Abstract
A system and method are provided herein for dynamic haptic feedback in vehicles. Speakers are integrated into vehicle seats to provide tactile feedback in synchronization with internal sound and external sound synthesis perceptible to an occupant to enhance awareness of vehicle dynamics.
Claims20
A haptic feedback system for a vehicle, comprising:
- one or more speakers integrated into a vehicle seat;
- a vehicle interface with internal and external sound synthesis modules configured to generate audio signals based on vehicle dynamics;
- and
- a control unit including instructions stored on non-volatile memory, the instructions being executable to process audio signals and vehicle dynamics data, directing low-frequency components to the seat-integrated speakers to generate tactile feedback perceptible to an occupant, wherein the tactile feedback supplements auditory feedback to enhance perception of vehicle dynamics.
1 more element
A method for generating dynamic haptic feedback via integrated seat speakers in a vehicle seat, comprising:
- receiving vehicle dynamics data from sensors of the vehicle;
- synthesizing haptic signals based on the vehicle dynamics data and synchronized with audio synthesis signals from internal and external sound synthesis modules;
- extracting low-frequency components from the haptic signals and the audio synthesis signals;
- outputting haptic feedback corresponding to the low-frequency components via the integrated seat speakers.
1 more element
A vehicle, comprising:
- a plurality of sensors configured to detect vehicle dynamics including one or more of:
- throttle position, motor load, vehicle speed, acceleration, braking force, road conditions, and ADAS alerts;
- a driver seat including integrated seat speakers;
- a controller including instructions stored in non-transitory memory thereof and executable to:
- synthesize haptic signals based on the vehicle dynamics indicated by sensor input from the sensors;
- output the haptic signals via the integrated seat speakers.
