Abstract

Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission are described. In one example, regenerative torque and torque of an electronically controlled differential clutch are adjusted to increase utilization of a vehicle's kinetic energy.

Description

technical field [0001] The present invention generally relates to methods and systems for controlling a driveline of a hybrid vehicle. The method and system may be particularly useful for hybrid vehicles that include electronic limited slip differentials. Background technique [0002] A hybrid vehicle may provide regenerative braking and friction braking to slow the hybrid vehicle. The electric machine is applied during regenerative braking to slow the hybrid vehicle and convert kinetic energy of the hybrid vehicle to electrical energy. Friction brakes may be utilized when the hybrid vehicle's regenerative braking capacity alone is insufficient to stop the hybrid vehicle. However, using friction brakes can dissipate the kinetic energy of a hybrid vehicle by converting it into heat instead of electricity. Accordingly, it may be desirable to activate and utilize regenerative braking whenever it may be desirable to decelerate the hybrid vehicle. However, sometimes a hybrid ...
