Abstract

A series hybrid vehicle comprising an engine driving an alternator, the engine having a power available at the output shaft of the engine, at least one electric traction motor connected to the alternator by an electric line and an inverter, the inverter allowing the electric traction motor to be operated at a desired torque, the electric line allowing the transfer of an electric traction power, an accelerator control CA at the disposal of the vehicle driver, an actuator acting on the engine, a control device controlling the position of the actuator as a function of the position of the accelerator control, as far as a limitation at least when the desired torque reaches the maximum torque of the electric traction motor, a unit for controlling the propulsion torque of the vehicle, allowing the desired torque to be continuously calculated, in accordance with a chosen sampling period, as a function of the vehicle speed and as a function of a control power P evaluating the power available at the output shaft of the engine as a function of the actual speed of the engine.
