Description

一种车辆域控制器新型电路系统
技术领域
本发明涉及车辆电源技术领域，具体来说，涉及一种车辆域控制器新型电路系统。
背景技术
原有的车辆控制器是分散的，是采用分散布置各个附件，附件相互之间配合度低，且DCDC功率远大于车辆需求功率，造成成本过高，各模块之间是采用高压线束进行连接，增加了故障点和成本。因此，需要系统的解决车辆动力分配架构，减少各模块之间的附件，减低成本。
发明内容
针对相关技术中的上述技术问题，本发明提出一种车辆域控制器新型电路系统，能够克服现有技术方法的上述不足。
为实现上述技术目的，本发明的技术方案是这样实现的：
一种车辆域控制器新型电路系统，包括VCU车载通信装置、BMS电池管理、充电控制单元、DCDC计算控制单元、低压保险丝盒、高压配电单元，其中，
所述VCU车载通信装置负责给所述域控制器提供网络通信、数据传输；
所述BMS电池管理负责管理与控制器中的电源供给，配合充电控制单元进行补电；
所述充电控制单元根据DCDC计算控制单元的输入，控制DCDC计算控制单元及各个用电器件的电量输出，进行电源的通断控制；
所述DCDC计算控制单元，负责计算启动电源的SOC状态和各个用电器件功率的计算,进行功率分配；
所述低压保险丝盒中有低压保险丝，用于电路短路和过载的安全维护；
所述高压配电单元用于电力系统中的发电、输电、配电、电能转换和电能消耗过程的通断、控制或保护。
进一步地，在车辆功率消耗大的情况下，DCDC计算控制单元停止向启动电源供电。
进一步地，在车辆功率消耗小的情况下，DCDC计算控制单元给车辆BMS输出功率，且同时向启动电源供电。
进一步地，所述车辆功率消耗大的情况下,DCDC计算控制单元与启动电源一起向车辆的BMS电池输出功率。
进一步地，所述DCDC计算控制单元与启动电源在车辆正常行驶时，同时向整车电气附件提供功率。
本发明的有益效果：通过集成各个用电配件，解决车辆动力分配架构，减少各模块之间的附件，降低DCDC模块的功率，减少接插件和线束，降低成本。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是根据本发明实施例所述的车辆域控制器新型电路系统的各模块结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本发明保护的范围，为了方便理解本发明的上述技术方案，以下通过具体使用方式上对本发明的上述技术方案进行详细说明。
如图1所示，根据本发明实施例所述的车辆域控制器新型电路系统，包括VCU车载通信装置、BMS电池管理、充电控制单元、DCDC计算控制单元、低压保险丝盒、高压配电单元。且域控制器电路由该部件集成。
VCU车载通信装置负责给所述域控制器提供网络通信、数据传输；BMS电池管理负责管理与控制器中的电源供给，配合充电控制单元进行补电；充电控制单元根据DCDC计算控制单元的输入，控制DCDC计算控制单元及各个用电器件的电量输出，进行电源的通断控制。
所述DCDC计算控制单元，负责计算启动电源的SOC状态和各个用电器件功率的计算,进行功率分配。通过DCDC计算控制单元合理分配功率至用电器件，使得电动车采用域控制的DCDC功率要比电动车不采用域控制器的DCDC功率小。
在车辆功率消耗大的情况下，DCDC计算控制单元停止向启动电源供电，DCDC计算控制单元与启动电源一起向车辆的BMS电池输出功率。在车辆功率消耗小的情况下，DCDC计算控制单元给车辆BMS输出功率，且同时向启动电源供电。所述DCDC计算控制单元与启动电源在车辆正常行驶时，同时向整车电气附件提供功率。
所述低压保险丝盒中有低压保险丝，用于电路短路和过载的安全维护；高压配电单元用于电力系统中的发电、输电、配电、电能转换和电能消耗过程的通断、控制或保护。
