Compared with the manual transmission car, the automatic transmission gearbox eliminates the need for a clutch pedal, and the pedal is not frequently needed to make the driving of the vehicle simple and easy。 That's where the people are。 The correct use of automatic transmission, but also reduce fuel consumption, reduce pollution, avoid or reduce the occurrence of failures。 On the contrary, it will increase the failure rate of the automatic transmission and reduce the service life。
1, start and start
When starting the automatic gearbox, the automobile engine, must choose the gear control handle in the P gear or the N gear, and tightens the hand brake. When you start the car should first step on the brake pedal, hang up, loosen the hand brake, and then steadily lift the brake pedal, the car began to slow down and then gradually stepped on the accelerator pedal. Should also pay attention to the car started: after starting the engine, the car started before, do not step on the accelerator pedal; the gear, do not loosen the brake pedal; after the start, do not step on the accelerator pedal too fast, too, should be slowly down.
Road driving, can choose to block the handle is placed in the D gear, according to the size and speed of the vehicle throttle level to automatically change gear, not as long as the D block starts has been increasing the solar term door opening up into high gear"。 The correct operation is to achieve a certain value after the speed, so that the throttle in advance to lift the block, step on the throttle ahead of the block"。
The general small ramp can be in the D position with the accelerator pedal and brake pedal to control the car, downhill speed。 In case of a long steep slope, should be selected from the D gear control block displacement to S or L gear block (depending on the slope)。 This can be avoided in D gear uphill, automatic gearbox "cycle jump stop caused by insufficient power。" (continuous reduction gear, and gear), increasing the automatic transmission shift actuator wear, and downhill, in S or L gear gear under the engine can use the idle speed control to pull production。 Muddy road at this time, should be selected from the D block control handle to the S gear block or L block。 For the automatic transmission with the driving mode selection key, the driving mode can be changed according to the road condition, and then the manual transmission is changed into the appropriate gear。
When the need to overtake, the opening of the throttle will increase rapidly, then the automatic transmission will automatically reduce a gear, the power of the vehicle to enhance, can get a strong acceleration effect. To be accelerated to meet the requirements, should immediately release the accelerator pedal (automatic transmission and automatic into high gear), in order to avoid the engine speed is too high and the high gear shift actuators cause excessive impact. If driving, overtaking emergency situation, try not to be quickly stepped on the accelerator pedal in the end, because this kind of automatic transmission will be "forced low gear" control, automatic gearbox immediately forced to switch into low gear to make the engine speed is too high, causing friction wear and automatic gearbox oil temperature automatic gearbox in.
In addition, equipped with automatic transmission car, do not use the N gear taxiing, otherwise, not only easy to make automatic transmission oil temperature is too high to affect its service life, but also caused by the high-speed rotation of the gear is not sufficient lubrication and ablation.
