Description

  The present invention relates to a vehicle notification device that notifies a state of a wiper provided in a vehicle.

  Generally, a vehicle is provided with a wiper device for wiping rain and snow that has fallen on a windshield. This wiper device includes a front wiper provided in a front windshield (front glass) of a vehicle and a rear wiper provided in a rear windshield (rear glass) of the vehicle.

  As disclosed in Patent Document 1, these wiper devices are held in a wiping state in which the wiper blade wipes the windshield while urging the windshield at a desired pressure, and the wiper blade is lifted up and held away from the windshield. It is possible to switch between the lockback state to be performed.

Japanese Patent Laid-Open No. 2006-7921

  The lockback state described above is used for preventing the wiper blade and the windshield from sticking due to freezing or preventing the wiper blade from being damaged due to snowfall in an environment where the amount of snowfall is large. However, forgetting to return from the lockback state to the wiping state may occur, and even if the wiper device is operated in the lockback state, it is not possible to wipe off rain and snow that has fallen onto the windshield. In particular, since the rear wiper is difficult to enter the field of view when traveling, it is difficult to notice that the rear wiper remains in the lockback state.

The control unit causes the notification unit to notify that the lockback state is set.

The vehicle alarm device according to the present invention includes:
A travel speed input means for inputting the travel speed of the vehicle;
When the control means is in the lockback state and the traveling speed of the vehicle exceeds a predetermined speed, the control means causes the notification means to notify that it is in the lockback state.
It is preferable to configure as described above.

The vehicle alarm device according to the present invention includes:
Comprising an operation input means for inputting an operation state of the wiper;
The control means is in the lockback state, and when the wiper is operated to swing, the swinging operation of the wiper is stopped.

  ADVANTAGE OF THE INVENTION According to this invention, the display apparatus for vehicles which alert | reports the state of the wiper apparatus with which the vehicle was equipped appropriately can be provided.

BRIEF DESCRIPTION OF THE DRAWINGS The structure schematic of the alerting | reporting apparatus for vehicles which is embodiment of this invention. The processing procedure figure of the alerting | reporting apparatus for vehicles.

  A vehicle notification apparatus M according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the vehicle notification device M mainly includes a lockback state input unit 1, a vehicle information input unit 2, a notification unit 3, and a control unit 4.

  The lockback state input means 1 detects whether the state of the rear wiper provided on the rear windshield of the vehicle is a wiping state or a lockback state by a switch or the like, and outputs it to the control means 4. Specifically, a switch that is turned on when the rear wiper is biased to the rear windshield at a desired pressure and turned off when the rear wiper is separated from the rear windshield detects the lockback state of the rear wiper. The information is input to the control means 4.

  The vehicle information input means 2 is, for example, an in-vehicle network such as a controller area network. The vehicle information input means 2 outputs various vehicle information (vehicle running speed, engine speed, rear wiper operation switch information) input from various controllers of the vehicle to the control means 4. That is, the vehicle information input means 2 is a travel speed input means for inputting the travel speed of the vehicle, or an operation input means for inputting the operation state of the rear wiper.

  The notification means 3 is, for example, a liquid crystal display that visually notifies information by an image.

  The control means 4 is, for example, a circuit board on which an arithmetic integrated circuit such as a microcontroller is mounted. The control unit 4 causes the notification unit 3 to notify various vehicle information input from the vehicle information input unit 2 as a meter image. Further, the control unit 4 causes the notification unit 3 to notify the state of the rear wiper based on information input from the lockback state input unit 1 or the vehicle information input unit 2.

  Next, a procedure for notifying the state of the rear wiper will be described with reference to FIG.

  When the ignition switch of the vehicle is turned on and activated, the control means 4 starts a procedure for informing the state of the rear wiper in order from step S1.

(Step S1)
The control unit 4 determines whether or not the state of the rear wiper input from the lockback state input unit 1 is the lockback state. If the rear wiper is in the lockback state, the process of step S2 is executed. If the rear wiper is in the wiping state, the process ends.

(Step S2)
The control unit 4 determines whether or not the vehicle traveling speed input from the vehicle information input unit 2 is equal to or higher than a predetermined traveling speed (for example, 5 km / h). When the vehicle traveling speed is equal to or higher than the predetermined traveling speed, the control unit 4 determines that the vehicle is in a traveling state, and executes the process of step S3. If not, the process ends.

(Step S3)
The control means 4 informs the notification means 3 that the rear wiper is in the lockback state, and that the windshield cannot be wiped correctly even if the rear wiper is swung in this state. Specifically, as shown in the message MSG1, the notification means 3 displays an image of “the rear wiper is in a lockback state. The rear wiper does not function correctly”.
The control means 4 performs the process of step S4 after performing notification of the message MSG1 for a predetermined time (for example, 3 seconds).

(Step S4)
Based on the rear wiper operation switch information input from the vehicle information input unit 2, the control unit 4 determines whether or not the rear wiper has been swung. When it is determined that the swing operation of the rear wiper has been performed, the control unit 4 executes Step S5. Otherwise, step S4 is executed periodically.

(Step S5)
When the rear wiper is swung, the rear wiper is in the lockback state. Even if the rear wiper is swung in this state, the rear wiper is idled and the windshield glass cannot be wiped correctly. Therefore, the control means 4 stops the swinging operation of the rear wiper by outputting a motor operation stop signal to a wiper device (not shown).
Further, the control means 4 displays that the rear wiper swinging operation has been stopped. Specifically, as shown in the message MSG2, the notification means 3 displays an image of “the rear wiper is in a lockback state. The swing of the rear wiper has been stopped”.
The control means 4 terminates the process after executing the notification of the message MSG2 for a predetermined time (for example, 3 seconds).

The vehicle notification device M according to the present invention has been described above. The vehicle notification device M according to the present invention includes a notification unit 3, a lockback state input unit 1 for inputting a lockback state of the wiper, and a control unit 4 for controlling the notification unit 3. The notification means 3 is configured to notify that it is in the lockback state.
By configuring in this way, it is possible to reduce the possibility that the wiper forgets to return from the lockback state to the wiping state.

Further, the vehicle notification device M according to the present invention includes travel speed input means 2 for inputting the travel speed of the vehicle, the control means 4 is in a lockback state, and the travel speed of the vehicle has a predetermined speed. If it exceeded, it was comprised so that the alerting | reporting means 3 might alert | report that it was a lockback state.
With this configuration, the lockback state is not notified when the vehicle is stopped such as during a car wash, and the wiper can be notified of forgetting to return from the lockback state to the wiping state at an appropriate timing.

Further, the vehicle notification device M according to the present invention includes an operation input means 2 for inputting an operation state of the wiper, and the control means 4 is in a lockback state, and when the wiper is swung, The rocking motion is stopped.
By comprising in this way, consumption of useless motive power can be suppressed.

  The present invention is limited by the above-described embodiments, and modifications may be made to the above-described embodiments within the scope according to the gist of the present invention.

  Specifically, the present invention can be applied to a front wiper.

  Moreover, although this invention showed embodiment which alert | reports that a wiper is a lockback state, when a vehicle will be in a driving | running | working state, it is not limited to this. Specifically, it may be a notification that the wiper is in the lockback state when the ignition of the vehicle is turned on and the vehicle is activated. Alternatively, a notification may be made when an operation for running the vehicle is detected, such as when the vehicle door is unlocked and the driver gets on the vehicle.
