摘要： 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.

摘要： An electronic control unit of a vehicle recognizes a shift position based on a user's shift operation and controls a drive device based on the shift position, and an accelerator operation, a brake operation, and a steering operation by the user. When a predetermined abnormality that the shift position is not able to be recognized has occurred, the electronic control unit sets an abnormality-time shift position based on vehicle surroundings information and controls the drive device based on the abnormality-time shift position, the brake operation, and the steering operation.

摘要： A shift control device for a vehicle, includes: a minimum vehicle speed calculator that, when it is determined that a vehicle on traveling needs to decelerate before the vehicle arrives at a forward predetermined point, calculates a minimum vehicle speed using the periphery information; a shift position determination unit that determines a target shift position; and a downshift controller that, when the minimum vehicle speed is calculated, commences a downshift from a current shift position to the target shift position. Further, the downshift controller implements first control of performing multiple downshifts from the current shift position to the target shift position such that shift timing is provided at regular intervals, or second control of performing multiple downshifts such that rotational speeds of the engine after the respective downshifts become equal to each other.

摘要： The present invention improves fuel efficiency of a vehicle and decreases a noise, by decreasing a margin value of a hydraulic pressure supplied to a hydraulic pressure control target and decreasing the hydraulic pressure supplied to the hydraulic pressure control target, when the vehicle is driven automatically. In a hydraulic pressure control device 1 for a vehicle that controls a line pressure or an operation pressure (hydraulic pressure) supplied to a clutch 40 or a transmission 41 (hydraulic pressure control target) provided in the vehicle, the hydraulic pressure control device 1 includes an operation pressure control unit 10 (hydraulic pressure setting device) that sets margin values α1 and α2 of the operation pressure (line pressure) supplied to hydraulic circuits 31 and 31 of the clutch 40 or the transmission 41, on the basis of a predetermined driving plan (refer to FIG. 2) in the case of driving the vehicle automatically.

摘要： A method for operating a hybrid transmission includes monitoring the surroundings of a motor vehicle and, based on the data ascertained within the scope of the monitoring, determining a probability of occurrence of a driving situation to be anticipated, which, upon occurring, results in a deceleration of the motor vehicle. Based on the determined probability of occurrence, it is decided whether to carry out an electrodynamic gear shift or an output-assisted gear shift in order to transfer the hybrid transmission out of an operating condition, in which a gear is engaged, into a shift condition.

摘要： The motor vehicle is configured to recognize a shift position in response to the user's shift operation of a shift lever and to control a driving system, based on the shift position and the user's accelerator operation, brake operation and steering operation. On occurrence of a predetermined abnormality that causes a failure in recognizing the shift position, the motor vehicle sets an abnormality-time shift position based on vehicle peripheral information and notifies the abnormality-time shift position. When a moving direction is set by a moving direction setting unit that is provided separately from the shift lever and that allows the user to set the moving direction, the motor vehicle resets the abnormality-time shift position based on the moving direction, and controls the driving system, based on the abnormality-time shift position, the brake operation and the steering operation.

摘要： Systems and methods for reducing perception of transitions from shifting a transmission from neutral to drive are described. In one example, the transmission is shifted from neutral to drive in response to brake pedal motion before the brake pedal is fully released so that timing of pressurizing clutches and engaging a forward gear is advanced to occur while the brake pedal is still applied.

摘要： A method is disclosed for controlling a park mode in a motor vehicle that includes a powertrain with a powerplant. The method includes identifying whether the vehicle is stopped. The method also includes identifying whether the powerplant is operating or is turned off. The method additionally includes identifying whether an operator of the vehicle is present inside or has vacated the vehicle. The method also includes commanding automatic selection of the park mode if the powerplant is turned off. Furthermore, the method includes commanding automatic selection of the park mode if the operator has vacated the vehicle, whether the powerplant is turned on and operating, or is turned off. The powertrain may include an automatic transmission operatively connected to the powerplant, and the park mode can be affected inside the transmission. A system for controlling such a powertrain via a controller programmed to execute the method is also disclosed.
