In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
These electricity storage systems for hybrid and engine functions include a lithium-ion battery with scalable capacity or a flywheel, a four to eight kilogram electric motor (with a maximum power level of 60 kW or 80 hp), as well as the KERS controller for power and battery management. Bosch also offers a range of electric hybrid systems for ...
Brembo's <BRBI.MI> distinctive colored brakes stop many of the world's fastest cars but when it comes to the electric vehicles of the future it faces a problem - traditional brakes are noisy.
Most mass-produced electric cars feature ESCs that capture energy when the car coasts or brakes, using the motor as a generator and slowing the car down. The captured energy is used to charge the batteries and thus extend the driving range of the car (this is known as regenerative braking). In some vehicles, such as those produced by Tesla ...
Transistors were used to replace the radio's audio output vacuum tubes and also the vibrator. This transistorized hybrid radio was available as an option on the 1956 Chevrolet Corvette car models. [6] In 1957, Delco produced an all-transistor signal-seeking car radio that was available for the 1957 Cadillac Eldorado Brougham car models. [7] [8]
Mobile players for physical media have been provided for vinyl records, 8-track tapes, cassette tapes, compact discs, and MP3s.The increased sophistication of the vehicle audio system to accommodate such media has made the audio unit a common target of car break-ins, so these are equipped with anti-theft systems too.

Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
