  • Publication number: 20230400313
    Abstract: A method to calculate a driving route includes the steps of acquiring information corresponding to a departure place of the motor vehicle and to a target destination, determining a road map comprising a departure point and an arrival point of the driving route associated with the departure place and with the destination, respectively, calculating the driving route on the road map from the departure point to the arrival point by solving a path planning problem comprising an optimization of a target function depending on at least one first scalar parameter defined by a fun index, wherein the fun index is indicative of a level of fun of the driving route and wherein the target function strays away from an optimum value thereof when the fun index indicates a deviation of the level of fun from a target level or a decrease in the level of fun, the optimum value of the target function corresponding to the solution of the path planning problem.

  • Publication number: 20230331055
    Abstract: A method to control an active shock absorber of a road vehicle. The active shock absorber is part of a suspension connecting a frame of the road vehicle to a hub of a wheel and has: a first element, which defines an end of the active shock absorber, a second element, which defines another end of the active shock absorber and is mounted so as to slide relative to the first element; and an actuator, which is configured to generate a force, which is applied between the two elements. The control method comprises the steps of: determining a vertical acceleration of the hub; determining a speed of translation between the two elements of the active shock absorber; determining a target force for the actuator of the active shock absorber based on the vertical acceleration of the hub and based on the speed of translation between the two elements of the active shock absorber; and controlling the actuator (10) of the active shock absorber so as to pursue the target force.

  • Patent number: 11628826
    Abstract: A method to control, while driving along a curve, a road vehicle with a variable stiffness and with rear steering wheels. The method comprises the steps of: determining an actual attitude angle of the road vehicle; establishing a desired attitude angle; determining an actual yaw rate of the road vehicle; establishing a desired yaw rate; and changing, in a simultaneous and coordinated manner, the steering angle of the rear wheels and the distribution of the stiffness of the connection of the four wheels to the frame depending on a difference between the actual attitude angle and the desired attitude angle and depending on a difference between the actual yaw rate and the desired yaw rate.

  • Publication number: 20220402372
    Abstract: A process to control a drive assembly includes the steps of providing a mathematical model associating a first quantity indicative of a torque delivered by a motor-generator with a second quantity indicative of a linear acceleration of a wheel hub unit, which receives the torque, acquiring a first signal indicative of the second quantity, determining a target signal of the first quantity by means of the mathematical model based on the acquired first signal, so that the torque indicated by the target signal involves at least a decrease in a difference between the second quantity and a reference, and controlling the motor-generator according to the determined target signal.
