Abstract: Methods and systems are provided for diagnosing a cylinder valve deactivation mechanism in an engine system having cam-actuated valves. Movement of a latch pin of the deactivation mechanism is inferred from an induction current generated by a solenoid coupled to the latch pin, and the inferred movement is used to diagnose operation of cylinder valve deactivation mechanism. The inferred movement and a profile of the induction current is also used to estimate camshaft and crankshaft timing for improved cylinder fuel delivery in the absence of a camshaft sensor.

Abstract: A vehicle includes a combustion engine (CE) and electric machine (EM) coupled to an energy storage system (ESS) and a controller, which are configured to maximize ESS/battery charge recovery during high performance operation. The controller commands the CE to generate power exceeding road load power and power demand (PD), to recharge the ESS at a maximum rate for rapid ESS charge recovery. Responsive to the PD, the CE generates a maximum power to drive the EM to recharge the ESS at a maximum rate during acceleration, deceleration, and when maintaining velocity of the vehicle, and to generate positive torque and discharge the ESS when PD and road load power exceeds CE maximum power, according to the PD, road load power, and maximum ESS charge rate. Power regeneration during deceleration may also be enabled for the electric machine and/or regenerative brakes, which further maximizes ESS SoC recovery during high performance operation.

Abstract: A hybrid electric vehicle (HEV) and method of operation includes a thermal management system (TMS) that maintains optimal battery temperature operating ranges. The TMS includes a controller, heater, pump, and valves that control a flow rate of a convective fluid about the battery and other components. The TMS responds to battery temperature and differential signals, converting them into pump speed and heater signals utilizing a fuzzy logic multidimensional membership function (MF) that improves performance while reducing energy consumption by generating real-time, smoothed pulse width modulated (PWM) pump speed and heater signals. The MF capability requires less processing power than prior systems, which in turn enables improved response time to battery thermal and temperature rate changes during HEV operation.

Abstract: A table of engine torque correction factors is used to compensate for noise factors. In a hybrid vehicle, the motor is used to measure engine torque during periods of constant transmission input shaft torque. By comparing the measured input torque to the requested engine torque, a controller can update the table of correction factors to compensate for changes in the noise factors. A service procedure may be implemented that systematically provides the controller an opportunity to update many values in the table.
