How does a hybrid engine controller regulate power and calculate mileage?

[varun]

I'm working on a hybrid engine project but its hard to find any info on the controller... does anyone know what are the common inputs/outputs and does the conroller itself regulate the power source (engine/motor) or is there a separate system to do this?

Another thing what is the best way to calculate engine mileage?.

When you mention controller, are you reffering to the power supply, or something that would effectively be your gas pedal?

If your using a dc motor, the power supply should be rather simple, and you can use something like a potentiometer (spelling?) to throttle the motor.

Perhaps a bit more info on the components your using?

A hybrid engine controller is a crucial component in regulating power and calculating mileage in a hybrid vehicle. It is responsible for controlling the flow of energy between the engine and the electric motor, as well as managing the battery charging and discharging process.

The controller receives inputs from various sensors such as the throttle position, vehicle speed, battery state of charge, and engine speed. These inputs are used to determine the most efficient way to distribute power between the engine and motor, depending on the driving conditions. For example, during acceleration, the controller may use both the engine and electric motor to provide maximum power. On the other hand, during deceleration or braking, the controller can use regenerative braking to recharge the battery.

In terms of regulating the power source, the hybrid engine controller is responsible for starting and stopping the engine, as well as controlling the electric motor. It also monitors the state of charge of the battery and manages the charging process to ensure optimal performance and longevity of the battery.

As for calculating engine mileage, there are various methods used by different manufacturers. Some may use a simple calculation based on the amount of fuel consumed, while others may use more advanced algorithms that take into account driving conditions and energy usage. Generally, the controller will keep track of the amount of energy used from both the engine and the battery and use that data to calculate the overall fuel efficiency of the vehicle.

In terms of inputs and outputs, the specific details may vary depending on the manufacturer and the type of hybrid system. However, some common inputs and outputs of a hybrid engine controller include battery voltage, current, and temperature, engine speed, vehicle speed, throttle position, and brake position. Outputs may include control signals for the engine, electric motor, and battery charging system.

Overall, the hybrid engine controller plays a crucial role in ensuring the efficiency and performance of a hybrid vehicle. Its ability to regulate power and calculate mileage is essential in achieving maximum fuel efficiency and reducing emissions.
