Embodiment
Technical scheme is further elaborated with reference to embodiment and attached drawing.
Embodiment 1
A kind of halogen lamp input voltage optimal control method is present embodiments provided, it includes：
S10, by sensor obtain the battery status parameters such as battery capacity, cell voltage, charging current and battery temperature,
And the battery status parameter is transferred to control unit of engine.
In the present embodiment, the sensor can include current sensor, and the current sensor is installed on storage battery negative
On extremely, communicated by LIN buses and control unit of engine.
S20, by accelerator pedal position sensor obtain gas pedal aperture, and the gas pedal aperture is transferred to hair
Motivation control unit, it is preferable that the gas pedal is communicated by rigid line and control unit of engine.
S30, by Der StandlichtScheinwerfer und Parkleuchtenschalter obtain headlight open and-shut mode signal, and by the open and-shut mode signal of the headlight send to
Car body controller, and sent the open and-shut mode signal of headlight to control unit of engine, this implementation by the car body controller
In example, the Der StandlichtScheinwerfer und Parkleuchtenschalter is communicated by rigid line and car body controller.
S40, control unit of engine are connected by LIN buses with intelligent generator, control the output electricity of intelligent generator
Pressure, so as to power to halogen lamp.
In the present embodiment, the step S40 is specially：
When headlight is opened：The limitation voltage of intelligent generator is adjusted to maximum by the control unit of engine, intelligence
Generator is according to battery status parameter output voltage so that output voltage is without obvious fluctuation, and halogen lamp changes without light and shade, i.e., when big
When lamp is opened, controlled without intelligent generator.
When headlight is closed：The control unit of engine determines that engine is in acceleration mode according to gas pedal aperture
In the case of and SOC value be more than or equal to 50%, or SOC value higher than setting peak, such as：90%.Intelligence hair will be reduced
The output voltage of motor, until reach minimum limitation voltage (control intelligent generator is in relatively low limitation voltage, such as
10.8V), intelligent generator torque demand is reduced, so that more power are used to accelerate；The control unit of engine is according to oil
Door pedal aperture determines that engine is in the situation of deceleration regime and SOC value is less than or equal to 90%, or SOC value is less than setting
Minimum, such as：50%, the output voltage of intelligent generator will be raised, until reaching highest limitation voltage (control intelligence hair
Motor is in higher limitation voltage, such as 16V), by superfluous mechanical energy to needing battery to charge, maximumlly mechanical energy is turned
Turn to electric energy；The control unit of engine determines that engine is at the uniform velocity state according to gas pedal aperture, and SOC value meets
Sets requirement, such as more than or equal to 50% and less than or equal to 90%；It will keep current output voltage.That is, when headlight is closed,
Intelligent generator is controlled.
To meet the requirement of fuel economy regulation, each main engine plants all increase the measure of a series of drop oil consumption, and one of which is exactly
Intelligent generator is matched, realizes the energy management of vehicle.
Control unit of engine judges vehicle running state according to signals such as current throttle aperture, speed, wheel speeds；Further according to
The parameters such as the accumulator parameters such as battery capacity, cell voltage, engine load carry out generator output voltage limitation and adjust.Hair
Motivation control unit 10.8~16V within the scope of defined by the output voltage control of generator.Under equal battery status,
When vehicle load is larger, such as anxious to accelerate operating mode, control unit of engine limitation generator output voltage is relatively low, makes engine
More energy go to provide vehicle power output；When vehicle load is relatively low, control unit of engine limitation generator output electricity
Pressure is high, generator is provided more outputs and goes to charge a battery, to vehicle-mounted electric power supply.So carry out rational energy point
Match somebody with somebody, achieveed the purpose that to save oil consumption.
When carrying out intelligent generator adjusting, output voltage has the voltage fluctuation of 0.5V-0.7V.Since halogen lamp is to electricity
The sensitive characteristic of pressure fluctuation, and inexpensive vehicle can not bear the voltage stabilizing device of costliness, halogen lamp have strong quick
Sense change, driver substantially feel that headlight is dimmed when refueling, and causes strong complaint.
To solve the problems, such as this, the present invention introduces headlight status signal when being controlled to intelligent generator；Pass through vehicle body
Headlight virtual condition is inputed to control unit of engine by controller.When headlight is closed, control unit of engine carries out intelligence
Generator control is adjusted.When headlight is opened, control unit of engine adjusts the output voltage of intelligent generator to maximum,
Intelligent generator will be according to battery status output voltage under this state, and output voltage is without obvious fluctuation, and halogen lamp is without light and shade
Change.Not only having met vehicle reduces the contribution demand of oil consumption, but also meets the requirement of sense of driver.
The sequencing of above example only for ease of describing, does not represent the quality of embodiment.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：It still may be used
To modify to the technical solution described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical solution spirit and
Scope.
