Abstract

The vehicle control system of the present disclosure includes a meter-side control device that is installed in a vehicle and can measure the total distance traveled by the vehicle, and a backup device that can obtain a copy of the total distance measured by the meter-side control device. Data communication between the meter-side control device and the backup device uses an authentication signal using a common key, and a new communication between the meter-side control device and the backup device When registering a common key, the larger value of the total mileage value stored in the meter side control device and the total mileage value stored in the backup device is sent to the meter side control device. Total mileage.

Claims12

Dependent claims

A vehicle control system comprising:

a meter-side control device that is installed in a vehicle and comprises a total travel distance measurement unit configured to measure and store a total travel distance of the vehicle;
a backup device comprising a backup unit, that is configured to acquire and store a copy of the total travel distance measured by the meter-side control device;
and
a total travel distance inheritance unit, wherein:
in data communication between the meter-side control device and the backup device, an authentication signal using a common key is used;
and
when a new common key is registered between the meter-side control device and the backup device, the total travel distance inheritance unit specifies a larger value of a value of the total travel distance stored in the total travel distance measurement unit or a value of the copy of the total travel distance stored in the backup unit, to be the total travel distance of the total travel distance measurement unit.

4 more elements

A vehicle control system comprising:

a first meter-side control device that is installed in a vehicle and comprises a total travel distance measurement unit configured to measure and store a total travel distance of the vehicle;
a backup device comprising a backup unit, that is configured to acquire and store a copy of the total travel distance measured by the first meter-side control device;
and
a total travel distance inheritance unit that is configured to transfer the total travel distance from the first meter-side control device to a second meter-side control device, wherein:
in data communication between the first meter-side control device and the backup device, an authentication signal using a common key is used;
and
when a new common key is registered between the second meter-side control device and the backup device, the total travel distance inheritance unit specifies a larger value of a value of the total travel distance stored in the second meter-side control device or a value of the copy of the total travel distance stored in the backup unit and stores the specified value to the second meter-side control device as a total travel distance of the second meter-side control device.

A vehicle control system comprising:

a meter-side control device that is installed in a vehicle and that is configured to measure and store a total travel distance of the vehicle;
and
a backup device that is configured to acquire and store a copy of the total travel distance measured by the meter-side control device, wherein:
in data communication between the meter-side control device and the backup device, an authentication signal using a common key is used;
when a new common key is registered between the meter-side control device and the backup device, a larger value of a value of the total travel distance stored in the meter-side control device and a value of the total travel distance stored in the backup device is taken as the total travel distance of the meter-side control device;
and
registration of the new common key is limited to one time.
