LOW LEVEL OIL DETECTION SYSTEM AND METHOD |
摘要 |
A hydraulic system for a hybrid module which is located between an engine and a transmission includes a parallel arrangement of a mechanical pump and an electric pump. Each pump is constructed and arranged to deliver oil from a sump to other portions of the hydraulic system depending on the operational mode. A load on the electric pump corresponds to a current draw on the electric pump motor. This current draw is used to indicate when there is a low oil level in the sump. |
