Abstract

The invention relates to a controller for a vehicle, wherein, the operation of the vehicle is controlled by one of the two counting controllers, which are connected by a communicator, on the basis of a target control quality figured out by the other counting controller. If any abnormality occurs in the communicator, in order to deal with the abnormality as soon as possible, one counting controller figures out a target controlling quantity and compares the quantity with the quality received from the other device; or a third counting controller compares the target controlling quantity directly transmitted by the other counting controller with the target controlling quality transmitted from the other counting controller through the communicator and one counting controller, and makes judgment on the abnormality through the difference among the target controlling quantities to change the operation control.

Description

technical field [0001] The present invention relates to a control device for a vehicle, which includes two calculation control devices connected via a communication device, and is adapted to be calculated by one calculation control device based on the vehicle state quantity calculated by the other calculation control device and input to the computer via the communication device. The one calculates the target control amount of the control device to control the operation of the vehicle. Background technique [0002] When signals are transferred between two calculation control devices, in addition to calculation errors in the calculation control devices, communication errors may also occur due to fixation of the RAM of the communication buffer and the like. Regarding this problem, Japanese Unexamined Patent Publication No. 6-298105 describes constructing a vehicle operation control device such that two calculation control devices not only monitor each other's calculation result...
