A system and method for determining whether a vehicle driver is holding a steering wheel of the vehicle while the vehicle is in an autonomous driving mode. The vehicle will include an electric power steering (EPS) system and may include an active front steering (AFS) system, both of which include a motor that can apply a high frequency and low amplitude perturbation signal to the steering wheel of the vehicle that is not felt by the vehicle driver and does not cause the vehicle to turn, but is able to be detected by a steering angle sensor. The method subtracts a steering angle command signal from the steering angle signal and removes road disturbances, and then determines whether the induced perturbation signal is present in the steering angle sensor signal. If the perturbation signal is present, then the system knows that the vehicle driver is not holding the steering wheel.

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).

A brake-by-wire vehicle braking system is augmented with “squeeze” sensors placed in the steering wheel of the vehicle enabling a vehicle operator to stop the vehicle more quickly in an emergency situation by eliminating the significant times that it takes to move a driver's foot from the accelerator to the brake pedal and then depress the brake pedal. An important objective is to achieve a faster vehicle stop by allowing the driver to optionally eliminate foot movement from the accelerator pedal to the brake pedal and also the depression of the brake pedal. This invention also potentially allows a driver to squeeze a steering wheel to slow a vehicle, perhaps to comply with a lower speed limit, or accomplish the fastest possible “hard-stop” in an emergency situation.
