  • Patent number: 12110014
    Abstract: An autonomous driving system mounted on a vehicle determines a target path based on necessary information and performs vehicle travel control such that the vehicle follows the target path. A first coordinate system is a vehicle coordinate system at a first timing when the necessary information is acquired. A second coordinate system is a vehicle coordinate system at a second timing later than the first timing. The autonomous driving system calculates, based on the necessary information acquired at the first timing, a first target path defined in the first coordinate system. Then, the autonomous driving system corrects the first target path to a second target path defined in the second coordinate system by performing coordinate transformation from the first coordinate system to the second coordinate system. The autonomous driving system uses the second target path as the target path to perform the vehicle travel control.

  • Publication number: 20240308579
    Abstract: A steer-by-wire control device according to the present invention includes a control device that controls a first motor that operates a steering wheel of a vehicle and a second motor that controls steering operation of a wheel. Before making a transition to an automatic driving mode of the vehicle, the control device applies input torque to the steering wheel by the first motor in a forward rotation direction and a backward rotation direction of rotation directions of the first motor, acquires behavior information of the steering wheel obtained by application of the input torque, and determines whether or not to estimate a control parameter of the steering wheel based on the behavior information. The behavior information includes at least one of a value of a rotation angle of a steering wheel and a value obtained by time-differentiating a rotation angle.

  • Patent number: 11524706
    Abstract: An override conciliating portion executes processing to conciliate an override request during an execution of automated driving control (i.e., override conciliation processing). In the override conciliation processing, it is determined whether or not there is the override request (step S20). If the determination result of the step S20 is positive, it is determined whether or not a second automated driving mode is selected as an operation mode (step S21). If the determination result of the step S21 is negative, acceptance processing of the override request is executed (step S22). If the determination result of the step S21 is positive, invalidation processing of the override request is executed (step S23).

  • Patent number: 11110794
    Abstract: A vehicle control apparatus executes braking assist control to decelerate a vehicle by automatic operation of a braking device. When the vehicle control apparatus obtains a deceleration request from a driver during execution of the braking assist control, while a driver request deceleration requested to the braking device by the driver is constant or in an increasing trend, the vehicle control apparatus executes first arithmetic processing to suppress a system request deceleration requested to the braking device by the braking assist control from being decreased by the braking assist control.
