Latest Patents

Keita Ejiri holds a patent for a "Vehicle gear-shifting control apparatus." This invention is designed to improve the efficiency of gear shifting in vehicles. The apparatus includes an engine, a motor, an automatic transmission, a friction brake system, and a controller. The controller executes regeneration control by imparting regenerative braking torque to the rear wheels. It also manages gear-shifting control by outputting a gear-shifting signal based on the rotation speed of the input shaft. The controller initiates gear-shifting control when the rotation speed decreases to a predetermined downshift point during a downshift. Additionally, during vehicle deceleration on low-friction surfaces, the controller adjusts the downshift point to enhance safety and performance.
