VEHICLE CONTROL SYSTEM
First Claim
1. A vehicle control system comprising a vehicle fitted with a device control unit for controlling an onboard device and an interface unit connected to the device control unit, and an external control unit that is configured to access the device control unit via the interface unit,wherein the external control unit comprises an external verification code generating means for generating a code for accessing the device control unit, an external control signal generating means for generating an external control signal for controlling the onboard device and an external communication means for transmitting the external verification code and the external control signal to the interface unit;
- wherein the vehicle comprises an internal verification code generating means for generating an internal verification code for allowing access to the onboard device via the interface unit and an access permitting means for comparing the external verification code with the internal verification code and permitting control of the device control unit by the external control signal when there is a good match; and
wherein the device control unit is provided with a first control mode for having the corresponding device to be controlled by the external control signal when the access permitting means has permitted the device control unit to be controlled with the external control signal when the vehicle is traveling, and a second control mode for having the corresponding device to be controlled according to a default control mode.

Abstract
The control property of an onboard device is changeable by using an external control unit, and the data from the external control unit is authenticated. An onboard gateway unit is provided with a verification code generator for generating a security key, and an external control unit is provided with an application control unit for generating a security key. When the external control unit is connected, a main control logic unit of the gateway unit compares the two keys, and when the keys are verified, the control by the external control unit using an application program is enabled. The onboard device control unit can be easily connected to the external control unit. As the control of the device control unit by an external control signal is enabled only when verified, an unauthorized access can be prohibited, and the onboard deice can be controlled only by an authorized control signal.

12. A vehicle control system comprising a vehicle fitted with a device control unit for controlling an onboard device and an interface unit connected to the device control unit, and an external control unit that is configured to access the device control unit via the interface unit,
wherein the external control unit comprises an external control signal generating means for generating an external control signal for controlling the onboard device and an external communication means for transmitting the external control signal to the interface unit, and wherein the system further comprises a load condition determining means for determining a load condition of the external control unit, and an access limiting means for limiting a control of the onboard device by the external control signal when the load condition determining means has determined a large load for the external control unit.
