The computer implemented method can determine optimum values for external parameters of the vehicle by simulating a vehicle operation across the ranges of the one or more operational parameters by solving a vehicle control problem and determining an output of the vehicle control problem based on a result for the simulated vehicle operation. A vehicle can include a processing component configured to adjust a control input for an actuator of the vehicle according to a control algorithm and based on the optimum values of the vehicle parameter as determined by the computer implemented method.

  • Patent number: 11978428
    Abstract: Systems for magnetoacoustically transferring sound across an acoustic barrier include first and second acoustic resonators positioned on opposite sides of the barrier. Each of the first and second resonators includes an attached magnet. Via magnetic coupling between the magnets, an acoustic oscillation at the first resonator induces an oscillation of the same frequency at the second resonator. Thus sound waves absorbed at the first resonator are magnetically transferred across the barrier to the second resonator, from which they are emitted.

  • Publication number: 20240140529
    Abstract: A driving assistance device includes a sensor configured to detect a moving object ahead of a target vehicle and obstacles including a first obstacle and a second obstacle, and a control device. The control device is configured to determine whether the second obstacle is present. The second obstacle is located opposite to a traveling lane of the target vehicle with respect to the first obstacle in a lateral direction and forces the moving object to move in the lateral direction toward the traveling lane due to collaborative action with the first obstacle. The first obstacle hinders the moving object from moving in a longitudinal direction. The control device is configured to relax an execution condition of steering assistance for detouring around the moving object in a case where the second obstacle is present rather than in a case where the second obstacle is not present.
