Abstract

The invention relates to a multi-target energy management method in HEV self-adaptive cruise based on MPC, and belongs to the field of new energy vehicles. The method comprises the steps that S1, performing HEV following process and power traditional system modeling, calculating the required torque of a whole vehicle at the corresponding moment, and considering an engine emission model; S2, considering each comprehensive performance requirement in the car following process, and respectively calculating cost functions corresponding to the car following safety, the fuel economy and the emissionperformance; S3, adopting an MPC algorithm to predict the required torque of the vehicle at the future moment, and therefore a total cost function in a prediction domain is worked out; and S4, according to the total cost function obtained in the S3, minimizing the target function to obtain optimal torque distribution, so that the engine works in a high-efficiency region. The safety, the fuel economy and the low emission performance of the automobile in the following process are considered, and energy consumption and pollution of automobile emissions to the environment can be reduced while thetraffic pressure is relieved.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and relates to a multi-objective energy management method in hybrid electric vehicle HEV adaptive cruise based on model predictive control (Model Predictive Control, MPC). Background technique [0002] Hybrid electric vehicles (HEVs) have lower energy consumption and fewer harmful emissions than conventional fuel-powered vehicles due to more degrees of freedom provided by reversible energy storage devices and electric motors. In HEVs, the Energy Management Strategy (EMS) has a significant impact on fuel economy. The design and performance of EMS are affected by external factors such as traffic conditions, future traffic information, and road conditions. [0003] At the same time, researchers are vigorously developing technologies for connected vehicles (CAVs). Through vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), these technologies enable vehicles to share and exchange informa...
