During an idle stop the target compression ratio is set to an idle stop restart compression ratio (?is). During a sailing stop the target compression ratio is set to a sailing stop restart compression ratio (?ss). The sailing stop restart compression ratio (?ss) is lower than the idle stop restart compression ratio (?is).
