A warning output device includes a rear sensor unit and an electronic control unit. The electronic control unit is configured to, when a shift position is an R range, based on information from the sensor unit indicating that a first obstacle is detected, output a warning for informing an occupant of the presence of the first obstacle, in a first state, output first predetermined warning display and first predetermined warning sound; and in a second state, output second predetermined warning display and second predetermined warning sound. The ECU is configured to, in the second state, output the second predetermined warning sound for a predetermined time, then stop the output of the second predetermined warning sound, and output the second predetermined warning display for a longer time than the second predetermined warning sound.

An image processing device according to an embodiment includes a display control unit, a pattern specification unit, and a pattern collating unit. The display control unit generates a composite image that is a surrounding image of a vehicle viewed from a virtual viewpoint, based on images input from in-vehicle cameras, and displays thereof on a display unit. The pattern specification unit specifies an image pattern to be output as the input image among image patterns, for each in-vehicle camera. The pattern collating unit determines whether all image pattern responses from the in-vehicle cameras match with the image pattern. The display control unit displays a certain preparation image on the display unit when the display switching condition to the composite image is satisfied, and displays the composite image thereon instead of the preparation image, when the pattern collating unit determines that all the image pattern responses match with the image pattern.

When a first object is first detected during a second display process executed when a second object is detected, a vehicle display control apparatus of the invention starts a first display at a first detection of the first object, stop the first display at a termination of the second display process and start the first display process at a start of the next second display process.

A vehicle driving assist apparatus executes a vehicle collision prevention control when a target object distance from a vehicle to a target object is equal to or smaller than a predetermined distance. The apparatus acquires the target object distance on the basis of a position of the target object in a camera image taken by a camera and a height of the camera in a situation that a movable load of the vehicle is a maximum load capacity.

A method for adjusting an outside mirror of a vehicle includes providing at least one seat position sensor, a driver position detector and a mirror actuator. The position of the driver's seat is determined with the at least one seat position sensor. An angular orientation of the outside mirror is adjusted with the mirror actuator based on the determined position of the driver's seat such that a rear of the vehicle is visible in the outside mirror. Thereafter, a location of a driver's head may be determined with the driver position detector when the driver is seated in the driver's seat. The angular orientation of the outside mirror is readjusted with the mirror actuator based on the detected position of the driver's head such that a rear of the vehicle is visible in the outside mirror when the driver is seated in the driver's seat.

A driver advisory system for previewing the local traffic conditions on a highway is described. Apparatus according to an embodiment of the present invention includes an advisory system that transmits information regarding the status of the host vehicle to drivers of other vehicles, in particular when the status of the host vehicle presents a hazardous condition to other vehicles. The advisory system may also receive information from other vehicles, and provide an alert to the driver of the host vehicle if a hazardous condition exists.

A reflection-point estimation section constituting an object detection apparatus first calculates a rotational correction angle for each estimated reflection point Pby using the following equation, using the fact that the ratio of the amount of change in a detected distance dto a movement amount Iof a sonar is nearly equal to a tangent with respect to the direction normal to the surface of an object:Rotational correction angle&#x3c6;=tan {()/}in which n is a natural number. Subsequently, the reflection-point estimation section obtains estimated reflection points P' after correction, by rotating each estimated reflection point Pbased on the calculation result.

A point-sequence approximation apparatus determines whether a proportion of a straight-line approximation region is high as compared to that of a curve approximation region. In addition, if it is determined that the proportion of the straight-line approximation region is high as compared to that of the curve approximation region, the point-sequence approximation apparatus repeatedly performs random setting of a candidate of an approximation straight line, and evaluation of approximation accuracy of the candidate of the approximation straight line based on distances between the candidate of the approximation straight line and the points constituting the point sequence. Moreover, the point-sequence approximation apparatus performs straight-line approximation by using the candidate of the approximation straight line with the best result of evaluation of the approximation accuracy as an approximation straight line.

A system for assisting the alignment of a hitch pin mounted on the rear of a vehicle with a hitch socket mounted on the front of a trailer. The system includes a camera mounted to the vehicle and positioned to capture an image rearwardly of the vehicle. A video display is contained within the vehicle which displays the image captured by the camera. A processor is also contained in the vehicle which calculates a preferred path of travel of the vehicle to position the hitch pin in alignment with the hitch socket. The processor is programmed to provide instructions to an operator of the vehicle of the required steering to maintain the vehicle on the preferred path of travel. The processor recalculates the preferred path of travel whenever the vehicle veers from the preferred path of travel by a preset threshold.

In a parking support device, a distance measuring unit measures a quantity equivalent to a distance from an automotive vehicle to an object existing in a predetermined direction. A storage unit stores a sequence of points indicating results of the measurement performed multiple times. A first object specifying unit generates first object information based on the sequence of points when a length of the sequence of points has exceeded a first reference length. A second object specifying unit generates second object information based on the sequence of points when a length of the sequence of points has exceeded a second, larger reference length. A target parking position is determined based on the first object information in a stage where the first object information is generated.

Parking support device

A method and apparatus for determining the position of an object relative to a moving vehicle. While the vehicle is moving in a first direction, successive sensor pulses are transmitted from a vehicle sensor and toward the object. The echo or reflection from the sensor pulse is then received while a processor determines the transit time between the transmission of each pulse and the receipt of its echo. An angle factor is then calculated which represents the difference between the elapsed time of two sequential sensor pulses and the distance traveled by the vehicle between those two pulses. Whenever the absolute value of the angle factor exceeds a preset threshold, an angle is selected from a predefined lookup table contained in memory. Conversely, when the absolute value of the factor is less than the preset threshold, the angle is calculated as a function of the factor. The distance is then calculated between the sensor and the object as a function of the angle and the transit time for the sensor pulse and the appropriate signal is provided to the occupant of the vehicle.
