Latest Patents

Among Junji Watanabe's latest inventions is a **Controller for Vehicle**, designed to enhance vehicle performance by integrating a chain tensioner that serves as an oil damper. This invention utilizes oil supplied from an oil pump and features a controller that can switch between battery electric vehicle (BEV) mode and non-BEV mode. An interesting aspect of this design is its capability to execute a high-pressure process to control oil pump supply; when the duration of BEV mode exceeds a specified time, the oil supply pressure to the chain tensioner is increased, optimizing vehicle performance during transitions.

Another notable patent is the **Vehicle Oil Supply Mechanism**. This invention includes an air introduction hole positioned strategically to maintain hydraulic pressure in the oil system. The design ensures that during travel, when the oil level in the pan changes, air is only introduced when it is safe to do so. This proactive design feature is particularly effective in heavy load scenarios, such as hill climbing, as it prevents air from being drawn into the oil strainer, thereby ensuring consistent high hydraulic pressure.
