Hybrid vehicle with dynamically-allocated high-voltage electrical power

摘要

A vehicle includes a high-voltage (HV) battery pack, an HV electric traction motor, an additional HV system such as suspension motors of an active suspension system, sensors, and a controller in communication with the sensors. The controller dynamically allocates HV power from the battery pack between the traction motor(s) and the additional HV system using signals from the sensors. Signals may include steering angle, acceleration, and throttle request. A method includes measuring input signals using sensor(s) and processing the measured input signals, including comparing each of the measured input signals to a corresponding threshold. The method also includes allocating some of the HV power from the battery pack via between the traction motor(s) and the additional HV system when the values of any one of the input signals exceeds a corresponding threshold.

1. A vehicle having a transmission, the vehicle comprising:
a high-voltage battery pack, wherein the voltage output of the battery pack is at least 48 volts; at least one electric traction motor; an additional high-voltage system, wherein the at least one electric traction motor and the additional high-voltage system are both electrically connected to and powered via the high-voltage battery pack; a plurality of sensors collectively generating input signals, including a throttle request; and a controller in communication with the plurality of sensors, and having a processor and tangible, non-transitory memory on which is recorded instructions for dynamically allocating power from the high-voltage battery pack between the electric traction motor and the additional high-voltage system; wherein the controller receives and processes the input signals, via the processor, and dynamically allocates the power from the high-voltage battery pack, in real-time while the vehicle is in operation, as a function of the values of the input signals during at least one of a shift of the transmission and a calibrated amount of the throttle request.
