    Abstract: A method for predicting a future action of agents in a scene includes assigning a fidelity level to agents observed in the scene. The method also includes recursively predicting future actions of the agents by traversing the scene. A different forward prediction model is used at each recursion level. The method further includes controlling an action of an ego agent based on the predicted future actions of the agents.

  • Patent number: 11244179
    Abstract: A stop line position estimation device includes a traffic signal recognition unit configured to recognize a traffic signal at an intersection ahead of a vehicle and a stop line position estimation unit configured to estimate that a position of the stop line is a position from the traffic signal by a first distance toward the vehicle side. When the traffic signal recognition unit recognizes a plurality of traffic signals and the stop line position estimation unit recognizes an immediate front traffic signal and a rear traffic signal based on a positional relationship between the traffic signals, the stop line position estimation unit estimates that the position of the stop line is a position from the immediate front traffic signal by a second distance toward the vehicle side. The second distance is shorter than the first distance.

  • Patent number: 11242042
    Abstract: A control system and method control release of a braking device from a wheel or disc. Release of the braking device is slowed or stopped based on a speed at which the braking device is released. The braking device may include a return limiting device through which a rod is configured to move. The return limiting device permits the rod to slide within the return limiting device while the brake pad holder releases from the wheel or disc no faster than a designated speed, but engages and restricts movement of the rod within the return limiting device while the brake pad holder releases from the wheel or disc faster than the designated speed.

  • Patent number: 11241955
    Abstract: The present disclosure relates to a powertrain controller (3) for controlling a torque distribution between a front axle (4) and a rear axle (5) of a vehicle (1). The powertrain controller (3) includes a processor (8) and a memory device (9). The processor (8) is configured selectively to implement first and second torque distribution profiles (TDP1, TDP2) defining the torque distribution between the front axle (4) and the rear axle (5). The processor (8) determines when one or more vehicle dynamics parameter (VDPn) is within one or more predefined stability margin (VSMn) and when the one or more vehicle dynamics parameter (VDPn) is outside the one or more predefined stability margin (VSMn). A torque request signal (STQR) is monitored to identify a change in a torque request (TQR). The first torque distribution profile (TDP1) is implemented when the one or more vehicle dynamics parameter (VDPn) is within the one or more predefined stability margin (VSMn).

  • Patent number: 11203354
    Abstract: A system for controlling a vehicle by jointly estimating a state of a vehicle and a function of a tire friction of a vehicle traveling on a road uses a particle filter maintaining a set of particles. Each particle includes an estimation of a state of the vehicle, an estimation of probability density function (pdf) of the tire friction function, and a weight indicative of a probability of the particle. The system executes the particle filter to update the particles based on a motion model and a measurement model of the vehicle, control commands moving the vehicle and measurements of the state where the vehicle moved according to the control commands. A control command is generated based on the motion of the vehicle, the weighted combinations of the state of the vehicle and the pdf of the tire friction function weighted according corresponding weights of the particles.
