  • Publication number: 20170203757
    Abstract: A frequency of an unnecessary operation of automatic braking due to a reflected wave from a guard rail is decreased. When a collision avoidance control unit determines that an obstacle detected by a radar sensor and an own vehicle are highly likely to collide with each other, the collision avoidance control unit reads a state signal output by a parking support control unit, and determines whether or not the state signal indicates a specific state, which is a state where parallel parking support is being carried out or a state where exit support is being carried out. When the state signal indicates the specific state, the collision avoidance control unit inhibits the automatic braking.

  • Patent number: 9708003
    Abstract: When performing automatic control of a steering device that assists a host vehicle to be pulled into or out of a parking space, an electronic control unit performs the following procedure. When there is, as a path for pulling the vehicle into or out of the parking space, a path in which a predicted temperature of the steering device for when the automatic control is performed to move the vehicle along the path would be lower than an allowable upper limit value, the electronic control unit starts the automatic control to move the vehicle along the path. In contrast, when there is no path in which the predicted temperature is lower than the allowable upper limit value, the electronic control unit prohibits the automatic control.

  • Patent number: 9676414
    Abstract: A parking assistance device assists the operation of steerable wheels for the entry of a vehicle into a parking space by the automatic control of a steering device. Upon execution of the automatic control, an entry path for moving the vehicle to the parking position is calculated, and also, a target steered angle for moving the vehicle along the entry path is calculated, and the actual steered angle is detected. If the target steered angle is an angle closer to the neutral angle than the actual steered angle, then the operation of the steering wheel through the automatic control is stopped. If the target steered angle is not at an angle closer to the neutral angle than the actual steered angle, then the operation of the steering wheel through the automatic control is executed.

  • Publication number: 20160101813
    Abstract: When starting automatic pulling-in control, an electronic control unit calculates a temperature increase amount ?Ti of a motor caused by the execution of the automatic pulling-in control and a temperature increase amount ?To of the motor caused by the execution of automatic pulling-out control. Based on the current temperature of the motor, the temperature increase amount ?Ti, and the temperature increase amount ?To, the electronic control unit obtains a predicted temperature of the motor of a case in which the automatic pulling-out control is executed subsequent to the automatic pulling-in control. When the predicted temperature is lower than an allowable upper limit, starting of the automatic pulling-in control is permitted. When the predicted temperature is higher than or equal to the allowable upper limit, starting of the automatic pulling-in control is prohibited.
