A driving assistance system for reversing a mining haulage vehicle, particularly for reversing a haul truck into a defined target position in a loading or dumping area, wherein the driving assistance system is configured that the target position is determined based on a logged loading tool position of the earthmoving machine, wherein steering instructions are provided to a light indicator when the transmission of the haulage vehicle is shifted to reverse.

A driving intention indicating device includes a projection system and a control unit. The projection system is arranged on a vehicle. The control unit is configured to control the projection system according to a change in a gear position of a gearbox of the vehicle. When the gear position of the gearbox of the vehicle is switched from a first gear position to a second gear position, the control unit is configured to control the projection system to project an indicating image on a road surface close the vehicle according to a moving direction of the second gear position, in order to indicate a moving direction of the vehicle from a parked position.

A motor vehicle includes a display screen viewable by a driver of the motor vehicle. A rearview camera captures images of a scene behind the motor vehicle. Means detects a location of an object behind the motor vehicle. An actuator is coupled to the rearview camera and changes a field of view of the rearview camera. An electronic processor is communicatively coupled to the display screen, the rearview camera, the detecting means, and the actuator. The electronic processor controls the actuator to change the field of view of the rearview camera dependent upon the detected location of the object behind the motor vehicle. The electronic processor presents on the display screen video content dependent upon the images captured by the rearview camera.

A vehicle for collision avoidance assistance may include: a camera to obtain an image of an object behind the vehicle, and obtain coordinates of a feature point spaced apart from the object, a controller, and a notification unit to output a collision warning. In particular, the controller sets an estimated value of a vector indicating a state of the vehicle based on coordinates of the vehicle, coordinates of the object, and the coordinates of the feature point, determine a predicted value of the estimated value of the vector based on a result of differentiating the estimated value of the vector with respect to time, correct the predicted value, determine the estimated value of the vector, and calculate a distance between the camera and the object to transmit a collision warning signal to the notification unit.

Example obstacle detection systems and methods are described. In one implementation, a method receives data from at least one sensor mounted to a vehicle and creates a probabilistic grid-based map associated with an area near the vehicle. The method also determines a confidence associated with each probability in the grid-based map and determines a likelihood that an obstacle exists in the area near the vehicle based on the probabilistic grid-based map.

An autonomous vehicle (AV) includes a radar sensor system and a computing system that computes velocities of an object in a driving environment of the AV based upon radar data that is representative of radar returns received by the radar sensor system. The AV can be configured to compute a first velocity of the object based upon first radar data that is representative of the radar return from a first time to a second time. The AV can further be configured to compute a second velocity of the object based upon second radar data that includes at least a portion of the first radar data and further includes additional radar data representative of a radar return received subsequent to the second time. The AV can further be configured to control one of a propulsion system, a steering system, or a braking system to effectuate motion of the AV based upon the computed velocities.

A collision prevention device is mounted on a vehicle and prevents collision against an obstacle by controlling a driving system of the vehicle. This collision prevention device includes an obstacle sensor, an obstacle detection area setting unit, a detector and a vehicle controller. The obstacle sensor transmits one of a light wave, a radio wave and an ultrasonic wave to a predetermined obstacle detection area, and receives a reflected wave of one of the light wave, the radio wave and the ultrasonic wave. The obstacle detection area setting unit sets the obstacle detection area of the obstacle sensor. The detector detects the obstacle in the obstacle detection area based on a detection result of the obstacle sensor. The vehicle controller controls the driving system of the vehicle based on a result of the detection of the detector, and according to the obstacle detection area set by the obstacle detection area setting unit.

A collision avoidance system includes: a radar that detects an object that is located behind a vehicle and that detects a distance to the object; a plurality of ultrasonic sensors, each of which detects the object and detects a distance to the object, the plurality of ultrasonic sensors respectively detect different detection areas; an approaching object detection unit that detects an approaching object that approaches the vehicle from among the objects; a screen estimation unit that estimates that there is a screen that blocks an approach to the vehicle from behind; and a control unit that, when the approaching object has been detected, executes driving assistance for avoiding a collision with the approaching object, and, when a distance to the approaching object is larger by a predetermined value or more than a distance to the screen, restricts or prohibits execution of the driving assistance.

A sensor has an antenna. The antenna includes a radiation source and a wave guide. The radiation source is formed on a substrate. The wave guide internally propagates electromagnetic waves radiated from the radiation source and radiates the electromagnetic waves as a beam. The wave guide has a radiation-side opening in which a first direction and a second direction are orthogonal to each other, and the second direction is longer than the first direction. In a cross-sectional shape of the beam, perpendicular to a radiation direction of the beam radiated from the wave guide, a first direction and a second direction are orthogonal to each other, and the second direction is narrower than the first direction.

A work vehicle may include a chassis, a plurality of ground-engaging devices connected to the chassis and configured to provide support and traction to the chassis along a ground surface, an operator station connected to the chassis, and a rear object detection system configured to detect a presence of an object in an area at least partially rearward of the operator station. The rear object detection system may be further configured to detect a presence of a depression of the ground surface in the area.
