Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle deceleration is not controlled based on selected driving mode, then the system complexity remains low, but the occupant comfort and transportation experience deteriorate due to inconsistent G-force profiles
Solution Approach 1:
The system changes the deceleration control parameters based on the selected driving mode. Different driving modes (e.g., sport, comfort, eco) have different target deceleration profiles, and the controller adjusts the deceleration commands to match the appropriate profile, thereby improving occupant comfort without requiring a completely new system architecture
Solution Approach 2:
The system implements feedback control by continuously monitoring actual deceleration and comparing it with the target deceleration for the selected driving mode. The controller adjusts the deceleration commands based on the difference between actual and target values, ensuring consistent G-force profiles while maintaining a manageable control system
2Manufacturing precision
If deceleration control signals are adjusted based on sensor data and feedback, then the deceleration precision improves, but the control system complexity increases
Solution Approach 1:
The system uses feedback from sensor data to continuously monitor actual deceleration and compare it with the target deceleration. The controller adjusts the deceleration control signals based on this feedback to achieve precise deceleration matching the selected driving mode profile
Solution Approach 2:
The system replaces complex mechanical deceleration control mechanisms with electronic control signals and software-based feedback algorithms. This substitution achieves high precision deceleration control while keeping the physical system relatively simple

AI summary
A device and method for a controlled deceleration based on a selected vehicle driving mode are disclosed, in which upon sensing a deceleration of a vehicle, a plurality of deceleration control signals based on a deceleration target for the selected vehicle driving mode are produced. At least one of the plurality of deceleration control signals are transmitted to prompt a controlled deceleration of the vehicle to correspond with a deceleration target for the selected vehicle driving mode. The method receives sensor data relating to the deceleration of the vehicle, and compares at least some of the sensor data with the deceleration target to generate a deceleration feedback signal. The method provides for adjusting the plurality of deceleration control signals based on the deceleration feedback signal to effect the controlled deceleration.
