    Abstract: A vehicle control device controls a vehicle on the basis of a detection time representing a distance measured by a range finder device. The range finder device is installed in the vehicle to measure a distance to an object around the vehicle by transmitting and receiving sound waves. The vehicle control device includes a processor that receives an input of a first detection time after movement of the vehicle. The processor outputs an intersection point as coordinates indicating a position of the object when the intersection point is obtained. The intersection point is a point at which an estimated straight line and a first locus intersect. The estimated straight line connects respective positions of the range finder device before and after the movement of the vehicle. The first locus is based on the first detection time.

    Abstract: The present disclosure discloses a trailer braking control method and system based on an electric brake controller. A lateral displacement and speed of a vehicle are acquired first; whether the vehicle has Death Wobble and a degree of the Death Wobble are then determined according to the lateral displacement; if there is Death Wobble, a driving state of the vehicle is determined according to the speed; and finally, a set voltage is added based on a set output voltage according to the degree of the Death Wobble and the driving state, so as to brake the vehicle. The present disclosure avoids setting of a weight ratio in the prior art to prevent the phenomenon of Death Wobble, and can identify and prevent the phenomenon of Death Wobble of a trailer, thereby avoiding an overturning accident and ensuring the personal safety and the integrity of a vehicle.

    Abstract: An HEV-CU determines whether a traveling state requires giving priority to a front and rear driving force control (e.g., whether a vehicle is cornering) on the basis of a traveling state of the vehicle. If the traveling state requires giving priority to the front and rear driving force control (e.g., the vehicle is cornering), the HEV-CU-preferentially controls of an engine and a motor generator as well as engagement force of a differential limiting clutch in accordance with friction force between front and rear wheels and a road surface. If the traveling state does not require giving priority to the front and rear driving force control (e.g., the vehicle is traveling straight), the HEV-CU preferentially controls the driving of the motor generator to cause a charged state (SOC) of a high-voltage battery that supplies electric power to the motor generator to fall within a predetermined range.

  • Publication number: 20240300476
    Abstract: A drive control apparatus for an electric vehicle includes a controller that controls an engine, a traveling motor, a transmission, and an output clutch. The controller estimates the rotation angle of the motor by a first estimation method and controls the motor on the basis of the estimated angle. The estimation method is executable when the rotation speed of the motor is a threshold or higher. When a rotation angle sensor for the motor is in an abnormal state and a specific driving state is present, the controller controls one or more of the engine, the transmission, and the output clutch differently from when the sensor is in a normal state, and thereby maintains the rotation speed at the threshold or higher. The specific driving state is a state in which the rotation speed is lower than the threshold under the control when the sensor is in the normal state.

  • Publication number: 20240300497
    Abstract: A method for operating a drive train of a motor vehicle, where the drive train includes a drive aggregate, a group transmission connected between the drive aggregate and a drive output, and a separating cutch connected between the drive aggregate and the group transmission. If a speed is lower than a limit value, the separating clutch is opened and for transmission preselection one or all the other sub-transmission(s) is/are changed to a friction-force-locking condition. The separating clutch is then at least partially closed and the drive aggregate is brought to a defined rotation speed. When a friction-force-locking group transmission is required, it is checked whether a starting gearshift or a driver-desired shift for the group transmission is called for and the target rotation speed of the drive aggregate is checked. Depending on the results, the sub-transmission can be synchronized by a transmission brake or by the drive aggregate.

    Abstract: A processor, responsive to a set of location or motion data describing one or more objects relative to a first, local frame of reference, generates a transformed set of location or motion data describing the one or more objects relative to a second, local frame of reference different than the first local frame of reference, such that the set of location or motion data and the transformed set of location or motion data relative to a global frame of reference are same. The processor also outputs the transformed set of location or motion data to a vehicle such that the vehicle performs control operations responsive thereto.

    Abstract: Provided is a technology capable of adding a new function by updating a program of an in-vehicle computer system. An in-vehicle computer system includes a plurality of ECUs. Each ECU is able to communicate with at least one other ECU via a communication bus. An in-vehicle computer system includes a measurement means that measures an ECU state for the ECUs, an estimation means that estimates a vehicle state based on the ECU state and a connection configuration of a communication bus, and a management means that acquires an update program and execution conditions of the update program. The management means selects a first ECU that is to execute the update program based on the vehicle state and the execution conditions. The first ECU executes the update program. The management means determines whether or not an output delay constraint of the update program is satisfied. The management means terminates execution of a redundancy program redundant to the update program.

  • Publication number: 20240300503
    Abstract: Methods, systems, and apparatuses are provided for controlling longitudinal and/or lateral guidance of a vehicle. A trajectory planner is configured to ascertain setpoint trajectory variables for a trajectory of the vehicle. The setpoint trajectory variables include a first trajectory state and a second trajectory state. The second trajectory state corresponds to a change in the first trajectory state over time. A feed-forward controller is configured to calculate a feed-forward control variable from the setpoint trajectory variables and from a model of dynamic behavior of the vehicle. The feed-forward control variable and the first trajectory state are variables of the same type. The device is configured to use the feed-forward control variable as a basis for determining a manipulated variable for a controlled system within the scope of the longitudinal and/or lateral guidance. The manipulated variable and the feed-forward control variable are variables of the same type.

    Abstract: The disclosure relates to a method for calculating a setpoint value curve for an intervention in an operation of a vehicle component of a vehicle in order to set an operating variable to a target value in the vehicle component. The operating variable is cyclically compared with a start value, and if it is detected that the operating variable has the start value, a setpoint trajectory for setting the operating variable along a time curve in accordance with a predetermined curve shape to the target value starts by an intervention in a manipulated variable which acts on the operating variable.

  • Publication number: 20240300506
    Abstract: A computer-implemented method for providing safe control inputs for actuator components of a vehicle for implementing a specified trajectory. A vehicle state is determined at a first time, and a first set of control inputs for the first time is provided. It is then checked whether the first set of control inputs is safe by checking whether the vehicle state predicted based on the vehicle state and the first set of control inputs for a later second time is safe. The predicted vehicle state is considered safe if it is within a predetermined maximum controlled invariant state set. If the vehicle state is not considered safe, a safe set of control inputs is determined, by modifying the first set of control inputs such that the vehicle state predicted based on the vehicle state and the modified set of control inputs is considered safe.
