  • Patent number: 11326664
    Abstract: A method for reshaping an electric drive signal of a real-time damper in a sprung mass system includes detecting a periodic frequency and magnitude of a target periodic vibration of a sprung mass. The periodic vibration has velocity and elasticity components that are 90 degrees out-of-phase. An electric drive signal to the real-time damper is reshaped by a controller depending on polarity of the velocity component to thereby generate a composite drive signal. The damper is energized using the composite drive signal to modify a damper force. Reshaping the electric drive signal includes injecting a force and/or an intermittent drive suppression component onto the electric drive signal based on the frequency and magnitude. The sprung mass system may have a frame and body, motion and wheel speed sensors, the real-time dampers, road wheels, and a controller programmed to perform the method.

  • Patent number: 11320273
    Abstract: A system accesses a three-dimensional map of a geographic region and generates a two-dimensional projection of the road based on the three-dimensional map. The two-dimensional projection comprises a plurality of points along the road and each point is assigned a score measuring a navigability of the point. Based on the navigability score of each point and history of vehicle positions on the road, the system identifies a plurality of navigable points on the two-dimensional projection of the road. Based on the plurality of navigable points, the system determines a navigable surface corresponding to a physical area over which a vehicle may safely navigate and navigable surface boundaries surrounding that area. The navigable surface area and boundaries on the two-dimensional projection are converted into a three-dimensional representation, which the system uses to generate an updated three-dimensional map of the geographic region.

The controller adjusts the biometric monitor according to the adjustment such that the biometric monitor is adjusted in monitoring the occupant according to the adjustment as the vehicle drives over the upcoming road segment. The controller may determine an adaptation to a suspension assembly of the vehicle for the suspension assembly to counteract the expected effect and adapt the suspension assembly according to the adaptation. The adjustment to the biometric monitor is modified accordingly.

  • Patent number: 10976210
    Abstract: The invention concerns a method for estimating an external force acting on an electrohydrostatic actuator, the actuator comprising a ram including a first chamber, a second chamber and a piston located between the first chamber and the second chamber, a pump capable of injecting fluid into the chambers for controlling a movement of the piston, and an electric motor driving the pump, the method comprising steps of: estimating, by means of at least one state observer (21, 22), a dynamic component and a static component of a difference in equivalent fluid pressure between the first chamber and the second chamber from a rotational speed of the electric motor, a position of the piston and a supply current of the electric motor, estimating the external force by means of a post-processing module (23) as a combination of the estimated dynamic component and static component of the difference in fluid pressure.

  • Patent number: 10967861
    Abstract: Aspects of the disclosure relate to controlling a first vehicle in an autonomous driving mode. While doing so, a second vehicle may be identified. This vehicle may be determined to be a tailgating vehicle. An initial allowable discomfort value representing expected discomfort of an occupant of the first vehicle and expected discomfort of an occupant of the second vehicle may be identified. Determining a speed profile for a future trajectory of the first vehicle that meets the value may be attempted based on a set of factors corresponding to a reaction of the tailgating vehicle. When a speed profile that meets the value cannot be determined, the value may be adjusted until a speed profile that meets the value is determined. The speed profile that meets an adjusted value is used to control the first vehicle in the autonomous driving mode.

  • Patent number: 10967946
    Abstract: A system comprises an elastic mount configured to support a propulsion device with respect to a marine vessel. The elastic mount contains an electromagnetic fluid. An electromagnet is configured so that increasing an amount of electricity applied to the electromagnet increases the shear strength of the electromagnetic fluid in the elastic mount and thereby decreases elasticity of the elastic mount, and so that decreasing the amount of electricity applied to the electromagnet decreases the shear strength of the electromagnetic fluid in the elastic mount and thereby increases the elasticity of the elastic mount. A controller automatically adapts the amount of electricity applied to the electromagnet based on one or more sensed conditions so as to improve performance and/or handling of the marine vessel.

  • Patent number: 10926723
    Abstract: A system and method performed by a sensor testing apparatus of a vehicle are provided for determining when certain event conditions are true. The event conditions comprise detecting an occurrence of a predefined event that impacts a sensor of the vehicle. After the predefined event is detected, a test is performed to determine whether the sensor is outputting sensor values within sensor specification values. When the event conditions are true, the method includes testing the sensor relative to a reference to determine when the sensor is operating within reference criteria to produce a positive reference testing result. When the reference testing result is positive, the method directs the vehicle to return to normal operation, and otherwise directs the vehicle to be serviced.
