Title: (EN) ELECTRIC VEHICLE
(JA) 電動車両、及び電動車両のための制御ユニット
Abstract: front page image
(EN) PROBLEM TO BE SOLVED: To provide a control technique which can properly protect the circuit parts of an inverter, etc. even when continuing the running, with one motor in a non-driving state, in an electric vehicle where the same shaft is driven by two or more motors.

SOLUTION: This is an electric vehicle which is equipped with a drive shaft that outputs driving force and at least two motors that output motive power to the drive shaft. It is equipped with a control means which executes torque limitation for a motor in a driving state, based on the counterelectromotive force of the above motor in a non-driving state, when some motor is in the non-driving state.

【課題】2つ以上の電動機によって同一軸を駆動する電動車両において、一方の電動機を非駆動状態にして走行を継続する場合でもインバータ等の回路部品を適切に保護することができる制御技術を提供する。
【解決手段】駆動力を出力する駆動軸と、該駆動軸に動力を出力する少なくとも2つの電動機とを備えた電動車両であって、いずれかの電動機が非駆動状態にある場合に、駆動状態にある電動機に対して前記非駆動状態の電動機の逆起電力に基づきトルク制限を実行する制御手段を備える。
