  • Patent number: 10246009
    Abstract: A user-activated, non-contact power closure member system and method of operating a closure member of a vehicle are provided. The system includes at least one sensor for sensing an object or motion. An indicator is located on the vehicle to inform the user of the appropriate location to make an activation gesture, which initiates opening of the closure member. The indicator is located adjacent the at least one sensor. The indicator also informs the user if the system is activated, in motion, and/or waiting for the activation gesture. An electronic control unit is connected to the at least one sensor and the indicator. When the object or motion is detected by the at least one sensor, the control unit notifies the user with the indicator, determines if the object or motion is the correct activation gesture, and initiates movement of the closure member.

The contact sensor has an output that depends on a contact or non-contact state between the steering wheel and an occupant in the vehicle. The apparatus further includes a contact determination ECU that detects the contact state when the output of the contact sensor is greater than or equal to a predetermined threshold, and detects the non-contact state when the output is less than the predetermined threshold. In addition, the apparatus includes a temperature detection module that detects the ambient temperature of the steering wheel. The contact determination ECU includes a threshold changing section that changes the threshold based on a detection result of the temperature detection module.

  • Patent number: 10198108
    Abstract: Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.
