Patents by Inventor Remy Delplace

Remy Delplace has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8311692
    Abstract: The invention relates to a braking method for a hybrid vehicle (1) comprising a drivetrain (3) controlled by a drivetrain computer (12), and a hydraulic braking system (15) controlled by a braking computer (21). In this method, as soon as the drivetrain computer (12) detects that the electrical braking torque is decreasing, this drivetrain computer (12) informs the hydraulic braking computer (21) of the value of the reduction in electric braking torque. The braking computer (21) then operates the hydraulic braking system (15) in such a way that the hydraulic braking torque applied to the wheels (2) by the brakes (17) compensates for this reduction in electric braking torque.

  • Patent number: 7720588
    Abstract: A process for assisting the driving of a vehicle provided with a braking system including brake calipers able to be activated as a function of a target braking force, including the steps of: determining an instantaneous state of the vehicle defined by state variables measured by sensors with which the vehicle is provided; testing a logical entry condition verified when the velocity of the vehicle is zero and when the slope is greater than a pre-defined slope; when the logical entry condition is verified, testing a logical exit condition; automatically operating the braking system to keep the vehicle static on the slope while the logical exit condition is not verified; and automatically releasing the activation of the braking system when the logical exit condition is verified.

  • Publication number: 20100106386
    Abstract: The invention relates to a method for braking a hybrid vehicle (1) including a thermal engine and an electric machine (3) defining a traction chain. According to this method, when the depression of the brake pedal is detected, an additional electric braking torque is added (Cf_recup), and the additional electric braking torque is modulated according to the position of the brake pedal as measured by a pedal stroke sensor (42) and/or to the braking hydraulic pressure as measured by a braking pressure sensor (43).

  • Patent number: 6272419
    Abstract: This method for controlling the behaviour of an automotive vehicle during cornering consisting in measuring the rotational wheel speed of the front and rear wheels of the vehicle, establishing the wheel speed difference between the front and rear wheels and modifying the brake pressure applied to the rear wheel brakes of the vehicle according to a vehicle behaviour to be obtained, comprises the steps of elaborating a function of the absolute value of the wheel speed difference between the inner front wheel and the outer rear wheel, considering the cornering direction and using said function to determine the brake pressure variations to be applied to the rear wheel brakes.
