ABSTRACT:
A speed control system for a vehicle having a braking device and a stepless transmission. A change speed member for controlling the stepless transmission is shiftable between a forward drive zone and a backward drive zone across a neutral position. The change speed member is urged to the neutral position, and operatively connected to a change speed pedal and a shift lever. The shift lever is lockable to a selected shift position. Switching may be made between a connection enable state for enabling connection between a first interlocking member connected to the change speed member and a second interlocking member connected to the shift lever, and a connection prohibit state for prohibiting the connection between the first interlocking member and second interlocking member.
The connection between the first interlocking member and second interlocking member is canceled with operation of the braking device. When the connection enable state is set, the first interlocking member and second interlocking member are connected to each other by shifting of the change speed pedal after the operation of the braking device, to reinstate a vehicle speed corresponding to a shift position of the shift lever selected prior to the operation of the braking device.
