Patent attributes
An in-vehicle controller prohibits engagement of a lock-up clutch when a temperature of a fluid that actuates the lock-up clutch is lower than a prescribed temperature. In addition, the in-vehicle controller stops fuel injection by a fuel injection valve when fuel cut conditions including such a condition that the lock-up clutch is engaged are established. Under a situation where the temperature of the fluid is lower than the prescribed temperature, in the case where a PM accumulation amount on a filter is equal to or larger than an accumulation amount threshold, the in-vehicle controller executes speed increase processing so as to execute gear shift control of a continuously variable transmission such that a rotational speed of a turbine impeller in a torque converter is increased to be higher than that in a case where the PM accumulation amount is smaller than the accumulation amount threshold.
