Abstract

The invention provides an auxiliary observation method for the wheel of a coach car, which relates to the field of auxiliary teaching of the coach car, especially the aspect of sensory recognition of the wheel position of the coach car. When practicing unilateral bridges, continuous obstacles, and curved roads, it is necessary to control the position of the wheels. The technical solution of the present invention is: a camera is installed at the bottom of the rear of the car, and the image information collected by the camera is transmitted to the monitoring equipment near the steering wheel; in order to avoid the failure of the camera caused by mud, the camera is sealed in a waterproof sleeve, and there is a Plastic light-transmitting sheet; the camera is installed in the middle of the bottom of the rear of the car, and the position is suitable for seeing the front and rear wheels. According to the teaching of the coach, the trainees can quickly establish their own sense of space by comprehensively observing the positions of the wheels, seats and the front of the car; improve the teaching effect and improve the teaching efficiency of the driving school.

Description

Auxiliary Observation Method of Trainer Car Wheels

technical field

The invention relates to the field of auxiliary teaching of a coach car, in particular to the sensory recognition of the wheel position of the coach car.

Background technique

Now the coach car is practicing unilateral bridges, continuous obstacles, and curved roads. There is control over the position of the wheels. In order to cope with the exam, what the coach teaches is to look at the front, window, rearview mirror and other signs, but the height and the front and rear of the seat are different. , the observation results will also be different, and it is impossible for the coach to guard the students all the time, which makes it difficult for some students to learn to drive.

Contents of the invention

In order to overcome the trainees' inflexible memory of the coach's teaching, the present invention uses a monitoring system to observe the position of the wheels to self-improve the ability to control the wheels.

The technical solution adopted by the present invention to solve the technical problem is: a camera is installed at the bottom of the rear of the car, and the image information collected by the camera is transmitted to the monitoring equipment near the steering wheel. There is usually a lot of dust or mud on the bottom of the car. In order to avoid the camera failure caused by the mud, a waterproof sleeve is used to seal the camera inside. There is a plastic light-transmitting sheet in front of the sleeve. When you can’t see clearly, rinse with water or wipe the light-transmitting sheet with a wet towel. This camera system is to observe the relative position of the wheel and the road surface, and does not need particularly clear details. The camera is installed in the middle of the bottom of the rear of the car, and the position is suitable for seeing the front and rear wheels.

The beneficial effects of the present invention are: the trainees can quickly establish their own space perception system according to the coach's teaching and comprehensively observed wheel position, seat position and the position of the front; The relationship between them, constantly correct their own judgment, and quickly master the accurate control of the wheels; through the camera system to assist in observing the wheels, students can more quickly master the skills of unilateral bridges, continuous obstacles, and curved roads; improve the teaching effect and improve the teaching of driving schools efficiency.

Description of drawings

Fig. 1 is a schematic diagram of the cameras arranged in the auxiliary observation method of the trainer vehicle wheels.

Among them, 1. student, 2. trunk lid, 3. camera.

Detailed ways

Adhere the base of the camera 3 to the vertical surface of the trunk lid 2 of the coach car through magnets. The horizontal position is in the center of the car body. A bendable connecting rod is placed on the base. The camera 3 is placed on the connecting rod, and the connecting rod is bent , so that the camera 3 is 20cm away from the ground and roughly parallel to the ground, so that the front and rear wheels of the car can be observed.

There will be a lot of dust or mud splashing from the bottom of the car. In order to prevent the camera from being invalid due to dirt, a waterproof sleeve is used to seal the camera inside. There is a light-transmitting sheet in front of the sleeve to prevent small stones from splashing from damaging the light The back of the film will damage the camera. Avoid using glass for the light-transmitting film. It is best to use transparent plastic. To enhance its strength, you can add a wire grid in front of the plastic film. The wire diameter is 0.2mm and the interval is 1mm. The back of the light-transmitting film is next to the camera , When the information transmitted by the camera cannot be seen clearly, rinse with water or wipe the light-transmitting sheet with a wet towel. This camera system is to observe the relative position of the wheel and the road surface, and does not need particularly clear details.

Student 1 sitting in the driver's cab corrects his sensory knowledge based on his own observation and referring to the wheel position information transmitted by the camera. After many times of practice and correction, the student can position the wheel according to his intuitive feeling of the car body. location.

Claims (1)

1. the auxiliary observation method of the coach car wheel of the present invention is characterized in that: a camera is installed at the bottom of the rear of the car, the horizontal position of the camera is in the center of the car body, and the vertical position is 20cm away from the ground; the image information collected by the camera is transmitted to the monitoring near the steering wheel Equipment; a waterproof sleeve is used to seal the camera inside, and there is a plastic light-transmitting sheet in front of the sleeve, and the camera is adjacent to the light-transmitting sheet.
