    2. The device according to claim 1, characterized in that the transmission control system includes a microcomputer with an action program and a progia system program, and the device is equipped with an instantaneous speed sensor and an engine load connected to the inputs of said microcomputer, whose outputs are connected to the switch shift control devices.
    The invention relates to a device for controlling a manual transmission with automatic gear shifting and an electronic control system, especially for manual transmissions of automobiles. Control or command systems are known that operate on the principle of determining the speed of movement and load of a car by the revolutions of the output shaft of the gearbox and by the position of the fuel supply control body. After reaching the preset parameters, they issue a command to switch the mechanical steps. A disadvantage of the known systems is that with increased resistance to movement, cyclic switching of the corresponding gears takes place. This phenomenon is caused by the fact that when driving in a lower gear, the car receives acceleration to a value corresponding to shifting to a higher gear, but a higher gear causes a lower traction force, which, under certain resistances to movement, can cause a slowdown in the motion of the car, i.e. shifting to a lower gear occurs before a change in resistance to movement, usually before a set of lifting, i.e. there is a forced switch to the lowest gear level. The frequency of cycles is higher as the hysteresis of switching from higher to lower gears is smaller, and increasing the hysteresis, on the contrary, complicates the choice of the optimal moment for switching (ed. St. USSR No. 867710, cl. 604 41/06. 04.1979). The purpose of the invention is to increase the reliability of the device. The goal is achieved by the fact that the device for controlling a stepped box with automatic gearbox and electronic control system is equipped with an instant vehicle acceleration sensor, a multiplying device, a permanent storage device, a high-speed blocking lock unit, a maximum engine speed detecting unit, an indication unit and a gearbox, the instantaneous acceleration sensor is connected to the first input of the comparator, the second input of which is connected to the output multiplying device, the inputs of which are connected respectively to the engine load sensor and memory output, the comparator output is connected to the first input of the shift blocking block for the highest gear, the second input of which is connected to the engine maximum speed detection unit, the third input is connected to the output of the gear display unit, which is also connected to a memory device, and the output of the blocking block for high gear is connected to the system by controlling the box in front of Ah, the output of which is connected to the input of the block display gear included. In addition, the transmission control system includes a microcomputer with an action program and a forecast system program, and the device is equipped with an instant vehicle speed sensor, and the instantaneous speed and engine load sensors are connected to the inputs of the microcomputer, the outputs of which are connected to the switches shift control devices. The main difference of the control system is that it contains a prognostic system that, immediately before the expected command to shift to the highest gear, estimates the acceleration of the vehicle when driving in low gear and determines the acceleration due to the meticulous conditions of the gears. after shifting to a higher gear, for example according to the approximate ratio a, -K -F where the expected acceleration of the car after shifting from nth to (n -f1) -th before achu; instant acceleration (before shifting to (n + 1) -th gear;
    Ф „is the vehicle's driving force before shifting to (PCh-1) -th gear (corresponding to acceleration a);
    K, is the constant including the weight of the car, the reduced and inertial masses, the corresponding transmission ratio, etc.
    If the expected acceleration a ,. Oh, the prognostic chain allows shifting from nth to (nth1) gear.
    If, then the prognostic chain delays the switching until the condition A., O is met or until the maximum engine speed is reached.
    FIG. 1 shows a block diagram of a device in analog version; in fig. 2 shows a circuit using a microcomputer, the program of which performs the function of the main control and prognostic system.
    According to FIG. 1 The prognostic circuit consists of a chain of instantaneous acceleration measurement of a car, connected to the input or output side of the gearbox and connected to one input of the comparator 5, to the second input of which the output of the multiplying device 4 is connected, to the inputs of which are attached the leads of the 2 measuring force of the pu the vehicle and the storage device 3 are constant K, which includes the weight of the vehicle, inertial masses and the corresponding transmission ratio. The output of comparator 5, which compares the output data of circuits 1 and 4, is connected to one input of circuit 6, blocking the gearshift (n -f1) -th gear, if a „to the next input of circuit 6 is connected to the output of circuit 7, which determines the maximum engine speed - gatel at which circuit 6 is terminated. Conclusion 8 of circuit 6 is simultaneously the output of the complete prognostic system, as well as the input to the appropriate places of the main control or command system 9 of the gearbox, to which the input of the circuit 10 is also connected,redstavl guide feedback to the memory device 3 of the permanent circuit 6.
    The described prognostic chain works as follows.
    Acceleration measurement circuit 1 develops data on instantaneous acceleration a, usually based on the vehicle speed information derived from the output speed of the gearbox. The instantaneous acceleration value in the comparator 5 is compared with the output information of the multiplying device 4, which is the arithmetic product of the data of the chain 2 measuring the force of the string Φ and the constant „,
    corresponding to the weight of the car inertial masses and nth gear. The choice of a constant K from the memory 3 is determined by the transmission indication circuit 10. At the moment when the magnitude of the acceleration a decreases below the value of the product. the comparator instructs the shift lock circuit 6. The blocking action interrupts circuit 7 in the case when the instantaneous engine rpm exceeds the maximum rpm value. Chain 6 receives information about the gear shift from chain 10.
    A microcomputer circuit (Fig. 2) contains a microcomputer 11 with a program 12 of the main control system and a forecast program 13, where information from the speed registration circuit 14 of the vehicle and from the computation power circuit 15 is fed to the corresponding circuits and the microcomputer outputs 15 Maschine 11 is connected directly to switches 16.
    The main control system of a speed-shift gearbox with automatic gear shifting usually develops two output information — the speed of the car, for example, the output speed of the gearbox, and the load of the car, for example, the position of the fuel control control element. Switching the mechanical steps provides the microswitch machine 11 with the help of the entered main program 12. The vehicle speed data from the circuit 14 microcomputer maschine easily transforms into instantaneous acceleration, for example, by re-performing the calculation of the difference between the speed values. Data on the thrust force can be obtained in a microcomputer based on the position of the fuel supply control body or directly, as the output of circuit 15 for recording the vehicle's gravity.
    The forecast program 13 of the microcomputer, ensuring the operation of the predictive system, includes: converting the speed of the car to acceleration; the development of the required information on the power of the FGV, for example, on the position of the fuel supply control authority; indication of the nth gear included; the choice of constant Kfl. corresponding to the inclusion of pth transmission; performing operations of multiplying CRF, 1; comparison of instant acceleration with KPFP value; comparison of instant engine revolutions and the number of maximum revolutions n „4k; issuing a command to blocking the shift to the highest gear when the conditions a. "K" -Fg, and PGP ", kc are met
