  • 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: 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.

  • Patent number: 10384629
    Abstract: A collision avoidance device includes a collision avoidance executor, a determiner, and a collision avoidance controller, for example. The collision avoidance executor can execute a collision avoidance function for a vehicle to avoid collision with an object to be avoided. The determiner determines, based on an operation of an accelerator pedal by a driver, whether the driver has an intention of acceleration. The collision avoidance controller inhibits execution of the collision avoidance function when the driver is determined to have the intention of acceleration. The determiner further determines, based on the operation of the accelerator pedal, whether the driver has an intention of cancelation of the collision avoidance function. The collision avoidance controller ends the execution of the collision avoidance function when the driver is determined to have the intention of cancelation during the execution of the collision avoidance function.

  • Publication number: 20170358209
    Abstract: A collision avoidance device includes, for example, a collision avoidance executor, a determiner, and a collision avoidance controller. The collision avoidance executor can execute a collision avoidance function for a vehicle to avoid collision with an object to be avoided. The determiner determines, when a driver operates a steering, whether to be able to avoid the collision with the object to be avoided, based on a turning parameter related to a turning caused by the steering. The determiner determines whether to be able to avoid the collision with the object to be avoided by determining whether a lateral acceleration or a yaw rate serving as the turning parameter is equal to or greater than a first threshold. The collision avoidance controller inhibits the execution of the collision avoidance function when the lateral acceleration or the yaw rate of a vehicle is equal to or greater than the first threshold.
