  • Method of controlling a hybrid vehicle during regenerative deceleration
    Patent number: 8292777
    Abstract: A method of controlling a hybrid vehicle during regenerative deceleration, the method including: determining deceleration of the vehicle; upon determining deceleration of the vehicle, operating a reversible electric machine as a generator to regenerate part of the kinetic energy of the vehicle; establishing a respective minimum speed of an internal combustion engine for each gear of a servocontrolled mechanical power train; determining and engaging the highest gear which, combined with the current state of motion of the vehicle, runs the internal combustion engine at higher than the respective minimum speed; keeping the gear engaged as long as the internal combustion engine runs at higher than the respective minimum speed; and downshifting by one gear when the internal combustion engine runs at lower than the respective minimum speed.

  • ROAD VEHICLE CONTROL METHOD
    Publication number: 20090143961
    Abstract: A control method of a road vehicle; the control method includes the steps of: detecting the position of an accelerator control which is displaced along a predetermined stroke; using the position of the accelerator control to control the generation of a torque generated by the engine of the road vehicle so that the torque is generated according to the position of the accelerator control; detecting the current driver's ability by means of a driving ability recognition device; and limiting the generation of torque according to the current driver's ability.
