<p><P>PROBLEM TO BE SOLVED: To improve the durability of an automatic transmission by controlling an excessive inertia torque working on the automatic transmission on sudden braking. <P>SOLUTION: If a driver operates a brake pedal (YES at S106) while an actual vehicle speed is lower than a threshold value (YES at S100) and driving wheels are idling on a low-μroad (YES at S102, S104), an ECU controlling a belt-type continuously variable transmission executes upshift control for decreasing a transmission ratio by a predetermined value (S108), and also executes clamping-force increasing control for increasing a belt clamping pressure by a predetermined value (S110). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
