Parking for vehicles is facilitated, monitored and controlled by using sensors to determine the availability of vacant parking spaces and by indications to alert vehicle operators at a substantial distance of the availability a vacant space. A computer controlled system monitors the sensors and controls the delivery indicator signals. Data regarding parking occupancy is used to inform drivers entering the facility and prospective users, via a telephone interface, of the availability of parking. The telephone interface further allows users to reserve parking spaces and charge the cost of the reserved space.

Technique for facilitating and monitoring vehicle parking

The present application adds detection capabilities to perceive the presence and/or measure the velocity of obstacles such as automobiles, trucks, pedestrian and other users, to vehicle lighting modules as headlamp, tail lamps, centre high mount stop lamp (CHMSL) and interior lighting to name a few, for driver assistance applications like adaptive cruise control, blind spot and pre-crash assist. For example, a Light Emitting Diode (LED) has the capability to be used as lighting source for illumination as a first function and also be pulsed or modulated as a source for the detection sub-system as a second function.

Lighting system with driver assistance capabilities

A system and a method for detecting availability of a parking space in a parking facility are provided. A first method has the steps of providing a lighting system having at least one visible-light source for illumination of at least part of the parking space. Providing an available space time-of-flight trace. Providing an availability threshold value. Illuminating the at least part of the parking space using the at least one visible-light source. Emitting a status visible-light signal from the visible-light source in the predetermined direction toward the predetermined target in the parking space. Capturing a status reflection trace at the visible-light source. Determining a time-of-flight difference value by comparing the status reflection trace to the available space time-of-flight trace. Comparing the time-of-flight difference value with the availability threshold value and determining a status of the parking space to be one of available and not available. Another method has the steps of providing a lighting system having at least one visible-light source for illumination of at least part of the parking space. Providing a camera. Providing an available space region value. Providing an availability threshold value. Illuminating the at least part of the parking space using the at least one visible-light source. Emitting visible light from the visible-light source in the predetermined direction to the predetermined target in the parking space. Capturing a reflection of the emitted visible light at the camera and determining a status region value. Determining a region difference value by comparing the status region value to the available space region value. Comparing the region difference value with the availability threshold value and determining a status of the parking space to be one of available and not available.

A multiple-field-of-view scannerless optical rangefinder operating in pulsed Time-Of-Flight operation for use in high ambient background light is described. The rangefinder comprises an optical emitter having a LED light source and driver electronics, emitting a train of light pulses having a broad field-of-illumination (FOI); a multi-channel optical receiver (MCOR) for detecting optical return signals, an overall field-of-view (FOV) encompassing each channel instantaneous FOV, the FOI encompassing the overall FOV, the multi-channel optical receiver having analog front-end electronics; an Analog-to-Digital Converter (ADC) for receiving and converting the waveforms into digital format; a control and processing unit (CPU) for generating a pulse trigger signal, sending a synchronization trigger signal to the MCOR for starting the detection of the optical return signals, and for processing the waveforms in digital format; a data interface; wherein a peak present in any of waveforms is a signature of an object detected within the instantaneous FOV.

A vehicle guidance and positioning system utilizing a laser, the emitted beam from which is directed over the path along which a vehicle is to be guided. The laser beam impinges on a target area located on the vehicle in such a manner that the impingement of the laser beam on the target is continuously observable by the vehicle's operator. The operator steers the vehicle so that the laser beam continuously impinges on the target area until the vehicle reaches a preselected position in a confined space such a garage, a drive-through service lane, a loading dock and the like.

Laser guided vehicle positioning system and method

The position indicating device is employed to assist in parking and otherwise positioning a vehicle on a supporting surface. A photoelectric control unit is mounted on an overhead structure spaced above the supporting surface and has a beam emitting device for directing a light beam downwardly for interception by the vehicle, while minimizing the likelihood of interception by pedestrians, pet animals and other moving things. The light beam is initially reflected back to a photoelectric transducer on the control unit by a reflective device or mirror. The light beam is pulsed so that the transducer supplies electrical pulses to an amplifier which is correspondingly gated. When the light beam is interrupted by the vehicle, the amplifier produces a beam interruption output signal which causes a one-shot timer to energize an alarm device, through an output relay. The operator then stops the vehicle in the desired position. The one-shot timer de-energizes the alarm device after a brief interval. Alternatively, the mirror is not employed, and the light beam is not significantly reflected back to the transducer until the light beam is intercepted by the vehicle, whereupon reflection from the vehicle produces a reflected light beam to the transducer. The corresponding pulsed signals from the transducer operate the amplifier, which is modified so that it actuates the timer, whereby it energizes the alarm device for a timed interval.
