Title:
VEHICLE CONTROLLER
Document Type and Number:
Japanese Patent JP2022177547
Kind Code:
A
Abstract:
To provide a vehicle controller capable of making flexible resonance determination adapted to various conditions as compared to a controller making determination on the basis of a rule-based determination condition.SOLUTION: A system control unit 100 as a vehicle controller is mounted on a hybrid vehicle 10 and controls the hybrid vehicle 10. The system control unit 100 comprises a storage unit 120 in which there is stored data on a learned model obtained by training, through supervised learning, a neural network for outputting the probability of occurrence of resonance on the basis of input data including time-series data on wheel speed index values and time-series data on detection values of a G sensor 131. The system control unit 100 comprises a processing circuit 110 which, when determining that the resonance occurs on the basis of the probability output by inputting the input data into the learned model, executes avoidance processing of reducing torque generated by a power train before the action of an excessive load due to the resonance.SELECTED DRAWING: Figure 1
