Abstract: A control mode of speed control includes a first control mode in which an actual speed is caused to follow a target speed through active use of a brake and a second control mode in which the actual speed is caused to follow the target speed while use of the brake is suppressed. An autonomous driving system changes a threshold value to a value larger than a value in the first control mode when the control mode is switched from the first control mode to the second control mode, and changes the threshold value to a value smaller than a value in the second control mode when the control mode is switched from the second control mode to the first control mode.

Abstract: A steering assistance device includes a steering wheel to which a driver of a vehicle inputs steering torque, a steering shaft connected to the steering wheel, a steering mechanism configured to convert a rotation of the steering shaft into a steering angle for steering target wheels, a steering actuator configured to drive the steering mechanism such that a steering angle corresponding to a command value is generated, a steering torque sensor configured to detect torque acting on the steering shaft, an information providing unit configured to provide road information of a scheduled passage area extending in a traveling direction of the vehicle, and an electronic control unit configured to control the steering actuator, based on an output of the steering torque sensor and the road information.
