Automotive vehicle with automatic stop-restart system of internal combustion engine |
摘要 |
<p>An automotive vehicle with an automatic stop-restart system of an internal combustion engine, has a sensor sensing a rotational speed of the engine, and a motor generator coupled to an engine for rotation synchronously with the engine, and cranking the engine in response to a command needed to initiate a cranking cycle by a motoring operation of the motor generator, and subjected to a rotational speed feedback control after the rotational speed of the engine reaches a predetermined speed. The motor generator is capable of operating in a power-running mode to automatically restart the engine by the motoring torque and operating in a regenerative mode for energy regeneration. Also provided is a controller capable of executing an automatic engine-stop mode at which the engine is automatically stopped by fuel cutoff, and generating the command for an automatic engine-restart operating mode at which the engine is cranked by the motoring operation and then started up by initiating timely a fuel-injection operation after initiation of the rotational speed feedback control. The controller includes a combustion-stability decision section determining whether the engine is in a stable combustion state, and a feedback gain switching section switching a feedback gain for the rotational speed feedback control between high and low feedback gains, depending upon a combustion state of the engine. <IMAGE></p> |
