Document Type and Number:
WIPO Patent Application WO/2018/047866
Kind Code:
A1
Abstract:
A control device (24) applied to a vehicle wherein an engine is automatically stopped when a prescribed automatic stopping condition is satisfied, and the engine is automatically restarted when a prescribed restarting condition subsequently is satisfied, said control device controlling a rotary electric machine (21) which has a power generation function based on the rotational force of the engine, and to which excitation current is supplied from a transistor chopper excitation circuit (23) wherein a first pair of opposing arms in a bridge circuit are configured from power transistors (Spa, Snb), and a second pair of arms are configured from diodes (Dna, Dpb). During automatic stopping of the engine the control device (24) executes a first grounding control wherein, among the first pair of arms, the power transistor (Snb) connected to the earth-side of the rotary electric machine is turned on, and the power transistor (Spa) connected to the output terminal side of the rotary electric machine is turned off.
