Dynamic Blind Spot Detection Cycle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pedestrian detection systems face challenges in accurately tracking the behavior of pedestrians or vehicles in a driver's blind spot while managing battery power consumption, as short communication cycles enhance tracking accuracy but increase power consumption, and longer cycles compromise tracking accuracy.
Innovation Solution
A moving body detection system that adjusts communication cycles between a vehicle and a mobile phone terminal, setting longer cycles when a pedestrian or vehicle is not in the blind spot and shorter cycles when they are, using a first terminal control device, a reception device, and a main control device to determine the blind-spot condition and adjust communication accordingly.

Engineering Contradiction Analysis
1Measurement precision
If the communication cycle between the vehicle and mobile phone terminal is set to a short cycle, then the behavior of moving bodies can be accurately tracked, but the electric power consumption of batteries increases
Solution Approach 1:
The communication cycle is made dynamic rather than fixed. The control device adjusts the communication cycle length based on real-time detection of moving bodies in blind spots. When a moving body is detected, the cycle is shortened to improve tracking accuracy; when no moving body is present, the cycle is lengthened to reduce power consumption. This dynamic adaptation resolves the contradiction between tracking accuracy and power consumption.
Solution Approach 2:
The system changes the parameter of communication cycle length based on detection results. By monitoring whether moving bodies are present in blind spots and adjusting the communication cycle parameter accordingly, the system achieves optimal balance between tracking precision and energy efficiency under different operational conditions.
2Duration of action of moving object
If the communication cycle is lengthened to reduce power consumption, then battery life is extended, but the behavior of moving bodies cannot be accurately tracked
Solution Approach 1:
The communication cycle duration is dynamically adjusted based on situational needs. The system extends the communication cycle only when it is safe to do so (no moving bodies in blind spots), thereby extending battery life without compromising safety. When moving bodies are detected, the system automatically shortens the cycle to maintain accurate tracking.
Solution Approach 2:
The system modifies the communication cycle parameter according to detection outcomes. By changing the cycle length parameter from short to long based on whether moving bodies are present, the system extends battery life while preserving tracking accuracy when needed.

AI summary
A moving body detection system detects a moving body that is present in a blind spot of a driver of a host vehicle. A main control device of the moving body detection system executes a first terminal signal acquisition process for acquiring, as a first terminal signal, a signal that a reception device has received from a first terminal control device. When the first terminal signal is acquired by the process, the main control device determines whether a blind-spot condition that a moving body is present in the blind spot is met based on the acquired first terminal signal. The main control device executes the process on a first cycle when it is determined that the condition is not met, and executes the process on a second cycle that is shorter than the first cycle when it is determined that the condition is met.
