Control system for adjustable suspension based on route and road type
A recently filed patent (Publication Number: US20230311606A1) describes a control system for an adjustable suspension of a vehicle. The control system is designed to operate in at least two different configurations and includes one or more controllers. These controllers receive route data and map data, which provide information about the expected route and road type for a specific road section. Based on this information, the control system outputs a switch signal to instruct the adjustable suspension to switch between the two different configurations before the vehicle reaches the road section.
The two different configurations of the adjustable suspension include a first configuration for driving on rougher road surfaces and a second configuration for reduced drag on smoother road surfaces. The control system is also capable of estimating a stable stretch and outputting the switch signal based on this estimation. Additionally, the control system can estimate the energy gain resulting from switching between the two different configurations and instruct the suspension to switch based on this estimated energy gain.
To make informed decisions about switching configurations, the control system can receive various inputs such as the expected driving speed, traffic information, weather information, planned route from a navigation system, historic travel data relating to the vehicle, and historic travel data relating to the user of the vehicle. The control system uses these inputs to determine when to switch between configurations.
The patent also describes an adjustable suspension system for a vehicle that incorporates the control system described in the claims. Furthermore, a vehicle is mentioned that includes this adjustable suspension system.
In terms of controlling the adjustable suspension, the patent outlines a method that involves receiving route data and map data, similar to the control system. The method then outputs a switch signal to instruct the adjustable suspension to switch between configurations based on the expected route and road type information.
Overall, this patent presents a control system, adjustable suspension system, and method for optimizing the performance of a vehicle's suspension based on the expected route and road conditions. By switching between different configurations, the vehicle can adapt to different road surfaces and reduce drag on smoother roads, potentially improving comfort and fuel efficiency.
