Abstract
A vehicle controller includes a plurality of detectors, a control unit, a data collecting unit, a serial communication line, and a transmission order setting unit. Data that changes at a speed that is lower than a given speed value is transmitted in a period in which a communication volume is lower than a given communication volume value. The transmission order is an order in which the pieces of detection data are serially transmitted from the data collecting unit to the control unit.
Claims11
A vehicle controller comprising:
- a plurality of detectors that detect a plurality of operation conditions of a power generator;
- a control unit that controls the power generator, based on pieces of detection data outputted from the plurality of detectors;
- a data collecting unit that collects the pieces of detection data together;
- a serial communication line for serially transmitting the pieces of detection data from the data collecting unit to the control unit;
- and
- a transmission order setting unit that sets a transmission order of the pieces of detection data in advance, wherein
- data that changes at a speed that is lower than a given speed value is transmitted in a period in which a communication volume is lower than a given communication volume value, and
- the transmission order is an order in which the pieces of detection data are serially transmitted from the data collecting unit to the control unit.
