On-board Time-independent Battery Usage Data Storage
11 Mar 21
Time domain battery usage data of a battery of an electrified powertrain of a vehicle in terms of average SOC, DOD and a set including average current flow rate and average battery temperature for each charge-discharge full cycle and half cycle of the battery during a use period are used to identify a location in a 3-D storage matrix (of fixed size and predetermined discretization levels for each dimension) in memory of an electronic control unit and a count in that location incremented.

Torque Distribution Control to Improve Steering Performance In Through-the-road Electrified Vehicles
25 Nov 20
Torque distribution control systems and methods for through-the-road electrified vehicles having distinct first and second torque generating systems for distinct first and second axles, respectively, utilize existing vehicle sensors to (i) obtain measured wheel rotational speeds and a measured steering wheel angle, (ii) estimate virtual yaw rates of the first and second axles using these measured values and other known vehicle parameters, (ii) predict whether oversteer or understeer of the vehicle is likely to occur based on the estimated first and second axle virtual yaw rates, and (iv) when oversteer or understeer of the vehicle is predicted to occur, adjust a torque distribution between the first and second torque generating systems to prevent the oversteer or understeer from occurring and to keep the vehicle on a constant turn path.

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.

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.
