Description
技术领域
本发明涉及一种用于控制自动变速器的方法。
背景技术
很多年以来已经在机动车中已知自动变速器,借助电子控制器自动驱控所述自动变速器,尤其是用以挂上一定的挡。在此,给驾驶员提供换档杆,通过该换档杆至少可手动地预选一个倒挡R、一个空挡位置N和一个前进行驶位置D。近期以来,本申请人提供了这种具有电子换档杆的自动变速器(BMW Steptronic)。本发明由此出发。
发明内容
本发明的目的在于,即使在极端行驶工况下也辅助驾驶员。
按照本发明,所述目的通过独立权利要求1的技术方案得以解决。从属权利要求是本发明有利的进一步改进方案。
本发明涉及一种用于在机动车中在离心转弯期间借助电子控制器控制自动变速器的方法,在所述离心转弯时机动车在挂上倒挡的情况下首先以高于预定阈值(例如20km/h)的或在预定范围(例如20km/h<v<40km/h)之内的车速直线行驶,然后获得定义的转向脉冲,通过所述转向脉冲开启转动运动(漂移)。在超过定义的转角(例如110°)时,将自动变速器自动地从倒挡切换到空挡位置。
优选地,在本发明的一种进一步改进方案中,在识别到转动运动结束时(例如经由车轮转速传感器在达到例如为180°的最大转角之后),将自动变速器自动地从空挡位置切换到前进行驶位置。
对于按照本发明的用于在机动车中在离心转弯期间控制自动变速器的控制装置,在所述离心转弯时机动车在挂上倒挡的情况下首先以高于预定阈值的或在预定范围之内的车速直线行驶,然后获得定义的转向脉冲,通过所述转向脉冲开启转动运动,其中,所述控制装置包括电子控制器,所述电子控制器总体上用于控制机动车中的自动变速器,其中,在超过定义的转角时,所述电子控制器的功能模块能将自动变速器自动地从倒挡切换到空挡位置。
优选地,在识别到转动运动结束时,所述电子控制器的功能模块能将自动变速器自动地从空挡位置切换到前进行驶位置。
附图说明
依据附图在一种实施例的范围内详细阐述本发明。
图1示出一种行驶工况的示意图,在该行驶工况中应用按照本发明的方法。
具体实施方式
在附图中示出一种行驶工况,在该行驶工况中机动车1的驾驶员在倒车行驶位置中或者说在倒挡R中以约30km/h的车速直线行驶并且在时刻t0突然转弯,从而机动车直至时刻t2绕自身轴线转动了约180°。在也称为离心转弯的行驶工况期间,按照本发明经由在控制器2中的识别功能与驾驶员对换档杆的操纵无关地将自动变速器自动地从R经由空挡位置N控制到(前进)行驶位置D。这以电子换档杆为前提条件,通过该电子换档杆不执行对自动变速器的直接的液压干预。
识别功能借助常见的传感器(例如方向盘角度传感器、车轮转速传感器、横摆角度传感器)尤其是检测在倒车行驶期间是否达到了预定的最小速度(例如20km/h),是否达到了转向脉冲R_LW、尤其是转向角LW的短且相对强的变化,以及通过转向脉冲R_LW从漂移开始起关于转角DW是否达到了预定的阈值S_DW。
下面依据关于时间t的所绘出的曲线详细阐述在所示行驶工况中的各个步骤:
1.机动车1从转角DW为0°的初始位置在挂上倒挡R的情况下首先以高于预定阈值(例如20km/h)的或在预定范围(例如20km/h<v<40km/h)之内的车速v——在这里以30km/h直线行驶。
2.驾驶员在时刻t0产生定义的转向脉冲R_LW,通过所述转向脉冲开启转动运动(漂移)。
3.按照本发明,在超过定义的转角S_DW(例如110°)时,将自动变速器借助控制器2自动地从倒挡R切换到空挡位置N。
4.在识别到转动运动结束时(例如经由车轮转速传感器在达到例如为180°的最大转角之后),将自动变速器自动地从空挡位置N切换到前进行驶位置D。
利用本发明创造了一种安全且快速的并且具有接下去舒适的继续行驶可能性的离心转弯。
