[驾驶知识]Points to note when driving an automatic car

automatictransmissioncarCompared with manual transmission cars, it savesClutch pedal, No need to step on the pedal frequently, making car driving simple and easy. This is what people love. The correct use of automatic transmissions can also reduce fuel consumption, reduce pollution, and avoid or reduce the occurrence of failures. On the contrary, it will artificially increase the failure rate of the automatic transmission and reduce its service life.
Starting and starting When starting the automatic transmission car engine, the gear selector must be placed in the P gear or N gear, and the hand brake must be tightened or stepped onBrake pedal. When the car starts, step on the brake pedal first, after gearing, release the hand brake, then steadily raise the brake pedal, and then gradually step on the accelerator pedal after the car starts slowly. When the car starts, you should also pay attention: after the engine starts and before the car starts, do not step on the accelerator pedal; when in gear, do not release the brake pedal; after starting, do not step on the accelerator pedal too fast, but slowly .
When driving on a flat road, the gear selector can be placed in the D position, and the gear can be automatically changed according to the throttle and the speed of the vehicle. It is not "as long as the D gear starts to increaseThrottleThe opening degree can be raised to high gear." The correct operation is to "remove the accelerator to advance the gear and step on the accelerator to downshift" after the vehicle speed reaches a certain value.
When driving on a general small slope, you can use the accelerator pedal and the brake pedal to control the up and downhill speed of the car in the D gear. In case of a long steep slope, shift the gear selection joystick from D gear to S gear or L gear (depending on the slope). This can avoid the automatic transmission "cycle skipping" (continuous downshifting and upshifting) due to insufficient power in the high gear when going uphill in the D gear, which will aggravate the wear of the automatic transmission shifting actuators and go downhill. When in S gear or L gear, the idle speed of the engine can be used to control the vehicle speed.
At this time on muddy roads, shift the gear selection joystick from D gear to S gear or L gear. For automatic transmissions with a driving mode selection button, the driving mode can also be changed according to the road conditions, and then the driving mode can be manually shifted to the appropriate gear.
Overtaking When it is necessary to overtake, quickly saveValveWhen the opening degree of the car is increased, the automatic transmission will automatically lower a gear, and the car’s dynamics will be enhanced and a strong acceleration effect can be obtained.After the acceleration meets the requirements, the accelerator pedal should be released immediately (the automatic transmission automatically rises to high gear) to avoid engine damage.Rotating speedToo high and cause excessive impact on high gear shifting actuators. During driving, if it is not an emergency overtaking situation, try not to depress the accelerator pedal quickly, because in this way the automatic transmission will carry out "forced low gear" control, that is, the automatic transmission will be forced into low gear immediately, which will easily cause the engine speed to be too high, causing The friction lining wear in the automatic transmission is increased and the temperature of the automatic transmission oil is too high.
