  ADVANTAGE OF THE INVENTION According to this invention, the glass wiping apparatus for vehicles which can operate the wiper and the glass heating apparatus, and can remove efficiently the ice and snow which adheres to glass can be obtained.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a system configuration diagram showing an embodiment of a vehicle glass wiping apparatus according to the present invention. As shown in FIG. 1, the vehicle glass wiping apparatus of the present embodiment is configured with a control ECU 10 as the center. The control ECU 10 is configured by a microcomputer, like other ECUs, for example, a CPU, a ROM for storing control programs, a readable / writable RAM for storing calculation results, a timer, a counter, an input interface, and an output. It has an interface etc.

  The control ECU 10 is connected to the glass heating device 40 and the wiper 42 via an appropriate bus such as a CAN (controller area network). The control ECU 10 controls the operation of the glass heating device 40 and the wiper 42.

  The glass heating device 40 is an appropriate defogger (heat ray) set on substantially the entire surface of the vehicle glass (typically the rear glass), or an appropriate glass (typically the front windshield) that does not obstruct the field of view. It includes a deaiser (hot wire) set in a part (for example, a peripheral part), a defroster that ejects warm air (hot air generated by a heater core that is a component of an air conditioning system) toward glass, and the like.

  Although not shown, the wiper 42 includes a wiper blade that slides to wipe the glass surface, a wiper arm that holds the wiper blade, an electric motor that moves the wiper arm (hereinafter referred to as a wiper motor), and a wiper arm and a wiper motor. Link mechanism. The present invention is not particularly limited to the configuration of the wiper 42 but can be realized by the existing general wiper 42.

  A GPS receiver 50, a communication device 52, and various sensors 54 are connected to the control ECU 10 via an appropriate bus. The control ECU 10 acquires information such as the external environment around the vehicle position through communication with the GPS receiver 50, the communication device 52, and various sensors 54.

  The power management ECU 20 is connected to the control ECU 10 via an appropriate bus. As will be described later, the power management ECU 20 controls power distribution to each on-vehicle electric load including the heating device 40 and the wiper 42.

  Various electronic components including the glass heating device 40, the wiper 42, and the ECUs 10 and 20 are supplied with power from the battery 60 or a generator (alternator) via an electric wire (not shown). The battery 60 includes a lead battery, a lithium ion battery, a fuel cell, and the like, and may have a single power supply configuration or a dual power supply configuration.

  A local communication device 70 is connected to the control ECU 10 via an appropriate bus. The local communication device 70 receives a signal (hereinafter referred to as “boarding notification signal”) notifying the user of boarding from the remote operation device 80 possessed by the user. As will be described later, the control ECU 10 responds to the boarding notification signal from the remote operation device 80 and realizes pre-operation of the glass heating device 40 and the wiper 42 as necessary. The remote operation device 80 realizes communication with the local communication device 70 by a dedicated wireless method or local communication means such as Bluetooth built in a mobile phone.

  Next, with reference to FIG. 2 and subsequent figures, the preliminary operation of the glass heating device 40 and the wiper 42 realized when the boarding notification signal is received from the remote operation device 80 will be described in detail.

  FIG. 2 is a flowchart showing a flow of characteristic operations or processes executed by the vehicle glass wiping apparatus of the present embodiment. FIG. 3 is an explanatory view showing stepwise how the ice and snow on the glass are removed by the vehicle glass wiping apparatus of the present embodiment.

  First, when the boarding notification signal is received from the remote operation device 80 as described above, as step 100, the control ECU 10 acquires the current position information of the vehicle from the GPS receiver 50, and sets the current vehicle position as the external environment around the vehicle position. Understand the surrounding weather and climate. The current vehicle position information may be the final vehicle position (stored in the memory) detected when the vehicle is used last time. As a result, a load for calculating the current position of the vehicle can be avoided and, in particular, in a state before the engine is started (that is, in a state where there is no power generation by the generator), a slightly wasteful power consumption can be avoided. Alternatively, as the current position information of the vehicle, position information of the remote operation device 80 that can be included in the boarding notification signal from the remote operation device 80 may alternatively be used. Such a configuration is useful when, for example, the GPS receiver 50 is not mounted on the vehicle.

  The external environment around the vehicle position is useful information for estimating the adhesion state of frost, snow, and ice (hereinafter collectively referred to as “ice and snow”) on the glass. 40 and the wiper 42 are used as one parameter for determining the operation mode of the wiper 42.

  In this step 100, the control ECU 10 may grasp the external environment in consideration of information from various sensors 54 such as an outside air temperature sensor, an inside air temperature sensor, a humidity sensor, and a solar radiation sensor mounted on the vehicle. Further, the control ECU 10 grasps the external environment around the vehicle position in consideration of area-specific weather information (snow cover information and temperature information) that can be acquired from the information providing center, FM multiplex broadcasting station, or the like via the communication device 52. May be.

  In the subsequent step 110, the control ECU 10 estimates and determines whether or not the ice / snow adhesion state on the glass is equal to or greater than a predetermined reference based on the external environment around the vehicle position grasped in the step 100. When it is determined that the ice / snow adhesion state on the glass is not equal to or greater than the predetermined standard, it is determined that the ice / snow removal by the operation of the glass heating device 40 and the wiper 42 is unnecessary, and the process is terminated. On the other hand, when it is determined that the ice / snow adhesion state on the glass is equal to or greater than the predetermined standard, it is determined that the ice / snow removal by the operation of the glass heating device 40 and the wiper 42 is necessary, and the process proceeds to step 120.

  In step 120, the control ECU 10 grasps the scheduled boarding time of the user. The user's scheduled boarding time is also used as one parameter for determining the operation mode of the glass heating device 40 and the wiper 42 as will be described later. This is because the glass heating device 40 and the wiper 42 are operated using the electric energy from the limited battery 60 so as to ensure an appropriate field of view when the user boarding, in accordance with the scheduled boarding time of the user. This is because the operation mode of the heating device 40 and the wiper 42 is the most efficient.

  In step 120, the scheduled boarding time of the user may be estimated based on the position information and speed information of the remote operation device 80 itself included in the boarding notification signal from the remote operation device 80. That is, the scheduled boarding time of the user is estimated based on the distance between the remote operation device 80 and the vehicle (that is, the distance from the user's vehicle) and the moving speed of the remote operation device 80 (that is, the moving speed of the user). It's okay. Alternatively, an appropriate button is set on the remote operation device 80, and the boarding notification signal from the remote operation device 80 may include the user's scheduled boarding time information (for example, information notifying how many minutes will arrive). Good.

  In the subsequent step 130, the control ECU 10 secures a field of view necessary for boarding the user based on the external environment around the vehicle position grasped in the step 100 and the estimated boarding time of the user grasped in the step 120. Thus, the operation mode of the glass heating device 40 and the wiper 42 is determined.

  Here, the operation modes of the glass heating device 40 and the wiper 42 include an operation start timing and an operation output.

  The operation start timing of the glass heating device 40 is basically the same as the reception of the boarding notification signal from the remote operation device 80. However, when it is estimated that the amount of ice and snow on the glass is small and there is a relatively long time until the scheduled boarding time of the user, an appropriate time has elapsed since the reception of the boarding notification signal from the remote operation device 80. The operation of the glass heating device 40 may be started later (that is, from a predetermined time before the user's scheduled boarding time).

  The operation output of the glass heating device 40 is basically constant. However, for the glass heating device 40 with variable operation output, the more severe the external environment around the vehicle position is (for example, the amount of snow accumulation is more severe). It is good also as operating with a big operation output, so that a user's boarding scheduled time is short, so that it is large or temperature is low. In the configuration in which a plurality of glass heating devices 40 (for example, deisa and defroster) exist for one glass, the operation output of the glass heating device 40 is changed by changing the number of the glass heating devices 40 to be operated. May be.

  The operation start timing of the wiper 42 is determined in association with the operation of the glass heating device 40 as described in detail below.

  FIG. 3 is an explanatory diagram relating to a method for determining the operation start timing of the wiper 42, and is a diagram showing stepwise how ice and snow on the glass are removed by the vehicle glass wiping apparatus of this embodiment.

  As shown in FIG. 3A, in a state where ice and snow are attached to the glass, the ice and snow on the glass can be removed by operating the glass heating device 40 to melt the ice and snow by heat. However, when only the glass heating device 40 is used, it may take a long time to completely remove the snow and snow when there is a large amount of adhesion, and it may take a considerable amount of time to secure a field of view where the vehicle can be operated. In addition, enormous electrical energy is consumed by the glass heating device 40, and the battery capacity may be excessively reduced.

  On the other hand, even if the wiper 42 is operated to scrape off the snow and ice from the glass with the wiper 42 in a state where the amount of snow and snow is attached, the snow and snow becomes a weight and the wiper arm cannot be moved. Is wasted.

  Therefore, in this embodiment, as shown in FIG. 3B, the wiper 42 is operated at an operation start timing at which ice and snow on the glass melted by the operation of the glass heating device 40 can be scraped off from the glass. The That is, when the glass heating device 40 is operated, the ice and snow on the glass starts to melt from the vicinity of the glass surface due to the heat generated by the glass heating device, the adhesion to the glass surface is lost and the glass surface is easily detached and the volume is increased. The resistance as a weight with respect to the movement of the wiper arm is reduced. That is, the ice and snow covering the entire surface of the glass melts and accumulates at the lower end of the glass. When the wiper 42 is operated at such timing, as shown in FIG. 3C, ice and snow on the glass can be easily scraped off from the glass.

  From this point of view, the control ECU 10 predicts the time when the ice / snow adhesion amount falls below a predetermined threshold based on the ice / snow adhesion amount on the glass predicted in step 110 and the work amount (generated heat amount) of the glass heating device 40. The time is determined as the operation time (operation timing) of the wiper 42. Here, the threshold value for the amount of ice and snow attached is the amount of ice and snow that can be scraped off by the wiper 42, and may be derived / adapted by experiment or simulation (calculation based on the operating torque of the wiper 42). It may be adapted by learning during operation of the wiper 42. The work amount of the glass heating device 40 can be calculated based on the operating mode of the glass heating device 40 determined as described above.

  Further, the operation output of the wiper 42 is basically constant, but the wiper 42 capable of varying the operation output (wiper arm driving torque) is severe if the external environment around the vehicle position is severe. The closer the user's scheduled boarding time is, the shorter the user's scheduled boarding time (for example, the greater the amount of snow accumulation or the lower the temperature), the greater the operation output may be.

  In step 140, the control ECU 10 operates the glass heating device 40 and the wiper 42 according to the operation mode determined in step 130. At this time, the control ECU 10 notifies the power management ECU 20 of the operation modes of the glass heating device 40 and the wiper 42 determined in step 130.

  In step 150, is the power management ECU 20 capable of supplying power that can realize the operating modes of the glass heating device 40 and the wiper 42 determined as described above based on the storage state (SOC) of the battery 60 as determined? Judge whether or not. That is, the power management ECU 20 determines whether or not the electric power that can be supplied from the battery 60 exceeds the electric power necessary to realize the operation mode of the glass heating device 40 and the wiper 42 determined as described above. The storage state of the battery 60 may be detected based on the current value or voltage value of the battery 60, the battery temperature, or the like. The electric power that can be supplied from the battery 60 is determined so that at least the electric power necessary for starting the engine (that is, starting the starter motor) remains sufficiently.

  In step 150, when the electric power that can be supplied from the battery 60 exceeds the electric power required to realize the operation mode of the glass heating device 40 and the wiper 42, the power management ECU 20 There is no particular restriction on the power supply to the wiper 42 (step 160). Thereby, the glass heating device 40 and the wiper 42 are operated according to an operation mode (operation output or operation timing) instructed from the control ECU 10.

  On the other hand, when the power that can be supplied from the battery 60 is lower than the power necessary to realize the operation mode of the glass heating device 40 and the wiper 42 in step 150, the process proceeds to step 170.

  In step 170, the power management ECU 20 limits the power supply to the glass heating device 40 and the wiper 42 so as to be within the range of power that can be supplied from the battery 60. For example, when the power that can be supplied from the battery 60 is insufficient, the power supply to the wiper 42 may be limited so that only the operation of the glass heating device 40 is realized. In addition, when the power that can be supplied from the battery 60 is not sufficient, the number of operations of the wiper 42 is reduced and, for example, the initial operation timing of the wiper 42 is delayed, and the first operation of the wiper 42 (the power consumption for one time). It may be ensured that the above-mentioned snow scraping is successful.

  In this step 170, the control of the supply power distribution by the power management ECU 20 can be realized mechanically by connecting / cutting off the power supply path to the glass heating device 40 and the wiper 42 by a relay, for example. By changing and blocking the control signal for 42, it can be easily realized electrically.

  Thus, according to the present embodiment, by causing the glass heating device 40 and the wiper 42 to cooperate, ice and snow on the glass can be efficiently removed with less electrical energy. In addition, the ice / snow adhesion state on the glass is predicted based on the external environment around the vehicle position, and accordingly, the operation mode of the wiper 42 in cooperation with the operation mode of the glass heating device 40 is determined. It is possible to efficiently remove ice and snow on the glass while preventing unnecessary power supply to the wiper 42 which becomes inoperable due to the weight of the glass.

  In addition, according to the present embodiment, since the operation modes of the glass heating device 40 and the wiper 42 are determined in accordance with the user's boarding, the limited visual energy can be used efficiently, and a desired field of view can be obtained when the user boardes. Can be secured. In addition, since the operation mode of the glass heating device 40 and the wiper 42 is determined in consideration of the state of the battery 60, it is possible to prevent an excessive decrease in the battery capacity.

  In this embodiment, it is also possible to predict the ice / snow adhesion state on the glass (determining the operation mode of the wiper 42) using parameters other than the external environment around the vehicle position. For example, it is possible to estimate the range of glass covered with ice and snow based on a solar radiation sensor (light sensor) that detects the amount of light incident from the glass, and from the same point of view, the scenery outside the vehicle through the glass It is also possible to detect the range of the glass covered with ice and snow based on the captured image of the in-vehicle camera that captures the image.

  Next, with reference to FIG. 4, a method for determining the operation timing of the wiper 42 for the second time and thereafter will be described.

  As shown in FIG. 4, when the first operation of the wiper 42 is performed according to the operation timing determined as described above (step 200), the control ECU 10 determines whether or not the first operation of the wiper 42 has been successfully completed. Is determined (step 210). For example, in a configuration in which PWM (Pulse Width Modulation) control that adjusts the output of the wiper motor with a duty ratio is performed, the wiper motor rotor does not rotate even when the duty exceeds a predetermined number or a current exceeds a predetermined number. May be determined that the operation of the wiper 42 has not been completed successfully by stopping energization of the wiper motor.

  If the first operation of the wiper 42 has been successfully completed, it is determined that the operation of the wiper 42 has succeeded in scraping snow on the glass (see FIG. 3C) (step 220). In this case, if necessary, the second and subsequent operations may be executed in a relatively short period until the snow on the glass is completely wiped off. However, the second and subsequent operations may be set lower in priority than the operation of the glass heating device 40, and may be limited when the power that can be supplied from the battery 60 is not sufficient as described above.

  On the other hand, if the first operation of the wiper 42 has not been completed successfully, that is, the wiper arm of the wiper 42 has not moved at all due to the weight of ice or snow, or the wiper arm has moved, but at the full stroke. If it cannot move (becomes unable to move from the middle), it is determined that the first operation timing of the wiper 42 is too early, so that the snow scraping on the glass is unsuccessful (step 230). In this case, the process proceeds to step 240.

  In step 240, the resistance received by the wiper at the time of the unsuccessful operation of the wiper is calculated, and the amount of ice and snow on the glass is re-predicted based on the resistance. Here, the resistance received by the wiper when the wiper is activated is increased by the weight of ice and snow acting on the wiper arm. Therefore, the amount of ice and snow adhering to the glass can be predicted with higher accuracy by considering the resistance that the wiper receives when the wiper is operated than when predicted from the external environment around the vehicle position. It should be noted that the relationship between the amount of ice and snow adhering to the glass and the resistance that the wiper receives when the wiper is activated may be derived in advance by experiments or simulations and stored as a map in a memory accessible by the control ECU 10 or an actual wiper. 42 may be adapted by learning during operation. Further, the resistance received by the wiper during the operation of the wiper may be detected using, for example, a torque sensor as the output torque of the wiper motor, or estimated based on a current value / voltage value (motor current, etc.) applied to the wiper motor. May be.

  In step 250, the control ECU 10 determines the time when the ice / snow adhesion amount falls below a predetermined threshold based on the ice / snow adhesion amount on the glass predicted in step 240 and the future operation time or work amount of the glass heating device 40. Predicting and determining the time as the next operation time of the wiper 42 (next wiper operation timing). In this case, after the next operation, the processing after step 210 may be similarly executed.

  As described above, according to the present embodiment, the amount of ice and snow adhering on the glass is temporarily estimated based on the external environment around the vehicle position, the operation timing of the first wiper 42 is determined based on the estimation result, Based on the resistance received by the wiper 42 at that time, the first time the wiper 42 is operated at the operation timing, and the amount of ice / snow adhesion on the glass is secondarily estimated. The subsequent operation timing of the wiper 42 is determined. Therefore, according to this embodiment, even if the operation timing of the wiper 42 for the first time is inappropriate, even if the wiper arm does not move in the intended manner due to the operation, the resistance (operation) that the wiper 42 receives at that time The next operation timing of the wiper 42 can be appropriately determined based on the torque. As a result, it is possible to efficiently remove the ice and snow on the glass while preventing unnecessary power supply to the wiper 42 that is inoperable due to the ice and snow on the glass.

  In the present embodiment, the control ECU 10 may re-determine and update the operation mode of the glass heating device 40 based on the amount of ice / snow adhesion estimated based on the resistance received by the wiper 42. For example, when it is determined that melting of ice and snow on the glass by the glass heating device 40 does not proceed as scheduled based on the resistance received by the wiper 42, the output of the glass heating device 40 may be increased. Conversely, when it is determined in step 220 that the snow scraping by the wiper 42 is successful, the output of the subsequent glass heating device 40 may be reduced.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, when a boarding notification signal notifying the user's boarding is received, whether or not ice / snow removal by the operation of the wiper 42 or the like is performed based on the external environment around the vehicle position at that time is determined. Although it is determined (see step 110 in FIG. 2), the user can register the scheduled vehicle boarding time for the next day through an appropriate interface, for example, before reaching the destination and leaving the vehicle. In this case, the registration of the vehicle boarding scheduled time may be used as a signal for transmitting the user's boarding intention to the vehicle. In other words, in this case, execution of the same processing as when the above boarding notification signal is received may be started from a predetermined time before the registered vehicle boarding scheduled time. Such a configuration is advantageous in that the above effects can be easily obtained without using the remote operation device 80.

  In the above-described embodiment, the local receiver 70 periodically performs the current control progress state (that is, the user's scheduled boarding time or actual boarding detection time) with respect to the remote operation device 80 possessed by the user (ie, The progress of the ice / snow removing operation on the glass) or the scheduled time for completion of control may be notified. Thereby, the boarding timing to a vehicle can also be adjusted on the user side according to the present control progress state.

  From the same point of view, when the operation mode at the time of prior operation is limited due to the lack of capacity of the battery 60 as described above, the remote operation device 80 may be notified to that effect. As a result, the user who has received such a notification is expected to be in a state where the snow and ice removal state will not be sufficient at the time of boarding, so that the discomfort given to the user at the time of boarding can be reduced, and the system abnormality It is possible to prevent a feeling of fear.
