A non-contact obstacle detection (NCOD) system for a motor vehicle and a method of operating the non-contact obstacle detection system are disclosed. The NCOD system includes a main electronic control unit adapted to connect to a power source. At least one non-contact obstacle sensor is coupled to the main electronic control unit for detecting obstacles near a closure member of the vehicle. The control unit is configured to detect an obstacle and cease movement of the closure member in response to the obstacle being detected. Additionally, the control unit is configured to release a latch and apply power to a motor in response to the obstacle not being detected. The control unit is also configured to determine whether the closure member is in a full open position, and continue to apply power to a motor coupled to the closure member if the closure member is not in the full open position.

A radar sensor for a vehicle includes a control unit and an antenna array. The radar sensor is configured to perform a three-dimensional scan to determine a vertical and a horizontal position of an object in order to assist with distinguishing the geometrical nature of the object.

A collision avoidance device for avoiding collision with an object in a door zone of a vehicle, including a sensing module, a damping module and a control unit. Upon detecting an object moving toward a door of the vehicle, the sensing module calculates a velocity of the object. The control unit controls the damping module to apply a resistance force to a pivot unit that pivots the door for enabling the door to rotate at most at an initial rotational speed without detection of an object, a first rotational speed slower than the initial rotational speed when the velocity is smaller than a predetermined value, or a second rotational speed slower than the first rotational speed when the velocity is greater than the predetermined value.

A touch pad for operating an e-latch assembly of a motor vehicle entry system that includes a control circuit with a backup energy source and method of operating the entry system are provided. The touch pad includes a touch pad controller in communication with the control circuit of the e-latch assembly. The touch pad also includes at least one entry input sensor coupled to the touch pad controller for outputting a signal indicative of a touch to operate the e-latch assembly. The touch pad further includes a mechanical emergency switch assembly adjacent the at least one entry input sensor and including a plurality of pins electrically coupled to the control circuit for operating the e-latch assembly when the at least one input sensor is not operable due to one of a power loss and malfunction of the at least one input sensor.

A door control device includes: a sensor device that acquires target information; a door operation unit operated by an occupant; an actuator that changes a door from a closed state to an open state; and a control unit that drives the actuator to change the door from the closed state to the open state. When it is determined that an obstruction is not detected at an operation detection point of time when operation of the door operation unit is detected while the vehicle is stationary, and when it is determined that the obstruction is detected during a period from an operation start point of time of the door operation unit to a point of time when operation continuation time reaches a first time, the control unit keeps the door in the closed state regardless of the operation continuation time.

Disclosed is a method (50) of providing finger pinch protection at a hinge area of a swing door-based entrance system (1) having a motorized automatic door operator (30) for opening (2) of the swing door (10) in an automatic mode of the entrance system (1), wherein the entrance system (1) also has a manual mode in which a human user may cause opening and closing of the swing door (10) by manual force. The method involves monitoring (52), by a first sensor function (S1), for presence of a person or object in a first zone (PD) at the first door leaf surface (12-1) and non-proximate to a vertical door edge (14). The method also involves monitoring, by a second sensor function (S2), for presence of a person or object in a second zone (PDHA) at the first door leaf surface (12-1) and proximate to said vertical door edge (14). When any of the first sensor function (S1) or second sensor function (S2) detects presence in the first zone (PD) or second zone (PDHA) in the automatic mode during an ongoing opening of the swing door (10), the automatic door operator (30) is controlled so as to stop opening of the swing door (10). When the second sensor function (S2) detects presence in the second zone (PDHA) in the manual mode, the automatic door operator (30) is controlled so as to counteract an attempt by a human user to manually open the swing door (10). A corresponding entrance system (1) is also disclosed.

A door opening and closing apparatus includes a setting unit configured to set at least a part of one of a first detection range and a second detection range as a start zone in which a first phase of a setting movement made by a detection target is to be detected, and to set a part of another one of the first detection range and the second detection range as a trigger zone in which a second phase of the setting movement is to be detected, based on first distances measured by a measurement unit. Upon determining that the detection target has made the setting movement including a movement between the start zone and the trigger, based on changes in the distances measured by the measurement unit, the control unit causes a driving unit to open or to close the door.

A vehicle having a powered tailgate is provided. The vehicle includes a body, a powered tailgate pivotally connected to the body, an actuator operatively coupled to the tailgate to move the tailgate between open and closed positions, and sensors configured to sense an object in a swing path of the tailgate. The vehicle also includes a controller for processing signals output from the sensor and identifying and classifying the object, and controlling the actuator to move the tailgate between the open and closed positions based on the classified object.

A safety system for an automatic door including an ultrasonic sensor installed in a rotary frame to detect motion of the rotary frame in order to stop operation of an automatic door in order to prevent injury from the door.

A method of operating an entry system of a motor vehicle includes monitoring a battery voltage and the entry system continuously using a control circuit of the latch assembly in a non-emergency mode. Power is provided to the control circuit in the event of a loss of power from a main power source using a backup energy source of the control circuit. The method includes transitioning to an emergency mode in response to determining loss of power from the main power source or failure of the component of the entry system. An actuation group associated with the latch assembly is operated with the control circuit using power from the backup energy source of the control circuit in response to determining that actuation from a plurality of pins of a mechanical emergency switch assembly indicates a command from a user to unlatch the closure member in the emergency mode.
