A door system is provided and includes=a door assembly operable to assume an open position at which an aperture is opened and a closed position at which the aperture is closed, a sensor assembly and a controller. The controller is coupled to the door assembly and configured to instruct the door assembly to normally assume the closed position and to assume the open position in accordance with an open signal being issued by the sensor assembly. The sensor assembly is configured to track the individual, determine whether the individual is likely to be approaching the aperture from the tracking and issue the open signal in accordance with a determination that the individual is likely to be approaching the aperture.

A method for detecting objects in the surroundings of a vehicle for a door opening system or a collision warning system for vehicle doors using at least one surroundings sensor is disclosed. The vehicle includes at least one movable component. The method includes detecting objects in the surroundings of the vehicle using the at least one surroundings sensor, detecting a current position of the at least one movable component, and identifying false objects from the detected objects based on their positions between the at least one movable component in its current position and in its normal position.

A device for detecting contact with and/or an approach toward a motor vehicle. The device includes a vibration generator, including a first electromechanical transducer configured to be mounted on an external element of the motor vehicle, and an electrical signal generator that delivers, to the first electromechanical transducer, an electrical signal oscillating at an excitation frequency; a rechargeable energy storage device, for supplying power to the electrical signal generator; and a vibration sensor, consisting of a second electromechanical transducer configured to be mounted on the external element of the motor vehicle. An output of the vibration sensor is connected to the rechargeable energy storage device, such that at least part of the electrical response signal recharges the rechargeable energy storage device.

An opening and closing body control device for a vehicle includes: a control unit configured to control an opening and closing body drive device driving an opening and closing body of a vehicle to open and close the opening and closing body based on an operation request; and a detection unit configured to detect an obstacle present around the opening and closing body based on a detection result of an obstacle sensor. The control unit sets an operation speed of the opening and closing body to a first speed when the obstacle is not detected during an operation of the opening and closing body, and sets the operation speed to a second speed or less and causes the opening and closing body to stop at a position where the opening and closing body is close to the obstacle, when the obstacle is detected during the operation.

A computer-implemented method comprises: collecting, in a vehicle having an advanced driver assistance system (ADAS), sensor data using an ADAS sensor suite of the vehicle, the sensor data collected while the vehicle is moving and reflecting surroundings of the vehicle; generating a three-dimensional (3D) map of the surroundings using the sensor data; defining a boundary condition regarding the vehicle based on the 3D map; and controlling a closure actuator of a closure of the vehicle based on the boundary condition, the closure actuator configured for opening or closing the closure, the closure actuator controlled without the closure having any obstacle detection sensor.

An obstacle detection device includes: an ultrasonic sensor signal processing unit detecting at least a distance to an obstacle among the distance and a shape of the obstacle based on an output of an ultrasonic sensor, the ultrasonic sensor being disposed on a door of a vehicle and detecting the distance within a predetermined detection range by an ultrasonic wave; a camera image processing unit detecting the distance and the shape based on an output of a camera of the vehicle, the camera capturing an image of an area including a trajectory range when the door is opened and a detection range of the ultrasonic sensor; and a controller performing open operation control of the door based on detection results of the ultrasonic sensor signal processing unit and the camera image processing unit.

A method for identifying and classifying objects in the surroundings of a motor vehicle, which method uses merely a single sensor for object detection. The method is characterized in that this single sensor moves in space while the object is being detected. In this case, during the measurement, the single sensor would act to a certain extent like a second sensor. The echo signals, reflected by the object, of different measurement cycles can be used to determine the differential speed, distance and angle. The method provides the possibility of being able to classify, by means of a single sensor, objects and items in the surroundings of a motor vehicle in terms of their size.

A vehicle having a tailgate configured to move between retracted and extended positions is disclosed. The vehicle includes a first detection unit, a second detection unit, a third detection unit and a control unit. The control unit obtains a first input from the first detection unit and determines whether the tailgate is in extended position. The control unit further obtains a second input and a third input from the second and third detection units respectively, when the tailgate is in the extended position. Responsive to obtaining the second and third inputs, the control unit identifies a tailgate extended orientation. In addition, the control unit detects an obstacle presence in a vehicle rear side proximity and calculates a calibrated distance between the obstacle and a tailgate top side, based on the tailgate extended orientation. The control unit notifies a vehicle user when the calibrated distance is less than a threshold.
