Abstract

The invention relates to a hybrid electric vehicle reinforcement learning energy management control method. According to the hybrid electric vehicle reinforcement learning energy management control method, by combining an equivalent consumption minimization strategy and a reinforcement learning algorithm and optimizing fuel consumption and battery capacity degradation, a target of optimal use cost of a whole hybrid electric vehicle is achieved. The hybrid electric vehicle reinforcement learning energy management control method comprises the following steps of 1) collecting vehicle state and battery state data; 2) establishing an ICE (Internal Combustion Engine) model, an EM (Electric Motor) model and a transmission system model of the hybrid electric vehicle, a battery internal resistance model and a battery degradation model; and 3) combining the equivalent consumption minimization strategy and the reinforcement learning algorithm, establishing a hybrid electric vehicle energy management strategy, calculating a multi-target optimization problem, and generating a control signal according to a calculation result to distribute engine power and motor power.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicle energy management, in particular to a hybrid electric vehicle enhanced learning energy management control method. Background technique [0002] Today, gasoline, diesel and other fuels used by traditional fuel vehicles are facing a crisis of depletion. At the same time, vehicle exhaust emissions are also causing more and more serious pollution to the environment. New energy vehicles have become an inevitable trend in the development of vehicles. As a form of new energy vehicles, pure electric vehicles still have many problems that have not been effectively resolved in terms of cruising range, battery life, and cost of use. As a form of transition from traditional fuel vehicles to pure electric vehicles, hybrid electric vehicles (Hybrid Electric Vehicles, HEVs) have become the focus of current research in the automotive field. [0003] The power system of a hybrid electric vehicle is composed...
