The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present invention is elaborated.Present embodiment is being to implement under the prerequisite with the technical solution of the present invention, provided detailed embodiment and concrete method of operation, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, PTC heating control system of the present invention comprises: PTC control module 10, three positive temperature coefficient electrical heating elements PTC9, environment temperature sensor 1, interior temperature sensor 3, cooling-water temperature sensor 2 and relays 8.Referring to Fig. 1,2,3, wherein PTC control module 10 is arranged on the HVAC housing, and PTC9 is arranged in HVAC housing the inside, and the heating material of PTC9 is generally ceramic thermistor material or semi-conductor thermoelectric material.
As shown in Figure 1, the power of PTC9 heating is divided into 3 gears, adapts to different heating demands respectively.Environment temperature sensor 1, interior temperature sensor 3 and cooling-water temperature sensor 2 all adopt NTC thermally dependent resistor, low price and dependable performance commonly used.
Press the button of air-conditioning panel 4 as chaufeur,, when starting PTC9 work, need judge whether normal operation of electric generator of vehicle 6,, then do not allow PTC9 to start as electrical generator 6 operation irregularities then in order to prevent vehicle over discharge when electrical generator 6 is not worked.This logic is to realize by the discharge deixis 5 that electrical generator 6 is connected on the instrument, does not start then the discharge indicator lamp 5 of instrument as electrical generator 6 and lights, and after the normal output of electrical generator, this indicator lamp 5 extinguishes.The present invention is incorporated into the PTC control module with this signal by lead, realizes the judgement to electrical generator 6 states.
After judging that electrical generator 6 starts, PTC control module 10 is by self in pin monitoring storage battery 7 voltage swings in real time, as continues for some time and be lower than 12V, and PTC control module 10 can forbid that still PTC9 starts, unless storage battery 7 voltage stabilizations are more than 12.5V.Normal as car load storage battery 7 voltages, PTC control module 10 can receive the temperature of driving compartment in present vehicle ambient temperature of living in, the car and the temperature of engine coolant simultaneously, by the input of comprehensive these sensors of judgement and the desired temperature of chaufeur, PTC control module 10 starts, send low level signal, make relay 8 adhesives, select PTC9 in suitable gear engaged.After the temperature in the car reached the temperature of chaufeur setting, the PTC module was exported unsettled in addition, and relay 8 disconnects, and PTC9 quits work.
In order to protect the car load storage battery, the PTC control module has been set the maximum operating time of PTC9, as exceeds this time in addition, no matter whether vehicle interior temperature reaches design temperature, PTC9 all will quit work.
The present invention has warning function in addition, sent the order of ending PTC9 work as PTC control module 10, and actual PTC9 works still, and PTC control module 10 can remind chaufeur to note by the flicker of air-conditioning panel indicator lamp 4.
