Patent ID: 7946404

Claim:
A work vehicle controller for a work vehicle having a forward clutch and a reverse clutch, the forward clutch terminating a clutching function thereof when a clutch oil pressure of the forward clutch reaches a holding pressure, and the reverse clutch terminating a clutching function thereof when a clutch oil pressure of the reverse clutch reaches a holding pressure, the work vehicle performing a shuttle operation and being configured such that an engine power is transmitted to a drive wheel via the forward clutch or the reverse clutch, the controller comprising: an operation unit operated to select a travel direction position from among a forward travel direction position, a neutral position, and a reverse travel direction position; a brake that reduces a vehicle body speed of the work vehicle; a vehicle body speed detector that detects the vehicle body speed; a forward/reverse clutch controller that controls the clutch oil pressure to disconnect the reverse clutch while connecting the forward clutch when the forward travel direction position is selected by the operation unit, and controls the clutch oil pressure to disconnect the forward clutch while connecting the reverse clutch when the reverse travel direction position is selected by the operation unit; a travel direction determination unit that determines whether a current travel direction of a vehicle body of the work vehicle is the forward travel direction or the reverse travel direction based on whether the clutch oil pressure of the forward clutch reaches the holding pressure thereof or the reverse clutch reaches the holding pressure thereof after switching the travel direction position of the operation unit; a braking force controller that controls a braking force of the brake such that the brake is activated when the travel position direction of the operation unit is switched if the travel direction position selected by the operation unit and the travel direction determined by the travel direction determination unit are opposite to each other and the detected vehicle body speed is greater than a predetermined threshold value.
