Claim 0:
1. A drive-by-wire chassis cyber-physical system (CPS) under an intelligent traffic environment, comprising:
a Strength of Signal (SoS)-level CPS, a system-level CPS, and a unit-level CPS, wherein data transmission is realized between a plurality of unit-level CPSs and one system-level CPS, and data transmission is realized between a plurality of system-level CPSs and one SoS-level CPS;
the unit-level CPS is a drive-by-wire chassis and comprises: a driver input module, a basic control module, an execution module, and an environment perception module;
the driver input module comprises: an accelerator pedal and a stroke and force sensor thereof, a brake pedal and stroke and force sensor thereof, a steering wheel and a steering angle and torque sensor thereof, and a wheel steering angle sensor, for perceiving driving, braking and steering information input by a driver to a vehicle, so as to realize extraction of a driver operation intention; one or more computer processors configured to
process data collected by each sensor, formulate an optimal traveling strategy according to a current working condition, and transmit the optimal traveling strategy to the execution module;
receive the optimal traveling strategy of the basic control module, and manipulate the vehicle;
perceive information outside the vehicle and information about a road condition ahead; position the vehicle; and provide vehicle-to-vehicle communication and vehicle-to-base station communication so as to obtain real-time working condition information in a vehicle traveling process;
to supervise a driving behavior of vehicles loaded with drive-by-wire chassis on the same road;
obtain sensor data of the supervised drive-by-wire chassis and execution information issued by the one or more computer processors, obtain a local optimal solution under a current working condition through information interaction and real-time analysis, and issue a control signal; and to monitor and diagnose a driving situation of the vehicles loaded with the drive-by-wire chassis;
perform data transmission with each supervision platform through Internet; and
store data transmitted to the big data platform; transmit the sensor data and the execution information between the drive-by-wire chassis and the one or more computer processors; and to analyze the data transmitted to the big data platform, so as to obtain an ideal operation of the drive-by-wire chassis, and judge whether a driving operation of the drive-by-wire chassis is an ideal operation.
