Torque Distribution Strategy for a Front- and Rear-Wheel-Driven Electric Vehicle Abstract: Electric vehicles EVs with a distributed drive train configuration offer great potential and flexibility for improving system efficiency, performance, reliability, and safety. This paper investigates a torque distribution scheme for a front- and rear-wheel-driven microsized EV to improve drive train efficiency over a wide torque and speed range.

Adaptive electronic differential control of vehicle by torque balance

Power-to-weight ratio PWR also called specific power , or power-to-mass ratio is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight or mass of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio power loading is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle.

Squirrel cage induction motors are employed in a wide variety of applications. Operating at constant speed is required in some applications, whereas variation of this parameter is required in others, as in the provision of mechanical energy to electrical vehicles. The performance of an electric vehicle is specified by the characteristics of the electric motor. The adequate relation between the voltage magnitude and the frequency of its power source makes the motor satisfy the electric vehicle requirements. The voltage magnitude is a function of the frequency of operation. If the V - f relation is adequate, the motor speed response could be improved. A new V - f relation that improves the speed response of the single squirrel cage induction motor is presented and is defined by a frequency factor.

This chapter provides an overview of the various elements that determine fuel consumption in a light-duty vehicle LDV. The primary concern here is with power trains that convert hydrocarbon fuel into mechanical energy using an internal combustion engine and which propel a vehicle though a drive train that may be a combination of a mechanical transmission and electrical machines hybrid propulsion. A brief overview is given here of spark-ignition SI and compression-ignition CI engines as well as hybrids that combine electric drive with an internal combustion engine; these topics are discussed in detail in Chapters 4 through 6. The amount of fuel consumed depends on the engine, the type of fuel used, and the efficiency with which the output of the engine is transmitted to the wheels. This fuel energy is used to overcome 1 rolling resistance primarily due to flexing of the tires, 2 aerodynamic drag as the vehicle motion is resisted by air, and 3 inertia and hill-climbing forces that resist vehicle acceleration, as well as engine and drive line losses.

Electric power is widely used in electric traction for many reasons: it is easy to control the speed of an electric motor, the absence of exhaust gases, free of noise, it has high starting torque, and it needs less maintenance than its mechanical counterpart. In the current research, a modern hybrid car is designed and manufactured in three ways. The second method is to take advantage of the solar energy which is almost available in Iraq environment throughout the year to be stored in the batteries, especially during the shutdown of the machine and when it stops it under the sun. The third method is the mechanical energy by using the bicycle pedal to move the wheels of the car; it is useful in the event of a sudden interruption of electrical power or a technical failure in the vehicle. In addition, three kinds of electronic devices are used for control. The first control is electric battery charger. The second control is to convert solar radiation into electrical energy to be stored in the batteries.

Current adaptive torque balancing control of electric wheel-driven vehicle has shortcomings in electronic differential control of drive motor by using rotation speed mode. In order to solve this problem, an adaptive electronic differential control method of electric wheel-driven vehicle is proposed in this paper by torque balance. Firstly, by starting from the kinematics and dynamics of vehicle steering, the speed and force of each drived wheel in the steering are analyzed to explain the auxiliary role of electronic differential control to adaptive torque balancing, as well as influence of steering radius in vehicle. Then, electronic differential distribution by torque of wheel is used to control the abnormal jump interference and calculate the optimal combination of parameters in electronic differential control system. Finally, based on the optimal combination of these parameters, an adaptive electronic differential control of electric wheel-driven vehicle by torque balance is realized with fuzzy control in active and the reactive power.

Transmission (mechanics)

This site deals with Direct Current permanent magnet motors operated at a constant voltage. Motor characteristics vary considerably from type to type, and their performance characteristics can be altered by the way electrical power is supplied. Section 2.

Сьюзан набрала полные легкие воздуха и задала неизбежный вопрос: - И где же теперь этот канадец. Стратмор нахмурился: - В этом вся проблема. - Офицер полиции этого не знает. - Не имеет понятия. Рассказ канадца показался ему полным абсурдом, и он подумал, что старик еще не отошел от шока или страдает слабоумием.

В руке Хейл сжимал беретту. Вскрикнув, она оторвала взгляд от неестественно выгнутой руки и посмотрела ему в лицо. То, что она увидела, казалось неправдоподобным. Половина лица Хейла была залита кровью, на ковре расплылось темное пятно. Сьюзан отпрянула.

Vehicle acceleration and maximum speed modeling and simulation

 Вы набрали правильно, - сказал он осторожно, - но это служба сопровождения. Звонивший некоторое время молчал. - О… понимаю.

 У них там прямо-таки дискотека! - пролопотал Бринкерхофф. Фонтейн смотрел в окно, пытаясь понять, что происходит. За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал .

Mechanical and Electrical Design Calculations of Hybrid Vehicles

 Не существует алгоритма, не поддающегося взлому. - Нет, существует. Я видел его в Интернете.

Впервые за целую вечность он почувствовал, что глаза его застилают слезы, и зажмурился, прогоняя влажную пелену. Он знал, что для эмоций еще будет время, а теперь пора отправляться домой. Он попробовал встать, но настолько выбился из сил, что не смог ступить ни шагу и долго сидел, изможденный вконец, на каменных ступеньках, рассеянно разглядывая распростертое у его ног тело. Глаза Халохота закатились, глядя в пустоту.

Он даже представить себе не может, насколько хуже. Не в силах сдержать нетерпение, Беккер попытался позвонить снова, но по-прежнему безрезультатно. Больше ждать он не мог: глаза горели огнем, нужно было промыть их водой. Стратмор подождет минуту-другую.

PDF | This paper describes an optimal vehicle speed controller that uses speed in m/s, i is the transmission ratio and f is the rolling.
