Patent number: 11306640Abstract: The electrically heated catalyst to which the present disclosure is applied is provided in a hybrid vehicle capable of switching its running mode between EV mode and HC mode and supplied with electrical energy before the internal combustion engine is started. An abnormality detection apparatus calculates an electrical energy parameter relating to the integrated value of electrical power actually supplied to the electrically heated catalyst (actually supplied electrical power) over a specific period of time from the time when supply of electrical power to the electrically heated catalyst is started and detects an abnormality of the electrically heated catalyst by comparing the electrical energy parameter with a threshold. The threshold is set according to the rate of decrease of the charge level of a battery (charge level decrease rate) during a period in which electrical power is supplied to the electrically heated catalyst.Type: GrantFiled: January 16, 2020Date of Patent: April 19, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shigemasa Hirooka, Tsuyoshi Obuchi, Shingo Korenaga

Patent number: 11306641Abstract: The controller adjusts a voltage applied to the electrically heated catalyst in such a way as to make the electrical power as the product of the applied voltage and the catalyst current equal to a target electrical power and to apply a voltage substantially equal to a specific upper limit voltage to the electrically heated catalyst when the electrical power that can be supplied to the electrically heated catalyst by applying a voltage equal to or lower than the specific upper limit voltage is lower than the target electrical power. The controller calculates an actually supplied electrical energy defined as the integrated value of the electrical power actually supplied to the electrically heated catalyst over a specific period. The controller determines that the electrically heated catalyst is abnormal if the actually supplied electrical energy is smaller than a specific electrical energy.Type: GrantFiled: January 16, 2020Date of Patent: April 19, 2022Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tsuyoshi Obuchi, Shigemasa Hirooka, Shingo Korenaga
