1. A controller for a vehicle, the controller comprising control circuitry, and the vehicle for which the controller is employed being equipped with an internal combustion engine, wherein the control circuitry is configured to execute:
an air supplying process that supplies air to a filter in an exhaust passage by driving an air pump of an air supply device, the internal combustion engine including the air supply device, the air supply device including the air pump and an air supply passage connected to a portion upstream of the filter in the exhaust passage, and the air supplying process drawing air into the exhaust passage through the air supply passage by driving the air pump so that the air drawn into the exhaust passage is supplied to the filter;
an oxygen supplying process that supplies oxygen to the filter through the exhaust passage, the oxygen having been passed through a combustion chamber of the internal combustion engine; and
a reducing process related to an air supply amount obtained through the air supplying process, the reducing process setting the air supply amount per unit time in the air supplying process obtained when the oxygen supplying process and the air supplying process are simultaneously executed to be lower than the air supply amount per unit time in the air supplying process obtained when the oxygen supplying process and the air supplying process are not simultaneously executed,
wherein when the oxygen supplying process is started during execution of the air supplying process, the air supply amount supplied by the air supplying process is reduced, and a time of the air supplying process is prolonged.
