A method that calculates a setpoint for managing the fuel and electricity consumption of a hybrid motor vehicle includes: a) acquiring, by a navigation system on board the hybrid motor vehicle, a route to be traveled; b) dividing the route into consecutive portions; c) assigning attributes that characterize each portion; d) determining, for each of the portions, a curve or a map that links each fuel consumption value of the hybrid motor vehicle over the portion to a charge or discharge value of the traction battery; e) determining an optimal point of each curve or map, which makes it possible to minimize the fuel consumption of the hybrid motor vehicle over the entire route and to completely discharge the traction battery by the end of the route; and f) producing an energy management setpoint in accordance with the coordinates of the optimal points.

A first method for estimating a torque/force exerted by a load against an actuator driven by an electric motor against the load includes measuring motor current of the electric motor and measuring a position/angle or speed/angular speed of the actuator and includes calculating the torque/force exerted by the load against the actuator using at least a difference between a calculated motor torque/force and a calculated actuator-experienced torque/force. A second method includes measuring input voltage of the electric motor instead of measuring motor current. A third method includes measuring both motor current and input voltage. In one example, without limitation, the actuator is an automotive electromechanical brake caliper.
