  • Patent number: 10807579
    Abstract: Apparatus and associated methods relate to controlling a brake mechanism during braking operation to provide near-maximal braking power. Maximal braking power occurs at when the wheel slip has a target value. Wheel slip can be monitored during braking operation so as to be used in control the brake mechanism to operate at the maximal braking power. The braking power is modulated so as to dither the braking power about a nominal braking power. The monitored wheel slip will have a dither component in response to the dithering of the braking power. A volatility of the dither component of the monitored wheel slip can be indicative of nominal braking power proximity to the maximal braking power. A nominal brake signal can be generated so as to change the nominal braking power in the direction of the maximal braking power based on the volatility of the dither component of the monitored wheel slip.

  • Patent number: 10562512
    Abstract: Methods and systems are provided for adjusting clutch pressures and electric machine torques as a function of a stability metric threshold(s) in order to balance performance and charging of an onboard energy storage device. In one example, a method includes during an upshift of a transmission from a first gear to a second gear, adjusting a clutch pressure of the transmission to adjust slippage of a clutch in response to a vehicle stability control parameter exceeding a threshold. In this way, torque delivered to a transmission output shaft may be reduced, which may increase vehicle stability.

  • Patent number: 10532768
    Abstract: The present invention relates to a method for controlling the position of a vehicle to ensure stable position of a vehicle against tilting due to a rapid change in vehicle speed. The method includes: determining whether a vehicle speed is rapidly changing in a straight direction on the basis of an extent of depression of a pedal that changes a position of a steering wheel and a change in vehicle speed; determining whether the vehicle is tilting on the basis of a change in a yaw-rate by means of the controller when the vehicle speed is rapidly changing in the straight direction; and providing compensation torque in the direction opposite the direction in which the vehicle is tilted by operating a steering motor when the controller determines that the vehicle is tilting.

  • Patent number: 10526981
    Abstract: An engine control device is provided, that includes an air amount controller, an ignition timing controller, a basic target torque determinator which determines a basic target torque, a change rate acquirer for acquiring a change rate of a steering operation, a target additional deceleration setter for increasing a target additional deceleration while an increase rate thereof becomes less as the change rate increases, a torque reduction amount determinator for determining an engine torque reduction amount, a final target torque determinator for determining a final target torque, and an actual air amount estimator for estimating an actual air amount introduced into a combustion chamber. The air amount controller determines a target air amount and controls the intake air amount to achieve the target air amount. The ignition timing controller retards the ignition timing more as the actual air amount becomes more excessive with respect to the target amount.

  • Patent number: 10518781
    Abstract: Powertrains may include a spring damper between the engine crankshaft and transmission input shaft. In some circumstances, an oscillation known as shuffle may occur in such powertrains. Active adjustment of engine torque is substantially more effective at mitigating shuffle oscillations if the engine torque includes a p-term proportional to displacement of the damper spring in addition to a d-term proportional to the speed difference across the damper. For various reasons, the spring displacement is difficult to measure directly. An observer algorithm is utilized to calculate a current estimated spring displacement based on a crankshaft speed sensor, a transmission input speed sensor, a wheel speed sensor, and past engine torques, using a dynamic model of the powertrain.

  • Patent number: 10518808
    Abstract: A method for influencing the direction of travel of motor vehicles. The motor vehicle has a first steering system, having at least one steering axle with at least two wheels. The wheels are connected to the steering axle through wheel suspensions that can be adjusted by actuators. A redundant steering system is realized by adjusting a steering roll radius of at least one of the steering axles, according to which a force component acting orthogonally to the direction of travel in the region of at least one wheel is applied to the first steering system.

  • Patent number: 10518765
    Abstract: A stability control system for a vehicle that has an electric traction motor that provides torque to an axle through a differential. The traction motor responds to an instability event that is sensed by sensors on the vehicle by initially reducing the torque provided to the traction wheels to regain steering control. The traction motor then pulses increased torque in sequence with the application of braking force to provide enhanced direct yaw moment control.

  • Patent number: 10494789
    Abstract: An electronic control system for a work allows for control of steering despite movement of an implement that may support a load. Control may be based on vehicle position, velocity, acceleration, center of gravity, and heading. A control point is determined despite movement of the load, and may be based upon one or more of roll, yaw, and pitch of the vehicle. The vehicle may be of the type that allows for control only of wheel or track speed and rotational direction. A desired center of gravity is maintained while controlling an error between a desired vehicle trajectory and a determined trajectory in a closed loop manner.
