Abstract

The invention relates to vehicle driving aids and can be used to teach how to drive a vehicle when it is sideways and to decrease stability on slippery roads. The purpose of the invention is to increase the effectiveness of training. On the carriageway of road 3, front 1 and rear 2 platforms, which are movable in the lateral direction, are connected in series with power cylinders 7 and 8 connected by control unit 6. Off-road position sensor 4 is installed. At the entrance of the vehicle 5 to the platforms, the latter are moved in the lateral direction, imitating the movement with a side skid. The learner seeks to enter the vehicle in a given corridor. 2 Il.

learning. On the carriageway of road 3, front 1 and rear 2 platforms, which are movable in the lateral direction, are connected in series with power cylinders 7 and 8 connected to control unit 6. Outside the carriageway, a position sensor 4 is installed. When the vehicle 5 arrives at the platforms, the latter are moved in the lateral direction, simulating a movement with a side skid.

The invention relates to technical means of teaching driving a vehicle and can be used to teach how to control a vehicle when it is sideways and to decrease stability on slippery roads.

The purpose of the invention is to increase the effectiveness of learning.

Fig.1 shows the general scheme of the simulator; 2, a block diagram of the control unit.

The dynamic simulator contains front 1 and rear 2 horizontal platforms movable in the lateral direction. The sensor 4 is mounted on the carriageway. Outside the roadway, sensor 4 is fixed, interacting with the vehicle 5 as it moves 1: Rei 1 and rear 2 horizontal ILIO- to the bridges and connected to the input of the control unit 6. The front 1 and rear 2 horizontal platforms are connected with lateral movement leads, which include power cylinders 7 and 8, cavities 9,10 and 11,12 of which are equipped with electro-controlled hydraulic distributors 13 and 14 with electromagnets connected to the outputs of the control unit 6 The input lines of electrically controlled hydraulic distributors 13 and 14 are connected to a pressure source 15 containing a hydraulic pump 16, a hydraulic accumulator 17, a safety valve 18, a check valve 19 and a tank 20

The control unit 6 contains sequentially connected information input device 21 connected to position 4 sensor, central microprocessor 22 with random program memory device 23, digital-to-analog converters 24 and channel power amplifiers 25 connected to electromagnets of hydrodistributors 13 and 14. On the carriageway 3 mouth

plastic posts 26 are shown indicating a wide range of movement.

The dynamic simulator works as follows.

In the initial position, the front 1 and rear 2 horizontal platforms ({are fixed by power hydraulic cylinders 7 and 8 in the middle position in the middle zone of the carriageway 3, When the vehicle 5 moves on road 3 and the front wheels hit the rear horizontal platform 2, and the rear the wheels on the front horizontal platform I, the position sensor 4, provides a signal in the form of a constant voltage to the input of the information input device 21 of the control unit 6, where this signal is level calibrated and encoded.

With this signal from the program memory unit 23, a command is sent to the microprocessor 22, which generates control signals, which in the form of a code are fed to the corresponding digital-to-analog converter 24, take an analog form, are amplified using power channel amplifiers 25 and as voltages are transmitted to electromagnets of hydraulic distributors 13 and 14, which direct the flow of fluid into the corresponding cavities of the power hydraulic cylinders 7 and 8,

Depending on the sequence and combination of U-U signals, the hydraulic distributors 13 and 14 can capture three positions: shut off the flow of fluid in cavities 9 and 10 of the power cylinders 7 and 8, deliver fluid to cavities 9 and 11 or 10 and 12. The pistons the power cylinders 7 and 8 move and carry out a rapid displacement of the associated front 1 and rear 2 horizontal platforms in the lateral direction relative to the direction of movement of the vehicle 5, for example, while simultaneously applying pressure in the polo 10 and 11 and connecting the cavities 9 and 12 with a drain, the front horizontal platform 1 moves to the left and the rear horizontal platform 2 moves to the right, the tire front and them and the rear wheels of the vehicle 5 with platforms 1 and 2 lead to a side skid. vehicle 5. The trainee, the control vehicle 5, tries to enter it in a predetermined movement corridor A width indicated by 26o plastic columns. If the student does not introduce vehicle 5 into the predetermined corridor width A, the race is repeated. Depending on the direction and sequence of movement of the pistons of the power cylinders 7 and 8, various combinations of movements of the front 1 and rear 2 horizontal platforms are provided. Thus, in the proposed dynamic simulator, the conditions of the vehicle movement are simulated

with a side skid, which increases the efficiency of training in driving a vehicle.
