摘要:
A vehicular control system which includes a user parameter input module, an external parameter input module, a plurality of objective functions, a policy setting module, and a policy node. The user parameter input module Inputs a user parameter. The external parameter input module inputs an external parameter resulting from an outside environment. The objective functions are set for each control characteristic, respectively, so as to calculate an internal parameter of each control target from the user parameter and the external parameter. The policy setting module sets policies indicating a control index of the user for the objective functions respectively. The policy node weights the objective functions on the basis of the policies, adjusts the internal parameter in accordance with the policy so that the internal parameter is optimized among the objective functions, and issues a command to a control node corresponding to the internal parameter.

An exhaust gas diagnosis system and a vehicle control system for automotive vehicles to reduce the communication lines and the power lines connected to the antiweatherability-required exhaust gas sensor arranged on the exterior of the vehicle are disclosed. The exhaust gas diagnosis system is configured of an engine control unit (electronic control unit), radio terminal units having the sensor function to detect the exhaust gas, and a radio communication repeater to conduct communication and share a part of the process executed by the conventional engine control unit. The communication lines between the sensor and the electronic control unit and the power lines to the sensor required in the conventional systems are eliminated while at the same time reducing the load on the electronic control unit.

A data communication system includes a master device, a plurality of slave devices, at least either a data transmission bus which connects the master device to a plurality of slave devices to transfer data from the master device to the slave devices in synchronism with a synchronous clock signal or a data reception bus over which the master device receives data from the slave devices in synchronism with a synchronous clock signal, and Chip Select signal lines which one-to-one connect the master device to the slave devices. The data communication system also includes communication drivers for setting a physical protocol of each slave device and a communication manager to arbitrate serial communications between the master device and the slave devices. The communication manager arbitrates serial communications to slave devices by their proper physical protocols. Communication protocols such as baud rates, clock polarities, and clock phases are switched by asserted Chip Select signal lines.
摘要:
To reduce the man-hour required in tuning control parameters, a vehicular control system of this invention comprises a user parameter input module, an external parameter input module, a plurality of objective functions, a policy setting module, and a policy node. The user parameter input module inputs a user parameter corresponding to an operation of a user. The external parameter input module inputs an external parameter resulting from an outside environment. The objective functions are set for each control characteristic respectively so as to calculate an internal parameter of each control target from the user parameter and the external parameter. The policy setting module sets policies indicating a control index of the user for the objective functions respectively. The policy node weights the objective functions on the basis of the policies, adjusts the internal parameter in accordance with the policy so that the internal parameter is optimized (minimized or maximized) among the objective functions, and issues a command to a control node corresponding to the internal parameter.
