- the road surface state is predicted for each of the above-described geographical units through which the planned traveling route passes, based on, for example, the weather information and the road information on the planned traveling route acquired in step S208.
- the predicted road surface condition may be stored in association with the geographical position. For example, information on a frozen road surface or a snowy road may be obtained directly from weather information or road information, or may be predicted from air temperature or weather.
- a road whose temperature is included in an area below the freezing point can be predicted as a frozen road surface, and a general road in an area where there is snowfall more than a predetermined amount can be predicted as snow coverage.
- there is no travel environment that affects automatic driving anywhere on the travel route, and the road surface condition, that is, the travel environment. can be expected to be good.
- the traveling environment including the road surface condition can be specified based on, for example, external environment information acquired by the outside sensor and vehicle condition information acquired by the inside sensor. For example, if the entire road surface is white by image recognition of an image taken by the camera 41, it can be determined that the road is a snowy road. If the temperature below freezing (or the temperature below freezing and below a predetermined temperature) is detected as the current outside temperature by the outside air temperature sensor, it may be determined that the road surface is frozen.
- the ghost when a ghost is detected by the rider 42 or by both the rider 42 and the radar 43, the ghost can be estimated to be the winding up of snow due to traveling on a snowy road, and also in this case it can be determined as a snowy road surface.
- the friction coefficient of the road surface can be estimated together with the throttle opening degree at which the slip occurs and the brake depression force at which the skid occurs.
- the yaw rate and the lateral acceleration can be detected by a sensor, and the lateral rate can be detected by comparing the yaw rate and the lateral acceleration obtained from the velocity and the steering angle of the vehicle.
- the degree of the coefficient of friction of the road surface can be estimated from the speed at which the side slip occurs and the steering angle. If the estimated friction coefficient of the road surface is smaller than a predetermined threshold, it can be determined that the current road surface is a low friction coefficient (low ⁇ road).
- the traveling environment in the planned traveling route identified in step S212 includes a predetermined traveling environment that is considered to affect automatic driving, as in the example described above (S214).
- the predetermined traveling environment is a traveling environment that can affect automatic driving, and in addition to low ⁇ roads such as frozen roads and snow roads, for example, visibility of external sensors such as snow blowing and fog becomes short. You may include the situation.
- a message prompting the driver to input whether or not to re-search the traveling route is displayed by the input / output device 9, and the input thereto is the traveling route. It is determined whether or not it is a re-search of (S216). If a re-search is instructed, the process branches to step S202.
- the input / output device 9 allows the driver to have a predetermined traveling environment on the planned traveling route, that is, affect the automatic driving. Report that there is a sex (S218).
- This notification may include, in addition to a message simply indicating the possibility, a message that allows the driver to select whether or not to perform the automatic driving.
- a predetermined time is set in the timer possessed by the ECU 20, measurement thereof is started (S222), and input by the driver for the message is awaited.
- the automatic driving mode is set (S220).
- Level 3 (second level) achieves the highest level automatic operation. For example, the driver does not have to operate at all for driving, steering, or braking, and furthermore, it is not necessary to prepare for takeover to manual operation (hands off-eye off).
- Level 2 (first level) realizes lower level automatic operation than level 3. For example, the driver does not have to operate for driving, steering, or braking, but must monitor messages from the vehicle, for example, and be prepared for takeover from automatic driving to manual driving (hands off-eyes on).
- Level 1 of automatic driving is, for example, automatic driving more limited than level 2, such as follow-up driving on a freeway.
- step S214 If it is determined in step S214 that there is a predetermined traveling environment on the planned traveling route, the process may branch to step S218 without executing the route search again in step S216.
- step S218 of FIG. 2 the procedure of FIG. 3 is executed by the ECU 20 when there is an input thereto or the timer set in step S222 expires. If the driver has not entered a response to the notification and the predetermined time has expired, the automatic driving mode of the selected level is set. This is because the driver who has left without responding to the notification from the vehicle 1 may not be aware of the notification and may expect traveling in the automatic driving mode.
- a level is provided for the automatic operation, so if the predetermined time has expired, the level of the automatic operation is first set to a high level (for example, the highest level that can be set such as level 3) or a low level For example, it is determined whether the level is a lower level such as level 2) (S302). This determination may require the driver to have an input for selecting a level, for example, and may make a determination based on that, or may be determined based on a preset reference. If it is determined that the level to be set is not the highest level, the level 2 automatic operation mode is set (S304). On the other hand, if it is determined that the level is the highest level, the level 3 automatic operation mode is set (S306).
- the automatic operation level to be set may be limited by the amount of rainfall or snowfall or visibility. For example, based on the weather information etc. acquired from the server, if it is a predetermined amount of rainfall (the amount of rainfall of XX mm or more), dropping the highest level of automatic operation that can be set from level 3 to level 2 When entering, the maximum level may be set to level 2 or the like. Thus, the level of automatic operation to be set may be limited according to the environment.
- step S300 When the driver inputs a response to the notification, it is determined whether to set the automatic driving mode based on the input (S300). If there is an input indicating that the automatic operation mode is not set, the process is ended without setting the automatic operation mode (ie, in the manual operation). In this case, driving of the vehicle is performed by the driver after this. On the other hand, when an input indicating that the automatic operation mode is to be set is input, the process branches to step S302. The rest is as described above. However, when the level of automatic driving is input as a response to the notification, step S304 or step S306 may be executed according to the designated level to set the automatic driving mode.
- the planned travel route to the destination set before the start of travel includes a portion of the predetermined travel environment, that is, before the start of travel by automatic driving (that is, in advance), To the driver. Then, the driver provides an opportunity to indicate the intention, and sets the automatic driving mode according to the intention.
- the driver is notified that there is a predetermined traveling environment regardless of where the predetermined traveling environment appears on the planned traveling route.
- the corresponding place is far from the present position. Therefore, when the corresponding place is separated by a predetermined distance or more from the current position, the information of the place and the fact that there is a predetermined traveling environment are stored, and the automatic driving mode is set once to start traveling. You may Then, when the position of a certain distance (or time) is reached to the corresponding place, the driver may be informed that there is a place of a predetermined traveling environment. Also in this case, the process for the notification is as described above.
- the automatic operation mode may be switched whether to set the automatic operation mode or not. In this case, when the predetermined time in FIG. 3 has expired or when there is an input for setting the automatic operation mode, the automatic operation mode may be set.
- ⁇ Control procedure at the time of automatic driving As shown in FIGS. 2 and 3, it is determined whether the current traveling environment is a predetermined traveling environment or not while the traveling environment is determined in advance while the traveling by automatic driving is performed. On a continuous basis. Thus, even when the predetermined traveling environment can not be predicted in advance, it can be determined that the predetermined traveling environment is actually present.
- the procedure is shown in FIG.
- the procedure of FIG. 4 is also executed by the ECU 20.
- the procedure of FIG. 4 is executed periodically or periodically, for example, while traveling in automatic driving. Alternatively, it may be executed each time the vehicle travels a predetermined distance.
- the repetition cycle may be variable according to the setting or may be fixed in advance. The cycle may not be as frequent as, for example, one minute, five minutes, or ten minutes.
- the repetition cycle may be relatively low, for example, 1 km, 5 km, 10 km, and so on.
- it may be performed more frequently if there is rainfall or snowfall, and less frequently if it is sunny.
- external environment information is acquired from an external sensor (S400).
- the communication device 24c may be used to acquire the external information.
- the external information to be acquired may be, for example, weather information or road information of an area including the current position.
- the current traveling environment is specified based on the acquired external environment information (and also the external information, if any) (S402).
- the predetermined travel environment may be the same as described for FIG. If it is determined that it corresponds, the driver is notified of the possibility of affecting automatic driving (S406), measurement of a predetermined time is started using a timer (S408), and input by the driver is awaited.
- step S400 external information such as weather information and road information acquired via the communication device 24c may be acquired for the planned traveling route that will travel in the future, as in FIG.
- the external information to be acquired may be, for example, related to the area scheduled to travel after a predetermined time from the present time, and based on it, the predicted travel environment after the predetermined time may be specified.
- FIG. 5 shows a processing procedure by the ECU 20 when there is an input by the driver or when a predetermined time has elapsed. First, it is determined whether the input is an input for continuing the automatic driving (S520). If it is determined that the input is to continue, the process ends without performing anything.
- the current level of the automatic driving is determined (S522). If the current level is a high level (for example, level 3), the level of the automatic driving is transitioned to a low level (for example, level 2) (S524). At this time, it is desirable to notify the driver to lower the level of the automatic driving. If it is determined in step S522 that the current level is a low level (for example, level 2), the automatic operation mode is ended, and the mode is switched to the manual operation mode (S526). This is a so-called takeover, and it is desirable to notify the driver of the takeover and to request an input for confirmation of the takeover.
- the automatic operation mode when the automatic operation mode is continued, the automatic operation is continued as it is, but otherwise, the level of the automatic operation is controlled to be lowered. If a predetermined time has elapsed without a response to the notification performed in step S408, the processing ends without performing any particular processing assuming that continuation of the automatic driving is selected. However, in this case, there is also a possibility that the driver has not noticed the notification, so that notification to continue the automatic driving may be further performed.
- FIG. 5 it is described in FIG. 5 that there are two levels of automatic operation levels, if there are three or more levels, manual operation will be taken over if the current level is at the lowest level, and levels will be lowered at higher levels. You may control as follows.
- step S404 of FIG. 4 when it determines with the present driving
- an external sensor such as the camera 41, the radar 42, or the rider 43, although it may be determined that the weather or the surrounding traveling environment has significantly changed.
- the traveling environment is not classified into two values such as a predetermined traveling environment and other traveling environments, and evaluated in at least three or more stages. For example, when the stages are “good running environment”, “intermediate running environment”, and “predetermined running environment”, the time when the “good running environment” transitions to the “intermediate running environment”, The time difference with the time of transition from the "intermediate traveling environment” to the "predetermined traveling environment” is determined. If this time difference is smaller than a predetermined value, it may be judged as an abrupt change.
- FIG. 6 also shows another example of the processing procedure by the ECU 20 when there is an input by the driver or when a predetermined time has elapsed.
- the level of automatic operation either automatic operation is continued or take-over to manual operation is performed.
- S500 it is determined whether the input is an input to continue automatic driving (S500). If it is determined that the input is to continue, the process ends without performing anything. On the other hand, when it is determined that the input is not for continuing the automatic operation, the automatic operation mode is ended, and the mode is switched to the manual operation mode (S502). Also in this case, it is desirable that notification of takeover to the driver and request for confirmation of takeover be performed.
- step S408 If a predetermined time has elapsed without a response to the notification performed in step S408, the processing ends without performing any particular processing assuming that continuation of the automatic driving is selected. However, in this case, there is also a possibility that the driver has not noticed the notification, so that notification to continue the automatic driving may be further performed. In this way, when the automatic operation mode is continued, the automatic operation is continued as it is, but otherwise the automatic operation is canceled.
- the present embodiment it is possible to determine that there is a predetermined traveling environment on the planned traveling route by the above configuration and procedure, and when it is determined that there is a predetermined traveling environment, the driver is notified beforehand Can be notified. And the opportunity for a driver to determine the driving mode according to the information can be provided. Furthermore, it is possible to determine that the vehicle is in a predetermined traveling environment while traveling, and when it is determined that the vehicle is in a predetermined traveling environment, it is possible to notify the driver of the fact. And the opportunity for a driver to determine the driving mode according to the information can be provided.
- a first aspect of the present embodiment is a vehicle control device for controlling the traveling of a vehicle, Environment specifying means for specifying a traveling environment of the vehicle; A control unit configured to control the traveling of the vehicle according to the traveling environment specified by the environment specifying unit when the automatic driving mode is set; And output means for notifying the driver, The control means determines whether the traveling environment is a predetermined traveling environment, and when it is determined that the predetermined traveling environment is determined, the output means outputs a notification of the result of the determination. It is characterized by With this configuration, it can be determined that the traveling environment is a predetermined traveling environment, and the driver can be notified of the result of the determination.
- the traveling environment includes the state of the vehicle detected by the vehicle state detection means and the outside of the vehicle detected by the external detection means State and / or external information obtained via communication means
- the environment identification means determines that the predetermined traveling environment is based on at least one of a state of the vehicle included in the traveling environment, a state outside the vehicle, and the external information. It is characterized by With this configuration, it is possible to determine that the vehicle is in the predetermined traveling environment based on at least one of the state of the vehicle and the external information.
- the third aspect of the present embodiment further includes input means for receiving an input by the driver,
- the control means outputs, as the notification, an inquiry as to whether or not to set the automatic operation mode, and an input according to the notification is not made within a predetermined time after the output of the notification, or
- an instruction to set an automatic operation mode is input, the automatic operation mode is set.
- setting the automatic operation mode newly sets the automatic operation mode when the automatic operation mode is not set. And continuing the automatic operation mode when the automatic operation mode is already set.
- the determination of the predetermined traveling environment can be performed before the automatic driving mode is set, or can be performed during traveling in the automatic driving mode.
- the fifth aspect of the present embodiment is characterized in that the automatic operation mode has a first level and a degree of driver's intervention lower than the first level. Including two levels,
- the control means determines that the traveling environment is the predetermined traveling environment while controlling the traveling of the vehicle in the automatic driving mode of the second level, the control means is used as an input for the notification.
- the automatic operation mode is transitioned to the first level based on that. With this configuration, automatic driving can be performed at a lower level in a predetermined traveling environment.
- the sixth aspect of the present embodiment further includes setting means for setting a traveling route in advance,
- the control device acquires the external information on the traveling route set via the communication unit, and the traveling environment in the traveling route is the predetermined. It is characterized by judging whether it is a driving environment.
- the control device sets the automatic driving mode to set the automatic operation mode when the travel route is set in advance. Before starting travel control, it is determined whether or not the travel environment on the travel route is the predetermined travel environment, and notification according to the result of the determination is performed. With this configuration, it is possible to set a traveling route prior to traveling, and to determine in advance whether there is a predetermined traveling environment in the set traveling route.
- the level of automatic driving determines the maximum vehicle speed permitted at that level and the user-set vehicle speed. Therefore, according to the control of the automatic driving of the present embodiment, by detecting the change of the traveling environment, the maximum vehicle speed permitted at each level is limited, or the user-set vehicle speed is reduced.
- a transition may be made from a hands-off mode in which the driver holds the steering wheel off while maintaining the lane to a hands-on mode in which the driver holds the lane while holding the steering wheel.

Abstract
L'invention concerne un dispositif de commande de véhicule qui détermine si un environnement de déplacement prescrit, tel qu'une route d'essai à faible frottement, est présent sur un itinéraire de déplacement planifié lorsqu'une conduite autonome est démarrée, et détermine également si l'environnement de déplacement prescrit est présent sur un itinéraire de déplacement courant ou sur le trajet de déplacement planifié pendant la conduite autonome. Lorsque l'environnement de déplacement prescrit est présent, le dispositif de commande de véhicule notifie la présence au conducteur. Lorsque le conducteur ordonne l'instauration de la conduite autonome en réponse à la notification, la conduite autonome est nouvellement instaurée dans un cas dans lequel la conduite autonome n'a pas encore été démarrée, et la conduite autonome continue dans un cas dans lequel le véhicule circule dans un état de conduite autonome. Lorsque le conducteur n'ordonne pas l'instauration de la conduite autonome, une conduite manuelle prend le dessus ou une commande autonome de niveau inférieur est instaurée.
