Hands On Detection (Hod) Module

The HOD module activates a hands on sensor to determine if the driver has their hands on the steering wheel. The HOD module receives the sensor input then uses its own internal algorithm to determine if the hands are off or on the steering wheel. The HOD module transmits this determination in a signal to the CADM. The CADM uses this signal and/or the EPS torque sensing signal in order to determine the final hands on / hands off state. When the hands are not detecting on the steering wheel, a message is sent to the IPC to display a warning and the DAL is illuminated.
