Remote control device for an activation device mounted in a vehicle
In a remote control device for a vehicle including: a portable transmitter configured to repeatedly transmit a signal for giving an instruction to activate an activation device mounted in a vehicle, in response to an operation of a manipulator which is performed continuously for a predetermined time or more; and a vehicle-side receiver provided in the vehicle to activate the activation device based on the signal transmitted from the portable transmitter, the portable transmitter transmits a first signal including a data frame having at least an ID code, a function code determining an action of the activation device, and a first error detection code and then repeatedly transmits a second signal, and a data frame of the second signal having the same function code as that of the first signal and a second error detection code generated based on the function code and the data frame of the first signal.
1. A remote control device for a vehicle comprising:
a portable transmitter configured to repeatedly transmit a signal for giving an instruction to activate an activation device mounted in a vehicle, in response to an operation of a manipulator which is performed continuously for a predetermined time or more; and
a vehicle-side receiver provided in the vehicle to activate the activation device on the basis of the signal transmitted from the portable transmitter, wherein
in response to the continuous operation of the manipulator which is performed to give the instruction to activate the activation device, the portable transmitter transmits a first signal including a data frame having at least an ID code, a function code determining an action of the activation device, and a first error detection code and then repeatedly transmits a second signal, and
a data frame of the second signal is set to have only the same function code as the function code of the first signal and a second error detection code generated based on said function code and the data frame of the first signal.
2. The remote control device for a vehicle according to claim 1 , wherein
the data frame of the first signal has a rolling code, the ID code, the function code, an encryption code, and the first error detection code generated from the rolling code, the ID code, the function code, and the encryption code, and
the portable transmitter generates the second error detection code, included in the data frame of the second signal, from the function code and the ID code in the data frame of the first signal.
3. The remote control device for a vehicle according to claim 1 , wherein the portable transmitter is capable of transmitting a signal for giving an instruction to unlock or lock a door, in response to an operation of the manipulator which is performed for a short time, less than the predetermined time.
4. The remote control device for a vehicle according to claim 2 , wherein the portable transmitter is capable of transmitting a signal for giving an instruction to unlock or lock a door, in response to an operation of the manipulator which is performed for a short time, less than the predetermined time.
