This invention generally relates to commercial vehicles, and more particularly to efficient operation of commercial vehicles for parcel delivery.
Commercial vehicles, such as parcel delivery vans, must have a long operational life, a low cost of ownership, and be safe work environments for the driver and handling personnel. The average commercial vehicle must be designed not only to withstand the wear and tear of making hundreds of stops every day, but also operate as efficiently as possible so to limit delivery time and provide the maximum value to the vehicle owner.
A typical commercial vehicle for parcel delivery has two main compartments. The first compartment is the cab compartment where the driver and handling personnel sit while the vehicle is driven from stop to stop. The second compartment is the cargo compartment. Access to the cargo compartment is achieved from two locations. The first location is from the rear of the vehicle via a roll-up or rear-swing door. The second location is the bulkhead door, which provides access to the cargo compartment via the cab compartment of the commercial vehicle.
The vehicle operators have a choice as to which cargo compartment access method they use when removing parcels. Typically, for larger parcels the rear access door is used because the rear door is larger than the bulkhead door. For smaller packages the vehicle operator(s) typically accesses the cargo compartment through the bulkhead door because it is more efficient for the operator to enter the cargo compartment directly from the cab of the vehicle as opposed to walking around to the rear of the truck for every stop.
Additionally, the vehicle operator has the choice of leaving the engine running once they arrive at the scheduled delivery location or shutting the engine off. Either choice is not ideal because if the operator leaves the engine running the vehicle will unnecessarily consume fuel and if they turn the engine off it will take several seconds to retrieve the key and restart the engine.
Because commercial vehicles used for parcel delivery will generally make hundreds of stops every day, and at each of those stops the operator will have to both shut the engine off and enter and exit the cargo compartment in order to obtain the parcel, efficient operation of the vehicle and efficient motion of the operator is extremely important. Accessing the cargo compartment of the vehicle efficiently and starting and stopping the vehicle engine efficiently saves delivery time, prevents unnecessary wear and tear on the vehicle, limits fuel consumption, and limits the potential for the operator to be injured by the repetitive nature of parcel delivery.
Typically, operation of a commercial vehicle used for parcel delivery entails the following processes. First, the operator must manually start the vehicle. Next the operator drives the vehicle to a scheduled delivery location. At the delivery location, the operator then must bring the vehicle to a stop, manually unlock the bulkhead door, manually open the bulkhead door, obtain the parcel, manually close the bulkhead door, deliver the parcel to the desired location, and finally restart the vehicle for the next delivery. A similar process is undertaken if the operator needs to use the rear door to access the cargo compartment as well. Additionally, the operator will pickup parcels at delivery locations. When parcels are collected, the operator will approach the vehicle with the parcel, manually unlock the bulkhead door, manually open the bulkhead door, deposit the parcel in the cargo compartment, and manually close the bulkhead door.
The delivery process described above presents several problems. The process of manually starting and stopping the vehicle, and unlocking, opening, and then closing the bulkhead door takes several seconds during each delivery and consumes fuel needlessly. Considering that the typical commercial vehicle used for parcel delivery makes hundreds of stops every day the additional time and fuel consumed at each delivery can be significant when viewed in the aggregate. Additionally, the repetitive motion of manually opening and closing the bulkhead door hundreds of times every day will cause damage to the vehicle and potentially harm the operator. Harm to the operator can come from the additional movement needed to unlock, open, and then close the door hundreds of times every day, and damage to the vehicle can come from the bulkhead door slamming open every time the cargo compartment is accessed.
In view of the above, there is a need for a cost efficient solution for operating a commercial vehicle that reduces the time and fuel consumed at each delivery and the potential harm to the vehicle and its operator. Embodiments of the invention provide such a solution for commercial vehicles. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
In view of the above, embodiments of the present invention provide new and improved commercial vehicle operation that overcome the problems existing in the art. More particularly, embodiments of the present invention provide new and improved operation of commercial vehicles for parcel delivery that overcome problems existing in the art. Still more particularly, embodiments of the present invention provide a new and improved way to control the ignition of the commercial vehicle and/or access the cargo compartment in a way that both minimizes damage to the vehicle, saves operator time, and reduces the likelihood of repetitive motion injury.
In one embodiment a control module is coupled to one or more of a commercial vehicle's ignition system, bulkhead door, and rear door. The control module controls these separate systems at the command of a vehicle operator communicating with the control module wirelessly through a transmitter.
Time is more efficiently managed, over the prior art, because movement is minimized in regard to starting and stopping the vehicle engine, opening the bulkhead door, and opening the rear door. Minimizing operator movement also has the added benefit of limiting the type of repetitive motion that can cause injuries to the operator over time.
Further, fuel consumed by leaving the engine running while at a delivery stop is minimized because the solution provides a quick and efficient way to turn the ignition off and on.
Finally, damage caused by the bulkhead door slamming opening is minimized. Damage is minimized because the door self actuates and has a dampening mechanism that keeps the door from slamming open and causing damage over time.
Additionally, in an embodiment of the present invention a lock box is attached to the vehicle. The lock box is securely closed and can only be opened by an individual with a key. Or if the box is locked via a combination lock only a person with the combination can unlock the box. The box is configured to hold a spare transmitter and/or an extra key to the commercial vehicle. The extra transmitter and/or key are to replace originals if lost or damaged.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
Turning now to the drawings, there is illustrated in
As may be seen from the embodiment illustrated in
In this particular embodiment of the invention, starting and stopping the commercial vehicle 100 and access to the cargo compartment 104 is optionally controlled through a transmitter 112 wirelessly communicating with a control module 110. As can be seen from
Specifically, the control module 110 is coupled to the commercial vehicle power supply 126, the vehicle ignition 118, a keyless ignition control module 120, a solenoid latch 122 for the bulkhead door 106, and a solenoid latch 124 for the rear door 108. The vehicle operator can operate the control module 110 by using the transmitter 112 in the vicinity of the commercial vehicle 100.
The transmitter 112 enables wireless control of any one or more of the commercial vehicle's ignition 118, bulkhead door 106, and/or rear door 108. The transmitter 112 in one embodiment will enable the engine to start or stop via a start/stop ignition control module 120 installed in the commercial vehicle 100. Also, the bulkhead door 106 can be opened automatically without the need to self-actuate the solenoid latch 122. Finally, the rear door 108 can be opened automatically without the need to self-actuate the solenoid latch 124.
It should be noted that while this particular embodiment of the present invention discloses operating the vehicle start/stop function and access to the cargo compartment wirelessly, manual overrides of the wireless system may still function. A traditional key that allows a operator to start and stop the commercial vehicle 100 and gives access to the cargo compartment through both the bulkhead door 106 and the rear door 108 may be employed in conjunction with an embodiment of the present invention.
Turning now to
In one embodiment the ignition control module 120 only operates in conjunction with transmitter 112 (see
Additionally, the bulkhead door 106 may be opened automatically upon stopping the engine of commercial vehicle 100. When the operator wants to stop the engine of the commercial vehicle 100 he depresses the stop button 204, and the commercial vehicle 100 shuts down. When the commercial vehicle 100 shuts down the operator may open the bulkhead door automatically by pressing the stop button 204 one additional time. The operator must perform the above sequence within a predetermined time period subsequent to shutting the commercial vehicle 100 down in order to enable this feature. When that time period expires control module 110 (from
The ignition control module 120 of the illustrated embodiment is not meant to entirely replace the traditional ignition 118, but rather only to supplement it. The traditional ignition 118 will still start and stop the commercial vehicle 100. The ignition control module 120, however, allows for a quicker starting and stopping process. In other embodiments, the ignition control module 120 may replace the traditional ignition.
Additionally, in the embodiments of the invention discussed herein, the objective of the auto-opening bulkhead door actuator 306 is to open the bulkhead door quickly enough that the operator does not have to wait to enter the cargo compartment. Further, not only must the bulkhead door 106 open quickly, but it must open fully so that the operator has an appropriate amount of room to easily move into and out of the cargo compartment. Even further, it is not enough that the bulkhead door 106 open quickly and fully, but it must also open safely in that it should not cause undue damage to the commercial vehicle 100 or the auto-opening bulkhead door actuator 306 in the process of opening.
Returning to
The inner retracting spring 506 is a resilient member that pulls the bulkhead door 106 open when solenoid latch 122 is actuated. The outer dampening spring 502 and inner dampening spring 504 dampen the retracting force of the inner retracting spring 506. The dampening is necessary to eliminate or limit damage to either the commercial vehicle 100 or the auto-opening bulkhead door actuator 306.
Specifically, slideable member 508, which is inside of the inner sheath 514, is connected to the inner retracting spring 506 and bracket 312 (from
In a particular embodiment of the present invention single stage dampening is used for the auto-opening bulkhead actuator 306. Single stage dampening occurs when just before the bulkhead door 106 slides completely open, the slideable member 508 makes contact with both the outer and inner dampening springs 502, 504. The outer and inner dampening springs 502, 504 dampen the force from the bulkhead door 106 opening so not to damage the auto-opening bulkhead door actuator 306 and/or the commercial vehicle 100, but still allowing the door to open quickly and fully.
Another embodiment of the present invention uses dual stage dampening. Dual stage dampening occurs when one spring, either the inner or outer dampening spring 504, 502 makes contact with the slideable member 508 prior to the other. As an example, the outer dampening spring 502 engages the slideable member 508 prior to the inner dampening spring 504. The outer dampening spring 502 is configured such that the opening speed of the bulkhead door 106 is largely decreased just prior to the bulkhead door 106 being entirely opened. And just prior to the bulkhead door 106 being entirely opened the inner dampening spring 504 engages to completely halt the rate at which the bulkhead door 106 is opening. The outer and inner dampening springs 502, 504 allow for the bulkhead door 106 to open quickly, fully, and minimize damage to the commercial vehicle 100 and/or the auto-opening bulkhead actuator 306 that would normally be caused from the bulkhead door 106 slamming open.
The solenoid latch 602 is communicatively coupled to control module 110 such that when the operator quickly presses button 114 of transmitter 112 twice the solenoid latch 602 actuates and allows the rear door 108 to slide up.
