Vehicle Steering Angle Storage for Smooth Resume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems face challenges in ensuring a vehicle smoothly resumes travel in the desired direction after a stop, particularly when the vehicle has been stationary for an extended period.
Innovation Solution
A vehicle control apparatus and method that generates a trajectory for future positions of the vehicle, controls its travel based on this trajectory, and stores steering component information when stopped, allowing for precise determination and maintenance of the steering angle upon resuming travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops during traveling, then the vehicle can rest or wait, but the vehicle cannot smoothly resume travel in the desired direction
Solution Approach 1:
The system performs preliminary actions by storing steering component information (such as steering angle) in the storage unit before the vehicle stops. When the vehicle resumes travel, this pre-stored information is retrieved and used to determine the initial steering angle, enabling smooth resumption without requiring the driver to re-adjust the steering wheel.
Solution Approach 2:
The system creates a copy of the steering component state (steering angle information) and stores it in the storage unit. This copied information is then used to restore the steering state after stopping, allowing the vehicle to resume in the desired direction without requiring the original steering input.
2Adaptability or versatility
If steering angle is re-determined after stopping, then the vehicle can adjust to current conditions, but the steering angle may not match the desired travel direction
Solution Approach 1:
The system performs preliminary action by storing the steering component information before stopping. This pre-stored accurate steering angle information is retrieved after stopping, ensuring that the steering angle accurately reflects the desired travel direction without requiring re-determination that might introduce errors.
3Measurement precision
If no steering information is stored during stops, then the system remains simple, but the vehicle cannot maintain precise steering control
Solution Approach 1:
The system performs preliminary action by storing steering component information in the storage unit before the vehicle stops. This simple storage mechanism ensures that precise steering angle information is preserved and can be retrieved when the vehicle resumes travel, maintaining steering precision without requiring complex control systems.

AI summary
A vehicle control apparatus includes a generation unit configured to generate a locus of a position of an own vehicle for each predetermined time in a future as a trajectory of the own vehicle, a traveling control unit configured to control a traveling of the own vehicle on the basis of the trajectory generated by the generation unit, and a storage control unit configured to cause a storage unit to store information indicating a steering component corresponding to a trajectory previously generated by the generation unit when the own vehicle is stopped.
