Description

The invention relates to automatic control systems and can be used in simulators for training drivers of vehicles. The purpose of the invention is to increase the accuracy of the device with improved modeling of the work of the tracking system. The drawing shows the structure of the device. The device contains a speed sensor 1 (rectilinear motion), a block 2 for entering educational information (reading topograms), multipliers 3 and A, adder 5, rectifier 6, integrator 7 driver 8 absolute signal magnitude, integrator 9, inverter 10, multiplier 11 calculator 12, inverter 13, an amplitude limiter 14 on a yarn, an adder 15, a control sensor 16, a soil type sensor 17, a steering machine 18, a control organs 19, a projector 20, an operator 21, a screen 22, an operator response input unit 23 and a unit 24 presentations in laziness of educational information. The device for controlling the film simulator operates as follows. From block 2, the voltage is removed proportional to the curvature of the track. The latter is multiplied by a multiplier 3 by a voltage proportional to the speed of the rectilinear movement taken from sensor 1, which is either a potentiometer or a device for simulating driving dynamics. At the output of the multiplier 3, a voltage U, proportional to the angular velocity of the road relative to the machine, is formed. From calculator 12, which converts the actions of operator 21 to angular velocity, the voltage U "is proportional to the angular velocity of rotation of the machine. This voltage is fed to the input of the adder 5. The voltage appears at the output of the latter: proportional to the difference Uo, which characterizes the presence of the angular velocity of the machine relative to the route. The latter is transformed by the integrator 9, t, e, a voltage is formed that is proportional to the angle of deviation of the machine from the track. After multiplying this voltage by a factor 11 on the output voltage of the sensor 1, a voltage is generated that is proportional to the speed of the deviation of the machine from a predetermined motion path. The latter with the help of the adder 15 is summed with a voltage proportional to the angular velocity of the machine relative to the route coming from the output of the adder 4. Thus, at the output of the adder 15, a voltage is generated, which with the help of the machine 18 turns ki; the projector aside, imitating the exit of the highway. The adder 15 in the presence of a drift also enters the voltage Uy. proportional to the lateral slip of the machine, which is opposite to the value of Ufj given on the inputs of the adder 15, thereby reducing the voltage and, t. In the simulator, it looks as follows. The driver drives the car in the photo, the image of which he sees on the screen. If a turn appears on the screen, the driver squeezes the corresponding turn lever. If this does not cause skidding, Up.p 0 and U (UQ, Then the voltage at the output of the adder, 15 is zero and the film projector does not rotate. This creates the illusion of turning the turn along a predetermined trajectory. If during rotation a skid occurs, then , "Oh, and in the same situation, the film projector turns in the direction of rotation, which creates the illusion of an exit (skidding) from the road. A voltage is formed, based on the following equation:. (" .Y, .p ,,,,) where Vg - lateral slip speed; q is the acceleration of gravity; m is the mass of the machine, t is the angular velocity of rotation ota machine} V - linear velocity of the machine, the rotation resistance coefficient characterizing clutch caterpillars with the ground in the transverse direction is formed product by using the multiplier 4 and to the input of the integrator 7, with which the equation is solved at..

two opposite vertices of straightener 6, the voltage U ,, comes,

(UMOKC

and on the anodes of diodes +1.,, on the cathodes of diodes -i. Such a connection is necessary in order for the integrator not to be charged by the voltage "max. The voltage U is supplied from the sensor 17 (it can be either a potentiometer or a switch, or a reading device from the information carrier). An invert 13 serves to create a multipole voltage on a bridge gate.

With this method of determining U, a situation is possible when Uy is greater than U (. In this case, the image begins to move in the opposite direction. This is possible if the driver, despite moving off the track, continues to squeeze the lever towards himself. a limiter 14 is introduced, by which the condition Uygc 6 Ujj is fulfilled. For this, the voltage ± U (j is applied to the control inputs of the limiter 14. An inverter 10 is used to create a different polarity, and the voltage module UQ is formed using a driver 8. So In this way, the proposed device allows for more accurate reproduction of the rotation of the machine on a cinema simulator, as a result of which the quality of driver training is improved.
