System and method of load sharing control for automobile
First Claim
1. A method of load sharing processing operations between a vehicle mounted station and a base station including the steps of said vehicle mounted station detecting operating conditions of the vehicle, transmitting data representative of the detected operating conditions to the base station which do not require real-time processing and are determined to be processed at the base station, said base station receiving said data from the vehicle mounted station, processing said data in accordance with data stored by said base station, said base station transmitting processed data to a receiver at said vehicle mounted station, and control means at said vehicle mounted station connected to the vehicle mounted receiver and performing at least one of revising and displaying the vehicle operating conditions in dependence upon the processed data received.

Abstract
A system and method for load sharing processing operations between a vehicle mounted station (105) and a stationary base station (25) having a large capacity host computer is described. The vehicle mounted station has detectors for determining operating conditions of a vehicle and controllers (3, 4, 501) for varying the operating conditions. The controllers are connected to a transmitter-receiver (5) which is arranged to communicate over a path (10) with a transmitter-receiver (11) of the base station. The base station has a host computer (18) having a large memory capacity. At predetermined intervals, for example, distance of travel or at engine stop, the vehicle transmitter (5) transmits operating conditions to the base receiver (11) for data processing and the base transmitter (11) then transmits processed data back to the vehicle receiver (5), whereupon the controllers (3, 4, 501) modify the vehicle operating conditions. The vehicle operating conditions may be an indication of life expectancy of fuel injectors or sensors, updating data processing maps. The presence of abnormal operating conditions may be detected by the vehicle mounted station, evaluated by the base station and an emergency warning indication provided back to the vehicle mounted station, or if the abnormal condition is not of an emergency nature then counter measures are transmitted from the base station to the vehicle mounted station.
