An apparatus and method for simultaneously operating the horn and light systems of a motorized vehicle is provided. The controller used to operate the systems can be a single controller that operates the horn when a certain range of pressure is applied to the controller and operates the horn and lights systems when a stronger pressure is applied. The system can include a dedicated horn operating system controller independent of the dual function controller to eliminate the need for differing pressures to operate the horn and light systems substantially simultaneously. Also disclosed are apparatuses and methods to coordinate a vehicle braking system with the vehicle horn and light systems to improve the reception of safety and/or emergency warnings.

Various implementations of a horn system include one or more force sensors disposed on a first portion of a driver air bag module and one or more actuators disposed on a second portion of the driver air bag module. For example, the force sensors may be disposed adjacent a perimeter of a base plate of the driver air bag module, and the actuators may extend inwardly toward the force sensors from an inner surface of a cover of the driver air bag module, or vice versa. To actuate the horn, the cover is moved axially toward the base plate, causing the actuators to apply force to the force sensors. Force signals received from the force sensors are used by one or more processors to determine characteristics of the force received and/or select a control message for communicating to the horn system based on the force signal characteristics.

A safety system includes a vehicle having a cab and a compartment rearward of the cab, an engine that provides motive power to the vehicle, a generator positioned in the vehicle so as to supply electrical energy to the compartment, an alarm positioned in or on the vehicle so as to be cooperative with the engine and the generator, an alarm acknowledge switch positioned in or on the vehicle, a shore power connection on the vehicle, and a control module positioned in or on the vehicle so as to selectively activate or deactivate the alarm or to deactivate the generator when certain conditions occur. The generator has an on/off switch so as to turn the generator either on or off. The alarm is activated when the generator is turned on and the engine is not running. The alarm acknowledge switch is activatable as to turn the alarm off. The shore power connection is adapted to be connected to a source of electrical energy exterior of the vehicle.

A vehicle audio output device and light system accommodating sounding the vehicle audible output device and illuminating one or more vehicle exterior lights when a user-operated button is pressed. The electrical circuit includes a battery electrically connected to a horn and light computer. The computer includes a processor and an input/output interface. The system circuit further includes a user-operated button electrically connected to the battery, to a vehicle horn, and to an input port of the system computer. The system computer is electrically connected to a light relay module via an output port, and the light relay module is connected to a vehicle exterior light. The system computer processor can be programmed to illuminate or flash the exterior light as desired. The system may further include a vehicle audio output device and light system switch and may also include a vehicle main computer electrically connected to the light relay module.

A panic device operable in conjunction with a local device is configured to unlock a locking mechanism. The panic device can take the form of an electronic key fob, a key shaft, or a key holder. A first trigger on the panic device triggers a local alarm that is on-board or off-board the panic device. A second trigger on the panic device can activate an alarm circuitry that utilizes a local device to provide position information to a distant dispatch station. The local device uses a GPS-aware circuitry or other non-GPS means such as triangulation to determine the position information. The position information can then be sent to the distant dispatch station with or without the aid of the local device.

A vehicle zone control system may include a tractor having a propulsion unit and a steering unit, at least sensor carried by the tractor and stored data defining a plurality of zones proximate the vehicle. The system determines in which of the plurality of zones a remote operator on ground proximate the tractor currently resides based upon signals from the at least one sensor. The system differently controls at least one of the propulsion unit and the steering unit based upon in which zone the remote operator currently resides.

A circuit for disabling an electric device stuck in an active state. The circuit includes a first input for receiving a first actuation signal from an external device and a second input for receiving a second actuation signal from a microcontroller. An output path is connected to the first input and the second input and transmits the first actuation signal and the second actuation signal to the electric device. A grounding path transmits the first actuation signal and the second actuation signal to ground. A first transistor is disposed on the grounding path and is configured to be activated by a first voltage potential. A first latching circuit is coupled to the battery and is configured to receive the pulsed signal from the microcontroller and ground the first actuation signal and the second actuation signal along the grounding path so as to disable the electric device.

A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

A system for noise exposure management. In one example, a system includes at least one speaker and a controller operatively coupled to the at least one speaker. The controller is configured to turn on and turn off the at least one speaker. The system is further configured to reduce a sound intensity of siren sounds generated by the at least one speaker when the at least one speaker is turned on in response to a signal received by the controller. The signal is generated in response to a cumulative sound exposure, over a period of time, that exceeds a predefined sound exposure magnitude.

A multi-position turn signal system for vehicles includes a turn signal lever movable between a neutral-position, primary-positions, and secondary-positions. The primary-positions activate standard turn signals, while the secondary-positions indicate multi-lane changes. In some configurations, the system may incorporate electronic integration with vehicle sensors, auxiliary indicators, or variable duration signaling. The system enhances communication of driver intent during complex lane change maneuvers, improving safety in multi-lane traffic scenarios.
