Abstract

The vehicle control apparatus, which performs vehicle control on a vehicle by issuing commands generated on the basis of results of computations which the vehicle control apparatus performs by use of a plurality of parameters, includes a first section to obtain a vehicle state of the vehicle, and a second section to make, for each of the plurality of the parameters, a determination whether or not the vehicle state has changed in compliance with corresponding at least one of rewrite conditions respectively set for the plurality of the parameters. If the determination is affirmative, the second section rewrites the parameter to a corresponding one of rewrite values respectively assigned to the plurality of the parameters.

Claims

1. A vehicle control apparatus to perform vehicle control on a vehicle by issuing commands generated on the basis of results of computations which the vehicle control apparatus performs by use of a plurality of parameters, comprising:

a first section to obtain a vehicle state of the vehicle; and

a second section to make, for each of the plurality of the parameters, a determination whether or not the vehicle state has changed in compliance with a corresponding at least one of rewrite conditions respectively set for the plurality of the parameters, and if the determination is affirmative, rewrite the parameter to a corresponding one of rewrite values respectively assigned to the plurality of the parameters.

2. The vehicle control apparatus according to claim 1, wherein the vehicle control apparatus is configured to perform data exchange with a plurality of in-vehicle networks, and each of the rewrite conditions are set for each of the plurality of the in-vehicle networks.

3. The vehicle control apparatus according to claim 1, wherein the vehicle control apparatus is connected with a plurality of power sources, the first section is configured to obtain an output voltage state of each of the plurality of the power sources as the vehicle state, and each of the rewrite conditions prescribes a value of the output voltage of a corresponding one of the plurality of the power sources as the rewrite value thereof.

4. The vehicle control apparatus according to claim 1, wherein at least one of the plurality of the parameters is set with two or more of the rewrite conditions associated with different rewrite values.

5. The vehicle control apparatus according to claim 1, wherein each of the first and second sections operates in accordance with a vehicle control program stored in a memory of the vehicle control apparatus.
