What is the difference between D and S files in the automatic file?

Most automatic cars will have s, so what's the difference between D and S? Overall speaking, it is the difference in automatic control logic for shifting. In general, S is the performance orientation and D is the comfort/economic orientation.

D is the forward gear, which is the gear position for all models. When this gear is running, the hydraulic system control device automatically turns on the corresponding forward gear according to the throttle opening signal and the vehicle speed signal. The planetary gear transmission is executed during the gear shift. The corresponding gear ratio is obtained under the control of the component. The whole process runs exactly according to the set logic.

The S-segment is also known as the sport. When this gear is operated, the hydraulic control system can only connect the first and second gears of the forward gear, and the automatic transmission can only automatically shift between these two gears. Ascended to a higher gear, so the power of this stall is even stronger. Then in the usual driving process, what are the differences between D and S files?

S is more responsive than D

The S-block is Sport Sport, and the shift logic of the computer will change when the S-block is hung, and the upshift will be delayed. For example, in the process of driving, suddenly stepping on the accelerator S file will respond quickly, but the D block will first wait a bit to see if the owner is not careful only stepped on the retreat, to confirm the understanding of the owner is really anxious The downshift will only be performed when accelerating.

There is also a part of the car that will associate the control of the S-block and the electronic throttle, so that the S-block will provide better throttle response, and even adjust the throttle depth and engine load mapping, so that the same deep-throttled engine output is higher to give power. Better feeling.

S gear is more fuel efficient than D gear

When in the S position, the high fuel injection volume, so the car's fuel consumption will inevitably increase, although that can be an instant speed, but this gear is mostly used in overtaking, this kind of The gear is actually a time-delay upshift without changing other work steps. This will bring more load to the gearbox and it will wear out to the gearbox.

S and D shifts

Because of the strong power of the S gear, it is usually switched to this gear in the field or when climbing. In the usual driving, it is more in the D position, which is more economical and comfortable. After all, the S gear is more fuel-efficient, and it is easy to wear out. box.
