Power and post-heating power.
It should be noted that the air intake heater in the present embodiment heats with after starting the most before an engine is started,
Wherein, the state correspondence air intake heater before engine start is in preheated state, and the state correspondence after engine start is entered
Hot-air heater is in post-heating state.In engine starting process, air intake heater is not in duty, now, the most right
Engine charge heats.Owing to engine starting process can produce electric current, if now electromotor is entered by air intake heater
Gas heats, then air intake heater also can produce electric current, and the two superposition causes electric current excessive, easily causes battery discharge excessive
And damage, therefore, in the present embodiment, in engine starting process, air intake heater is not in duty.
S22: take the above-mentioned preheating power maximum with post-heating power as actual heating power.
As it is shown in figure 1, this control device also includes that power chooses module 4, it is used for taking preheating power and post-heating power
Maximum, and this maximum is output as the actual heating power of air intake heater.
Owing to above-mentioned air intake heater has preheated state and two kinds of duties of post-heating state, and it is in pre-when it
During heated condition, post-heating power is zero, and when it is in post-heating state, preheating power is zero, therefore, above-mentioned pre-when taking
During the maximum of heating power and post-heating power, it is possible to filter out the heating power conduct that air intake heater particular state is corresponding
Actual heating power, actual heating power is equal to preheating power or post-heating power.
In the present embodiment, choose module 4 by arranging power so that this control device can be suitable for Poewr control method
Power when air intake heater is in preheated state or post-heating state controls, and is capable of during corresponding states adding hot merit
The automatic screening of rate, is respectively provided with control device and control method without the above two state for air intake heater, from
And make this control device and control method simpler, it is easy to accomplish.
Further, the device that controls in the present embodiment also prestores the target inlet air temperature T of electromotor and inlet air heating
The maximum heating power of device, as shown in Figure 4, step S21 comprises the steps:

Obtain heating corrected output.
As it is shown in figure 1, above-mentioned power computation module 1 includes seeking poor unit 11, for target inlet air temperature T is advanced with working as
Temperature t does difference, to obtain said temperature deviation；Also include that PID regulates unit 12, be used for regulating said temperature deviation, with
To the heating corrected output that this temperature deviation is corresponding.
Wherein, PID unit (proportional integral differential control unit) is a kind of conventional feedback circuit parts, and it passes through will
Heating-up temperature is reduced to substantially linear and dynamic characteristic with the relation of heating power, thus realizes the control to dynamic characteristic, enters
And according to heating-up temperature, heating power being realized feedback control, it is anti-through PID unit that above-mentioned heating corrected output is temperature deviation
Performance number after feedback regulation.
S212: be calculated instantaneous post-heating when air intake heater is in post-heating state according to current intake air temperature t
Power；
Intake air temperature and post-heating power curve L2 as it is shown in figure 1, this control device also prestores, wherein, this temperature with after
Heating power curve L2 is for obtaining above-mentioned instantaneous post-heating power according to current intake air temperature t.
S213: above-mentioned heating corrected output is sued for peace with instantaneous post-heating power, obtains current post-heating power, and judge
Before and after Gai Danging, whether heating power is between zero and maximum heating power, the most then carry out step S214, if it is not, then return
Step S211.
As it is shown in figure 1, this power computation module 1 includes sum unit 13, the input value of this sum unit 13 is above-mentioned adding
Hot repair positive and instantaneous post-heating power, after the two being sued for peace, the output valve of this sum unit 13 is above-mentioned current post-heating
Power, before and after deserving, heating power is the heating power after PID regulates that current intake air temperature t is corresponding；Also include judging
Unit 14, is used for judging that current post-heating power is whether between zero and maximum heating power.
It is appreciated that the heating corrected output after PID regulates may be relatively big or for negative value, thus causes current post-heating
Power is relatively big or be that the situation of negative value occurs, it is clear that the current post-heating power under both of these case deviates actual value.This enforcement
In example, by arranging judging unit 14 so that the virtual value of above-mentioned current post-heating power be positioned at zero with maximum heating power it
Between, tally with the actual situation.
S214: judge whether air intake heater is in post-heating state, the most then before and after deserving heating power be above-mentioned after
Heating power, if it is not, then post-heating power is zero.
Further, above-mentioned control device also prestore electromotor start after minimum speed be setting speed, and prestore send out
The object run time of motivation is the setting time, and as shown in Figure 6, step S214 comprises the steps:
S2143: judge that engine speed, whether more than above-mentioned setting speed, and judges that the actual run time of electromotor is
No less than the above-mentioned setting time, the most then enter step S2144: air intake heater is in post-heating state, now, when front and back
Heating power is above-mentioned post-heating power；If it is not, then enter step S2145: air intake heater is not in described post-heating state,
Now, post-heating power is zero.
Correspondingly, the control device shown in Fig. 1 also includes post-heating judge module 3, is used for whether judging air intake heater
It is in post-heating state, the most then will determine that the current post-heating power that unit 14 exports is output as above-mentioned post-heating power, if
No, then the post-heating power exported is zero.
Specifically, above-mentioned post-heating judge module 3 is used for judging that whether engine speed is more than above-mentioned setting speed, and sentence
Whether the actual run time of disconnected electromotor is less than the above-mentioned setting time, the most then this air intake heater is in post-heating state,
If it is not, then this air intake heater is not in post-heating state.
The post-heating judge module 3 being appreciated that in the present embodiment is to include the module with logic, and prestore some after
Heated condition enables condition B, and this post-heating state enables condition B and comprises the steps that engine speed setting speed, electromotor run
Time sets time, inlet air temperature set temperature, cell voltage setting voltage, engine speed sensor and intake air temperature
Sensor fault-free etc., wherein, setting voltage is battery minimum voltage when can normally work, cell voltage setting voltage
Purpose is set for preventing battery from electric deficiency phenomenon occur owing to voltage is the least.
By arranging this post-heating judge module 3 so that when meeting above-mentioned each post-heating state enable condition B, air inlet adds
Hot device is in post-heating state, and to power, the output of above-mentioned post-heating power is chosen module 4.
