SYSTEM AND METHOD FOR OPTIMIZING REGENERATIVE BRAKING IN ADAPTIVE CRUISE CONTROL

摘要

A vehicle includes traction wheels, an electric machine configured to provide regenerative braking torque to the traction wheels, wheel brakes configured to provide friction braking torque to the traction wheels, and at least one power source configured to provide drive torque to the traction wheels. The vehicle additionally includes, a sensor configured to detect a forward object, and at least one controller. The controller is configured to control the power source, wheel brakes, and electric machine according to an adaptive cruise control (ACC) algorithm. The ACC algorithm is configured to command the electric machine to provide regenerative braking torque without application of the wheel brakes in response to a detected forward object and a maximum regeneration braking distance. The maximum regeneration braking distance is calculated based on a powertrain regenerative braking limit and a distance to the forward object.
