lighting device, an in-vehicle camera and an image processing unit. The lighting device is mounted on the vehicle and irradiates an outside of the vehicle with its light beam. The in-vehicle camera picks up an image including a transmission space through which the beam irradiated from the lighting device is transmitted in an imaging area, and including a non-irradiated area that is not directly irradiated with the beam in a background of the transmission space in the image. The image processing unit determines a visibility condition outside of the vehicle based on a brightness of the non-irradiated area in the image which is picked up by the in-vehicle camera when the lighting device irradiates outside of the vehicle.

摘要： A symbolizing execution section symbolizes information regarding driving scenes, and describes an entire driving scene around the location of an own motor vehicle. This makes it possible to only increase the information to be symbolized when the number of traffic participants is increased. This can adopt the increase of the traffic participants. A symbol transition prediction section predicts a transition of the symbolized driving scene by using influence which affects the operation of the traffic participants caused by the operation of the own motor vehicle. This makes it possible to increase prediction accuracy while decreasing a large amount of calculation on predicting the transition of driving scene.

摘要： A radar wave reflected by a preceding automotive vehicle is received. The distance and the reception level of the received radar wave are repeatedly stored with relation therebetween. The reception levels are plotted with respect to distance. The distribution of the receptions levels is approximated with a linear equation as the characteristic of the radar apparatus. Variation in the distribution, that is, Y intercept of the linear equation represents the variation of the characteristic of the radar apparatus. A reference characteristic of the radar is measured with changing the distance to the preceding reflective object and the measured characteristic is measured with a moving preceding vehicle during actual traveling. The reference Y intercept is compared with the measured Y intercept to detect the deviation. Further, the divination amount or the measured value is classified to judge the cause of decries in the characteristic using conditional signals.

摘要： A road surface reflection detecting apparatus includes a road recognition unit for recognizing a road in a picture taken by a camera of a road existing in front of a vehicle. A road surface reflection detection unit extracts a picture from the road recognized by the road recognition unit and determines the degree of reflection of light from the surface of the road based on the picture extracted from the road. The picture includes the reflection of light beam radiated from vehicle headlights. If the reflection is determined to be high, the direction or intensity of the light beam from the vehicle headlights is regulated.

摘要： Provided is a radar apparatus capable of continuously and stably making a detection of a target even if a reflected wave from a target already detected falls into obscurity due to the presence of low-frequency noises or reflected waves from other targets. An estimated value of information on a target to be obtained when the target is detected in the present cycle are acquired from the target detected in a previous cycle. When a peak compatible with the estimated value is detected in only one of a frequency-rising section and a frequency falling section of a radar wave, if the frequency of the non-detected peak pertains a low-frequency noise domain or if a side-by-side travel flag is set with respect to the target detected in the previous cycle, the non-detected peak is considered as buried by low-frequency noises or peaks of other targets, and a peak pair corresponding to the detected target is extrapolated.

摘要： A vehicle-mounted radar apparatus which periodically derives and registers successive momentary position values for a target object such as a preceding vehicle based on received reflected radio waves and derives final lateral position data by smoothing the momentary position data, judges when a degree of scattering of the registered momentary position values exceeds a first predetermined level and in that case derives corrected position data based on differences between envelope curve line values which are generated based on local extreme values of the momentary position data, and performs smoothing of the corrected position data instead of the momentary position data, to obtain the final lateral position data. If the target object is not estimated to be located directly ahead of the host vehicle along a straight route, the corrected position data are adjusted in accordance with relative positions and orientations of the target object and host vehicle.

摘要： The invention provides a signal process apparatus for an on-vehicle radar and a method thereof that can reduce operation load and obtain a sufficient detection capability. According to information on a detected object, the invention registers as peak data a frequency BIN contained in a frequency region around a prediction peak that is to be detected on a distance power spectrum. The invention predicts a running line on which a predetermined vehicle runs, obtains a power spectrum along the running line, and registers as peak data the peak of the power spectrum. Then, the invention averages the distance power spectrum obtained for each channel, registers as peak data the peak of the averaged distance power spectrum, and only with regard to the registered peak data (frequency BIN), seeks a directional power spectrum.

摘要： In a vehicle headlight apparatus, a projection unit having a same structure of an LED projector receives a light provided from a lamp. The projection unit generates and projects a projection image toward a vehicle front-area. A vehicle ECU has an image signal obtaining means for obtaining image signals representing a vehicle front-area image, a high brightness area determination means for analyzing the image signals in order to successively determine a high brightness area in the image signals, and a projection image determination means for determining a projection image so that the light, corresponding to the high brightness area and to be irradiated toward the vehicle front-area, becomes weak when compared with the light previously determined. Thereby, an intensity of the light to be irradiated to an object with a high reflection factor can be decreased. This can suppress decreasing of driver's frontal visibility.
