Modern automobile (vehicle) engineering control techniques is moving towards the direction of line control motion control in development.Developing vehicles line control system mainly consist of two types:which is hydroelectric compression line control system (EHB) and electronic machine line control system.Hydroelectric line control systems is the product of combining an electronic system and a liquid compression system,the electron system gives a soft control,while the liquid compression system yields the force for the engine,and is a transformation from a traditional control system to an electronic control sytem,and if any electronic components malfunctions,the liquid compression system can still finish the control process; electronic machine line control system uses electricity as the main energy source for the vehicle,the engine controls the motor directly,this system eliminates the liquid compression pipelines and the connection between the control pedals and the steering wheel,in order guarantee engineering safety,electronic machine line control system (EMB) must have a large margin of error control function.
The unique points of a vehicle line control motor system is:to be able to distinguish the engineering force for each wheel; the time required for the controller to go into effect is short.Efficient response time,short controlling distance,and a good,stable control quality; can conveniently realize the functions of the automatic brake system and automatic slide resistance,etc.Because line control system contains all the aforementioned advantages,therefore,line control motor system is a publicly recognized developing direction for future vehicles internationally.
Introduced the research of line control system at the present,and how the line control motor system (electronic liquid compression system and electronic machine engineering system) came to be,the composition and originating characteristics,discussed line control motor system's key techniques and development.
