How should the automatic gear car climb the hill? Only novices will hang up D gear to step on the accelerator, old drivers are using this trick, with the development of society, the pace of our life is getting faster and faster, slowly becoming a habit of faster, more convenient way of life, for cars, domestic automatic cars are more popular than manual transmission, mainly convenient to operate, and not much more expensive, for those female drivers also save a lot of trouble.
However, many drivers are driving automatic cars, whether it is starting from the flat ground, or uphill, downhill only know "1D to the end", of course, in the case of short slopes, generally use D gears have no problem, but when encountering sharp and long slopes, if you use D gears to go halfway, the power is often not able to catch up.
First of all, when the automatic cut off of the car uphill, the driving computer will issue instructions according to the driving state to upgrade and downgrade, but due to the particularity of the ramp, the vehicle will frequently replace the displacement in the process of going uphill, the power output is not smooth, it is easy to accumulate carbon, therefore, we hope to use M, L or S to maintain a higher number of rotations of the engine, maintain a large torque output, the uphill is more labor-saving, more stable, it should be noted that close to the top of the ramp, control the speed of the car, the field of vision is limited, the speed of the car is too fast, easy to occur danger.
In addition, downhill D-type brakes have not been able to use, brake discs are easy to overheat, brake performance declines, sometimes brake failure, of course, can not directly use the N-type barrier, such behavior is very dangerous, vehicle fire extinguishing, brakes and steering are likely to lose effect, so downhill use of L-type gear is the most appropriate, limit low gear, with the engine can achieve the purpose of deceleration braking.
If your car only has S gear or M gear, you can use S gear when going uphill, you can use D gear downhill, this model has been adjusted to the up and down long slope, so you can no longer use S gear to stop downhill, this is a sports gear, can only be used when going uphill, only M-type gear models, you can reduce the speed by downshifting, you can also get the effect of L-type gear, although the car is bought to open, not supplied, but after choosing the right gear, it is still worry-free and labor-saving.
