Abstract
A method is provided for generating a vehicle lateral acceleration signal for use in an active tilt control system in a vehicle having a sprung mass center of gravity. A single lateral accelerometer is mounted at the sprung mass center of gravity of the vehicle to generate a first lateral acceleration signal (acg). A second lateral acceleration signal (aLapprox) is generated representative of a vehicle lateral acceleration at a point spaced from the sprung mass center of gravity based upon the first lateral acceleration signal for use in the active tilt control system.
Claims7
A method of generating a vehicle lateral acceleration signal for use in an active tilt control system in a vehicle having a sprung mass center of gravity, the method comprising:
- monitoring vehicle speed;
- mounting a single lateral accelerometer at the sprung mass center of gravity of the vehicle to generate a first lateral acceleration signal (acg);
- and
- generating a second lateral acceleration signal (aLapprox) representative of a vehicle lateral acceleration at a point spaced from the sprung mass center of gravity based upon said first lateral acceleration signal (acg) and said monitored vehicle speed for use in the active tilt control system.
A method of generating a vehicle lateral acceleration signal for use in an active tilt control system in a vehicle having a sprung mass center of gravity, the method comprising:
- monitoring vehicle speed;
- mounting a single lateral accelerometer to the vehicle at a specific mounting point to generate a first lateral acceleration signal;
- and
- generating a virtual second lateral acceleration signal (aLapprox) representative of vehicle lateral acceleration at a point spaced from the sprung mass center of gravity based upon said first lateral acceleration signal and based on said monitored vehicle speed for use in the active tilt control system, said point spaced from the sprung mass center of gravity not having an accelerometer.
