To provide an exhaust cleaning controller of a hybrid vehicle for maintaining and managing the remaining capacity of a battery at a proper level and for heating an exhaust cleaning device by setting the output increase of an internal combustion engine as far as possible, and for suppressing costs by making it unnecessary to install a heating means whose power consumption is large, and for securing performance.
The hybrid vehicle is provided with an engine having an exhaust cleaning device, a motor generator, and a battery, and configured by including an electric heating means (EHC or the like) for heating each section of the engine including the exhaust cleaning device by consuming generation power of a motor generator or storage power of the battery; and a control means for, when it is decided that the operation of the engine is necessary on the basis of required driving force of the vehicle and the remaining capacity SOC of the battery, performing conduction control of the electric heating means before and after the start of the engine and control of driving and power generation of the engine and the motor generator on the basis of the required driving force of the vehicle and remaining capacity SOC and the temperature state (Tex or the like) of each section of the engine.
