Embodiment
Below, the best embodiment to drive assistance device of the present invention and method, at length describes with reference to accompanying drawing.
Fig. 1 means the block scheme of formation of an embodiment of drive assistance device of the present invention.In the figure, the drive assistance device 1 of present embodiment, is applied to utilize the teleseme information relevant with traffic signaling equipment the system of the stand-by period of teleseme (signal stand-by period) to driver's notice, and is equipped on vehicle.
Infrastructure information receiver 2 is to receive the machine be arranged at the infrastructure information that the infrastructure equipment (for example light beacon) on road sends.As infrastructure information, such as the road informations such as track formation, road width and road curvature that comprise the teleseme information such as teleseme form in traffic signaling equipment and signal cycle, road.
This car status surveillance sensor 4 is the sensors that monitor the state of this vehicle.Specifically, as this car status surveillance sensor 4, there is the side marker light sensor of the mode of operation of the vehicle speed sensor of the speed of a motor vehicle that detects this vehicle, the brake sensor that detects the ON state of detent, detection Direction indicator switch, the steering angle sensor of the steering angle of detection bearing circle etc.
Display part 5 shows the various information of the signal stand-by period information of this vehicle that comprises traffic signaling equipment place.Display part 5 can be instrument display screen etc., also can be integrated with guider 3.
ECU6 consists of the storeies such as CPU, RQM and RAM, input and output loop etc.ECU6 has could be by teleseme detection unit 7 and signal stand-by period notice control part 8.Could judge that this vehicle could pass through teleseme by teleseme detection unit 7.Signal stand-by period notice control part 8, by being judged to be this vehicle can not be by teleseme time by teleseme detection unit 7, determines the signal stand-by period of this vehicle and makes it to show at display part 5.
Fig. 2 mean by could be by the performed teleseme of teleseme detection unit 7 process flow diagram of the step by could determination processing.In the figure, first variable i is initially set to 0, variable j is initially set to 1, variable k is initially set to 1(step S51).
Then, obtain the teleseme information (step S52) being received by infrastructure information receiver 2.In teleseme information, comprise the form of traffic signaling equipment as shown in figure 3 (arrow lamp have it's too late quantity) and signal cycle as shown in Figure 4 (light color order and show number of seconds) etc.
Traffic signaling equipment 11 shown in Fig. 3 is to have teleseme main body (circle lamp) 12 and arrow lamp 13(is 2 here) the teleseme with arrow lamp.Signal cycle shown in Fig. 4, be configured to temporary transient (short time) bright light → red signal of green signal bright light → yellow signal bright light → red signal and temporary transient (short time) bright light → red signal of arrow lamp bright light → yellow signal bright light → red signal and arrow lamp bright light → yellow signal bright light → red signal bright light → green signal bright light ...In addition, the lighting time that red signal bright light refers to red signal for example, state more than threshold value (4 seconds), temporary transient (short time) bright light of red signal refers to that the lighting time of red signal is less than the state of threshold value.
Then, be extracted in the quantity N(step S53 of the red signal (not being the common red signal of the red signal of temporarily bright light: below, be called common red signal) comprising in signal cycle obtained in step S52).In the signal cycle shown in Fig. 4, the quantity N of red signal is 2 conventionally.
Then, judge whether common red signal exists (N > 0) (step S54), when common red signal exists, judge whether the signal lamp of j is green signal (step S55) before the common red signal of (N-i).When the signal lamp of j is not green signal before the common red signal of (N-i), variable j is rised in value, namely variable j is added to 1(step S56), return to step S55.Namely, until red signal signal lamp before becomes green signal conventionally, by order from back to front, review signal cycle.In the signal cycle shown in Fig. 4, before the 1st common red signal, the 8th signal lamp becomes green signal.
When the signal lamp of j is green signal when be judged as the common red signal of (N-i) in step S55 before, judge whether the light color of the round lamp of (j-k) before the common red signal of (N-i) is redness (step S57).When the light color of the round lamp of (j-k) is not redness before the common red signal of (N-i), variable k is rised in value (step S58), and return to step S57.In the signal cycle shown in Fig. 4, before the 1st common red signal below the 2nd of the green signal of 6(the) the red signal of temporary transient bright light become object.
When the light color of the round lamp of (j-k) is for redness before the common red signal that is judged as (N-i) in step S57, use following formula to calculate time R
n-1(step S59).This time R
n-1time till the common red signal that plays (N-i) from become at first the time point of red signal after green signal finishes (Fig. 4 with reference to).

1be be attached to the 1st common red signal can not pass through time, time R
2to be attached to can not passing through the time of the 2nd common red signal.
On the other hand, when being judged as common red signal not existing in above-mentioned steps S54, be judged to be and can pass through (step S63).
Fig. 5 means the process flow diagram of being controlled the step of processing by the performed signal stand-by period notice of signal stand-by period notice control part 8.
In the figure, first based on this car status surveillance sensor 4(specifically, vehicle speed sensor and brake sensor) detected value and the information of guider 3, judgement this vehicle of the traffic signaling equipment place of the teleseme information conforms with previously having obtained whether by could set by teleseme detection unit 7 can not be by the time in stopped (step S71).
When this vehicle has stopped within can not be by the time, as shown in (a) in Fig. 6, make to play and at display part 5, show successively (step S72) excess time that can not finish by the time till (green signal bright light) from the time point of this vehicle stop.Thus, can notify to the driver of this vehicle the stand-by period of signal accurately after this vehicle stop.
On the other hand, when this vehicles failed stops within can not be by the time, with similarly above-mentioned, judge this vehicle whether by could set by teleseme detection unit 7 can not start by the time before stopped (step S73).
When this vehicle had stopped before can not starting by the time, as shown in (b) in Fig. 6, make at display part 5, to show successively (step S74) excess time that can not finish by the time till (green signal bright light) from becoming to play by the time point of time.Thus, even if be for example green signal at teleseme, but can not be by the such situation of teleseme because preceding vehicle has stopped, the stand-by period of signal accurately that also time that becomes red signal from teleseme can being lighted be to driver's notice of this vehicle.
More than, infrastructure information receiver 2 and ECU6's could be by the step S52 in teleseme detection unit 7, the teleseme information that formation obtains the teleseme information relevant with traffic signaling equipment obtains unit.Could be by step S51, S53～S63 in teleseme detection unit 7, form based on teleseme information judge could be by traffic signaling equipment could pass through identifying unit.The signal stand-by period notice control part 8 of guider 3 and this car status surveillance sensor 4 and ECU6, forms based on determining to drive by the result of determination of identifying unit the auxiliary content determining means of auxiliary content.
Yet, in notify the system of such signal stand-by period to driver, just in the situation that red signal bright light notification signal stand-by period (excess time of red signal) when (also comprising red signal and arrow lamp bright light), notification signal stand-by period not when the yellow signal bright light of the then lighting lamp state of red signal and arrow lamp, so the time of notifying makes us changing giddily, easily make driver chaotic.In addition, because when red signal and arrow lamp bright light, notify the excess time of this state, so for the driver that will advance to the arrow lamp indicated direction in bright light, the time that notice can be passed through same as before, cause sometimes driver's impatience etc.
In addition, the notification signal in the situation that of the stand-by period not when at red signal and arrow lamp bright light, for the driver who does not advance to the arrow lamp indicated direction in bright light, although be equal to red signal, but why not also do not understand the notification signal stand-by period, thereby this driver easily feels inharmonious and chaotic.
On the other hand, in the present embodiment, be configured to, it is not the lighting time of pure red signal, also the lighting time of the lighting time of red signal and arrow lamp and the yellow signal followed therewith is also judged to be and can not be passed through, based on this result of determination, using until the excess time of green signal bright light as the signal stand-by period notify, so there is no the situation that the notified signal stand-by period makes us changing giddily.In addition, the impatience etc. that has suppressed the driver that will advance to the arrow lamp indicated direction in bright light.In addition, concerning the driver who does not advance to the arrow lamp indicated direction in bright light, because notified signal stand-by period and seldom feel inharmonious.By the above, the confusion of the driver in the time of can avoiding the teleseme of vehicle by with arrow lamp.
Fig. 7 means the block scheme of formation of the other embodiment of drive assistance device of the present invention.In figure, key element identical for the embodiment with above-mentioned or that be equal to is given same symbol, and the description thereof will be omitted.
In the figure, the drive assistance device 20 of present embodiment, be applied to utilize the information relevant with traffic signaling equipment and during with red signal not the mode of entering signal machine to driver, carry out the system of alarm, and be equipped on vehicle.
Fig. 8 means the process flow diagram of the step of being processed by the performed alarm control of alarm control portion 23.In the figure, the teleseme information based on being received by infrastructure information receiver 2 first, judgement is having or not (step S81) by being judged to be the possibility by traffic signaling equipment of this vehicle in the time that can not pass through by teleseme detection unit 7.Be configured to, when being judged as by could be judged to be the possibility by traffic signaling equipment of this vehicle in the time that can not pass through and do not have by teleseme detection unit 7 time, make alarm 21 produce alarm sounds (step S82).
On the other hand, when being judged as by being judged to be the possibility by traffic signaling equipment of this vehicle in the time that can not pass through sometimes by teleseme detection unit 7, teleseme information based on being received by infrastructure information receiver 2, whether the arrow lamp that craspedodrome direction is indicated in judgement in the teleseme with arrow lamp bright light (step S83).
When the arrow lamp that is judged as indication craspedodrome direction bright light, think that lighting time of arrow lamp of this craspedodrome direction of indication is for passing through, not make the mode of alarm sound generation control alarm 21(step S82).At this moment, also can be configured to, so long as there is the situation of a plurality of arrow lamps with the teleseme of arrow lamp, when the arrow lamp of indication craspedodrome direction bright light, not produce alarm sound.In addition, also can be configured to, consider number of track-lines and road width by the road after teleseme, so long as and road width identical with number of track-lines in other directions do not have the situation of large difference in craspedodrome direction, when the arrow lamp of indication craspedodrome direction bright light, do not produce alarm sound yet.
Think that in most cases vehicle is advanced to craspedodrome direction in intersection, still, when indicating the arrow lamp bright light of craspedodrome direction, do not make alarm sound produce, thus, the driver of the most vehicle that will advance to craspedodrome direction is not produced to unnecessary alarm.
When the arrow lamp that is judged as indication craspedodrome direction in step S83 is not during bright light, infrastructure information based on comprising the teleseme information being received by infrastructure information receiver 2, whether the arrow lamp of statistical ground judgement indication by the high direction of the predefined setting of likelihood ratio of the teleseme with arrow lamp bright light (step S84).
As the high direction of the likelihood ratio setting of the teleseme by with arrow lamp, there is the direction at the direction by the widest road of road width after teleseme and the maximum road of number of track-lines.For example, in the intersection shown in Fig. 9, left oblique direction accords with this.In addition, as the high direction of the likelihood ratio setting of the teleseme by with arrow lamp, while also having at least 1 bright light in a plurality of arrow lamps, become the arrow lamp indicated direction of normality lighting lamp state.For example, in the teleseme with arrow lamp shown in Figure 10, indicate the arrow lamp of craspedodrome direction to meet this.In addition, as the high direction of the likelihood ratio setting of the teleseme by with arrow lamp, can be set forth in do not have the lighting time of green signal with the longest arrow lamp indicated direction and privileged direction etc. of lighting time in the teleseme of arrow lamp.In addition, road width and number of track-lines etc. also can be obtained from the information of guider 3.
When being judged as the arrow lamp of indication by the high direction of the likelihood ratio setting of the teleseme with arrow lamp during bright light, think that lighting time of arrow lamp of this direction of indication is for passing through, not make the mode of alarm sound generation control alarm 21(step S82).
Like this, be configured to, higher by the probability of the teleseme with arrow lamp in indication statistics, and while there is the arrow lamp bright light of direction of the tendency that most drivers advances, do not make alarm sound produce, thus, most driver that will advance to this direction is not produced to unnecessary alarm.
In step S84, when being judged as the arrow lamp of indication by the high direction of the likelihood ratio setting of the teleseme with arrow lamp not during bright light, teleseme information, the information of guider 3 and the detected value of Ben Che status surveillance sensor 4 based on being received by infrastructure information receiver 2, whether the arrow lamp of the direction that judgement indication in the teleseme with arrow lamp is consistent with the travel direction of this vehicle bright light (step S85).
As the travel direction of this vehicle, the direction that the number of times that passes through in the resume that travel in the past such as there being the Route guiding direction of guider 3, in guider 3 is more and return to route direction from residence, in the situation that there is the dedicated Lanes direction of travelling on the road of dedicated Lanes etc.In addition, when by this car status surveillance sensor 4(specifically, side marker light sensor and steering angle sensor) when detecting driver and taking left or turn right action, this direction becomes the travel direction of this vehicle.At this moment, also can be at certain apart from do not find to the right before discrete time or turn action left in the situation that, the travel direction using craspedodrome direction as this vehicle.
When the arrow lamp that is judged as the indication direction consistent with the travel direction of this vehicle bright light, think that lighting time of arrow lamp of this direction of indication is for passing through, not make the mode of alarm sound generation control alarm 21(step S82).
Like this, be configured to, when the arrow lamp bright light of the consistent direction of the direction that will travel significantly with this vehicle of indication, do not make alarm sound generation, thus, the driver of this vehicle that will advance to this direction is not produced to unnecessary alarm.
When the arrow lamp that is judged as the indication direction consistent with the travel direction of this vehicle in step S85 is not during bright light, so that the mode of alarm sound generation is controlled alarm 21(step S86).Namely, be configured to, when in the situation that have by being judged to be the possibility by traffic signaling equipment of this vehicle in the time that can not pass through by teleseme detection unit 7, arrow lamp by arrow lamp, the indication of the high direction of the likelihood ratio setting of the teleseme with the arrow lamp direction consistent with the travel direction of this vehicle in the arrow lamp of indication craspedodrome direction, indication statistics all not during bright light, makes alarm sound generation.
In the above description, the alarm control portion 23 of ECU22, forms based on determining to drive by the result of determination of identifying unit the auxiliary content determining means of auxiliary content.The statistical information of statistical information of travel direction that infrastructure information receiver 2 and guider 3 are configured for obtaining the vehicle of the crossing intersection part that is provided with traffic signaling equipment obtains unit.Guider 3 and this car status surveillance sensor 4 are configured for detecting the travel direction detecting unit of the travel direction of this vehicle.
As described above, in the present embodiment, be configured to, it is not the lighting time of pure red signal, also the lighting time of the lighting time of red signal and arrow lamp and the yellow signal followed therewith is also judged to be and can not be passed through the time, based on this result of determination, to there being the driver of the vehicle of the possibility that enters intersection when the red signal to carry out alarm, thus, can alleviate the inharmonious sense that driver feels.
At this moment, be configured to, even by being judged to be and can not passing through by teleseme detection unit 7, in the situation that the arrow lamp of the indication craspedodrome direction arrow lamp bright light of situation, the indication of the bright light direction consistent with the travel direction of this vehicle of the arrow lamp by the high direction of the likelihood ratio setting of teleseme in the situation, indication statistics of bright light, do not carry out the alarm for driver yet, thus, can more alleviate driver's inharmonious sense, carry out feeling that with driver's driving the driving conforming to is auxiliary.
By above explanation, the confusion of the driver in the time of can avoiding the teleseme of vehicle by with arrow lamp.
In addition, as the alarm unit for driver, not being limited to especially above-mentioned alarm sound, can be also alarm demonstration etc.
