Abstract
A vehicle integrated control method includes determining a road surface status, determining a vehicle status, determining an integrated control mode by determining a control status of an electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status, and controlling the electronic control suspension and an in-wheel system by determining a control amount based on the determined integrated control mode.
Claims20
A vehicle integrated control method, the method comprising:
- determining a road surface status;
- determining a vehicle status;
- determining an integrated control mode by determining a control status of an electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status;
- and
- controlling the electronic control suspension and an in-wheel system by determining a control amount based on the determined integrated control mode.
A vehicle integrated control system for improving a riding quality using an electronic control suspension and an in-wheel system, the vehicle integrated control system comprising:
- a road surface status determination module configured to determine a road surface status;
- a vehicle status determination module configured to determine a vehicle status;
- an integrated control mode determination module configured to determine an integrated control mode by determining a control status of the electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status;
- a control amount determination module configured to determine a control amount based on the determined integrated control mode;
- a first control module configured to control the electronic control suspension based on the determined control amount;
- and
- a second control module configured to control the in-wheel system based on the determined control amount.
The vehicle integrated control system of claim ii, wherein the vehicle status determination module is configured to determine the vehicle status when the road surface status is an irregular road surface including a bump or a pothole.
The vehicle integrated control system of claim ii, wherein the vehicle status determination module is configured to:
- determine whether a turning characteristic and a straightness are within a predetermined allowable range;
- and
- determine the control status of the electronic control suspension and the motion of the sprung mass and the unsprung mass when the turning characteristic and the straightness are within the predetermined allowable range.
The vehicle integrated control system of claim ii, wherein the road surface status determination module is configured to determine the road surface status using a G-value level and a vibration frequency based on sensing values measured by a vehicle body gravity sensor and a wheel gravity sensor.
