Motor vehicle with system for conditioning power take-off enablement on an engine compartment being closed
View Patent ↗A motor vehicle with a system for conditioning power take-off enablement has a powerplant, including an internal combustion engine, for propelling the vehicle. The powerplant is disposed within a compartment. A hood is positionable relative to the compartment to selectively allow and disallow access to the compartment. A power take-off unit comprises an input mechanically coupled to the powerplant and selectively enabled by a controller for coupling an output of the power take-off unit to the input of the power take-off unit when enabled by the controller and uncoupling the output of the power take-off unit from the input of the power take-off unit when not enabled by the controller. A device whose status distinguishes between the hood allowing access to the compartment and the hood disallowing access to the compartment causes the controller not to enable the power take-off unit when the device discloses that the hood is allowing access to the compartment.
1. A motor vehicle with a system for conditioning power take-off enablement, the motor vehicle comprising:
a powerplant, including an internal combustion engine, for propelling the motor vehicle;
a compartment within which the powerplant is housed;
a hood that is positionable relative to the compartment to selectively allow and disallow access to the compartment;
a power take-off unit that comprises an input mechanically coupled to the powerplant and that is selectively enabled by a controller for coupling an output of the power take-off unit to the input of the power take-off unit when enabled by the controller and uncoupling the output of the power take-off unit from the input of the power take-off unit when not enabled by the controller;
a device whose status distinguishes between the hood allowing access to the compartment and the hood disallowing access to the compartment for causing the controller not to enable the power take-off unit when the device discloses that the hood is allowing access to the compartment; and
an electrical power unit for delivering electricity to electrically-operated equipment associated with the motor vehicle and in which the electrical power unit is selectively enabled by a signal from the power take-off unit disclosing that the power take-off unit is being enabled by the controller.
2. The motor vehicle as set forth in claim 1 further comprising:
a display operatively associated with the device for visually disclosing status of the device.
3. The motor vehicle as set forth in claim 1 in which the powerplant includes an electric motor-generator cooperatively arranged with the internal combustion engine in a parallel hybrid configuration.
