  • Publication number: 20200130728
    Abstract: A steering system is configured such that a ratio of a turning angle change amount with respect to a steering angle change amount in a first steering angle area is larger than the ratio of the turning angle change amount with respect to the steering angle change amount in a second steering angle area, and a steering angle in the second steering angle is smaller than the steering angle of the first steering angle area. An electronic control unit of the steering system sets a delay degree of a change in turning angle with respect to a change in steering angle in the first steering angle area to be larger than the delay degree of the change in turning angle with respect to the change in steering angle in the second steering angle area regardless of a turning-over operation or a turning-back operation.

  • Patent number: 10597076
    Abstract: Provided is a steering control device (10) for a vehicle (12), including a front wheel steering device (14) and a rear wheel steering device (42). When a magnitude of a steering angle (MA) is large in a state in which rear wheels are steered by the rear wheel steering device in the same phase with respect to front wheels, the steering control device carries out calculation so as to increase a rear wheel target correction steering angle ??bt for a correction steering for the rear wheels (18RL and 18RR) toward an opposite phase direction with respect to the front wheels (18FL and 18FR) compared with when the magnitude of the steering angle is small, and controls the rear wheel steering device based on the target correction steering angle ??bt, thereby increasing a slip angle toward the inside of a turn of the vehicle.

  • Publication number: 20200062294
    Abstract: A controller includes a control circuit configured to calculate a target corresponding steered angle that is a target value of a corresponding steered angle based on the transmission ratio associated with the vehicle speed. The corresponding steered angle is a rotation angle of a rotation shaft, which is convertible to the steered angle whose magnitude is changed relative to a value indicating the steering angle. The control circuit is configured to control the actuation of the motor so that an actual corresponding steered angle is a final target corresponding steered angle that is based on the target corresponding steered angle. The control circuit is configured to calculate the target corresponding steered angle by adjusting the transmission ratio based on a value indicating acceleration or deceleration of a vehicle.

  • Publication number: 20190202492
    Abstract: A steer-by-wire system includes a steering reaction torque generation device mechanically separated from a turning device for turning wheels and configured to apply a reaction torque to a steering wheel. The steering reaction torque generation device has a duplex configuration including a first system and a second system, each system including a reaction torque motor. When both systems are normal, a control device generates the reaction torque having a normal characteristic by controlling an operation of the reaction torque motor of at least one system. In a case of single failure where one of the systems fails, the control device generates the reaction torque having a first characteristic by controlling an operation of the reaction torque motor of another of the systems. The reaction torque having the first characteristic is different from the reaction torque having the normal characteristic with respect to a same steering angle.

  • Patent number: 10086669
    Abstract: Left and right stabilizer bars are provided between left and right wheels of a vehicle. A control unit controls an actuator to control a rotation angle of the right stabilizer bar with respect to the left stabilizer bar. The control unit determines whether the vehicle is moving, whether a vehicle speed is less than a first threshold value, and whether a vehicle state is in transition from a moving state to a stopped state. A detection unit detects a control amount of the actuator. When the vehicle is moving, the vehicle speed is less than the first threshold value, the vehicle state is in transition from the moving state to the stopped state, and the control amount of the actuator is greater than zero, the control unit decreases the control amount of the actuator such that the control amount of the actuator becomes zero before the vehicle speed becomes zero.

  • Patent number: 9395781
    Abstract: An electronic device can communicate with an external device according to a predetermined method. The electronic device includes a power switch operable to receive an operation for switching on and off the electronic device, a detector operable to detect a connection between the electronic device and the external device according to the predetermined method, and a requestor operable to request the external device to supply power. When the detector detects the connection between the electronic device and the external device with the power switch being ON, the requestor does not request the external device to supply the power in an establishing process for establishing the communication with the external device. When the detector detects the connection between the electronic device and the external device and the power switch is switched from ON into OFF, the requestor requests the external device to supply the power in the establishing process.
