Cruise constant speed principle

The cruise constant speed function mainly reads the pulse signal sent by the speed sensor through the cruise control module and compares it with the set speed, and sends instructions through accurate electronic calculation to ensure the most accurate fuel supply for the vehicle at the set speed.

The electronic fuel-saving function is mainly to intelligently control the opening angle and opening time of the throttle, effectively shield the chaotic signals formed by the electronic throttle sensor due to bumpy road sections and bad driving habits, accurately calculate the fuel injection quantity to make the fuel fully burn, and realize fuel saving.

The acceleration function of the throttle is mainly realized by improving the sensitivity of the throttle response. When the system finds that the driver is willing to accelerate, it will drive the throttle to open as soon as possible, thus improving the sensitivity of the throttle response. When the accelerator pedal is depressed, the controller will calculate the change rate of the accelerator signal according to the depression amplitude and time. The faster the change, the stronger the acceleration requirement, which will eventually achieve a faster throttle response speed, and the power sense of the whole vehicle will be significantly increased, which can make the driver feel that the power of the whole vehicle has been greatly improved.

The speed limit setting function, through the controller, sets the maximum value of the output throttle signal according to the speed limit value, and achieves the purpose of speed limit when the throttle output signal exceeds the set maximum value.

Brake failure alarm function, by taking the signal of the brake circuit, will prompt the driver by warning when the brake circuit or brake safety fails.
