When a vehicle driver operates a momentary-type gear shift lever and the lever continuously stays for not less than a predetermined length of time at a target gear position, in R, D, and N positions, corresponding to a target shift range of the automatic transmission of a vehicle, a shift range switching apparatus judges that the lever is operated to the target gear position and instructs a DC motor to switch to the target shift range of the automatic transmission. The apparatus detects a busy shift (or incomplete) operation of the lever based on voltage signals transferred from vertical/horizontal direction sensors corresponding to the current position of the lever. The apparatus detects the occurrence of the bush shift (or incomplete) operation when the gear shift lever is returned to the original position after being operated from the original position toward the target gear shift position, but, does not reach it. |
