What does HOLD mean on the car? The HOLD on the car means automatic parking assistance system. The HOLD button light is lit to indicate that the automatic parking assist function is turned on, and the vehicle can realize automatic parking; the HOLD button light is turned off, indicating that the automatic parking function is closed, and the car will not automatically park. That is to say, we can realize the opening or closing of the automatic parking function of the vehicle through the HOLD button on the car, and the automatic parking function is not automatically opened.
With the continuous development of automotive electronic control technology, there are more and more intelligent electronic control devices and driving assistance systems on vehicles. If we do not carefully check the vehicle instruction manual with the car, or the user manual, in the use of the vehicle, for some functions on the vehicle do not know how to use, and even do not know that the vehicle has been equipped with some intelligent assistance system. For example, the auxiliary function on a vehicle we are talking about today is the HOLD button function on the vehicle, what does this HOLD mean, and what is the main role? Next, follow the little car dad to see?
THE HOLD on the car, in fact, is the meaning of the automatic parking assistance system, generally known as the automatic parking system, the main function is to achieve the automatic parking of the vehicle, we can simply understand as automatic braking. Generally, on models equipped with electronic handbrakes, there will be a HOLD automatic parking assist system, some vehicles are marked as HOLD on the buttons, and some models are marked with AUTO HOLD. Different logos, meanings and functions are essentially the same.
The implementation of the function of hold automatic parking assistance system is mainly in some specific cases, through automatic braking, automatically maintaining the locked state of the vehicle. For example, when the vehicle starts on the ramp, when the vehicle is parked for a short time, when waiting for the traffic light at the intersection, this function can be used to realize the locking of the vehicle in the case of releasing the brake without switching gears. Then, when we press the accelerator pedal, we can start directly without the need to release the handbrake and switch gears.
Of course, the HOLD automatic parking assistance system is an intelligent auxiliary function installed on the automatic transmission model, and the manual transmission model is generally not equipped. Although HOLD can be understood as an automatic braking function, it is not actually realized by the driving computer operating the braking action on the vehicle. HOLD automatic parking assist is implemented by the ESP system equipped with the vehicle, and the ESP system controls the brakes to lock the vehicle and realize automatic parking, which is an extended function of the ESP system.
At the same time, HOLD automatic parking mainly plays a role in short-term parking, and it is necessary for us to manually operate the HOLD button to open before automatic parking will be realized. Different models will have some differences in the operation of starting automatic parking, some models are locked after the vehicle stops for 1 second, that is, the automatic parking of the vehicle is locked; some models need to be parked after the vehicle is stable, and then deeply press the brake pedal to lock the automatic parking of the vehicle. However, when the vehicle continues to drive, it is only necessary to directly press the accelerator pedal to release the automatic parking and continue to drive.
In addition, after the automatic parking seat is over a certain period of time, the ESP control system will hand over the parking control to the electronic handbrake control, and the electronic handbrake will directly lock the vehicle. Of course, in the process of this switching, the vehicle will not move, it is still in a state of locking, but the control system of the locking has changed.
Combined with the above relevant instructions on the HOLD function on the vehicle, HOLD is actually controlled through the ESP system, and when the vehicle is parked for a short time, the automatic parking function of the vehicle can be realized, which can also be called the vehicle automatic parking assistance system. In the case of starting the HOLD function, when the vehicle is parked for a short time, it can automatically park in a solid line, reducing the operation steps of our parking and starting, and making it more convenient for us to drive the vehicle. Does your vehicle have a HOLD function, and what is the actual experience?
