IV. Working principle

1. Electronic Throttle and Fly-by-wire Throttle

Along with rapid development of auto industry, auto manufacturers in America,  

Germany, Japan and other countries successively adopted electronic throttle control  

system early in 1990s. Electronic throttle control system mainly consists of throttle  

pedal, pedal displacement sensor, ECU (electronic control unit), data bus wire, servo  

motor and choker executing mechanism. Electronic throttle is generally adopted in  

fairly new models. Electronic throttle is named in comparison with fly-by-wire throttle  

which features direct connection between throttle pedal and choker with thin steel  

wire. The treading depth of throttle pedal directly corresponds to the opening width  

of choker. Electronic throttle is free of wire. Treading depth of throttle will be converted  

into resistance value after a potentiometer (with variable resistance) is mounted in  

pedal. Electronic system of automobile indirectly determines the depth of pedal through  

sampling of resistance value. Finally, ECU will activate stepping motor to control the  

opening width of choker. It can be easily found through principle comparison that fly-

by-wire throttle features simple system and direct control, with the proportion of the  

opening width of throttle and choker being 1:1. Characteristics of electronic throttle  

are as follows: throttle pedal only indicates driver’s operating intention, while the  

final right to control choker belongs to ECU.

2. Characteristics of Electronic Throttle Control System and ECU(ECU)

In models with electronic throttle control system, ECU will analyze the treading depth  

of throttle in combination with auto conditions when controlling electronic choker, and  

then calculate appropriate opening width of choker at the current time. When diver  

speeds up suddenly at the time of startup (tread the pedal to the utmost), ECU will  

perform analysis according to the current auto speed, opening width of choker and  

other factors, appropriately restrict the opening width of choker from the perspective  

of fuel saving and reasonable exhaust emission, and control fuel spray system to  

restrict maximum spray of fuel injection nozzle at the same time. In this way, driver  

will feel that automobile begins to start after throttle is treaded for a while, which is  

the so-called throttle lagging. Therefore, throttle lagging is actually the result of ECU  

operation through restricting instant output of engine, which can make automobile  

more environmental-friendly and energy-saving.


3. Operating Principle of STRONG BOOSTER

(1) Accelerating choker opening and improving static response

“Acceleration” of STRONG BOOSTER is realized mainly through improving the responding  

sensitivity of choker. When ECU finds that driver has the intention for acceleration, it  

will activate rapid opening of choker via circuit signals to improve the responding  

sensitivity of throttle.

(2) Speeding up throttle signals and improving dynamic response

When accelerator treads on throttle pedal, STRONG BOOSTER will calculate the alteration  

rate of throttle signals according to treading depth and time. Alteration rate is in  

proportion to accelerating requirements. STRONG BOOSTER will enhance such alteration  

rate and finally realize maximum dynamic response of auto acceleration.

(3) Providing false driving style for ECU’s adjustment of engine parameters

ECU of modern engine generally has the capacity of self-adapting driving style. If  

driver often treads on throttle quickly to a considerable depth (also known as pulling  

speed), ECU will gradually consider that the driver’s style tends to be “violent”. In this  

way, engine will slowly adjust choker and fuel spray system, etc. to obtain optimal  

adjusting parameters of engine under this style. After STRONG BOOSTER is used for a  

long time, even if the driver drives the car with previous “mile” driving style, engine  

will still acquire experience of “violent” driving, which is equivalent to the adjustment  

of ECU parameters. At the long last, engine will automatically amend its parameters  

to adapt to such driving style.
