摘要： PROBLEM TO BE SOLVED: To provide a distributed processing type controller which is simple in system constitution, light in the load on the communication work of each controller, actualized by a small-scale circuit, and easily changed in specifications. SOLUTION: A repeating controller 1 uses the 1st protocol for a communication with an external tool 7 through the 1st communication channel 8 and uses the 2nd protocol for a communication with subcontrollers 2 and 3 through the 2nd communication channel 9, thus repeats a communication between the external tool 7 and subcontrollers 2 and 3 through those operations. Further, the repeating controller 1 has a writable nonvolatile memory 111 having respective partitioned storage areas for the subcontrollers 2 and 3 and performs nonvolatile memory access for the subcontrollers 2 and 3 by transmitting the stored data in a corresponding storage area to the subcontrollers 2 and 3 through the 2nd communication channel 9 in response to read access to the storage area by the subcontrollers 2 and 3 and also writing data to be written received through the 2nd communication path 9 in a corresponding storage area in response to write access to the storage area by the subcontrollers 2 and 3.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle door unlock system capable of storing information indicating a vehicle collision inside the system in the shortest time and surely executing door lock release corresponding to the vehicle collision without providing an exclusive storage area or an exclusive power supply holding circuit.SOLUTION: A data storage part (nonvolatile memory or the like) shared and used by various control systems loaded on a vehicle is utilized. When a vehicle collision is detected (S108:Yes), new data writing to the data storage part is inhibited (S109). Also, whether or not there is data writing during processing when it is inhibited is determined (S110). When there is the data writing during processing, an error is buried in data by the stop of the data writing (S111). When there is no data writing during processing, an error is buried in the data stored in an area where the time to data writing completion is the shortest among the storage areas of the data storage part (S112).

摘要： PROBLEM TO BE SOLVED: To provide multiple communication equipment capable of securing the transmission/reception of data through a communication bus having no relation with a spot, where abnormlaity has been occured, even when the abnormality occurs at the spot at one part of the communication bus. SOLUTION: When any abnormality occurs at a certain spot on a communication bus 22, a control circuit 34 outputs a communication bus disconnect signal to a communication bus disconnecting circuit 38 or 39 and stops transmitting/ receiving data with the communication bus including the abnormal spot between an instrument panel system communication bus 23 and a door system communication bus 24. Thus, the transmission/reception of data can be secured in the system of the communication bus 22 including no abnormal spot and even when any fault occurs in the door system communication bus 24 during a travel, for example, driving can be prevented from being affected with no influence upon a meter 25, EFI 26 and ABS 27 as the measuring/controlling instruments of an instrument panel system.

摘要： PURPOSE: To reduce dark current and to secure a stable operation in the communication circuit of a local area network for mobile object which is driven by a battery. CONSTITUTION: When a microcomputer 3 judges that a pertinent vehicle is in its parking state, the microcomputer turns off the output of the output port PO1. As a result, the power feeding to a comparator 201 and reference voltage generation circuits (resistances 205 and 206) through a power feeding line 200 is stopped. When the potential of a communication bus 1 becomes data reception potential, an interruption is applied to an interruption port INT 1 according to the potential change. The microcomputer 3 turns on the output of the output port PO1 according to this interruption and resumes the power feeding to the comparator 201 and the reference voltage generation circuits through the power feeding line 200. The data to the comparator 201 is inputted via a diode 203 for back flow prevention. A diode 209 composes the temperature compensating circuit.

摘要： PROBLEM TO BE SOLVED: To perform appropriate processing while suppressing the useless consumption of power even when program abnormality occurs in an in-vehicle electronic control device configured such that when program abnormality is determined by memory check, a CPU(microcomputer) is resets by itself.SOLUTION: A CPU periodically performs memory check, and when determining that the storage content of the memory is abnormal, writes abnormality determination frequency (error frequency) in an error frequency storage register 32, and resets the CPU itself. Just after the reset of the CPU, a comparator 34 determines whether or not the error frequency stored in the error frequency storage register 32 is equal to or more than an error determination threshold before first memory check is performed. When the error frequency is equal to or more than the error determination threshold, an activation destination determiner 36 allows the CPU to execute a specific error handling processing program among programs in the memory.

摘要： PROBLEM TO BE SOLVED: To reduce a processing load attended with deciphering of enciphered data in an on-vehicle receiver for receiving/deciphering the enciphered data for using them for controlling on-vehicle equipment. SOLUTION: Inside a RAM, a buffer area is secured for storing enciphered data and deciphered data thereof as a set. When the enciphered data are received, it is decided whether the received enciphered data are stored on the buffer or not and when such data are not stored (S120: NO), these data are deciphered. Then, these deciphered data are validated (S130) and these deciphered data are stored on the buffer together with the enciphered data (S150). When the received enciphered data are stored on the buffer (S120: YES), on the other hand, in place of deciphering of these enciphered data, the deciphered data stored in the buffer are validated (S160). Namely, as long as received enciphered data are matched with the enciphered data stored on the buffer, deciphering is not performed, so that the processing burden of a CPU for performing deciphering can be reduced.

摘要： PROBLEM TO BE SOLVED: To prevent the reception efficiency of radio communication equipment for vehicle from being lowered even under a condition where received data are unstable at the time of detecting the abnormality of the data. SOLUTION: The radio communication equipment is constituted to discriminate whether or not the data from 1st bit to 8th bit of 120-bit data stored in a buffer are identical with the data from 97th bit to 104 bit of the 120-bit data in a step 130 and to detect abnormality of the data in and after a step 140 only when the data are identical. When the data are not identical, the equipment does not destruct all of the 120-bit data, but once comes out of the routine and, thereafter, continuously updates the 120-bit data one bit by one bit by repeating the steps from a step 100 to the step 130 until the data are discriminated as identical in the step 130.
