Vehicle Selector Lever Integrating Start-Stop Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle operating devices require complex operations and multiple steps for driving and parking, making them less simple and efficient compared to conventional systems.
Innovation Solution
An operating device with a selector lever that includes a base element and movable operating parts, allowing for simplified operation by moving between activation and deactivation positions, with a locking device to secure the drive device in the activation state and automatically deactivate it when returning to the parking position, reducing the number of steps needed for driving and parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional operating devices are used, then the vehicle can be operated with separate controls for transmission and engine start/stop, but the operation becomes complex and requires multiple steps
Solution Approach 1:
The patent combines the transmission selector lever and engine start/stop control into a single integrated operating device. The selector lever includes operating parts that can be moved toward each other to activate the drive device, merging two separate control functions (transmission selection and engine start/stop) into one unified mechanism, thereby reducing operational complexity and the number of steps required.
Solution Approach 2:
The selector lever is designed to perform multiple functions: it selects transmission stages (parking, reverse, neutral, drive) and simultaneously controls engine start/stop operations. The operating parts on the selector lever serve dual purposes depending on their position and movement, allowing a single device to replace multiple separate controls.
2Productivity
If the start/stop function is integrated into the selector lever, then operational expenditure is reduced and operation becomes more intuitive, but the device structure becomes more complex
Solution Approach 1:
The patent integrates the start/stop function directly into the selector lever structure by providing operating parts that can be moved toward each other to activate the drive device. This merging of functions allows the same mechanism used for transmission selection to also control engine start/stop, improving operational efficiency without requiring separate controls.
Solution Approach 2:
The operating parts on the selector lever are designed to be movable relative to each other, allowing dynamic reconfiguration based on the selected transmission stage. The operating parts can be moved toward each other to activate the drive device in certain positions, providing adaptive functionality that improves operational efficiency while managing structural complexity through controlled mobility.
3Ease of operation
If operating parts are movable on the selector lever, then the drive device can be activated by moving operating parts toward each other, but the locking mechanism becomes more complex
Solution Approach 1:
The locking device is integrated with the selector lever mechanism, using the same structural elements to provide both the movable operating parts for drive activation and the locking function. The locking device works in conjunction with the selector lever positions to secure the operating parts, combining multiple functions within a unified structure rather than adding separate locking mechanisms.

AI summary
An operating device for a motor vehicle is provided. The device includes at least one selector lever, which can be moved between at least one parking position, as the first position for activating a parking lock of an automatic transmission, and at least one second position that is different to the parking position. The device includes at least two operating parts which are retained on a base element of the selector lever that can move between the positions, and which can be moved towards one another out of a deactivation position into an activation position, in order to thereby bring about a starting of a drive device of the motor vehicle, as well as a blocking device which is designed to block the operating parts in the activation position, and to bring about a movement of the operating parts out of the activation position into the deactivation position as a result of a movement of the selector lever out of the second position into the parking position.
