A trailer-detection system includes a radar-sensor, an angle-detector, and a controller. The radar-sensor is used to detect an other-vehicle present in a blind-zone proximate to the host-vehicle. The angle-detector is used to determine a trailer-angle relative to a host-vehicle of a trailer being towed by the host-vehicle. The controller is in communication with the angle-detector and the radar-sensor. The controller is configured to determine a trailer-presence of the trailer based on the radar-signal and the trailer-angle.

There is provided a radar device. A signal processing unit is configured to: acquire first and second estimate peaks estimated as a first peak in a rising section and a second peak in a falling section; extract first and second history peaks existing in a predetermined range from the first and second estimate peaks. A determining unit is configured to determine that the signal processing unit has erroneously extracted the first peak corresponding to a still object as the first peak corresponding to a moving object, if an accuracy of pairing of the first history peak and a second object peak existing in a predetermined range apart from the first history peak by a predetermined distance is larger than an accuracy of pairing of the first and second history peaks in a situation where a distance between the radar device and the moving object decreases.

A car door opening pre-detection system for a car includes a first detecting module, a second detecting module and a control module. The first detecting module is installed within the car. The first detecting module issues a motion detecting signal according to a result of detecting a motion of a palm. The second detecting module is installed outside the car. When the car is stopped, the second detecting module is enabled to selectively provide a first detection range or a second detection range. The control unit judges whether a car door of the car is about to be opened according to the motion detecting signal. When the car is stopped and the control module judges that the car door is about to be opened, the second detecting module provides the second detection range to detect whether there is a moving object behind the car.

A radar module determines a two-dimensional velocity vector of a heavy-duty vehicle with respect to a ground plane supporting the vehicle. The system has a radar transceiver arranged to transmit and to receive a radar signal, via an antenna array, wherein the antenna array is configured to emit the radar signal in a first direction and in a second direction different from the first direction. The radar module has a processing device to detect first and second radar signal components of the received radar signal based on their respective angle of arrival, AoA, where the first radar signal component has an AoA corresponding to the first direction and the second radar signal component has an AoA corresponding to the second direction. The processing device determines the two-dimensional velocity vector of the heavy-duty vehicle based on respective Doppler frequencies of the first and second radar signal components.

A method and system for a vehicle control system generates maps utilized for charting a path of a vehicle through an environment. The method performed by the system obtains information indicative of vehicle movement from at least one vehicle system and images including objects within an environment from a camera mounted on the vehicle. The system uses the gathered information and images to create a depth map of the environment. The system also generates an image point cloud map from images taken with a vehicle camera and a radar point cloud map with velocity information from a radar sensor mounted on the vehicle. The depth map and the point cloud maps are fused together and any dynamic objects filtered out from the final map used for operation of the vehicle.

A target vehicle speed generating device basically includes a determination unit and a correction unit. The determination unit determines whether or not a sudden change point is present in the target vehicle speed contained in the corrects the target vehicle speed so as to eliminate the sudden change point upon determining that the sudden change point is present by the determination unit. The sudden change point corresponds to a point at which acceleration changes in excess of a predetermined condition.

There is provided a radar device. A detecting unit is configured to detect a lateral location of a target relative to a vehicle equipped with the radar device, on the basis of reflected waves from the target. A selecting unit is configured to select a predetermined number of detection values from a detection value history including detection values of the lateral location detected by the detecting unit in chronological order. The predetermined number depends on a turning radius of the vehicle. A determining unit is configured to determine a definite value of the lateral location on the basis of the detection values selected by the selecting unit.

A method of determining an uncertainty estimate of an estimated velocity of an object includes, determining the uncertainty with respect to a first estimated coefficient and a second estimated coefficient of the velocity profile equation of the object. The first estimated coefficient being assigned to a first spatial dimension of the estimated velocity and the second estimated coefficient being assigned to a second spatial dimension of the estimated velocity. The velocity profile equation represents the estimated velocity in dependence of the first estimated coefficient and the second estimated coefficient. The method also includes determining the uncertainty with respect to an angular velocity of the object, a first coordinate of the object in the second spatial dimension, and a second coordinate of the object in the first spatial dimension.

An object detection device is provided. The object detection device includes an acquisition unit that uses a detection result concerning a target object to acquire an attitude and a velocity of the target object, and a filter processing unit that sets a filter applied to the velocity depending on the acquired attitude of the target object to perform filter processing.

A system and method for selectively reducing or filtering data provided by one or more vehicle mounted sensors before using that data to detect, track and/or estimate a stationary object located along the side of a road, such as a guardrail or barrier. According to one example, the method reduces the amount of data by consolidating, classifying and pre-sorting data points from several forward looking radar sensors before using those data points to determine if a stationary roadside object is present. If the method determines that a stationary roadside object is present, then the reduced or filtered data points can be applied to a data fitting algorithm in order to estimate the size, shape and/or other parameters of the object. In one example, the output of the present method is provided to automated or autonomous driving systems.
