Regarding conformal coatings to improve the moisture resistance of electronic components, there is no established method for evaluating moisture resistance after coating on a substrate, making it difficult to compare the performance of each material. In addition, it is necessary to test while applying voltage for a long period of time, which is a heavy burden. In this paper, we propose a unique drip test method to resolve these issues.

The effectiveness of a preventive measure for moisture-proofing automotive electronic components through the use of conformal coating at the PCB surface is demonstrated. However, it is unclear which parameters are crucial for ensuring moisture-proofing efficiency. In this study, we present the results of a water drop test that highlights the differences between various materials used for conformal coating.

Evaluation of Autonomous Development using a Flat Type Dynamometer that can be Installed in the Tyre House of a Vehicle -First Report-

Yoshihisa Hojo･Yuichi Takasaki･Kohei Yasumoto･Kenji Terada･Rentaro Kondo (Toyo Denki Seizo)

We have developed a flattened dynamometer that can be installed in the tyre house of a vehicle.　
This dynamometer is steerable and can also house the vehicle's mechanical brake, which is 94 kW, 1000-2000 min-1 per wheel, with a maximum short-time torque of 1350 Nm.
This paper refers to the possibility of evaluating the development of autonomous, such as emergency braking and emergency avoidance, by placing this dynamometer on all four wheels.

Consistency Verification of Signal Processing for Millimeter-wave Radar using Physical Sensor Model and DIVP Simulation Platform (2nd Report)

In order to perform reproducible simulation evaluations in various traffic environments, the simulation platform and the sensor model should accurately simulate physical phenomena. In the case of millimeter-wave radar, bumpers affect the propagation of electromagnetic waves, which varies with the material and shape of the bumper on each vehicle. This report shows the results of the implementation and verification of the impact of bumpers on the propagation of electromagnetic waves in the DIVP simulation environment.

SIL-HIL Hybrid Simulation Environment for Automotive Software Validation (Second Report)

As Software Defined Vehicles (SDV) become more common and ECU software becomes more complex, Software In the Loop (SIL) and Hardware In the Loop (HIL) validation environments are getting more important. In this study, we have investigated simulation performance in an environment close to the actual ECU functionality by creating a prototype hybrid simulation environment of SIL and HIL. The SIL-HIL Transition is also discussed.
