Research For Control Strategy Of Automobile Automatic Cruise System Based On D2P Motohawk

Automobile automatic cruise system belongs to the vehicle active safety technology,it is the basis of the research and application,automatic and intelligent car and important branch.The technique of control automotive automatic cruise is the expansion and extension of cruise control.It is based on the cruise control,and increased with the vehicle cruise control and based on the safety car collision avoidance warning function.D2 P MotoHawk rapid prototyping system with product level ECU and powerful software platform,can greatly shorten the development process control system,accelerate the research of automatic cruise control strategy.Based on the traditional cruise control strategy based on the analysis of the controller,this paper proposes a new control method.The cruise constant speed mode still adopts control PID control strategy,which is widely used in engineering and summarizes the driver's driving experience car following model is used for the control rules of fuzzy control strategy.Vehicle longitudinal dynamics model is set up in MATLAB/Simulink and completed the software simulation,the control strategy of the feasibility of the proposed algorithm.Also in the study on the control strategy for automatic cruise control system on the basis of using D2 P MotoHawk(From Development to Production,hereinafter referred to as "D2P")software and hardware platform for the Development of cruise control strategy,transplant and implement.According to throttle assembly,D2 P hardware(ECM-0565-128),and use the hardware and software simulation way for the part of the sensor to design of the semi-physical simulation platform,the semi-physical simulation experiment on the D2 P hardware platform,verify the feasibility of the algorithm is combined with hardware and effectiveness.
