Abstract
An engine brake control system for a vehicle provided with a variable-speed V-belt drive ( ) including a drive pulley ( ) and a gear transmission ( ) disposed below the variable-speed V-belt drive ( ) with respect to a power transmitting direction comprises a traveling speed sensor ( ), a traveling mode discriminating sensor ( ), an engine brake device capable of making engine brake effective by restricting the decrease of the effective diameter of the drive pulley while the vehicle is traveling at a traveling speed not lower than a predetermined traveling speed, and an engine brake control system which makes engine brake ineffective by removing restriction on the decrease of the effective diameter of the drive pulley ( ) while the traveling mode discriminating sensor is providing a signal indicating that the vehicle is traveling in a reverse travel mode. The traveling mode discriminating sensor ( ) is disposed opposite to a detection rotor ( ) attached to a rotating member and provided with at least three projections ( ) arranged at unequal angular intervals.
