  • Patent number: 11967912
    Abstract: An object of the present invention is to provide a motor control device capable of estimating a delay with high accuracy even in a case where there is a fluctuation in disturbance torque or delay time and of suppressing the influence of the delay. For this end, the present invention includes a motor MTR, an ECU 2 that controls the rotation of the motor MTR, and an ECU 1 that sends a torque command to the ECU 2 based on a command value. The ECU 1 includes a disturbance estimation block 100 and a delay estimation block 200. The disturbance estimation block 100 estimates disturbance torque (?d) using a torque command input to the ECU 2 and a feedback value of the motor MTR. The delay estimation block 200 estimates a delay using a torque command output from the ECU 1, the feedback value of the motor MTR, and the disturbance torque (?d).

  • Patent number: 11958459
    Abstract: An object of the present invention is to appropriately control a clearance amount by correcting an estimation error of a contact position caused by a delay time difference between output signals of sensors, and to establish both improvement of fuel efficiency due to prevention of drag of a brake pad during non-braking and reduction in response time during braking. A brake system includes a brake disc, a brake pad, a piston, a drive mechanism, a position sensor that detects a position of the piston, a thrust sensor that detects a thrust by which the brake pad presses the brake disc, and a brake control unit that adjusts a braking force by controlling the drive mechanism.

  • Patent number: 10614322
    Abstract: In an object recognition device, a reliability setting unit sets object presence reliability indicating the reliability of whether or not an object is present with respect to the surrounding area of a host vehicle. Then, a grouping unit groups the reflection points based on the object presence reliability in the area between the reflection points. For this reason, for example, even though two objects are adjacent to each other, in a case where the object presence reliability in the area between the reflection points of one object and the reflection points of the other object is low, the reflection points of the two objects can be separately grouped without being grouped into a single group. As a result, since it is possible to avoid mistakenly recognizing a plurality of objects in a single object, recognition accuracy of the object can be improved.

  • Patent number: 9718469
    Abstract: An object of the invention is to provide, in a vehicle driving assistance system that provides assistance to avoid a collision between a host vehicle and a three-dimensional object causing an obstruction, a technique for avoiding assistance in which the host vehicle is guided to a region where the presence of a three-dimensional object is unclear. To achieve this object, according to the invention, a grid map, by which an avoidance region in which a three-dimensional object exists, an unclear region in which the existence of a three-dimensional object is unclear, and a safe region in which no three-dimensional objects exist can be distinguished, is created. When the avoidance region exists on the advancement path of the host vehicle, a route that can avoid the avoidance region and passes through the unclear region for a distance not exceeding a threshold is specified, whereupon a steering angle is controlled to cause the host vehicle to travel along the specified route.

  • Publication number: 20160214612
    Abstract: In a case where it is determined that a merging travel control cannot be executed, a host vehicle is caused by a stop control unit to stop in a travelling lane toward a boundary line between the travelling lane and a merging destination lane. For this reason, the possibility increases that the range, over which the driver of the host vehicle can directly view the merging destination lane from the side window, will widen. Therefore, when the driver of the host vehicle restarts the host vehicle by the manual driving, it is possible to improve the easiness of checking the status in the merging destination lane.
