Vehicle Speed Control for Infant Head Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems do not adequately address the issue of infant safety during vehicle turns, as infants are prone to head deviation from their car seats due to lateral acceleration, leading to potential accidents and reduced ride comfort.
Innovation Solution
A method and apparatus for controlling vehicle speed and acceleration based on the state of the car seat, which automatically adjusts speed profiles to perform turning section acceleration or deceleration control, using a longitudinal acceleration correction amount calculator, speed and acceleration profile corrector, and control torque calculator to ensure the infant's head remains secured.

Engineering Contradiction Analysis
1Speed
If the vehicle performs standard turning acceleration control, then the turning maneuver is efficient and timely, but the infant's head may deviate from the car seat due to lateral acceleration
Solution Approach 1:
The system applies preliminary anti-action by detecting the car seat state and proactively adjusting the speed profile before the turning maneuver begins. The ECU calculates a corrected speed profile that limits lateral acceleration, preventing the harmful effect of head deviation before it occurs, rather than reacting after the problem arises.
Solution Approach 2:
The system changes the speed parameter dynamically based on the car seat state. When a car seat is detected, the ECU modifies the speed profile parameters (acceleration rate, deceleration rate) to reduce lateral acceleration during turns, thereby maintaining safety while still enabling turning maneuvers.
2Object-affected harmful factors
If the vehicle reduces speed and acceleration during turns to prevent head deviation, then infant safety is improved, but the turning maneuver becomes less efficient
Solution Approach 1:
The system applies dynamics by making the speed profile adaptive rather than fixed. The ECU continuously adjusts the acceleration and deceleration rates based on real-time parameters such as turning radius, vehicle speed, and car seat state, optimizing the balance between safety and maneuver efficiency for each specific situation.
Solution Approach 2:
The system changes operational parameters (speed, acceleration, deceleration rates) based on the detected car seat state and turning conditions. This allows the vehicle to maintain efficient turning performance when safe, while automatically adjusting parameters to prioritize infant safety when necessary.
3Object-affected harmful factors
If the system adjusts speed profile based on car seat state, then ride comfort and safety are enhanced, but the control system complexity increases
Solution Approach 1:
The system applies universality by integrating multiple functions into the existing ECU: car seat state detection, speed profile calculation, acceleration control, and maneuver optimization all occur within a single control unit. This multi-functionality enhances safety and comfort without requiring separate dedicated hardware systems.
Solution Approach 2:
The system applies self-service by automatically detecting the car seat state and autonomously adjusting the speed profile without requiring manual driver input or complex user interaction. The ECU self-regulates the vehicle dynamics based on the detected conditions, simplifying the user interface while maintaining sophisticated control.
