  • Publication number: 20230314158
    Abstract: A vehicle drive assist apparatus includes: a traveling environment information acquirer that acquires information on an area around a vehicle; an orientation detector that detects a face orientation or a line of sight of a driver; a projector that projects a course image indicating a vehicle's turning direction onto a road surface ahead of the vehicle; and a controller that sets the course image and controls the projector. The controller detects a driver's turn signal operation. Upon detecting the turn signal operation, the controller estimates a vehicle's turn position based on the face orientation or a direction of the line of sight. Upon determining, based on the information, that the turn position is not the intersection, the controller calculates a distance from the vehicle to the turn position based on the information, and set the course image indicating the turn position of the vehicle based on the distance.

    Abstract: A driving assist device includes a driving assist controller. The driving assist controller includes an oncoming vehicle detection unit, a prediction determination unit, a predicted travel region setting unit and a stop controller. The oncoming vehicle detection unit is configured to, when a vehicle enters an intersection, determine whether an oncoming vehicle going to enter the intersection is present. The prediction determination unit is configured to, when the oncoming vehicle detection unit determines that the oncoming vehicle is going to enter the intersection, determine whether a course of the oncoming vehicle is predictable based on vehicle behavior of the oncoming vehicle. The predicted travel region setting unit is configured to set a predicted travel region of the oncoming vehicle based on the vehicle behavior. The stopping controller is configured to cause the vehicle to stop outside of the predicted travel region set by the predicted travel region setting unit.

  • Publication number: 20230227026
    Abstract: A driving assist device includes a driving assist controller. The driving assist controller is configured to perform driving assistance when the vehicle changes a course by crossing the oncoming lane. The driving assist controller sets a predicted travel region based on behavior of the oncoming vehicle when the oncoming vehicle is approaching the vehicle that enters an intersection. When the vehicle enters the predicted travel region in a travel path of the vehicle, the driving assist controller determines whether there is a possibility of contact between the vehicle and the oncoming vehicle based on the predicted travel region and the travel path of the vehicle. The driving assist controller causes the vehicle to stop outside of the predicted travel region when there is a possibility of the contact.

  • Publication number: 20230227033
    Abstract: A driver assistance device acquires information about vehicle-driving environment ahead of the vehicle to detect an intersection. Upon determining that the vehicle makes a right- or left-hand turn at the intersection, the driver assistance device sets a projected course of the vehicle and recognizes a moving object ahead in a direction in which the vehicle making a right- or left-hand turn is headed. The driver assistance device calculates a movement vector from positional changes of the moving object to calculate a meeting point of a path of the object and the projected course. When an interval between times at which the vehicle and the moving object reach the meeting point is found to fall within a predetermined range, the driver assistance device determines that there is a possibility of interference between the vehicle and the moving object and then causes the vehicle to halt short of the meeting point.

  • Publication number: 20230227029
    Abstract: A vehicle traveling control apparatus includes a sensor and a traveling control processor configured to function as an identification unit and a tentative identification calculation unit. The identification unit identifies whether the target detected by the sensor is a ghost or a real object based on results of the detection for first number of measurement cycles, and if the target is the real object and a possibility that the target and the vehicle come into contact with each other is present, causes a first traveling control to be executed. The tentative identification calculation unit determines whether the target is the ghost or the real object based on results of the detection for second number of measurement cycles, and when the target is the ghost and the possibility is present, causes a second traveling control to be executed. The second number is less than the first number.
