Innovation Solution
A vehicle control device with multiple travel condition detection means that adjusts the control amount of actuators based on the reliability of detected information, restricting control in directions with low reliability and increasing it in other directions to ensure accurate travel control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the control amount of actuators is increased to improve travel control performance, then the travel control accuracy is improved, but the reliability of control decreases when detection information reliability is low
Solution Approach 1:
The control amount of actuators is dynamically adjusted based on the reliability of detection information. When detection reliability is high, the control amount is increased to improve travel control accuracy. When detection reliability is low, the control amount is restricted to maintain control reliability. This dynamic adjustment resolves the contradiction between achieving high control accuracy and maintaining control reliability under varying detection conditions.
2Reliability
If multiple travel condition detection means are used to improve detection reliability, then the reliability of detection information is improved, but the device complexity increases
Solution Approach 1:
The system incorporates a reliability determination unit that provides feedback on the reliability of detection information from multiple detection means. This feedback mechanism allows the control system to adaptively adjust control amounts based on detected reliability levels, thereby improving overall detection reliability while managing system complexity through intelligent coordination of multiple sensors.
3Reliability
If the control amount is restricted according to low reliability information, then the control reliability is maintained, but the travel control performance decreases
Solution Approach 1:
The system applies different control strategies to different actuators or control directions based on the reliability of detection information in specific directions. When reliability is low in a particular direction, control is restricted only in that direction while maintaining full control in other directions with sufficient reliability. This localized quality adjustment maintains overall travel control performance while preserving control reliability in critical areas.
