Patent number: 11964534Abstract: A control apparatus for a vehicle disclosed herein is applied to a vehicle configured to perform pre-air conditioning of the interior of the vehicle by starting an internal combustion engine according to a remote control signal sent from a remote controller. When starting pre-air conditioning according to the remote control signal, the control apparatus sets the control mode of the vehicle to a drive-disabling mode, which is a control mode that disables an operation for driving the vehicle. If a specific mode-cancelling operation is detected in a situation in which the remote controller is present in the interior of the vehicle while the control mode of the vehicle is being set to the drive-disabling mode, the control apparatus cancels the drive-disabling mode while leaving the internal combustion engine operating.Type: GrantFiled: May 14, 2021Date of Patent: April 23, 2024Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Tatsunori Katoh, Takaaki Inokuchi, Hiroyasu Hadano, Asuka Marumo

Patent number: 11821399Abstract: In a case where an engine is started based on a remote operation, a limitation condition for limiting an engine start is tightened or a stop condition after the engine is started is relaxed, as compared to a case where the engine is started based on a switch operation in an occupant cabin. That is, it is difficult to start the engine when the engine is started based on the remote operation, and it is easy to stop the engine when the engine is started based on the remote operation. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.Type: GrantFiled: April 21, 2022Date of Patent: November 21, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takaaki Inokuchi, Tatsunori Katoh, Tsutomu Miyazaki

Patent number: 7707822Abstract: An air-fuel ratio of each cylinder is estimated on the basis of a detection value of an air-fuel ratio sensor disposed in an exhaust confluent portion. An air-fuel ratio correction quantity is computed on the basis of the estimated air-fuel ratio of each cylinder. The air-fuel ratio of an air-fuel mixture to be supplied to each cylinder is corrected on the basis of the cylinder air-fuel ratio correction quantity to reduce a variation in the air-fuel ratio between the cylinders. When a state in which the cylinder air-fuel ratio correction quantity or its learning value of any cylinder is outside a specified range continues for a while during a period in which this cylinder air-fuel ratio control is performed, a combustion is stopped for the cylinder outside the specified range and the cylinder air-fuel ratio control is continuously performed only for other normal cylinders.Type: GrantFiled: June 28, 2007Date of Patent: May 4, 2010Assignee: DENSO CorporationInventors: Tatsunori Katoh, Yuuki Sakamoto
