| 主权项 | 1. A drive axle system for a vehicle comprising: a drive axle assembly having first and second speed ranges that provide different drive ratios to a wheel; an axle shift unit configured to shift the drive axle assembly between the first and second speed ranges; and an inclinometer that detects inclination of the vehicle; wherein the axle shift unit is inhibited from shifting the drive axle assembly when inclination of the vehicle exceeds a threshold value that is indicative of a predetermined downhill road slope, wherein inclination of the vehicle is based on data from the inclinometer after a predetermined period of time has elapsed after shifting to a different speed range is requested. | ||
