What is the reason why the automatic gear upshift is too late?

A- In order to make the acceleration performance of the vehicle better;

B- If you step on the accelerator too deeply, the automatic transmission has limited response and acceleration performance. If you step on the accelerator by 20%~40%, the upshift will be faster;

Transmission controller, in order to improve the acceleration performance of the vehicle, try to accelerate with low gear, so that the vehicle will speed up faster.

Generally speaking, there are three types of vehicle training:

1, biased towards dynamic performance, so there are more cases of low gear and high speed, the car is faster, but the fuel consumption is obviously higher;

2. Intermediate type with comprehensive consideration of power and fuel economy, giving consideration to both power and fuel economy. Similarly, power performance and fuel economy are not the best;

3. In favor of fuel economy, the transmission upshifts faster, and generally upshifts when the working speed of the engine is relatively low, and the fuel economy is better, but the speed is obviously slower.
