Vehicle and method for controlling same
The disclosure provides a vehicle and a method for controlling the vehicle. The vehicle includes: an engine; a transmission configured to transmit power from the engine to drive wheels; a deceleration factor detection device configured to detect a deceleration factor that is present ahead of the vehicle; and an electronic control unit configured to maintain a speed ratio of the transmission as a current speed ratio on condition that the deceleration factor is detected by the deceleration factor detection device, and change the speed ratio stepwise to a lower speed side than the current speed ratio and maintain the changed speed ratio, in response to a deceleration request from a driver.
SHIFT CONTROL DEVICE
A shift control device to be applied to a vehicle provided with an automatic transmission includes a detector and a shift mode control processor. The detector detects that the vehicle has passed through a tollgate through which the vehicle is able to pass without stopping. The shift mode control processor switches a shift mode of the vehicle from a first shift mode to a second shift mode the shift mode of the vehicle upon passing through the tollgate is the first shift mode and a predetermined condition regarding one or both of a speed of the vehicle and an accelerator opening degree of the vehicle is satisfied after the vehicle passes through the tollgate. In the first shift mode, a shift operation is performable by a driver, and in the second shift mode, a shift operation is performable by the automatic transmission.
Motor Vehicle Having an Electronically Controllable Parking Lock and Having an Electronically Controllable Parking Brake
A motor vehicle has an electronically controllable parking lock and an electronically controllable parking brake, which can be controlled individually or in combination. A device having an electronic control unit and a central operating element associated with the parking lock and the parking brake is provided. When the motor vehicle is at a standstill and the central operating element is actuated, the parking lock and the parking brake can be controlled in a specific type of parking-lock and/or parking-brake activation. In a first specific type, during a first actuation of the central operating element, at least the parking brake is automatically activated first. If the central operating element is then re-actuated within a predefined time window, or if the central operating element remains actuated for a predefined minimum time period, the driver is offered at least one possibility of manually selecting a specific type of parking-lock and/or parking-brake activation.
METHODS AND SYSTEM FOR SELECTING A CALIBRATION FOR A VEHICLE
Systems and methods for operating a vehicle that may be driven to or sold in different geographical locations that may have different engine emissions and fuel economy standards are described. The systems and methods may adjust vehicle operation to comply with standards that may be enforced where the vehicle is geographically located. The standards may apply to countries, treaty zones, race track areas, off-road areas, and other geographically related standards.

SHIFT OPERATION DETERMINATION APPARATUS AND SHIFT APPARATUS
A shift operation determination apparatus includes: an operation member rotatably attached to the vehicle; an operation detection section configured to detect a position of the operation member; a lock mechanism configured to regulate a rotation of the operation member; a braking operation detection section configured to detect a braking operation of the vehicle; a shift determination section configured to determine any one of a plurality of shift ranges including a first range for parking and a second range different from the first range, based on the position of the operation member; and a lock control section configured to cause the lock mechanism to regulate the rotation of the operation member from a first position corresponding to the first range to a second position corresponding to the second range when the braking operation is not detected.
Transmission control device for vehicle
The present invention provides a transmission control device for a vehicle capable of changing a threshold of a shift map for determining shift-up, thereby preventing occurrence of the shift-up during depression of an accelerator and preventing occurrence of a torque interruption. In a transmission control device for a vehicle 1 including a T/M-ECU 50 which automatically performs shift control for switching a plurality of shift gears of a transmission 20 for shift-up or shift-down, the T/M-ECU 50 has a shift threshold setting unit 54 which sets a shift threshold to be used for the shift control, on the basis of an operation plan or a surrounding state of the vehicle 1, and the shift threshold setting unit 54 sets the shift threshold to perform the shift control on the transmission 20 so as not to perform the shift-up of the transmission 20 during acceleration of the vehicle 1.
