Title:
ONBOARD COMMUNICATION SYSTEM AND ELECTRONIC DISTANCE METER CONNECTED TO IT
Document Type and Number:
Japanese Patent JP3583278
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an onboard communication system connecting electrical apparatuses including at least a combination meter unit, an antilock brake system unit and a rotation sensor mounted on a vehicle via a data transmission line for data exchange between the electrical apparatuses.
SOLUTION: This onboard communication system 1 connects on-vehicle electrical apparatuses including at least a combination meter unit 11, an antilock brake system unit 15 and a rotation sensor 5 outputting a rotation pulse each time a wheel is rotated by the unit distance via a data transmission line 3 for data exchange between the electrical apparatuses. Each of the electrical apparatuses except for the rotation sensor 5 receives the rotation pulses outputted from the rotation sensor 5 in sequence via the data transmission line 3, applies the prescribed arithmetic process to the received rotation pulses, and applies the arithmetic result for the prescribed purpose.
