Abstract:
1. A vehicle parking system, comprising: a parking lock mechanism that is provided in a drive power transfer system of a vehicle, that includes a first electromagnetically-driven actuator which is operated by electric power supplied from a power supply unit, and that mechanically interrupts rotation of a drive power transfer shaft, which transfers drive power from a drive power source of the vehicle to a drive wheel, by operating the first electromagnetically-driven actuator; a parking brake mechanism that includes a brake provided to the wheel of the vehicle and a second electromagnetically-driven actuator which is operated by electric power supplied from the power supply unit, and that applies the brake by operating the second electromagnetically-driven actuator to suppress rotation of the wheel; and an electromagnetically-driven actuator control unit that starts the first electromagnetically-driven actuator and the second electromagnetically-driven actuator at staggered times, when both the parking lock mechanism and the parking brake mechanism are operated based on a predetermined operation command, wherein the electromagnetically-driven actuator control unit includes a peak consumption current-based electromagnetically-driven actuator control unit that first starts the first electromagnetically-driven actuator of the first electromagnetically-driven actuator and the second electromagnetically-driven actuator, wherein a peak value of the electric current consumed in the first electromagnetically-driven actuator is smaller than a peak value of the electric current consumed in the second electromagnetically-driven actuator.
