Fig. 2 is the utility model electrical equipment connection diagram.
Fig. 3 is each element circuit of the utility model.
Embodiment
Below in conjunction with the electrical equipment connection diagram, the utility model is done explanation further through the groundwork process.
Controller when key is beaten to the ON shelves, is judged engine water temperature through detection of engine water temperature and battery tension, if engine water temperature is higher than 12 ℃, then presses normal starting control, controls actuating motor through judging the ST shelves.If when engine water temperature is lower than 12 ℃, can carry out preceding rre-heated, define preceding preheat time like following table:
Before preheating and in the warm, controller is constantly monitored battery tension.When battery tension is lower than 10v (12v system), 20v (24v system), will not use electric heater, preventing the serious feed of storage battery, thereby damage storage battery.
Warm-up phase before execution; Controller is closed the output control of actuating motor automatically, the user can't actuating motor through key ST shelves, thereby has avoided cold day not under the situation of preheating; The motor that long-time Fraquent start motor causes is crossed cause thermal damage, has prolonged actuating motor working life.In addition, in preceding preheat time of section, controller can remind the user carrying out preceding rre-heated with the flicker frequency of 1 time/per second through the preheating tutorial light on the vehicle body instrument.
After preceding warm-up phase finishes, wait for user's starting.Bootwait time 60s waits for that in the starting time, the power supply of electric heater is closed in control, stops rre-heated.If in the time, the user is through key ST shelves normal starting motor at bootwait, then pre-heating system works on a period of time, and this stage is the back heating period.Back heating period stop condition is: engine water temperature>18 ℃, perhaps the back surpasses 30s heating time.After the back heating period finished, whole warm stopped.In addition, the back heating period, preheating tutorial light Chang Liang is carrying out the back heating function to remind the user, and after the back heating period finished, the preheating tutorial light extinguished.If after the bootwait time finished, the user piloted engine through key ST shelves, then pre-heating system is carried out elder generation's heating period and follow-up again and is added heat control.
Can adjust through software programming all preheat times according to user's actual demand.The diesel vehicle that this controller can be assemblied in charged heater (comprising similar products) uses.
