A vehicle front headlight device includes: a fixed illumination section configured to shine light toward a first illuminated region at a lower side ahead of a vehicle; a variable illumination section that selectively adopts either an illumination angle from which light is shone toward a second illuminated region further ahead of the vehicle than and at an upper side of the first illuminated region, or a depiction angle from which a depicted pattern is shone toward a depiction region nearer to the vehicle than the first illuminated region; a support member to which the fixed illumination section being attached; a retention section that retains the variable illumination section and is supported by the support member so that it can pivot about an axial direction running along a vehicle width direction; and a drive section that causes the retention section to selectively adopt either the illumination angle or the depiction angle.

A system, method and storage medium for providing an emergency lighting includes generating, by a controller, a driving control signal; receiving, by a light source, the driving control signal; and emitting, by the light source, light based on the driving control signal. Intensity of the light emitted from the light source repeatedly ramps up and ramps down with a first period based on the driving control signal.

A control device for a vehicle predicts a collision of the vehicle with an object and then actuates a drive assist device. The control device includes a collision predictor, a drive assist controller, an engine controller, a first power supply system, a second power supply system, a switch, and a switch controller. When a possibility that the vehicle will collide with the object exceeds a threshold, the collision predictor outputs a collision alarm signal. When the collision alarm signal is output during driving of the starter motor, the engine controller stops the starter motor to increase an electric potential of the second power supply system, and the switch controller turns on the switch, based on a difference in electric potential between the first and second power supply systems.

A notification device provided in a vehicle including an autonomous driving system which causes the vehicle to travel by autonomous driving and to evacuate the vehicle when a failure occurs, includes a display unit configured to display information toward an outside of the vehicle, and a display controller configured to control the display unit. The display controller causes the display unit to be turned on or flicker when a failure occurs and changes a display of the display unit in at least one of a time when an evacuation starts and a time when an evacuation is completed.

An apparatus for preventing a pedestrian collision accident, a system having the same, and a method thereof are provided. The apparatus includes a pedestrian sensing unit that senses a pedestrian moving into a dangerous area and calculates velocity and direction information of the pedestrian. A communication unit transmits the velocity and direction information of the pedestrian to a surrounding vehicle. A time-to-collision (TTC) calculating unit calculates a TTC using velocity and direction information of a subject vehicle and second velocity and direction information of the pedestrian, when the TTC calculating unit receives the second velocity and direction information of the pedestrian from another vehicle. A controller outputs based on the TTC a warning to a driver of the subject vehicle or the pedestrian.

The present invention relates to an LED safety sign system, and more particularly, to an LED safety sign system in which a transparent printed circuit board including an LED and a control box mounted with a shock-detecting sensor are connected to each other so that when a shock equal to or greater than a predetermined value is applied to the control box or an automobile accident occurs, the LED of the transparent LED safety sign board automatically emits light to cause a red-edged triangular safety sign body to be lit to display a warning sign, and thus an emergency situation is identified by a driver at a remote distance, thereby preventing additional accident risks.

The present invention relates to an aerial lift (1), which includes: a lower portion (2, 3) provided with members (7) for connecting to the ground (S); a lifting structure (4); a platform (5) supported by the lifting structure (4); and a lighting system (20) including at least one lighting device (21, 22, 23) arranged on the lower portion (2, 3) or on the platform (5), other than a driving light. The aerial lift (1) is characterised in that the lighting device (21, 22, 23) selectively generates coloured light beams, the colour of which are selected among at least two distinct colours, respectively corresponding to an emergency stop situation (C2) of the aerial lift (1) and an accident at height situation (C4) of the aerial lift (1). The invention also relates to a method for implementing such an aerial lift (1).
