Vehicle parking control system

A vehicle parking control system for a vehicle with a drive unit and a range selection device, the drive unit including an output shaft that is connected through a rotating member to a wheel of the vehicle and a lock mechanism that disengageably engages the output shaft to prevent the output shaft from rotating, and the range selection device being operated by an operator that is capable of selecting a driving range and a Park range, which is a non-driving range, of the drive unit, comprising:

• a shift-by-wire apparatus that is operated based on an electric range position signal corresponding to one of the driving range and the Park range, which is the non-driving range, of the drive unit and that switches the lock mechanism to an engaged state and a released state in conjunction with a switching of one of the driving range and the Park range, which is the non-driving range, of the drive unit;
• a vehicle parking brake unit that is operated based on the range position signal and that switches a brake unit, which is provided to stop a rotation of the rotating member of the vehicle, between a braking state and a released state;
• and
• a control unit that operates the shift-by-wire apparatus to switch the lock mechanism to the released state when the range position signal is a signal to switch a shift range out of the Park range, which is the non-driving range, and the vehicle parking brake unit to switch the brake unit to the released state at one of a time when the lock mechanism is set to the released state and a time after the lock mechanism is set to the released state.
