Vehicle control apparatus with data reprogrammable via wireless communication network
First Claim
1. A vehicle control apparatus installed in a vehicle for reprogramming data stored therein based on a reprogramming instruction transmitted thereto via a wireless communication network, the vehicle control apparatus comprising:
- an asking unit configured to ask a data reprogramming unit about whether the reprogramming instruction is validated or not, the data reprogramming unit having been authorized to reprogram the data stored in the vehicle control-apparatus, the data programming unit being external to the vehicle control system; and
a determining unit configured to receive a reply to the asking transmitted from the data reprogramming unit via the wireless communication network and to determine whether to enable or disable the reprogramming of the data stored in the vehicle control apparatus based on the received reply.

Abstract
In a vehicle control apparatus for reprogramming data stored therein based on a reprogramming instruction transmitted thereto via a wireless communication network, an asking unit is provided. The asking unit asks a data reprogramming unit about whether the reprogramming instruction is validated or not. The data reprogramming unit has been authorized to reprogram the data stored in the vehicle control apparatus. A determining unit is provided in the vehicle control apparatus. The determining unit receives a reply to the asking transmitted from the data reprogramming unit via the wireless communication network and determines whether to enable or disable the reprogramming of the data stored in the vehicle control apparatus based on the received reply.

10. A vehicle control apparatus for reprogramming data stored therein based on a reprogramming instruction transmitted thereto via a first wireless communication network which may at times be unreliable, the vehicle control apparatus comprising:
-
a receiving unit configured to receive a reprogramming disable instruction transmitted via an alternative second wireless communication network different from the first wireless communication network, thereby increasing a probability that said disable instruction is received even if the first wireless communication network is then in an unreliable status; and a disabling unit configured to disable, according to the reprogramming disabling instruction, any one of; (a) reprogramming of the data stored in the vehicle control apparatus; and (b) receipt of an alternative reprogramming instruction transmitted via the first wireless communication network; use of said alternative second wireless communication network thereby increasing reliability of data reprogramming systems based on the first wireless communication network by suppressing invalid reprogramming even if reliability of the first wireless communication network is not guaranteed or there is a failure in the first wireless communication network. - View Dependent Claims (11, 12, 13)

14. A data reprogramming system for reprogramming data stored in a vehicle control apparatus installed in a vehicle based on a reprogramming instruction transmitted thereto via a wireless communication network, the data reprogramming system comprising:
-
a data reprogramming unit that has been authorized to reprogram the data stored in the vehicle control apparatus, the data reprogramming unit being external to the vehicle control apparatus; an asking unit installed in the vehicle control apparatus and configured to ask the data reprogramming unit about whether the reprogramming instruction is validated or not; and a determining unit installed in the vehicle control apparatus and configured to receive a reply to the asking transmitted from the data reprogramming unit via the wireless communication network and to determine whether to enable or disable the reprogramming of the data stored in the vehicle control apparatus based on the received reply. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A data reprogramming system for reprogramming data stored in a vehicle control apparatus based on a reprogramming instruction transmitted thereto via a first wireless communication network which may at times be unreliable, the data reprogramming system comprising:
-
a data reprogramming unit that has been authorized to reprogram the data stored in the vehicle control apparatus; and a receiving unit installed in the vehicle control apparatus and configured to receive a reprogramming disable instruction transmitted from the data reprogramming unit via an alternative wireless communication network different than the first wireless communication network, thereby increasing a probability that said disable instruction is received even if the first wireless communication network is then in an unreliable status; the reprogramming disable instruction representing disabling of any one of; reprogramming of the data stored in the vehicle control apparatus; and receipt of an alternative reprogramming instruction transmitted via the wireless communication network; use of said alternative second wireless communication network thereby increasing reliability of data reprogramming systems based on the first wireless communication network by suppressing invalid reprogramming even if reliability of the first wireless communication network is not guaranteed or there is a failure in the first wireless communication network. - View Dependent Claims (26, 27, 28, 29)
