また、制御装置６は、車室内の温度または外気温度が３０℃より高い場合は、空調装置５で消費する電力がモータ２で消費する電力よりも大きくなるようにする。 Further, the control device 6 makes the power consumed by the air conditioner 5 larger than the power consumed by the motor 2 when the temperature inside the vehicle compartment or the outside air temperature is higher than 30°C.
以上のように構成された本実施例に係る電動車両１による電力配分処理について、図４を参照して説明する。なお、以下に説明する電力配分処理は、制御装置６が動作を開始すると開始され、予め設定された時間間隔で実行される。 Electric power distribution processing by the electric vehicle 1 according to the present embodiment configured as described above will be described with reference to FIG. The power distribution process described below is started when the control device 6 starts operating and is executed at preset time intervals.
ステップＳ１において、制御装置６は、バッテリ温度センサ４１によりバッテリ４の温度を検出する。
In step S1, the control device 6 detects the temperature of the battery 4 with the
ステップＳ２において、制御装置６は、バッテリ温度が第１閾値よりも低いこと、または、バッテリ温度が第２閾値より高いことが成立しているか否かを判定する。バッテリ温度が第１閾値よりも低いこと、または、バッテリ温度が第２閾値より高いことが成立していないと判定した場合、制御装置６は、ステップＳ１に処理を戻して処理を繰り返す。 In step S2, the control device 6 determines whether the battery temperature is lower than the first threshold value or the battery temperature is higher than the second threshold value. When it is determined that the battery temperature is lower than the first threshold value or the battery temperature is higher than the second threshold value, the control device 6 returns the process to step S1 and repeats the process.
バッテリ温度が第１閾値よりも低いこと、または、バッテリ温度が第２閾値より高いことが成立していると判定した場合、ステップＳ３において、制御装置６は、バッテリ４のモードを出力制限モードに遷移させる。 When it is determined that the battery temperature is lower than the first threshold value or the battery temperature is higher than the second threshold value, the control device 6 sets the mode of the battery 4 to the output limit mode in step S3. Make a transition.
ステップＳ４において、制御装置６は、車室内温度または外気温度が第３閾値より低いか否かを判定する。車室内温度または外気温度が第３閾値より低いと判定した場合、ステップＳ５において、制御装置６は、モータ２で消費する電力と空調装置５で消費する電力の配分を前述の第１電力配分として、処理を終了する。 In step S4, the control device 6 determines whether the vehicle interior temperature or the outside air temperature is lower than the third threshold value. When it is determined that the vehicle compartment temperature or the outside air temperature is lower than the third threshold value, in step S5, the control device 6 sets the distribution of the power consumed by the motor 2 and the power consumed by the air conditioner 5 as the first power distribution described above. , The process ends.
ステップＳ４において車室内温度または外気温度が第３閾値より低くないと判定した場合、ステップＳ６において、制御装置６は、車室内温度または外気温度が第４閾値より高いか否かを判定する。車室内温度または外気温度が第４閾値より高いと判定した場合、ステップＳ７において、制御装置６は、モータ２で消費する電力と空調装置５で消費する電力の配分を前述の第２電力配分として、処理を終了する。 When determining in step S4 that the vehicle interior temperature or the outside air temperature is not lower than the third threshold value, the control device 6 determines in step S6 whether the vehicle interior temperature or the outside air temperature is higher than the fourth threshold value. When it is determined that the vehicle interior temperature or the outside air temperature is higher than the fourth threshold value, in step S7, the control device 6 sets the distribution of the power consumed by the motor 2 and the power consumed by the air conditioner 5 as the second power distribution described above. , The process ends.
ステップＳ６において車室内温度または外気温度が第４閾値より高くないと判定した場合、ステップＳ８において、制御装置６は、モータ２で消費する電力と空調装置５で消費する電力の配分を前述の第３電力配分として、処理を終了する。 When it is determined in step S6 that the vehicle interior temperature or the outside air temperature is not higher than the fourth threshold value, in step S8, the control device 6 allocates the power consumed by the motor 2 and the power consumed by the air conditioner 5 to the above-described first value. The process is terminated after 3 power distributions.
このように、本実施例では、バッテリ４のモードが出力制限モードの場合、車室内温度に応じて、モータ２で消費する電力と空調装置５で消費する電力を配分する。 As described above, in the present embodiment, when the battery 4 is in the output limiting mode, the power consumed by the motor 2 and the power consumed by the air conditioner 5 are distributed according to the vehicle interior temperature.
これにより、バッテリ４の出力が制限されている状態で、極寒や酷暑などの状況であっても、乗員の快適性を向上させることができる。 As a result, the comfort of the occupant can be improved even when the output of the battery 4 is limited and even in a situation such as extremely cold or severe heat.
また、車室内の温度が予め定められた適温よりも低い場合、または、車室内の温度が予め定められた適温よりも高い場合、空調装置５で消費する電力がモータ２で消費する電力よりも大きくなるように電力を配分する。 Further, when the temperature inside the vehicle compartment is lower than a predetermined appropriate temperature, or when the temperature inside the vehicle compartment is higher than the predetermined appropriate temperature, the power consumed by the air conditioner 5 is higher than the power consumed by the motor 2. Distribute electric power so that it becomes larger.
これにより、極寒や酷暑などの状況であっても、乗員の快適性を向上させることができる。 As a result, the comfort of the occupant can be improved even in a situation such as extremely cold or intense heat.
また、車室内の温度と外気温度の両方に応じて、モータ２で消費する電力と空調装置５で消費する電力を配分する。 In addition, the electric power consumed by the motor 2 and the electric power consumed by the air conditioner 5 are distributed according to both the temperature inside the vehicle compartment and the outside air temperature.
車室内の温度だけで判断する場合、車室内が適温になったときに電力配分が変わる。この結果、空調の効きが弱くなり、車外の状況によっては、すぐに不快な車室内環境に戻る可能性がある。車室内の温度と外気温度の両方に応じて、モータ２で消費する電力と空調装置５で消費する電力を配分するため、車室内が適温になった後、快適な車室内環境を維持することができる。 When judging only by the temperature inside the vehicle, the power distribution changes when the temperature inside the vehicle reaches an appropriate temperature. As a result, the effectiveness of the air conditioning is weakened, and depending on the conditions outside the vehicle, there is a possibility of immediately returning to an uncomfortable vehicle interior environment. Since the electric power consumed by the motor 2 and the electric power consumed by the air conditioner 5 are distributed according to both the temperature inside the vehicle interior and the outside air temperature, a comfortable vehicle interior environment is maintained after the vehicle interior has reached an appropriate temperature. You can
また、車室内の温度と外気温度の両方を閾値と比較し、この比較結果に応じて、モータ２で消費する電力と空調装置５で消費する電力を配分する。 Further, both the temperature inside the vehicle interior and the outside air temperature are compared with a threshold value, and the electric power consumed by the motor 2 and the electric power consumed by the air conditioner 5 are distributed according to the comparison result.

You can
本実施例では、車室内の温度や外気温度に応じて電力の配分を決定したが、乗員が決定できるようにしてもよい。例えば、多段階のうち一つを選択可能なスイッチを設け、段階ごとにモータ２で消費する電力と空調装置５で消費する電力の配分を決める。このようにすることで、乗員が任意で電力の配分を決定することができる。 In the present embodiment, the distribution of electric power is determined according to the temperature in the passenger compartment and the outside air temperature, but it may be determined by the occupant. For example, a switch that can select one of multiple stages is provided, and the distribution of the power consumed by the motor 2 and the power consumed by the air conditioner 5 is determined for each stage. By doing so, the occupant can arbitrarily decide the power distribution.
また、走行モードの切替時、例えば雪道モードやエコモードなどの駆動側の電力が少なくて済む走行モードの場合は、空調に配分する電力を多くするようにしてもよい。 In addition, when the driving mode is switched, for example, in the case of a driving mode such as a snow road mode or an eco mode that requires less power on the driving side, the power to be distributed to the air conditioning may be increased.
本実施例では、各種センサ情報に基づき制御装置６が各種の判定や算出を行なう例について説明したが、これに限らず、電動車両１が外部サーバ等の車外装置と通信可能な通信部を備え、該通信部から送信された各種センサの検出情報に基づき車外装置によって各種の判定や算出が行なわれ、その判定結果や算出結果を通信部で受信して、その受信した判定結果や算出結果を用いて各種制御を行なってもよい。 In the present embodiment, an example in which the control device 6 makes various determinations and calculations based on various sensor information has been described, but the present invention is not limited to this, and the electric vehicle 1 includes a communication unit capable of communicating with an external device such as an external server. , Various determinations and calculations are performed by the device outside the vehicle based on the detection information of the various sensors transmitted from the communication unit, the determination results and calculation results are received by the communication unit, and the received determination results and calculation results are displayed. You may perform various controls using it.
