R&D Center) and Dr. Orhan ATABAY (Istanbul Technical University, Mechanical Engineering Faculty, Automotive Laboratory) In automotive industry, systems become more complex and development period is reduced each day. Innovations need to be tested and applied quickly due to the hard competition. This leads virtual and laboratory testing become more important. Hardware-In-The-Loop (HIL) testing plays crucial role in this area.

2 A user friendly interface controls HIL test systems and test bench adaptations of the interface will be explained. Test Benches seen in OTAM Laboratories O T A M A U T O M O T I V E T E C H N O L O G I E S R & D CE N T E R . Introduction O T A M A U T O M O T I V E T E C H N O L O G I E S R & D CE N T E R . Topics will be OTAM Testing & Control Software Overview Brief information about the software Features Capabilities Test Bench Hardware Adaptation of the Testing Software Test Benches developed by OTAM Steering System Test Bench & OTAM Testing Software Control Software Driver Development for OTAM Testing Software (3-Axis Steering System Test Bench) TCP based Comm. Protocol Development for Control Software 5 Axis Steering System Test Bench OTAM Testing and Control Software Overview Test systems consist of many sub systems with different control and automation algorithms.

3 To control all equipment of a test system, a general purpose testing software is developed. A user friendly interface configurable to control almost any sensor and actuator hardware on the market. In other words, OTAM Testing and Control Software is a multipurpose, user friendly, flexible, customizable universal testing software. O T A M A U T O M O T I V E T E C H N O L O G I E S R & D CE N T E R . OTAM Testing and Control Software Overview O T A M A U T O M O T I V E T E C H N O L O G I E S R & D CE N T E R . OTAM Testing and Control Software Overview Mode selection lets user switch between run & design mode. User operations done via gauges & indicators. Buttons let user align gauges or indicators.

4 User form lets user design an individual control panel. A customized user interface for a hydraulic cylinder and electric motor control. O T A M A U T O M O T I V E T E C H N O L O G I E S R & D CE N T E R . OTAM Testing and Control Software Overview Communication protocols, connection orders, channels, control structures, setting forms are defined in-house implemented driver SW modules. Menu items can be used once drivers are installed. Implementations are done through user channels. Channels are defined in the driver software. Available user channels: Input Output Input Output Analog In. 6. Virtual Analog Out. Digital In. Digital Out. An example of a channel setting: defining a channel name.

5 Channel type selection. Hardware selection. O T A M A U T O M O T I V E T E C H N O L O G I E S R & D C O M P A N Y OTAM Testing & Control Software Overview User can send data thru output type channels and gather data thru input type channels. Analog channels are used for numeric value transfer. Digital channels can receive/return true or false states. Virtual output channels are highly useful to stream out data from a virtual data source. Virtual Input channels are used to collect data from several files consist of any type of information. Calibration form. For sensor type hardware, after channel creation: Calibration specifications should be filled out for proper measurement. To do this, OTAM Testing & Control Software provides a calibration form that is accessed thru settings tab.

6 Unlimited calibration points can be defined. This lets user work with non-linear sensors as well. O T A M A U T O M O T I V E T E C H N O L O G I E S R & D C O M P A N Y OTAM Testing & Control Software Overview As mentioned, software can be switched between run and design mode. Once configuration of the user form is done, run mode is switched to control hardware and store gathered data. The testing and control software stores measured data, channel settings, and other software related information in an SQL database. Any user configuration can be saved and called back. Two different of message types are displayed in the log window which appears as soon as the software is started. The log window lets user watch the status of connection, errors and alerts in detail.
