Target Engine Speed

The target engine speed is critical in deciding the position of the ratio control motor. The EMS 2000 will keep changing the ratio of the motor to achieve the target engine speed. The target engine speed is mapped inside the EMS 2000 against Road speed and Driver demand (throttle angle).

The map is not linear. To achieve good driving characteristics the engine target speed map is programmed to overcome.

• The initial engine speed required to build pressure within the hydraulic clutch.
• The hydraulic profile of the transmission itself.
• The engines power and torque profile.

When the transmission is operating in the D mode (drive), the driver does not experience full engine power until the road speed reaches 50 mph.
