  • Publication number: 20220306149
    Abstract: A control device is for controlling an autonomous motor vehicle in order to modify a steering angle of a steered wheel of the autonomous motor vehicle and/or a braking force generated by the brake fitted to a wheel of the autonomous motor vehicle. The control device includes an automatic piloting system, which is configured to generate an automatic driving instruction for automatically driving the vehicle, a primary command chain, which includes a primary controller configured to generate a primary command according to the automatic driving instruction, and at least one primary actuator configured to generate a torque that confers a steering angle to the steered wheel, or configured to actuate the brake based on the primary command obtained directly from the primary controller. A secondary command chain is also included.

  • Publication number: 20220234552
    Abstract: Control equipment is capable of controlling braking of an autonomous motor vehicle that includes at least one wheel. The control equipment includes a braking system, which includes at least a hydraulic circuit and a brake able to apply a braking force on the wheel as a function of a hydraulic pressure present in the hydraulic circuit. The control equipment also includes a primary controller configured to determine a braking setpoint, a primary actuator able to generate hydraulic pressure as a function of the braking setpoint when the primary actuator receives the braking setpoint, an external sensor configured to transmit an external measurement signal to the primary controller, and an auxiliary actuator able to generate the hydraulic pressure as a substitute for the primary actuator.

  • Publication number: 20220234652
    Abstract: Control equipment is capable of controlling a steering angle of an autonomous motor vehicle that has at least one steered wheel. The control equipment includes a primary controller configured to determine a steering setpoint; and a primary actuator configured to impart a steering angle to the steered wheel of the vehicle in accordance with the steering setpoint when the primary actuator receives the steering setpoint. The primary actuator includes an internal sensor configured to transmit to the primary controller an internal measurement signal corresponding to a measurement of the steering angle imparted by the primary actuator. The control equipment also includes an external sensor; and an auxiliary actuator configured to impart a steering angle to the steered wheel of the vehicle when the auxiliary actuator receives the steering setpoint.

  • Patent number: 7826940
    Abstract: The invention essentially concerns a method for fast starting on an up slope or with a high load. Said method uses a power transmission device (1.1) comprising a traction chain. Said traction chain consists in particular of a heat engine (2), a clutch (3), an electrical macine (4), and wheels (6). The invention is characterized in that while the vehicle is stopped or is running at low speed up a slope, the heat engine (2) is stopped, and when the vehicle is accelerated, the heat engine (2) is started using a starting system (7) mechanically independent of the electrical machine.

  • Patent number: 7766108
    Abstract: The invention essentially concerns a method for fast starting of a hybrid vehicle. Said method uses a power transmission device (1.1) comprising a traction chain consisting of a heat engine (2), a clutch (3), an electrical machine (4), and wheels (6). The invention is characterized in that said method, in order to rapidly accelerate the vehicle when it is stopped, consists in starting the heat engine (2) concurrently with the actuation of the electrical machine, using a starting system (7) mechanically independent of the electrical machine (4).

  • Publication number: 20060019040
    Abstract: Patente of invention for “Hydrogen Diffusion Barrier on Steel by Means of a Pulsed-Plasmalon-Nitriding Process”. The present invention refers to a pulsed-plasma ion-nitriding process performed with the objective of creating hydrogen diffusion barrier on steel, herein exemplified by using the API 5L X-65 steel; high-strength low-alloy steel. The pulsed-plasma ion-nitriding consisted to drive ions and active species of atomic and molecular nitrogen to the material's surface by applying a difference of potential between two electrodes, periodically interrupted with a pre-determined frequency, such that the cathode (1) is the own material or piece to be treated, in a chamber (2) that was previously vacuum pumped (4) and then filled up (6) with the gas nitrogen or a gaseous mixture containing this gas.
