附录  A1  Wire control technology in car use
1.Line Control Move (Volkswagen wire) By
Line control servo system powered by realize electronic device, control device, gearing, brake four parts. ECU (electronic control units) for brake system for overall control by new electronic brake, each brakes have their own control unit. Mechanical connection reduce gradually, the brake pedal and brake the power transfer between separated, to be replaced by wire, wire transfer energy, cable relay signals. Line control move in cars since ABS since widely used on the braking system of once again skip-type development.
Current line control servo system is divided into two types: one is the electro-hydraulic braking system hydraulic EHB (Electronic - Volkswagen), another kind is Electronic Mechanical braking system Mechanical EMB (Electronic - Volkswagen). Electric hydraulic brake system of electronic and hydraulic system is to combine electronic control system, by hydraulic system provide motivation; Electronic and mechanical braking system will replace traditional brake system with wire the air or brake fluid force transmission medium, such as electric brakes to replace traditional brake, electronic and mechanical bra
king system is the development direction of future braking system. Line control servo system is the common features is Angle with the pedal force can step by step; the proportion of electronic control Has control of braking torque and pedal Angle corresponding program control unit; Program control unit can be based on other sensors or controller input signal active braking and other function realization.
2. Wire Control Steering System
Wire control Steering System referred By Steering SBW (By Wire System), it has the function of the network connection fault-tolerant control unit, actuators and sensors and redundancy of electronic control units, cancel the Steering dish and Steering wheel mechanical connection between entirely By electricity, realize Steering, from the traditional Steering System of various restrictions. Not only can free design of steering force transfer
characteristics, but also can design the horns of the vehicle steering transmission characteristics, the design of steering characteristics to bring infinite space.
The driver turned to the disk operating, turning to dish sensor test driver's steering data (yaw angles sensors, camera, etc), to turn auxiliary system detection data, providing environmental ECU to data an
d environmental testing data through the network bus real-time transmission to the electronic control unit ECU, ECU to data and in accordance with the driver detection data, environment controlling steering actuators action achieve turning and will wheel corner, torque and road such as feeling of feedback to drivers, to ensure that the steering system reliable safety and system has set up redundancy electronic control units, in emergency situations, the system will ignore error messages, make the vehicle safety running smoothly.
3. Line Oil-control Door
Line oil-control door, also called electronic throttle, namely engine accelerator is through electronic control. The traditional throttle control mode is the accelerator pedal, drivers through by throttle levers of direct control engine accelerator open degree, thus decided to speeds up or slows down, the driver action and throttle action is through bars between the role of the mechanical connection. And with electronic connection line oil-control door instead of mechanical connection, the pilots on the accelerator pedal control by still pull rod, rod is not straight , but one received throttle attached to an accelerator pedal position sensor, the position of rod sensor that will change into electrical signals transmitted to the electronic control unit, automotive electronic control unit will to collect relevant sensor signal processed sends commands to throttle actuators control module, throttle actuators contr
ol module to send signals to the throttle actuators, thus control throttle opening-closing degree. That is the driver with throttle action of action between the electrical signals by electronic components is connected. Line than traditional throttle control oil door way according to precise, engine running of the various auto finely tuned into the cylinder of information, the fuel air mixture, improve engine combustion status, which greatly improve the performance and fuel economy of car.
Toyota models adopted in Lexus all electronic thread oil-control door systems, have 2 accelerator pedal position sensor, all send data to the engine control unit ECM, if one of the accelerator pedal position sensor no signal, car can still driving, and engine warning
light; If two accelerator pedal position sensor are no signal, the engine working in idle state. Line of oil door system according to the driver intention of action, analysis the driver, accurate control of the throttle and increase the driving stability and dynamic economy.
In the new generation of accord sedan V6 engine 2.4 L and 3.0 L had adopted line on new technology of oil door. Through the sensor to monitor the accelerator pedal position of power control, ECU. Its advantage is improved started smooth, improved fuel efficiency engine response, defect is a slight lag. In addition the wire control technology brings another advantage is that fixed speed cruise function, its control key is integrated in on steering wheel, simple operation is convenient.
Honda motor company Civic series to the eighth and evolution of 2005. The vehicle adopted 1 four cylinder engine, 1.8 L newly developed 1.8 cixin Li - VTEC control variable valve timing (intelligent and lift) inline 4 cylinder engine can burst 103kW for maximum power peak torque can reach more than 174Nm, almost all the natural inlet type with displacement of domestic models. This engine applied the Honda's latest I - VTEC technology, match with use wire the throttle control technology, can very effectively improve fuel economy, reducing harmful emissions. And intake efficiency and compression ratio are further improved, and made strong output power. Making yuan ECM, if one of the accelerator pedal position sensor no signal, car can still driving, and engine warning light; If two accelerator pedal position sensor are no signal, the engine working in idle state. Line of oil door system according to the driver intention of action, analysis the driver, accurate control of the throttle and increase the driving stability and dynamic economy.
Example: wire control technology in fuel-cell car can drive applications - general HY HY wire control car change traditional mechanical transmission mode of connecting rod, using electronic signals to manipulate throttle, braking and steering mechanism. Canceled the traditional steering dish, throttle, brake pedal all operations are concentrated in a handles with one hand, the pilot can finish all of the operation. When pilots to speeds up or slows down, can promote the handle to the right or to the left; B
raking buttons also installed in the handle, braking click braking button; When cornering, drivers simply up or down push lever.
Electronic wire control device constitute a set of convenient operation control unit that a set of control unit is called "X - drive". It replaced the traditional steering plate etc, with just one hand make drivers can be completed in all haste and slow (brake), turn operation.
Traditional car is through a set of mechanical device, like steering bar etc, the rotation through manipulation steering dish to wheel rotation. Wire control technology is the driver to turn into an electronic pulse instructions, the sensor captures an electronic pulse, the electronic pulse signal is driven by the electronic control motor to make wheel bogie rotation. Line control system is transformed into the instructions driver with the electrical signals, electrical signals to drive motor. Because the software determines the automobile driving characteristics, such as accelerated, deceleration (brake), turn, etc., all work just reproduced, implement the corresponding software programs.
附录  A2  线控技术在汽车上的运用
1.线控制动（brake by-wire）
线控制动系统由实现电子化的供能装置、控制装置、传动装置、制动器4个部分组成。ECU（电控单元）对制动系统进行整体控制，采用全新的电子制动器，每个制动器有各自的控制单元。机械连接逐渐减少，制动踏板和制动器之间的动力传递分离开，取而代之的是电线连接，电线传递能量，数据线传递信号。线控制动是自ABS在汽车上得到广泛应用以来制动系统的又一次飞跃式发展。
目前线控制动系统分为2种类型：一种是电液制动系统EHB （Electronic-hydraulic Brake），另一种是电子机械制动系统EMB （Electronic-Mechanical Brake）。电液制动系统是将电子与液压系统相结合，由电子系统控制，液压系统提供动力；电子机械制动系统则用电线取代传统制动系统中的空气或制动液等传力介质，电制动器取代传统制动器，电子机械制动系统是未来制动系统的发展方向。线控制动系统的共同特点是都具有踏板转角与踏板力可按比例调控的电子踏板；具有控制制动力矩与踏板转角相对应的程序控制单元；程序控制单元可基于其他传感器或控制器的输入信号实现主动制动及其它功能。
2.线控转向系统
线控转向系统简称SBW（Steering By Wire System），它由具有容错功能的网络相连接的控制单元、执行器、传感器和冗余电控单元组成，取消了转向盘与转向轮之间的机械连接，完全由电实现转向，摆脱了传统转向系统的各种限制。不但可以自由设计汽车转向的力传递特性，而且可以设计汽车转向的角传递特性，给汽车转向特性的设计带来无限的空间。
驾驶员操作转向盘时，转向盘传感器检测驾驶员的转向数据（横摆角传感器、摄像机等），向转向辅助系统ECU提供环境检测数据，转向数据和环境检测数据通过网络总线实时传送给电子控制单元ECU，ECU按照驾驶员的转向数据和环境检测数据，控制转向执行器动作实现转向，并将车轮的转角、转矩和路感等反馈给驾驶员，为确保转向系统安全可靠，系统设置了冗余电控单元，在紧急情况下，系统会忽略错误信息，
