Abstract
A method and system of accelerating a vehicle from an intermediate speed to a target speed under control of a cruise control or driving speed control unit are disclosed. An acceleration rate of a vehicle is measured while a vehicle speed is below an intermediate speed at which the driving speed control unit is enabled. The intermediate speed is greater than the initial speed and less than the target speed. A derived acceleration rate is calculated using the measured acceleration rate. When the driving speed control unit is enabled, the vehicle is accelerated from the intermediate speed to the final speed at an acceleration rate about equal to the derived acceleration rate. The derived acceleration rate may be the acceleration rate of the vehicle at the intermediate speed, the average acceleration rate between the initial and intermediate speeds, or the average acceleration rate within a threshold of the intermediate speed.
