Patent number: 11920508Abstract: An anomaly determination device, an anomaly determination method, and a memory medium for a water pump are provided. An acquisition process acquires an input variable of a map from image data obtained by capturing an outer surface of the water pump. Execution circuitry obtains provisional determination results from maps, respectively. The provisional determination results are respectively obtained by executing the provisional determination processes for output variables output from the maps. A determination finalizing process treats, as a majority of the provisional determination results, a final determination result indicating whether coolant has leaked out of the water pump.Type: GrantFiled: March 16, 2023Date of Patent: March 5, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomoyuki Kittaka, Tomoaki Suzuki, Makoto Ohno, Takuya Tsujiyama, Tadanobu Sobue, Raishiro Wada
