Vehicles and methods of operating vehicles are disclosed herein. A vehicle includes a main frame, a work implement, and a control system. The work implement is supported by the main frame and configured to carry a payload in use of the vehicle. The control system is supported by the main frame and configured to control operation of the vehicle. The control system includes a payload measurement system configured to provide payload input indicative of a variable payload carried by the work implement in use of the vehicle and a controller coupled to the payload measurement system.

A construction machine in the form of a road paver or feeder vehicle includes a chassis and a hopper, wherein at least one lighting arrangement is mounted on the chassis. The lighting arrangement comprises at least one light source, and the lighting arrangement is configured to illuminate an area in front of the construction machine in the direction of travel. The construction machine further has an object detection system for detecting an object located in front of the construction machine in the direction of travel, and the illumination emitted by the lighting arrangement can be changed as a function of the detection of an object by means of the object detection system.

Provided is an optical axis adjustment device for a vehicle headlamp. The optical axis adjustment device adjusts an optical axis of a headlamp unit to be mounted in a vehicle, and the optical axis adjustment device includes: an engine temperature acquirer; a displacement amount calculator; a speed information acquirer; and an optical axis adjuster. The engine temperature acquirer acquires a temperature in an engine compartment of the vehicle. The displacement amount calculator calculates a displacement amount of the optical axis based on the acquired temperature. The speed information acquirer acquires speed information including a travel speed and a travel time of the vehicle. The optical axis adjuster adjusts the optical axis of the headlamp unit on a basis of the calculated displacement amount and the acquired speed information.

An electrical device controller includes a processor, and a memory for storing a program executed by the processor. The processor controls the electrical device in multiple operation modes including an automatic mode which automatically changes the operation state of the electrical device and a stop mode which stops the electrical device, controls the electrical device in an operation mode specified with an operating member operated by an occupant when the vehicle is manually driven, controls the operation state of the electrical device in the automatic mode regardless of the operation mode specified with the operating member when the vehicle is autonomously driven, and sets the operation mode of the electrical device at least temporarily to the stop mode when the operation mode specified with the operation member is switched to the stop mode from an operation mode other than the stop mode, when the vehicle is autonomously driven.

Disclosed herein is a vehicle that includes a headlamp configured to irradiate light forward, a plurality of suspensions coupled to each wheel of front wheels and rear wheels of the vehicle, a plurality of suspension sensors for detecting a height of each suspension of the plurality of suspensions, respectively. The vehicle may include a controller electrically connected to the headlamp, the plurality of suspensions, and the plurality of suspension sensors. In various embodiments, the controller is configured to receive a height value of each suspension of the plurality of suspensions from a corresponding sensor of the plurality of suspension sensors, and adjust a light irradiation angle of the headlamp by comparing the height values of the plurality of suspensions with a predetermined reference height.

An illumination apparatus that illuminates an illumination zone having a first direction and a second direction crossing the first direction is provided with a light source to emit a coherent light beam, and a diffraction optical device to diffract the coherent light beam incident from the light source. The diffraction optical device diffracts the incident coherent light beam so that a width of the illumination zone in the second direction gradually becomes wider along the first direction of the illumination zone from a nearer side to the diffraction optical device.

In a motor vehicle having motor vehicle exterior lighting devices and an operator control device, the following lighting modes of the motor vehicle exterior lighting devices can be set: deactivated, parking light, daytime running light, forwarding lighting, and automatic mode in which the motor vehicle exterior lighting devices are operated by an automatic forward light controller. The operator control device has a single monostable operator control element by which the lighting modes can be set; or the operator control device has a monostable operator control element by which the deactivated, parking light, daytime running light and forward lighting lighting modes can be set. The operator control device has a pushbutton key or a toggle lever by which the automatic mode can be set.

A method for adjusting a light-level of at least one headlamp for a vehicle. The method includes a reading in; a determining; an ascertaining; and a providing. In the reading in, a position-signal is read in, which represents the current-position of the vehicle. In the determining, a topography-signal is determined using the position-signal, which represents a stored item of information about a roadway-topography at the current position, especially in the case of a curvature and/or a drop of a roadway. In the ascertaining, an angle of inclination of the headlamp to be adjusted for the optimal illumination of the roadway in front of the vehicle is ascertained using the topography-signal. In the providing, an actuating-signal is provided for an adjustment mechanism of the headlamp using the ascertained-angle of inclination to tilt the headlamp to the ascertained-angle of inclination so that the light level of the headlamp is adjustable.

An illumination apparatus that illuminates an illumination zone having a first direction and a second direction crossing the first direction is provided with a light source to emit a coherent light beam, and a diffraction optical device to diffract the coherent light beam incident from the light source. The diffraction optical device diffracts the incident coherent light beam so that a width of the illumination zone in the second direction gradually becomes wider along the first direction of the illumination zone from a nearer side to the diffraction optical device.

The invention relates to a vehicle comprising a chassis which has a longitudinal axis and which is supported by wheels; a cab mounted on the chassis, the cab including two side walls; a wind deflecting assembly comprising at least two side deflector panels, each side deflector panel having a front edge linked to a rear portion of the corresponding cab side wall and a rear edge, and extending vertically over at least part of the height of the corresponding cab side wall rear portion; and at least one lighting assembly which is mounted on a side deflector panel and which includes at least a working lamp configured to illuminate an area located rearward of the cab.
