<p><P>PROBLEM TO BE SOLVED: To provide a vehicular electronic control system discriminating whether a vehicle is in a speed limit region or not from a vehicle speed sensor, converting only signal necessary for release of speed limiter, and acknowledging ECU that vehicle speed is not more than the limit speed. <P>SOLUTION: The vehicular electronic control system connects an engine control unit and the vehicle speed sensor by LAN cable performing CAN communication. A speed limiter releasing device converting vehicle speed data output by the vehicle speed sensor and sending the same to the engine control unit is installed in the LAN cable connecting the vehicle speed sensor to the engine control unit. The speed limiter releasing device is provided with a function sending converted vehicle speed data lower than predetermined limit speed to the engine control unit when vehicle speed data on CAN communication output by the vehicle speed sensor is in a speed limiter removal region. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
