Patent number: 11597391Abstract: A vehicle includes an accelerator pedal, an electric machine, and a controller. The electric machine is configured to propel and brake the vehicle according to a one-pedal driving operation. The controller is programmed to, in response to depressing the accelerator pedal, command a desired torque to the electric machine. The controller is further programmed to, adjust the desired torque based on a gradient of a road surface that the vehicle is positioned on. The controller is further programmed to, in response to movement of the electric machine in a direction that is opposite to a desired direction while the adjusted desired torque is being applied, increase the adjusted desired torque by a compensation torque such that movement of the electric machine transitions to the desired direction.Type: GrantFiled: September 28, 2020Date of Patent: March 7, 2023Assignee: Ford Global Technologies, LLCInventors: Sergey Gennadievich Semenov, Jonathan Andrew Butcher, Bryan Michael Bolger, Brandon Jay Woodland

Patent number: 10112596Abstract: 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.Type: GrantFiled: May 18, 2016Date of Patent: October 30, 2018Assignee: Ford Global Technologies, LLCInventors: Jonathan Andrew Butcher, Walter Joseph Ortmann, Francis Thomas Connolly
