PROBLEM TO BE SOLVED: To reduce the energy loss of an electric vehicle by performing appropriate travel support according to the state of a congestion sign.SOLUTION: An electric vehicle travel support device 10 comprises: a three-dimensional acceleration sensor 14; a congestion sign information calculation section 24; a determination section 25; an amount-of-charge calculation section 26; a charge planning section 27; and a travel control section 29. The congestion sign information calculation section 24 calculates a congestion sign indicator based on a change in acceleration acquired by the three-dimensional acceleration sensor 14. The determination section 25 determines whether the congestion sign indicator indicates the initial state of a congestion sign or indicates the immediately preceding state of congestion. The amount-of-charge calculation section 26 calculates chargeable amounts by a first power generation mode and a second power generation mode of an electric vehicle 1 in the initial state of the congestion sign and the immediately preceding state of the congestion. The charge planning section 27 plans charge schedules in the initial state of the congestion sign and the immediately preceding state of the congestion. The travel control section 29 gives instructions for the execution of the travel support of the electric vehicle 1 according to the charge schedules.SELECTED DRAWING: Figure 1
【課題】渋滞の予兆状態に応じて適切な走行支援を行うことによって電動車両のエネルギー損失を低減する。【解決手段】電動車両走行支援装置10は、3次元加速度センサ14、渋滞予兆情報算出部24、判定部25、充電量算出部26、充電計画部27、および走行制御部29を備える。渋滞予兆情報算出部24は、3次元加速度センサ14によって取得された加速度の変化に基づく渋滞予兆指標を算出する。判定部25は、渋滞予兆指標が、渋滞予兆の初期状態を示すか、渋滞の直前状態を示すかを判定する。充電量算出部26は、渋滞予兆の初期状態および渋滞の直前状態における電動車両1の第1発電モードおよび第2発電モードによる充電可能量を算出する。充電計画部27は、渋滞予兆の初期状態および渋滞の直前状態における充電スケジュールを計画する。走行制御部29は、充電スケジュールに応じて、電動車両1の走行支援の実行を指示する。【選択図】図1
