An authentication pattern generation unit, if a signal from a portable device is received, prompts a user who uses the portable device to perform a specific action. A checking unit determines whether or not the user has performed the specific action. If the checking unit determines that the user has performed the specific action, the checking unit authenticates that the portable device is an authorized device.

VEHICULAR FUNCTION CONTROL USING SENSING DEVICE WITH BACKLIT ICONS

A method for generating an output for controlling a vehicular function of a vehicle includes providing (i) a vehicular sensing device having at least one illumination source operable to backlight a plurality of icons, each icon representative of a respective vehicle function, and (ii) a plurality of sensors, each sensor having a respective field of sensing associated with a respective icon of the plurality of icons. With the vehicular sensing device disposed at a vehicle, and with the at least one illumination source activated to backlight the plurality of icons, the backlit icons are viewable at an exterior portion of the vehicle, and the sensors sense movement of a person's hand or foot in a field of sensing of one of the sensors, and a controller generates an output to control the vehicular function that is represented by the respective backlit icon associated with that sensor.

DOOR OPENING/ CLOSING DEVICE FOR VEHICLE

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.

Automotive Authorization Control
20210122333 · 2021-04-29 · ·

An authorization controller on a first side of a two-sided system communicates with an accelerometer on the second side for tracking the second side by inertial navigation. The authorization controller activates a radar transmitter and receiver installed on a car to include a plurality of spaced apart transmitting and receiving radar antennas to track the second side by radar. Coherent pulse or Doppler radar waveform tracks motion of an approaching user carrying a tag on the second side that is paired with the car on the first side. The authorization controller uses the radar to look for a pre-programmed pattern of user movement such as a “step in, wait, step out” pattern. Recognition of the programmed pattern activates an associated action from the authorization controller, such as opening or closing a tailgate or side door of the car. The same radar technology can be used with different programmed movement patterns to trigger the opening or closing of side doors, opening/closing of regular doors, deployment of a handicap ramp, deployment of side steps, or other chosen functions that can be initiated by electronic response. Reversing this functionality, the tag may be stationary in a garage and the car may approach the garage, causing operation of the garage door. Other functions inside a house are similarly controlled.

Control device and control method for a vehicle having an automatically opening and/or automatically closing hatch

A control device and method for a vehicle having an automatically opening and/or automatically closing flap includes an operating switch which can be operated contactlessly in the form of a proximity sensor and a programmable functional module. The method includes the following steps: firstly, an operating requirement signal is generated upon recognition of a predetermined proximity pattern consisting of the raw sensor signal of the proximity sensor for output of a resulting control signal to an unlocking and locking mechanism for the actual automatic opening or closing the valve, secondly, it is determined whether a predetermined absolute limit value of the raw sensor signal is exceeded, and thirdly, when the predetermined limiting value is exceeded, the output of the control signal is also suppressed when the operating requirement signal is generated, wherein this provision is also designated in short below as suppression mode.
