具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。
图1是本申请实施例提供的一种热管理控制方法的流程图，本实施例可适用于热管理分析情况，该方法可以由热管理控制装置来执行，如图1所示，包括如下步骤：
S110、获取当前动力总成的温度。
S120、当当前动力总成的温度达到预设温度阈值时，根据动力总成功率及动力总成功率变化率调节热管理控制参数；或者，当当前动力总成的温度达到预设温度阈值时，根据温度变化率调节热管理控制参数；其中，热管理控制参数包括热管理组件工作参数及动力总成达到的目标温度阈值。
其中，该热管理控制方法应用于热管理系统，热管理系统包括热管理组件和动力总成；整车的热管理系统是通过水冷却管路将动力总成和热管理组件连接起来，通过冷却介质对动力总成和外界环境进行热交换，使动力总成工作在最佳温度范围内。实际的控制过程中，由于动力总成的热特性不同，不同的动力总成的工作效率会随着温度变化，动力总成的发热功率从而也会随着温度变化。
若当前动力总成的温度未达到预设温度阈值时，此时动力总成的工作效率不发生变化，动力总成的发热功率变化平缓，动力总成温度变化平缓，则保持热管理控制参数恒定，即使得热管理组件工作参数恒定，动力总成达到的目标温度阈值也恒定不变。
若当当前动力总成的温度达到预设温度阈值时，动力总成的工作效率会突 然下降，动力总成的发热功率会突然升高，动力总成的温度会急剧增加，因此整车控制器会通过采集并根据动力总成的功率及动力总成功率变化率进行预测未来动力总成的温度增加幅度大小，从而适当调节热管理控制参数，即调节提高热管理组件工作参数，调节降低动力总成达到的目标温度阈值，从而保证动力总成温度精确地控制在理想的范围内。
另外，当前动力总成的温度达到预设温度阈值时，动力总成的工作效率会突然下降，动力总成的发热功率会突然升高，动力总成的温度会急剧增加，因此整车控制器还可以根据未来一段时间的温度变化是否偏离温度增幅，从而适当调节热管理控制参数，即调节提高热管理组件工作参数，调节降低动力总成达到的目标温度阈值，使得动力总成温度精确地控制在理想的范围内。
本申请实施例，通过获取当前动力总成的温度，当当前动力总成的温度达到预设温度阈值时，根据动力总成功率及动力总成功率变化率调节热管理控制参数；或者，当当前动力总成的温度达到预设温度阈值时，根据温度变化率调节热管理控制参数；其中，热管理控制参数包括所述热管理组件工作参数及所述动力总成达到的目标温度阈值。如此基于动力总成的热特征，根据动力总成的功率及功率变化率预测动力总成的温度变化趋势，或直接根据温度变化率预测其温度变化趋势，从而调节控制策略，使动力总成温度精确控制在理想范围内。
图2是本申请实施例提供的一种热管理系统的结构示意图，如图2所示，热管理系统包括动力电池11、电冷却装置12及第一水泵13；动力电池11、电冷却装置12及第一水泵13通过冷却介质管路14构成一循环回路(即动力电池循环回路)；电冷却装置12的作用是给动力电池11提供电冷却源。动力电池循环回路具备动力电池冷却功能。参照图2，热管理系统还包括动力电机15、第二水泵18、热交换装置16及风扇17；动力电机15、第二水泵18及热交换装置16通过冷却介质管路14构成另一循环回路(即动力电机循环回路)；风扇17与热交换装置16耦合连接；第二水泵18可以驱动冷却介质在冷却介质管路14中 流动；热交换装置16的作用是使得动力电机15产生的热量与外界大气交换；风扇17则可以加速热交换装置16与大气热量交换；动力电机循环回路具备动力电机冷却功能。
需要说明的是，动力总成包括动力电池11和动力电机15，热管理组件包括电冷却装置12、第一水泵13、第二水泵18、热交换装置16及风扇17。
由于动力电池和动力电机的热特性不同，下面分别对动力电池循环回路和动力电机循环回路进行不同的调节热管理控制，图3是本申请实施例提供的另一种热管理控制方法的流程图，参照图2和图3；该方法包括:
S210、判断动力电池是否达到第一预设温度阈值，判断动力电机是否达到第二预设温度阈值；其中，第二预设温度阈值大于第一预设温度阈值。
其中，各动力总成的热特性不同，不同的动力总成的工作效率会随着不同的温度变化；动力电池当达到第一预设温度阈值时，其动力电池的工作效率会突然下降；动力电机当达到第二预设温度阈值时，其动力电机的工作效率会突然下降；由于动力电机的工作效率受温度影响较小，动力电池的工作效率受温度影响较大，因此，第二预设温度阈值大于第一预设温度阈值。
S220、当当前动力电池的温度达到第一预设温度阈值时，根据动力电池功率及动力电池功率变化率调节热管理控制参数，或者，当当前动力电池的温度达到第一预设温度阈值时，根据动力电池温度变化率调节热管理控制参数；其中，热管理控制参数包括电冷却装置输出的预设冷却功率、第一水泵转速及动力电池达到的目标温度阈值。
示例性的，当当前动力电池的温度达到第一预设温度阈值时，动力电池功率小于预设功率，动力电池功率变化率小于预设功率变化率时，则不调节热管理控制参数。
其中，在一般的热管理控制策略中，当动力电池的温度未达到第一预设温度阈值时，动力电池循环回路中电冷却装置输出的预设冷却功率、第一水泵的转速及动力电池达到的目标温度阈值为恒定值；当当前动力电池的温度达到第 一预设温度阈值时，示例性的，第一预设温度阈值为35℃，当动力电池功率小于预设功率，预设功率为动力电池最大功率的50％，动力电池功率变化率小于预设功率变化率时，预设功率变化率为10KW/s,代表在未来一段时间内，动力电池发热功率增加较小，不会造成动力电池温度快速升高，因此不用调整动力电池循环回路中电冷却装置输出的预设冷却功率、不用调节第一水泵的转速，也不用调节动力电池达到的目标温度阈值。这里需说明的是，目标温度阈值为动力电池在动力电池冷却循环后达到的理想温度值。
当当前动力电池的温度达到第一预设温度阈值时，动力电池功率小于预设功率，动力电池功率变化率大于预设功率变化率时，则调节电冷却装置输出的预设冷却功率为第一预设冷却功率，调节第一水泵为第一预设转速，调节动力电池达到的目标温度阈值为第一目标温度阈值。

其中，当当前动力电池的温度达到第一预设温度阈值时，动力电池功率大于预设功率，动力电池功率变化率小于预设功率变化率时，或者当当前动力电池的温度达到第一预设温度阈值时，动力电池功率小于预设功率，动力电池功率变化率大于预设功率变化率时，代表在未来一段时间内，动力电池发热功率增加幅度逐渐增大，会造成动力电池温度快速升高，调节电冷却装置输出第一预设冷却功率(第一预设冷却功率大于当动力电池的温度未达到第一预设温度阈值时，动力电池循环回路中电冷却装置输出的预设冷却功率)，调节第一水泵为第一预设转速(第一预设转速大于当动力电池的温度未达到第一预设温度阈值时，动力电池循环回路中第一水泵的转速)，调节动力电池为第一目标温度阈值(第一目标温度阈值小于当动力电池的温度未达到第一预设温度阈值时，动力电池达到的目标温度阈值)，可选的，第一目标温度阈值为37℃，以使动力总 成温度精确地控制在理想的范围内。
当当前动力电池的温度达到第一预设温度阈值时，动力电池功率大于预设功率，动力电池功率变化率大于预设功率变化率时，则调节电冷却装置输出的预设冷却功率为第二预设冷却功率，调节第一水泵为第二预设转速，调节动力电池达到的目标温度阈值为第二目标温度阈值；其中，第二目标温度阈值小于第一目标温度阈值；第二预设冷却功率大于第一预设冷却功率；第二预设转速大于第一预设转速。
其中，当当前动力电池的温度达到第一预设温度阈值时，动力电池功率大于预设功率，动力电池功率变化率大于预设功率变化率时，则代表在未来一段时间内，动力电池发热功率增加幅度巨大，会造成动力电池温度迅速升高，因此调节电冷却装置输出功率为第二预设冷却功率，调节第一水泵转速为第二预设转速，调节动力电池达到的目标温度阈值为第二目标温度阈值，可选的，第二目标温度阈值为35℃，立刻进入动力电池冷却模式，防止动力电池发生热失控。
示例性的，当当前动力电池的温度达到第一预设温度阈值时，动力电池温度变化率小于第一温度变化率时，可选的，第一温度变化率为0.1℃每秒，代表动力电池温度处于可控范围内，因此动力电池循环回路中电冷却装置输出的预设冷却功率、第一水泵的转速及动力电池达到的目标温度阈值为恒定值，即不调节热管理控制参数。
当当前动力电池的温度达到第一预设温度阈值时，动力电池温度变化率大于第一温度变化率时，代表动力电池温度有热失控的风险，因此调节电冷却装置输出功率为第二预设冷却功率，调节第一水泵转速为第二预设转速，调节动力电池达到的目标温度阈值为第二目标温度阈值，可选的，第二目标温度阈值为35℃，立刻进入动力电池冷却模式，防止动力电池发生热失控。
S230、当当前动力电机的温度达到第二预设温度阈值时，根据动力电机功率及动力电机功率变化率调节热管理控制参数；或者当当前动力电机的温度达 到第二预设温度阈值时，根据动力电机温度变化率调节热管理控制参数；其中，热管理控制参数包括风扇转速、第二水泵转速及动力电机达到的目标温度阈值。
示例性的，当当前动力电机的温度达到第二预设温度阈值时，动力电机功率小于预设功率，动力电机功率变化率小于预设功率变化率时，则不调节热管理控制参数。
其中，在一般的热管理控制策略中，当动力电机的温度未达到第二预设温度阈值时，动力电机循环回路中第二水泵的转速、风扇转速及动力电机达到的目标温度阈值为恒定值；当当前动力电机的温度达到第二预设温度阈值时，示例性的，第二预设温度阈值为55℃，当动力电机功率小于预设功率，预设功率为动力电机最大功率的50％，动力电机功率变化率小于预设功率变化率时，预设功率变化率为10KW/s,代表在未来一段时间内，动力电机发热功率增加较小，不会造成动力电机温度快速升高，因此不用调整动力电机循环回路中第二水泵的转速及风扇转速、也不用调节动力电机达到的目标温度阈值。
当动力电机的温度达到第二预设温度阈值时，动力电机功率小于预设功率，动力电机功率变化率大于预设功率变化率时，则调节风扇输出第一预设风扇转速，调节第二水泵为第一预设转速，调节动力电机达到的目标温度阈值为第三目标温度阈值。
当动力电机的温度达到第二预设温度阈值时，动力电机功率大于预设功率，动力电机功率变化率小于预设功率变化率时，则调节风扇输出第一预设风扇转速，调节第二水泵为第一预设转速，调节动力电机达到的目标温度阈值为第三目标温度阈值。
其中，当当前动力电机的温度达到第二预设温度阈值时，动力电机功率大于预设功率，动力电机功率变化率小于预设功率变化率时，或者当当前动力电机的温度达到第二预设温度阈值时，动力电机功率小于预设功率，动力电机功率变化率大于预设功率变化率时，代表在未来一段时间内，动力电机发热功率增加幅度逐渐增大，会造成动力电机温度快速升高，调节风扇输出第一预设风 扇转速(第一预设风扇转速大于当前动力电机的温度未达到第二预设温度阈值时，风扇的预设风扇转速)，第二水泵为第一预设转速(第一预设转速大于当前动力电机的温度未达到第二预设温度阈值时，第二水泵的预设转速)，调节动力电机为第三目标温度阈值(第三目标温度阈值小于当前动力电机的温度未达到第二预设温度阈值时，动力电机达到的目标温度阈值)，可选的，第三目标温度阈值为52℃，以使动力电机温度精确地控制在理想的范围内。
当动力电机的温度达到第二预设温度阈值时，动力电机功率大于预设功率，动力电机功率变化率大于预设功率变化率时，则调节风扇输出第二预设风扇转速，调节第二水泵为第二预设转速，调节动力电机达到的目标温度阈值为第四目标温度阈值；其中，第四目标温度阈值小于第三目标温度阈值；第二预设转速大于第一预设转速；第二预设风扇转速大于第一预设风扇转速。
其中，当当前动力电机的温度达到第二预设温度阈值时，动力电机功率大于预设功率，动力电机功率变化率大于预设功率变化率时，则代表在未来一段时间内，动力电机发热功率增加幅度巨大，会造成动力电机温度迅速升高，因此调节风扇输出第二预设风扇转速，第二水泵为第二预设转速，调节动力电机达到的目标温度阈值为第四目标温度阈值，可选的，第四目标温度阈值为50℃，立刻进入动力电机冷却模式，防止动力电机发生热失控。
示例性的，当当前动力电机的温度达到第二预设温度阈值时，动力电机温度变化率小于第二温度变化率时，则不调节热管理控制参数；其中，由于各动力总成的热特性不同，各动力总成的热容不同，一般地，由于动力电池的热容大于动力电机的热容值；即相同热量下，动力电机的温度变化大于动力电池的温度变化，因此，第二温度变化率大于第一温度变化率。其中，当动力电机温度变化率小于第二温度变化率时，可选的，第二温度变化率为0.5℃每秒，代表动力电机温度处于可控范围内，因此动力电机循环回路中风扇预设转速及第二水泵的转速、动力电机达到的目标温度阈值为恒定值。
当当前动力电机的温度达到第二预设温度阈值时，动力电机温度变化率大 于第二温度变化率时，则调节风扇输出第二预设风扇转速，调节第二水泵为第二预设转速，调节动力电机达到的目标温度阈值为第四目标温度阈值；其中，动力电机温度变化率大于第二温度变化率时，代表动力电机温度有热失控的风险，因此调节风扇输出第二预设风扇转速，调节第二水泵为第二预设转速，调节动力电机达到的目标温度阈值为第四目标温度阈值，可选的，第四目标温度阈值为50℃，立刻进入动力电机冷却模式，防止动力电机发生热失控。
本方案基于不同的动力总成的热特性，例如根据各动力总成的功率大小及各动力总成的功率变化率大小，或者根据各动力总成温度变化率的大小，提前调节热管理控制参数为不同的值，使得各动力总成温度精确地控制在理想的范围内。
