  • Patent number: 11746718
    Abstract: A control device includes a controller configured to: obtain a driving condition and an actual value of a controlled amount of an engine; use a transformed engine model to calculate an estimate value of a future controlled amount, from the obtained driving condition and a candidate value of an operation amount for controlling the controlled amount, the transformed engine model in which an activation function of each neuron is transformed using a linear inequality function having a binary variable, the transformed engine model for which a weight coefficient, bias, and upper and lower limits of an input/output variable of the each neuron are set based on an engine model that has a multilayer neural structure and the activation function of a ReLU structure, receives the driving condition and operation amount as input, and predicts dynamic characteristics of the engine; determine a value of the operation amount, based on error between the calculated estimate value and a target value of the controlled amount ident

  • Publication number: 20230138137
    Abstract: A control device calculates a first estimate value of a first monitored amount of a mobile object, from sensor information of a controlled object, using a transformed first model obtained by transformation of a first model having a multi-layered neural structure and activation functions of a ReLU structure, and predicting dynamic behavior of the mobile object. The transformed first model is a model for which weight coefficients, biases, and upper and lower limit values of input/output variables of neurons are set based on the first model and in which activation functions of the neurons are transformed using a linear inequality function having a binary variable. The control device calculates a second estimate value of a second monitored amount of the controlled object from a candidate value of an operation amount for controlling the second monitored amount.

  • Publication number: 20150307100
    Abstract: The present invention provides a vehicle controller that predicts the behavior of the host vehicle and the preceding vehicle in accordance with the input road shape by use of the mass models of the host vehicle and the preceding vehicle before determining the acceleration of the host vehicle based on the result of the driver model and behavioral prediction. The unintended acceleration of the driver and the two-step deceleration can be thereby less frequent. And the algorithm the vehicle controller possesses alleviates the sense of discomfort felt by the driver. The vehicle controller further enables the cruise control in keeping with the intended driving operation of the driver while the security is ensured even when both the adaptive cruise control (ACC) and the deceleration control ahead of curve are to be performed simultaneously.
