<p>PURPOSE:To concurrently summarize units, make high speed of treatment, and reduce cost as a whole system by equipping the communication serial bus lines of communication nodes for first and second groups and data-transfer parallel bus line of the communication node for only the first group. CONSTITUTION:Controller system nodes (EGI node G, ABS/TRC nodes 7 and 4, WS node 8, and ACS node 10) are interconnected with a parallel bus 11. These four controller system nodes are also connected to a serial bus 1. Also such 'body' system nodes are connected to the serial bus 1 as a vehicle-height sensor node 30 for ACS, hydraulic opening/closing valve node 31 for ACS, wheel- speed sensor 32, node 33 for ABS/TRC brake pressure adjusting valve, handle steered-angle sensor 34, rear-wheel steered-angle sensor node 35 for rear-wheel steering control, motor node 37 for 4WS, acceleration sensor node 38 for ACS, and fuel injection valve node 39 etc.</p> |
