这些优势使 messtec drives automation 商业期刊的编辑人员和专业观众深信不疑: CLSx获得了传感器领域的Messtec & Sensor Masters奖。
评估驾驶员辅助系统和自动驾驶
当操作具有驾驶员辅助系统,高级驾驶员辅助系统(ADAS)和自动驾驶功能的车辆时,以下仍然适用:驾驶员负责并且必须能够始终控制他的车辆。这意味着ADAS系统(如车道保持和车道变换辅助系统)的转向操纵必须能够随时由驾驶员手动影响。为此所需的转向扭矩 - 也称为过压扭矩 - 不得超过3 Nm。 CLSx 方向盘转向力转角传感器,是研究这种过压扭矩的理想选择,因为即使在这个小的测量范围内也能提供高分辨率的结果。保留了具有所有功能的原始方向盘,包括安全气囊和电容式手动检测。由于尺寸非常紧凑且重量轻,传感器具有低质量惯性扭矩。此外,它以特别低的摩擦力运行。所有这些确保了安装的转向传感器几乎不会对生产车辆的转向系统产生任何影响。因此,转向行为保持与生产车辆的相同。
