    摘要: A multi-mode hybrid transmission including a selectable one-way clutch and first and second torque machines transitions to operating in a target continuously variable mode including applying a selectable one-way clutch and controlling input torque and motor torques of the first and second torque machines using a second kinematic relationship. A multi-step process is executed to transition the first clutch to a deactivated state, transition the second selectable one-way clutch to the applied state, and transition to using the second kinematic relationship to achieve a preferred output torque.

    摘要: A vehicle includes a transmission, a motor configured to provide a motor torque to the transmission, and an engine configured to provide an engine torque to the transmission. A torque converter is operably disposed between the transmission and the motor, the engine, or both. The torque converter is configured to at least partially transfer at least one of the motor torque and the engine torque to the transmission in accordance with a plurality of k-factors. The torque converter includes a clutch configured to at least partially engage to change the effective k-factor applied by the torque converter. A control processor is configured to blend the plurality of k-factors and at least partially engage the clutch based on the blended k-factor.

    摘要: More accurate and robust battery state estimation (BSE) techniques for a battery system of an electrified vehicle include estimating a current bias or offset generated by a current sensor and then adjusting the measured current to compensate for the estimated current bias. The techniques obtain nominal parameters for a battery model of the battery system based on a measured temperature and an estimated open circuit voltage (OCV). The techniques use these nominal parameters and the corrected measured current to estimate the OCV, a capacity, and an impedance of the battery system. The techniques utilize the OCV to estimate a state of charge (SOC) of the battery system. The techniques also estimate a state of health (SOH) of the battery system based on its estimated capacity and impedance. The techniques then control the electrified vehicle based on the SOC and/or the SOH.
