20080256522 | Automobile Controller, Software Generation Method and Software Generation System Thereof - In a processing description part | 10-16-2008 |
20090022255 | Communication System, Real-Time Control Device, and Information Processing System - In addition to fast on-off timing, instructive information on an output wave such as an amplitude or a slope is transmitted through a small number of signal lines. Output wave modifier information such as the amplitude or slope is transferred through serial communication | 01-22-2009 |
20090248181 | Electronic Controller for Power Converter and Motor Drive Circuit - The electronic controller fetches an external signal and performs an input process such as A-D conversion. Upon receipt of processing results for executing operations according to a predetermined program, an output process is performed for sending a signal to the outside board on operation results, a timer outputs at least two of an input process start signal for starting the input process, an output process start signal for starting the output process, and an operation start signal for starting the operation. | 10-01-2009 |
20100030421 | VEHICLE CONTROL SYSTEM - A vehicle control system which can ensure high reliability, real-time processing, and expandability with a simplified ECU configuration and a low cost by backing up an error through coordination in the entire system without increasing a degree of redundancy of individual controllers beyond the least necessary level. The vehicle control system comprises a sensor controller for taking in sensor signals indicating a status variable of a vehicle and an operation amount applied from a driver, a command controller for generating a control target value based on the sensor signals taken in by the sensor controller, and an actuator controller for receiving the control target value from the command controller and operating an actuator to control the vehicle, those three controller being interconnected via a network. The actuator controller includes a control target value generating unit for generating a control target value based on the sensor signals taken in by the sensor controller and received by the actuator controller via the network when the control target value generated by the command controller is abnormal, and controls the actuator in accordance with the control target value generated by the control target value generating unit. | 02-04-2010 |
20110228796 | Real Time Control Network System - Provided is an on-vehicle network which can improve the network use efficiency and reduce the controller processor overhead even when the same communication cycle as the frame cannot be set in the filtering condition of a communication control device. A reference signal transmission controller is arranged in a network so as to generate and transmit a reference signal in accordance with the communication cycle. A reference signal reception controller receives the reference signal and compares the reference signals to a predetermined filtering condition table. If the signal is matched with the table, the controller executes a data reception process and a data transmission process. | 09-22-2011 |
20120224591 | Vehicle-Mounted Network Device - In order to correctly execute a control task in a FlexRay-based vehicle-mounted network system, data synchronization must be guaranteed by completing transmission/reception of all data within a communication cycle. The control task is called in synchronization with a communication cycle. Frames within a communication cycle are partitioned into a first-half slot group and a second-half slot group, each of which is a set of consecutive frames. During the slots of the first-half slot group, a data transmission/reception unit writes transmission frames of the second-half slot group and reads the reception frames of the second-half slot group. During the slots of the second-half slot group, the transmission/reception unit writes the transmission frames, and reads the reception frames, of the first-half slot group. | 09-06-2012 |
