More Information
Summary:A presence detection device including a sensor connected to a microcontroller, the sensor including a first detection capacitor arranged in a first detection area, and a second detection capacitor arranged in a second detection area. The microcontroller is configured to recurrently repeat a phase of measuring a measurement signal by charging/discharging the first detection capacitor from/into the second detection capacitor, and to detect a presence of a user in the first detection area and/or the second detection area according to the measurement signal. Also disclosed are a motor vehicle including a detection device and a detection method.
