Description
Technical field
The invention belongs to automobile ABS safety testing field, particularly electronic stabilizing control system to fill without back pressure functional test
Put.
Background technology
ESC electronic stabilizing control systems are made of ESC controllers and ESC fluid pressure governor two parts.ESC fluid pressure governors
By 1 motor, 2 plunger pumps, 2 accumulators, 2 reversal valves, 2 make-up valves, 4 pressure charging valves, 4 pressure reducing valves and various oil
Road forms, there are two oil inlets and four oil outlets in its surface.Two oil inlets connect the front and rear chamber of master cylinder respectively, and 4 go out
Caliper of the hydraulic fluid port respectively with 4 wheels is connected.The effect of ESC electronic stabilizing control systems：, can be real when brake pedal is stepped on
Existing conventional brake and ABS ANTI LOCKs；In understeer or ovdersteering, by carrying out active system to single wheel
It is dynamic, so that vehicle produces a torque around this wheel, help automobile increase or reduce turning radius.Pass through ESC controllers
Different sensor signals is gathered, the various original paper interoperations in ESC fluid pressure governors is controlled, realizes different functions.
For automobile ESC active boosts there are two kinds of operating modes, first, driver steps on brake pedal, when brake force is insufficient,
There are ESC trigger signals, just there are extra pressure, this is the oil inlet end (i.e. master cylinder side) of scavenge oil pump before ESC active boosts
There is back pressure operating mode；Second, when driver does not step on brake pedal, there are ESC trigger signals, the oil inlet of scavenge oil pump before ESC active boosts
Extra pressure is not present in end (i.e. master cylinder side), this is no back pressure operating mode.ESC electronic stabilizing control systems detection device using source of the gas as
The brake fluid of fuel tank is pumped into hydraulic system by power source, driving gas-liquid booster, and simulation foot, which is stepped on brake pedal and built, presses through journey, by
Overflow valve limits the maximum pressure of system, and when normally opened Solenoid ball valve no power, system maximum pressure is 16MPa, normally opened electromagnetism
When ball valve is powered, system maximum pressure is 25MPa, by controlling the keying between normally closed electromagnetic ball valve group, it is possible to achieve ESC's
ABS functional tests and tested with back pressure active boost, in former detection device, fuel tank is placed in detection device bottom, and detected member is put
In detection platform, and two check valves that gas-liquid booster carries are there is also certain Opening pressure, therefore without back pressure active boost
When, negative pressure state is in equivalent to detected member entrance, existing apparatus can not realize being tested without back pressure active boost for ESC.
By verification, find there is the existing detection device in part to examine qualified ESC fluid pressure governors to go out in real train test
The situation that existing active boost can not built.Main cause is that existing detection device can only test the ESC actively increasings of back pressure
Journey is pressed through, and the ESC active boost processes under no back pressure operating mode cannot be tested.
