Abstract
A method of applying energy optimum control (EOC) when the hybrid electric vehicle performs position control has been developed. As a method of deriving an optimal control law suitable for position control, we attempted a method of adding a virtual drive system driven by a position error signal in the model to be controlled, adding its power consumption to the evaluation function and deriving an optimum control law. In the simulation of the preceding vehicle follow-up, good trackability was not obtained in the rule-based control (RBC) of the comparison, but good follow-up results were obtained in the EOC. The engine energy consumption for EOC was only 85.7% of RBC. In the simulation of the target position stopping, energy consumption was effectively suppressed by the function of the efficiency function of the engine and the motor in the EOC. As a result, the EOC consumed about 92% of the RBC's engine energy consumption.
