The present invention relates to a vehicle wiper gearbox and a vehicle wiper drive system. The gearbox comprises a transmission gear installed in the gearbox and provided with an actuating part; a first parking signal terminal and a second parking signal terminal which are electrically conductive and are arranged in a spaced manner; and a metal drive part comprising an actuated part and a moving terminal which are fixed together. When the transmission gear rotates towards a positive direction, the actuated part can be actuated by the actuating part of the transmission gear to drive the driven part to rotate, and the moving terminal changes electric conductive states between the two parking signal terminals at at least one parking position within a rotating cycle of the driven part. When the transmission gear rotates towards a negative direction instead of the positive direction, actuation of the actuating part is away from the actuated part, and thus the driven part is not driven. The problem that a wiper joggles after meeting foreign matters during closing is solved, the wiper gearbox is compact in structure, and die costs, installation procedures and labor costs are reduced.
