  • Publication number: 20190301601
    Abstract: A vehicle control device includes: a unit that acquires a first transmission torque transmitted in a first state in which a control pressure is controlled to a first pressure value, and a second transmission torque transmitted in a second state in which the control pressure is controlled to a second pressure value; a control unit including a storage unit that stores control data including data indicating a relationship between a friction coefficient and a surface pressure. The control unit calculates a first friction coefficient based on the data and the first pressure value, calculates a second friction coefficient based on the data and the second pressure value, calculates an estimated value of the touch point pressure based on the first and second pressure values, the first and second transmission torques, the first and second friction coefficients to control data based on the estimated value.

  • Publication number: 20190299979
    Abstract: An autonomous parking apparatus incorporated into a vehicle including an internal combustion engine, a torque converter, a transmission, a detector detecting a creep torque acting on an axle, and a microprocessor. The microprocessor is configured to perform instructing a self-parking of the vehicle, determining whether it is necessary to perform a creep torque reduction control based on a creep torque detected when the self-parking is instructed, and controlling the transmission in accordance with a determination result in the determining. When it is determined that it is necessary to perform the creep torque reduction control, the microprocessor is configured to control the transmission so as to increase engaging force of engagement elements of the transmission or change speed stage of the transmission to high speed side than when it is determined that it is unnecessary to perform the creep torque reduction control.

  • Publication number: 20190283771
    Abstract: An automated driving controller that decides an action plan for a vehicle is selectable between an ordinary driving mode and a hurried driving mode that is used in a case in which a driver is in a hurry as compared with the ordinary driving mode. In an automated driving mode the vehicle is automatically controlled, the hurried driving mode is a mode in which it is possible to arrive at a destination earlier than in the ordinary driving mode, and the driver being in a hurry appears in behaviors in the vehicles, the vehicle is accompanied with an information acquisition unit that acquires the state in which the driver is in a hurry and delivers information to the automated driving controller, and the automated driving controller selects the hurried driving mode when the information acquisition unit acquires the state in which the driver is in a hurry.

  • Publication number: 20190250607
    Abstract: A control apparatus includes a switching control unit that switches a traveling mode of a vehicle from an automated driving mode to a manual driving mode if an automated drive canceling request to cancel the automated driving mode to switch to the manual driving mode is submitted while the vehicle is traveling in the automated driving mode. The switching control unit performs transmission gear setting control in which a transmission gear of an automatic transmission is set to a highest transmission gear among transmission gears within a range of a predetermined allowable driving force in the switching from the automated driving mode to the manual driving mode.

  • Publication number: 20190225218
    Abstract: A vehicle control apparatus including an electric control unit having a microprocessor and a memory. The microprocessor is configured to perform detecting that a first wheel of one of a front and rear wheels has ridden over a level difference; calculating a target vehicle speed required for a riding over of a second wheel of the other of the front and rear wheels when it is detected that the first wheel has ridden over the level difference, and controlling the actuator so that a vehicle speed immediately before the second wheel rides over the level difference after the first wheel has ridden over the level difference becomes the target vehicle speed.

  • Publication number: 20190225237
    Abstract: A vehicle control apparatus configured to control a vehicle capable of switching between a manual drive mode for driving manually and a self-drive mode for driving autonomously. The vehicle control apparatus includes an electric control unit having a microprocessor and a memory. The microprocessor is configured to perform detecting a failure of the vehicle while traveling in the manual drive mode, and switching a drive mode from the manual drive mode to the self-drive mode when the failure is detected.

  • Publication number: 20190204828
    Abstract: If the driver operates the operation tool while the vehicle is traveling under the automated drive control, override control is performed in which the acceleration/deceleration of the vehicle is controlled according to the operation of the operation tool, when an automated drive target gear position selected based on automatic control of the acceleration/deceleration of the vehicle equals a manual drive target gear position determined according to the operation of the operation tool by the driver.

  • Patent number: 8567286
    Abstract: At pre-shift of a shift control, a line pressure control section determines a pressure raising amount ?PL of a line pressure PL on the basis of a pressure raising amount map stored in a memory, and controls a line pressure controlling linear solenoid valve so that the line pressure PL regulated by a regulator valve is raised by this pressure raising amount ?PL. For example, a control hydraulic pressure corresponding to the pressure raising amount ?PL is applied to the regulator valve from the line pressure controlling linear solenoid valve. Thus, hydraulic oil supplied from an oil pump is mostly discharged from an output port for the line pressure PL. Therefore, although there is a possibility that the line pressure PL regulated within a line pressure circuit somewhat varies when stroke of a hydraulic piston starts, a decrease of the line pressure PL is suppressed sufficiently compared with the case where the line pressure PL is not raised as a conventional manner.
