Strong booster is for electronic type throttle pedal, fly-by-wire throttle car can’t install Strong booster.
The principle of electronic throttle and fly-by-wire throttle
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.
Strong booster is specially made for resolving the throttle delay response. As per electronic throttle characteristic, the Strong booster has below features:
(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. The input throttle signal will be amplified 50%, that is, the rear 33% of throttle pedal signal is useless at any moment, when driver depress 66% pedal, the Strong booster output is full open throttle, so that the throttle response sensitivity is increased 50%. However Strong booster do not decrease throttle signal grading, just adjust previous 1:1 to 1：1.X, X is the signal amplifying factor.
(2) Amplifying 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.
Strong booster usually has output value within engine rated power, will not harm the cars.
