A driving assist system installed on a vehicle includes a controller. The controller executes a drawing process that controls a luminescent device to draw an assist figure with a lateral width corresponding to a vehicle width of the vehicle on a road surface along a direction of travel of the vehicle.

An LED retrofit signaling lamp is described herein. The lamp includes a lamp body, which includes a cap, a projection part, and a burner part between the cap and the projection part. Power contacts are exposed from the cap. A projection LED light source is provided in the projection part and angled to provide a projected image near to the vehicle when activated. A signaling LED light source is provided in the burner part angled to emit non-projected light via the projection part at angles that avoid the emitted light being blocked by the projection LED light source. The projection LED light source and the signaling LED light source are electrically coupled to the power contacts in parallel to each other.

A road surface state detection apparatus includes a light emitter, an optical sensor, and an electronic control unit. The light emitter is configured to project an image with visible light on a road surface below a side of a vehicle. The optical sensor is provided on the side of the vehicle and configured to receive reflected light from the projected image. The electronic control unit is configured to determine a state of the road surface based on the reflected light received by the optical sensor.

A system for automatically calibrating sensors of a vehicle includes an electronic control unit, a projector communicatively coupled to the electronic control unit, a first sensor communicatively coupled to the electronic control unit, and a second sensor communicatively coupled to the electronic control unit. The electronic control unit is configured to project, with the projector, a calibration pattern onto a surface, capture, with the first sensor, a first portion of the calibration pattern, capture, with the second sensor, a second portion of the calibration pattern, and calibrate the first sensor and the second sensor based on at least one feature sensed within the first portion of the calibration pattern and the second portion of the calibration pattern.

A lamp system for traffic lane indication using a navigation link may include a multi-function sensor sensing an environment and a line in front of a host vehicle, a line lamp generating and outputting a prediction line at a location corresponding to a line of a road, a navigation device providing location information of the host vehicle, and a vehicle controller predicting a forward line based on a line sensed by the multi-function sensor, and the location information of the host vehicle provided by the navigation device and controlling the line lamp to output the prediction line to follow the predicted forward line.

The present invention relates generally to the field of lane-keeping devices. More specifically, the present invention relates to a device that is primarily comprised of a housing, further comprised of at least one button, at least one laser emitter, a battery, and a light sensor. Further, the device is comprised of a bottom wall, further comprised of at least one fastener. The device is also comprised of a top wall that may be comprised of a solar panel to power the device. Further, the device, via laser emitter, emits a light beam directed out in front of the vehicle onto the roadway. The light beam shown on the roadway allows the driver of the vehicle to know precisely where in the lane their vehicle is located. The device further allows for the light emitter to be changed to encompass an array of different intensities and distances.

A school bus stop arm and drive unit therefor are disclosed. The stop arm includes a stop sign and a drive unit for moving the stop sign between a retracted position and a deployed position. In some embodiments the stop sign is illuminated. In some embodiments the drive unit includes a controller.

A vehicle includes a display configured to emit light to a ground surface, a communicator configured to receive a movement signal of the vehicle through communication with an external terminal, and a controller communicatively connected to the communicator and configured to determine a moving area of the vehicle based on the received movement signal of the vehicle, determine a danger area and a safety area included in the moving area, and control the display to emit light to the danger area and the safety area.

A vehicular drawing device is mounted in a vehicle and draws an indication mark of a predetermined shape on a road surface in a traveling direction of the vehicle using light. Drawing of the indication mark on the road surface is performed when a direction indicator is operating or when steering of the vehicle is being performed. Drawing of the indication mark is stopped or a direction in which the indication mark is drawn is changed when predetermined conditions are satisfied.

A lighting device, in particular a rear luminaire, for a vehicle is provided. The lighting device has a hologram and a light source for illuminating the hologram. An image, more particularly a real image, is thereby generated, which can also lie outside the physical boundaries of the lighting device.
