摘要： 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 (18) is described. The vehicle mounted station (105) has detectors for determining operating conditions of a vehicle and controllers (3,4,501) for varying the operating conditions. The controllers (3,4,501) 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 (25). The base station (25) 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 receiver vehicle (5), whereupon the controllers (3, 4, 501) modify the vehicle operating conditons. 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 (105), evaluated by the base station (25) and an emergency warning indication provided back to the vehicle mounted station (105), or if the abnormal condition is not of an emergency nature then counter measures are transmitted from the base station (25) to the vehicle mounted station (105).

摘要： An electronic control apparatus for use in an automobile has a base (14) of a good thermal conductivity having one side disposed in contact with engine cooling water. Semiconductor devices (8, 9, 10, 22, 90) are disposed on the other side of the base so that the semi­conductor devices are maintained at the temperature of the engine cooling water, whereby the influence of high ambient air temperature to the semiconductor devices is reduced.
