Economy-oriented Control Strategy for Dual-motor Four-wheel-drive Electric Vehicle in a Car-following Maneuver
Abstract
This paper presents an online economy-oriented controller to improve energy consumption of a two-axel dual-motor 4WD electric bus (E-bus) in a car-following maneuver. The nonlinear model-based predictive control (NMPC) method is applied in this controller to realize a deep fusion of adaptive cruise control (ACC) and torque distribution strategy (TDS). Some search skills are adopted in receding horizon optimization to reduce computing burden. The proposed method reduces energy consumption compared with ACC+TDS method on the condition of ensuring tracking capability.
