Patent ID: 7778743

Claim:
A vehicular remote control device configured for controlling transmission of a request signal when the request signal is transmitted to a portable unit from a transmitting unit of a vehicle-mounted device, based on a trigger signal input from a predetermined switch of a vehicle operated by an operator, comprising: a counting unit configured for increasing a counted value at predetermined regular time intervals during a transmission time of said request signal in response to inputting of said trigger signal, while decreasing said counted value at said predetermined regular time intervals during a non-transmission time of said request signal; and a transmission control unit configured for controlling permission and prohibition of transmission of said request signal based on comparison of said counted value with a predetermined threshold value, wherein said threshold value comprises a first threshold value and a second threshold value that is lower than said first threshold value, and wherein said control unit is configured to prohibit transmission of said request signal when said counted value exceeds said first threshold value, and permits transmission of said request signal when said counted value falls to the second threshold value or lower.
