Radar Mounted On And Controls Land Vehicle Patents (Class 342/70)
  • Patent number: 10355365
    Abstract: The present disclosure provides methods and apparatuses that enable a radar system to transmit radar signals into lanes on a roadway in which a vehicle may turn. For example, when a car is making a protected right turn, that is a right turn when there is another vehicle traveling in the same direction in a lane adjacent to the lane of the turning vehicle, a traditional radar may have its view of the lane in which it is turning obscured by the vehicle in the lane adjacent to the lane of the turning vehicle. By using radar deflectors strategically located near the front of the vehicle, the radar signals may be deflected at angles to avoid being obstructed by the vehicle in the lane adjacent to the lane of the turning vehicle.

  • Patent number: 10317524
    Abstract: A system and method to sense an environment based on data acquired by side looking radar. For example, a side looking radar is mounted on one or both sides of a ground-based vehicle and performs measurements from environment while the vehicle is moving. As the vehicle moves, a scan of the environment is therefore performed, wherein movement of the vehicle provides another dimension of information for the scan. In another example, the radar can further scan in the vertical plane at a fixed side looking angle to increase the field of view. A 3D map and localization can be determined from the scan.

  • Patent number: 10315649
    Abstract: A controller receives outputs from a plurality of sensors such as a camera, LIDAR sensor, RADAR sensor, and ultrasound sensor, which may be rearward facing. A probability is updated each time a feature in a sensor output indicates presence of an object. The probability may be updated as a function of a variance of the sensor providing the output and a distance to the feature. Where the variance of a sensor is directional, directional probabilities may be updated according to these variances and the distance to the feature. If the probability meets a threshold condition, actions may be taken such as a perceptible alert or automatic braking. The probability may be decayed in the absence of detection of objects. Increasing or decreasing trends in the probability may be amplified by further increasing or decreasing the probability.

  • Patent number: 10315630
    Abstract: A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.

  • Patent number: 10018502
    Abstract: A laser scanner includes: a light source; a scanning mirror that scans laser light emitted from the light source, toward a target object by oscillating about axis C; a photodetector that generates a photodetection signal upon receiving the laser light reflected from the target object; a controller that controls emission of the laser light by the light source, and that performs sampling on the photodetection signal; and a detector that detects an amount of displacement of the scanning mirror, and calculates a resonant frequency of the scanning mirror based on the amount of displacement detected. The controller determines a time at which the laser light is emitted from the light source and a time at which sampling is performed on the photodetection signal, based on the resonant frequency calculated.

  • Patent number: 9945933
    Abstract: In a frequency-modulated continuous-wave radar processing system and method, a linear frequency ramp signal is defined. The linear ramp signal is divided into a plurality of time sections. The sections of the linear ramp signal are rearranged in time such that the plurality of sections define a transmit control signal different than the linear ramp signal. A radar transmission signal is generated having a frequency varying with time according to the transmit control signal, and the radar transmission signal is transmitted into the region of interest. An intermediate frequency (IF) signal is generated using the radar transmission signal and radar receive signals received from the region of interest, a frequency of the IF signal being a difference between the frequency of the radar transmission signal and a frequency of the radar receive signals. The IF signal is low-pass filtered. Radar processing is performed on the low-pass-filtered IF signal.
