  • Publication number: 20220274597
    Abstract: A method is for controlling a system for regulating a distance between a target vehicle and a following vehicle, with the regulation system being installed on the following vehicle. The method includes the implementation of a control law for regulating the distance which calculates, for a plurality of possible combinations of speeds of movement of the following vehicle and the target vehicle, potential setpoint distances, and, for a given combination of speeds of movement of the following and target vehicles, from the plurality of possible combinations, the determination of a final setpoint distance among the potential setpoint distances previously calculated by the control law.

  • Patent number: 8589046
    Abstract: A method of releasing brakes of a motor vehicle including: if no vehicle start command takes place, after manual application of the vehicle brakes in a position to immobilize the vehicle when at rest is over, an assistance device progressively releases the brakes according to a suitable control scheme configured to make the vehicle move under its own weight, generally tending towards predetermined non-zero speed and acceleration conditions, and then, when the predetermined conditions are considered to have been reached, the assistance device stops releasing the brakes.

  • Patent number: 8521387
    Abstract: A method for assisting a motor vehicle with a hill start, the motor vehicle having previously been held stationary when parked by a brake. The method measures inclination of the vehicle, previously establishes a map between engine torque and engine speed, defines, within the map, an authorized zone and a forbidden zone, provides a vehicle engine speed value, provides a vehicle engine torque value, deduces from these coordinates of the engine operating point within the map, and releases the brake automatically only if the coordinates of the operating point lie within the authorized zone of the map.

  • Publication number: 20100211280
    Abstract: A regenerative braking control method for a hybrid vehicle and an arrangement for a vehicle using the method, whereby the vehicle is provided with an electric machine coupled to the rear wheels of the vehicle by a coupling mechanism and which includes a controller for powering and/or electrically charging an associated battery, the controller being controlled during a regenerative braking mode by a distribution controller implementing the method.
