Vehicle with a start-stop system wherein the starter-generator is directly coupled to the internal combustion engine

摘要

A stop-start system is disclosed for a vehicle comprising an electrical starter-generator (MG,12) directly coupled to the crankshaft of the internal combustion engine (10). The stop/start system comprises a stop/start controller (50) arranged to vary torque produced by the starter-generator (MG,12) during a stop/start event to at least partially compensate for variations in torque produced by the engine (10).
