A capacitance sensor includes a switch control unit that performs a first switching process that turns on a first switch and then repeatedly performs a second switching process that complementarily switches off and on second and third switches that are respectively connected to second and third capacitors; an obtaining unit that calculates, as a sensor output value, a number of times the second switching process is repeated until a magnitude relationship reverses between an intermediate potential and a reference potential; a calculation unit that calculates a sensor output corrected value obtained by correcting the sensor output value such that a resolution becomes uniform; and a determination unit that determines whether a detection target exists from a magnitude relationship between a sensor output difference value and a determination threshold value.

A door opening and closing device includes: a door drive unit capable of opening and closing a door; a detection means for detecting a subject present in an approach area; a measurement unit that measures a distance from the detection means to the subject; a determination unit that determines whether the subject has stopped in the approach area; a setting unit that sets a trigger zone in the approach area a; and a control means for starting control to drive the door drive unit when the subject is determined to have moved into the trigger zone. The setting unit sets the trigger zone to drive the door drive unit on the basis of the separation distance from the detection means to a stopped position.

A door opening/closing device includes a detection unit which detects a foot of a person present near a front door; and a vehicle door opening/closing device main body which opens a rear slide door, when the detection unit detects the foot of the person, wherein when the foot of the person is not detected within a prescribed time after being detected, the detection unit outputs a pseudo outer door handle switch on signal which demands the vehicle door opening/closing device main body to open the rear slide door, and when detection is continuously performed during a prescribed time or longer from when the detection unit has detected a detection target, the detection unit does not output the pseudo outer door handle switch on signal.

Disclosed is a method for opening an opening element of a motor vehicle having a device detecting a predetermined movement of a user's body part, including a Doppler radar, including an antenna, radar waves transmitter/receiver and a radar wave processor. The method includes detection modes and standby modes with reduced wave frequency, the method including during standby: Phase demodulating the reflected radar waves and determining a first signal representing a phase variation of the reflected waves over time; Phase-shift demodulating the reflected radar waves, and determining a second signal representing phase variation of the reflected waves shifted as a function of time; Comparing threshold to maximum value of the absolute values for the first and second signals; Exiting the standby mode and triggering the detection mode if the maximum is greater than the predetermined threshold; Opening the opening element if the predetermined movement is detected during the detection mode.

The invention relates to automotive electronic technologies, and in particular, to an automobile remote control key, a vehicle control method using an automobile remote control key, and a computer-readable storage medium for implementing the method. According to an aspect of the invention, a vehicle remote control key includes: a sensor configured to obtain movement data of the automobile remote control key; a control unit coupled to the sensor and configured to recognize a motion pattern of a user based on the movement data; and a wireless communication module coupled to the control unit and configured to send a message about the motion pattern to a vehicle control system, so that the vehicle control system generates a corresponding control command.

The present invention includes: a vehicle exterior image acquisition unit acquiring a vehicle exterior image being an image of an external surrounding of a vehicle; a vehicle interior image acquisition unit acquiring a vehicle interior image being an image of an interior of the vehicle; a person recognition unit respectively recognizing, based on the vehicle exterior and interior images, motions of a person outside the vehicle and a person in the vehicle; and a door control unit controlling a state of a door of the vehicle, wherein, if a person outside the vehicle approaching the vehicle has been recognized based on a recognition result of the person recognition unit, the door control unit executes an opening operation on the door if it has been determined that the person in the vehicle has performed a specific motion determined in advance regarding the approaching person outside the vehicle.

A vehicle includes a body supporting at least one camera. The at least one camera is positioned to collect images of objects outside of the vehicle. The vehicle also includes a selectively operable vehicle system and a controller operatively connected to the at least one camera and the selectively operable vehicle system. The controller includes a gesture recognition system operable to process a gesture made by a person associated with the vehicle collected by the at least one camera and activate the selectively operable vehicle system associated with the gesture.

Methods and systems are provided for an automated door system for a vehicle. In one example, the automated door system may include a key fob configured with a transmitter. A set of sensors may be located at a door of the vehicle which may be communicatively linked to a vehicle control unit. A position of the key fob relative to the door may be monitored by the set of sensors to provide hands-free actuation of the door motor.

Methods and systems are provided for an automated door system for a vehicle. In one example, the method for a vehicle may include operating an automated door system to enable hands-free actuation of a set of door vehicles while the height of the vehicle is not changing and when the vehicle height is changing, suspending operation of the automated door system until the floor has stopped changing height.

An opening and closing body control device is applied to a vehicle that includes a vehicle body having an opening, an opening and closing body configured to open and close the opening, a drive unit configured to operate the opening and closing body, and a detection device configured to detect a gesture operation of a user. The opening and closing body control device includes: a position acquisition unit configured to acquire a position of a portable device carried by the user by wireless communication; an operation determination unit configured to determine whether the gesture operation is executed in a situation where the portable device is present in a detection area of the detection device; and an opening and closing body control unit configured to operate the opening and closing body based on a content of the gesture operation when it is determined that the user executes the gesture operation.
