Abstract

The invention provides an intelligent electric vehicle adaptive cruise control system and method, and relates to vehicle safety driving assistance control. The system includes an information acquisition module, an operation mode selection module, a control action switching module, a desired torque calculation module, a converter module and an actuator module. A safety distance control strategy anda driving / brake switching strategy are proposed. The neural-fuzzy-based back-stepping sliding-mode adaptive cruise tracking mode control method is adopted, and the nonlinear problem of speed controlof the electric vehicle adaptive cruise control system and the high coupling performance of the system state are solved. The ability of the vehicle tracking a preceding vehicle during adaptive cruisedriving is ensured, the utilization of traffic roads is improved, and the safety and comfort of vehicle driving is improved.

Description

technical field [0001] The invention relates to automobile safety driving auxiliary control, in particular to an intelligent electric vehicle self-adaptive cruise control system and a method thereof. Background technique [0002] Adaptive cruise control (Adaptive Cruise Control, ACC) is a car safety assisted driving system, which adds the function of automatically tracking the vehicle in front on the basis of the traditional cruise control function, so that the vehicle and the vehicle in front can maintain a suitable safe distance, which can improve the safety of the vehicle. Driving safety, ease traffic congestion, and reduce the burden on drivers. At present, a large number of researches on adaptive cruise control systems and control methods focus on traditional vehicles, but less on smart electric vehicles. Intelligent electric vehicle is a current research hotspot, which has the advantages of energy saving and environmental protection. The adaptive cruise function of in...
