Parking and waiting for a red light is an essential part of driving technology. However, for automatic transmission vehicles, there has been controversy as to whether or not to select the gear position as N-gear. Discussions on this issue remain inconclusive. However, as a representative of the veteran drivers, I will do my best to answer this question and make it clear whether the red light for automatic transmission vehicles to stop and wait for the red light must be in N gear.
First: the working principle of automatic transmission vehicles.
Before the necessity of putting on N gear, let's first understand how automatic transmission vehicles work. Automatic transmission vehicles use hydraulics and an electronic control unit (ECU) to shift gears. It intelligently selects the right gear based on parameters such as vehicle speed, pressure on the accelerator pedal and engine speed. When shifting gears, the hydraulic system cuts off the transmission between the engine and the drive wheels before re-establishing the connection. As a result, automatic transmission vehicles usually choose either N or P gear when parking.
Second: Why choose N gear?
Many people believe that it is reasonable to choose the gear to be n when parking and waiting for a red light. This is because the n-gear means "neutral", which does not transfer the power of the engine to the drive wheels, thus reducing friction and wear on the rotating parts. In addition, the N-gear can also reduce the pressure on the clutch and extend its service life. In addition, when the vehicle is in N gear, the engine speed can be reduced to a minimum, which can save fuel consumption.
Third: Is it necessary to hang N gear?
Although there may be some benefits to hanging in nth gear, it is not necessary in all cases. For example, in some automatic transmission vehicles, the hydraulic system automatically cuts the connection between the engine and the drive wheels, which can achieve an N-like effect even when it is hung in D gear. In addition, modern automatic transmission vehicles usually automatically switch gears to N or P gear when parked, so the driver does not need to operate it manually.
However, in some special cases, it may be beneficial to choose the hanging position as the nth gear. For example, if you need to wait a relatively long time, putting N gear will reduce clutch wear and save some fuel. In addition, on some steep slopes, choosing the mount in N gear can avoid the vehicle slipping back and provide better safety.
In summary, there is no fixed answer to whether automatic transmission vehicles must be in N gear when parking and waiting for a red light. Although nth gear may have some protection for the vehicle and driving components, the technology of modern automatic vehicles is advanced enough that nth gear is not necessary. Therefore, it is a very reasonable choice to decide whether to hang N gear according to the actual situation and personal preference.
Regardless of whether they are in N gear or not, drivers should always pay attention to traffic rules and safety. When parking at a red light, it is more important to maintain proper distance between vehicles and use the brakes and accelerators as required. Only when each of us does our part can we work together to create a safer and smoother road environment.
