An angle-of-view testing method for a projection display device, including setting a reference viewpoint at a same side as a reflective surface associated with the projection display device, setting a metrical marker plate with a metrical marker at another side opposite to the reflective surface at a first distance from the reference viewpoint, projecting a testing picture onto the reflective surface by the projection display device, where light of the testing picture is reflected by the reflective surface toward the reference viewpoint, such that a projected image as a virtual image of the testing picture is observed at the reference viewpoint as being projected onto the metrical marker plate, determining the coverage of the projected image with respect to the metrical marker of the metrical marker plate, and determining an angle of view of the projection display device based on the determined coverage.

A sensor test system may include a controller coupled to at least one test device and a sensor, the controller configured to receive test instructions including a plurality of test sequences, instruct at least one display unit to display an item based on the test sequences, receive response data from the test device indicative of a driver behavior, the response data including timing information and test device information, compile the response data based on the timing information and the test device information, receive sensor data acquired by the sensor during the test sequences, compare the compiled response data to the sensor data, and determine an accuracy of the sensor based on the comparison.

A hydraulic suspension system controller is disclosed, comprising a controller in operable communication with a hydraulic system of a vehicle. The controller includes at least one display, at least one indicator, and a plurality of buttons, wherein each button corresponds to a function of the controller, and wherein each function effects the hydraulic system to raise and lower at least one of a plurality of solenoids each in operable communication with a hydraulic actuator to extend or contract the hydraulic actuator. A fail-safe module is in operable communication with the controller, the fail-safe module receiving a plurality of signals from a sensor array to monitor the hydraulic system.

In a display control apparatus, it is determine whether video data transmitted to a display apparatus is reliable or unreliable. In response to determining that the video data transmitted to the display apparatus is unreliable, a predetermined process is executed.

A display control apparatus is configured to synchronize a transmission start timing to start a transmission of a video data to a display apparatus with a display operation start timing for the display apparatus to start a display operation in a display.

A vehicle system includes a human machine interface (HMI) and a controller circuit. The HMI accepts inputs from a user. The controller circuit is configured to receive a first input from the user via the HMI, anticipate a potential second input from the user via the HMI, determine potential system failures based on at least one of an operating state of the system and the potential second input, determine, based on historical data, whether an input sequence comprising the first input from the user and the potential second input from the user is likely to impact performance of the system and or one or more components of the system, and if the input sequence is likely to result in the impact to the performance of the system and or the one or more components of the system, enact at least one countermeasure to avoid or reduce the impact.

Systems, apparatuses and methods (30) may provide for technology that stores data associated with a plurality of intermediate operations in an autonomous vehicle process (32), generates a visualization output based at least partly on the data (34), and changes a magnification level of the visualization output based on user input (38), the visualization output is generated further based on parameter input and the data includes vector chart data.

A head-up display (HUD), includes an imaging unit, an optical element, which is suitable for deflecting the radiation of the imaging unit in the direction of a windshield and thereby irradiating an HUD region of the windshield in order to generate a virtual image, a positioning device, which is suitable for fixing the windshield in a defined arrangement relative to the optical element, and a camera unit, which is suitable for capturing the virtual image through the windshield from different eye positions, wherein the optical element is configured such that the entire virtual image lies within the depth of field range of the camera unit.

An in-vehicle information processing device according to an embodiment of the present technology includes a control unit. The control unit detects presence or absence of an abnormality of a first monitor that displays a first image captured by a first camera among a plurality of cameras that capture an image of a predetermined region including a rear side of a vehicle, and switches, when detecting the abnormality of the first monitor, from a first mode in which the first image is displayed on the first monitor to a second mode in which the first image is displayed on a second monitor different from the first monitor.

A vehicle is electrically connected to one or more accessories. The vehicle includes at least one controller that may be configured to identify the accessory based on accessory identification information. The controller may also be configured to provide one or more commands to control an operation of the accessory.
