With EPS, the driver needs only 2Nm to rotate the steering wheel in any condition. Electric power steering system consists of torque sensor, DC motor assist, current sensor, and an Electronic Control Unit (ECU). A classic proportional control method is implemented in the ECU to control the assist torque done by the DC motor assist. The proportional controller with a Kp gain of 0.6 results in a rise time of 0.1 second. Instead of direct torque sensor, an incremental encoder which is used to detect the change of steering wheel position is then converted into steering torque. Two models of EPS systems are tested, system which includes a current sensor and system which do not use a current sensor. System with a current sensor gave poorer result than the other system because of the low sensitivity and the unpredictable delay of the current sensor. The impact of using incremental encoder is that the driver has to give quite large steering torque to rotate the steering wheel in the beginning before the DC assist motor starts working.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Current sensors,Electric power steering,Electric power steering system,Electronic control units,Incremental encoder,Proportional control,Proportional controller,Prototype development[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Electric Power Steering System,Electric vehicle,Electronic Control Unit[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICEVTIMECE.2015.7496683[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
