ABSTRACT Building battery packs for various, significantly different applications, is often complex and risky. Detailed cell and pack modeling and simulation tools, along with existing and predicted power and energy profiles significantly reduce the risk of designing and integrating a new pack for new applications on the battlefield. This paper will discuss a number of modeling and simulation techniques, using case studies as examples, that ensure a battery pack, when integrated to the application, will meet the predicted performance goals and specifications. Actual data will also be shown to validate these techniques that significantly reduce development time and risk when providing power to the Warfighter

As a key technology of intelligent transportation system, vehicle type recognition plays an important role in ensuring traffic safety,optimizing traffic management and improving traffic efficiency, which provides strong support for the development of modern society and the intelligent construction of traffic system. Aiming at the problems of large number of parameters, low detection efficiency and poor real-time performance in existing vehicle type recognition algorithms, this paper proposes an improved vehicle type recognition algorithm based on YOLOv5. Firstly, the lightweight network model MobileNet-V3 is used to replace the backbone feature extraction network CSPDarknet53 of the YOLOv5 model. The parameter quantity and computational complexity of the model are greatly reduced by replacing the standard convolution with the depthwise separable convolution, and enabled the model to maintain higher accuracy while having faster reasoning speed. Secondly, the attention mechanism in

As a key tool to maintain urban cleanliness and improve the road environment, road cleaning vehicles play an important role in improving the quality of life of residents. However, the traditional road cleaning vehicle requires the driver to monitor the situation of road garbage at all times and manually operate the cleaning process, resulting in an increase in the driver 's work intensity. To solve this problem, this paper proposes a road garbage recognition algorithm based on improved YOLOv5, which aims to reduce labor consumption and improve the efficiency of road cleaning. Firstly, the lightweight network MobileNet-V3 is used to replace the backbone feature extraction network of the YOLOv5 model. The number of parameters and computational complexity of the model are greatly reduced by replacing the standard convolution with the deep separable convolution, which enabled the model to have faster reasoning speed while maintaining higher accuracy.

VIN - WMI Technical Committee
This SAE Recommended Practice establishes procedure for the issuance and assignment of a World Manufacturer Identifier (WMI) on a uniform basis to vehicle manufacturers who may desire to incorporate it in their Vehicle Identification Numbers (VIN). This recommended practice is intended to be used in conjunction with the recommendations for VIN systems described in SAE J853, J187, J272, and other SAE reports for VIN systems. These procedures were developed to assist in identifying the vehicle as to its point of origin. It was felt that review and coordination of the WMI by a single organization would avoid duplication of manufacturer identifiers and assist in the identification of vehicles by agencies such as those concerned with motor vehicle titling and registration, law enforcement, and theft recovery

Global auto supplier Schaeffler Group has a message for the EV motor market: the company is capable of building custom solutions for many different EV drivelines and use cases. And it is forthright in saying that not all mobility applications need cutting-edge technology to be effective. While some e-motor manufacturers have gone to market with a limited number of models - usually employing similar architecture but different levels of output - from which customers can select, Schaeffler insists it will consider building any motor spec brought to it. Daniel Sayre, e-motor business unit director, said the company is dedicated to adapting and working with customers to develop the best solutions for their vehicles

Maintaining and diagnosing vehicle systems often involves a technician connecting a service computer to the vehicle diagnostic port through a vehicle diagnostics adapter (VDA). This creates a connection from the service software to the vehicle network through a protocol adapter. Often, the protocols for the personal computer (PC) hosted diagnostic programs use USB, and the diagnostic port provides access to the controller area network (CAN). However, the PC can also communicate to the VDA via WiFi or Bluetooth. There may be scenarios where these wireless interfaces are not appropriate, such as maintaining military vehicles. As such, a method to defeature the wireless capabilities of a typical vehicle diagnostic adapter is demonstrated without access to the source code or modifying the hardware. The process of understanding the vehicle diagnostic adapter system, its hardware components, the firmware for the main processor and subsystems, and the update mechanism is explored. Once the

AGE-2 Air Cargo
This SAE Recommended Practice incorporates dynamometer test procedures that produce riding range estimates for electric motorcycles during stop-and-go urban riding on surface streets and commuting trips in urban areas that include operation on freeways. This is typically done using a “coastdown” approach by disengaging the engine and assuming all losses are aerodynamic. However, with inherent losses in an electric motor, and no way to fully disengage the motor, another approach is to use a “on-road, constant speed” (Appendix B) method for fully electric vehicles to develop dynamometer coefficients
