Abstract
An active suspension system senses roadway defects and adjusts an active and controllable suspension system of the vehicle before tires come in contact with the defect. The active suspension system identifies a type of defect or debris, e.g., pothole, bump, object, etc., along with the size, width, depth, and/or height information of the defect to more accurately control operation of the suspension system to prepare for, or avoid contact with the roadway defects and obstacles. Imaging techniques are employed to identify the defect or debris. Operation of a serviced cruise control system is controlled to enhance passenger safety and comfort.
Claims1
An active suspension system comprising:
- a plurality of transmitters mounted on a vehicle, each transmitter corresponding to a respective tire upon which the vehicle travels, the plurality of transmitters configured to send source signals toward the roadway;
- a plurality of receivers mounted on the vehicle, each receiver corresponding to a respective tire upon which the vehicle travels, the plurality of receivers configured to receive reflection signals from the roadway;
- processing circuitry, communicatively coupled to the plurality of receivers, that is configured to analyze the reflection signals to identify at least one roadway defect;
- and
- the processing circuitry is further configured to respond to the identification of the at least one roadway defect by interacting with a first adjustable suspension device before a single front tire encounters the at least one roadway defect and with a second adjustable suspension before a single rear tire encounters the at least one roadway defect.
