Idle-State Vehicle Sensor Control for Weather-Based Function Adaptation
Solution Overview
Problem
Existing vehicle control systems fail to efficiently utilize environmental data during the idle state to adapt vehicle functions, leading to inefficiencies and potential misalignment with actual conditions, especially when parked in protected environments.
Innovation Solution
A sensor system in the vehicle detects environmental data like rain, brightness, temperature, and humidity during idle periods, storing this information for later use to adjust vehicle functions upon startup, thus avoiding reliance on external data sources and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environmental data is continuously detected during idle state, then vehicle function adaptation precision is improved, but energy consumption increases
Solution Approach 1:
The sensor system performs environmental data detection at periodic intervals during idle state rather than continuously, achieving balanced energy consumption and measurement precision. The control unit activates sensors at predetermined time points to collect environmental data while maintaining low power consumption during idle periods.
2Loss of information
If sensor system remains active during idle state, then environmental data availability is improved, but energy saving is worsened
Solution Approach 1:
The sensor system performs preliminary environmental data detection during idle state at predetermined intervals, storing data in advance for subsequent vehicle function control. This preliminary action ensures data availability when needed while limiting energy consumption through controlled activation periods.
3Measurement precision
If vehicle is woken up for sensor detection, then detection accuracy is improved, but idle state energy saving is worsened
Solution Approach 1:
The vehicle remains in idle state with periodic sensor activations rather than full wake-up, achieving measurement precision through timed sensor operations while maintaining energy savings by keeping the vehicle system dormant between detection cycles.
