  • SYSTEMS AND METHODS FOR MANAGING TEMPERATURE OF AN ELECTRIC MACHINE OF A HYBRID ELECTRIC VEHICLE
    Publication number: 20230017528
    Abstract: Methods and systems are provided for operating a driveline of a hybrid vehicle during conditions when a temperature of a motor/generator is increasing. In one example, a method is provided that adjusts engine speed as a function of motor/generator temperature while maintaining engine power output when driver demand wheel power is constant.
    Type: Application

  • Methods and system for controlling engine braking
    Patent number: 10407069
    Abstract: Systems and methods for operating a vehicle that includes a continuously variable transmission are described. The systems and methods adjust engine speed according to one of a plurality of engine speed to vehicle speed profiles so that driveline noise, vibration, and harshness may be reduced. The different engine speed to vehicle speed profiles provide different levels of engine braking.

  • Engine Speed Stabilization
    Publication number: 20180334169
    Abstract: A vehicle includes an engine. The vehicle includes a controller configured to start a timer having a duration defined by a charge limit of a traction battery and during which the engine braking is maintained and reduce a predetermined rate of change speed limit of the engine is reduced. The starting of the timer is responsive to application of an accelerator pedal during engine braking. The controller is further configured to increase the predetermined rate of change speed limit such that engine braking is predicted based on the limit of the battery, responsive to application of an accelerator pedal during engine braking.
