紧急情况下驾驶员能否做出准确、及时的判断和操作,对于防止交通事故具有重要的现实意义。为 保证车辆行驶安全,有必要对车辆行驶中紧急度做出判断,并给出相应的控制算法。首先提出基于相对距离、 车速和驾驶员基本特征的车辆行驶中紧急度,同时给出基于模糊推理的车辆行驶控制算法,并对其进行了仿真 运算。仿真结果表明:情况越紧急,驾驶员会越快地采用最大制动减速度;驾驶员基本特征对制动操作的影响 明显。总之,通过模糊推理控制后车的制动减速度,能实现后车的行车安全。

Stochastic dynamic job shop scheduling problem with consideration of sequence-dependent setup times are among the most difficult classes of scheduling problems. This paper assesses the performance of nine dispatching rules in such shop from makespan, mean flow time, maximum flow time, mean tardiness, maximum tardiness, number of tardy jobs, total setups and mean setup time performance measures viewpoint. A discrete event simulation model of a stochastic dynamic job shop manufacturing system is developed for investigation purpose. Nine dispatching rules identified from literature are incorporated in the simulation model. The simulation experiments are conducted under due date tightness factor of 3, shop utilization percentage of 90 % and setup times less than processing times. Results indicate that shortest setup time (SIMSET) rule provides the best performance for mean flow time and number of tardy jobs measures. The job with similar setup and modified earliest due date (JMEDD) rule provides the best performance for makespan, maximum flow time, mean tardiness, maximum tardiness, total setups and mean setup time measures.
关键词: scheduling stochastic dynamic job shop sequence-dependent setup times dispatching rule simulation

不同智能驾驶试验平台的传感器型号、数量、安装位置各不相同,导致传感器信息处理模块也各不相同;不同驾驶地图,其提供信息的粒度也没有固定标准,由此构成的智能驾驶系统软件模块的数量、接口各不相同。基于以驾驶脑为核心的智能驾驶车辆软件与硬件架构,决策模块将不直接与传感器信息处理模块发生关联,通过驾驶认知的形式化语言,将驾驶认知形式化,由驾驶脑认知形成决策。驾驶认知的形式化降低了传感器数量、类型、安装位置的变化对整个软件架构的影响,使得软件架构可以在不同传感器配置车辆平台上方便地移植。

A piezoelectric actuated prestage driver of hydraulic servo valves for the low-frequency response of electrohydraulic servo valve electromagnetic prestage driver was presented. The new driver was driven by piezoelectric multilayer actuators. The displacement of a piezoelectric multilayer actuator was amplified by a flexure-hinged amplifier based on the principles of triangle amplification. Static and dynamic characteristics were tested on the model machine. The characteristics of good linearity, high resolution, and high-frequency response were approved. The natural frequency reached 1.201 kHz using finite element analysis, and the practice measurement result was 1 kHz.

自动驾驶地图作为实现汽车自动驾驶的关键基础设施,对于推动我国自动驾驶领域的商业化开发至关重要。现阶段,我国受地图测绘、应用和监管等相关法律法规的制度掣肘,在自动驾驶地图的产业化进程方面相对滞后。为此,本文着重分析了我国在自动驾驶地图开发、应用和管理中面临的主要政策法规问题:自动驾驶地图是否需加密的问题、自动驾驶地图部分地理信息表达受限的问题、自动驾驶地图地理信息采集资质和审图流程的问题、自动驾驶地图事故责任和保险问题、自动驾驶地图相关测试规范和测试场景问题。同时结合国内外自动驾驶领域的发展趋势,给出加快我国自动驾驶汽车开发和商业化进程的四点建议:制定自动驾驶地图管理模式、允许自动驾驶地图应用试点及有序开放、适当放开企业权限及优化审核流程、建立国家级自动驾驶地图平台。
