  • Patent number: 12195030
    Abstract: A respective range of environment recording sensors of the vehicle is estimated by evaluating sensor signals of the sensors to check whether the ranges of the sensors respectively is sufficient for automated driving operation. If only one of, or only a predetermined subset of, the sensors do not have a sufficient estimated range, the vehicle continues to be moved in automated driving operation maintaining a speed of the vehicle or reducing it to a predetermined limited extent. A request to take over a driving task is output instantly or after a pre-determined time delay. If all of the sensors or more or different sensors than the predetermined subset do not have a sufficient estimated range, the vehicle continues to be moved with the speed of the vehicle reduced to a predetermined more significant extent, and the request to take over the task of driving the vehicle is instantly output.

  • Patent number: 11994627
    Abstract: An example ?TOF is a flexible, small, sensor unit that uses modulated light to measure distance. The architecture of the sensor allows for many use cases. Use cases include the classic single emitter, single detector topology, but also include capability for operability as a full multi-input, multi-output (MIMO) system. In a MIMO configuration, the emitters and detectors can be arranged in a configuration similar to an RF antenna array or any number of other configurations from a single emitter/detector pair to vast dispersions of emitters and detectors. By coding the signal output by each emitter with a unique pseudo-noise (PN) or similar sequence, reflected signals received at the detector can be separated from each other, providing path distances between each emitter-detector pair. Given the robustness and noise immunity of PN sequences, this approach works well even with signal levels well below the noise floor.

  • Patent number: 11770689
    Abstract: A vehicle-to-vehicle communications system utilizes passive modulation of radar signals to communicate information between vehicles. Passive radar modulators may be provided at the rear of a forward vehicle and used to enrich radar interrogation signals from a rearward vehicle with additional information. Since radar transceivers are already located on a great deal of modern vehicles, this functionality may be easily retrofitted into many vehicles without the addition of a radar transceiver. A number of vehicles in a line of vehicles may pass information back through the line by passive modulation of radar interrogation signals from each vehicle. Accordingly, a vehicle may gain information about vehicles ahead of the one directly in front of it, thereby enabling “see through radar” functionality.

The apparatus sets a reliability of the target to be followed on the basis of the probability calculated by a probability calculating process and a determination result by a determining process, and controls acceleration of an own vehicle so that a jerk which is a differential value of the acceleration becomes smaller as the reliability of the target to be followed is lower while the target-following control process is performed.

The DISC module includes at least a first sensor system, a second sensor system, a processor, and memory. The first sensor system and the second sensor system are different types of sensor systems. The first sensor system outputs a first sensor signal, and the second sensor system outputs a second sensor signal. The DISC module can detect and track an object (or objects) based on the first sensor signal and the second sensor signal. Moreover, the DISC module can output data indicative of the object as detected. In the DISC module, the first sensor system, at least a portion of the second sensor system, the processor, and the memory are integrated on a single substrate.

  • Patent number: 11498617
    Abstract: A vehicle control method for controlling a vehicle using a vehicle control apparatus includes: a sensor configured to detect a state outside a subject vehicle; and a control device. The vehicle control method includes: executing control of recovering a travel trajectory of the subject vehicle to a target trajectory, as ordinary control, by giving a steering amount in a lateral direction with respect to a travel lane of the subject vehicle; using detection data of the sensor to determine whether or not another vehicle is traveling in an adjacent lane to the travel lane of the subject vehicle; and when determining that the other vehicle is traveling in the adjacent lane ahead of the subject vehicle, increasing a response of the steering amount to a higher response than that in the ordinary control, before the subject vehicle passes the other vehicle.

  • Patent number: 11474246
    Abstract: Provided is a vehicle tracking device capable of appropriately tracking a vehicle. The vehicle tracking device is a vehicle tracking device that tracks a target vehicle that travels at the periphery of a host vehicle. The vehicle tracking device includes: an estimation unit that estimates a rectangular frame approximating an external shape of the target vehicle on the basis of past data; and a specifying unit that specifies an advancing direction of the target vehicle on the basis of layout of contour data composed of a plurality of pieces of detection point data, which is detected by a sensor that is mounted to the host vehicle and detects a relative position of a detection target with respect to the host vehicle as the detection point data, and indicates a contour of the target vehicle, with respect to a reference side that is a side on the host vehicle side among sides of the rectangular frame along a vehicle width direction of the rectangular frame.

  • Patent number: 11414083
    Abstract: A method for avoiding a lateral collision of an ego vehicle includes monitoring a lateral area of the ego vehicle, the monitored area subdivided into at least two subareas and the subareas are at least one pre-warning area and a trigger area. The method also includes identifying a target vehicle in the pre-warning and trigger area, determining movement parameters of the ego vehicle and of the target vehicle. The ego vehicle is controlled in such a way that the distance from the target vehicle is increased. Further, the ego vehicle is controlled as a function of a residence time of the target vehicle in the pre-warning area and in the trigger area, wherein the monitored subareas are located on the lane neighboring the lane used by the ego vehicle and/or a lane adjacent to the neighboring lane.

  • Patent number: 11415994
    Abstract: A method and apparatus for planning a travelling path, and a vehicle are provided. The method includes: determining at least one reference curve covering a first length range, and selecting a target reference curve covering the first length range from the at least one reference curve covering the first length range; extracting a curve to be adjusted covering a second length range from the target reference curve covering the first length range; processing the curve to be adjusted based on a safety parameter within the second length range, to obtain an adjusted curve; and determining a travelling path covering the first length range based on the adjusted curve and the target reference curve. The complexity of an actual traffic scene is taken into account, and a travelling path planning is not affected by the accuracy of sampling points.
