Abstract
An HV-ECU performs a program including the steps of: determining whether or not the HV-ECU is in an auto-P execution state; determining whether or not a predetermined time period Tb has elapsed since an auto-P was requested; and permitting determination of the shifting operation if the HV-ECU is in the auto-P execution state and if it is determined that the predetermined time period Tb has elapsed since the auto-P was requested.
Claims8
A control apparatus for a vehicle including a drive wheel, a shift position selecting mechanism for selecting any one of a plurality of shift positions including a parking position by driving an actuator a parking lock mechanism for limiting rotation of said drive wheel if said parking position is selected by said shift position selecting mechanism, electrical equipment, and a power supply for supplying electric power to said electrical equipment, comprising:
- a power supply shutoff unit for shutting off electric power supply from said power supply to said electrical equipment if a shutoff instruction for said power supply is received and if said parking lock mechanism is in an effectively operating state;
- an actuator control unit for controlling said actuator such that said parking position is selected by said shift position selecting mechanism if said shutoff instruction is received;
- a prohibiting unit for prohibiting selection of a shift position different from said parking position based on an instruction from a driver, if said shutoff instruction is received;
- a lock determining unit for determining whether or not said parking lock mechanism is in the effectively operating state, if said shutoff instruction is received;
- and
- a permitting unit for permitting selection of the shift position different from said parking position based on the instruction from said driver, if selection of the shift position different from said parking position is prohibited by said prohibiting unit and if it is determined that said parking lock mechanism is not in the effectively operating state.
