Refer to shown in Figure 3ly, the invention provides the control method of a kind of passenger vehicle front electricity defrosting glass power safety, comprise the steps:
1., the driver is while needing front electricity defrost function to start, and presses the master cock 1 on instrument desk, this microprocessor 23 namely can collect this instruction by sampling interface circuit 24;
2., this microprocessor 23 checks CAN bus communication state by CAN controller 22 immediately, as normally, 23 of this microprocessors are in starting state (discriminant value: rotating speed is greater than 400RPM) and the vacant air-conditioner generator 200(of a/c system discriminant value by CAN bus message validation of information driving engine: air-conditioner generator excitation level); If driving engine unstart or a/c system have taken air-conditioner generator 200, do not carry out defrost operation;
3., again after confirming that relevant information is passed through, microprocessor 23 is namely by the closed generator excitation power relay 4 of control interface 25 and main power circuit relay, to start front electricity defrost function; Preferably, also simultaneously by the CAN bus send " the electricity defrosting is working properly, does not start simultaneously a/c system " information to instrument treater 6 with the prompting driver, after receiving this information, instrument treater 6 is the collaborative Air-condition system control power supply of cutting out simultaneously;
This step 2. in, if engine speed is greater than 400RPM, judge that driving engine is in starting state; If air-conditioner generator 200 excitation level are in high level, judge that a/c system has taken air-conditioner generator 200.
In addition, further, in order to improve safety, this control method also comprises:
4., monitor in real time resistor wire 310 loop currents of front electricity defrosting glass, if it is abnormal that resistor wire 310 loop currents occur, by the CAN bus, send alerting signal to instrument, also by control interface 25, control excitation source relay 4 simultaneously and disconnect, to cut off front electricity defrosting glass power supply.Particularly, please refer to shown in Figure 2,
This micro-processing gathers the signal (current value of collection adopts I to mean) of current sensor 5 by sampling interface circuit 24, and data are monitored in real time.As can be known by empirical data, average current during single resistor wire 310 normal operation is △ I, consider resistor wire 310 resistance value difference as can be known with reference to electric defrosting glass working current test figures under different temperature condition to some extent under condition of different temperatures, the running current IN of every two resistor wires 310 should be at θ △ I in η △ I scope, and with reference to discriminant value, be namely: θ △ I<IN<η △ I(wherein θ, η is constant).Thus, the current value of these microprocessor 23 real-time more current samplings and setting reference value, if I is operated in outside normal range, can be judged as resistor wire 310 short circuits/open circuit conditions, microprocessor 23 is just by control interface 25 cut off the electricity supply loop relay and generator excitation power relay 4, simultaneously by the CAN bus send electricity defrosting short circuit/breaking alarming information to instrument treater 6 with prompting driver electricity defrost function fault so that maintenance.
When the work of front electricity defrosting glass, if the driver presses the master cock 1 on instrument desk again, after this microprocessor 23 collects this instruction by sampling interface circuit 24, just by control interface 25 cut off the electricity supply loop relay and generator excitation power relay 4, by the CAN bus, sending " the electricity defrosting quits work " information simultaneously closes with prompting driver electricity defrost function to instrument treater 6, after receiving this information, instrument treater 6 is the collaborative unlatching Air-condition system control power supply that recovers simultaneously; In the present embodiment, this CAN bus adopts SAE-J1939 as communications protocol.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field, to its suitable variation or modification of doing, all should be considered as not breaking away from patent category of the present invention.
