The **Hydraulic Pressure Supply Apparatus** is designed to quickly supply hydraulic pressure to a power transmission apparatus while extending the service life of an accumulator. This apparatus incorporates an oil pump powered by an internal combustion engine and is connected to the power transmission system via an oil passage. The setup allows for effective hydraulic pressure management, with a switching valve that opens during engine operation and closes during automatic stops. Additionally, manual stop-time control can activate the switching valve based on engine conditions, showcasing Uneyama's attention to operational efficiency.

The **Control Apparatus for an Automatic Transmission Mechanism** features a continuously variable transmission with a drive pulley, a driven pulley, and a belt connecting both. It intelligently adjusts control oil pressures based on the detected start of the vehicle's drive source. The system operates by initially setting a first command oil pressure to zero, while the second command oil pressure is increased, signaling when the filling of the cylinder chamber in the driven pulley is complete. This innovative control mechanism enhances transition smoothness and overall vehicle performance.
