Motor Vehicle Transmission Dynamic Gear Subset Selection

The patent divides the total set of driving gears into a subset that is actually made available for selection, segmenting the gear set based on current operating conditions. This segmentation approach allows the system to maintain adaptability across different terrains while reducing the complexity of gear selection by only presenting relevant options to the driver or control system.

The patent dynamically determines which driving gears are made available based on real-time state variables such as ground slope, transmission temperature, and vehicle speed. This dynamic adaptation allows the transmission system to adjust the available gear set according to current operating conditions, maintaining versatility while simplifying control at any given moment.

The patent prevents potentially harmful abrupt gear shifts by preemptively restricting the available gear set based on current state variables. By determining which gears should not be made available before the driver can select them, the system avoids situations where inappropriate gear selections would cause uncomfortable or damaging shifts, thus protecting driving comfort while maintaining necessary versatility.

The system continuously monitors state variables such as ground slope, transmission temperature, and vehicle speed, and uses this feedback to dynamically adjust which driving gears are made available. This feedback mechanism ensures that only gears appropriate for current conditions are presented for selection, preventing abrupt shifts and maintaining driving comfort while preserving gear selection versatility when conditions permit.

The patent employs dynamic determination of the available driving gear set based on real-time state variables including ground slope, transmission temperature, and vehicle speed. This dynamic approach allows the system to adapt the available gears to varying conditions while maintaining driving comfort, as the restriction of gears is not fixed but adjusts automatically when conditions change, thus resolving the contradiction between comfort and adaptability.

The system changes the parameter of available gear selection based on state variables. When conditions such as ground slope or temperature change, the set of available driving gears is re-evaluated and adjusted accordingly. This parameter-based adaptation ensures that driving comfort is maintained through appropriate restrictions while adaptability is preserved through automatic adjustment when operating conditions change.

The patent prevents unnecessary gear changes that would increase transmission wear by preemptively restricting the available gear set based on current state variables. By determining which gears are inappropriate for current conditions before they can be selected, the system avoids unnecessary gear engagements and disengagements, thereby reducing transmission wear while maintaining the completeness of gear options when conditions are suitable.

The system uses feedback from state variables such as ground slope, transmission temperature, and vehicle speed to continuously adjust which driving gears are made available. This feedback mechanism prevents unnecessary gear changes by only presenting gears that are appropriate for current conditions, thereby reducing transmission wear while preserving the completeness of gear options when operating conditions permit their use.
