The vehicle comprises an auto-return shift lever which is operated to switch the shift range. When the shift lever is held at the N position for a predetermined holding period or longer during the regeneration control while the shift range is traveling in the D range, the electronic control device of the vehicle performs the braking cooperative control for gradually decreasing the regeneration torque and gradually increasing the wheel brake torque for a predetermined control period, and then switches the shift range to the N range.

Control device for vehicle

A vehicle control apparatus includes: (a) a shift control portion for controlling switching of a power transmission apparatus between a parking position and a non-parking position; (b) a fail-safe portion for executing a fail-safe operation for inhibiting an electric actuator from being re-driven, when detecting an abnormality of the electric actuator; (c) a power-supply control portion for switching a supplier of an electric power to the electric actuator, from a first power supply to a second power supply, in case of determining a power supply failure of the first power supply; and (d) an abnormality-detection stop portion configured, in case of occurrence of a power-supply failure state of the first power supply during the switching from the non-parking position to the parking position, to stop the fail-safe portion from detecting the abnormality of the electric actuator, until the electric power supplier has been switched to the second power supply.

Control apparatus for vehicle

A control device is mounted on a vehicle including a door opening and closing mechanism for opening and closing a door of an entrance and exit where a passenger gets on and off, and a shift device for changing a driving range of a transmission. The driving range is input to the control device and the control device opens and closes the door by the door opening and closing mechanism. The control device permits opening of the door when the driving range is a parking range, and prohibits a change of the driving range of the shift device when the driving range is the parking range and the door is open.

Control device for vehicle and vehicle

A vehicle includes a controller. The controller is configured to perform authentication of a portable device by communication with the portable device when startup of a system of the vehicle is instructed, when the system is off, or when the startup of the system of the vehicle is instructed and the system is off. The controller is configured to perform the startup of the system of the vehicle when the startup of the system of the vehicle is instructed, under a condition that the authentication of the portable device is successful. The controller is configured to perform reauthentication of the portable device when predetermined movement of the vehicle is detected after the startup of the system of the vehicle, and perform theft prevention processing when the reauthentication of the portable device fails.

Vehicle

A vehicle shift control device comprises: a shift position deciding portion deciding a shift position of a shift operating device based on a sensor signal output according to an operation of the shift operating device; and a drive power output command portion selecting a shift range based on a shift position determination signal output from the shift position deciding portion to cause a vehicle to run, when a communication abnormality has occurred so that the shift position determination signal is not transmitted from the shift position deciding portion to the drive power output command portion, the vehicle shift control device selecting a shift range maintained at the time of occurrence of the communication abnormality of the shift position determination signal if a vehicle speed is equal to or greater than a predetermined value, and selecting a neutral range if the vehicle speed is less than the predetermined value.

Vehicle shift control device

A shift range is selected based on a vehicle speed or acceleration of a vehicle and a shift range kept by a drive unit at the time when it is determined that there is a malfunction in shift sensors. Thus, it is possible to avoid a disabled self-propelled state resulting from a change into a neutral range through a fail-safe operation and keep limp home running.

Shift control system for vehicle and shift control method for vehicle

An ECU is connected to a multi-system shift sensor detecting a shift lever position in a shift direction associated with detection of the R position, and to a multi-system select sensor detecting a shift lever position in a select direction not associated with detection of the R position. When only one or more, but not all, of sensors in the select sensor are abnormal, the ECU controls the shift range according to the shift position detected based on the remaining proper sensor. When only one or more of sensors in the shift sensor are abnormal, the ECU maintains the current range until an operation of a shift lever is detected, and switches the shift range to the N range at the point of time of detecting an operation of the shift lever.

Vehicle control device

A shift control device for vehicle is provided capable of controlling an actuator to switch shift ranges of a transmission and switching establishment of operating states between a first operating state enabling a detection of a reference position for controlling the actuator during an initial operation of the actuator, and a second operating state disabling the detection of the reference position, besides the first and second operating states, a third operating state being able to be established with an inability to detect the reference position but with an ability to detect vehicle information; and when the second operating state is switched to the first operating state with the third operating state continuously remained, after switching from the first operating state to the second operating state, the reference position being detected again.

Shift control device for vehicle

A shift control device is provided for a vehicle of shift-by-wire type having shift operation detecting means electrically detecting a shift operation of a driver, range switching means switching a shift range in response to the shift operation of the driver, failure detecting means detecting a failure in a shift operation detection executed by the shift operation detecting means, and vehicle state detecting means detecting a vehicle state upon detection of the failure in the shift operation detection, the range switching means being switched to a fail-safe mode, when the shift operation detection is recovered from a failed state to a normal state and the range switching means is switched from the fail-safe mode to a normal control mode, a recovery condition for determining switching of the fail-safe mode to the normal control mode being altered depending on the vehicle state.

A vehicle control device includes: an abnormality detecting portion that detects an abnormality in at least part of a shift position detection portion detecting a shift position; a shift-operatoin determining portion that determines, based on a detection signal from the shift position detection portion, whether a shift operating device is shift-operated or not by a driver, and a vehicle movement prevention control portion that, in a case where a movement of a vehicle is prevented by an actuator and in a case where the abnormality in part of the shift position detection portion is detected by the abnormality detecting portion, permits the actuator to release the prevention of the movement of the vehicle if it is determined by the shift-operation determining portion that the shift operating device is shift-operated by the driver.
