  • Patent number: 11028747
    Abstract: A controller for an internal combustion engine includes a fuel introduction process of introducing an air-fuel mixture containing fuel injected by a fuel injection valve into an exhaust passage without burning the air-fuel mixture in a cylinder. The fuel introduction processor is configured to perform, during the execution of the fuel introduction process, a determination process of determining whether afterfire, in which the air-fuel mixture burns at an upstream side of a three-way catalyst device in the exhaust passage, has occurred and a stopping process of stopping the fuel introduction process when determining in the determination process that the afterfire has occurred.

  • Publication number: 20210166532
    Abstract: To prevent delay in tactile presentation timing due to the responsiveness of the tactile presentation device, and to improve the reproducibility of the tactile sense. A drive control device according to the present technology includes a drive control unit that causes a drive unit that drives a tactile presentation device by a drive signal based on a tactile signal to execute a pre-drive, which is to drive the tactile presentation device in advance with respect to a rise timing of the tactile signal. By the pre-drive described above, a timing at which a tactile presentation is actually started can be brought close to a rise timing of a tactile signal.
