Abstract

本发明涉及一种在开动过程时用于对机动车进行速度限制的方法,其中:‑获知到沿行驶方向直接位于其前方的车辆的距离;及‑根据该距离,把机动车速度限制到预先给定的最大值上。

Description

在开动过程中用于对机动车进行速度限制的方法和装置
技术领域
本发明涉及一种在开动过程时用于对机动车进行速度限制的方法。
背景技术
当车辆车队例如在堵车之后由停止进行开动时,如果这些车辆从停止又进行开动,那么存在撞车事故的危险。尤其由于大意,例如在堵车中前方行驶的车辆的驾驶员在开动之后再次出乎意料地制动或者停车时,发生这些撞车事故。
发明内容
本发明涉及一种在开动过程时用于对机动车进行速度限制的方法,其中:
-获知到沿行驶方向直接位于其前方的车辆的距离;及
-根据该距离,把机动车速度限制到预先给定的最大值上。
因此,减小了在车辆车队中的开动过程中撞车事故的可能性。
本发明的有利设计方案,其特征在于,随着减小距离来同样地减小针对速度的最大值。
本发明的有利设计方案,其特征在于,借助不依赖于驾驶员的制动干涉和/或不依赖于驾驶员地减小机动车的驱动力矩或者马达力矩,实现防止速度提高到超过最大值或者使该速度下降到最大值。在这种情况下,尤其地可以优先(priorisieren)减小马达力矩,从而避免使制动力反作用于所施加的马达力矩上。因此,也可以首先减小马达力矩,并且仅对于这样的情况即这种减小没有导致速度小于最大值,实现额外的制动干涉。在这种情况下通过不依赖于驾驶员地干涉马达力矩和/或制动系统来超越驾驶员愿望,能够是合理的,从而避免了碰撞。
本发明的有利设计方案其特征在于,在该距离减小之后使该距离增大时,又提高该最大值。
本发明的有利设计方案其特征在于,为了在提高最大值时提高机动车速度,首先以它的程度或者强度来减小或者中断不依赖于驾驶员的制动干涉,及对于这种情况即它不充分,全部或者部分地取消不依赖于驾驶员的驱动力矩的减少。
本发明的有利设计方案其特征在于,在低于预先给定的距离时,机动车被制动直到停止。
本发明的有利设计方案其特征在于,到沿机动车行驶方向直接位于其前方的车辆的距离借助停车传感装置来获知。该设计方案被提供用于成本有利的实现方案,因为在现代车辆中大多数存在停车传感装置。这种停车传感装置大部分基于超声。
此外,本发明包括一种装置,该装置包含器件,所述器件被设计用于实施根据本发明的方法。在这种情况下,尤其是一种控制器,该控制器配备有用于实施根据本发明的方法的程序代码。
附图说明
附图包括图1。
图1中以俯视图示出了车辆车队。
具体实施方式
本发明涉及在行驶过程中减小撞车事故的可能性。为此,在图1中示出了具有沿着方向100行驶的车辆A、B和C的车队。在此,通常的做法是,首先车辆A开动,其后是车辆B,并且然后是车辆C。那么,撞车事故的危险例如是,在下一个车辆B已经正处于开动过程中之后,如果首先开动的车辆A出乎意料地或者突然地又停车。当B的驾驶员没有立即作出反应时,存在如下危险,即B撞上A。
由于绝大多数的新车辆配备有停车系统,或者其容易加装,因此存在这样的可能性,即其不仅用于停车过程,而且用于开动过程。为此,借助在B的停车系统范围内所使用的传感装置、典型为超声传感装置或者雷达传感装置,可以获知到沿开动方向邻近的车辆A的距离,并且根据该距离把机动车的速度限制到预先给定的最大值上。在这种情况下,随着减小距离来减小该最大值,因此B的驾驶员具有足够的时间用于制动过程。
