Abstract
Official abstract text for this publication.
In a vehicle including an engine, an electrically heatable catalyst device (EHC), and a first motor generator that generates electric power in accordance with the engine's motive power with the vehicle in a substantially stopped state with a vehicular speed lower than a threshold vehicular speed, an ECU determines, based on an amount A by which an accelerator pedal is operated and a vehicular speed V, whether a large accelerator operation has been performed with the vehicle in the substantially stopped state. If the ECU determines that the large accelerator operation has been performed with the vehicle in the substantially stopped state, the ECU activates an energization timer, and before the energization timer reaches a reference energization period of time α, the ECU energizes the EHC, and once the energization timer has reached the reference energization period of time α, the ECU ceases energizing the EHC.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicular control device for a vehicle including an engine, an electrically heatable catalyst device purifying exhaust gas of said engine, and a first rotating electric machine, said first rotating electric machine generating electric power in accordance with motive power of said engine for a low speed state with a vehicular speed being a speed lower than a first vehicular speed, the vehicular control device comprising: a relay switching an electrica…
