Keyless access for commercial vehicles

Abstract

A commercial vehicle used for parcel delivery is installed with a control module. The control module communicates wirelessly with a transmitter to give control to the vehicle operator. The vehicle operator can access the vehicle's cargo compartment through the bulkhead door and/or the rear door solely by using the transmitter as opposed to manually actuating the door latch. A door actuator is added to the bulkhead door such that when the bulkhead door is wirelessly actuated the door opens without operator assistance, and the process of the door opening does not damage the vehicle. Additionally, the vehicle operator can initiate the control module to allow a push-button start and stop of the vehicle's ignition system. Such elements contribute to time savings and cost savings for parcel delivery operators.

DETAILED DESCRIPTION OF THE INVENTION

(12) Turning now to the drawings, there is illustrated in FIG. 1 a commercial vehicle 100 installed with a particular embodiment of the present invention. It should be noted, however, that while the following description will describe various embodiments and aspects of the various embodiments of the present invention configured for a commercial vehicle, the scope of the present invention is not so limited. Indeed, many of the aspects of the present invention may find applicability in other applications, in other commercial vehicles other than ones used strictly for parcel delivery. As such, the following description should be taken by way of example and not by way of limitation.

(13) As may be seen from the embodiment illustrated in FIG. 1, the commercial vehicle 100 has two main compartments. The first compartment is the cab compartment 102. The cab compartment 102 is where the vehicle operation personnel sit while the commercial vehicle 100 is in use. The second compartment is the cargo compartment 104. Access to the cargo compartment 104 is achieved through two separate entry ways. The first method of access is through the rear door 108. The second method of access is through the bulkhead door 106.

(14) 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 FIG. 1 the control module 110 is installed in the commercial vehicle 100 and is communicatively coupled to several systems of the commercial vehicle 100.

(15) 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.

(16) 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.

(17) 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 an 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.

(18) Turning now to FIG. 2, the ignition control module 120 is shown in more detail. The ignition control module 120 is installed in the dash 206 of commercial vehicle 100 in order to provide easy access to the vehicle's operator. The commercial vehicle ignition 118 is controlled by the start button 202 and the stop button 204.

(19) In one embodiment the ignition control module 120 only operates in conjunction with transmitter 112 (see FIG. 1). Specifically, to start the commercial vehicle 100 an initiation signal must be sent from the transmitter 112 to the control module 110. The initiation signal is sent when the operator presses button 114 on the transmitter 112 within the vicinity of commercial vehicle 100. This readies the ignition control module 120. Now the operator needs only to press the start button 202 of ignition control module 120 shown in FIG. 2 once to start the commercial vehicle 100. To stop the commercial vehicle 100 the operator only needs to press the stop button 204 of the ignition control module 120.

(20) 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 be 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 FIG. 1) resets the system to prevent unauthorized access to the cargo compartment.

(21) 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.

(22) FIG. 3 illustrates the bulkhead door 106, as viewed from the cargo compartment 104. The bulkhead door 106 is operated by solenoid latch 122 and auto-opening bulkhead door actuator 306. The auto-opening bulkhead door actuator 306 is anchored to the cargo compartment 104 by brackets 308, 310 and attached to the bulkhead door 106 by bracket 312 (as shown in FIG. 3A). When the solenoid latch 122 is released the auto-opening bulkhead door actuator 306 pulls the bulkhead door 106 open. The solenoid latch 122 is released in one embodiment when the operator depresses button 114 on transmitter 112 (see FIG. 1) for a predetermined period, e.g., over one-half second, as opposed to briefly pressing once to activate the ignition control module 120 in an embodiment that provides such operation.

(23) FIG. 4 illustrates an up-close view of the solenoid latch 122. The solenoid 402 is connected via the solenoid connector arm 404 to lever 406. Solenoid latch 122 operates by a control signal being provided to solenoid 402 from control module 110 of FIG. 1, which actuates the solenoid connector arm 404 to pull the lever 406 thereby unlatching the bulkhead door 106.

(24) FIG. 5 illustrates a cross-sectional view of an embodiment of the auto-opening bulkhead door actuator 306. While this particular embodiment of the invention illustrates using springs in the auto-opening bulkhead door actuator 306 other methods of opening the bulkhead door 106 are contemplated. Some of the other methods contemplated are electric motor controlled openers, and any hydraulic openers or pneumatic openers, or any equivalent thereof.

(25) 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.

(26) Returning to FIG. 5, three springs are contained inside of an inner sheath 514 and an outer sheath 512. The outer sheath is attached to the cargo compartment by bracket 308 and bracket 310, while the inner sheath 514 connects to the bulkhead door via bracket 312. (See FIGS. 3 and 3A). Therefore, the inner sheath 514 is capable of moving and the outer sheath 512 is stationary when installed in the illustrated embodiment.

(27) 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.

(28) Specifically, slideable member 508, which is inside of the inner sheath 514, is connected to the inner retracting spring 506 and bracket 312 (from FIG. 3A) by the connecting member 516. Therefore, when the bulkhead door is closed the inner retracting spring 506 is stressed such that when solenoid latch 122 is actuated the inner retracting spring 506 retracts pulling the inner sheath 514, the slideable member 508, and the bulkhead door 106 itself open.

(29) 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.

(30) 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.

(31) FIG. 5A shows an exploded view of the auto-opening bulkhead door actuator 306. Notice how the longest resilient member is the inner retracting spring 506, the next longest is the outer dampening spring 502, and the shortest is the inner dampening spring 504. Also, the inner retracting spring 506 the inner dampening spring 504, and the outer dampening spring 502 all are contained within the inner sheath 514, which has a smaller diameter than the outer sheath 512. Both sides of the auto-opening bulkhead door actuator 306 are contained by the base plug 510 on one end and the slideable member 508 on the other.

(32) FIG. 6 illustrates the rear door assembly 600. In this embodiment of the invention, the rear door assembly 600 is composed of a roll-up rear door 108, solenoid latch 602, cable 604, and manual cam lock 606.

(33) 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. FIG. 6 also displays a manual cam lock 606, which causes the solenoid latch 602 to actuate when the operator rotates the manual cam lock 606 by inserting a key and turning. The turning motion in cam lock 606 causes cable 604 to actuate the solenoid latch 602.

(34) FIG. 7 illustrates a particular embodiment of the invention that includes a lock box 700. The lock box 700 is attached to the commercial vehicle 100 and contains a second transmitter 712 in case the first transmitter 112 is lost. The lock box 700 is opened via a locking device 702. FIG. 7 displays a push-button locking device; however, other locking devices such as latch and key devices are contemplated as well.
