Control System for an Automotive Engine and a Method of Controlling an Automotive Engine

摘要

An automotive engine (3) has a start-up state that occurs during a starting sequence and a nm state when operating normally. A starter unit, in the form of a motor (7), cranks the drive unit during the start-up state, and a first energy storage device, in the form of a supercapacitive device (8), supplies electrical energy to the motor (7) during the start-up state. A second energy storage device, in the form of a battery (5), supplies electrical energy selectively to the device (8) other than during the start-up state, and an electrical supply unit, in the form of an alternator (6), selectively supplies electrical energy during the run state to the device (8).
