On-vehicle controller
A module driver or a master obtains the load IDs of the respective first loads connected to the downstream side of the module driver, recognizes the classification of areas, such as door, roof and floor areas, or a module according to the obtained load IDs, and allocates an appropriate driver ID to the module driver in each area. Each first load has a load ID. The load IDs are allocated to the respective second loads on the downstream side of the module driver on the basis of the allocated driver ID. The area or the module is recognized on the basis of the combination of the load IDs of the plurality of first loads, whereby malfunctions caused by erroneous assembling of the first loads are suppressed.
1. An on-vehicle controller, comprising:
module drivers capable of being disposed in any one of a plurality of areas on a vehicle to control first loads having their own load IDs; and
a power distribution section configured so as to be able to communicate with the module drivers and so as to store module driver IDs allocated to the plurality of areas while being associated with the respective load IDs, wherein
each of the module drivers has a function of obtaining the load ID from each of the first loads in a respective one of the areas and transmitting the load ID to the power distribution section,
the power distribution section has a function of transmitting the module driver ID to each of the module drivers on the basis of the load ID received, and
each of the module drivers has a function of obtaining its own module driver ID.
2. The on-vehicle controller set forth in claim 1 , wherein
a respective one of the module drivers and a plurality of the first loads to be controlled by the respective one of the module drivers are disposed in each of the plurality of areas,
the information to be transmitted from each of the module drivers to the power distribution section includes the plurality of load IDs obtained from at least the plurality of the first loads, and
the power distribution section determines the module driver ID on the basis of the plurality of load IDs.
3. An on-vehicle controller, comprising:
module drivers capable of being disposed in any one of a plurality of areas on a vehicle to control a plurality of first loads having their own load IDs; and
a power distribution section configured so as to be able to communicate with the module drivers and so as to store module driver IDs allocated to the plurality of areas while being associated with the respective load IDs, wherein
the power distribution section has a function of obtaining the respective load IDs from the plurality of first loads to be controlled by the respective module drivers via the respective module drivers and also has a function of transmitting the module driver IDs determined on the basis of the obtained respective load IDs to the respective module drivers, and
the respective module drivers have a function of obtaining their own module driver IDs.
