  • Patent number: 11820367
    Abstract: A turning controller for a vehicle is configured to execute: a time obtaining process that obtains collision prediction time; a lateral movement amount determining process that determines whether a target lateral movement amount is greater than or equal to a lateral movement amount determination value; and an automatic turning process that, in a case in which the collision prediction time is shorter than or equal to a determination prediction time, outputs a command for steering the front wheel to the front wheel steering device and outputs a command for steering the rear wheel to the rear wheel steering device, in order to avoid a collision between the vehicle and the obstacle; a counter-phase process in the automatic turning process in a case in which the target lateral movement amount is determined to be greater than or equal to the lateral movement amount determination value.

  • Publication number: 20230304804
    Abstract: A controller computes availability of the vehicle that indicates a range reachable by the vehicle by actuation of the actuator and generates a first travel route within a range of the availability of the vehicle, as a travel route followed by the vehicle, when the vehicle travels along a road ahead of the vehicle from a present position. When the road includes a curve and the first travel route cannot be generated within the availability range, the controller sets a target position to a position in the road located before the curve and generates a second travel route within the availability range, as the travel route followed by the vehicle, to stop the vehicle at the target position.

  • Publication number: 20230278624
    Abstract: A motion control device includes a request value acquisition unit that obtains a motion amount request value, a limit value setting unit that sets first to third motion amount limit values, a first command unit that sends a first motion amount command value based on the motion amount request value and a first motion amount limit value to a front wheel steering controller, a second command unit that sends a second motion amount command value based on a first remaining request value and a second motion amount limit value to a rear wheel steering controller, and a third command unit that sends a command corresponding to a third motion amount command value based on a second remaining request value and a third motion amount limit value to a driving controller and a braking controller.

  • Publication number: 20230242146
    Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

  • Publication number: 20230100017
    Abstract: A control device includes a model generation unit that generates a control model that formulates a task to be executed, and a task processing unit that causes the vehicle to execute the task by performing model prediction control using the control model. Assuming that a first state space is a state space of the control model used at an execution time of the first task, and a second state space is a state space of the control model used at an execution time of the second task, the task processing unit starts to cause the vehicle to execute the second task, after executing a transition process that is a process of making a value of a state variable that is commonly included in both the first state space and the second state space within a predetermined range that is allowed at the execution time of the second task.

  • Publication number: 20230001926
    Abstract: A vehicle travel control apparatus includes an information acquiring section; a determining section that determines whether a special road terrain exists; and a speed control section that controls a speed of the subject vehicle. The speed control section is further configured to: when the special road terrain exists but a preceding vehicle does not exist, increase or decrease the speed of the subject vehicle with respect to a pre-set vehicle speed in the energy efficiency zone such that the energy efficiency is improved; and when the special road terrain and a preceding vehicle exists and the speed of the subject vehicle is planned to increase in the energy efficiency zone, control the speed of the subject vehicle in an inter-vehicle distance maintenance zone such that the subject vehicle has an inter-vehicle distance to the preceding vehicle longer than a pre-set inter-vehicle distance.

  • Publication number: 20220111846
    Abstract: A controller for a vehicle is configured to execute a process that detects an anomaly of a steering device and a process that performs an automatic turning control that causes the vehicle to turn automatically along a traveling route. The controller is configured to perform the automatic turning control by controlling the steering device when an anomaly of the steering device is not detected. The controller is configured to, when an anomaly of the steering device is detected, calculate, as a predicted value, a load on the substitute device on an assumption that the automatic turning control is performed by activating the substitute device, and perform the automatic turning control by controlling the substitute device when an allowable range that is a set of values of a load allowable to the substitute device includes the predicted value.

  • Publication number: 20220089149
    Abstract: A turn assist device is configured to execute a turn assist process that assists turning of a vehicle in a case in which a steering operation of a steering wheel is in progress in a situation in which collision prediction time is shorter than or equal to determination prediction time. The turn assist process includes: an in-phase process that outputs a command for steering a rear wheel in the same direction as a steering direction of a front wheel, and a counter-phase process that outputs a command for steering the rear wheel in a direction opposite to the steering direction of the front wheel when a difference between an actual value of the lateral acceleration of the vehicle and a lateral acceleration target value exceeds a difference determination value during execution of the in-phase process.
