Abstract
A method for controlling driveline torque on an electrified powertrain based on obstacle detection is provided. The electrified powertrain includes a first eMotor, a second eMotor and an internal combustion engine (ICE). An obstacle is detected proximate to the vehicle. A proximity signal is communicated to a first torque module that determines a first torque limit. A road surface is detected. A traction limit signal is communicated to a second torque module that determines a second torque limit. A road curvature is detected. A curvature signal is communicated to a third torque module that determines a third torque limit. A safety tolerance is determined based on the first, second and third torque limit. A first torque request is communicated to the ICE. A second torque request is communicated to the first eMotor. A third torque request is communicated to the second eMotor.
