In the normal straight of power actuated vehicle to overtake in the process, the Y-axis signal that acceleration pick-up A collects is very little, door threshold level value with comparator B1 after preamplifier A1 amplifies compares, if comparator B1 does not have signal output, so the signal that micro controller system C2 gathers is 0, do not have the demonstration of horizontal cross, be considered as the normally straight-line travelling forward of power actuated vehicle.And when vehicle quickens or drives over the speed limit, the X-axis signal that acceleration pick-up A collects, the variation of the inertia of speed forward that travels according to car, door threshold level value with comparator (B2) after preamplifier A2 amplifies compares, comparator B2 has signal output, by the A/D D/A, analog signal conversion is become digital signal, at this moment, micro controller system C2 gathers signal, and, drive the straight-line motion state parameter of demonstration, writing circuit demonstration or registration of vehicle by calling in default external program operation.Micro controller system is being gathered, is being handled from the overspeed signal of the Y-axis felt the utility model, when the differentiation of signal and control, and carries out by the overspeed signal external subroutine in the external program memory of micro controller system.The utility model can be used as the active cue of vehicle from the overspeed signal felt, and technology expands means for the intellectualized management of chaufeur and traffic management system provides easily.
When vehicle was moveed backward, micro controller system was gathered, is handled the reversing automobile signal of the X-axis felt certainly, the differentiation of signal and control, and will carry out by the reversing automobile signal external subroutine in the external program memory of micro controller system.Independent and the state of monitoring record display automobile reversing at any time of the utility model becomes the safety monitoring system that is independent of outside vehicle circuit, oil circuit and the mechanical transmission mechanism.
2), vehicle is in the straight line braking mode:
In the straight-line travelling process of power actuated vehicle, the appearance situation, when vehicle is in the straight line braking mode, the X-axis signal that acceleration pick-up A collects, the speed inertial change of travelling according to car produces sudden change, door threshold level value with comparator (B1) after preamplifier A1 amplifies compares, comparator B1 has signal output, by the A/D D/A, analog signal conversion is become digital signal, at this moment, micro controller system C2 gathers signal, micro controller system is gathered from the deceleration and the emergency brake signal of the X-axis of feeling the utility model, handle, the differentiation of signal and control, and carry out to drive by deceleration in the external program memory of micro controller system and emergency brake signal external subroutine and show, the straight line braking mode of writing circuit demonstration or registration of vehicle.The utility model because of having saved subjective opening time, sends warning from the brake signal that the comparable traditional subjectivity action of the restriction signal of the X-axis of feeling produces in advance.
3), the cross motion state of vehicle:
Turn to or unexpected left and right evading when getting rid of power actuated vehicle normal left and right, the Y-axis signal that acceleration pick-up A collects changes at the transverse inertia that turns to, gets rid of head/wag the tail according to car, door threshold level value with comparator B2 after preamplifier A2 amplifies compares, comparator B2 has signal output, by the A/D D/A, analog signal conversion is become digital signal, at this moment, micro controller system C2 gathers signal, and, drive the cross motion state of demonstration, writing circuit demonstration or registration of vehicle by calling in default external program operation.Independent and the monitoring record display automobile left and right sides turn sign at any time of the utility model becomes the safety monitoring system that is independent of outside original vehicle circuit.
4), car stowage, be in static, the anti-theft alarm state of setting up defences:
Vehicle be in deposit static, during state that anti-theft alarm is set up defences, if someone is without the normal antitheft program of withdrawing a garrison, destroyed anti-theft alarming equipment into the car and in time, when the car startup is sailed out of, the inertia that any axis signal of Y that acceleration pick-up A collects or X monitors vehicle changes, the signal of this variation amplifies the door threshold level value comparison of back and comparator B1 or B2 through preamplifier A1 or A2, this moment, comparator had signal output, by the A/D D/A, analog signal conversion is become digital signal, at this moment, micro controller system C2 gathers signal, and by calling in default external program operation, drive and show, the state of kinematic motion of writing circuit demonstration or registration of vehicle, and, start the GPS global location warning that is provided with in the car automatically by control interface, promptly notify the owner of car, reach the purpose of safe antitheft.
