A vehicle is operable in a first mode in which vehicle actions are controlled in response to inputs received by an input device carried by the vehicle from an operator while being boarded on the vehicle and in a second mode in which vehicle actions are controlled in response to inputs received from the operator while the operator is proximate the vehicle, but no longer boarded on the vehicle. The vehicle carries a sensor configured to output a sensed input, as sensed by the sensor, from the operator proximate the vehicle, but not boarded on the vehicle. The sensed input is recognized and associated with a vehicle action and control signals are output to the vehicle based on the sensed input to cause the vehicle to carry out the vehicle action.

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 handcart may include a drive wheel; a prime mover configured to rotate the drive wheel; a grip portion configured to be gripped by a user; and a visibly noticeable portion that is clearly noticeable from behind the user when the user stands behind the handcart, gripping the grip portion.

A driving control device receives power supply from an accessory battery to operate, controls automatic driving, and outputs a control signal. A steering ECU, a power ECU and a brake ECU instruct a steering mechanism, a PCU and a brake to operate based on the control signal, respectively. An emergency stop switch is operated by an operator. In a case where the emergency stop switch is operated, an interface processing device cuts off a switch to stop the power supply, shuts down the driving control device, and outputs a control signal that causes the steering mechanism, the PCU and the brake to perform an emergency stop operation.

A vehicle control system may include a vehicle having a propulsion unit and a steering unit, a forward-facing camera carried by the vehicle, a processor, and a non-transitory computer-readable medium comprising operator position identification instructions. The operator position identification instructions direct the processor to identify relative positioning of a remote operator on the ground proximate the vehicle based upon signals from the forward-facing camera; and control the propulsion unit and the steering unit of the vehicle to follow the operator based upon the relative on the ground proximate the vehicle.

A vehicle system to produce audible sound includes at least one auxiliary motor to mechanically operate of a vehicle component based on a control signal and to produce an audible sound without mechanically operating the vehicle component, and a controller to output a motion control signal to control operation of the at least one auxiliary motor and to output an auditory control signal to actuate the at least one auxiliary motor to produce the audible sound. A waveguide is provided in communication with the at least one auxiliary motor and in sonic resonance with sound produced by the auxiliary motor to amplify and/or to modify the audible sound.

The present disclosure relates to a car audio information transmitter, including: a main controller, an audio receiver, an audio, transforming module, a wireless transmitter, and a frequency adjustment module. The audio receiver connects to the main controller. The audio transforming module connects to the audio receiver and is configured to transform the audio signals. The wireless transmitter connects to the audio transforming module and is configured to transmit the transformed audio signals to a wireless receiver of a car. The frequency adjustment module connects to the audio transforming module and is configured to adjust a frequency of the audio signals. The car audio information transmitter is capable of accessing to the adjusting mode by one operation and adjusting an amplitude of the audio signals. As such, the complicated operations may be avoided, and the driving safety may be improved.

A road safety electronic sound system for quiet vehicles including a capsule in the approximate shape of a cylinder, the lateral surface of the capsule includes a partial mesh grille and a connection terminal. The capsule also includes a pair of push buttons on one of the bases and a microcontroller inside. The microcontroller is connected to: a power supply; the pair of push buttons for programming the functions of the microcontroller; the connection terminal for connecting it to an outer housing; a speaker; and a movement sensor. The microcontroller by means of the speaker is able to emit a permanent sound, which can be turned off, when the microcontroller detects, by means of the sensor, movement in the surroundings of the electronic system itself.

Dual-tone horn assemblies and methods of use are disclosed herein. An example dual scroll assembly includes a nozzle having a first portion of the nozzle has a first diameter and a second portion of the nozzle has a second diameter that has a size that is different from the first diameter, a first spiraled channel that receives air from the first portion of the nozzle. The air traveling through the first spiraled channel produces a first tone at a first frequency. A divider plate is disposed between the first spiraled channel and a second spiraled channel. The second spiraled channel receives the air from the second portion of the nozzle. The air traveling through the second spiraled channel produces a second tone at a second frequency. The first tone and the second tone when produced simultaneously create a dyad.
