Abstract: An electronic control device for a vehicle according to the present invention includes an action prediction unit that predicts the action of an object around the vehicle on the basis of external information acquired from external information detection units that detect external information of the vehicle, and a determination unit for a detection unit that determines whether an abnormality has occurred in the external information detection unit by comparing external information acquired from the external information detection unit at the time corresponding to a prediction result of the action prediction unit to the prediction result of the action prediction unit.

Abstract: An object of the present invention is to enhance the reliability of an autonomous driving system. The autonomous driving system includes: a higher-level control device 1 that outputs a control target value of an actuator group based on an action plan of a vehicle; and a lower-level control device 2 that controls the actuator group of the vehicle based on a command from the higher-level control device 1. The lower-level control device 2 holds the control target value of the vehicle provided by the higher-level control device 1 over a specific period. When the higher-level control device 1 does not satisfy a desired function, the lower-level control device 2 is configured to be controlled based on the held control target value. The action plan is followed by determining and correcting a difference between an actual action value and the control target value of the vehicle.

Abstract: There is achieved an electronic control device capable of calculating an optimal travel plan even during dynamic reconfiguration of a calculation circuit configuration. When a driving state changes, a travel plan parameter generation/selection unit divides evaluation calculation units into two blocks and performs reconfiguration of the respective evaluation calculation units a plurality of times via a reconfiguration control unit. While the evaluation calculation units are reconfigured, the evaluation calculation units performs evaluation calculation, and while the evaluation calculation units are reconfigured, the evaluation calculation units perform evaluation calculation. Thus, even while some of the evaluation calculation units are being reconfigured, it is possible to continue evaluation of the travel plan in the rest of the evaluation calculation units.

Abstract: The present invention addresses the problem of implementing a neural network using a small-scale circuit by simplifying the multiplication of the input data by weight data. The neural network circuit according to the present invention is configured from: a means for multiplying input data by a rounded value of the mantissa part of weight data; a means for shifting the multiplication result by the number of bits of the rounded value; a means for adding the shifted result to the original input data; and a means for shifting the addition result by the number of bits of the exponent part of the weight.

Abstract: Provided is a method of detecting and preventing soft errors without performing multiplexing. As a result, it is possible to improve reliability of a device while suppressing an increase in mounting cost and reduction in operation speed accompanied with it. A diagnosis system includes an initial parameter generation unit which generates a plurality of initial parameters predicted on the basis of an external input; an operation unit which has a plurality of operators operating optimal solutions to the initial parameters by using an evaluation function describing a control object; and a diagnosis unit which diagnoses the operation unit on the basis of an output of the operation unit. When an optimal solution candidate giving an evaluation value deviating from a value taken by each evaluation value by a constant threshold or more among evaluation values corresponding to the optimal solutions to the initial parameters is found, the diagnosis unit diagnoses an error of the operation unit.

Abstract: The objective of the present invention is to increase reliability in an electronic control device when speculative execution is performed, by reducing the risk of erroneous control by the electronic control device, said erroneous control being due to speculative execution failures (such as failures to predict a future state or failure to complete a control calculation due to the execution of an advanced control calculation) which are generated when speculative execution is performed using limited hardware resources in an electronic control device having a control period restriction. Therefore, this electronic control device, which performs a calculation in accordance with one or more external inputs, and outputs a calculation result by a prescribed time, has one or more first calculation units that perform a calculation using a current input, and one or more second calculation units that perform a calculation using a prior input that been input at a point in time prior to the current input.
