The present disclosure relates to a control device and method for estimating a drivable space in a surrounding environment of a vehicle. In particular, the disclosure relates to a 'free space estimation' solution with reduced validation effort. The control device includes one or more processors adapted to obtain sensor data, determine a surface flatness MF and a surface texture MR of at least one portion of the surrounding environment by means of two independent algorithms, and defining a drivable space based on obtained values.

Method and system for estimating a drivable surface

A vision system () for a motor vehicle including an imaging system () adapted to capture images from a surrounding of the motor vehicle and a data processing device () establishing an object detector () adapted to detect an object in images captured by the imaging system () through image processing. The object detector () includes a wheel detector () adapted to detect a wheel (), a wheel-like structure, or a characteristic part thereof, of another vehicle.

Vision system and method for a motor vehicle

A method and system for indirect tire pressure monitoring of tires of a vehicle is described. The method may include providing a tire classification database indicating at least one classified tire type. The method may also include determining a vehicle tire type for the vehicle on the basis of vehicle data in including information on at least one tire currently used with the vehicle, and determining whether the vehicle tire type can be associated to one of the at least one classified tire type. The method may also include, in the case an association is determined, monitoring tire pressure according to the associated classified tire type.

Tire pressure classification based tire pressure monitoring

The invention provides a system, a method and a computer program of estimating tire pressure deviations in a number of tires of a vehicle wherein a plurality of possible constellations of one or more pressure deviating tires exists. The system comprises a plurality of pressure deviation detectors (), wherein each of the detectors () is adapted to detect at least one of the pressure deviating tire constellations. The system further comprises an output unit () which is adapted to provide for a warning if one of the pressure deviation detectors () detects at least one of the pressure deviating tire constellations.

System, method and computer program of estimating tire pressure deviations

The invention is directed to a system, a method and a computer program including program code for carrying out the method, when executed on a processing system, of estimating a tire pressure deviation of a vehicle's tire (). The system includes an input section () adapted to receive as an input signal a vehicle signal, a calculation section () adapted to calculate at least one shape factor of a resonance peak associated with the vehicle signal spectrum () on the basis of the input signal, and a determination section () adapted to derive, depending on said at least one shape factor, a tire pressure signal indicative of a tire pressure deviation within the vehicle's tire ().

Method, system and computer program for estimation of the pressure

In indirect tire pressure monitoring of tires of a vehicle, the following steps and means to carry out the same, respectively, are contemplated:&#x2014;providing a tire classification database indicating at least one classified tire type;&#x2014;determining a vehicle tire type for the vehicle on the basis of vehicle data in including information on at least one tire currently used with the vehicle,&#x2014;determining whether the vehicle tire type can be associated to one of the at least one classified tire type; and&#x2014;, in the case an association is determined, monitoring tire pressure according to the associated classified tire type.

An imaging apparatus including an infrared video camera. The infrared video camera includes a sensor array operable to produce successive video images in the form of pixelated two-dimensional images. The imaging apparatus further comprises a processing arrangement operable to reduce or increase the overall brightness of an image in dependence upon the overall brightness of the pre-enhanced image and the overall brightness of the preceding enhanced image, so that the change in the overall brightness (DC-level) between the enhanced image and the preceding enhanced image is decreased.

Imaging apparatus

Methods and systems for mitigating undesirable video flash in infrared camera systems are disclosed. A frame of video can be stored in a buffer and information related to the frame of video can be processed prior to displaying the video such that the processed information facilitates display of the video substantially without flashing. A display of a non-flashed frame can be frozen while a flash event would otherwise cause a flashed frame to be displayed. The shift in a histogram caused by a flash event or some portion thereof can be subtracted from pixels of an image. Thus, image quality can be substantially enhanced.

Methods and systems for detection and mitigation of image-flash in infrared cameras

A method of estimating the occurrence of a specific tire pressure deviation between actual and nominal pressure values for one or a plurality of wheels (i) is provided. One or more wheel radius analysis measurement values (&#x394;R) are subsequently obtained from a wheel radius analysis component (), wherein the wheel radius analysis measurement values (&#x394;R) are related to single wheel radius values (&#x394;r) of which each is indicative of the wheel radius of a particular wheel (i). One or more wheel vibration data values (&#x394;&#x192;) are subsequently obtained from a wheel vibration analysis component (), wherein each of the wheel vibration data values (&#x394;&#x192;) is indicative of a vibration phenomena in the time dependent behavior of the rotational velocity of a particular wheel (i). One or more tire pressure output values (&#x3b7;, &#x394;p) are calculated on the basis of both the wheel radius analysis measurement values (&#x394;R) and the wheel vibration data values (&#x394;&#x192;) wherein each tire pressure output value (&#x3b7;, &#x394;p) is indicative of the specific tire pressure deviation for a particular wheel (i).
