  • Patent number: 11964644
    Abstract: A method for operating a motor vehicle brake system having hydraulic wheel brakes; an atmospheric pressure pressure medium reservoir; a pressure modulation unit setting wheel-specific brake pressures, an electrohydraulic pressure provision device connected to the pressure modulation unit and the pressure medium reservoir which outputs brake system pressure to the pressure modulation unit and draws in pressure medium from the reservoir; a first and second pressure activation valve connecting the pressure provision device to the pressure modulation device. A piston of the piston-cylinder arrangement separates two pressure spaces from one another. A pressure build-up occurs in the first pressure space during a backward movement of the piston and in the second pressure space during a forward movement of the piston. During a brake pressure build-up by a forward stroke of the piston, the activation valve is opened and the first pressure space is hydraulically separated from the pressure medium reservoir.

  • Patent number: 11951979
    Abstract: Disclosed are systems and methods for autonomous vehicles and vehicles with automatic driver-assistance systems (ADAS) to automatically detect an imminent collision, determine whether the collision is avoidable or unavoidable, and plot a course minimizing the hazard using an artificial intelligence (AI) model. For example, a collision is avoidable if the vehicle can avoid it by steering, braking, and/or accelerating in a particular sequence. The AI model finds the best sequence for collision avoidance, and if that is not possible, it finds the best sequence for minimizing the harm. The harm is based on an estimated number of fatalities, injuries, and property damage predicted to be caused in the collision. The AI-based situation analysis and sequence selection are directly applicable to human-driven vehicles with an emergency-intervention ADAS system, as well as fully autonomous vehicles. With fast electronic reflexes and multi-sensor situation awareness, the AI model can save lives on the highway.

  • Patent number: 11820255
    Abstract: Systems and methods are directed to dynamically and automatically adjusting a standard regenerative braking intensity. Roadway data, data from one or more sensors of a vehicle and data including parameter values for operating states of the vehicle regarding a roadway from a route being navigated by the vehicle are received by a processor of a control system of the vehicle. Standard regenerative braking intensity values based on a vehicle's acceleration is retrieved from memory. Adjusted regenerative braking intensity values are calculated based on at least one of the roadway data, the sensor data and the parameter values of the operating states of the vehicle and the standard regenerative braking intensity values. The adjusted regenerative braking intensity values are transmitted to the control system and an acceleration or deacceleration amount is applied to the vehicle based on the adjusted regenerative braking intensity values.

  • Patent number: 11820377
    Abstract: A number of illustrative variations may include a system including brake-to-steer algorithms may achieve lateral control of a vehicle without longitudinal compensation but may also force a vehicle to slow down too rapidly before appropriate lateral movement can be achieved and may deliver an unnatural driving experience for vehicle occupants. A more natural feeling deceleration may be achieved by optimally selecting appropriate transmission shifts to allow for optimal engine speed or electric motor speed and torque based on current vehicle speed thereby reducing undesirably longitudinal disturbance.

  • Patent number: 11814055
    Abstract: A system for determining vehicle direction includes an active wheel speed sensor (aWSS), an exciter ring for inducing a change in a signal from the aWSS and a controller. The controller receives a first series of signals from the aWSS, compares them to an array of predefined signals and determines the direction of travel based on the first series of signals matching the array. The controller receives a second series of signals and determines the exciter ring has an anomaly in response to at least one signal in the second series of signals having a first variance. The controller updates the array of predefined signals to include a representation of the first variance to create an array of updated signals. The controller determines the direction of travel based on a subsequent series of signals matching one of the array of predefined signals and the array of updated signals.

  • Patent number: 11807060
    Abstract: A vehicle height adjusting device includes a vehicle height adjusting unit, a prediction unit, and a vehicle height control unit. The vehicle height adjusting unit adjusts a vehicle height to one of a first state and a second state. In the first state, the vehicle height is set to a predetermined height, and in the second state, the vehicle height is set lower than the first state. The prediction unit predicts whether a drive battery (lower portion) of a vehicle interferes with a road surface in the second state. The vehicle height control unit controls the vehicle height adjusting unit to set the vehicle height to one of the first state and the second state. When the prediction unit predicts an interference between the drive battery of the vehicle and the road surface, the vehicle height adjusting unit restricts a transition from the first state to the second state.

  • Patent number: 11780425
    Abstract: The vehicle control apparatus comprises a sensor to detect a turning movement physical quantity, an acceleration-deceleration device, a control unit, and a device to obtain road shape information representing a shape of a road at a position that is away from a vehicle by a predetermined distance. The unit determines that a first control start condition becomes satisfied when a magnitude of the physical quantity exceeds a first value while the curved road has not been determined to be present based on the road shape information, to perform an acceleration-deceleration control for making the vehicle run at a target speed depending on a curvature of the road. The unit determines that a second control start condition becomes satisfied when the magnitude of the physical quantity exceeds a second value smaller than the first value while the curved road has been determined to be present to perform the acceleration-deceleration control.

  • Patent number: 11752881
    Abstract: A method of operating a vehicle includes a vehicle controller receiving an operator-input vehicle control command with an associated torque request, and identifying any propulsion actuator constraints that limit a brake torque capacity available from the vehicle powertrain. Using the propulsion actuator constraint(s) and torque request, the controller determines a propulsion brake torque distribution for the vehicle's road wheels and a maximum brake torque capacity for the powertrain actuator(s). A first brake torque request is determined using the propulsion brake torque distribution and a vehicle control mode of the powertrain system, and a second brake torque request is determined using the maximum brake torque capacity and the vehicle control mode. A friction brake torque command is determined by arbitrating between the first and second brake torque requests.
