Description
技术领域
本发明涉及发电机控制领域,特别涉及一种车载发电机控制***。
背景技术
汽车发电机按照输出电流类型不同可分为直流发电机和交流发电机,考虑到成本、结构等方面问题,当前大部分汽车装配的都是交流发电机。大部分汽车选用的是硅整流交流发电机,主要由转子、定子、电刷与滑环机构、三相桥式整流器、电压调节器、轴承风扇和前后端盖等组成。一般来说,发动机的转速约在500r/min到5000r/min之间,发电机的输出电压跟转速有一定关系,转速的变化幅度大会引起发电机输出电压的不稳定,可能会无法满足汽车电气设备的要求。对于整车的用电设备来说,为了避免由于发电机转速的不稳定造成的电压波动,车载发电机需要配有电压调节器来稳压。电压调节器的基本原理:发电机的输出电压与发电机的转速、发电机定子线圈的匝数和发电机转子线圈产生的磁通量的大小这三个因素有关。由于发电机的转速时刻变化;定子线圈的匝数是固定不变的,因此电压调节器只能通过调节磁通量大小来稳定电压。如图1所示,即外搭铁型电压调节器的基本电路。该基本电路是由三只电阻R1、R2、R3,两只三极管Vt1、Vt3,一只稳压二极管VS组成。电压调节器正是利用二极管的单向导通性和三极管的开关特性,能够控制交流发电机励磁电路的断开与导通,将发电机的输出电压稳定在14V左右,但是不能对发电机的输出电压大小进行调节。无法调节输出电压大小的发电机使得无法对发电机的输出电能进行有效管理,导致车辆能耗增加。
发明内容
为了解决车载发电机输出电压无法调节输出电能无法进行有效管理的问题,本发明提供了一种车载发电机控制***,具体方案如下:
一种车载发电机控制***,包括LIN总线和通过LIN通信建立通讯网络的主机控制单元、电池传感器、电压调节器,主机控制单元为通讯网络的主机节点;其中电压调节器与发电机的输出端连接;***包括以下工作步骤:
S1、主机控制单元通过电池传感器采集电池信息;
S2、主机控制单元处理电池信息,并判定电池状态;
S3、主机控制单元通过LIN总线向电压调节器发送控制指令使得发电机进入对应的工作状态。
具体地说,所述电压调节器包括EMC电路。
具体地说,所述电池传感器包括输入电路和与输入电路对应引脚连接的电流采集通道、电压温度采集通道,电流采集通道包括依次设置的分流器、运算放大器、第一模数转化器,电压温度采集通道包括第二模数转化器和温度传感器,第二模数转换器分别连接温度传感器和输入电路,其中第一模数转换器、第二模数转换器的输出端与LIN总线连接。
具体地说,步骤S2具体为:计算电池的SOC;当SOC>80%,电池处于回收区间;当20%<SOC≥80%,电池处于工作区间;当SOC≤20%,电池处于亏电区间。
具体地说,所述发电机包括以下工作步骤:
A1、发电机不工作且LIN总线上没有激活指令时进入待机状态;
A2、通过LIN总线上的激活指令和同步-中断信号激活发电机,发电机激活后且发电机转速nG<n0时,主机控制单元发送有效设定电压US,且US>U0,发电机进入预励磁状态;
A3、当设定电压US>U0,且转速大于n0时,进入调压状态;
发电机激活后的初始状态为关闭励磁,主机控制单元没有发送新的指令前一直有效;n0为启动转速门限值,nG为发电机实时转速,US为发电机设定电压,U0为预励磁门限值。
具体地说,所述调压状态包括当过电压产生时调节相电压至励磁门限电压Un;当欠电压产生时调节发电机电压使得电压降最小;当发动机转速波动大于设定阈值时通过负载响应时间参数t_R对占空比的增速进行限定。
具体地说,当LIN总线上无激活指令且转速超过设定值n1,发电机进入紧急启动状态,电压调节到预设值,当检测到转速超过紧急启动转速阈值时,进入调压状态且发电机以默认值工作。
具体地说,当发电机工作在预励磁状态时,对发电机脉冲以设定占空比进行调制。
具体地说,步骤S3具体为:
S3.1、主机控制单元控制发电机进入调压状态;
S3.2、当电池SOC处于回收区间时,主机控制单元调低US或关闭励磁,让蓄电池参与为负载提供电能,有效降低发动机的燃油消耗;
当电池SOC处于工作区间时,主机控制单元调高设定电压US或使用默认设定值工作,给蓄电池充电以回收制动能量;
当电池SOC处于亏电区间时,主机控制单元提升设定电压US让发电机给蓄电池进行快速充电,从而使得蓄电池SOC位于工作区。
本发明的有益效果在于:
(1)本发明提出包括LIN总线通讯网络的车载发电机控制***,有效地针对车载电池的不同工作状态调整发电机的输出电压,实现了对发电机输出电能的有效管理使得电池和发电机工作在最优的工作区间,提高车载电池的寿命的同时降低车辆能耗。
(2)当过电压产生时,通过调节相电压至Un,避免了发电机无励磁以及电气故障标志的置位;当欠电压产生时,通过调节电压使的电压降最小,欠电压会被调节到门限值,也就是说,即使是在负载响应功能激活的情况下,低于该门限电压的部分也会被快速调节;当发电机转速波动大于设定阈值时,通过负载响应时间参数t_R对占空比的增速进行限定可以在启动阶段减少发动机的负担。
(3)在预励磁状态下对发电机脉冲进行调制使得发电机产生足够的励磁以感应转速信号,这样可以保证所感应的转速信号能被准确探测。
