steering interferes with lateral acceleration while cornering. Depending
on the steering ratio and the cruising speed, we identify that the readiness
of a driver to compensate lateral forces exhibits counterintuitive charac-

resolution pressure sensor integrated invisibly and unobtrusively into the
fabric of the driver seat has been developed. Sensor data, collected by two
32x32 pressure sensor arrays (seat- and backrest), is classified according
to features defined based on cornering driving situations. Experimen-
tal results verify an increased readiness to compensate lateral acceler-
ation with increasing driving speed, but only beyond a certain driver
specific ”break even” point. Above intelligent driver assistance, e.g. to
improve steering precision, to reduce or avoid over-steer or under-steer,
or to proactively notify electronic stability control (ESC), our results
also encourage for new modalities in driver-to-car and car-to-roadside
interaction.

智能车辆操纵:转弯时的车身姿态与控制
摘要：汽车的操纵与控制是智能驾驶辅助系统的一个基本组成部分，也是即将产生的所谓“智能车辆”的基本模块。车辆的操纵受到如技术性因素（包括引擎、刹车、轮胎、车轮、转向等）、环境因素（包括道路状况、气象、交通等）和人为因素（包括驾驶员的专注性、反应、敏捷性等）及它们之间相互关系的影响。在本文中，我们将要研究驾驶员在转弯时如何努力摆脱横向加速度的影响完成精确转向。根据转向传动比和速度的大小，我们发现司机对抗侧向力是一种直觉的表现。通过将一种集成的高灵敏度压力传感器置于司机座位可以对司机的身体姿态进行识别。两个32X32压力传感器阵列收集到的数据根据不同转弯情况的不同特征进行分类。实验结果验证了：只有在超过某一个特定的平衡点后，越高的行驶速度司机对抗侧向力的准备越充分。上述的智能驾驶辅助，是为了提高例如转向精确性，减少或避免过度转向或转向不足或主动通知电子稳定控制，我们的研究结果还鼓励司机与车辆及车辆与道路之间的新型互动模式。
