汽车的驾驶模式包括双踏板驾驶模式和单踏板驾驶模式,其中,双踏板驾驶模式为相关技术中的驾驶模式,其通过制动踏板实现车辆制动,油门踏板实现车辆驱动;单踏板驾驶模式为通过油门踏板一个踏板进行车辆制动和车辆驱动。
可选地,参照图2,步骤1包括:
步骤11,确定汽车的单踏板开关的工作状态;
步骤12,获取汽车的单踏板开关的工作状态为开启状态时的当前挡位和当前故障状态;
步骤13,在所述当前挡位为预定挡位且所述当前故障状态为未故障状态时,确定汽车的驾驶模式为单踏板驾驶模式。
汽车的单踏板开关的工作状态为单踏板开关处于使能状态时的工作状态。
单踏板开关的工作状态为开启状态是指单踏板开关处于使能状态时,用户对单踏板开关进行操作后的状态。在单踏板开关处于不使能状态时,单踏板开关呈灰色模式,此时,用户无法对单踏板开关进行操作;在单踏板开关处于使能状态时,此时,单踏板开关呈红色模式,此时,用户可以对单踏板开关执行操作,用户在首次按压单踏板开关后,即表明用户希望开启单踏板驾驶模式,此时,单踏板开关的工作状态为开启状态。
为了保证在单踏板驾驶模式下车辆的安全行驶,要求车辆进入单踏板驾驶模式前,车辆的各个运行参数正常,未出现异常。
可选地,参照图3,步骤11包括:
步骤111,获取汽车的当前挡位和制动踏板开度;
步骤112,在汽车的当前挡位为预定挡位且所述制动踏板开度大于预设开度值时,确定汽车的单踏板开关处于使能状态;
步骤113,判断是否接收到单踏板开关处于使能状态时用户对单踏板开关进行操作的处理信号;
步骤114,若接收到,则确定汽车的单踏板开关的工作状态为开启状态。
在本公开实施例中,出厂设置的汽车,其单踏板开关的使能状态默认为不使能状态。在根据步骤112确定出汽车的单踏板开关处于可使能状态后,整车控制器通过控制器局域网络(Controller Area Network,CAN)报文的形式向汽车的娱乐主机单元(Entertainment Head Unit,EHU)发送单踏板开关使能信号,EHU根据接收到的CAN报文的报文标志位(例如:报文标志位为1,对应使能状态;报文标志位为0,对应不使能状态),确定是否控制单踏板开关处于使能状态。EHU根据接收的CAN报文的报文标志位控制单踏 板开关处于使能状态后,EHU向整车控制器反馈单踏板开关处于使能状态时用户对单踏板开关进行操作的处理信号(即单踏板开关的工作状态为开启状态)。
若EHU根据整车控制器发送的CAN报文中确定出整车控制器下发的命令为控制单踏板开关为不使能状态时,EHU则根据自身存储的汽车上次下电时的单踏板开关的工作状态控制单踏板开关,即,汽车前次下电时,EHU存储的单踏板开关的工作状态为开启状态,则此时控制单踏板开关处于开启状态;汽车前次下电时,EHU存储的单踏板开关的工作状态为关闭状态,则此时控制单踏板开关处于关闭状态。
步骤2,获取汽车的驾驶模式为单踏板驾驶模式时的油门踏板开度和电机转速。
步骤3,根据所述油门踏板开度和所述电机转速,确定电机的初始输出扭矩。
可选地,参照图4,步骤3包括:
步骤31,确定汽车的蠕行功能按键的工作状态;
步骤32,在所述蠕行功能按键的工作状态为开启状态时,根据所述油门踏板开度、所述电机转速,按照油门踏板开度、电机转速和电机的初始输出扭矩之间的第一预定对应关系表格,确定电机的初始输出扭矩;或

其中,在所述第一预定对应关系表格中,当所述油门踏板开度和所述电机转速均为零时,所述初始输出扭矩不为零;
在所述第二预定对应关系表格中,当所述油门踏板开度和所述电机转速均为零时,所述初始输出扭矩为零。
在第一预定对应关系表格中,包括有:驾驶员踩油门踏板时,每一油门踏板开度和每一电机转速对应的电机的初始输出扭矩;和驾驶员松油门踏板时,每一油门踏板开度和每一电机转速对应的电机的初始输出扭矩。

在驾驶员踩油门踏板时,根据第一预定对应关系表格或第二预定对应关系表格中的数据确定出的电机的初始输出扭矩为驱动扭矩,该驱动扭矩用于实现对汽车的加速。
在驾驶员松油门踏板时,根据油门踏板开度的具体数值的不同,汽车可能处于加速状态、滑行状态或者减速状态。在本公开实施例中,将油门踏板开度划分为三个区间:加速区、滑行区和减速区,其中,加速区的油门踏板开度大于滑行区的油门踏板开度,滑行区的油门踏板开度大于减速区的油门踏板开度。在油门踏板开度处于加速区时,根据第一预定对应关系表格或第二预定对应关系表格中的数据确定出的电机的初始输出扭矩为驱动扭矩,该驱动扭矩用于实现对汽车的加速;在油门踏板开度处于滑行区时,根据第一预定对应关系表格或第二预定对应关系表格中的数据确定出的电机的初始输出扭矩为零,此时,电机不进行扭矩输出,车辆进入滑行状态;在油门踏板开度处于减速区时,根据电机转速数值的不同,从第一预定对应关系表格或第二预定对应关系表格中的数据确定出的电机的初始输出扭矩可能为:制动扭矩或驱动扭矩。
可选地,所述第一预定对应关系表格和所述第二预定对应关系表格均为至少两种;其中,不同第一预定对应关系表格中,相同油门踏板开度和相同电机转速对应的电机的初始输出扭矩的数值不同;不同第二预定对应关系表格中,相同油门踏板开度和相同电机转速对应的电机的初始输出扭矩的数值不同。
具体地,第一预定对应关系表格和第二预定对应关系表格均为三种,每一种第一预定对应关系表格和第二预定对应关系表格对应于一种制动强度,根据用户选择的制动强度的不同,选取对应的预定关系表格来执行步骤3。
步骤4,对所述电机的初始输出扭矩进行扭矩限值处理,获得进行扭矩限值处理后的扭矩,并输出。
可选地,参照图5,步骤4包括:
步骤41,判断所述电机的初始输出扭矩是否大于电机的最大允许输出扭 矩;
步骤42,若大于,则将所述最大允许输出扭矩确定为扭矩限值处理后获得的扭矩;
步骤43,若小于或等于,则将所述电机的初始输出扭矩确定为扭矩限值处理后获得的扭矩。
在根据步骤3中确定的电机的初始输出扭矩为制动扭矩时,步骤41中的最大允许输出扭矩对应的为最大允许制动输出扭矩;在步骤3中确定的电机的初始输出扭矩为驱动扭矩时,步骤41中的最大允许输出扭矩对应的为最大允许驱动输出扭矩。
可选地,所述方法还包括:
步骤5,获取汽车的制动减速度;
步骤6,在所述制动减速度大于预定减速度值时,控制车辆制动灯开启。
对于汽车的制动减速度可以通过汽车上设置的加速度传感器进行采集。
步骤5和步骤6的设置,是为了在单踏板驾驶模式时,在制动扭矩过大时,向后方车辆驾驶员提示,车辆处于制动状态,提示后方车辆驾驶员注意行驶。
通过本公开实施例提供的电机的输出扭矩控制方法,主要达到了以下效果①减轻驾驶员疲劳度,当在城市常规路况行车时,驾驶员只需控制油门踏板,不用来回切换油门踏板与制动踏板,减轻疲劳;②降低制动系统损耗,当在城市常规路况行车时,车辆完全可以采用电机制动代替相关技术中的液压制动系统,从而降低液压制动系统损耗;③提高车辆续驶里程,车辆处于单踏板驾驶模式功能状态下,可以提高整车能量利用率,从而提升续驶里程。④整车配置要求低,本公开上述方法的实现,只需要通过VCU和EHU的信息交互便可实现。
综上,本公开上述方法实现了通过一个制动踏板使得汽车处于加速状态或者制动状态,提高了驾驶员驾驶舒适性能,且,能够保证车辆的安全行驶。
