An apparatus for monitoring the immediate surroundings of a vehicle displays on a display within the vehicle cabin a captured image of the vehicle immediate surroundings captured by a camera mounted on a back door which can open and close. The apparatus determines whether the back door is open based on a signal output from a back door courtesy switch. If it is determined that the back door is open, a written notification that the back door is open is superimposed on the display showing the captured image from the camera. If it is determined that the back door is not open, the written notification is not shown.

Apparatus and method for monitoring the immediate surroundings of a vehicle

A front camera for filming an area stretching forwards is disposed in a front portion of a vehicle. A side camera for filming an area stretching laterally and diagonally forwards is disposed in a lateral-left portion of the vehicle. An indicator display that can be visually recognized by a driver is disposed in a compartment of the vehicle. An amount of change in the direction of the vehicle, that is, a deflection angle of the vehicle is detected on the basis of a vehicle speed and a steering angle of a steering wheel, which have been detected by means of various sensors. After the indicator display has started displaying a lateral photo image filmed by the side camera, the photo image displayed by the indicator display is shifted from the lateral photo image filmed by the side camera to a front photo image filmed by the front camera if the deflection angle has reached a predetermined angle.

Vehicle periphery monitor

A back camera image from a back camera mounted on a rear portion of a vehicle body is displayed on a display mounted on the console inside the vehicle cabin when the vehicle is parallel parking. After the vehicle passes a steering direction reversal point in this state, a corner camera image from a corner camera mounted on a corner portion of a front portion of the vehicle body is displayed on the display when the vehicle nears a vehicle parked in front, or, more specifically, when an angle of the vehicle after it has reached the steering direction reversal point has reached a predetermined value. Guidance images may be overlaid upon the camera images during some or all of the parallel parking maneuver.

Device for monitoring area around vehicle

Provided is a radar apparatus for use on a vehicle and for detecting one target or two or more targets present in a scan range by scanning the scan range with a radar beam, which has a means for obtaining prior target data by scanning the scan range with the radar beam, a grouping means for carrying out grouping of the prior target data according to a predetermined condition to obtain group data, and a target recognition means for identifying the group data and prior target data remaining without being grouped, as detection data corresponding to respective targets and carrying out recognition of each target corresponding to each detection data. The grouping means makes provision of a plurality of predetermined conditions, selects one condition or two or more conditions according to position information of prior target data to be grouped, and carries out the grouping based on the condition(s) selected. This radar apparatus for use on the vehicle can accurately perform the grouping of point data.

Radar apparatus for use on vehicle

An onboard radar system for a vehicle using the FM-CW method is provided. The radar system includes a mode changer. The mode changer provides a first mode which is suitable to detect a target existing distant from the vehicle. The mode changer also provides a second mode which is suitable to detect a target existing nearby the vehicle. The radar system detects a pair of beat frequencies in the first mode. Further, the radar system detects another pair of beat frequencies in the second mode. The radar system detects a target based on a pair of base beat frequencies which are determined based on an analysis result of both pairs of the beat frequencies.
