Steering system is the main component of the vehicle to turn. For old model cars, they used the gearbox type. As time passes by, steering evolved to power steering run by a belt, a power steering pump, and a rack and pinion assembly. Today, with the help of technology they invented the Electronic Power Steering (EPS). Electric motor and electric control unit are integrated into the steering column assembly making for a simple and compact system. Unlike conventional hydraulic power steering system, EPS doesn't require pipes, pulley, hydraulic pump and power steering fluid to improve fuel efficiency. The EPS system activates the power steering motor only when the driver turns the steering wheel. It means that the electricity is only used when power assist is required so that the energy requirement is reduced when the vehicle is going straight which helps to reduce overall fuel consumption. The fact that the system does not require power steering fluid provides a further environmental bonus. The design project aimed to design, construct, and develop an electronic power steering interactive instructional trainer that will serve as reference for other clients who have the same type and model of steering installed in their vehicle. The steering system was restored to its normal working condition, especially by repairing, renovating and rebuilding the whole system. After spraying the primer to all metals and let it dry, it was again sanded and sprayed with the base color. The metals are coated several times before spraying the clear coat. The frame has a dimension of 60" x

36" x 25". Angular bars that has the size of 2" x 2" x 20' and some flat bars are used in the design project. Four caster wheels were placed on the two rear corners and two front corners of the frame for ease and strength of arranging and placing the instructional trainer. Rims, tires, lower control arms, carseat, caster wheels, and plywood are installed to make the frame complete for users comfortability. The sockets and wires are then tapped to the Vios for the prototype to be able to have a ease of connecting the pre — attached wires for the electronic power steering to function accordingly. Sockets are composed of two, two - pin sockets. One is for the main supply (socket A) which will give the control module the voltage that it needs and one for the malfunction indicator light (socket B). And one eight — pins socket which is pre attached to the wires that are connected to the main wires that is needed to be connected to the control module.
The design project was found reliable, presentable, and very useful to the students to gain more knowledge and improve the skills in using the trainer. The participants gave an overall rating of 4.7 with a corresponding degree of outstanding. Based on the results, the authors recommend the following improvements to be done for better functionality of the trainer use stronger frame materials for more rigidness, replace suspension system with MacPherson strut suspension system redesign the layout of the components, make it more compact.
