Abstract
A method of electronically controlling operation of a vehicle is disclosed here. The vehicle has two engines, and the disclosed method involves: obtaining respective tachometer data from the two engines; obtaining vibration data from vibration sensors associated with the two engines; calculating a vibration phase angle between the two engines, the vibration phase angle calculated from the tachometer data from the engines and from the vibration data for the engines; and controlling operation of one or both of the engines, in response to the calculated vibration phase angle.

A method of electronically controlling operation of a vehicle having a first engine and a second engine that cooperate to provide propulsion for the vehicle, the method comprising:
- obtaining first tachometer data from a first tachometer associated with the first engine;
- obtaining second tachometer data from a second tachometer associated with the second engine;
- obtaining first vibration data from a first vibration sensor associated with the first engine;
- obtaining second vibration data from a second vibration sensor associated with the second engine;
- calculating a vibration phase angle between the first engine and the second engine, the vibration phase angle calculated from the first tachometer data, the second tachometer data, the first vibration data, and the second vibration data;
- and
- controlling operation of the first engine and/or the second engine, in response to the calculated vibration phase angle.
A system onboard a vehicle having a first engine and a second engine that cooperate to provide propulsion for the vehicle, the system comprising:
- at least one processor;
- and
- at least one processor-readable medium associated with the at least one processor, the at least one processor-readable medium storing processor-executable instructions configurable to be executed by the at least one processor to perform a method of controlling operation of the vehicle, the method comprising:
- obtaining first tachometer data from a first tachometer associated with the first engine;
- obtaining second tachometer data from a second tachometer associated with the second engine;
- obtaining first vibration data from a first vibration sensor associated with the first engine;
- obtaining second vibration data from a second vibration sensor associated with the second engine;
- calculating a vibration phase angle between the first engine and the second engine, the vibration phase angle calculated from the first tachometer data, the second tachometer data, the first vibration data, and the second vibration data;
- and
- controlling operation of the first engine and/or the second engine, in response to the calculated vibration phase angle.
A vehicle comprising:
- a first engine;
- a second engine;
- a first tachometer associated with the first engine;
- a second tachometer associated with the second engine;
- a first vibration sensor associated with the first engine;
- a second vibration sensor associated with the second engine;
- a computer-based system having at least one processor;
- and
- at least one processor-readable medium associated with the at least one processor, the at least one processor-readable medium storing processor-executable instructions configurable to be executed by the at least one processor to perform a method of controlling operation of the vehicle, the method comprising:
- obtaining first tachometer data from the first tachometer;
- obtaining second tachometer data from the second tachometer;
- obtaining first vibration data from the first vibration sensor;
- obtaining second vibration data from the second vibration sensor;
- calculating a vibration phase angle between the first engine and the second engine, the vibration phase angle calculated from the first tachometer data, the second tachometer data, the first vibration data, and the second vibration data;
