  • Publication number: 20210316734
    Abstract: A vehicle travel assistance apparatus includes a traveling environment information acquiring unit, a preceding vehicle recognizing unit, a vehicle shadow detector, a front vehicle shadow determining unit, and a second preceding vehicle estimating unit. The vehicle shadow detector detects a vehicle shadow of a train of vehicles including a first vehicle shadow of a first preceding vehicle recognized by the preceding vehicle recognizing unit and a front vehicle shadow of a front vehicle traveling in front of the first preceding vehicle based on a brightness difference from a road surface. When the front vehicle shadow determining unit determines that the front vehicle shadow separating from the first vehicle shadow is identified from the vehicle shadow, the second preceding vehicle estimating unit estimates a position of a second preceding vehicle belonging to the train of the vehicles including the first preceding vehicle based on the front vehicle shadow.

  • Publication number: 20210316618
    Abstract: A vehicle control system is provided with a motor generator and has a function of, if a vehicle-stop brake fluid pressure at a vehicle stop timing is less a predetermined pressure necessary for holding a vehicle in a stopped state, boosting the vehicle-stop brake fluid pressure to the stop holding fluid pressure or greater to hold the vehicle in the stopped state. The system includes a first calculator, a second calculator, and a vehicle stop controller. The first calculator calculates a target driving force for the vehicle. The second calculator calculates, from the target driving force, a requested driving force for drive control of the motor generator and a requested brake fluid pressure to be used for brake control. The vehicle stop controller performs, at a timing immediately before the vehicle stop timing, a pre-boosting process of increasing the brake fluid pressure to the stop holding fluid pressure or greater.
