  • Publication number: 20220083053
    Abstract: A vehicle control system comprises a portable terminal and a vehicle including a communication device and a drive device. When the drive device is in a non-actuation state and the communication device is in an inactivated state, the vehicle changes a state of the communication device from the inactivated state to an activated state when an activation condition is satisfied. The activation condition is satisfied when a user holding legitimate qualification exists within a communication possible range. When the drive device is in the non-actuation state, the vehicle changes the state of the communication device from the activated state to the inactivated state when an activation stop condition is satisfied. The activation stop condition is satisfied when an activation period in which the communication device is in the activated state reaches a predetermined period.

  • Patent number: 9828028
    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.

  • Patent number: 9751562
    Abstract: A park exit assist system includes an electronic control unit. The electronic control unit is configured to detect a situation around a host vehicle parked or stopped in a parking/stopping area on a roadside. The electronic control unit is configured to calculate, on the basis of a detected result of the situation around the host vehicle, a park exit guidance path along which the host vehicle is moved out of the parking/stopping area to a traffic road and in which a steering angle becomes neutral at the time when a roadside front end of the host vehicle advances into the traffic road. The electronic control unit is configured to guide the host vehicle from the parking/stopping area toward the traffic road by at least executing steering control along the park exit guidance path.

  • 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.
