Heat collector for a hybrid vehicle is controlled so that during cold start-ups coolant recirculation to the combustion engine is prevented, as is automatic stopping of the combustion engine, resulting in improved starting

摘要

Heat collector for a hybrid vehicle that has an external combustion engine (12) and an electric motor (14). Control of coolant circulation between the combustion engine and the heat collector is such that at start-up from cold, the combustion engine is prevented from stopping automatically and pumping of hot coolant is prevented. This enables collection of hot coolant at start-up.
