Modules 11 (right side) and 21 (left side), each of which integrates a control unit, for example, a millimeter wave radar of 24 GHz band that functions as means, are mounted. The hatched portion in the figure indicates an area where an obstacle can be detected by the millimeter wave radar of each module, and the size of the detection area is, for example, about 3 m × 3 m.

  The right module 11 is connected to the right door mirror 12 and the left module 21 is connected to the left door mirror 22 via a harness (not shown). The door mirror is related to an obstacle on the rear side based on the detection result by the millimeter wave radar. Information and information on abnormal state (failure etc.) of the rear side warning system are displayed. In addition, a switch unit 15 including a main switch for turning on / off the rear side alarm system of the vehicle according to the present embodiment is attached to the driver's seat side in the instrument panel, and an alarm buzzer for notifying the danger to an obstacle. Is also used as a buzzer 16 provided in an instrument panel meter.

  In the rear side warning system of the vehicle according to the present embodiment, the right module 11 and the left module 21 are connected according to a predetermined standard, for example, and perform mutual communication. Therefore, the inputs from the switch unit 15 and other sensors (not shown) need only be connected to one module.

  In addition, the rear side warning system of the vehicle according to the present embodiment is independent of other systems in the vehicle. When the main switch is turned on, the control units of the right module 11 and the left module 21 are described later. A predetermined process is executed.

<Control configuration of rear side warning system of vehicle>
FIG. 2 is a block diagram illustrating a control configuration of the rear side warning system of the vehicle according to the present embodiment. In the figure, the upper side shows the configuration related to the right module 11 and the door mirror 12, and the lower side shows the configuration related to the left module 21 and the door mirror 22, respectively.

  First, the structure regarding the right module 11 and the door mirror 12 is demonstrated. As an input to the right control unit 101 that controls the entire system, a main switch 111 for an occupant to operate ON / OFF of the rear side warning system of the vehicle, a right direction instructing a change of the traveling direction to the right side of the vehicle Indicator switch 112, a right rear radar 113 mounted on the right module 11 and functioning as a detecting means for detecting an obstacle on the right rear side, and a vehicle speed sensor for detecting the vehicle speed from the rotational speed of the wheel, for example. A signal from 116 is input.

  The main switch 111 is provided on the driver side of the instrument panel. When the passenger turns on the main switch 111 with the ignition switch turned on, the rear side warning system of the vehicle according to the present embodiment is activated. To do. However, as will be described later, the operation relating to the determination and display of the failure of the system starts when the ignition switch is turned on.

  In addition, the part related to the alarm display of the rear side alarm system of the vehicle according to the present embodiment is activated by turning on the main switch 111, but the actual operation is based on the signal from the vehicle speed sensor 116. Is determined to exceed a predetermined speed (for example, 10 km / h).

  In the right control unit 101, based on an input signal from the right rear radar 113, an obstacle determination unit 121 that determines the presence or absence of an obstacle approaching the host vehicle, a determination result of the obstacle determination unit 121, and a right direction instruction Whether to display an obstacle alarm according to the input signal from the vehicle speed sensor 116 and the determination result of the obstacle determination unit 121 that determines whether there is a dangerous obstacle based on the operation of the obstacle switch 112 An obstacle alarm buzzer ON / OFF determination unit 124 that determines whether to turn the alarm buzzer ON or OFF according to the determination results of the obstacle alarm display ON / OFF determination unit 123 and the risk determination unit 122 , A failure determination unit 125 that functions as an abnormality detection unit that determines whether or not there is a failure in the rear side warning system of the vehicle, and a BSD failure display (hereinafter simply referred to as a BSD failure display). "Fault indication" and determines BSD failure display ON / OFF determination unit 126 or also referred) to or OFF to ON is provided.

  In the present embodiment, each component in the right control unit 101 is described as independent. However, the right control unit 101 may be realized using a microcomputer or the like that executes arithmetic processing according to a predetermined program. . In that case, each component of the right control unit 101 is realized by a module corresponding to a program executed by the microcomputer.

  As an output from the right control unit 101, an obstacle alarm is displayed in the right door mirror 12 so as to notify the occupant that there is an obstacle to be aware of in accordance with the outputs of the obstacle determination unit 121 and the danger determination unit 122.

  2 is different in that the signals from the main switch 111 and the vehicle speed sensor 116 are not input to the left control unit 201 except for the configuration on the lower left module 21 and the door mirror 22 in FIG. Since it is the same as the structure regarding the module 11 and the door mirror 12, description is abbreviate | omitted. Further, as described above, the right control unit 101 and the left control unit 201 communicate with each other, and signals from sensors and switches that are input only to the right control unit 101 are also input to the left control unit 201 equally. .

  In FIG. 2, for the sake of convenience, the right direction indicator switch 112 and the left direction indicator switch 212 are shown separately, but the direction indicator corresponds to either the left or right direction depending on the direction in which the lever is tilted. It may be one component (part, assembly) that outputs the processed signal. In that case, when the left and right directions are instructed, a signal from the direction indicator may be input to the corresponding control unit.

  Similarly, FIG. 2 shows the right rear obstacle alarm buzzer 132 and the left rear obstacle alarm buzzer 232 separately. As described above, the buzzer 16 provided in the instrument panel meter both Also serves as. Therefore, in practice, the output signal from each control unit is connected to the buzzer 16 in parallel.

<Example of door mirror display>
FIG. 3 is a diagram illustrating a display example of the door mirror of the present embodiment with respect to the right door mirror 12. Since the same applies to the left door mirror 22, the description thereof is omitted.

  In FIG. 3, a right rear obstacle mirror alarm display unit 131 and a right mirror BSD failure display unit 133 are shown in the right door mirror 12. In this example, the alarm display unit 131 in the right rear obstacle mirror is provided in the vehicle width direction inside and below the door mirror 12, and the right mirror BSD failure display unit 133 is in the vehicle width direction outside and upward of the door mirror 12. It is provided in the part.

  Thus, when the right mirror BSD failure display part 133 is provided outside the door mirror 12 in the vehicle width direction, it is easy to see from the outside of the vehicle, for example, a vehicle traveling in an adjacent lane, and as necessary. Appropriate behavior can be induced.

  In this example, the mirror surface of the door mirror 12 is a half mirror, and a right rear obstacle mirror alarm display unit 131 and a right mirror BSD failure display unit 133 are provided inside the door mirror 12.

  The right rear obstacle mirror alarm display unit 131 can display an icon 1311 simulating a vehicle indicating the own vehicle and a segment column icon 1312 indicating a distance from the obstacle, and the obstacle alarm display ON / OFF If the determination unit 123 determines that the obstacle alarm display is to be performed, the segment corresponding to the distance between the icon 1311 and the obstacle is lit and displayed with a predetermined set luminance. When the danger judging unit 122 determines that there is a dangerous obstacle based on the judgment result of the obstacle judging unit 121 and the operation of the right direction indicator switch 112, that is, the vehicle from the right rear side. When an obstacle approaching the position is determined and the right direction indicator switch is turned on, a segment corresponding to the distance between the icon 1311 and the obstacle is flashed at a set brightness and a predetermined interval. The

  The right mirror BSD failure display unit 133 includes a light emitting unit 1331 that is determined to have a failure in the system by the failure determination unit 125 and is lit and displayed with a predetermined luminance in response to a signal for turning on the failure display. Yes.

  The configuration of the right rear obstacle mirror alarm display unit 131 and the right mirror BSD failure display unit 133 inside the door mirror 12 will be described in more detail with reference to FIG. FIG. 6 is a perspective view from above showing a schematic configuration of the door mirror 12 of this example. In the figure, the left side is the inside of the vehicle, and the right side is the outside of the vehicle.

  On the inner side of the mirror surface 130 of the door mirror 12, a segment row icon 1312 constituting the right rear obstacle mirror alarm display unit 131 and a light source 1313 such as an LED are provided. The light source 1313 is installed at a position where the light transmitted through the icon 1312 faces the driver inside the vehicle. That is, the alarm display unit 131 in the right rear obstacle mirror has a configuration in which directivity is directed toward the inside of the vehicle.

  On the other hand, on the vehicle exterior side of the mirror surface 130 of the door mirror 12, a light emitting unit 1331 and a light source 1332 and 1333 such as LEDs that constitute the right mirror BSD failure display unit 133 are provided. The light source 1332 is provided at a position where the light transmitted through the light emitting unit 1331 is directed toward the outside of the vehicle, and the light source 1333 is provided at a position where the light transmitted through the light emitting unit is directed toward the driver inside the vehicle. Yes. That is, the right mirror BSD failure display unit 133 has a configuration in which the directivity is extended to the vehicle outer side (vehicle width direction outer side).

  The light source 1313 and the light sources 1332 and 1333 are different in color. For example, the light source 1313 emits orange light, and the light sources 1332 and 1333 emit red light. Therefore, the occupant can easily identify the obstacle alarm display and the BSD failure display. Further, it is possible to identify that the BSD failure display is performed from outside the vehicle.

  As described above, in the present embodiment, the right mirror BSD failure display unit 133 is configured to widen the directivity of display outward in the vehicle width direction. For this reason, the failure display can be easily seen from the outside of the vehicle, for example, a vehicle traveling in an adjacent lane, and an appropriate action can be induced as necessary.

<Processing procedure of rear side warning system>
Next, the processing procedure of the rear side warning system in the present embodiment will be described with reference to the flowcharts of FIGS. In the following description, the processing by the right control unit 101 will be described, but the processing by the left control unit 201 is the same, and the description thereof will be omitted.

  FIG. 4 is a flowchart of processing related to the obstacle alarm display and the alarm buzzer by the right control unit 101.

  When the main switch 111 of the system is turned ON, a part related to the obstacle alarm display and alarm buzzer of the system is activated (step S1401). First, signal input from each sensor and switch is checked (step S1402). Then, it is determined whether or not the state of the failure flag (F) provided in the predetermined storage area is 1 (flag is set) (step S1403). If the failure flag is not set (F = 0), it is determined from the signal output from the vehicle speed sensor whether or not the vehicle speed exceeds a predetermined speed (10 km / h) (step S1404).

  If the failure flag is set in step S1403, or if it is determined in step S1404 that the vehicle speed does not exceed 10 km / h, the obstacle alarm display ON / OFF determination unit 123 displays the right mirror alarm obstacle alarm display. A signal for turning off the alarm display is output to the unit 131 (step S1412), and the process ends.

  On the other hand, if it is determined in step S1403 that the failure flag is not set and it is determined in step S1404 that the vehicle speed exceeds 10 km / h, the obstacle determination unit 121 outputs the right rear radar 113. The presence or absence of an obstacle in the detection area on the right rear side is determined from the received signal (step S1405). Subsequently, the obstacle determination unit 121 calculates the relative speed of the detected obstacle based on the change over time of the signal output from the right rear radar 113 (step S1406).

  Then, the obstacle determination unit 121 determines whether there is an obstacle approaching the host vehicle on the right rear side, that is, an obstacle to be noted from the calculation result in step S1406 (step S1407). If there is no obstacle to be noted, a signal for turning off the alarm display of the alarm display unit 131 in the right rear obstacle mirror is output (step S1413).

  If it is determined in step S1407 that there is an obstacle to be noted, a signal for lighting the alarm display is output to the alarm display unit 131 in the right rear obstacle mirror (step S1408).

  Next, the danger determination unit 122 determines from the signal output from the right direction indicator switch 112 whether the occupant has turned on the right direction indicator switch (step S1409). If the right direction indicator switch is OFF, the process is terminated as it is. On the other hand, if the right direction indicator switch is ON, the obstacle alarm buzzer ON / OFF determination unit 124 outputs a signal to sound the right rear obstacle alarm buzzer 132 according to the output from the danger determination unit 122 ( Step S1410). Moreover, the danger judgment part 122 outputs the signal which blinks an alarm display with respect to the alarm display part 131 in a right back obstacle mirror (step S1411), and complete | finishes a process.

  The process shown in FIG. 4 is repeatedly executed from step S1402 at a predetermined interval (for example, 200 msec) as long as the main switch 111 is ON.

  FIG. 5 is a flowchart showing a process related to failure display by the right control unit 101. The process shown in FIG. 5 is repeatedly executed at a predetermined interval (for example, 200 msec) independently of the process shown in FIG.

  As described above, the part relating to the determination and display of the failure of the present system is activated and starts operating when the ignition switch is turned on even if the main switch 111 is not turned on (step S1501). That is, in the present embodiment, the obstacle alarm display is performed when the vehicle enters a predetermined traveling state, while the display relating to the abnormal state is performed in other traveling states in addition to the predetermined traveling state. .

  According to this configuration, the frequency of the display regarding the abnormal state is increased, and a person outside the vehicle, such as an occupant of the own vehicle and an occupant of a vehicle traveling in an adjacent lane, is notified to the rear side warning system of the vehicle. It is possible to quickly grasp the abnormal state.

  First, it is determined whether or not the failure flag (F) is 1 (standing) (step S1502). If the failure flag is not set, the failure determination unit 125 determines whether there is a system failure (step S1503).

  Here, a failure determination method will be described. In this embodiment, (1) the intensity of the reflected wave received by the radar based on the signals output from the rear radars 113 and 213 is zero or excessive. (2) There is an error in the operation of one of the control units due to mutual communication between the left and right control units. (3) The lighting state of the alarm display units 131 and 231 in the rear obstacle mirror is abnormal. (4) When any of the four output signals from the vehicle speed sensor 116 is detected, it is determined that the system has failed.

  As a more specific example of detection for each item, regarding (1), it is practically impossible that the intensity of the reflected wave is zero for a predetermined time or more, so it is determined that the radar is abnormal. Further, for example, when the modules 11 and 21 of the present system are mounted in the rear bumper, the radar surface portion of the rear bumper is covered with a member that reflects radar waves (for example, a seal having a metal film). If this is the case, the intensity of the reflected wave always received by the radar will be excessive. Accordingly, even when the magnitude of the reflected wave received by the radar is excessive for a predetermined time or more, it is determined that the radar is abnormal. Regarding (2), a simple four arithmetic operation is requested from one control unit to the other control unit, and when the calculation result is incorrect, it is determined that the control unit is abnormal. Regarding (3), if the duration of lighting or blinking is abnormally long, it is determined that the alarm display unit is abnormal. As for (4), the speed obtained from the vehicle speed sensor 116 is compared with the speed calculated from the AT turbine speed, the engine speed, and the transmission gear ratio. It is determined that the sensor 116 is abnormal.

  If no system failure is detected in step S1503, the failure flag F is set to 0 (step S1504), and a signal is output to the right mirror BSD failure display unit 133 to turn off the BSD failure display (step S1503). S1505), the process is terminated. On the other hand, if a system failure is detected, a failure flag is set (1 is substituted for F) (step S1506), and the process ends.

  If it is determined in step S1502 that the failure flag is set, a signal is output to the right mirror BSD failure display unit 133 to light the failure display (step S1507), and the process is terminated.

  As described above, according to the present embodiment, both the indication relating to the obstacle on the rear side of the vehicle and the indication of the failure of the system are provided in the door mirror, so that there are few occupants during driving. It is possible to easily and reliably grasp the occurrence of a system failure by moving the line of sight. In addition, since the failure indication is arranged outside the door mirror in the vehicle width direction and the directivity of the display is spread outward in the vehicle width direction, the failure indication is outside the vehicle, for example, adjacent This makes it easy to visually recognize the vehicle traveling in the lane in which the vehicle is traveling, and can induce appropriate actions as necessary.

That is, the configuration related to the rear side warning system of the vehicle shown in the above embodiment is an example, and if it is a configuration capable of displaying an alarm for a rear side obstacle as intended by the present invention or displaying a failure of the system, It is not limited to these.

  For example, in the above embodiment, the obstacle alarm is displayed by an icon in the door mirror indicating that there is a rear side obstacle approaching the own vehicle, but the presence of the rear side obstacle, It is good also as a structure which displays the information regarding at least 1 of the distance of this, and the relative speed with the own vehicle by another method or aspect.

  Similarly, for the failure display, the light emitting unit in the door mirror is turned on. However, the failure display may be performed in another manner.

  Also, the obstacle alarm display unit and the failure display unit may be provided on portions other than the mirror surface of the door mirror (inside the mirror surface, around the mirror surface in the mirror housing, the outer periphery of the mirror housing, the mirror support column, etc.) good.

  Moreover, although the case where the alarm display of the obstacle is performed when the vehicle speed exceeds 10 km / h has been described as an example, the condition for performing the alarm display of the obstacle may be another condition. For example, when an obstacle to be watched is detected, or when an obstacle to be watched for is detected and the direction indicator is operated in the direction of the obstacle, an alarm display may be performed.

  Further, in the above embodiment, two light sources are provided so as to widen the directivity of failure display outward in the vehicle width direction. However, for example, the directivity is widened by using one light source and optical means such as a lens. You may do it.

  Furthermore, in the above embodiment, the configuration including two millimeter wave radars mounted on the rear right side and the rear left side of the vehicle as the detection unit has been described. However, if the detection unit has a desired detection area, Of course, other sensors such as radars and cameras may be used.

  Furthermore, the processing order described above with reference to the flowcharts of FIGS. 4 and 5 is merely an example, and the processing order may be changed as long as the functions required by the present invention are realized.
