no. 1 Embodiment ＞

[0036] Hereinafter, the surrounding area warning device 1 for a vehicle according to the first embodiment of the present invention will be described with reference to the drawings. figure 1 This is an example of the system configuration of the surrounding area warning device 1 for a vehicle according to the first embodiment of the present invention. The surrounding area warning device 1 for a vehicle includes, as main components, another vehicle detection device 10 , a warning operation initiating device 20 , and an ECU (Electronic Control Unit) 30 for a surrounding area warning device.

[0037] In addition, in the following description, the vehicle equipped with the surrounding area warning device 1 for vehicles is called "own vehicle", and the vehicle which becomes a warning object is called "another vehicle."

[0038] [Another vehicle detection]

[0039] Another vehicle detection device 10 is, for example, a millimeter-wave radar device mounted inside the rear bumper of th...

no. 2 Embodiment ＞

[0086] Hereinafter, a surrounding area warning device 2 for a vehicle according to a second embodiment of the present invention will be described with reference to the drawings. The basic structure is the same as that of the first embodiment, so refer to figure 1 The description of the basic functions of each component is omitted.

[0087] [Another vehicle detection] is the same as the first embodiment, and description thereof is omitted.

[0088] [Alert Control]

[0089] The ECU 30 for the peripheral warning device according to the second embodiment does not expand and contract the warning area WA as in the first embodiment, but rotates the warning area so that the long side direction of the warning area WA is along the traveling direction of another vehicle. W.A.

[0090] Figure 14 This is an example of the warning area WA set by the ECU 30 for peripheral warning devices according to the second embodiment. As shown in the figure, the ECU 30 for a surrounding area warni...

no. 3 Embodiment ＞

[0094] Hereinafter, a surrounding area warning device 3 for a vehicle according to a third embodiment of the present invention will be described with reference to the drawings. The basic structure is the same as that of the first embodiment, so refer to figure 1 The description of the basic functions of each component is omitted.

[0095] [Another vehicle detection] is the same as that of the first embodiment, so the description thereof will be omitted.

[0096] [Alert Control]

[0097] In the peripheral guarding device according to the third embodiment, the ECU 30 sets a virtual guard line WL instead of the guard area WA, and activates the guard operation initiating means 20 when it is determined that another vehicle crosses the guard line WL within a predetermined time.

[0098] Figure 15 It is an example of the warning line WL set behind the host vehicle 100 . As shown in the illustration, the warning line WL is a line extending rearward from the side end of the host v...

Abstract

Provided is a vehicle periphery alert device which is mounted on a vehicle and which operates when the vehicle reverses from a parked state. The vehicle periphery alert device comprises: a sensing means for sensing a position and a progress direction of another vehicle which is present to the rear of the vehicle; an alert operation activation means for carrying out a prescribed alert operation in the vehicle; and a control means for setting a virtual alert range to the rear of the vehicle according to an angle formed by the progress direction of the vehicle and the progress direction of the other vehicle, and for operating the alert operation activation means when a condition including the position of the other vehicle being in the set alert region is satisfied.

Description

technical field [0001] The present invention relates to a peripheral warning device for a vehicle that is mounted on a vehicle and operates when the vehicle starts to reverse from a parked state. Background technique [0002] Conventionally, when the own vehicle moves backward from a state of being parked in advance, a device that issues an alarm or the like to another vehicle that may cross the own vehicle has been studied and put into practical use. In such a device, another approaching vehicle is detected by a millimeter-wave radar or the like, and when the other vehicle is traveling within a predetermined warning area based on the own vehicle, control such as emitting a warning sound is performed. [0003] However, when the vehicle is parked, it is not limited to parking at a right angle to the original travel area (including the normal travel road and the part outside the parking frame line of the parking lot where multiple vehicles can be parked). The possibility of p...
