Latest Patents

Ohi’s patent, “In-vehicle program update apparatus,” describes a gateway electronic control unit (ECU) that receives software update files wirelessly from an external center. An update condition table helps the gateway determine whether the vehicle is lightly or heavily loaded. When conditions permit, the gateway updates an ECU program. If the vehicle is heavily loaded, it can use environment-improvement control to shift the vehicle to a state suitable for updating.

His patent, “Gateway and in-vehicle network system,” concerns communication across multiple vehicle networks. When a gateway receives a request message, it relays the request to its destination and sends a wait request code to the source apparatus. This code extends the source’s specified timeout, allowing more time for a response.
