摘要: A vehicle gear control method includes acquiring a driving scene image while a vehicle is driving, and performing image recognition on the acquired driving scene image to obtain a driving scene label including at least one of a road attribute label, a traffic attribute label, or an environment attribute label. The method further includes acquiring driving status data and driving behavior data corresponding to the vehicle. The driving status data indicates at least one of vehicle speed and vehicle acceleration and the driving behavior data indicates at least one of a brake control input, an accelerator control input, or a throttle opening degree. The method further includes determining a gear shifting mode based on the driving status data, the driving behavior data, and the driving scene label. The gear shifting mode controls the vehicle to drive according to a corresponding gear at a corresponding gear shifting time.

摘要: An automatic transmission includes a park rod adapted to non-rotatably lock an output shaft of the automatic transmission, an actuator adapted to drive the park rod, and an ATCU adapted to drive the actuator when a setting range of the automatic transmission is set into a P range. In a situation where an accelerator pedal is pressed on a climbing slope, driving force and gradient resistance are balanced, and a vehicle is stopped, the ATCU does not set the setting range of the automatic transmission into the P range even when a shifter is operated into the P range.

摘要: A control device for a vehicle is provided, which vehicle includes a driving source, and an automatic transmission having a torque converter provided downstream of the driving source in a power transmission path and having a lockup clutch, and an engaging element provided downstream of the torque converter in the power transmission path. The device includes a control unit which engages the engaging element in a state where the lockup clutch is engaged if an accelerator opening becomes not smaller than a predetermined opening during neutral running control in which the automatic transmission is brought into a power shut-off state during running of the vehicle.

摘要: A method for transmission upshift sequencing includes detecting a lift foot gear hold condition is met and that a current engine speed is greater than a pattern gear engine speed for the current gear. If these conditions exists then the current gear is held until a first sequence timer expires and then an upshift event occurs to a first gear having an engine speed less than the current engine speed. The first gear is then held until a at least one other sequence timer expires and, thereafter, at least one other gear is selected and held until the engine speed is less than or equal to a pattern gear engine speed.

摘要: In a transmission controller for the open-loop and/or closed-loop control of the operation of an automatic or automated manual transmission of a motor vehicle, a shifting strategy of the transmission control unit controls the operation of the transmission in an open-loop and/or closed-loop manner based on driving status data and/or driver intention data. The shifting strategy of the transmission control unit influences a gear change from a current actual gear into a target gear based on available environmental data. In the event of a required down-shift from a current actual gear into a lower target gear, the transmission control unit is configured to take into account available information relating to a traffic light status, in particular relating to a change of a traffic light status of a relevant traffic light.

摘要: An automatic transmission controller is provided, which is capable of reducing occurrence of a shift shock while improving responsiveness of a driving force. An ECU is configured to calculate a target shift time based on an input torque that is input to the automatic transmission when a gear stage is shifted from a current gear stage to a target gear stage spaced two or more stages apart from the current gear stage. The ECU is also configured to: shift the gear stage to an intermediate gear stage between the current gear stage and the target gear stage when the target shift time is not less than a predetermined value; and to shift the gear stage directly to the target gear stage when the target shift time is less than the predetermined value.
