Abstract: A device and a method for locking and/or unlocking a motor vehicle opening panel and vehicle having the device. The device includes a detection wall having an inner side and an opposite outer side, the outer side forming a contact detection region, and a detection component arranged against the inner side for detecting contact between a user's finger or hand and the outer side. The detection component includes a sensor having a layer of a piezoelectric material which has surface undulations in the form of ridges. The layer of piezoelectric material is configured to detect predetermined contact on the outer side with a view to controlling the locking or unlocking of the opening panel.

Abstract: A passenger compartment equipment for controlling a function of a motor vehicle includes a body that includes a control region having sensors which are configured to generate an electrical signal in response to an action such as a force or pressure exerted on at least one of the sensors and which can be connected to an electronic control unit (ECU) of the vehicle. The equipment further includes a haptic feedback module that can be connected to the ECU adjacent to the control region and to the caps covering the sensors and the haptic feedback module. The electrical signal generated by the sensors is transmitted to the ECU for analysis and for conversion into a command of a function of the vehicle and of the haptic feedback module.
