摘要： A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).

摘要： The disclosure relates to a dual-speed final drive control method and terminal device, and a storage medium. The method includes: when an absolute value of a gradient value of a road ahead is greater than a gradient threshold, determining, according to the gradient value, whether the road ahead is an uphill section or a downhill section, thereby controlling all gears of a transmission to correspond to a higher final drive ratio or a lower final drive ratio in the dual-speed final drive. The disclosure can make use of the dual-speed-ratio final drive to the greatest extent to improve the economy in energy consumption of the entire vehicle.

摘要： Disclosed is a method for determining a position of a motor vehicle by means of a location device of the motor vehicle. First, a first position (x1) related to an installation point of the location device in the motor vehicle is determined. In order to determine a position suitable for controlling the motor vehicle, with reference to the said first position (x1) a second position (x2) related to a center of gravity of the vehicle is determined, in that the first position (x1) is offset by a distance (a) between the said installation point of the location device and the center of gravity of the vehicle.

摘要： A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.

摘要： In a method of controlling an electronic parking brake system to overcome an existing problem occurring in drive away release (DAR) mode, a control unit monitors whether or not a gear change signal is input in a vehicle stopped state, a P position state, or a parking brake applied state. When the gear change signal is input, an accelerator pedal input value of a driver is compared with a predetermined pedal input set value while a gear position of a transmission is maintained in the P position. When the accelerator pedal input value does not exceed the predetermined pedal input set value, a control operation is performed for automatic releasing of a parking brake. When a set time has passed after start of the control operation for the automatic releasing, a control operation of changing the gear position to the D position or the R position is performed.

摘要： An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data of an exterior environment of a vehicle. The processor may be configured to process the pixel data arranged as video frames, perform computer vision operations to detect objects in the video frames, extract characteristics about the objects detected, determine driving conditions in response to an analysis of the characteristics and generate a control signal. The control signal may be configured to perform a gear shift. The driving conditions may be used to predict a future drivetrain configuration of the vehicle. The gear shift may be performed if a comparison of the future drivetrain configuration with a current drivetrain configuration of the vehicle meets a threshold condition. The gear shift may not be performed if the comparison does not meet the threshold condition.

摘要： The present invention realizes a vehicle control device that, even when power characteristics of a power generation device and a power transmission device changes, senses degradation of vehicle components, corrects a drive instruction to the power transmission device, and is thereby capable of stabilizing vehicle behavior over a long term. The present invention, in a predetermined vehicle environment state, measures fluctuation in drive power and acceleration in a transient region by using vehicle behavior sensors 4, performs comparison with a reference fluctuation, and thereby senses degradation of vehicle components. The drive instruction to the transmission 16-side is corrected in accordance with the degradation of vehicle components that is sensed. Thus, it is possible to stabilize vehicle behavior (performance) over a long term even when, during automated driving, the power characteristics of the drive power source and the transmission 16 change due to factors such as time degradation of vehicle components.

摘要： Techniques related to vehicle operation. A processor determines that at least one condition is met related to a vehicle. In response to the at least one condition being met, the processor generates a natural language output having a query. The processor determines that an affirmative response to the query is received and causes a downshift of a transmission of the vehicle in response to the affirmative response.

摘要： Transmissions, control systems for transmissions, and methods of operating transmissions are disclosed herein. A transmission includes an input shaft, an output shaft, one or more clutches, and a control system. The input shaft is configured to receive rotational power supplied by a drive unit. The output shaft is coupled to the input shaft and configured to provide rotational power supplied to the input shaft to a load. The one or more clutches are coupled between the input shaft and the output shaft to selectively transmit rotational power between the input shaft and the output shaft in one or more operating modes of the transmission. Each of the one or more clutches is selectively engageable in response to one or more fluid pressures applied thereto. The control system is configured to control operation of the one or more clutches to select the one or more operating modes of the transmission.
