Latest Patents
One of Sato's latest patents is a control apparatus for hybrid electric vehicles. This apparatus includes an engine, a starter, and an electric motor connected to an electric storage device through a relay. The control apparatus executes an engine start control to crank and start the engine using either the starter or the electric motor. It also detects the presence or absence of failure in the electric motor during the engine start control process. If a failure is detected, the apparatus opens the relay and suspends the engine start control using the electric motor, ensuring that the starter is used for the next engine start request while keeping the relay open.
Another notable patent is related to motor-generated assist torque control for hybrid vehicles. This innovation involves a hybrid vehicle equipped with an acceleration pedal and an engine that generates torque based on the pedal's position. An electronic control unit calculates a target torque and estimates the motor-generated assist torque based on the difference between the target and engine torque. The motor generator then generates the estimated assist torque, which is delivered to the vehicle's wheels through a power distribution unit.
