Vehicle and control method for vehicle

摘要

A vehicle includes a shift sensor and an ECU that switches a shift range based on a combination of shift signals received from the shift sensor. The ECU includes a determining unit and a switching unit. The determining unit determines, based on how a shift signal pattern has changed (the number and type of shift signals that have changed), whether or not to execute first fail-safe traveling in which a shift range before occurrence of a shift abnormality is maintained. In the event of a shift abnormality, in a case where execution of the first fail-safe traveling is permitted, the switching unit executes the first fail-safe traveling to maintain a shift range before occurrence of the shift abnormality, and in a case where execution of the first fail-safe traveling is prohibited, the switching unit executes second fail-safe traveling to switch a shift range to an N range.

主权项

1. A vehicle comprising:
a shift sensor that outputs a plurality of shift signals, said shift signals being output in accordance with a shift manipulation by a user; and a control device that controls a shift range in accordance with a combination of said shift signals, said control device monitors a change in said shift signals and, in the event of a shift abnormality where a combination of said shift signals after a change corresponds to none of a predefined plurality of combinations, executes, when the number of changes in said shift signals is equal to or less than a threshold value, first fail-safe traveling in which the shift range before occurrence of said shift abnormality is maintained, and prohibits execution of said first fail-safe traveling when a number of changes in said shift signals is greater than said threshold value.
