When driving, whether it is automatic or manual, old drivers are accustomed to "stepping on and loosening", while some novice drivers do not have such habits, seemingly inadvertent driving habits, over time, you will find that there is a clear gap between the two, and even key moments can "save life".
In fact, for manual transmission models, stepping on and loosening is generally the normal operation of shifting gears, but many old drivers driving automatic transmission models still have such operating habits, in summary, such operations have at least 4 benefits.
First, defensive driving, using the throttle to control the speed of the vehicle, helps to drive safely.
I have been driving for more than ten years, usually driving around the city, the road conditions are relatively complicated, step on the accelerator, when the speed can no longer be faster, at this time will release the accelerator, let the speed slowly drop a little, if you see the front brake light on, at this time will subconsciously put the right foot on the brake, ready to brake at any time.
That is, we often say "stepping on the brake obliquely step on the accelerator", the right foot heel does not move, when you need to step on the accelerator, the right foot tilts to the right to step on the accelerator, do not need to step on the accelerator, the right foot quickly returns to the brake side, virtual on the brake, slowly form muscle memory, if you encounter an emergency, the first time to step down may also be the brake instead of the accelerator, even if you step on the wrong step, you can immediately correct, the sole of the foot to the left step down is the brake.
For example, after passing through the traffic light intersection, there are large trucks, buses, walls, etc. on both sides to block the line of sight, at this time, after stepping on the accelerator, you will soon release the accelerator, quickly put your right foot on the brake, let the vehicle slow down, rely on inertia to drive, if you encounter pedestrians on both sides, non-motor vehicles crossing the road, you can also prevent this "ghost probe" in the first time.
Second, the use of "taxiing strategy" can save 1-2 liters of oil per 100 kilometers.
For example, if you see the green light from a distance for 2-3 seconds, the novice driver may still step on the accelerator, seeing that it is about to reach the intersection, only then release the accelerator, and slow down by braking, for the old driver, it is estimated that it has been unable to pass, and the accelerator will be released in the appropriate position, allowing the vehicle to slide to the traffic light intersection.
If you see the red light from a distance with only a few seconds left, the green light will be on, at this time you can also predict by the speed of the car, release the accelerator when you are in the appropriate position, and just green light when you are about to reach the intersection, at this time the vehicle does not stop completely, and then lightly step on the accelerator to pass, fuel saving This is undoubted.
Similarly, go up the bridge, climb a small steep slope and go downhill, step on the accelerator in advance to accelerate, and when you are about to reach the top of the slope, directly release the accelerator, pass the inertia to the top of the slope, and you do not need to immediately press the brakes when going downhill. The same is true when passing corners, releasing the throttle in advance and then lightly pressing the accelerator to accelerate after cornering.
When running at high speed, when the speed reaches 120 km / h, you can release the accelerator at this time, use inertia to drive a distance, and then lightly step on the accelerator to accelerate, but here you need to pay attention to the need to master the timing to save fuel, almost reduce the speed to about 110 to lightly step on the accelerator to accelerate. If you release the accelerator, the speed drops below 100 and then step on the accelerator to accelerate, which will increase fuel consumption.
In the daily driving process, through these small driving habits, the average 100 kilometers can save at least 1-2 liters of fuel, which is why driving a car, some novice drivers will always drive much higher fuel consumption than old drivers.
Third, automatic transmission models are conducive to controlling the best gear.
For automatic transmission models, intelligence is getting higher and higher, and the driving computer is mainly based on the size of our accelerator, the current gear, the speed, and the speed of the information for intelligent upshifting. The basic logic of the automatic transmission is that the larger the throttle is pressed, the greater the need for acceleration.
In order to get better power, at this time the gearbox will delay the upshift, for example, you step on the throttle by about 10%, at this time the engine speed may be upgraded to 2000 rpm, but if you directly step on the accelerator, the throttle opening is 30%, at this time the ECU may judge that you need more torque, so delay to 3000 rpm to upshift, but waste fuel consumption.
Therefore, for automatic transmission models, when starting or driving at low speed, you need to speed up, at this time do not step on the accelerator, after lightly stepping on the accelerator, release the accelerator, and then lightly step on the accelerator again, so that it will quickly upshift and save fuel.
Fourth, it is conducive to the relaxation and rest of the right foot, and it will not be too tired after driving for a long time.
Long-distance driving, if we step on the accelerator for a long time, the right foot is easy to fatigue for a long time, after stepping on the accelerator to increase the speed of the car, you can release the accelerator, use the vehicle inertia to drive a distance and then accelerate, so that the cycle is repeated, not only can save fuel, but also relieve the fatigue of the right foot.
In short, when driving, "one step and one loose", also called "hanging the accelerator to go", either an old driver, or a novice, to really achieve fuel saving, safety, which requires high experience of the driver, only to practice the "golden right foot" technology, can save fuel, otherwise it will only increase fuel consumption, but also may lead to dissatisfaction with the rear car.
