Counterblocking system of motor vehicle

专利摘要:
A wheel anti-skid brake control system for controlling the braking effort of the four wheels of a motor vehicle. The system includes a speed sensor, an electronic evaluating circuit, a monitoring safety circuit, a switching device and a solenoid regulated valve for each wheel for deactivating the braking effort of a pair of diagonally opposed wheels when a malfunction occurs in an associated electronic evaluating circuit.

This invention relates to the automotive industry.
The purpose of the invention is to increase the value.
I FIG. 1 shows a block diagram of the locking system of the car; in fig. 2 - the same, another variant; 1; in fig. 3 - the same, the third embodiment; in fig. 4 - the same, the fourth embodiment.
The anti-vehicle system of the automobile (Fig. 1), having four wheels 1-4, is equipped with sensors 5-8 of the dynamic state of the wheels and electromagnetic valves 9-12. The output signals of the sensors 5 and 7 of the diagonal of the car are attached to the first electronic node 13. This electronic node 13 controls the valves 9 and 11. The electronic nodes 13 and 14 contain E circuits (forming the speed reference signal, as well as SIS safety circuits, SIS, In this case, the SIS4 and SIB schemes for the electronic node 14 are located completely or partially in the node 13, and the SIS and SISj schemes are wholly or partially in the node 14. The electronic nodes can be located on separate substrates.
The power supply of the nodes 13 and 14 is carried out from the battery of the car 15 through two fuses I6 and 17.
. The SIS and SIS 1 safety circuits in node 13 receive, via line 18, the signals to be monitored from the circuits. E4 and E2 of node 14 and disable adjustment of node 14 in case of an error by means of a signal to electronic switches 19 and 20. Similarly, the SIS and SISj circuits control the circuits E and E j using switches 21 and 22. In the case of nor, the alarm turns on lamp (not shown).
The system of FIG. 2 differs from the system of FIG. 1 in that the control circuits of both electronic components 13 and 14 are completely disconnected from each other. Designed for a single node (for example, node 13), SIS and SIS3 safety circuits are also located in this node. At the same time, the SISi circuits are located in the control circuit E of the electronic unit 23, and the SIS safety circuit is located in the E control circuit of the electronic unit 24. In the same way, the blocks 25 and 26 are formed by the SISj E and SIS, E .
Due to the fact that nodes 13 and 14 are completely independent of each other, the resulting errors in the control loop do not exert a negative effect on braking even when the safety circuit is also defective. A fault anywhere in the system affects the braking performance of only one diagonal.
The power supply of the nodes 13 and 14 can be carried out without fuses 16 and 17 (Fig. 3) or via electronic switches 27 and 28 (Fig. 4).

Invention Formula
The car's anti-blocking system contains control circuits for each wheel, each control circuit includes a wheel dynamic sensor connected to an electronic data processing unit connected to a current source and having a reference speed signaling circuit and an electronic control circuit a switch, as well as a brake pressure regulating solenoid valve connected to the electronic unit, and the signal formation circuit growth and safety circuit - made in the form of integral nodes, and the safety circuit of one control loop is located in the integral node of another control loop, so that, in order to increase the reliability, the electronic control units contours for wheels located along one diagonal are combined in. One node that has at least one electronic switch and is connected by a separate circuit to a current source, and the safety circuits are placed in the specified node.
