How to cruise at a constant speed by car?

First of all, why do cars have the function of cruise control? In fact, the original intention of this functional design is to liberate the driver's feet. His function is to automatically keep the speed at a fixed speed without stepping on the accelerator pedal after turning on the switch at the speed required by the driver.

Constant speed cruise function has appeared in many cars from the initial high-end cars.

However, some surveys show that although many riders know that their cars have cruise control function, only about 10% people actually use it, and some even don't use this function at all.

Many people choose to use it when running at high speed, and some people say that they choose to use it because it saves fuel, but there are still many people who choose not to use it for safety reasons. So is cruise control worth using? Let's first look at the control principle of the cruise system.

Working principle of constant speed cruise

The cruise control unit (ECU) automatically adjusts the throttle opening according to the vehicle speed set by the driver, the signal of the vehicle speed sensor and the corresponding instructions, so as to keep the vehicle running at a constant speed. Specifically, after the driver sets a certain vehicle speed through the control switch and accelerator pedal, the cruise ECU compares the actual vehicle speed signal input by the vehicle speed sensor with the set vehicle speed stored in the memory. When there is a difference between the two vehicle speeds, the cruise ECU outputs a control command to make the actuator act through the drive circuit to increase or decrease the throttle opening, so that the car can run at a constant speed at the set vehicle speed.

Generally speaking, constant speed cruise is to use advanced electronic technology to automatically adjust the speed, and then make the car run at a constant speed according to the set speed.

Turn on the constant speed cruise and set a speed, and your feet will be liberated. You don't have to step on the accelerator all the time, and you can save fuel by adjusting the throttle opening through the intelligent system.

After this, I believe you have a general understanding of cruise control, so how to turn on the cruise control function?

How to turn on the cruise control function?

The steering wheel designed by each car brand is different in shape, so the switch style and position of cruise control are also very different, but its control switch is generally arranged near the steering wheel.
