More Information
Summary:A hydraulic control system for a transmission is provided. The hydraulic control system includes a source of pressurized hydraulic fluid that communicates with an electronic transmission range selection (ETRS) subsystem. In one example, the ETRS subsystem includes an ETRS enablement valve, an ETRS control valve, a park servo that controls a park mechanism, a plurality of solenoids, and a park inhibit solenoid assembly. 本发明涉及种自动变速器液压控制系统中的电子变速器范围选择子系统。提供了种用于变速器的液压控制系统。该液压控制系统包括与电子变速器范围选择（ETRS）子系统连通的加压液压流体源。在个示例中，ETRS子系统包括ETRS启用阀、ETRS控制阀、控制停车机构的停车伺服器、多个电磁阀以及停车禁止电磁阀组件。
