ADAPTIVE ENERGY MANAGEMENT IN A HYBRID VEHICLE
First Claim
1. A hybrid vehicle comprising:
- an engine configured to generate an engine torque;
a battery module configured to store and output electrical energy in accordance with an actual state of charge (SOC);
an electric motor in electrical communication with the battery module, and configured to generate a motor torque based at least in part on the electrical energy received from the battery module, wherein the motor is further configured to generate electrical energy; and
a controller in communication with the engine, the battery module, and the motor, wherein the controller is configured to;
record a drive route;
command a target SOC of the battery module in response to the drive route;
control at least one of the engine and the motor to charge or discharge the battery module as needed in accordance with the target SOC;
record drive information from at least one of the engine and the motor during a current drive route;
compare the current drive route to the recorded drive route; and
adjust the target SOC during the current drive route based at least in part on the recorded drive information when the current drive route is the recorded drive route.

Abstract
A hybrid vehicle includes an engine, a battery module, a motor, and a controller. The controller commands a target SOC of the battery module and controls the engine or the motor to charge/discharge the battery module based on the target SOC. The controller is configured to record drive information during a drive route and adjust the target SOC during the drive route based at least in part on the drive information recorded. A method includes prompting a user to select a drive route, recording drive information during the drive route, adjusting the target SOC based at least in part on the recorded drive information, and controlling the engine and/or the motor to charge/discharge the battery module during the drive route in accordance with adjusted target SOC.
