  • Patent number: 10585169
    Abstract: A signal generating circuit includes a control voltage setting unit (CVSU) configured to set a control voltage for a chirp signal using voltage-frequency characteristics indicating characteristics of an output frequency versus voltage; a VCO configured to alter the frequency of its output signal by the control voltage; a quadrature demodulator configured to perform quadrature demodulation of the output signal of the VCO to generate an inphase signal and a quadrature signal orthogonal to each other; and a frequency detector configured to detect the frequency of the output signal of the VCO on the basis of the inphase signal and quadrature signal. The CVSU corrects the control voltage by using the voltage-frequency characteristics derived from relationships between the control voltage and the frequency of the output signal of the VCO. The VCO generates the chirp signal based on the control voltage corrected by the CVSU.

  • Publication number: 20200070818
    Abstract: Provided is a collision avoidance apparatus that can avoid a collision through both steering and braking. In a collision avoidance apparatus, a no-entry zone defining unit defines a no-entry zone for preventing a subject vehicle from colliding with an obstacle around the subject vehicle, based on obstacle information including information on a position of the obstacle and based on lane information that is information on a traveling lane of the subject vehicle. A following determination unit determines whether the obstacle is an avoidance target or a following target, based on the position of the obstacle or a position of the no-entry zone. A constraint establishing unit establishes a constraint on a state quantity or a control input of the subject vehicle to prevent the subject vehicle from at least entering the no-entry zone.
