These warning systems detect the presence of vehicles in blind-spot zones and alert the driver. In this simulation kit, the system consists of a plexiglass structure to simulate the loads and a set of boards to drive the application (AEKD-BLINDSPOTB1). Two cars are placed on the demo: one is stationary, while another car with embedded magnets moves on the conveyor belt driven by a gear-DC motor. A Hall sensor under the belt measures the magnetic field around it and a LED near the stationary car indicates when the blind-spot warning signal is triggered. The application is controlled by: a 32-bit automotive microcontroller (SPC58EC80E5) a VIPower actuator board (EV-VN7050AS) with a high side driver used to drive the conveyor belt geared DC motor a LED driver board (AEK-LED-21DISM1) drives the warning LED Figure 1.
