Abstract
An in-vehicle controller includes processing circuitry. The processing circuitry stops injection of fuel under a preset fuel cutoff condition including a lockup clutch being in an engagement state. A request for raising heating performance of a heater core is a heater actuation request, and an amount of particulate matter deposited on a filter is a deposition amount. The processing circuitry controls the lockup clutch in a disengagement state when a heater actuation request is generated and the deposition amount is less than a preset deposition amount threshold. The processing circuitry controls the lockup clutch in the engagement state when the heater actuation request is generated and the deposition amount is greater than or equal to the preset deposition amount threshold.
