Abstract

Since display delays are caused by the delay in response of an LCD (20) under low temperature conditions, a microcomputer (16) determines whether or not temperature not higher than a preset temperature at which a liquid crystal response delay occurs has been detected by a vehicle interior temperature sensor (28). Upon occurrence of the delay in response of the LCD (20), the microcomputer (16) calculates the time taken to reach the temperature at which the response delay is eliminated on the basis of the detection result of a temperature sensor (22), and performs display control to display, on a display (14), the calculated time and the occurrence information showing the occurrence of the response delay.

Description

車両用表示装置Vehicle display device
　本発明は、車両に搭載されて車両周辺の撮影画像や各種情報等を表示する車両用表示装置に関する。 The present invention relates to a display device for a vehicle mounted on a vehicle and displaying a photographed image around the vehicle, various information, and the like.
　車両用表示装置として液晶を用いる場合には、氷点下等の低温時に液晶の応答性能が低下して映像の表示遅れが発生することがあるため、低温時の応答遅れに対処する必要がある。 When a liquid crystal is used as a display device for a vehicle, the response performance of the liquid crystal may decrease at low temperatures such as below the freezing point to cause a delay in displaying an image, so it is necessary to cope with the response delay at low temperatures.
　例えば、低温時の液晶の応答遅れに対応する技術として特開２０１０－１７５３６９号公報の技術が提案されている。 For example, as a technique for coping with the response delay of liquid crystal at low temperature, the technique of JP-A-2010-175369 has been proposed.
　特開２０１０－１７５３６９号公報の車両用表示装置では、車両の所定状態を表示する液晶表示パネルと、液晶表示パネルを透過照明する光源と、液晶表示パネル及び光源を制御する制御手段と、車両内に設けられ温度に応じた信号を制御手段へ出力する温度検出手段とを備えている。そして、制御手段が、車両利用者に警報を報知するための点滅表示を行う際に、温度検出手段からの信号に基づいて、所定温度以下であるか否かを判定し、所定温度以下である場合に光源を点滅制御することが提案されている。 In the vehicle display device disclosed in JP 2010-175369 A, a liquid crystal display panel for displaying a predetermined state of the vehicle, a light source for transmitting and illuminating the liquid crystal display panel, a control means for controlling the liquid crystal display panel and the light source, And temperature detection means for outputting a signal corresponding to the temperature to the control means. Then, when the control means performs flickering display to notify the vehicle user of an alarm, it determines whether or not the temperature is lower than or equal to the predetermined temperature based on the signal from the temperature detection means. It has been proposed to control the light source to blink in the case.
　しかしながら、特開２０１０－１７５３６９号公報では、低温時の液晶の応答速度が低下するため、点滅して警告表示する際に、光源を点滅させて液晶の点滅の応答遅れを光源の点滅で補助しているが、警告以外の表示については低温時の対策がなされていないため、改善の余地がある。 However, in Japanese Patent Application Laid-Open No. 2010-175369, the response speed of the liquid crystal at low temperature decreases, so when flashing and displaying a warning, the light source is made to blink and the response delay of the liquid crystal blinking is assisted by the blinking of the light source. However, there is room for improvement in the display other than the warning because measures are not taken at low temperatures.
　本発明は、上記事実を考慮して成されたもので、液晶表示部の低温時の応答遅れに対して注意を促すことが可能な車両用表示装置を提供することを目的とする。 The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to provide a display device for a vehicle which can draw attention to a response delay at low temperature of a liquid crystal display unit.
　上記目的を達成するために本開示の第１の態様は、車両周辺画像を表示する液晶表示部の温度を検出する検出部と、前記液晶表示部の応答遅れが発生する場合に、前記検出部の検出結果に基づいて、前記応答遅れが解消される予め定めた温度に到達するまでの到達時間を算出し、算出した前記到達時間及び前記液晶表示部の応答遅れの発生を表す発生情報を表示するように、前記液晶表示部を制御する制御部と、を備えている。 In order to achieve the above object, according to a first aspect of the present disclosure, there is provided a detection unit that detects a temperature of a liquid crystal display unit that displays an image around a vehicle and the detection unit when response delay of the liquid crystal display unit occurs. The arrival time until reaching a predetermined temperature at which the response delay is eliminated is calculated based on the detection result of the above, and the generated arrival time representing the calculated arrival time and the response delay of the liquid crystal display unit is displayed And a control unit that controls the liquid crystal display unit.
　本開示の第１の態様によれば、検出部では、車両周辺画像を表示する液晶表示部の温度が検出される。 According to the first aspect of the present disclosure, the detection unit detects the temperature of the liquid crystal display unit that displays the vehicle peripheral image.
　そして、制御部では、液晶表示部の応答遅れが発生する場合に、検出部の検出結果に基づいて、液晶表示部の応答遅れが解消される予め定めた温度に到達するまでの到達時間を算出し、算出した到達時間及び液晶表示部の応答遅れの発生を表す発生情報を表示するように、液晶表示部が制御される。 Then, when the response delay of the liquid crystal display unit occurs, the control unit calculates the arrival time until reaching a predetermined temperature at which the response delay of the liquid crystal display unit is eliminated based on the detection result of the detection unit. The liquid crystal display unit is controlled so as to display the calculated arrival time and generation information indicating occurrence of response delay of the liquid crystal display unit.
　液晶表示部に、液晶表示装置の応答遅れが発生していることを表す発生情報が表示されると共に、応答遅れが解消されるまでの到達時間が表示されるので、液晶表示部の低温時の応答遅れに対して注意を促すことができる。また、到達時間が表示されるので、応答遅れ解消までの時間を乗員が認識することができる。 The liquid crystal display unit displays generated information indicating that the response delay of the liquid crystal display device is occurring, and the arrival time until the response delay is eliminated is displayed. Attention can be drawn to response delay. Further, since the arrival time is displayed, the occupant can recognize the time until the response delay is eliminated.
　なお、応答遅れが発生する場合は、本開示の第２の態様のように、車室内温度を検出する車室内温度検出部によって予め定めた温度以下の温度が検出された場合としてもよい。 When a response delay occurs, as in the second aspect of the present disclosure, a temperature lower than a predetermined temperature may be detected by a vehicle interior temperature detection unit that detects a vehicle interior temperature.
　また、制御部は、本開示の第３の態様のように、車室内温度検出部によって予め定めた温度以下の温度が検出された場合に、車両の予め定めた走行操作系の操作を禁止する制御を更に行ってもよい。これにより、液晶の応答遅れによる表示遅れが発生している場合に、運転を禁止することができ、安全性を確保することができる。 Further, as in the third aspect of the present disclosure, the control unit prohibits the operation of the predetermined travel operation system of the vehicle when a temperature equal to or lower than a predetermined temperature is detected by the vehicle interior temperature detection unit. Control may be further performed. As a result, when display delay occurs due to response delay of liquid crystal, driving can be prohibited, and safety can be ensured.
　さらに、制御部は、本開示の第４の態様のように、到達時間及び発生情報を表示する際に、車両周辺画像を非表示にするか、または車両周辺画像に重ねて到達時間及び発生情報を液晶表示部の全面に亘って表示するように、前記液晶表示部を制御してもよい。すなわち、車両周辺画像の表示自体を見難くまたは非表示とすることで、表示遅れが発生している場合に、乗員に運転を控えさせることができる。 Furthermore, when displaying the arrival time and the generation information as in the fourth aspect of the present disclosure, the control unit hides the vehicle periphery image or superimposes the arrival time and the generation information on the vehicle periphery image. The liquid crystal display unit may be controlled to display the entire screen of the liquid crystal display unit. That is, by making it hard to see or hide the display of the vehicle periphery image, it is possible to make the passenger refrain from driving when a display delay occurs.
　以上説明したように本発明によれば、液晶表示部の低温時の応答遅れに対して注意を促すことが可能な車両用表示装置を提供することができる、という効果がある。 As described above, according to the present invention, it is possible to provide a display device for a vehicle that can draw attention to a response delay at low temperature of the liquid crystal display unit.

　本実施形態では、ディスプレイ１４は、車両の後側方や後方をカメラで撮影した撮影画像をＬＣＤ２０に表示し、アウターミラーやインナーミラーの代わりとして機能する。 In the present embodiment, the display 14 displays on the LCD 20 a photographed image obtained by photographing the rear side and the rear of the vehicle with a camera, and functions as a substitute for the outer mirror and the inner mirror.
　映像受信部１９は、制御装置１２から送信される画像情報を受信してシリアルデータからパラレルデータに変換してＬＣＤ２０に出力することにより、ＬＣＤ２０に画像を表示する。 The video reception unit 19 receives the image information transmitted from the control device 12, converts the serial data into parallel data, and outputs the parallel data to the LCD 20, thereby displaying the image on the LCD 20.
　温度センサ２２は、ＬＣＤ２０の温度またはＬＣＤ２０の周辺の温度を検出し、検出した温度を示す情報を制御装置１２に出力する。 The temperature sensor 22 detects the temperature of the LCD 20 or the temperature around the LCD 20 and outputs information indicating the detected temperature to the control device 12.
　ディスプレイ１４及び制御装置１２は、接地端子を有しており、それぞれが接続されて自動車のボディーアース等に接地されている。 The display 14 and the control device 12 have ground terminals, which are connected to each other and are grounded to the body ground of the automobile or the like.
　制御装置１２は、ディスプレイ１４を制御するためのマイコン１６が設けられていると共に、ＬＣＤ２０に表示する映像を送信するための映像送信部１８が設けられており、マイコン１６に映像送信部１８が接続されている。 The control device 12 is provided with a microcomputer 16 for controlling the display 14 and a video transmission unit 18 for transmitting a video to be displayed on the LCD 20. The video transmission unit 18 is connected to the microcomputer 16 It is done.
　映像送信部１８は、ＬＣＤ２０に表示するための画像を表す画像情報をパラレルデータからシリアルデータに変換してディスプレイ１４に送信する。 The video transmission unit 18 converts image information representing an image to be displayed on the LCD 20 from parallel data into serial data, and transmits the converted data to the display 14.
　また、マイコン１６には、ディスプレイ１４に設けられた温度センサ２２が接続されている。 Further, a temperature sensor 22 provided on the display 14 is connected to the microcomputer 16.
　温度センサ２２は、プルアップ抵抗Ｒを介してバッテリＢＴが接続されており、温度センサ２２の検出結果がマイコン１６に入力される。 The battery BT is connected to the temperature sensor 22 via the pull-up resistor R, and the detection result of the temperature sensor 22 is input to the microcomputer 16.
　また、マイコン１６には、車両に設けられた他ＥＣＵ２４が接続されており、各種情報が他ＥＣＵ２４を介して取得可能とされている。本実施形態では、他ＥＣＵ２４に接続された車室内温度センサ２６、及びドアロックスイッチ２８の各情報が他ＥＣＵ２４を介してマイコン１６に入力されるようになっている。 Further, the other ECU 24 provided in the vehicle is connected to the microcomputer 16 so that various information can be acquired via the other ECU 24. In the present embodiment, each information of the vehicle interior temperature sensor 26 and the door lock switch 28 connected to the other ECU 24 is input to the microcomputer 16 through the other ECU 24.
　車室内温度センサ２８は、車室内の温度を検出し、ドアロックスイッチ３２は、ドアロックの解錠及び施錠を検出する。なお、車室内温度センサ２８は、他ＥＣＵ２４が検出結果を用いた制御を行うために車室内温度を常時検出するものが好ましい。 A passenger compartment temperature sensor 28 detects the temperature in the passenger compartment, and a door lock switch 32 detects unlocking and locking of the door lock. It is preferable that the vehicle interior temperature sensor 28 constantly detect the temperature in the vehicle interior so that the other ECU 24 performs control using the detection result.
　ところで、氷点下などの低温時には液晶の応答速度が低下するため、ＬＣＤ２０の応答遅れによる表示遅れが発生する。そこで、本実施形態では、マイコン１６が、車室内温度センサ２８によって液晶の応答遅れが発生する予め定めた温度以下の温度が検出されたか否かを判定する。また、ＬＣＤ２０の応答遅れが発生する場合に、マイコン１６が、温度センサ２２の検出結果に基づいて応答遅れが解消される温度に到達するまでの到達時間を算出し、算出した到達時間及び応答遅れが発生していることを表す発生情報をディスプレイ１４に表示する表示制御を行う。 By the way, since the response speed of the liquid crystal decreases at low temperatures such as below the freezing point, a display delay due to the response delay of the LCD 20 occurs. Therefore, in the present embodiment, the microcomputer 16 determines whether or not a temperature lower than a predetermined temperature at which a response delay of liquid crystal occurs is detected by the vehicle interior temperature sensor 28. Further, when the response delay of the LCD 20 occurs, the microcomputer 16 calculates the arrival time until reaching the temperature at which the response delay is eliminated based on the detection result of the temperature sensor 22, and the calculated arrival time and response delay Control is performed to display on the display 14 occurrence information representing that the event is occurring.
　なお、応答遅れが解消される温度に到達するまでの到達時間は、到達時間＝｛定数×（目標温度－現在温度）｝÷（電圧×電流）により算出する。ここで、定数は、液晶ディスプレイ個別に設定される値であり、メモリに予め保存される。また、目標温度は、応答遅れが解消される予め定めた温度でメモリに予め保存される。 The arrival time until the temperature at which the response delay is eliminated is reached is calculated by: arrival time = {constant × (target temperature−current temperature)} ÷ (voltage × current). Here, the constant is a value set individually for the liquid crystal display, and is stored in advance in the memory. Further, the target temperature is stored in advance in the memory at a predetermined temperature at which the response delay is eliminated.
　また、到達時間は、例えば、ドアロックの解除された場合に、多重通信によって車室内温度センサ２８の検出結果をマイコン１６が取得してドアロックの解除をトリガとして算出する。また、ＬＣＤの温度は、本実施形態では、ＬＣＤ２０への通電による自己発熱により上昇するものとして説明するが、エアコンやヒータなどによって上昇するようにしてもよい。 Further, when the door lock is released, for example, when the door lock is released, the microcomputer 16 acquires the detection result of the vehicle interior temperature sensor 28 by multiplex communication and calculates the release of the door lock as a trigger. Further, in the present embodiment, the temperature of the LCD is described as rising due to self-heating due to energization of the LCD 20, but may be raised by an air conditioner, a heater or the like.
　続いて、上述のように構成された本実施形態に係る車両用表示装置１０のマイコン１６で行われる具体的な処理について説明する。図２は、本実施形態に係る車両用表示装置１０のマイコン１６で行われる処理の流れの一例を示すフローチャートである。なお、図２の処理は、本実施形態では、ドアロックスイッチ３２によってドアロックの解錠が検出されて検出信号がマイコン１６に入力された場合に開始する。また、図２の処理は、例えば、マイコン１６に予め記憶されたプログラムを実行することにより行われる。 Then, the specific process performed with the microcomputer 16 of the display apparatus 10 for vehicles which concerns on this embodiment comprised as mentioned above is demonstrated. FIG. 2 is a flowchart showing an example of the flow of processing performed by the microcomputer 16 of the vehicle display device 10 according to the present embodiment. In the present embodiment, the process of FIG. 2 starts when the door lock switch 32 detects unlocking of the door lock and the detection signal is input to the microcomputer 16. Further, the process of FIG. 2 is performed, for example, by executing a program stored in advance in the microcomputer 16.
　ドアロックスイッチ３２によってドアロックの解錠が検出されると、ステップ１００では、マイコン１６が、他ＥＣＵ２４を介して車室内温度センサ２８によって検出された車室内温度情報を取得してステップ１０２へ移行する。 When unlocking of the door lock is detected by the door lock switch 32, in step 100, the microcomputer 16 acquires in-room temperature information detected by the in-room temperature sensor 28 via the other ECU 24 and proceeds to step 102. Do.
　ステップ１０２では、マイコン１６が、車室内温度が０℃以下であるか否かを判定する。本実施形態では、車室内温度が０℃以下であるか否かを判定することにより、ＬＣＤ２０の応答遅れによる表示遅れが発生するか否かを判定し、該判定が肯定された場合にはステップ１０４へ移行し、否定された場合にはステップ１１２へ移行する。 In step 102, the microcomputer 16 determines whether the temperature in the passenger compartment is 0 ° C. or less. In the present embodiment, it is determined whether the display delay due to the response delay of the LCD 20 occurs or not by determining whether the temperature in the vehicle compartment is 0 ° C. or less, and if the determination is affirmed, the step Control is passed to step 104, and if denied, control is passed to step 112.
　ステップ１０４では、マイコン１６が、温度センサ２２によって検出されたＬＣＤ２０の温度情報を取得してステップ１０６へ移行する。 At step 104, the microcomputer 16 acquires the temperature information of the LCD 20 detected by the temperature sensor 22 and shifts to step 106.
　ステップ１０６では、マイコン１６が、現在のＬＣＤ２０の駆動電流及び駆動電圧と、取得したＬＣＤ２０の温度情報と、を用いて、上述の到達時間＝｛定数×（目標温度－現在温度）｝÷（電圧×電流）の式から、到達時間を算出してステップ１０８へ移行する。 In step 106, the microcomputer 16 uses the current driving current and driving voltage of the LCD 20, and the acquired temperature information of the LCD 20 to obtain the above-mentioned arrival time = {constant × (target temperature-current temperature)} ÷ (voltage From the equation of × current, the arrival time is calculated, and the process proceeds to step 108.
　ステップ１０８では、マイコン１６が、算出した到達時間、及び発生情報としてのメッセージをＬＣＤ２０に表示するように制御してステップ１１０へ移行する。例えば、図３Ａに示すように、「表示遅れ発生中、表示遅れ解消まであと○○秒」等のように表示することにより、低温による表示遅れが発生していることを乗員に報知する。これにより、ＬＣＤ２０の表示が遅れて正常ではないことを乗員が認識することができる。なお、この時、ＬＣＤ２０に表示する車両周辺の撮影画像は、図３Ａに示すように、車両周辺の撮影画像に重ねてメッセージ等を全面に亘って大きく表示して車両周辺の撮影画像が見難いようにしてもよい。或いは、図３Ｂに示すように、車両周辺の撮影画像は非表示としてメッセージのみを表示してもよい。すなわち、インナーミラーやアウターミラーとして機能させるため、正常な表示ができない場合には、表示自体を見難くまたは非表示とすることで、運転を控えさせることができる。 In step 108, the microcomputer 16 controls the LCD 20 to display the calculated arrival time and a message as generation information, and the process proceeds to step 110. For example, as shown in FIG. 3A, the occupant is notified that the display delay due to the low temperature is occurring, by displaying as “during display delay, 解 消 seconds until display delay is eliminated” or the like. Thus, the occupant can recognize that the display on the LCD 20 is delayed and not normal. At this time, as shown in FIG. 3A, the photographed image of the vehicle periphery displayed on the LCD 20 is superimposed on the photographed image of the vehicle periphery and a message etc. is largely displayed over the entire surface and the photographed image of the vehicle periphery is hard to see You may do so. Or as shown to FIG. 3B, you may display only a message by making the picked-up image around a vehicle into non-display. That is, in order to function as an inner mirror or an outer mirror, when normal display can not be performed, it is possible to refrain from driving by making the display itself difficult to see or not to display.
　ステップ１１０では、マイコン１６が、到達時間経過したか否かを判定し、該判定が否定された場合にはステップ１０４に戻って上述の処理を繰り返し、判定が肯定された場合にステップ１１２へ移行する。 In step 110, the microcomputer 16 determines whether or not the arrival time has elapsed. If the determination is negative, the process returns to step 104 to repeat the above-described processing, and if the determination is affirmed, the process proceeds to step 112. Do.
　ステップ１１２では、マイコン１６が、通常表示へ移行するようにＬＣＤ２０を制御する。これにより、到達時間及びメッセージの表示を停止して、車両周辺の撮影画像を表示する。 At step 112, the microcomputer 16 controls the LCD 20 to shift to the normal display. Thereby, the display of the arrival time and the message is stopped, and the photographed image around the vehicle is displayed.
　このように、マイコン１６が処理を行うことで、低温時に発生するＬＣＤ２０の応答遅れによる表示遅れを乗員に報知して、低温時のＬＣＤ２０の応答遅れに対して注意を促すことができる。また、表示遅れが解消されるまでの到達時間が表示されるので、表示遅れ解消までの時間を乗員が認識することができる。 As described above, since the microcomputer 16 performs the processing, the display delay due to the response delay of the LCD 20 occurring at the low temperature can be notified to the occupant, and the response delay of the LCD 20 at the low temperature can be alerted. Further, since the arrival time until the display delay is eliminated is displayed, the occupant can recognize the time until the display delay is eliminated.
　次に、本実施形態に係る車両用表示装置１０のマイコン１６で行われる処理の変形例について説明する。基本的な構成は、上記の実施形態と同一であるため、構成の説明を省略する。図４は、本実施形態に係る車両用表示装置１０のマイコン１６で行われる処理の変形例を示すフローチャートである。なお、図２の処理と同一処理については、同一符号を付して詳細な説明を省略する。 Next, a modification of the process performed by the microcomputer 16 of the vehicle display device 10 according to the present embodiment will be described. The basic configuration is the same as that of the above embodiment, and thus the description of the configuration is omitted. FIG. 4 is a flow chart showing a modification of the process performed by the microcomputer 16 of the display device 10 for a vehicle according to the present embodiment. The same processes as those in FIG. 2 are assigned the same reference numerals and detailed explanations thereof will be omitted.
　上記の実施形態では、ＬＣＤ２０の表示遅れが発生した場合に、表示遅れが解消するまでの到達時間及びメッセージを表示し、車両周辺の撮影画像が見難い又は非表示とする例を説明したが、変形例では表示以外に走行操作系の操作を更に禁止するようにしている。 In the above embodiment, when the display delay of the LCD 20 occurs, an example is shown in which the arrival time until the display delay disappears and a message are displayed, and the captured image around the vehicle is difficult to see or not displayed. In the modification, the operation of the traveling operation system is further prohibited in addition to the display.
　具体的には、変形例では、図４に示すように、図２のステップ１０８とステップ１１０の間にステップ１０９を追加すると共に、ステップ１１０とステップ１１２の間にステップ１１１を追加した処理を行う。 Specifically, in the modification, as shown in FIG. 4, step 109 is added between step 108 and step 110 in FIG. 2, and step 111 is added between step 110 and step 112. .
　すなわち、ステップ１０８において、到達時間及びメッセージをＬＣＤ２０に表示した後にステップ１０９へ移行して、マイコン１６が走行操作系の操作禁止信号を他ＥＣＵ２４に出力してステップ１１０へ移行する。これにより、例えば、シフト操作やアクセル操作等の走行操作系の操作を禁止することにより、ＬＣＤ２０の表示遅れが発生している間の運転を禁止することができる。 That is, after the arrival time and the message are displayed on the LCD 20 in step 108, the process proceeds to step 109, the microcomputer 16 outputs an operation prohibition signal of the traveling operation system to the other ECU 24 and proceeds to step 110. Thus, for example, by prohibiting the operation of the traveling operation system such as the shift operation or the accelerator operation, it is possible to inhibit the operation while the display delay of the LCD 20 is occurring.
　一方、ステップ１１０において、到達時間経過した場合にはステップ１１１へ移行して、マイコン１６が、走行操作系の操作許可信号を他ＥＣＵ２４に出力してステップ１１２へ移行する。これにより、禁止した走行操作系の操作を許可する。すなわち、到達時間が経過して通常の表示に移行した場合に、走行操作系の操作を許可して運転を許可する。 On the other hand, when the arrival time has elapsed in step 110, the process proceeds to step 111, the microcomputer 16 outputs an operation permission signal of the traveling operation system to the other ECU 24, and proceeds to step 112. This permits the prohibited operation of the traveling operation system. That is, when reaching time passes and it transfers to a normal display, operation of a traveling operation system is permitted and driving is permitted.
　このようにマイコン１６が処理を行うことで、上記の実施形態と同様の効果を得ると共に、車両周辺の撮影画像の表示が遅れて表示されている間の運転を禁止して、安全を向上することができる。 Thus, the microcomputer 16 performs the processing to obtain the same effect as that of the above-described embodiment, and to inhibit the driving while the display of the photographed image around the vehicle is delayed and to improve the safety. be able to.
　なお、上記の実施形態では、ステップ１００、１０２において、他ＥＣＵ２４から取得した車室内温度センサ２８の検出結果からＬＣＤ２０の応答速度が低下する温度として車室内温度が０℃以下か否かを判定するようにしたが、これに限るものではない。例えば、温度センサ２２の検出結果からＬＣＤ２０の応答速度が低下する温度であるか否かを判定してもよい。或いは、温度センサ２２及び車室内温度センサ２８の検出結果をそれぞれ取得して、それぞれの温度が予め定めた温度以下であるか否か判定してもよい。或いは、外気温を検出する外気温センサの検出結果を他ＥＣＵ２４を介して取得して、外気温センサによって検出された結果が予め定めた温度以下であるか否かを判定してもよい。或いは、外気温の他に上記の各センサの検出結果もそれぞれ取得してそれぞれの温度が予め定めた温度以下であるか否かを判定してもよい。 In the above embodiment, in steps 100 and 102, it is determined from the detection result of the vehicle interior temperature sensor 28 acquired from the other ECU 24 whether the interior temperature of the vehicle interior is 0 ° C. or lower as the temperature at which the response speed of the LCD 20 decreases. Although it did, it does not restrict to this. For example, it may be determined from the detection result of the temperature sensor 22 whether it is a temperature at which the response speed of the LCD 20 decreases. Alternatively, the detection results of the temperature sensor 22 and the vehicle interior temperature sensor 28 may be acquired to determine whether or not the respective temperatures are equal to or lower than a predetermined temperature. Alternatively, the detection result of the outside air temperature sensor that detects the outside air temperature may be acquired via the other ECU 24 and it may be determined whether the result detected by the outside air temperature sensor is equal to or less than a predetermined temperature. Alternatively, in addition to the outside air temperature, the detection result of each of the above-described sensors may be obtained, and it may be determined whether or not each temperature is equal to or less than a predetermined temperature.
　また、上記の実施形態では、ディスプレイ１４は、車両の後側方や後方をカメラで撮影した撮影画像を表示してアウターミラーやインナーミラーの代わりとして機能する例を一例として説明したが、これに限るものではない。ディスプレイ１４は、車両周辺の撮影画像以外の車両の各種情報等を表示するものを適用してもよい。 In the above embodiment, the display 14 displays a photographed image obtained by photographing the rear side and the rear of the vehicle with a camera as an example of functioning as a substitute for the outer mirror and the inner mirror. It is not limited. The display 14 may be adapted to display various information of the vehicle other than the photographed image around the vehicle.
　また、上記の実施形態及び変形例では、ステップ１１０において、到達時間が経過したか否かを判定し、到達時間を経過した場合に通常表示に移行するようにしたが、ステップ１１０の判定はこれに限るものではない。例えば、ステップ１１０の判定は、温度センサ２２によって応答遅れが解消される温度が検出されたか否かを判定してもよい。或いは、到達時間経過後に応答遅れが解消される温度が検出されたか否かを判定してもよい。 Moreover, in said embodiment and modification, in step 110, it was determined whether arrival time passed, and when arrival time passed, it was made to transfer to a normal display, but the determination of step 110 is this It is not limited to For example, in the determination of step 110, it may be determined whether or not the temperature at which the response delay is eliminated is detected by the temperature sensor 22. Alternatively, it may be determined whether or not the temperature at which the response delay is eliminated after the arrival time has been detected.
　また、上記の実施形態におけるマイコン１６で行われる処理は、ソフトウエアの処理として説明したが、これに限るものではない。例えば、ハードウエアで行う処理としてもよいし、ハードウエアとソフトウエアの双方を組み合わせた処理としてもよい。 Moreover, although the process performed with the microcomputer 16 in said embodiment was demonstrated as a process of software, it is not restricted to this. For example, processing may be performed by hardware, or processing combining both hardware and software may be used.
　また、上記の実施形態におけるマイコン１６で行われる処理は、プログラムとして記憶媒体に記憶して流通させるようにしてもよい。 Further, the processing performed by the microcomputer 16 in the above embodiment may be stored as a program in a storage medium and distributed.
　さらに、本発明は、上記に限定されるものでなく、上記以外にも、その主旨を逸脱しない範囲内において種々変形して実施可能であることは勿論である。 Furthermore, the present invention is not limited to the above, and it goes without saying that various modifications can be made without departing from the scope of the invention.
