TRAVEL CONTROL APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240326872 titled 'TRAVEL CONTROL APPARATUS
The abstract of the patent application describes a travel control apparatus that can detect the surrounding environment of a vehicle and make the vehicle follow a preceding vehicle by estimating its traveling trajectory.
- Detection unit to detect the exterior environment around the subject vehicle
- Microprocessor to recognize the traveling state of a preceding vehicle and determine if it has started making a turn
- Estimation of the traveling trajectory of the preceding vehicle using a Kalman filter
- Control of the traveling actuator to make the subject vehicle follow the preceding vehicle
- Variation of the weight for the Kalman filter when the preceding vehicle starts making a turn
Potential Applications: - Autonomous driving systems - Traffic management systems - Collision avoidance systems
Problems Solved: - Improving safety on the road by ensuring vehicles follow each other smoothly - Enhancing traffic flow efficiency
Benefits: - Reduced risk of accidents - Improved traffic flow - Enhanced driving experience
Commercial Applications: Title: "Advanced Travel Control System for Vehicles" This technology can be used in autonomous vehicles, transportation systems, and fleet management services to improve safety and efficiency on the road.
Questions about the technology: 1. How does the Kalman filter help in estimating the traveling trajectory of the preceding vehicle? 2. What are the key advantages of using this travel control apparatus in autonomous driving systems?
Original Abstract Submitted
a travel control apparatus includes: a detection unit configured to detect an exterior environment situation around a subject vehicle; and a microprocessor configured to perform: recognizing, based on a detected value of the detection unit, a traveling state of a preceding vehicle on a current lane; determining, based on a recognized result in the recognizing, whether the preceding vehicle has started making a turn; estimating a traveling trajectory of the preceding vehicle through a kalman filter to which a physical quantity representing the traveling state of the preceding vehicle is to be inputted as an input value; and controlling a traveling actuator based on an estimated result to make the subject vehicle follow the preceding vehicle. the estimating includes estimating, when the preceding vehicle has started making the turn, varying a weight for the kalman filter.
