A control apparatus for a vehicle includes a RAM adapted to require a power to store and retain data. A nonvolatile memory is provided to be adapted not to require a power to store and retain data. Additionally, a CPU is provided to be adapted to make watch and/or control of an engine and/or an automatic transmission based on the data stored in the RAM. In this control apparatus, the CPU includes a park range position selection judging device for making a decision that the park range position is selected by an operator, and a data storing device for causing the data stored in the RAM to be stored in the nonvolatile memory, based on the decision that the park range position is selected.
