LRW Engineering is the leading UK emissions & OBD calibration specialist, asupplier to the UK’s largest automotive manufacturers including Jaguar LandRover and Bentley Motors.

拥有超过15年的汽车OBD符合性项目交付经验,贯穿项目伊始至项目认证阶段;所有已交付客户的OBD诊断标定项目包含了柴油机、汽油机、混动汽车应用,且面向多个不同市场,包括欧6、美国CARB/EPA、中国;负责所有法规要求的符合性以及所有内部流程要求符合性
We have over 15 years experience delivering OBD compliant automotive projects fromthe start of the project through to certification. We have delivered OBD diagnostic calibration across diesel, gasoline and hybrid electric vehicle applications, delivering to many different markets including EU6, CARB/EPA and China, responsible for meeting all regulations and all internal process requirements.

位于英格兰东萨克斯郡的郊外地区;提供测试设备及测试场地,可满足原型车辆安全存放,可方便接触到全兼容的4WD驱动底盘测功机排放测试系统;还可接触到不排放的4WD驱动底盘测功机系统及滚轮测试台架,用于模拟非公路测试。
We are based in a rural location in East Sussex, England. Our facilities offersecure prototype vehicle storage and we have convenient access to fully compliant 4WD chassis-dyno emissions test facilities. Along with access tonon-emissions 4WD chassis dyno facilities and test tracks for appropriate non-highway testing.

Simulation Experience
&Hardware-in-the-Loop(HiL)
仿真及硬件在环项目经历

V6柴油机仿真全功能HiL集成项目(福特项目)
V6 Diesel Vehicle Simulation with Full HiL Integration (Ford)

用于V6发动机的全功能dSPACE HiL台架开发项目,仿真了主ECU所需的所有信号,系统包含了所有执行器附件(喷油器、制动器、阀门)。该系统还针对3个车辆变型进行了配置,以反映发动机安装平台。
Full dSPACE HiL rig developed for a V6 engine to simulate all signals required for main ECU with all ancillaries present in the system (injectors, actuators, valvesetc.). The system was configured for 3 vehicle variants to reflect the engine installation platforms. 

发动机模型基于每个气缸充分燃烧后的热排放情况,为失火和爆震控制提供详细信息。
The engine model was full combustion based heat release for each cylinder toprovide detail for misfire and knock control.

所有需要的模拟量、数字量和网络信号都进行了仿真,提供的测试平台无需任何修改即有能力运行车辆标定。
All required analogue, digital and network signals were simulated to provide a testplatform capable of running the vehicle calibration without any changes. 

该系统还能够在快速原型阶段用于做调校和ECU代码开发,以及用于完整的自动化测试和报告。
The system allowed for calibration activities and ECU code development for rapid prototyping, along with full test automation and reporting. 
 
V10汽油机发动机HiL台架(克莱斯勒项目)
V10 Gasoline Engine HiL Rig (Chrysler)

基于之前的dSPACE硬件平台项目,调整系统用于仿真完整的V10汽油机动力总成,基于自动化测试需求集成了定制的Python程序
Adapted dSPACE hardware from previous project to simulate full V10 gasoline powertrain, integrated with bespoke Python based test automation. 

主要目标是进行回归测试和在主ECU上进行ISO26262代码开发,并生成诊断标定。
Principle objectives were regression testing & ISO 26262 code development on the main ECU and producing diagnostics calibration. 

系统设计每天连续运行24小时,生成“通过/失败”测试报告。在圣诞节期间项目成功地连续运行了2个星期
The system was designed to run 24 hours a day, producing Pass/Fail test reports, with successful operation of 2 weeks continuous running over Christmas 

EV 汽车HiL台架(大陆电子)
EV Vehicle HiL (Continental)

完整的dSPACE 电动车辆仿真,包含电机、逆变器、DCDC转换器、电池、汽车和防盗装置。
Full dSPACE EV vehicle simulation, including motor, inverter, DCDC converter, battery, vehicle and immobiliser. 

搭建了2个一模一样的台架,其中一个运行在客户现场,这样可将测试进展和测试结果分享给客户查看。
2 identical rigs were built so one could be operated at the customer facility, sotest processes and results could be shared. 

主要目标是提供一个动力总成控制器的快速原型设备,运行自动化测试用例和用户定义的测试场景。这些都需要在一个更可控的环境下来了解任何规格缺陷。
Principle objectives were to provide a facility to rapid prototype the powertrain controller, run automated tests and user specific test scenarios that needed amore controlled environment to understand any specification deficiencies. 

测试进程集成到了一个主ECU代码需求定义工具(DOORS)中,因此作为V循环的一部分每个需求能够被逐个地验证,并输出一个自动化报告和数据佐证来支持验证的结论。
The test process was integrated into the main ECU code requirements definition tool (DOORS) so each requirement could be individually validated as part of the V-cycle, with an automated report and data evidence to support the validation. 

Simulink & dSPACE

针对全系列的dSPACE硬件和软件,无论是从完整的台架还是到微型自动化测试盒,我们均有非常丰富的使用经验。
We have extensive experience with the full range of dSPACE hardware and software, from full rigs down to micro auto-box. All projects are fully documented and specified clearly allowing the rig to be handed over to the customer for continued operation along with training and support. 

关于Matlab Simulink的使用经验,同样可延伸至ECU/TCU控制器的软件功能,数据分析方法,M-文件,嵌入式S-功能集和代码编译,用于多个实时目标。
Our Matlab Simulink experience also extends to SW functions for ECU/TCU controllers, data analysis methods, m-files, embedded S-functions and compiling code for numerous real-time targets.
