  • LOW-VOLTAGE BATTERY CHARGING SPLIT OF HYRBID VEHICLES WITH BELT INTEGRATED STARTER-GENERATORS
    Publication number: 20180093656
    Abstract: A vehicle includes an electric machine, a starter-generator, and a controller. The electric machine is coupled to a traction battery via an inverter. The starter-generator is mechanically coupled with an engine and electrically coupled with a low-voltage battery. And, the controller charges the low-voltage battery with power from the traction battery, and in response to a torque demand of the electric machine falling below a threshold defined by losses of the inverter, transitions to the starter-generator to charge the low-voltage battery.

  • Perceiving Roadway Conditions from Fused Sensor Data
    Publication number: 20180067487
    Abstract: The present invention extends to methods, systems, and computer program products for perceiving roadway conditions from fused sensor data. Aspects of the invention use a combination of different types of cameras mounted to a vehicle to achieve visual perception for autonomous driving of the vehicle. Each camera in the combination of cameras generates sensor data by sensing at least part of the environment around the vehicle. The sensor data form each camera is fused together into a view of the environment around the vehicle. Sensor data from each camera (and, when appropriate, each other type of sensor) is fed into a central sensor perception chip. The central sensor perception chip uses a sensor fusion algorithm to fuse the sensor data into a view of the environment around the vehicle.

  • Current based six step control
    Patent number: 9849806
    Abstract: A vehicle powertrain includes a DC-DC converter and a controller. The DC-DC converter is coupled between a traction battery and an inverter for an electric machine. The controller is configured to, in response to a rotational speed of the electric machine dropping below a back EMF threshold speed, transition to a current control based six step inverter mode and operate the DC-DC converter to output a voltage less than an open circuit voltage of the traction battery.

  • Power split hybrid electric vehicle motor torque control using state estimation
    Patent number: 9809213
    Abstract: A vehicle includes a traction motor coupled to a driveline. An engine and a generator are coupled to the driveline through a planetary gearset. A controller commands the traction motor torque based on a difference between a driver torque demand and an estimated powertrain torque. The estimated powertrain torque is based on an error between actual and estimated engine speed and an error between actual and estimated generator speed. The estimated powertrain torque may be further based on commanded or estimated engine torque and generator torque. The estimated powertrain torque may utilize a state estimator to calculate internal states based on the errors.
