The following specification particularly describes and ascertains the nature of this invention and the manner in which it is to be performed.
Field of Invention
[001] The invention relates to cabin locking system for commercial vehicles. It more particularly relates to safety systems for sensing and informing the vehicle operator about status of operation of the cabin lock provided on the driver cabins in commercial vehicles.
Background of the Invention
[002] In a typical commercial vehicle where the driver cabin is positioned directly above the engine compartment, access to said compartment accommodating the IC engine is obtained either through an ordinarily covered access opening in the front or from within the driver cabin or by lifting the driver cabin itself. In cases where mechanism for allowing driver cabin to be lifted has been provided in the commercial vehicle, it has been noticed that these mechanisms do not always reliably lock when lowered back into their ordinary working position. Cabin locks are therefore parts whose operational status needs to be monitored.
[003] This problem is ordinarily addressed by manually checking and rechecking the cabin lock after any repair work has been concluded in the vehicle space below the driver cabin. But this does not always cover for situations where the cabin lock for reasons, including human error, has malfunctioned thereby permitting dangerous articulation of the driver cabin about its rotation axis on the vehicle. There is currently no system that can sense and inform the vehicle operator about the operational status of the cabin locks. This is a serious issue because if the vehicle cabin rotates about its axis on the commercial vehicle when the vehicle is operating, the driver can loose control over the vehicle and the occupants of the driver cabin can also suffer injuries from getting thrown around or even out of the loose driver cabin.
[004] Additionally, any system for helping resolve this safety issue has to be reliable and economical so that it is readily accepted by buyers for being provided in all commercial vehicles with a cabin locking system. To help resolve this problem, an objective of the present invention is to provide an advanced cabin locking system with adaptive alerts for detecting and informing the vehicle operator about the status of the cabin lock provide on the commercial vehicle.
[005] It is another objective of the present invention to provide an advanced cabin locking system with adaptive alerts that is reliable.
[006] It is still another objective of the present invention to provide an advanced cabin locking system with adaptive alerts that is economical to provide.
[007] It is yet another objective of the present invention to provide an advanced cabin locking system with adaptive alerts that improves safety of operation of commercial vehicles.
[008] It is also another objective of the present invention to provide an advanced cabin locking system with adaptive alerts that reduces the possibility of people getting injured because of the cabin lock not being locked properly on the commercial vehicle.
Summary of the Invention
[009] An embodiment of the invention achieving the stated objective, that is advanced cabin locking system with adaptive alerts, comprises of a tactile switch, a battery, a buzzer, a resistor, an LCD display, hazard lamp. In the advanced cabin locking system with adaptive alerts, one terminal of the tactile switch is electrically linked with one terminal of the battery though an electrical connection.

[0015] Second terminal of the battery (10) (refer to Fig. 1) is electrically connected with one terminal of the buzzer (20) through an electrical connection. second terminal of the battery (10) is also connected to two terminals of the LCD display (40) through an electrical connection, second terminal of the battery (10) is also connected to one terminal of the hazard lamp (50) through an electrical connection.
[0016] The second terminal of the buzzer (20) (refer to Fig. 1) is connected to the second terminal of the tactile switch (5) through an electrical connection. The tactile switch (5) is a normally open switch which closes if the unlocking lever of the cab is not securely locked. The third terminal of the LCD display (40) is connected to the second terminal of the tactile switch (5) through the resistor (30) via an electrical connection. The second terminal of the hazard lamp (50) is also connected to the second terminal of the tactile switch (5) through the resistor (30) via an electrical connection. The resistor (30) is a 1 KW resistor.
[0017] The electrical connection to the one terminal of the buzzer (20), two terminals of the LCD display (40), one terminal of the hazard lamp from the second terminal of the battery (10) is also connected to a negative terminal (power supply(-)) of the ignition system of the vehicle. The power supply (+) connection and the power supply (-) connection leading to the ignition system of the vehicle enable inputs on the state of the tactile switch (5) to be transmitted to the VMU/ECU of the vehicle.
