  • Vehicle front structure
    Patent number: 11731711
    Abstract: A vehicle front structure is provided for preventing a vortex from being generated between high-speed air separated from an outer edge of a deflector and low-speed air in a front wheel house due to a wind speed difference. Embodiments include a deflector disposed in front of a front wheel house projected downward from a lower surface of a bumper face. The deflector includes an air introducing section to introduce air into a space inside the deflector in a front portion of the deflector; and an intermediate-speed wind generating hole section that communicates with the air introducing section and generates an airflow at an intermediate wind speed, lower than a wind speed of air separated from deflector outer edges and higher than a wind speed of air in the front wheel house, in an area not opposing a tire in a vehicle front view of a portion immediately behind the deflector.

  • Vehicle control apparatus
    Patent number: 11719549
    Abstract: A vehicle control apparatus is configured to execute processing to calculate a correction travel route and a control target value on the basis of a target travel route under a specified constraint condition. The vehicle control apparatus calculates the correction travel route by using an evaluation function in a manner to minimize a difference of the correction travel route from the target travel route. The evaluation function is a sum that is acquired by weighting the evaluation value at each prediction point by weight coefficients. A time interval between each adjacent pair of the prediction points is set to be increased from a near side toward a far side from the vehicle. The weight coefficients are set such that weight at the prediction point on the far side from the vehicle is less than the weight at the prediction point on the near side of the vehicle.
