Abstract

DISPOSITIVO DE CONTROLE DE SENSOR DE OXIGêNIO PARA VEìCULO AUTOMOTIVO, E CONTROLADOR DE RAZãO AR - COMBUSTìVEL E VEìCULO AUTOMOTIVO QUE INCORPORA OS MESMOS. é descrito um dispositivo de controle que é arranjado para controlar um sensor de oxigênio para um veículo automotivo, em que o sensor de oxigênio tem um elemento sensor e um aquecedor para elevar uma temperatura do elemento sensor. O dispositivo de controle inclui uma seção de detecção de inclinação arranjada para detectar inclinação do corpo de um veículo; uma seção de armazenamento arranjada para armazenar informação de inclinação de acordo com um resultado da detecção pela seção de detecção de inclinação; e uma seção de controle arranjada para controlar, na partida de um motor do veículo, o aquecedor em um de uma pluralidade de modos, incluindo um modo normal e um modo com atraso no qual a elevação de temperatura do elemento sensor é atrasada em relação ao modo normal com base na informação de inclinação armazenada na seção de armazenamento.
