Utility
Voltage control for alternator mode in electrified vehicles
17 Aug 20
A system comprises a high voltage (HV) battery system connected to an HV bus, a motor generator unit (MGU) connected to the HV bus, a main contactor disposed on the HV bus between the MGU and the HV battery system such that, when the main contactor is closed, the HV battery system stabilizes a voltage of the HV bus, a low voltage (LV) battery system connected to an LV bus and configured to stabilize a voltage of the LV bus when the main contactor is open or malfunctioning, a direct current to direct current (DC-DC) converter connected to the HV bus and the LV bus, and a controller configured to (i) when the main contactor is closed, control the DC-DC converter to stabilize the LV bus voltage, and (ii) when the main contactor is open or malfunctioning, control the DC-DC converter to stabilize the HV bus voltage.

Utility
Disturbance Mitigation Techniques for Hybrid Power-split Transmissions
12 Aug 20
A system and method for controlling a hybrid power-split transmission of a vehicle involve obtaining measured rotational speeds of an engine and an electric motor of the transmission, wherein the transmission comprises at least two input shafts having a gear set therebetween and an output shaft, wherein one input shaft is coupled to the engine and another input shaft is connected to the electric motor, determining a main torque profile for the electric motor based on a set of operating conditions of the vehicle, calculating a speed difference between the measured rotational speeds of the engine and the electric motor, determining a disturbance torque profile for the electric motor based on the calculated speed difference, and performing closed-loop control of the electric motor based on a combination of the main and disturbance torque profiles to mitigate a disturbance at the output shaft of the transmission.

Utility
Predictive Engine Control Methodology for Managing Wheel Slip In Through-the-road Hybrid Vehicles
12 Aug 20
Techniques for managing wheel slip in a through-the-road hybrid vehicle comprise detecting a front wheel slip event based on measured rotational speeds of front wheels, determining a likelihood of a subsequent rear wheel slip event, when the front wheel slip event has ended and the likelihood of the subsequent rear wheel slip event satisfies a calibratable threshold, adjusting a front/rear axle torque split and pre-loading at least one of an engine and a belt-driven starter generator (BSG) unit coupled to a crankshaft of the engine to compensate for a torque drop that is predicted to occur during the rear wheel slip event, and re-adjusting the front/rear axle torque split and pre-unloading at least one of the engine and the BSG unit such that a drop in torque output at a front axle aligns with an end of the rear wheel slip event.

Utility
Vehicle grille shutter system and method of operation
3 Aug 20
A system and method for controlling an active grille shutter system for a vehicle upon startup of an associated engine includes determining if flaps of the AGS system are in a closed position upon cold-startup of the vehicle; moving the flaps to the closed position if it is determined that the flaps are not in the closed position upon cold-startup of the vehicle; and maintaining the flaps in the closed position until an engine coolant temperature (ECT) reaches a predetermined temperature that initially overshoots a predetermined continuous ECT target associated with steady-state operation of the engine.
