PROBLEM TO BE SOLVED: To achieve smooth operability free from a feeling of discomfort in an entire range, eliminating inconveniences such as a feeling of insufficient assist at the time of starting disengagement of a clutch, the slowness of a clutch at the time of starting a vehicle after waiting for a traffic light to change, which have occurred in a conventional electric clutch operation force assist device.SOLUTION: In a conventional control method in which pulling force of a clutch cable is detected by a load sensor, and when the output Vf of the load sensor increases (the pulling force increases), and exceeds a reference voltage (trigger threshold) Vr, an electric current is applied to a solenoid coil to assist the pulling force, detection of a position of a clutch lever is newly added, and the reference voltage (trigger threshold) Vr is changed according to the position Vs of the clutch lever so that optimum control can be executed in accordance with the situations at starting a vehicle, travelling in traffic congestion, stopping at a traffic signal, etc.SELECTED DRAWING: Figure 6
【課題】従来の電気式クラッチ操作力補助装置で発生する、クラッチ切りはじめのアシスト不足感や、信号待ち発進時のクラッチのもたつき感などの不具合をなくし、全域で違和感のない滑らかな操作性を実現する。【解決手段】クラッチケーブルの引き力を荷重センサーを使って検出し、この荷重センサーの出力Vfが増加し(引き力が増加し)、リファレンス電圧(トリガー閾値)Vrを超えたときにソレノイドコイルに電流を印加し引き力を助勢する従来の制御方法において、新たにクラッチレバーの位置検出を追加し、このクラッチレバーの位置Vsに応じてリファレンス電圧(トリガー閾値)Vrを変化させることで、車両の発進時、渋滞走行時、信号停止時などの状況に合った最適な制御を行なう。【選択図】図6
