What does the automatic cruise function of a car mean?

refers to the car running at a constant speed. Adaptive cruise control system is an intelligent automatic speed control system developed based on cruise control technology. Because appropriate measures can be taken automatically according to the traffic situation (acceleration, deceleration, braking), so that the adaptive cruise system can adapt well to urban roads with complex road conditions.

Automatic cruise is also known as fixed-speed cruise control system. It allows the driver to drive at a fixed pre-selected speed without operating the accelerator pedal.

The meaning of automatic cruise function is as follows: automatic cruise function, also known as acc, can also be called active cruise in daily life. It is an intelligent car automatic control mode. Such a cruise system can replace the driver to control the speed under certain circumstances, so it can avoid the driver's frequent Cancel and set the cruise operation.

Automatic cruise control (also known as cruise control) is a control system that allows the driver to ensure that the car runs at a stable pre-selected speed without operating the accelerator pedal.

What are the types of automatic transmission cars?

There are four types of automatic transmission car transmission: AMT transmission, 4-speed, 5-speed mechanical hydraulic transmission, speed mechanical hydraulic transmission, and CVT poleless transmission.

There are 3 types of automatic transmission car automatic transmission, namely: automatic transmission (AT).Poleless transmission (CVT). Dual clutch transmission (DSG). Working principle of automatic transmission: Automatic transmission mainly achieves speed change through the combination of fluid transmission and gears.

At present, the power transmission is mostly steel belt or chain transmission. AMT transmission, the abbreviation of electronic mechanical automatic transmission. It is an electromechanical-hydraulic integrated automatic transmission that combines the advantages of AT (automatic) and MT (manual).

At present, there are four main types of the most common automatic transmissions on the market: AT transmission, CVT transmission, AMT transmission and dual-clutch transmission.

At present, there are four types of automatic transmissions commonly used in automobiles, namely hydraulic automatic transmission (AT), mechanical stepless automatic transmission (CVT), electronically controlled mechanical automatic transmission (AMT) and dual-clutch automatic transmission (DCT).

The most common automatic transmissions are mainly the following four: AT transmission: scientific name is hydraulic automatic transmission, which is the most contact automatic transmission. The advantages of AT transmission are obvious, the power is "more direct", and the disadvantages are also relatively prominent, the sense of stuttering when accelerating, and the fuel consumption is relatively high. .

Explanation of automatic transmission car gear

1. Low-speed gear Low-speed gear is the third gear of automatic transmission car, which is selected when climbing hills or passing through muddy roads. This gear will increase the engine speed, so that the vehicle can provide more torque and power output.

2. The explanation of the automatic transmission gear is as follows: D gear: This is the most commonly used gear of automatic gear models, usually with DDThe three types of D3 are similar to the 1st and 2nd swings of the manual transmission, 3rd and 4th gears, 5th and 6th gears. Different types of gears do not need to be controlled manually, and the car will move up and down according to the adjustment of the throttle.

3. Automatic transmission car gears include P gear, R gear, N gear, D gear, S gear and L gear. P is Parking. After the car stops, the P gear vehicle is to brake to prevent movement. Unlike N gear, P gear interrupts the power output. At present, some models will have independent P gear, which is called electronic braking, and the principle is the same.

4. The automatic transmission has P gear, R gear, N gear, D gear, S gear, m gear and L gear respectively.

5. When waiting for the traffic light, you should pull up the handbrake at the same time, and disable the gear when going downhill. L gear: This gear can be used downhill.Or when used uphill, it can limit the gear of the car to the lowest gear, which can make the car use engine power to brake when going downhill. The driver does not need to step on the brake for a long time, causing the brake pads to overheat and cause danger.

6. The explanation of the automatic transmission gear is as follows. 1D gear is the most commonly used gear for automatic gear models. There are usually three types of D1D2D3, similar to manual transmission 1 and 2 swing 3 and 4 gears 5 and 6 gears. Different types of gears do not need to be controlled manually, and the car will rise according to the adjustment of the accelerator. Downshift to 2L gear.
