PROBLEM TO BE SOLVED: To provide a responsiveness learning device of a pressure sensor capable of improving pressure detection accuracy of the pressure sensor.SOLUTION: While injection is performed by a predetermined cylinder, a combination of a first non-injection cylinder and a second non-injection cylinder is selected. A first non-injection time sensor waveform is detected on the basis of an output of a pressure sensor corresponding to the first non-injection cylinder, and a second non-injection time sensor waveform is detected on the basis of an output of the pressure sensor corresponding to the second non-injection cylinder. Deviation of a response time between the first non-injection time sensor waveform and the second non-injection time sensor waveform is calculated, and, based on the calculated deviation, a learning value relating to responsiveness of the pressure sensor corresponding to the first non-injection cylinder is learned, repeatedly while sequentially changing a combination of the first non-injection cylinder and the second non-injection cylinder. When calculating the deviation, a detection time of the first non-injection time sensor waveform is corrected on the basis of the learning value corresponding to the first non-injection cylinder, and a detection time of the second non-injection time sensor waveform is corrected on the basis of the learning value corresponding to the second non-injection cylinder. |
