Recuperation is one of the main methods for reducing energy consumption in hybrid and electric vehicles. Recuperation is the conversion of the kinetic energy of the vehicle into electric energy when the vehicle is decelerating. This energy may be stored in the traction battery and used afterwards for driving the vehicle. During recuperation the electric motor of the drivetrain works as a generator inducing a recuperation torque, which is transmitted to the wheels by the drivetrain. The resulting wheel forces decelerate the vehicle and influence its dynamic behaviour. From the chassis and brakes perspective, the recuperating drivetrain represents a second source of braking torque, which decelerates the vehicle and influences the driving dynamics. The recuperation function incorporates both braking and drive functions, and is of relevance for safety. This places great demands on both the functional and safety concept as well as on the development-related processes or the interdepartmental development activities. The intelligent integration of the recuperation function into the braking control system, in conjunction with its integration with the drivetrain and the use of suitable blending-capable braking systems, leads to maximum recuperation performance while at the same time guaranteeing driving safety, brake-pedal feel and comfort.
