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.
