The car may only have one gear ratio, and the motor simply runs in the opposite direction to make the car go in reverse. Some electric cars with DC motors also have this feature, using an electrical switch to reverse the direction of the motor, but others run the motor in the same direction all the time and use a traditional manual or automatic ...
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).

Structure of a series-hybrid vehicle. The grey square represents a differential gear. An alternative arrangement (not shown) is to have electric motors at two or four wheels. Series hybrids are also referred to as extended-range electric vehicles (EREV) [5] or range-extended electric vehicles (REEV), or electric vehicle with extended range ...
Traction motors are used in electrically powered railway vehicles (electric multiple units) and other electric vehicles including electric milk floats, trolleybuses, elevators, roller coasters, and conveyor systems, as well as vehicles with electrical transmission systems (diesel–electric locomotives, electric hybrid vehicles), and battery ...
Saab's Sensonic system was electro-hydraulic, using an electric motor or solenoid connected to a hydraulic clutch actuator, whereas Ferrari's Valeo system was electro-mechanical, using an electric motor or solenoid, connected to the mechanical clutch system. [8] [9] [10] Similar TCU or GCU systems are used in racecars with paddle-shift ...
An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system , with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels , or by converting fuel to electricity using fuel cells or a generator ).
Vehicles having a hydrodynamic coupling, hydrodynamic torque multiplier or electric motor as part of the power transmission system may also have a maximum continuous tractive effort rating, which is the highest tractive force that can be produced for a short period of time without causing component harm.
Park-by-wire can be considered a part of a shift by wire system, as it shifts the transmission into park mode. [1] The main components of a park by wire system include the driver interface which could be a lever, switch, or knob; an electronic control unit ; and actuators which are capable of driving the parking pawl into and out of the locking ...
