A control device for a vehicle capable of switching between an automated driving mode in which driving force of a vehicle having a transmission is automatically controlled and a manual driving mode in which the driving force of the vehicle is controlled on the basis of a driver's operation on the vehicle includes: an operation element to which the driver's operation is input; and a travel control unit that outputs a command value for selecting a gear range of the transmission. The travel control unit selects which of ordinary gear change control and gear change restricting control is to be performed on the basis of an operation performed on the operation element when there is an automated driving release request in which the automated driving mode is released and the automated driving mode is switched to the manual driving mode during traveling of the vehicle in the automated driving mode.

Control device for vehicle

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.

Autonomous parking apparatus

A vehicular control apparatus includes: a drive power control unit that controls drive power from a drive unit that drives drive wheels of a vehicle; a brake switch (a brake action detection unit) that detects a brake action performed on a brake unit, the brake action including decelerating and stopping the vehicle; a wheelspin detection unit that detects spinning of the drive wheels; a time measurement unit that, when the drive wheels being stopped start to rotate, measures time elapsed since the start of the rotation; and a control unit that enables the wheelspin detection unit to perform detection after a preset detection disabled period elapses since the time measurement unit has started measuring the time.

Vehicular control apparatus

A vehicle control device performs a drive mode switching control including switching a drive mode, when a request for switching to a manual drive control is made during execution of an automated drive control, to one of a plurality of drive modes that allows a driving force to accord with a required driving force based on an operation of the driver of the vehicle, over a wide range.

Vehicle control device

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.

Vehicle controller

A control device for a vehicle capable of operating in an automated driving mode for automatically controlling at least the accelerating/decelerating control of the steering control and the accelerating/decelerating control of a vehicle includes: a route information acquisition unit; and an automated driving control unit that decides an action plan on a basis of map information, the action plan includes a target vehicle speed sequence that defines a target vehicle speed at the respective predetermined points at least on a road along which the vehicle will travel next, and the automated driving control unit calculates requested braking force that is braking force for decelerating the vehicle to target vehicle speed when the target vehicle speed is achieved by deceleration, calculates a predicted temperature of a brake device when the requested braking force is achieved, and decides a utilization proportion of the brake device for the requested braking force.

A hydraulic circuit includes a first shift valve and a second shift valve that are provided in series between a source oil path through which oil whose pressure has been regulated flows and a first clutch oil path and a second clutch oil path. The first shift valve is selectively switchable between a first switching state where a first communicating oil path and the first clutch oil path are communicated and a second switching state where a second communicating oil path and the second clutch oil path are communicated, and the second shift valve is selectively switchable between a third switching state where the source oil path and the first communicating oil path are communicated and a fourth switching state where the source oil path and the second communicating oil path are communicated.

Hydraulic circuit of driving device for vehicle

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.

Vehicle control apparatus for switching from a manual drive mode to self-drive mode

The vehicle controller performs gear position switch control in which a gear position of an automatic transmission set based on the automated drive control is changed to an upper-level gear position if the driver operates the accelerator pedal under the automated drive control.

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.

Control apparatus for vehicle

If an automated drive release request to release the automated drive mode and switch to the manual drive mode is made while the vehicle is travelling in an automated drive mode, a traveling control unit performs control that gradually shifts a vehicle driving force from the vehicle driving force in the automated mode to the vehicle driving force requested by the driver in the manual drive mode.

In order to enable a transmission to reliably perform a switching to a parking range thereof, a vehicle control device includes a shift-by-wire device which switches a shift range of a transmission mounted on a vehicle in accordance with a request by an electric signal, an acceptance unit which accepts a request for switching to a parking range of the transmission, a detection unit which detects that switching to the parking range of the transmission has been settled, and a braking device which generates a braking force when the acceptance unit accepts a request for switching to the parking range of the transmission, from the time of acceptance of the request for switching until the detection unit detects settlement of the switching to the parking range.
