A 5-point harness in a racing car. Child held in a car seat by a five-point harness. A five-point harness is a form of seat belt that contains five straps that are mounted to the car frame. It has been engineered for an increase of safety in the occurrence of an automobile accident. As a result, this form of seat belt has been mandated in the ...
The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

Other forms of safety harnesses include seat belts and child safety seats in cars, which are helping passengers be and feel more safe in a car, Over-the-shoulder restraints, which are mainly used on roller coaster at amusement parks, a seat with a full-body harness like ones used by fighter pilots and racing car drivers, as well as diving ...
The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbuel and patented in 1919. [2] They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and sounding the horn.

The advent of concern about fuel economy and emissions had major impacts on engine design. Some of the trade-offs reduced throttle response. Most new cars employ a drive-by-wire system, which includes electronic throttle control and can itself either reduce or increase throttle response (Depending on whether or not it's being employed on a performance car).
Cold weather could lead to a surprise when you start your car in the morning: The colder weather can trigger a warning light in your car. Your car's low tire pressure light may come on this week ...
Fasten driver or passenger seat-belt (usu. with a buzzer) – Appears when the engine is switched and the driver's and/or passenger's seat belt is not buckled. A pressure sensor in the passenger seat prevents the passenger warning light from activating if the seat is unoccupied. Usually shaped like a person wearing a seat belt. [7]
