Passing requirements: pour into the bottom of library B from the starting point and stop, then move into library A and stop. Then go straight through garage B and stop on the road, and then go back to the middle of garage A and stop. Finally, the goods are delivered from warehouse A to the starting point.
Coach instruction: The coach will set three signs at the rear edge of the carriage, including a middle punctuation mark at the edge of the carriage and two punctuation marks at both sides of the edge of the carriage (hereinafter referred to as left punctuation mark and right punctuation mark). These punctuation marks were set by the coach after summing up his experience in the teaching process. According to different models, the position of punctuation marks is different. When the sheet piling platform is reversed, use reverse gear to drive the vehicle straight backward. When the driver sees the front center bar from the right frame of the right rear door window, he can turn the steering wheel to the right twice. Then, wait for the vehicle to pour into the pile. When the rear of the car gradually piles up, keep your eyes on the punctuation mark on the left side of the rear. When the left punctuation mark is aligned with the rear middle bar, immediately turn the steering wheel to the left twice, that is, turn the steering wheel forward. After the vehicle enters the pile, adjust the steering wheel at any time to ensure that the midpoint of the rear of the vehicle is between the last two poles in the pile, so that the vehicle can keep driving in a straight line.
Learning process: moving piles to the library is the bulk of the operation examination, so the training time accounts for more than two-thirds of the total training time. Students in double-off classes spend all their training time in the evening, and it is not easy to practice well. At first, the reporter followed the coach's request. Either the back of the car hit the front center bar or the side bar, and he always couldn't get into the pile. Sometimes, when you get into the pile, you won't adjust your direction. The vehicle bends in the pile, or the vehicle is pushed out of the pile.
Learning experience: After 10 days of hard training, the reporter has a little insight. In the coach's words, he will adjust flexibly. When starting to dump the sheet piling platform, always pay attention to the distance between the right rear corner of the carriage and the front center pole. If you hit the right direction too early, the vehicle will easily hit the front middle bar. In this case, turn left in time, that is, pull the car away from the middle bar in front, and then wait for the left punctuation to aim at the middle bar behind. If you complete the direction, the vehicle can easily hit the side rail. In this case, no matter how to adjust the direction, the vehicle will not enter the pile. Therefore, it is better to reverse the direction sooner rather than later.
Passing requirements: small cars use first speed and ride 6 pressure? s？ When the round cakes placed on the track pass by, the wheels and rails shall not touch, rub or crush the round cakes, and shall not exceed or crush the edge lines on both sides.
Instructor's guidance: Before passing the first two cakes, when the driver feels that he is at the midpoint of the two cakes, he should adjust the direction and keep the vehicle running straight. Visually, you can turn left when the front edge of the carriage is flush with the front edge of the third round cake. When the driver feels that he is in the center line of the third round cake, he can turn right. The principle of turning back is that there are as many directions for turning right as for turning left. The riding mode of the fourth, fifth and sixth rounds of cakes is the same as that of the third round of cakes.
Learning process: The first three round cakes are relatively easy to pass. When passing the round cake behind, the reporter is always in a hurry at first, and often rolls over the round cake.
Learning: Passing through continuous obstacles is mainly to test the driver's ability to judge the track of each wheel and the position of inner wheel difference. When six round cakes are covered. ; s？ Trajectory, starting from the second pie, the vehicle should hit the direction, and the vehicle should also press? ; s？ Field driving. After repeated training, the reporter found that due to the problem of the driving route of the vehicle, after passing the fourth round cake, it is necessary to speed up the hitting speed and correct the direction in time, otherwise it will hit the round cake.
Passing requirements: To correctly grasp the direction, respectively, use the left and right wheels to crush the two bridges A and B under the wheels to pass smoothly.
Coach notes: Before passing through unilateral bridge, the coach will set two marking points on the hood. Set the left punctuation mark on the edge line of the left cover. When crossing the bridge, the left punctuation mark is on the same line as the left bridge centerline. Set a right punctuation mark near the midpoint of the front edge of the hood. Turn right after crossing the left bridge, wait until the right punctuation coincides with the line outside the right bridge, keep the direction unchanged, and let the right wheel get on the right bridge. After the right wheel starts to get on the right axle, turn left and keep the vehicle running straight.
