With a total of five patents to his name, Sagami's work has had a considerable impact on vehicle performance and safety.
Latest Patents
One of Sagami's latest patents is an electric power steering device. This device provides appropriate power assist from the motor even when torque sensors fail and steering torque is no longer detected. If an error is detected in a torque sensor, the motor is driven based on the rotor rotation angle detected by a resolver and assist characteristics. When the absolute value of the rotor turning angle velocity falls to or below a prescribed value, a process is initiated to reduce the current driving the motor. If this state continues for a prescribed length of time, the process for reducing the current is interrupted, allowing for appropriate power assist during a steering retention period.
Another significant patent is the idle stop control device. This device is capable of relieving the reaction force (kickback) of a handle occurring during idle stop controlled by the idle stop control device. The EPSECU detects the rotational speed of an electric motor and the steering torque using a torque sensor. It determines whether the rotational speed and steering torque are within an idle stop transition area. If either is outside this area, a signal is sent to prohibit the transition to idle stop, ensuring safety and control.
