Off-road clutch control

Abstract

A vehicle includes an engine, a primary axle drivably connected to the engine, and a secondary axle drivably connected to the engine by a clutch. A controller is programmed to, in response to map data indicating that the vehicle is off-road, enable an off-road transfer torque control mode in which temperatures of the clutch are compared to a lower threshold. The controller is further programmed to, in response to the temperature of the clutch exceeding the lower threshold, display a message to a driver indicative of rising temperatures of the clutch, and, in response to a temperature of the clutch exceeding an upper limit, enable a power limiting mode in which torque of the engine is limited to a predefined value.
