Abstract
An HV-ECU executes a program including a step (S102) of turning on a fail-safe permission flag if a select sensor is abnormal (YES in step S100), and a step (S108) of transmitting a non-P request signal to a P-ECU if the position of a shift lever is read as the N position (YES in S104) and a predetermined time Tn(2) elapses (YES in S106).
Claims2
A shift switching device comprising a first detection unit detecting a position of a shift lever in a first direction and a second detection unit detecting a position of said shift lever in a second direction, for switching a shift position of a transmission mounted in a vehicle based on the position in the first direction and the position in the second direction, wherein
- said shift position includes at least a parking position, and
- said shift switching device releases said parking position if said shift lever is manipulated in said second direction, and maintains said parking position if said shift lever is not manipulated in said second direction, when said first detection unit is abnormal.
