The invention provides a vehicle drive device. A vehicle drive device is provided with: a brake that selectively fixes a third rotating element to a fixing member and that has a plurality of friction plates, a first piston and a second piston that press the plurality of friction plates, and a first piston hydraulic chamber and a second piston hydraulic chamber that apply hydraulic pressure to each of the first piston and the second piston; a hydraulic pressure control circuit that controls the supply of hydraulic pressure to the first piston hydraulic chamber and the second piston hydraulic chamber; and a control device that, when the first travel mode is set, controls the hydraulic pressure control circuit so as to supply hydraulic pressure to the first piston hydraulic chamber and the second piston hydraulic chamber, and that, when the second travel mode is set, controls the hydraulic pressure control circuit so as to supply hydraulic pressure to the second piston hydraulic chamber. The hydraulic pressure control circuit is controlled so as to supply hydraulic pressure to only one of the first piston hydraulic chamber and the second piston hydraulic chamber.

    本发明提供车辆用驱动装置。车辆用驱动装置具备:制动器,具有多个摩擦板、按压多个摩擦板的第1活塞及第2活塞、以及用于使液压对第1活塞及第2活塞的各个活塞作用的第1活塞液压室及第2活塞液压室,该制动器将第3旋转元件选择性地固定到固定部件;控制向第1活塞液压室及第2活塞液压室的液压供给的液压控制回路;以及控制装置,控制装置在设定第1行驶模式时,以对第1活塞液压室以及第2活塞液压室供给液压的方式控制液压控制回路,在设定第2行驶模式时,以仅对第1活塞液压室以及第2活塞液压室的一方的活塞液压室供给液压的方式控制液压控制回路。
