  • Patent number: 11975719
    Abstract: A traveling control apparatus that allows lane changing due to a driver's steering intervention while continuing lane maintenance control includes an electronic control unit. The electronic control unit sets a target trace along a lane in which a vehicle is traveling, determines a target steering angle of the vehicle based on the target trace and a lateral position of the vehicle, applies control torque to a steering shaft of the vehicle based on the target steering angle, resets, in response to a change in the lateral position due to the driver's steering intervention which exceeds the control torque and entrance of the vehicle into an adjacent lane, the target trace to the adjacent lane, and determines, using a gradual changing function, in response to the resetting of the target trace, the target steering angle by changing the target steering angle at the time of the resetting.

  • Patent number: 11977153
    Abstract: An object detection apparatus detects an object in a vicinity of a moving body in a state of being mounted to the moving body. The object detection apparatus measures a reverberation frequency that is a frequency of a reverberation signal that is generated in a transceiver that externally transmits a transmission wave that is an ultrasonic wave and receives a reception wave that includes a reflected wave of the transmission wave from the object. The object detection apparatus detects a specific segment that is an occurrence segment in which occurrence of beat that is attributed to a plurality of reverberation frequency components is confirmed in the reverberation signal, or a non-occurrence segment in which the occurrence of beat does not significantly occur. The object detection apparatus sets a measurement segment in which the reverberation frequency is measured in the non-occurrence segment based on a detection result of the specific segment.

  • Patent number: 11971439
    Abstract: A fault detection device executes a test signal supply process for changing a frequency of a carrier wave within a frequency range predetermined as a range of a resonance frequency of an antenna, modulating the carrier wave with a test signal as an input signal, amplifying the carrier wave that is modulated, and supplying the carrier wave that is amplified as an output target signal to the antenna. While executing the test signal supply process, the fault detection device measures an antenna current corresponding to the frequency each time the frequency of the carrier wave is changed The fault detection device detects a fault caused by a difference or a change in a characteristic of the antenna by using a value of the antenna current on a larger side among the antenna currents measured during the test signal supply process.
