How to use cruise control more scientifically

Cruise control can make our driving easier and lower fuel consumption. But there are some drivers with certain misunderstandings about how to use cruise control, which can lead to increased fuel consumption and even leave safety risks for driving.

Cruise control is only suitable for highways or roads with good conditions, and it requires reaching a certain speed before it can be activated. Depending on the vehicle model, the required speed to activate cruise control can vary. On common trucks, the speed to activate cruise control generally needs to be over 40 kilometers per hour.

The operation of cruise control is divided into two types: knob type and button type. Regardless of the type of cruise control, there is usually an on/off button (ON/OFF), cancel button (CANCEL), set the current speed (SET), restore the set speed (RES), speed plus (+), speed minus (-).

When we need to use cruise control, we can follow the steps below:

1. Turn on the cruise control system with the on/off key, and the cruise control indicator light on the instrument panel will be on;

2. Control the accelerator pedal to accelerate to the speed we need to set, or the system is turned on above the minimum speed, press the SET button, then the cruise control will be in accordance with the speed of the SET button to cruise at a fixed speed;

3. When you need to change the cruising speed, you can adjust the speed by "RES+" and "SET-" buttons;

4. There are three ways to release the cruise control, namely, stepping on the brake, pressing the CANCEL button, and pressing the ON/OFF button;

5. If the cruise control is canceled by stepping on the brake or canceling the button, and you want to resume the cruise control set last time, you can press the "RESET CRUISE RES" button to resume.

I On which roads does cruise control make the most sense to use?

The basic function of the cruise control system is to control the vehicle in the "fixed speed" state driving, the engine fuel supply through the computer to adjust, when the road conditions are good, and the driving torque of the rear wheels is greater than the road surface gradient and other resistance, the computer will be based on the current road conditions, speed, driving resistance and so on constantly adjust the amount of fuel supply, so that the vehicle is always in accordance with the set speed. The computer will continuously adjust the fuel supply according to the current road conditions, vehicle speed, driving resistance, etc., so that the vehicle will always drive at the set speed.

When the resistance is greater than the driving force of the tires and the resistance cannot be overcome by injecting fuel, the cruise control normally exits on its own (manual) or by forcing a downshift so that the driving force is greater than the resistance (automatic) and by increasing the engine rpm to keep the vehicle at the set cruising speed.

Therefore, when we use cruise control, it is best to use it on highways with flat roads and less traffic.

Also, since the truck will only drive at the speed we set when the cruise control is on, you should be cautious or stop using the cruise control on the following roads, respectively:

1. Urban roads, ordinary roads or highways with high traffic volume;

2. Rainy days, roads with water on the surface;

3. Snow and ice days, foggy days;

4. Highways with many curves.

When the cruise control is on, if there is a big difference between the current speed and the speed we set for the cruise control, the computer will default to the need to reach the set speed at the first time, and will use the maximum fuel injection to make the vehicle's speed reach the set speed as soon as possible.

For example, if our current vehicle speed is 60 kilometers per hour, and we set the cruise control speed to 80 kilometers per hour, then the computer will "notify" the systems to speed up to 80 kilometers per hour as soon as possible, and the vehicle will experience rapid acceleration. At this time, the vehicle's fuel consumption and safety risks will also rise.

Also, when we need to increase the speed of the car, if the increase is in a small range, such as every 1 km as a unit, we can do it through the + of the cruise control.

But if we want to increase the speed in a larger range, such as 5 kilometers as a unit or a multiple thereof, it is better to increase the speed slowly through the accelerator pedal and then turn on the cruise control instead of achieving it through the cruise control button.

Reasonable use of cruise control can reduce driving fatigue to a certain extent, improve driving safety and reduce vehicle fuel consumption, but cruise control is only suitable for use in some specific road and working conditions, the use of indiscriminate will only increase the safety hazards of driving.
