摘要： A vehicle includes a hybrid powertrain. The hybrid powertrain includes an engine and an electric machine. In response to a loss of controllability of the electric machine, a controller is programmed to operate the powertrain in a limited operating mode. In the limited operating mode, the powertrain is controlled so that a speed of the engine is within a speed range such that the electric machine generates a current to charge a traction battery. In response to a loss of communication with a power inverter that controls the electric machine, the powertrain is controlled so that the speed of the engine is within the speed range and the current flowing to the traction battery is monitored. If the current flow is above a threshold, then the limited operating mode is entered.

摘要： Systems and methods for operating and hybrid driveline are presented. In one example, driver demand torque may be supplied to vehicle wheels via a hydraulic torque path and a friction torque path. Torque is distributed between the friction torque path and the hydraulic torque path in a way that ensures that driver demand torque is met and the friction torque path transfers torque up to its capacity.

摘要： A vehicle includes a regenerative braking system, which may include an electric machine, configured to provide regenerative braking torque to vehicle traction wheels. The vehicle further includes at least one controller configured to provide indicia for display to indicate performance of the regenerative braking system. The indicia represent a comparison of a braking profile that is recorded during a deceleration event and a calculated braking profile that is based on a detected forward object. In various embodiments, the indicia may include a numerical or letter grade representative of a similarity between the recorded braking profile and the calculated braking profile and/or a visual representation of the comparison of the recorded braking profile and the calculated braking profile.

摘要： A vehicle includes an engine, a transmission, and an electric machine configured to provide drive torque and regenerative braking torque. The electric machine is selectively coupled to the engine via a clutch. The vehicle additionally includes a torque converter with an associated bypass clutch coupling the electric machine and transmission. The bypass clutch has an associated torque capacity. The vehicle further includes a controller. The controller is configured to, in response to a braking request indicative of an anticipated regenerative braking request, increase the torque capacity prior to the regenerative braking event by a quantity corresponding to an anticipated regenerative braking torque associated with the anticipated regenerative braking event.

摘要： A vehicle includes an engine and an electric machine coupled to a transmission element. The electric machine is also selectively coupled with the engine by a clutch. The vehicle includes a belt integrated starter-generator (BISG) operatively coupled to the engine. An electronic controller includes one or more inputs adapted to receive a temperature measurement and a request to start the engine. The electronic controller is programmed to energize the BISG and the electric machine in response to receiving an engine start request and a temperature measurement being less than a threshold temperature measurement. The electronic controller is further programmed to close the disconnect clutch to apply torque from the electric machine to the engine in response to the electric machine achieving a threshold electric machine speed.

摘要： According to one embodiment of this disclosure, a vehicle having an electric machine and at least one controller is described. The electric machine may be configured to generate creep torque to move the vehicle. The controller may be programmed to decrease a target speed of a torque converter impeller to create a desired brake torque and partially cancel the creep torque without application of friction brakes in response to a brake pedal being pressed while an accelerator pedal is not being pressed.
