じる。 In the above-mentioned continuously variable transmission, during braking deceleration while driving at a high gear ratio, the opening of the throttle valve is at its minimum, so the engine speed becomes considerably low and the signal from the engine speed sensor 12 changes to the gear ratio. After the force urging the control valve 8 in the opening direction becomes sufficiently small, the gear ratio control valve 8 closes the supply fluid passage 14.
is operated to close the drain passage 14' and open the drain passage 14', resulting in a switch to the low ratio side, resulting in a characteristic as shown in c in Figure 3. Therefore, the engine brake does not work effectively, making safe driving impossible. Not only is this undesirable in terms of safety, but it also increases the load on the brakes and causes problems such as increased wear and tear on brake components.
