The invention provides a hybrid vehicle engine brake with manual override. A power split hybrid powertrain includes an electrically actuated brake that selectively engages a ring gear attached to a flywheel. The ring gear may be, for example, a starter ring gear. Engagement of the brake while the engine is stopped permits use of both electric machines to provide torque to vehicle wheels, thereby increasing the electric torque capacity of the powertrain. The brake is mounted for movement relative to the ring gear, and a mechanical linkage is attached to the brake. In the event of a malfunctionof the brake that prevents normal operation of the powertrain, the linkage is manually actuatable by a vehicle operator to move the brake to an override position wherein it cannot engage the ring gear.

    本公开提供了“具有手动超驰的混合动力车辆发动机制动器”。一种功率分流式混合动力传动系统包括电致动制动器,所述电致动制动器选择性地接合附接到飞轮的环形齿轮。所述环形齿轮可以是例如起动机环形齿轮。当发动机停止时所述制动器的接合准许使用两个电机来向车轮提供扭矩,从而增加所述动力传动系统的电扭矩容量。所述制动器安装成相对于所述环形齿轮移动,并且机械联动装置附接到所述制动器。在阻止所述动力传动系统正常操作的所述制动器发生故障的情况下,所述联动装置可由车辆操作员手动致动以将所述制动器移动到超驰位置,在所述超驰位置中,所述制动器不能接合所述环形齿轮。
