Multiple-force, dynamically-adjusted, 3-D touch surface with feedback for human machine interface (HMI)

摘要

A control interface system for a vehicle includes an input module, a feedback module, and a system controller. The input module has a touchscreen and a control icon arranged thereon. The feedback module includes a pressure sensor in communication with the input module. The pressure sensor provides a sensor signal to the input module indicative of an applied force on the touchscreen. The system controller is in communication with the pressure sensor through the input module. The system controller provides at least one of a haptic feedback, an audible feedback, and a visual feedback, where the feedback is indicative of one of a selection mode, a slow change mode, and a fast change mode.

1. A control interface system for a vehicle comprising:
a touchscreen and a selectable control icon arranged thereon, the touchscreen is a vehicle touchscreen and the control icon is configured for setting a target cabin temperature; a pressure sensor configured to generate a sensor signal indicative of an applied force on the touchscreen; and a system controller in communication with the pressure sensor to receive the sensor signal, wherein the system controller provides at least one of a haptic feedback, an audible feedback, and a visual feedback, wherein the feedback is indicative of one of a search mode, a selection mode, a slow change mode in which controlled features change slow, and a fast change mode in which controlled features change fast; wherein:
the system controller provides feedback indicative of the search mode when the applied force is within a first predetermined force level range that is a tracking range, and the system controller displays on the touchscreen an image opposite to the applied force and moves the image about the touch screen to track movement of the applied force about the touch screen;the system controller enters a target cabin temperature change mode when the applied force is within an active area of the display screen and within the first predetermined force level range, the target cabin temperature is not changed unless the applied force is greater than the first predetermined force level range;the system controller provides the feedback indicative of the slow change mode when the applied force is greater than the first predetermined force level range and less than a second predetermined force level range, and changes the target cabin temperature at a first rate of speed;the system controller provides the feedback indicative of the fast change mode when the applied force is greater than the second predetermined force level range and within a third predetermined force level range, and changes the target cabin temperature at a second rate of speed that is greater than the first rate of speed; andthe first predetermined force level range is less than the second predetermined force level range and the second predetermined force level range is less than the third predetermined force level range.
