车辆控制方法、装置和车辆
本专利申请要求于2022年1月7日提交的中国专利申请No.CN202210017707.8的优先权。在先申请的公开内容通过整体引用并入本申请。
技术领域
本申请涉及车辆技术领域,尤其涉及一种车辆控制方法、装置和车辆。
背景技术
制动踏板和油门踏板在现有的车辆中,作为识别驾驶员驾驶意图的核心零部件,分别可以通过单侧脚踩下制动踏板以实现对车辆的制动,并通过单侧脚踩下油门踏板实现起步等。通常来说,在制动踏板被踩下的过程中以及制动踏板完全被踩下之后的情况下,会停止发动机的扭矩输出,只有在慢慢松开制动踏板的过程中,发动机的扭矩才会开始慢慢加载,当制动踏板完全松开后,车辆才会开始进入蠕行模式,开始缓慢行驶。踩下油门后,车辆识别到驾驶员的加速意图,开始按照驾驶员意图行驶。
在车辆起步时,可以通过同时操作制动踏板以及油门踏板来实现在车辆起步之前大大提高起步动力,以使得车辆能够以较大的动力快速起步,也即实现弹射起步的功能。通常,油门踏板又被称为加速踏板。其中,传统的弹射起步大都是通过加速踏板控制发动机输出较大的扭矩实现的,然而发动机输出的扭矩也是有上限的,因此只靠发动机输出的扭矩实现车辆的弹射起步,效果不佳。
技术问题

本发明的实施方式
以下描述中,为了说明而不是为了限定,提出了诸如特定系统结构、技术之类的具体细节,以便透彻理解本申请实施例。然而,本领域的技术人员应当清楚,在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中,省略对公众所周知的系统、装置、电路以及方法的详细说明,以免不必要的细节妨碍本申请的描述。
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图通过具体实施例来进行说明。
为了便于理解本申请实施例的方案,以下先简单介绍本申请实施例涉及的车辆动力系统。参见图1,该车辆动力系统可以包括发动机、发电机和驱动电机。驱动电机与车轮连接,发动机通过齿轮组与发电机连接,发动机的输出轴端再通过离合器与车轮连接。在离合器为吸合状态时,发动机和驱动电机共同驱动车轮;在离合器为断开状态时,由驱动电机驱动车轮。
在车辆起步时,为了使得车辆能够以较大的动力起步,可以通过驱动电机的输出扭矩和发动机的输出扭矩两者的共同作用,驱动车辆以较大的扭矩起步。然而在起步之前,发动机的曲轴端还不能向车轮施加扭矩,否则会导致车辆发动机熄火,此时可以在调整发动机的输出扭矩的同时调整发电机的输出扭矩,使得发动机的输出扭矩与发电机的输出扭矩相互平衡,来达到发动机的曲轴端的输出扭矩为零的目的。
具体的,可以控制发动机的转速为预设转速,并控制离合器的状态为滑磨状态。之后,同步提升发动机的输出扭矩和发电机的输出扭矩,使得发动机的输出扭矩和发电机的输出扭矩达到动态实时平衡的效果。在检测到起步指令(制动踏板开度小于开度阈值)时,控制发电机的输出扭矩按照梯度减小的方式退出,然后可以通过驱动电机的输出扭矩和发动机的输出扭矩驱动车辆起步。
以下结合图1,对本申请实施例中提供的车辆控制方法进行详述。
参见图2,其示出了本申请实施例提供的车辆控制方法的实现流程图,详述如下:
步骤201,响应起步蓄力指令,确定车辆的所需输出扭矩。
示例性的,上述起步是指车辆从静止状态到运动状态的转变,可以基于车辆工况确定车辆的所需输出扭矩,车辆工况包含加速踏板深度。上述所需输出扭矩与加速踏板开度呈正相关关系,即加速踏板开度越大,对应的所需输出扭矩越大;加速踏板开度越小,对应的所需输出扭矩越小。
上述所需输出扭矩包括发动机的第一输出扭矩和驱动电机的第二输出扭矩,第一输出扭矩和第二输出扭矩分别是指在当前状态下、即在接收到起步蓄力指令的状态下,车辆控制器为发动机分配的输出扭矩和为驱动电机分配的输出扭矩。其中,第一输出扭矩可以小于或等于发动机能够提供的最大扭矩,第二输出扭矩可以小于或等于驱动电机能够提供的最大扭矩,且第一输出扭矩和第二输出扭矩之和为上述所需输出扭矩。
示例性的,上述基于车辆工况确定车辆的所需输出扭矩,可以包括:通过预设数据表确定加速踏板深度对应的所需输出扭矩。其中,预设数据表可以包含加速踏板深度和所需输出扭矩之间的对应关系,且预设数据表可以通过预先标定得到,例如,通过模拟实验检测、记录和验证加速踏板深度和所需输出扭矩的变化规律,进而得到加速踏板深度和所需输出扭矩之间的对应关系,或者,也可以通过预先计算设计加速踏板深度和所需输出扭矩之间的对应关系,本实施例中,预先标定的方式有多种,本领域技术人员可以知晓,对此不作详细说明。
其中,在得到所需输出扭矩之后,可以将所需输出扭矩与车辆能够提供的可用总扭矩进行比较,若所需输出扭矩小于或等于可用总扭矩,则可以按照上述所需输出扭矩为车辆起步进行蓄力;若所需输出扭矩大于可用总扭矩,则说明车辆所需扭矩过大,车辆无法提供,则可以将所需输出扭矩的数值降低到可用总扭矩对应的数值及以下,为车辆起步进行蓄力。
一些实施例中,可用总扭矩可以为车辆的动力系统当前能够提供的扭矩,即可以基于发动机的第一可用扭矩和驱动电机的第二可用扭矩确定可用总扭矩。
具体的,第一可用扭矩为发动机当前能够提供的扭矩,第二可用扭矩为驱动电机当前能够提供的扭矩,可用总扭矩为第一可用扭矩和第二可用扭矩之和。而第二可用扭矩可以基于驱动电机的放电功率和转速确定,第一可用扭矩可以为发动机反馈的数值。其中,第二输出扭矩可以小于或等于第二可用扭矩,第一输出扭矩可以小于或等于第一可用扭矩。
例如,可用总扭矩可以为第一可用扭矩 Tq engine 和第二可用扭矩 Tq motor 之和,第二可用扭矩可以根据公式 Tq motor = a· P/n计算得到, a为预设系数, P为驱动电机的放电功率, n为驱动电机的转速, a可以为9550。
另外,在根据公式 Tq motor = a· P/n计算得到第二可用扭矩 Tq motor 之后,可以将第二可用扭矩 Tq motor 与驱动电机的最大扭矩进行比较,以防止计算得出的第二可用扭矩 Tq motor 大于驱动电机所能够提供的最大扭矩,而导致驱动电机无法提供第二可用扭矩对应的扭矩。其中,驱动电机的最大扭矩可以为驱动电机标定的能够输出的最大扭矩。
若第二可用扭矩 Tq motor 小于或等于驱动电机的最大扭矩,则根据第二可用扭矩 Tq motor 和第一可用扭矩 Tq engine 之和确定可用总扭矩。若第二可用扭矩 Tq motor 大于驱动电机的最大扭矩,则根据驱动电机的最大扭矩和第一可用扭矩 Tq engine 之和确定可用总扭矩。
由于驱动电机响应较快,相对于发动机能够快速输出给定扭矩,因此可以先根据驱动电机的可用扭矩为驱动电机分配对应的扭矩,再将剩余扭矩分配给发动机。
例如,对于所需输出扭矩 T req 可以先分配给驱动电机按照第二可用扭矩 Tq motor 输出,此时第二输出扭矩等于第二可用扭矩 Tq motor 。之后,向发动机分配剩余的扭矩,即所需输出扭矩 T req 减去第二可用扭矩 Tq motor 得到的扭矩。
又例如,对于所需输出扭矩 T req 可以先分配给驱动电机按照小于第二可用扭矩 Tq motor 的某个扭矩 T’q motor 输出,之后向发动机分配剩余的扭矩,即所需输出扭矩 T req 减去扭矩 T’q motor 得到的扭矩。
一种场景中,起步蓄力指令可以基于制动踏板和加速踏板触发。例如,若制动踏板开度大于或等于第一开度阈值,加速踏板开度大于或等于第二开度阈值,则车辆控制器生成起步蓄力指令。
作为举例,第一开度阈值可以为制动踏板的最大开度对应的阈值,第二开度阈值可以为加速踏板的最大开度对应的阈值。或者,第一开度阈值可以为80%,第二开度阈值可以为70%。需要说明的是,以上对第一开度阈值和第二开度阈值的说明仅为示例性的,不以此为限,本领域技术人员可以根据需要设置其他数值的第一开度阈值和第二开度阈值。
一些实施例中,在响应起步蓄力指令之后,可以先检测车辆状态是否满足预设条件,该预设条件包括用于表征驱动电机能够为车辆起步提供足够大的扭矩,以及ESP系统没有开启和安全带系紧等信息。具体的,该车辆状态可以包括电池SOC(State Of Charge,荷电状态)、电池包温度、电池包放电功率、驱动电机温度、ESP(Electronic Stability Program,车身电子稳定系统)状态和安全带状态。
若电池SOC大于SOC阈值,电池包温度位于第一预设范围,电池包放电功率大于功率阈值,驱动电机温度位于第二预设范围,ESP状态为关闭且安全带状态为系紧,则执行上述基于车辆工况确定车辆的所需输出扭矩的步骤。
其中,电池SOC能够反映电池的剩余容量,在车辆起步时需要用到驱动电机的电池包放电以提供扭矩,因此需要预先检测电池SOC是否大于SOC阈值,若电池SOC小于SOC阈值,则会导致驱动电机能够提供的扭矩变小,起步效果较差。
电池包温度能够反映电池的状态,若电池包温度过高或过低(没有位于第一预设范围内),则会影响电池包的参数性能,使得电池包的性能降低,而在车辆起步时需要用到驱动电机的电池包放电以提供扭矩,这样会导致驱动电机能够提供的扭矩变小,起步效果较差。其中,第一预设范围为不影响电池包的参数性能的温度范围。
电池包放电功率能够反映电池包的放电能力,在车辆起步时需要用到驱动电机的电池包放电以提供扭矩,若电池包放电功率小于功率阈值,则会导致驱动电机能够提供的扭矩变小,起步效果较差。其中,第一预设范围为不影响电池包的参数性能的温度范围。
驱动电机温度能够反映驱动电机的性能,若驱动电机温度过高或过低(没有位于第二预设范围内),则会影响驱动电机的性能,使得驱动电机的输出扭矩减小,而在车辆起步时需要用到驱动电机的电池包放电以提供扭矩,这样可能导致驱动电机能够提供的扭矩变小,起步效果较差。其中,第二预设范围为不影响驱动电机的性能的温度范围。
对于ESP状态,由于车辆起步时扭矩较大,可能出现车轮打滑的现象,若ESP状态为开启,则ESP系统会介入以降低扭矩进而保持车身的稳定,这同样也会导致车辆起步时的动力变小,导致起步效果变差。
安全带状态能够表征驾驶员和车上乘客是否已经系紧安全带,若安全带状态为安全带系紧,则可以进行弹射起步;若安全带未系紧,则可以提醒用户系紧安全带之后进行弹射起步,或不进行弹射起步(例如可以停止执行后续步骤)。
步骤202,控制驱动电机的输出扭矩为第二输出扭矩。
其中,在确定车辆的所需输出扭矩之后,由于驱动电机响应较快,相对于发动机能够快速输出给定扭矩,因此可以先根据驱动电机的最大扭矩为驱动电机分配对应的扭矩,再将剩余扭矩分配给发动机。
例如,对于所需输出扭矩 T req 可以先分配给驱动电机按照第二可用扭矩 Tq motor 输出,之后向发动机分配剩余的扭矩,即所需输出扭矩 T req 减去第二可用扭矩 Tq motor 得到的扭矩。
又例如,对于所需输出扭矩 T req 可以先分配给驱动电机按照小于第二可用扭矩 Tq motor 的某个扭矩 T’q motor 输出,之后向发动机分配剩余的扭矩,即所需输出扭矩 T req 减去扭矩 T’q motor 得到的扭矩。
步骤203,控制发动机的输出扭矩为第一输出扭矩,控制发电机的输出扭矩为第三输出扭矩。
其中,发电机与发动机通过行星齿轮连接,且第三输出扭矩与第一输出扭矩相互平衡,使得发动机的曲轴端的输出扭矩为零。并且,第二输出扭矩与第一输出扭矩之和为所需输出扭矩。
由于在起步之前,发动机的曲轴端还不能向车轮施加扭矩,否则会导致车辆行驶或发动机熄火,因此本申请中在将发动机的输出扭矩调整为第一输出扭矩的同时,还控制发电机输出第三输出扭矩,使得第三输出扭矩与第一输出扭矩相互平衡,来达到发动机的曲轴端的输出扭矩为零的目的。
一些实施例中,步骤203的实现过程可以包括:控制发动机的转速为预设转速;向发动机和发电机发出扭矩干预指令,并控制离合器的状态为滑磨状态;响应扭矩干预指令,同步提升发动机的输出扭矩和发电机的输出扭矩,使得发动机的输出扭矩到达第一输出扭矩,发电机的输出扭矩到达第三输出扭矩。
具体的,在弹射起步之前需要车辆在静止状态输出扭矩,才能够达到弹射起步的效果。驱动电机可以直接响应扭矩,而发动机的曲轴端在车辆静止时,如果发动机响应扭矩则无法闭合离合器。此时,HCU(Hybrid Control Unit,混合动力控制单元)可以将发动机转速控制在1350rpm左右,然后发出扭矩干预指令以控制发动机的曲轴端的输出扭矩为0,同时控制离合器至滑磨状态。此时进入直驱模式,请求发动机的输出扭矩为 T req - Tq motor ,请求发电机的输出扭矩为0-速比*( T req - Tq motor ),之后开始同步提升发动机的输出扭矩和发电机的输出扭矩,从而保证在结合离合器时发动机的曲轴端的输出扭矩为0。上述速比基于发动机和发电机之间的齿轮组确定,为本领域技术人员熟知技术,对此不作详细说明。
步骤204,响应起步指令,控制发电机的第三输出扭矩按照预设方式退出,基于第二输出扭矩和发动机的曲轴端的输出扭矩驱动车辆起步。
其中,起步指令可以为制动踏板开度为零触发的,即在检测到制动踏板开度小于第三开度阈值时,控制发电机的第三输出扭矩按照梯度减小的方式退出。
在发电机的第三输出扭矩按照梯度减小的方式退出的过程中(这一过程时间较短,通常只有2秒左右),发动机的曲轴端的输出扭矩在短时间内逐渐变大,车辆的动力系统通过驱动电机输出的第二输出扭矩和发动机的曲轴端的输出扭矩驱动车辆实现弹射起步。
另外,在车辆开始运动以后,车辆的所需输出扭矩可以基于加速踏板深度和车辆行驶速度共同确定。例如,可以根据加速踏板深度和车辆行驶速度,通过预设数据表确定对应的所需输出扭矩。其中,预设数据表可以包含加速踏板深度、车辆行驶速度和所需输出扭矩之间的对应关系。同样地,该预设数据表可以通过预先标定得到,该预先标定方式与前述预先标定方式相似,在此不再赘述。
上述车辆控制方法,在车辆起步之前响应起步蓄力指令进行扭矩蓄力,控制驱动电机的输出扭矩为第二输出扭矩,发动机的输出扭矩为第一输出扭矩,通过驱动电机和发动机进行扭矩蓄力来增大起步的动力。由于在起步之前,发动机的曲轴端还不能向车轮施加扭矩,否则会导致车辆行驶或发动机熄火,因此本申请中在将发动机的输出扭矩调整为第一输出扭矩的基础上,还控制发电机输出第三输出扭矩,使得第三输出扭矩与第一输出扭矩相互平衡,来达到发动机的曲轴端的输出扭矩为零的目的。之后,在接收到起步指令后,控制发电机的第三输出扭矩按照预设方式退出,就可以基于第二输出扭矩和发动机的曲轴端的输出扭矩两者的共同作用,驱动车辆以较大的扭矩起步。
应理解,上述实施例中各步骤的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
