When a position where the moving body stops is a slope, the control part performs control on the idle stop and predetermined control.

Description

  The present invention relates to a control device, and more particularly to a control device that performs control for safely idling stop on a slope.

  In recent years, intelligent transport systems (Intelligent Transport Systems, hereinafter referred to as “ITS”) aiming to solve road traffic problems such as traffic accidents and traffic jams by networking people, roads, and vehicles with information using information communication technology. Is being researched and developed. The form of wireless communication for automobiles in the field dealing with the safe driving support system in ITS can be broadly divided into road-to-vehicle communication and vehicle-to-vehicle communication. In road-to-vehicle communication, roadside machines and vehicles communicate information, whereas in vehicle-to-vehicle communication, vehicles directly communicate information.

  It is considered that information transmitted from the roadside unit to the vehicle by road-to-vehicle communication includes intersection information and traffic signal information. As intersection information, identification information for identifying the intersection, as traffic signal information, identification information for identifying the traffic signal, current signal display information of the traffic signal (information indicating the current display color of the traffic signal), current signal of the traffic signal Information such as the time until the display (display color of the traffic light) is changed to the next signal display, the next signal display information of the traffic light, and the like is included. And the apparatus which performs various controls using such intersection information and traffic signal information is proposed. For example, in consideration of environmental problems such as global warming, an increasing number of vehicles automatically stop idling, and devices that use intersection information and traffic light information at that time have been proposed.

  The control apparatus of the motor disclosed in Patent Document 1 is detected by a detecting unit that detects a time until the progress permission signal display (red) for the vehicle is switched to the progress permission signal display (blue), and is detected by the detection unit. Stop control execution means for executing stop control of the prime mover based on time. As a result, the engine is stopped when the time until switching from the progress disapproval signal display to the progress permission signal display is a predetermined time or more.

JP 2000-213388 A

  However, when the engine is stopped, auxiliary devices such as brake assist and a brake booster that enables the brake to be depressed with a light force stop operating. As a result, the brake pedal becomes heavier and cannot be depressed firmly, resulting in a problem that a sufficient braking effect cannot be obtained. In particular, on a slope, if the braking effect is not sufficiently obtained, the vehicle may collide with other vehicles existing on the downstream side by moving from the upstream side to the downstream side of the slope, so the above-mentioned patent document 1 is not suitable for idling stop on a slope.

  In view of the above-described problems, an object of the present invention is to provide a control device that performs control for safely idling stop on a slope.

  In order to achieve the above object, a control device according to the present invention is a control device that is provided in a moving body, and includes a control unit that determines whether or not the position where the moving body stops is a slope. Is characterized in that when the position where the moving body stops is on a slope, control regarding idling stop and predetermined control are performed.

  According to this configuration, when the moving body stops on a slope, predetermined control is performed so that idling can be safely stopped on the slope, so that it is possible to avoid dangers such as a collision with another moving body. .

  Further, in the control device having the above configuration, the control device includes a communication unit that receives information including at least traffic signal information, and the control unit is configured to display a signal of the traffic signal based on the traffic signal information as a progress non-permission signal display. The predetermined control is performed.

  According to this configuration, the predetermined control is performed so that idling can be safely stopped on the slope when the signal display of the traffic light is the progress non-permission signal display. Can be prevented from being controlled.

  In the control device configured as described above, the control unit does not perform the predetermined control when the time until the progress non-permission signal display switches to the progress permission signal display is less than a predetermined time. .

  According to this configuration, since the predetermined control is not performed when the time until the progress non-permission signal display switches to the progress permission signal display is equal to or shorter than the predetermined time, it is estimated that the stop time of the moving body is relatively short. Thus, it is possible to prevent predetermined control from being performed.

  In the control device configured as described above, the control device stores a current position detection unit that detects a current position of the moving body, a traveling direction detection unit that detects a traveling direction of the moving body, and map information. A map information storage unit, wherein the control unit specifies a traffic signal in front of the mobile body based on the current position, the traveling direction, and the map information, and the traffic signal is a traffic signal in front of the mobile body. It is desirable that

  In the control device having the above-described configuration, the predetermined control is to operate a parking brake.

  According to this configuration, since the parking brake is operated so that idling can be safely stopped on a slope, it is possible to avoid a danger such as a collision with another moving body.

  Further, in the control device having the above configuration, the control device includes a notification unit, and the predetermined control is to control the notification unit so as to notify that at least one of a foot brake and a parking brake is operated. It is characterized by.

  According to this configuration, in order to notify the driver of the moving body that at least one of the foot brake and the parking brake is operated so that idling can be safely stopped on a slope, there is a risk of collision with another moving body. It can be avoided. On the slope, it is generally considered that the foot brake is generally operated (the brake pedal is depressed). However, when the engine is in operation, the force to depress the brake pedal is amplified by the vacuum booster, so that the vehicle can be stopped without strongly depressing the brake pedal. On the other hand, if the engine stops, the vacuum booster will not operate, so the vehicle cannot be stopped unless the brake pedal is depressed firmly. On the other hand, since the brake pedal becomes heavy when the engine is stopped, it is difficult to depress the brake pedal strongly after the engine is stopped. Therefore, by encouraging the foot brake to be activated, the driver must depress the brake pedal strongly and activate the foot brake in advance (with the engine running and easy to depress the brake pedal strongly). Therefore, it is possible to avoid danger such as collision with another vehicle after the engine is stopped.

  In the control device having the above-described configuration, it is preferable that the control related to the idling stop is at least one of an engine stop and a notification that prompts the engine to stop.

  Further, in the control device having the above-described configuration, the control unit receives at least one of inclination information acquired by the inclination sensor, image information obtained by the image acquisition unit, and map information stored in the map information storage unit. It is desirable to determine whether or not the position where the moving body stops after being acquired is a slope.

  According to the present invention, when the moving body stops at a slope, predetermined control is performed so that idling can be safely stopped on the slope, so that it is possible to avoid dangers such as collision with other moving bodies. .

[First embodiment]
A first embodiment of the navigation device 20 of the present invention will be described with reference to FIG. It is a 1st flowchart which shows the flow of the process which the control part 1 of the navigation apparatus 20 of this invention performs.

  In step S01, the control unit 1 acquires vehicle information of the own vehicle. The vehicle information of the host vehicle is the current position of the host vehicle detected by the current position detection unit 4, the traveling direction of the host vehicle detected by the traveling direction detection unit 5, and the moving speed of the host vehicle detected by the speed detection unit 6. It is information including. Next, in step S02, the control unit 1 determines whether or not the own vehicle is stopped. If the own vehicle is not stopped (N in step S02), the process is terminated. If the own vehicle is stopped (Y in step S02), the process proceeds to step S03. “The host vehicle is stopped” means a state in which the moving speed of the host vehicle detected by the speed detector 6 is 0 km / h. In addition, when the moving distance detected by the distance sensor is 0 or when the current position detected by the GPS receiver is not moving (when the previous position and the current position are the same), the vehicle stops. May be determined.

  In step S03, the control unit 1 determines whether or not the position where the own vehicle has stopped is a slope. If the position at which the own vehicle has stopped is not on a slope (N in step S03), the process is terminated. If the position where the vehicle stops is a slope (Y in step S03), the process proceeds to step S04. In addition, the method in which the control part 1 determines whether the position which the own vehicle stopped is a slope is the own vehicle acquired by inclination sensors, such as a gyro sensor (or gyroscope) mounted in the own vehicle, for example. May be determined based on the inclination information of the vehicle, or may be determined by acquiring image information obtained by image acquisition means (not shown) such as an image sensor mounted on the host vehicle and performing image recognition processing. Also good. In addition, when the map information stored in the map information storage unit 7 includes information on a slope, the information on the slope may be acquired and determined, or stored in the map information storage unit 7. The determination may be made based on node data included in the map information (for example, based on an altitude difference between two nodes sandwiching the host vehicle). In the present embodiment, the slope (gradient) of the slope is not limited. If the slope is 0 degree or more, it may be determined that the slope is a slope, or when the slope is a predetermined slope or more. It may be determined as a slope.

  In step S04, the control unit 1 stops the engine and activates the parking brake. Conventionally known methods can be used for the system for automatically stopping the engine (the above-mentioned prior art document 1) and the system for automatically operating the parking brake. As a system that automatically activates the parking brake, when the predetermined time has elapsed since the vehicle stopped, or the shift position of the automatic transmission is set to the parking range or neutral range, and the brake pedal is depressed. There is a known system that automatically activates the parking brake when it is detected that the vehicle has started to move due to the parking brake not being sufficiently activated while the engine is stopped ( JP 2006-315607 A, JP 06-263016 A).

According to the present embodiment, the engine is stopped so that idling can be safely stopped on a slope, and the parking brake is operated, so that it is possible to avoid a danger such as a collision with another moving body. Note that, as in the present embodiment, the parking brake may be operated before stopping the engine, instead of stopping the engine and operating the parking brake.
[Second Embodiment]
A second embodiment of the navigation device 20 of the present invention will be described with reference to FIG. FIG. 3 is a third flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20. Note that steps S11 to S13 are the same as steps S01 to S03 of the first embodiment, and are omitted.

  In step S14, the control unit 1 controls the notification unit 10 to notify the driver of the own vehicle to stop the engine and to activate at least one of the foot brake and the parking brake. For example, there are a method of voice guidance “Please stop the engine and activate the parking brake”, and a method of displaying on the display unit 2 “Please stop the engine and depress the brake pedal strongly”. In the case of informing in more detail, it may be informed that “Because of the slope, please operate the parking (foot) brake and then stop the engine”. Thereby, the reason for operating the parking brake and the operating procedure can be notified to the user.

According to the present embodiment, the driver of the own vehicle is stopped so that idling can be safely stopped on a slope, or at least one of the foot brake and the parking brake is operated before the engine is stopped. Therefore, it is possible to avoid dangers such as a collision with another moving body.
[Third embodiment]
A third embodiment of the navigation device 20 of the present invention will be described with reference to FIG. FIG. 4 is a third flowchart showing the flow of processing executed by the control unit 1 of the navigation device 20. Note that steps S21 to S23 are the same as steps S01 to S03 of the first embodiment, and are therefore omitted.

  In step S24, the control unit 1 acquires the intersection information and the traffic signal information received by the communication unit 9. In addition, the timing which acquires intersection information and traffic signal information is not necessarily the said timing (after step S23). It may be acquired at the same time as the acquisition of vehicle information (step S21), or at the same time or separately from the acquisition of vehicle information, periodically or irregularly (based on the transmission timing of other communication devices). May be acquired. When information is acquired a plurality of times regularly or irregularly, the newest information may be used among the acquired information. Similarly, the timing for acquiring the vehicle information is not limited to the position in the flowchart, and may be acquired regularly or irregularly.

  In step S25, the control unit 1 determines whether or not the current signal display of the traffic light ahead of the host vehicle is a progress non-permission signal display (red signal). In order to determine whether or not the current signal display of the traffic light ahead of the host vehicle is a progress non-permission signal display, the control unit 1 first determines the current position of the host vehicle, the traveling direction of the host vehicle, and a map information storage unit. 7 is identified based on the map information stored in 7. Below, the identification method of the intersection ahead of the own vehicle is demonstrated. As described above, the map information storage unit 7 stores node data and link data. The node data is configured to include node number, node position coordinates (latitude / longitude), road type, node attribute indicating intersection information, intersection name, and the like, and the number of connection links and connection link numbers. The link data is configured to include link cost, road name, and traveling direction data including node numbers, road types, distances and / or required times, which are the start and end points of links. In addition to the above, link data includes data such as bridges, tunnels, railroad crossings, and tollgates as link attributes. That is, since the intersection information included in the node data includes information on the node number of the intersection and the position coordinates of the intersection, the control means 1 is where the vehicle is currently located (latitude / longitude) and in which direction. It is possible to identify the intersection ahead of the host vehicle by acquiring the vehicle (traveling direction).

  By identifying the intersection in front of the host vehicle, it is possible to identify that the traffic signal installed at the intersection is a traffic signal in front of the host vehicle, but when there are multiple traffic signals installed at the intersection It is necessary to specify which one of the plurality of traffic lights is the traffic light ahead of the own vehicle (whether the traffic signal is associated with the traveling direction of the own vehicle).

  Therefore, the method for identifying the traffic signal ahead of the host vehicle will be described next. Traffic signal information of an intersection predicted to arrive next based on the information (node number, latitude / longitude) of the intersection identified as an intersection ahead of the host vehicle and the intersection information received from the roadside unit by the communication unit 9 Is determined. The traffic signal information associated with the received intersection information including the same intersection position (latitude / longitude) as the identified intersection position (latitude / longitude) is determined as the traffic signal information of the intersection ahead of the vehicle. To do. That is, as described above, the traffic signal information includes each traffic signal number and signal display information associated with the approach direction to the intersection for each traffic signal installed at the intersection. Even if is installed, the route through which the vehicle enters the intersection (link number connected to the node corresponding to the intersection) and the traveling direction of the vehicle (which may be the traveling direction of the link) are obtained. By doing so, it is possible to specify which traffic signal signal display information needs to be acquired.

  In addition, when the map information stored in the map information storage 7 includes traffic signal identification information (a traffic signal number associated with a traffic signal position and identification and a traveling direction), the control unit 1 Based on the current position of the host vehicle, the traveling direction, and the map information, it is possible to identify a traffic signal (a traffic signal associated with the traveling direction of the host vehicle) installed at an intersection ahead of the host vehicle. .

  Note that all of the above methods for specifying the traffic signal ahead of the host vehicle specify the intersection in front of the host vehicle, and then specify the traffic signal installed at the intersection, but the vehicle does not specify the intersection. A traffic light in front of the vehicle may be specified. For example, when a roadside unit is installed for each traffic signal, and the traffic signal information (including the position of the traffic signal, the correspondence between the traffic signal and the current position of the vehicle and the traveling direction) is received from each roadside device, When there are multiple traffic signals associated with the current position and the direction of travel, the closest position (between coordinates) from the current position of the vehicle in the direction of travel of the vehicle (may be the travel direction of the road (link) that is running) Identify the traffic light (with a small distance) as the traffic light in front of your vehicle. In addition, when a roadside device with a narrow communication range is installed in front of a predetermined distance of the traffic light and the traffic signal information (signal traffic information) at the back of the predetermined distance is transmitted from the roadside device, the received traffic signal information May be determined as the traffic signal information of the next traffic signal (front traffic signal).

  In the following description, a traffic signal installed at an intersection is a traffic signal specified as described above. The control unit 1 stops the vehicle within a predetermined distance from the traffic signal (intersection) based on the map information or the position of the traffic signal (or intersection) received by the communication unit 9 in addition to the current position and traveling direction of the host vehicle. In the following description, it is assumed that the vehicle is stopped a predetermined distance before the traffic signal (intersection), that is, the vehicle is stopped by the signal display of the traffic signal. Do. From the traffic signal information received by the communication unit 9, the control unit 1 presents the traffic signal information of the traffic signal assigned the same number as the traffic signal number of the identified traffic signal (or the traffic signal information of the traffic signal having the same traffic signal position). Is obtained, and it is determined whether or not the current signal display of the traffic light ahead of the host vehicle is a progress non-permission signal display (step S25).

  If the traffic signal identification information is not included in the map information, the next intersection where the vehicle arrives next is identified based on the current position of the vehicle, the traveling direction, and the map information, and the position of the intersection (node position) ) And the position of the traffic signal included in the traffic signal information received by the communication unit 9, and if the distance difference is small, it is determined that the traffic signal is at the next arriving intersection. Based on the traffic signal information of the identified traffic signal (information associated with the traveling direction) and the traveling direction of the host vehicle (which may be the traveling direction of the road (link) that is running) Identify the traffic lights. And the information regarding the present signal display may be acquired from the traffic signal information of the specified traffic signal, and it may be determined whether or not the current signal display of the traffic signal ahead of the host vehicle is a progress non-permission signal display.

  If the signal display is not a progress non-permission signal display (N in step S25), the process is terminated. If the signal display is a progress non-permission signal display (Y in step S25), the process proceeds to step S26. In step S26, the control unit 1 performs predetermined control. The predetermined control is control performed by the control unit 1 in step S04 of the first embodiment or step S14 of the second embodiment, for example, control for stopping the engine and operating the parking brake, or self-control. For example, the vehicle driver may be informed that the engine is stopped and at least one of the foot brake and the parking brake is operated.

According to the present embodiment, the predetermined control is performed so that idling can be safely stopped on the slope only when the signal display of the traffic light ahead of the moving body is the progress non-permission signal display. It is possible to prevent the predetermined control from being performed in a situation where there is a high possibility that this will not occur.
[Fourth embodiment]
4th Embodiment of the navigation apparatus 20 of this invention is described using FIG. FIG. 5 is a fourth flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20. Note that steps S31 to S35 are the same as steps S21 to S25 of the third embodiment, and are therefore omitted.

  In step S36, when the signal display of the traffic light ahead of the host vehicle is the progress non-permission signal display, the control unit 1 determines whether or not the time until the progress non-permission signal display switches to the progress permission signal display is a predetermined time or more. (Or whether it is below). The time (hereinafter referred to as “remaining time”) until the progress permission signal display (red signal) is switched to the progress permission signal display (blue signal) is acquired at the same time as the information related to the current signal display of the traffic light described above is acquired. The If the remaining time is not longer than the predetermined time, in other words, less than the predetermined time (N in step S36), the process is terminated. If the remaining time is equal to or longer than the predetermined time (Y in step S36), the process proceeds to step S37. In step S37, the control unit 1 performs predetermined control.

  According to the present embodiment, when the signal display of the traffic light in front of the moving body is the progress non-permission signal display and the remaining time until the progress non-permission signal display switches to the progress permission signal display is a predetermined time or more. Since the predetermined control is performed so that idling can be safely stopped on the slope, it is possible to prevent the predetermined control from being performed in a situation where there is a high possibility that the vehicle must start immediately.

  In addition, this invention is applicable not only to said embodiment but other embodiment.

  For example, in the above-described embodiment, the predetermined control is a control for stopping the engine and operating the parking brake, or for stopping the engine for the driver of the own vehicle and at least one of the foot brake and the parking brake. Although described as control for notifying operation, the present invention is not limited to this. For example, the predetermined control may be control for operating a parking brake and control for notifying the engine to stop. In addition, it is good also as control which notifies to operate at least one of the control which stops an engine, and a foot brake and a parking brake. This content is applicable also to 1st Embodiment and 2nd Embodiment. In the above description, the predetermined control has been described uniformly. However, the control related to the idling stop such as the control for stopping the engine and the control for notifying the engine to be stopped as in Patent Document 1 described above. May be expressed as control relating to idling stop, and control for operating the parking brake, control for notifying at least one of the foot brake and the parking brake, and the like may be expressed as predetermined control. And when the stop position is a slope, the idling stop can be safely stopped on the slope by performing the control regarding the idling stop and the predetermined control.

  In addition, in the above embodiment, after stopping, it is determined whether or not the stopped position is a slope. However, the present invention is not limited to this. For example, the next position when arriving at the next intersection is determined. It is determined whether or not the signal display of the traffic light (the traffic signal ahead) is a progress non-permission signal display. When there is a slope, that is, when the position where there is a possibility of stopping is a slope, predetermined control may be performed. For example, this is control for notifying the driver of the own vehicle to stop the engine and activate at least one of the foot brake and the parking brake. Note that the above processing may be performed when it is determined that the progress non-permission signal is displayed, and when the remaining time is equal to or longer than a predetermined time, instead of the case where the progress non-permission signal is determined. It should be noted that after stopping the vehicle, the position where the vehicle stops is a slope, including the case where it is determined whether or not the position where the vehicle is stopped is a slope, and the case where it is determined whether or not the position where the vehicle is likely to stop is a slope. The expression of determining whether or not there is used is used.
