A system and method for determining whether a vehicle driver is holding a steering wheel of the vehicle. The vehicle will include an electric power steering (EPS) system and may include an active front steering (AFS) system. The vehicle may further include autonomous or semi-autonomous driving features or safety features, such as Lane Centering Control (LCC) or Lane Keeping Assist (LKA). The system monitors steering torque and steering angle signals, determines a resonant frequency of oscillation of the steering system from the measured data, and compares the resonant frequency to a known natural frequency of the steering system. If the resonant frequency is lower than the known natural frequency, then the system knows that the vehicle driver is holding the steering wheel. A measured steering torque greater than a threshold value is also taken as an immediate indication of the driver holding the steering wheel.

An apparatus and method to automatically and individually, simultaneously, and/or sequentially operate a horn system a light system and/or a braking system of a vehicle. A threat detection system secured in the vehicle detects threats and sends one or more signals, directly or indirectly, to the braking, horn and/or light systems to activate those systems to improve delivery time of safety and/or emergency warning signals to third party vehicles and pedestrians. The systems can be connected directly via relay, or may incorporate an intermediary electronic control unit or controller to coordinate operation of the systems. A deactivation device enables a driver to disconnect the threat detection system from the horn, light and braking systems to permit manual control of those systems. A second deactivation device permits the driver to disconnect coordinated control of the brake, horn and/or light systems from the threat detection system. The apparatus permits automated post-crash operation of the horn and/or light systems to provide audible and visual warning signals to third party vehicles and pedestrians and includes an optional backup battery to operate the horn and light systems should the main battery post-crash. A GPS-controlled turn-signal system permits automated activation of vehicle directional arrow lights.
