  • Patent number: 11467617
    Abstract: A cable-linked brake pedal assembly for an airplane. The assembly includes a first cable assembly with a first end attached to a pilot-side brake pedal and a second end attached to a first bell crank assembly, and a second cable assembly with a first end attached to a copilot-side brake pedal and a second end attached to a second bell crank assembly. A first connecting rod with a first rod end is attached to the first bell crank assembly and a second rod end is attached to the second bell crank assembly. The connection between the first and second cable assemblies, first and second bell crank assemblies, and first connecting rod is configured such that depressing the pilot-side brake pedal moves the first cable assembly, first connecting rod, and second cable assembly in such a way as to cause a corresponding depression of the copilot-side brake pedal.

  • Patent number: 11458940
    Abstract: A brake ECU sets target slippage degrees of three wheels other than the front outer wheel to the slippage degree of the front outer wheel and feedback-controls the braking forces of the three wheels such that the actual slippage degrees of the three wheels approach the target slippage degrees. The brake ECU computes a correction amount for the slip ratio deviation of the front inner wheel such that the slip ratio deviation becomes zero. The brake ECU multiplies the correction amount for the slip ratio deviation by a load ratio and uses the resultant value as a correction amount for the slip ratio deviation of the rear inner wheel. The brake ECU corrects the slip ratio deviation by using the computed correction amount.

  • Patent number: 11441677
    Abstract: The invention relates to a control arrangement for vehicles having a hydrostatic auxiliary drive for one or more axles, in particular for motor graders, having a drive engine, driven rear wheels coupled to the drive engine, further wheels which can be activated by associated hydraulic motors and can be operated by a hydraulic pump coupled to the drive engine and which has an adjustable feed volume, wherein each wheel is connected to a hydraulic motor without a clutch. The hydraulic pump and the hydraulic motors can be activated electrically and adjusted in a continuously variable fashion and the hydraulic pump is connected directly, without valves, to the hydraulic motors in parallel by hydraulic lines. The control device controls the respective displacement volume of the hydraulic motors only as a function of the rotational speed signals of the sensors.

  • Patent number: 11427167
    Abstract: A method for performing emergency braking in a vehicle includes registering at least one object in surroundings of the vehicle and ascertaining a probability of collision for the vehicle with the at least one registered object to detect an emergency braking situation, autonomously activating service brakes of the vehicle using a vehicle setpoint deceleration to perform emergency braking if an emergency braking situation has been detected, and adapting the vehicle setpoint deceleration during the autonomously performed emergency braking. Adapting the vehicle setpoint deceleration takes place in dependence on at least one driving dynamics parameter. The driving dynamics parameter characterizes a real reaction of the vehicle to the performed emergency braking. The driving dynamics parameter is ascertained during the emergency braking.

  • Patent number: 11409278
    Abstract: The present disclosure is directed to systems and techniques for providing a teleoperation instruction to an autonomous vehicle. While the autonomous vehicle is travelling to a destination, the autonomous vehicle may encounter a situation preventing the autonomous vehicle from travelling to the destination. A control center may receive information from the autonomous device and provide instructions with limited controls for the autonomous vehicle to navigate to an intermediate position. In such an intermediate position, the may make way for an emergency vehicle, obtain additional sensor data for continued autonomous planning, signal intent to other objects in the environment, and the like.

  • Patent number: 11401876
    Abstract: A control system for a vehicle is provided, which includes a driving force source configured to generate torque for driving drive wheels, a steering angle related value sensor configured to detect a steering angle related value of a steering device of the vehicle, a grille shutter configured to adjust an opening-and-closing degree of an opening formed in a front surface of a vehicle body, and a controller configured to control the torque to control a vehicle attitude based on the steering angle related value. Based on the steering angle related value, when the controller determines that a turning operation of the steering device is performed, it performs a torque decreasing control for reducing the torque to add deceleration to the vehicle, and when the grille shutter opening is large, the controller increases the torque reduction amount in the torque decreasing control more than when the opening is small.

  • Patent number: 11380194
    Abstract: To control vehicular congestion at intersections, a method includes detecting a group of two or more vehicles stopped at an intersection regulated by a traffic light, where for each of the vehicles in the group, movement through the intersection in response to a change in a state of the traffic light is affected by movement of at least one other vehicle in the group. The method further includes determining a time when the state of the traffic light changes to allow the group of vehicles to start moving through the intersection, determining acceleration parameters for a certain vehicle in the group in view of potential and/or actual movement of the other vehicles in the group through the intersection, and providing guidance to a device operated by a driver of the certain vehicle regarding the determined acceleration parameters, in accordance with the determined time.
