DEVICE FOR BOARD DIAGNOSIS OF VEHICLE BRAKING SYSTEM Russian patent published in 2017 - IPC B60T17/22 

FIELD: automotive industry.

SUBSTANCE: device for board diagnosis of a vehicle braking system comprises a brake pedal (4) sensor (1) with the pulse inverter (2), differentiating circuit (5) arranged on the two resistors (6, 7), the condenser (8) and shutoff a diode (9), eight-bit summing electronic counter (10) with eight outlets (11, 12, 13, 14, 15, 16, 17, 18), input for setting zero (19) and counting input (20), eight light emitting diodes ( 21, 22, 23, 24, 25, 26, 27, 28), each of which is connected to one of the eight outlets of the counter, resistors, multivibrator (29). The impulse converter of the brake pedal (4) sensor (1) is slotted and mounted on the bracket (3) near the brake pedal (4), so that the pedal (4) can be moved in the slots of the inverter (2). A multivibrator (29) made self-oscillating symmetrically on two logic elements (30, 31), two capacitors (32, 33), two resistors (34, 35) and two diodes (35, 37), the input is connected with by a resistor (38) to the output of the pulse inverter (2), and the output by means of a resistor (39) with a counting input of the summing electronic counter (10). The differential circuit (5) is connected with the input to the output of the pulse inverter (2), and the output is connected to the input of the electronic totalizing counter (10) zero.

EFFECT: expansion of the device functionality, increased safety of driving and reduced cost of repairing vehicles by determining the actual technical condition of the vehicle brake system directly in the process of its operation and then eliminating misalignments and faults, if they are found.
