To avoid a situation in which an engine brake does not work when a brake pedal is slightly pressed during travel and to make a vehicle less likely to slide downward when the brake pedal is released during stopping on a slope.SOLUTION: A switching position (switching timing) of a travel power selection switch 10 that switches between transmission/disconnection of travel power according to an amount that a brake pedal 12 is pressed is set at position B located before a position C at which a main brake starts to operate. Thereby, a range Y in which travel power is disconnected is made smaller than a conventional range (X+Y). As a result, disconnection of travel power when the brake pedal 12 is slightly pressed during travel is eliminated to avoid a situation in which an engine brake does not work. Travel power is enabled to be transmitted from the switching position B during release of the brake pedal 12 during stopping on a slope, making the vehicle less likely to slide downward.SELECTED DRAWING: Figure 5
【課題】走行中にブレーキペダルを僅かに踏んだときのエンジンブレーキが効かない状態を回避すると共に、傾斜地の停車中においてブレーキペダルを放していくときに車両をずれ落ちし難くする。【解決手段】ブレーキペダル12の踏み込み量に応じ、走行動力の伝達/遮断を切り換える走行動力切換スイッチ10の切り換え位置(切り換えタイミング)を、主ブレーキが効き始める位置Cの手前の位置Bに設定し、走行動力が遮断される範囲Yを従来の範囲(X+Y)より小さくする。その結果、走行中にブレーキペダル12を僅かに踏んだときの走行動力の遮断をなくしエンジンブレーキが効かない状態を回避すると共に、傾斜地の停車中においてブレーキペダル12を放していくときに途中の切り換え位置Bから走行動力の伝達を可能とし、車両をずれ落ちし難くする。【選択図】図5
