The parking and start-up of the car, even if it is turned off and the short-term parking, are often encountered in daily driving. From the traditional hand brakes, starting, these will be too cumbersome, and now with the continuous development of automotive technology, these are In the improvement, automatic parking, automatic start and stop are all very convenient for the owner!
What is the difference between engine start-stop technology and automatic parking?The start and stop of the engine is enabled by default, and the automatic parking function needs to be manually turned on. I usually turn on the automatic parking function when I start the car.
The start and stop of the engine is conditional. Generally, the brake can be started and stopped automatically after two seconds of braking. However, the automatic parking function is to automatically park the vehicle as soon as the brake is pressed. During this interval, the brake engine is released. It does not automatically start and stop, and the automatic parking function is effective.
If the driving habits do not apply to the person in this car, you can turn off the start-stop function. If it is applied, it is completely accustomed to use it properly. The two do not conflict.
Starting and stopping itself is conditional. I also know that what everyone usually talks about is that when the brakes are applied, the engine stops, the automatic parking is enabled, the brakes are not activated, and the automatic parking is effective, right. The basis of the start and stop is designed under the condition that the brakes are not moving, and it is impossible for both to take effect at the same time. Unless it is a hybrid car that starts with electricity, it is possible to achieve synchronization.
The automatic parking, that is, the AUTO HOLD function of the vehicle, is generally behind the electronic handbrake. Moreover, the electronic handbrake is interlocked with the AUTO HOLD, and sometimes the electronic hand brake is involved in the use of the AUTO HOLD.
However, AUTO HOLD realizes parking brake not by electronic handbrake. It relies on intelligent brake system. The vehicle must have brake control system such as ESP. Because the AUTO HOLD itself is an extended function of the ESP, it is controlled by the ESP component. Generally, when the traffic light stops for a short time and starts up very quickly, the parking brake is completed by the ESP control brake. If the time is long, the electronic handbrake will intervene to brake.
When you need to stop when you step on the brakes, the computer will judge the driving condition at this time and apply an appropriate braking force to the vehicle to make the vehicle stand still. When you want to move forward, the electronic system will detect the depth of the accelerator pedal to determine whether to release the brakes. Simply put, if your car has the AUTO HOLD function, you don't need to hang the N block and pull the hand brake when you wait for the traffic light. Control the throttle and brake.
Automatic start and stop is a very good function developed by the manufacturers for fuel economy, but now it is the most vomited. The first thing after many owners start the vehicle is to turn off the start and stop. Why is this?
This has to start from the work of automatic start and stop. Vehicles with start-stop function generally use a reinforced motor. When the engine is idle, the engine is completely turned off and does not work, but it does not affect the work of air conditioning and sound in the vehicle. When it is necessary to advance, the engine is re-ignited.
It is in this re-ignition start process, it is more annoying, because some cars start with loud sound and large jitter, which greatly affects the driving experience; some cars even have to wait a second or two to re-ignite, the rear horn sounds one after another . Therefore, it is a consensus to get off the bus and start and stop.
These are two completely different features.
The automatic start and stop of the engine is automatically turned off when the vehicle is temporarily parked during driving (for example, waiting for a red light). When it is necessary to move on, the system automatically restarts the engine's system. The English name STOP&START is referred to as STT. The STT Intelligent Fuel Economy System is a system that controls engine start and stop.
The automatic parking system is a function that automatically pulls the handbrake for you. After starting this function, for example, when parking at a traffic light, it is equivalent to no need to pull the handbrake. This function is especially suitable for downhill and frequent start and stop. The electronic handbrake is also the electronic parking brake system. The Electronic Park Brake (EPB) is a technology that integrates temporary braking during driving and long-term braking after parking, and implements parking braking electronically.
Still others are worried that frequent ignition starts will have any effect on the engine? Generally speaking, there is no problem, because when the traffic light is waiting for the flame, it will be tens of seconds, the engine temperature is still high, and the oil can be smoothly lubricated, with little effect.
In fact, automatic start and stop is very helpful for fuel economy. According to the authoritative organization, cars with automatic start-stop function can save 10% to 15% of fuel every year. This is a considerable amount of data. Let's go. By the way, please stop the start and stop!
Whether it is automatic parking or automatic start and stop, it is a function that we can develop better with the car. If we can use them effectively, not only will it be more convenient to drive, but it will also save a lot of money.
