Examination sequence of subject 2:
Right-angle turn
Operation essentials
① The car starts with a low gear.
② Before the car enters the right corner, drive on the right side, and the distance between the right wheel and the right side line of the road is about .1m.
③ When the car reaches the point where the driver is aligned with the inner right corner, quickly turn the steering wheel to the limit position.
(4) When the left rear wheel crosses the protruding point of the inner right angle, it starts to drive out of the road in the right direction gradually.
⑤ straighten the car and drive out of the road.
operation skills
① pass at idle speed in the first gear, and don't refuel.
② Before entering the right-angle bend, keep the car as far away from the protruding point as possible in the two sides of the road.
③ when the center of the small triangular window on the front window near the protruding point coincides with the protruding point, turn the steering wheel to the side of the protruding point to the end. When the front of the car turns to a new direction, pay special attention to the right front wheel not to press on the right side of the road.
④ try to stick to the right side line when turning at right angles.
⑤ when you see the front of the car aiming at the exit, you will quickly return to the right direction.
⑥ Pay attention to the inner wheel difference, correctly estimate the track of the inner rear wheel, and do not press the protruding point and sideline of the inner right angle, and do not stop or reverse.
curve driving
operation essentials
① Before entering the "S"-shaped road, reduce the speed, use the first or second gear to enter the "S"-shaped road, and choose the appropriate route and speed to pass.
② after entering the "s"-shaped road, the vehicle enters the curve along the right side of the road (about 1m away from the edge of the left side road) and keeps a uniform low speed.
③ when entering the position of point a, keep the distance between the vehicle and the right side of the road about .5m, and correct the direction appropriately (leave enough distance for the left inner wheel difference).
④ enter the position of point c, turn the steering wheel to the left, and the vehicle will drive from the right side to the left side.
⑤ enter the second corner, keep the left wheel of the vehicle .5m away from the curb line, and correct the direction appropriately.
⑥ enter the position of point f, turn the steering wheel and drive in a straight line.
operation skills
① keep driving in the first gear all the way, and don't drive too fast.
② Try to make a big circle after entering the curve. When driving to the right curve, the right wheel will cling to the edge line of the right road, and vice versa.
③ when in a curve, the small rearview mirror on the inner hood of the car is always at the edge of the outer white line through the steering wheel, so that it can neither go out nor be too far away from the edge line.
④ adjust the direction in time according to the characteristics of the road bend and the radius of the rear wheel.
Side parking
Operation essentials
① The car starts with low gear. When the driver is aligned with point ③, turn the steering wheel to the right.
② When the car travels to the middle position where the front of the car is located at points ③ and ④, quickly turn the steering wheel to the left to make the front of the car turn to the left of the road.
③ when the front of the car approaches the left side line of the road, turn the steering wheel quickly and stop immediately.
(4) put the car in reverse gear and reverse it. When the rear of the car approaches the right sideline of the parking space (garage), quickly turn the steering wheel to the left to the limit position.
⑤ when both sides of the car body are parallel to the parking space (garage) sideline, quickly correct the steering wheel and stop.
Operation skills
① Sit upright, which plays a key role in judging the accuracy of each point.
② drive into the parking area and park on the right side of the road as far as possible, but don't press the yellow right edge line, so as not to back up too far and press the line!
stop and start at a fixed point on the ramp
operating essentials
1. Stop at a fixed point on the ramp
① After hearing the instruction of "stop at a fixed point on the uphill" (about 2 meters away from the pile pole), turn on the right turn signal and turn the steering wheel to the right appropriately, so that the vehicle can drive slowly on the right side of the road, and pay attention to the distance between the vehicle body and the right side line.
② when the vehicle is driving about 1m near the parking post, it will approach the positioning target slowly, accurately and smoothly.
③ Visually observe the target accurately, and aim at a certain point on the parking pole, windshield (or hood) (this point should be determined in practice due to different vehicle models and drivers' heights). When it is visually observed that a certain point of the windshield is in a straight line with the parking pile pole, that is, the vehicle bumper is aligned with the parking pile pole line, stop immediately.
2. Start on the ramp
① First step on the clutch pedal, shift to low gear, turn on the left turn signal and sound the horn to indicate that the vehicle is about to start.
② press the accelerator pedal to increase the engine speed, and at the same time lift the clutch pedal to semi-linkage (it can be judged from the engine sound that when the clutch pedal is lifted, if the engine sound becomes dull, it proves that the clutch is in semi-linkage).
③ Slowly release the parking brake lever, and slowly press the accelerator pedal, while continuing to slowly lift the clutch pedal.
④ when the clutch is fully engaged, continue to press the accelerator pedal to make the vehicle start smoothly.
operating skills
1. Control the speed
When parking at a fixed point on the ramp, the speed should be slightly faster before going uphill, so that the car has a little momentum, otherwise it will not be able to go uphill. After the rear wheel goes uphill, the speed should be reduced immediately to make the car drive slowly. Otherwise, if the speed is too fast, it is too late to adjust the relative position between the car and the sideline; Second, it is too late to stop at the reference point.
2, to choose a good reference point
① If you want to keep a proper distance between the car body and the right line, you must know the position of the right front wheel. Because the driver can't see the right front wheel in the car, he can only find a certain point in the car for reference. For an ordinary Santana car, generally speaking, after sitting in the seat, the ground seen from the center of the front of the car is probably where the left edge of the right wheel is about to arrive. Some cars have a trademark ornament in the center of the car head, and the root of this ornament just marks the center of the car head. But most cars don't have this ornament on the front of the car. You can stick a piece of colored tape or tape paper in the middle of the front of the car first, and then tear it off after you are proficient. Alternatively, you can choose a reference point at the appropriate position of the wiper and use it instead of the point in the middle of the car. In general, there is a bend on the wiper swing lever. The highest point of the bend on the left wiper is just on the line between the eyes and the center point of the front of the car. The ground seen from the highest point of the bend is the left edge of the right wheel.
② reference point of front bumper If the bumper is just aligned with the post after parking, it is necessary to find the reference point. This reference point is generally at the first section on the left side of the right wiper, that is, the driver sees that the first section on the left side of the right wiper is aligned with the stake, and then stops at this time, and the position is just right.
It's worth noting that people are different in figure, and the seats are different in front and back, so there is always deviation. In addition, even cars of the same model have different parts specifications due to different production years, batches, manufacturers, or other special reasons, so it is impossible to mechanically copy the dogma, and it should be determined according to the actual situation.
3. Actions should be coordinated
When starting on a ramp, the clutch, accelerator pedal and parking brake lever should be coordinated, and the timing of releasing the parking brake lever is critical. If the car fails to start late, the engine will stall; If you are early, you will slip back. This timing is the skill to be mastered when the clutch pedal is lifted to semi-linkage: First, listen to the engine sound; The second is to feel the body shaking; The third is to watch the tachometer pointer tremble and move down.
Parking in reverse
Operation essentials
1) Pour into the garage from the starting point
① After getting on the bus, the driver should adjust the seat and rearview mirror, fasten the seat belt, then put the car into reverse gear, release the parking brake lever, and then back at idle speed after auto start. The driver can observe the garage through the right rear window.
② When you see that the black edge of the right rear window is aligned with the right thread of the garage, turn the steering wheel to the limit position at a uniform speed to the right, as shown in Figure 4-3.
③ After the car is put into storage, the driver looks back at the left rearview mirror and straightens the steering wheel immediately when he sees the left sideline of the whole garage.
④ stop immediately when you see from the left rearview mirror that the left door handle is level with the bottom line of the garage, as shown in figure 4-5.
2) Drive into the carriage return point from the garage
Drive out of the garage before shifting into 1st gear. When you see the hood approaching the road sideline (Figure 4-6), turn the steering wheel to the limit position to the left, and stop after the car is straight.
3) Pour into the garage from the return point
① Put the car in reverse gear, keep the limit position of the steering wheel left unchanged, and reverse the car backwards.
② The driver should pay attention to the left rearview mirror and correct the direction, so that the rear of the car can be dumped into the garage.
③ After the car is put into storage, the driver should pay attention to the right rearview mirror, and immediately straighten the steering wheel when he sees the right line of the whole garage.
④ The driver turns his eyes to the left rearview mirror and stops immediately when he sees that the left door handle is level with the bottom line of the garage.
4) Drive into the starting point from the garage
Drive out of the garage before shifting into 1st gear. When you see the hood approaching the road sideline, turn the steering wheel to the limit position to the right, and stop after the car is straight.
operation skills
① control the driving speed, and idle in 1st or reverse gear all the time, and drive at whatever speed you start.
② control the steering timing, and carefully observe the steering process, grasp the key points of steering, and turn in time.
③ When controlling the driving route, the driving route of the car mainly depends on the speed of turning the steering wheel and the driving speed. When reversing, it is necessary to look at the sideline and correct the direction in time to keep the car upright in storage.
