Abstract

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.

Claims

1. A control apparatus for a vehicle, comprising:

a RAM adapted to require a power to store and retain data;

a nonvolatile memory adapted not to require a power to store and retain data; and

a CPU adapted to make at least one of watch and control of at least one of an engine and an automatic transmission based on the data stored in the RAM,

wherein 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.

2. A control apparatus as claimed in claim 1, wherein the park range position selection judging device makes the decision that the parking range position is selected, based on input of a signal from an inhibitor switch.

3. A control apparatus as claimed in claim 1, wherein the CPU is electrically connected to the RAM and the nonvolatile memory.
