A lane detection system for a vehicle includes at least one sensor for sensing lane markers and objects in the vicinity of a host vehicle, a driver interface in the host vehicle, and a controller having control logic. The control logic receives signals from the at least one sensor, determines a present lane of travel based on the sensor signals received, determines that a time that the host vehicle has been in the present lane of travel meets or exceeds a predetermined time, and transmits an alert signal to the driver interface in response to the time meeting or exceeding the predetermined time.

A sensing device detects an object in a blind spot in a surrounding environment of a mobile body. The sensing device includes a distance measurer, a detector, and a controller. The distance measurer acquires distance information indicating a distance from the mobile body to the surrounding environment. The detector detects the object in the blind spot. The controller controls operation of the detector. The controller detects the blind spot in the surrounding environment, based on the distance information acquired by the distance measurer. The controller controls precision at which the detector is caused to detect the object in the blind spot, according to a distance to the blind spot.

The present disclosure relates to systems and methods that facilitate a scanning light detection and ranging (LIDAR) device configured to provide an asymmetric illumination pattern. An example system includes a rotatable base configured to rotate about a first axis and a mirror assembly. The mirror assembly is configured to rotate about a second axis, which is substantially perpendicular to the first axis. The system also includes an optical cavity coupled to the rotatable base. The optical cavity includes a photodetector and a photodetector lens arranged so as to define a light-receiving axis. The optical cavity also includes a light-emitter device and a light-emitter lens arranged so as to define a light-emission axis. At least one of the light-receiving axis or the light-emission axis forms a tilt angle with respect to the first axis.

The embodiments of the present disclosure relate to a radar control device and method. Specifically, a radar control device according to the present disclosure may include a receiver configured to receive vehicle surrounding information about surroundings of a host vehicle from a radar sensor, a map generator configured to determine a measurement value of the radar sensor for an object from the vehicle surrounding information, determine a detection probability for the measurement value, and generate a predicted occupancy probability grid map based on the detection probability, and a determiner configured to determine a free space in which the host vehicle can travel based on the predicted occupancy probability grid map.

When riding a motorcycle, a vehicle in the rider's blind spot poses a hazard. A fixed range blind spot detector may not properly detect vehicles in adjacent lanes if the motorcycle is at one side or other of the lane that it is travelling in. A lane position sensor detects the position of the motorcycle with respect to the centerline of the lane in which it is travelling. Depending on the sideways position of the motorcycle within its lane, the widths of the detection zones of the blind spot detector are adjusted so that between them they cover a majority of the width of each adjacent lane.

Disclosed are: a detecting device that efficiently detects objects present around a vehicle; and a detection position calculating device. The detecting device includes: a forward detecting unit that is disposed in the proximity of a front portion of one side portion of a pair of side portions of a cab disposed at a front portion of a vehicle, and that detects an object present in a detection range spreading to the front of a detecting face facing forward from the vehicle; and a side detecting unit that is disposed in the proximity of a rear portion of one side portion of the cab, and that detects an object present in a detection range spreading to the front of a detecting face facing sideways from the vehicle. The forward detecting unit is disposed with the detecting face inclined toward one side portion side as to an orthogonal line orthogonal to a center axis of the vehicle, and the side detecting unit is disposed with the detecting face inclined toward a rear of the vehicle as to the center axis.

A tandem position sensing system includes a range sensor configured to emit a signal toward a sliding tandem and to measure a distance between the range sensor and the sliding tandem, a sensor housing configured to house the range sensor, the sensor housing having a first opening through which the range sensor is configured to emit the signal, and a coupling member attached to the sensor housing and configured to couple the range sensor housing to a body of a trailer or a chassis.

A vehicle includes a communicator that is mounted on the vehicle to perform wireless communication with a server and a controller operates the communicator to transmit an accident reception request signal and image data acquired by another vehicle to the server when the vehicle has an accident with an accident target vehicle. The controller operates the communicator to receive a fault ratio from the server when the server generates fault ratio data between the vehicle and the accident target vehicle based on the image data.

A method of identifying target-type vehicle through radar based blind spot warning (BSW) system of a host vehicle, comprising: detecting a first radar reflection point reflected by an object, said first radar reflection point being outside the BSW zone of the BSW system; setting an object area based on the distribution of groups of the first radar reflection point; assuming the object to be other vehicle based on the positional relationship between the object area and the BSW zone; detecting a second radar reflection point inside the BSW zone; and determining the other vehicle to be the target-type vehicle based on the detected second radar reflection point. The target-type vehicle is trailer or coach.

A vehicle alert device (10) executes alert control of determining, when a target is detected in a periphery of an own vehicle (C1), within a set calculation period, whether the target is an alert-target object that does not include a stationary object, determining, when the target is an alert-target object, whether the alert-target object exists in a blind spot area (RL, RR) of a driver, and alerting the driver when the alert-target object exists in the blind spot area. The vehicle alert device avoids executing the alert control when a relative speed of the own vehicle with respect to the alert-target object at a time when the own vehicle overtakes the alert-target object is equal to or higher than a predetermined threshold value. The vehicle alert device sets the predetermined threshold value to a larger value and sets the set calculation period to a shorter value, when a travel speed of the own vehicle at the time when the own vehicle overtakes the alert-target object is equal to or higher than a predetermined speed, than the predetermined threshold value and the set calculation period at a time when the travel speed of the own vehicle is lower than the predetermined speed.
