US Patent:

20110246028, Oct 6, 2011

Filed:

Apr 1, 2011

Appl. No.:

13/078793

Inventors:

Jason LISSEMAN - Shelby Township MI, US
David ANDREWS - Ortonville MI, US
Jerome BOSCH - Romeo MI, US

International Classification:

B62D 1/06
B60R 16/02

US Classification:

701 45

Abstract:

The invention relates to a vehicle safety system includes a steering wheel, a plurality of pressure sensitive sensors located in the steering wheel, and a control unit. The pressure sensitive sensors can be located in different regions of the steering wheel. The pressure sensitive sensors can determine if a driver's hand is pressing upon a respective region of the steering wheel associated with one or more of the plurality of pressure sensitive sensors. The control unit can be configured or programmed to determine if at least one of the driver's hands is pressing upon a region of the steering wheel for a predetermined amount of time.

B60R 21/2165

Abstract:

Various implementations of a horn system include one or more force sensors disposed on a first portion of a driver air bag module and one or more actuators disposed on a second portion of the driver air bag module. For example, the force sensors may be disposed adjacent a perimeter of a base plate of the driver air bag module, and the actuators may extend inwardly toward the force sensors from an inner surface of a cover of the driver air bag module, or vice versa. To actuate the horn, the cover is moved axially toward the base plate, causing the actuators to apply force to the force sensors. Force signals received from the force sensors are used by one or more processors to determine characteristics of the force received and/or select a control message for communicating to the horn system based on the force signal characteristics.

G06F 3/01

Abstract:

Implementations include methods of controlling a haptic response comprising receiving a force signal from a force sensor; determining a force magnitude associated with the force signal; comparing the force magnitude with an initial threshold force amount to determine whether the force magnitude exceeds the initial threshold force amount; measuring an elapsed time that the force magnitude exceeds the initial threshold force amount; comparing the elapsed time to a minimum elapsed time; if the elapsed time being greater than the minimum elapsed time, generating a haptic feedback control signal, the haptic feedback control signal causing a haptic actuator to propagate a plurality of pressure waves at a propagation frequency, the propagation frequency being proportional to the force magnitude; and generating a scroll control signal that causes a menu system to scroll through a plurality of menu options provided by the menu system at a scroll frequency associated with the propagation frequency.
