Car Brake Works as Indicator Tool

Accidents caused by malfunctioning of the brake light system are increasing in line with the rise in road facilities. It provides space for drivers to drive vehicles quickly. To overcome this problem, a system that can signal the driver must rapidly identify the damaged brake lights. The purpose of this study was to produce a car brake indicator tool. This tool is an electronic device that functions to determine the brake light when one of the brake lights is off by automatically giving a signal on the car's dashboard. The method used to produce brake work indicator tools consists of designing, manufacturing, and testing. The testing process has been carried out through a lux meter, and the test variables include testing the use of electric current, voltage when the tool is working, and trying the performance of the device on the car. From testing this tool, the results obtained when the current usage of the tool is working, namely before the induction works of 2 amperes and when the induction works it is 0.5 amperes. The magnitude of the voltage when the device is used is 11.8 volts. Based on the experiments that have been carried out, there are no disturbances in the lighting system or other systems on the car when this tool is working. This tool can work well to provide convenience and comfort when driving by car.

Motorcycle Conspicuity Issues and Intervention: A Systematic Review

Background: Conspicuity has been one of the key factors in motorcycle road crashes around the world. The inability and difficulty of other road users in detecting motorcycles either at day or at night have contributed to conspicuity related motorcycle crashes. This literature review attempts to understand the motorcycle conspicuity issues in road traffic. The review also analyses relevant types of conspicuity intervention in terms of its effectiveness in enhancing motorcycle conspicuity that had been discussed in past studies. Methods: Using specific keywords and search terms, relevant articles were screened, identified and analyzed systematically using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: Twenty-seven final articles were reviewed and found that almost every part of motorcycle and motorcyclist’s conspicuity intervention have been covered in past studies. In terms of conspicuity aids, the majority of past studies discussed conspicuity enhancement in the frontal area, particularly on motorcycle daytime running headlight (DRH) color and configurations. Few other studies have discussed in other areas, particularly on rear running and brake light and motorcycle color. There were also numerous studies looking at motorcyclists’ appearances in terms of their attire and helmet color. Conclusion: Motorcycle and motorcyclist’s appearances are highly associated with the risk of motorcycle crashes. The most important part of enhancing motorcycle conspicuity is to ensure motorcycle appearance is always in contrast with the road traffic environment.

Change of driver’s response time depending on light source and brake light technology used

This paper deals with finding out the influence of the type of light source of car brake lights on the reaction time of the driver of the preceding vehicle. The driver’s reaction time was measured in the form of pressing the brake pedal depending on the lighting of brake lights on the leading vehicle. The measurement evaluation consists of a comparison of the phase shift between the brake light signal of the first vehicle and the brake light signal of the second vehicle. The experimental measurement was performed for five people using the classic light bulb, afterwards, an LED light source for the brake lights of the first vehicle. The records confirmed that the driver’s reaction time depends on many factors, with the source and intensity of the brake lights also playing an important role. Further, it affects the reaction time and the activity or inactivity of the rear sidelights. The reaction time of the driver of the preceding vehicle was extended with their activation.

ANALISIS KETINGGIAN TOOL PUNCH RIVET TERHADAP HASIL RIVET ING CONTACT PADA SWITCH LAMPU REM MOTOR TIPE C8EA

The product of CBEA Terminal B / B2 Assy is one of the C8EA type Switch components used for brake light switches on two-wheeled vehicles. In the manufacturing process often experience Contact Crack. Contact Crack problems occur in the rivet ing process. This study aims to reduce / eliminate the contact Crack problem, the method used is to conduct research on variations in the height of the punch in the rivet ing process. The initial height of the punch before the research is 49.10 mm, in this study the height of the punch to be examined is 48.60 mm, 48.70 mm, 48.80 mm, 48.90 mm and 49.00 mm. The results obtained for the most appropriate punch height are the height of 48.60 mm with the contact Crack ratio of 3/20, the size of the Crack & contact size entered into the standard, the flexural strength is still standard and the average hardness produced is 92.52 HV which is included in the maximum standard.

Arduino-based Automatic Control System for Turn Signal and Brake Lights on Motorcycle

The number of motorcycles circulating on Indonesian roads in 2018 reached 111,470,878 units. With this amount of traffic on the highway becomes congested and potentially high accidents. One of the factors causing the accident is the motorcycle rider's negligence in using turn signal and brake lights. This study aims to make a tool that works automatically to control the active and inactive brake lights and turn signal on a motorcycle. This tool was successfully developed and implemented using an arduino microcontroller and controller information was taken from the Throttle Position Sensor, Speed sensor, turn signal and brake light control switches. Jumlah sepeda motor yang beredar di jalan raya Indonesia pada 2018 mencapai 111.470.878 unit. Dengan jumlah ini lalu lintas di jalan raya menjadi padat dan rawan akan kecelakaan. Salah satu faktor penyebab kecelakaan adalah kelalaian pengendara sepeda motor dalam menggunakan lampu sein dan lampu rem. Penelitian ini bertujuan untuk membuat sebuah alat yang bekerja secara otomatis untuk mengatur hidup dan matinya lampu rem dan lampu sein pada sepeda motor. Alat ini berhasil dikembangkan dan diimplementasikan dengan menggunakan mikrokontroler arduino dan informasi dari sensor seperti Throttle Position Sensor, Speed sensor, saklar lampu sein dan rem.
