With the advancement of automatic navigation, navigation control has become an indispensable core technology in the movement of unmanned vehicles. In particular, research on navigation control in outdoor wooded environments, which are more complex, less controlled, and more unpredictable than indoor environments, has received widespread attention. To realize the movement control and obstacle avoidance of unmanned vehicles in unknown environments, in this study, we use light detection and ranging (LiDAR) sensors to sense the surrounding environment. By plane meshing the point cloud reflected from LiDAR, we can instantly establish feasible regions. At the same time, using the artificial potential field algorithm, a stable obstacle avoidance and navigation path is planned for use in an unknown environment. In an actual woods navigation experiment to evaluate our proposed LiDAR detection method, we used an independently developed unmanned vehicle with Ackermann steering geometry. Experimental results indicate that the proposed method can effectively detect obstacles. The accuracy requirement is within 30 cm from the navigation target, and the experimental results show that the average navigation success rate of the proposed method is as high as 85%. The experimental results demonstrate that the system can stably and safely navigate in scenarios with different unknown environments.
随着自动导航技术的发展,导航控制已成为无人驾驶车辆行驶过程中不可或缺的核心技术。与室内环境相比,室外林木环境更加复杂、可控性更差、不可预知性更强,因此室外林木环境下的导航控制研究尤其受到广泛关注。为了实现无人车在未知环境中的运动控制和避障,本研究使用光探测与测距(LiDAR)传感器来感知周围环境。通过对激光雷达反射的点云进行平面网格划分,我们可以立即建立可行区域。同时,利用人工势场算法,规划出在未知环境中使用的稳定避障和导航路径。在实际的树林导航实验中,我们使用了自主研发的具有阿克曼转向几何结构的无人车,对我们提出的激光雷达检测方法进行了评估。实验结果表明,所提出的方法能够有效探测障碍物。实验结果表明,该方法的平均导航成功率高达 85%。实验结果表明,该系统可以在不同的未知环境中稳定、安全地导航。

Design and Fabrication of a Built-in Tire Sensor for Green Energy Saving 设计和制造用于绿色节能的内置式轮胎传感器

The environmental impact stemming from scrapped tires has indirectly affected ecological sustainability. One effective approach to mitigate the impact of tires on the environment is to enhance the wear resistance of tires. However, balancing wear resistance and meeting performance control requirements can be challenging. Therefore, improving drivers’ driving habits can be regarded as another way of prolonging tire usage. In this study, we aim to develop a suitable sensor for tires that can detect tire overcontrol to reduce the possibility of excessive wear. However, commercially available sensors are designed for use within the interior of tires and are commonly used rigid parts and components to detect microstrains. Hence, the primary objective of this study is to develop and design a special strain gauge for tires while discussing and recording the tire strain characteristics during tire operation and after the sensor is embedded into the tire. This approach helps in finding the critical value of tire overcontrol. The findings of this study can be integrated into in-car systems to remind drivers, prompting them to reduce their control to extend the service life of tires, ultimately reducing the environmental impact associated with excessive tire replacements.
报废轮胎对环境造成的影响间接影响了生态的可持续性。减轻轮胎对环境影响的一个有效方法是提高轮胎的耐磨性。然而,平衡耐磨性和满足性能控制要求是一项挑战。因此,改善驾驶员的驾驶习惯可被视为延长轮胎使用寿命的另一种方法。在这项研究中,我们旨在开发一种适用于轮胎的传感器,它可以检测轮胎的过度控制,以减少过度磨损的可能性。然而,市面上的传感器是专为轮胎内部设计的,通常用于检测微小应变的刚性部件和组件。因此,本研究的主要目标是开发和设计一种轮胎专用应变计,同时讨论和记录轮胎运行期间和传感器嵌入轮胎后的应变特性。这种方法有助于找到轮胎过度控制的临界值。这项研究的结果可以集成到车载系统中,以提醒驾驶员,促使他们减少对轮胎的控制,从而延长轮胎的使用寿命,最终减少因过度更换轮胎而对环境造成的影响。
