A vehicle control system includes a first powertrain, a second powertrain, and a third powertrain. The first powertrain includes a first power source. The second powertrain includes a second power source. The third powertrain includes a third power source. The vehicle control system also includes an operator control interface. The operator control interface includes a first portion configured to receive a first operator input and a second portion configured to receive a second operator input. The first operator input and the second operator input are indicative of a desired speed and a desired direction. The vehicle control system additionally includes a controller configured to deliver a power control signal to at least one of the first powertrain, the second powertrain, and the third powertrain. The power control signal is a function of the first operator input and the second operator input.

Vehicle control system and method

A blowby mist separator and regulator system for an enclosed crankcase of an internal combustion engine having a submicron mist separator and vacuum regulating valve disposed in a horizontally oriented cylindrical housing connected in fluid communication with the crankcase and an air intake manifold to maintain a vacuum within the crankcase, continuously return separated coalesced mist to the crankcase and prevent cylinder blowby from escaping to the atmosphere and having a pressure sensor in the crankcase, which cooperates with a high pressure indicator to indicate when the pressure within the crankcase becomes positive and blowby gases could be released into the atmosphere if the mist separator is not replaced.

Engine barring devices are connected to engines. Known barring devices have been used to rotate crankshafts of engines and adding features to these known devices increases the complexity and cost of such devices. The subject barring device includes a shaft adapted for both axial and rotational movement. A gear is attached to one end of the shaft and is moved axially in a first direction to a first position where a holding device holds the shaft in the first position. In the first position the gear is engaged driving with a flywheel connected to the crankshaft of the engine. A tool engaging portion located on the shaft is adapted to engage with a turning tool. With the shaft in the first position, the turning tool can be used to rotate the crankshaft of the engine. A locking device is included to hold the crankshaft in one of the plurality of rotational positions. The subject barring device provides a holding device to hold the shaft in the first position, a device to disable the activation of a starting system, a tool engaging portion allowing rotation of the shaft and a locking device to lock the shaft in one of a plurality of rotational positions.
