摘　　要：驾驶员精神不集中、后视镜盲区等问题,是引发交通事故的重要原因。拟提出一种将触觉反馈设备设置在方向盘上,并使用驾驶员拇指按压接触的方式进行行车预警的方式。通过在车身周围设置单点障碍区域和多点障碍区城进行模拟验证实验,实验结果表明,参与者可以通过触感迅速估计出潜在危险的区域。在单点障碍区域中,其判断准确率为81.5%,多点障碍区域中其识别准确率为84.5%,也证明了提出的触觉预警方案对用户有较强的可接受性和作用效果。Drivers’inattention and blind field of vision are the main causes of traffic accidents.In this paper,a scheme of driving early warning is proposed by setting the tactile feedback device on the steering wheel and the drivers thumb is used to press the contact for driving warning.The simulation experiment is carried out by setting single point obstacle area and multi-point obstacle area around the vehicle,the experimental results showed that the participants can quickly estimate the potential danger area through touching.In the single point obstacle area,the accuracy of judgment is 81.5%,and the recognition accuracy rate in the multi-point obstacle area is 84.5%.It also proves that the tactile warning scheme proposed in this paper has strong acceptability and effect on users.
