Latest Patents
Yamada's latest patents include a diagnosis device for vehicles and a system for controlling an exhaust gas sensor with a heater. The diagnosis device is designed to assess the functionality of a starter after an engine has automatically stopped. It initiates a diagnosis when the engine speed drops to a specific threshold, allowing for the detection of starter malfunctions before the engine is halted. This innovation helps prevent situations where the engine cannot be restarted due to starter issues.
The second patent focuses on an exhaust gas sensor that detects oxygen concentration in exhaust gases. This sensor is equipped with a heater and is controlled by an electronic control unit. To prevent water condensation on the sensor, which can lead to cracking, the system adjusts the ignition timing of the engine to raise exhaust gas temperatures before activating the sensor. This approach minimizes the risk of damage while ensuring efficient sensor operation.
